Answer:
Approx. 73°
Step-by-step explanation:
Express the numbers in scientific notation:
1. 75000
2. 0.0024
3. 75,000,000
4. 0.0000024
Answer:
1. 75000 ⇒ 7.5 × [tex]10^{4}[/tex]
2. 0.0024 ⇒ 2.4 × [tex]10^{-3}[/tex]
3. 75,000,000 ⇒ 7.5 × [tex]10^{7}[/tex]
4. 0.0000024 ⇒ 2.4 × [tex]10^{-6}[/tex]
Step-by-step explanation:
Scientific notation is a way of writing very large or very small numbers.
A number is written in scientific as a number between 1 and 10 and multiplied by a power of 10
The form of the scientific notation is a × [tex]10^{n}[/tex], where
1 < a < 10n is an integern is positive if the decimal point moves from right to leftn is negative if the decimal point moves from left to right1. 75000
→ Place a decimal point between 7 and 5 to make the number between
1 and 10
∴ a = 7.5
→ Count the number of the digits right to the decimal point
∵ There are 4 digits right to the decimal point
∴ n = 4
∴ 75000 ⇒ 7.5 × [tex]10^{4}[/tex]
2. 0.0024
→ Move the decimal point from left to right to place it between 2 and 4 to
make the number between 1 and 10
∴ a = 2.4
→ Count the number of the digits left to the decimal point
∵ There are 3 digits left to the decimal point
∴ n = -3
∴ 0.0024 ⇒ 2.4 × [tex]10^{-3}[/tex]
3. 75,000,000
→ Place a decimal point between 7 and 5 to make the number between
1 and 10
∴ a = 7.5
→ Count the number of the digits right to the decimal point
∵ There are 7 digits right to the decimal point
∴ n = 7
∴ 75,000,000 ⇒ 7.5 × [tex]10^{7}[/tex]
4. 0.0000024
→ Move the decimal point from left to right to place it between 2 and 4 to
make the number between 1 and 10
∴ a = 2.4
→ Count the number of the digits left to the decimal point
∵ There are 6 digits left to the decimal point
∴ n = -6
∴ 0.0000024 ⇒ 2.4 × [tex]10^{-6}[/tex]

PLS HELP FIND ANGLE MEASUREMENTS
Answer:
From my observations, AOB looks like an isosceles triangle, so A=18 and B=18. Since a triangle must add up to 180. We do 180-18-18=144. O= 144. Then, triangle BOC looks like an isosceles triangle as well. So, we do 180-144= 36 so O = 36 and then we 180-36=144/2 because two sides have the same angles giving us 72 degrees for angles B and C = 72 and for O= 36
So,
x = 72
y = 36
In the diagram, Find the value of y
Answer:
y = 42
Step-by-step explanation:
we can start by getting teh degree of x
62 + 65 = 127
180 - 127 = 53
x = 53
x - y = 11
we know that 53 is x
53 - y = 11
y = 42

If f(x)=2x^3+4x^2, find f(-3)
Answer:
f(-3) = -18
Step-by-step explanation:
f(x)=2x^3+4x^2, find f(-3); let's rewrite
f(x) = 2[tex]x^{3}[/tex] + 4[tex]x^{2}[/tex]; substitute -3 for x
f(-3) = 2[tex](-3)^{3}[/tex] + 4[tex](-3)^{2}[/tex]; do the exponents
f(-3) = 2(-27) + 4(9); multiply and add
f(-3) = -54 + 36 = -18
The value of the function f(x) = 2x³ + 4x² at f(-3) is - 18.
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, A function f(x) = 2x³ + 4x².
Now, The value of the function f(-3) can be obtained by replacing
x with - 3.
Therefore, f(-3) = 2(-3)³ + 4(-3)².
f(-3) = 2×-27 + 4×9.
f(-3) = - 54 + 36.
f(-3) = - 18.

Wilscy owns a toy store. The number of toy trains sold (in thousands) from 2000 through 2005 can be modeled by M(x) = −0.5x3 + 2x2 − x + 9. The average cost per toy train (in dollars) can be modeled by N(x) = 0.3x + 7, where x represents the number of years since 2000. The total revenue Wilscy made by the sale of toy trains is the product of the number of toy trains sold and the average cost per toy train. Identify a polynomial P(x) that can be used to model the total revenue.
Options:
a: P(x) = −0.15x4 − 2.9x3 + 13.7x2 − 4.3x + 63
b: P(x) = −0.5x3 + 2x2 − 0.7x + 2

Jeff mowed a lawn for $20.00 and received a $5,25 tip. He then washed a car for $12.50. How much money
did Jeff make for completing these two jobs?
Answer:
See below.
Step-by-step explanation:
Mowing the lawn: $20
Tip: $5.25
Add them together.
[tex]20+5.25=25.25[/tex]
Washing the car: $12.50
Add that to the amount.
[tex]25.25+12.50=37.75[/tex]
Answer: [tex]37.75[/tex]
:)
Answer "and" Explanation:
Depends on whether this is a simple math problem or a riddle. I’m assuming the latter so…
Jeff received $20.00 for providing a lawn mowing service. Jeff received an additional $5.25 tip. Ignoring costs and taxes, Jeff’s gross receipts were $25.25.
Jeff then decided to wash a car. The ways it’s worded leads me to believe he spent $12.50 on the car wash.
So, $25.25 - $12.50 = $12.75
Alternatively, if Jeff was paid to wash the car then:
$20.00 + $5.25 + 12.50 = $37.75
So the Answer will be: $37.75

Answer:
Slope: 6 Y-intercept: 2
Step-by-step explanation:
See where the line hits perfectly at an age and calculate rise/run. Here the rise is 6 and the run is 1, therefore 6/1 = 6.
Where is the y value that equals 0 in the x value? Right in the middle of the y line, so its 2. Hope this makes sense, I’m not too good at explaining stuff lol

Well AOB + BOC = AOC so...
4x - 1 + 2x + 15 = 8x + 8 (collect like terms)
6x + 14 = 8x + 8 (subtract 8 on each side)
6x + 6 = 8x (subtract 6x on both sides)
6 = 2x (divide by 2 on both sides)
3 = x
#8
COD + BOC = BOD so..
8x + 13 + 3x - 10 = 12x - 6 (collect like terms)
11x + 3 = 12x - 6 (add 6 on both sides)
11x + 9 = 12x (subtract 11x on both sides)
9 = x
Hope this helps!!
