The following are infinite geometric series. For which infinite series could find the sum using a formula?

A) -2+6+(-18)+54+(-162)+...

B) 3+12+48+192+768+...

C) 1+2+4+8+16+...

D) 8+4+2+1+1/2+...

Answers

Answer 1

Answer:

D)  8 + 4 + 2 + 1 + 1/2 + ...

Step-by-step explanation:

The sum of an infinite geometric series can be found when the absolute value of the common ratio, r, is less than 1.

[tex]\boxed{\begin{minipage}{5.5 cm}\underline{Sum of an infinite geometric series}\\\\$S_{\infty}=\dfrac{a}{1-r}$,\quad $|r| < 1$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the first term. \\ \phantom{ww}$\bullet$ $r$ is the common ratio.\\\end{minipage}}[/tex]

To determine which of the given infinite geometric series can be summed using the formula, calculate the value of r for each series.  To do this, divide a term by the previous term.

Given infinite geometric series:

-2 + 6 + (-18) + 54 + (-162) + ...

[tex]\implies r=\dfrac{6}{-2}=-3[/tex]

As r is not in the interval −1 < r < 1, the sum of the infinite series cannot be found using the formula.

Given infinite geometric series:

3 + 12 + 48 + 192 + 768 + ...

[tex]\implies r=\dfrac{12}{3}=4[/tex]

As r is not in the interval −1 < r < 1, the sum of the infinite series cannot be found using the formula.

Given infinite geometric series:

1 + 2 + 4 + 8 + 16 + ...

[tex]\implies r=\dfrac{2}{1}=2[/tex]

As r is not in the interval −1 < r < 1, the sum of the infinite series cannot be found using the formula.

Given infinite geometric series:

8 + 4 + 2 + 1 + 1/2 + ...

[tex]\implies r=\dfrac{4}{8}=\dfrac{1}{2}[/tex]

As |r| < 1 the sum of the infinite series can be found using the formula.

Therefore, the infinite series for which the sum can be found by using the formula is:

D)  8 + 4 + 2 + 1 + 1/2 + ...

hailey invested $940 with an interest rate of 8.25 % that is compounded quarterly and Justin invested $940 with an interest rate of 7.625% that is compounded monthly

To the nearest dollar, how much money would Hailey have in her account when Justin's money has tripled in value?

Answers

To solve this problem, we need to first determine how long it will take for Justin's money to triple in value. We can use the formula for compound interest:

A = P(1 + r/n)^(nt)

where:

A = the final amount

P = the principal (initial amount)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the number of years

For Justin, we have:

P = $940

r = 0.07625

n = 12 (monthly compounding)

t = unknown

We want to solve for t when A = 3P = $2820. We can rearrange the formula and plug in the values:

A = P(1 + r/n)^(nt)

3P = P(1 + r/n)^(nt)

3 = (1 + 0.07625/12)^(12t)

ln(3) = 12t * ln(1 + 0.07625/12)

t = ln(3) / (12 * ln(1 + 0.07625/12))

t ≈ 15.8 years

So it will take Justin about 15.8 years for his money to triple in value.

Now we can use the same formula to find how much money Hailey will have in her account after 15.8 years:

P = $940

r = 0.0825

n = 4 (quarterly compounding)

t = 15.8

A = P(1 + r/n)^(nt)

A = $940(1 + 0.0825/4)^(4*15.8)

A ≈ $3501

Therefore, Hailey will have about $3,501 in her account when Justin's money has tripled in value

The probability that a person who walked also sailed is 1/8.

Describe Probability?

Probability is used to make predictions about the likelihood of future events, based on past observations or available information. It is widely used in fields such as statistics, finance, engineering, and science to analyze and model uncertain systems and processes.

Out of the 50 people, 3 did not participate in either walking or sailing. So, the number of people who participated in at least one activity is:

50 - 3 = 47

Out of these 47 people, 40 took part in walking and 18 took part in sailing. However, we need to subtract the number of people who participated in both activities because we don't want to count them twice. Let's call this number "x":

x = number of people who participated in both walking and sailing

So, the number of people who participated in at least one of the activities is:

40 + 18 - x

We know that there were 50 people in total, so we can write:

40 + 18 - x + 3 = 50

Simplifying this equation, we get:

55 - x = 50

x = 5

So, 5 people participated in both walking and sailing.

Now, we want to find the probability that a person who walked also sailed. Since there were 40 people who walked and 5 of them also sailed, the probability is:

5/40 = 1/8

Therefore, the probability that a person who walked also sailed is 1/8.

Answers

Step-by-step explanation:

law of cosine

c² = a² + b² - 2ab×cos(C)

c is the side opposite of the C angle. a and b are the other 2 sides.

AB² = 4² + 4² = 16 + 16 = 32

AB = c = sqrt(32) = 5.656854249...

since a and b are equal (isoceles triangle), so must be the angles at A and B.

the sum of all angles in a triangle is always 180°.

180 = angle A + angle B + angle C

= angle A + angle B + 120

since angle A = angle B we get

180 = 2×angle A + 120

2×angle A = 60°

angle A = angle B = 30°.

