1. he slope of a line through the points (-2, 4) and (6, b) is -3/2 What is the value of b?
Explain your method for calculating b.

Answers

Answer 1

Answer:

Step-by-step explanation:

Use the slope formula to solve this problem. Slope, usually called m, is the change in y-values over the change in x-values.

m = (y2 - y1)/(x2 -x1)

It actually doesn't matter which point is the first point and which point is the second point. But you must be consistent.

So fill in -3/2 for the m

Let your (6, b) be your (x1, y1)

Let (-2, 4) be your (x2, y2)

So, the numbers fill into the formula like so:

-3/2 = (4 - b)/ (-2 - 6)

-3/2 = (4 - b)/(-8)

Multiply -8 on both sides of the equation.

(-8)(-3/2) = 4 - b

12 = 4 - b

Subtract 4 from both sides.

Don't lose the negative in front of the b

8 = -b

Multiply or divide by -1 on both sides.

-8 = b This is the answer.

**note: Its kinda crummy to use b in this equation, because b has a special meaning when you are working with linear equations. They should have given you a different variable. b usually stands for the y-intercept but in this problem it doesn't, it's just a variable representing an unknown value.

Answers

Step-by-step explanation:

first we use Pythagoras to get t :

c² = a² + b²

with c being the Hypotenuse.

so,

t² = r² + s² = 10² + 31² = 100 + 961 = 1061

t = sqrt(1061)

and then we use the law of sine :

a/sin(A) = b/sin(B) = c/sin(C)

with the angles being opposite of their related sides.

so, r/sin(R) = t/sin(T) = t/sin(90) = t/1 = t

sin(R) = r/t = 10/sqrt(1061) = 0.30700278...

R = 17.8786966... ≈ 17.9°

Step-by-step explanation: f(x) is the same as y. The formula for a line is slope-intercept form (y=mx+b). The -2 is the y-intercept, and the line intercepts the graph at -2. The slope is -3/2 because it rises 3 and goes to the left -2.

can someone please explain this question

Answers

Sure thing!

So if we look at the function, it is an exponential, meaning that it is a number to the power of x
The graph can be described by the equation

y = a^x

If we look at the graph, one of the points on the line is (2, 16), the x value is 2 and the y value is 16

If we consider this along with the function for the graph, we can say that

16 = a^2

Just solve this for a and you’ll have your answer :)
So the answer is 15

An auto insurance company classifies each motorist as "high risk" if the motorist has had at least one moving violation during the past calendar year and "low risk" if the motorist has had no violations during the past calendar year. According to the company's data, a high-risk motorist has a 50% chance of remaining in the high-risk category the next year and a 50% chance of moving to the low-risk category. A low-risk motorist has a 90% chance of moving to the high-risk category the next year and a 10% chance of remaining in the low-risk category. In the long term, what percentage of motorists fall in each category? (Round your answers to two decimal places.)

high-risk category %
low-risk category %

Answers

The percentage of motorists falling in each category, in the long term, are as follows:

High-risk category = 70%

Low-risk category = 30%

Data and Calculations:

Risk Profile Categories of Motorists

                                                       High Risk      Low Risk

Probability of remaining

 in the same category                      50%              10%

Probability of moving to another

 category                                          50%              90%

Probability a motorist falling in the high-risk category = (50% x 50%) + (50% x 90%)

= 25% + 45%

= 70%

Probability a motorist falling in the low-risk category = (50% x 50%) + (50% x 10%)

= 25% + 5%

= 30%

Thus, the probability of a motorist falling in the high-risk category is 70%, while the probability of a motorist falling in the low-risk category is 30%.

5. Reasoning ＀e scale of a map is 1 in. : 100 mi. Is the actual distance between two towns 100 times the map distance between the two towns? Explain.

Answers

Similar triangles may or may not have congruent sides, but the ratio of the corresponding sides will always be congruent.

(3) Corresponding sides of △MNP and △RST

Given that △MNP ∼△RST.

This means that, the corresponding sides are:

MN and RSMP and RTNP and ST

(4) The equal measures

Given that △ABC ∼△TUV

This means that, the corresponding angles are equal, but corresponding sides are not.

So, the equal measures are:

(a). the measures of ∠A and ∠T (c). the ratios of the sides BC/UV and AC/TV

The unequal measure is:

(b). the perimeters of the two triangles

(c) Scale mapping

The scale mapping is given as:

[tex]Ratio = 1\ in : 100\ mi[/tex]

The above scale means that 1 inches on the scale represents 100 miles of the actual distance.

Take for instance, 5 inches would represent 500 miles.

500 is 5 times 100

Hence, the actual distance between two towns 100 times the map distance between the two towns

By Green's theorem (all the conditions are met), we have

[tex]\displaystyle \int_C \sqrt y \, dx + \sqrt x \, dy = \iint_D \frac{\partial(\sqrt x)}{\partial x} - \frac{\partial(\sqrt y)}{\partial y} \, dx \, dy[/tex]

[tex]D = \left\{ (x, y) : 0 \le y \le \dfrac{x^2}2 \text{ and } 0 \le x \le 2 \right\}[/tex]

So, the line integral reduces to the double integral,
