Answer:
The answer is -80
Step-by-step explanation:
The average rate of change is also the slope from the endpoints. The two points are (0,500) to (5, 100). To find the average rate of change between those points, use the formula: change of y over the change of x.
Answer
Find out the how much did kerry pay in tax .
To proof
As given
Kerry bought a bag of dog food for $37.99.
If sales tax is 7.6%
7.6 % is written in the decimal form
= 0.076
7.6 % of the $37.99 = 0.076 ×37.99
= 2.88724
= $2.89 ( approx)
Kerry pay in the sales tax be $2.89
Hence proved
Hello!
We are given that the measure of one angle is equal to 115 degrees (for convenience, we’ll refer to this angle as ∠W). Looking at the image above, we can see that ∠W and ∠Y are supplementary angles. Supplementary angles are two angles whose measures add to a sum of 180 degrees, also known as a straight line. This relationship can be expressed using the following formula:
A1 + A2 = 180
Now insert any known values provided by the image above:
(115) + (∠Y) = 180
Subtract 115 from both sides of the equation:
∠Y = 65
We have now proven that ∠Y has a measure of 65 degrees. Now, looking at the image again, we can see that ∠W and ∠X are vertical angles. Vertical angles are two angles that lie on opposite sides of two intersecting lines. A pair of vertical angles is always equal in measure. This relationship can be expressed using the following formula:
A1 = A2
Now insert any known values provided by the image above:
(∠X) = (115)
We have now proven that ∠X has a measure of 115 degrees.
I hope this helps!
Answer: 5
Step-by-step explanation:
a^2 + b^2 = c^2
12^2 + x^2 = 13^2
144 + x^2 = 169
x^2 = 25
square root both sides
x = 5
to check, do 12^2 + 5^2 =169
sqrt of 169 is 13
hope this helps
Answer:
9
Step-by-step explanation:
substitute the x which is x= 2, so
f(2)= (2+1)^2
=(3)^2
=9