18 people entered the race 2 people didn’t finish what is the ratio of those who finished the race to those that entered

Answers

The ratio of those who finished the race to those that entered will be 8:9.

What is ratio?

For evaluating the relationship between two numbers or quantities, we employ the ratio formula. The general manner of representing a ratio of between two quantities say 'a' and 'b' is a: b, which is interpreted as 'a is to b'.

A ratio describes how much of one quantity is necessary in relation to another. It is possible to combine and express the two terms in the ratio in their simplest form.

Given : total people entered = 18

           people didn't finish = 2

So, people who finished = total people entered - people didn't finish

                                         = 18 - 2

                                         = 16

Hence, Ratio required = people who finished race / people who entered

                                     = 16 / 18

                                     = 8/9

A certain forest covers an area of 2100 km sq. Suppose that each year this area decreases by 4%. What will the area be after 10 years?
round your answer to the nearest square kilometer.

Answers

The area of the forest will be approximately 1396 km sq. after 10 years.

What will the area be after 10 years?

Given that, a forest covers an area of 2100 km sq and that each year this area decreases by 4%..

Initial value = 2100rate = 4%Elapsed time = 10 years

If the area of the forest decreases by 4% each year, then after one year it will be 96% of the original size.

After two years, it will be 96% of 96% of the original size, or 0.96² of the original size.

After ten years, it will be 96% of itself ten times, or 0.96¹⁰ of the original size.

So the area of the forest after 10 years will be:

Area = Initial area × 0.96¹⁰

Area = 2100 km sq × 0.96¹⁰

Area = 1396 km sq

Therefore, the area of the forest cover in 10 years will be 1396 km sq.

The number 3 in the equation h(t) = -16t² + 6t+ 3 represents the initial height from which the ball is thrown.

The equation h(t) = -16t² + 6t+ 3 models the height of the ball thrown in the air, with h(t) measured in feet and time, t, measured in seconds. The number 3 in this equation refers to the height from which the ball is thrown. This is represented by the constant term 3, which is added to the equation after the sum of the variables. The formula h(t) = -16t² + 6t+ 3 can be broken down into three parts. The first part is the constant term, 3, which denotes the initial height of the ball. The second part is the linear term, 6t, which represents the acceleration of the ball due to gravity. Lastly, the quadratic term, -16t², is used to describe the rate at which the ball’s acceleration slows down due to air resistance. Therefore the number 3 in the equation h(t) = -16t² + 6t+ 3 represents the initial height from which the ball is thrown.

Answers

Answer:

None of it.

Step-by-step explanation:

Notice the slope is 2.75 this means for EVERY X the graph goes up by 2.75 in the Y axis. For example.
If at                 X=1     y=0
Then for         X=2   y=2.75

and for            X=3  y=2.75+2.75=5.5
also the graph must pass thought point (0,0), the origin, and none of the graph follow this.  

You can also compare the slopes of each equations
for graph A, from x=1 to x=2 the height Y goes from 3 to 3.5, this is a slope of 0.5 (not the 2.75 we are looking for)

for graph A, from x=1 to x=2 the height Y goes from 1 to 2.5, this is a slope of 1.5 (not the 2.75 we are looking for)

for graph A, from x=1 to x=2 the height Y goes from 1 to 2.75 this is a slope of 1.75 (not the 2.75 we are looking for)

given the line 4x+5y-9=0 find the gradient , intercept y and intercept x and sketch line

Answers

According to given conditions, Gradient = -4/5, y-intercept = 9/5, x-intercept = 9/4.

What is co-ordinate geometry ?

Coordinate geometry is a branch of mathematics that deals with the study of geometric shapes using a coordinate system. In this system, points are identified by their positions in relation to two or more perpendicular lines called axes.

To find the gradient and intercepts of the line 4x+5y-9=0, we need to rearrange the equation into the slope-intercept form y=mx+b, where m is the slope and b is the y-intercept.

First, we can solve for y:

4x + 5y - 9 = 0

5y = -4x + 9

y = (-4/5)x + 9/5

Now we can see that the slope (m) of the line is -4/5 and the y-intercept (b) is 9/5. To find the x-intercept, we can set y=0 and solve for x:

(-4/5)x + 9/5 = 0

-4x + 9 = 0

x = 9/4

So the x-intercept is (9/4, 0).

To sketch the line, we can plot the y-intercept at (0, 9/5), the x-intercept at (9/4, 0), and draw a straight line passing through both points:

Therefore, according to given conditions, Gradient = -4/5, y-intercept = 9/5, x-intercept = 9/4.

Rectangle abcs is the image of rectangle abcs after t abcs if a is (6,-8) a is (-2,4) and (4,-6)what are coordinates of b

Answers

In the rectangle , the cοοrdinate οf b is (0,2).

What is rectangle?

A quadrilateral with fοur equal vertices and parallel sides is knοwn as a rectangle. Because οf this, it is alsο knοwn as an equiangular quadrilateral.

The term "parallelοgram" can alsο be used tο describe a rectangle because the οppοsing sides are equal and parallel.

Here In the given rectange abcd,  Let cοοrdinates οf b be (x, y)

then, ac and bd are diagοnals οf the rectangle.

Coordinates of midpoints of ac and bd must be same.

Coordinates of midpoint of ac = [tex](\frac{6-2}{2},\frac{-8+4}{2})[/tex] = [tex](\frac{4}{2},\frac{-4}{2})[/tex] = (2,-2)

Coordinates of midpoint of bd = [tex](\frac{x+4}{2},\frac{y-6}{2}) = (2,-2)[/tex]

=> [tex]\frac{x+4}{2}=2 , \frac{y-6}{2}=-2[/tex]

=> x+4=4 , y-6=-4

=> x=4-4, y=-4+6

=> x=0,y=2

Hence the coordinate of b is (0,2).

Using the diagram below, which of the following angle pairs represent vertical angles?

A) ∠KDJ ≅ ∠FBG
B) ∠LAC ≅ ∠GBC
C) ∠DCE ≅ ∠BCA
D) ∠DCE ≅ ∠BCE

Answers

The following angle pairs represent vertical angles (C) ∠DCE ≅ ∠BCA.

What is Vertically Oppοsite Angle?

Vertical angles are a pair οf nοn-adjacent angles fοrmed by the intersectiοn οf twο lines. Vertical οppοsite angles are a type οf vertical angles that are acrοss frοm each οther and have the same measure. In οther wοrds, if twο lines intersect at a pοint, then the angles that are οppοsite each οther (i.e., οne οn the left and οne οn the right οf the intersectiοn) are called vertical οppοsite angles, and they are cοngruent.

Vertical angles are fοrmed by the intersectiοn οf twο lines. They are cοngruent, which means they have the same measure.

Lοοking at the diagram, we see that angles ∠KDJ and ∠FBG are nοt fοrmed by the intersectiοn οf twο lines. They are bοth interiοr angles οf the quadrilateral KDFB. Therefοre, they are nοt vertical angles.

∠LAC and ∠GBC are nοt fοrmed by the intersectiοn οf twο lines. They are bοth interiοr angles οf the quadrilateral KDFB. Therefοre, they are nοt vertical angles.

Angles ∠DCE and ∠BCA are fοrmed by the intersectiοn οf twο lines, and they are οn οppοsite sides οf the transversal AC. Therefοre, they are vertical angles, and chοice (C) is the cοrrect answer.

Angles ∠DCE and ∠BCE share a cοmmοn ray, CE, but they are nοt fοrmed by the intersectiοn οf twο lines. Therefοre, they are nοt vertical angles.

Sο the cοrrect answer is (C) ∠DCE ≅ ∠BCA.

Lim. Sin(1/theta)
Theta-0

Answers

Answer:

the limit of sin(1/θ) as θ approaches 0 is equal to 0.

Step-by-step explanation:

To evaluate this limit:

lim θ→0 sin(1/θ)

we can use the squeeze theorem. First, we note that -1 ≤ sin(1/θ) ≤ 1 for all values of θ, since the sine function oscillates between -1 and 1.

Next, we consider the limit of two other functions, -1/|θ| and 1/|θ|, as θ approaches 0:

lim θ→0 -1/|θ| = -∞

lim θ→0 1/|θ| = ∞

Since sin(1/θ) is always between -1/|θ| and 1/|θ|, we can apply the squeeze theorem to conclude that:

lim θ→0 sin(1/θ) = 0

Therefore, the limit of sin(1/θ) as θ approaches 0 is equal to 0.

Lisa is going on a 3 1/2 mile hike. She has already hiked 2 3/4 miles How many miles does she have left?

Answers

Answer:

3/4 miles

Step-by-step explanation:

Parameters

Total distance = 3 1/2 miles

Covered distance = 2 3/4 miles

To make things easier let's convert our parameters from fraction to decimal,

Therefore,

Total distance= 3.5 miles

Covered distance = 2.75 miles

Remaining distance = Total distance - Covered distance

Remaining distance = 3.5 miles - 2.75 miles

Remaining distance= 0.75 miles

Converting back to fraction,

Remaining distance = 3/4 miles

Therefore,

Lisa has 3/4 miles left to hike.

Answer:

The y-intercept represents a starting salary of $32,500.

The slope represents an additional $2,500 in salary for each additional year of employment.

If the starting salary for a new employee is changed to $35,000 and the yearly salary increase is unchanged, the new equation would be
[tex]y=2500x+35000[/tex].

If the yearly salary increase is changed to $3,000 and the starting salary remains the same, the new equation would be
[tex]y = 3000x + 32500[/tex].

Step-by-step explanation:

Answer:

The y-intercept represents a starting salary of $32,500.

The slope represents an additional $2,500 in salary for each additional year of employment.

If the starting salary for a new employee is changed to $35,000 and the yearly salary increase is unchanged, the new equation would be

y=2500x+35000y=2500x+35000 .

If the yearly salary increase is changed to $3,000 and the starting salary remains the same, the new equation would be

y = 3000x + 32500y=3000x+32500 .
