we are given
we are given relation between speed and distance
distance ( when speed =70mph) is
=328feet
so,
distance ( when speed =50mph) is
=183feet
so,
now, we can find percentage in decrease

now, we can plug values

%...........Answer
The measure side UV will equal 11 if triangle TUV is dilated by a scale factor 1/3 having a side U'V'=33.
<h3>What is the scale factor?</h3>
The scale factor is the ratio of the length of a side of one figure to the length of the corresponding side of the other figure. It is a process of enlarging the image of an object by some factor.
here we have the scale factor

Since the triangle, TUV is dilated by the scale factor 1/3 then the sides of triangle will also be in the same dilation so we can write.



Hence the measure side UV will equal 11 if triangle TUV is dilated by a scale factor 1/3 having a side U'V'=33.

Answer:
3x² – 5x + 10
Step-by-step explanation:
(4x² – 2x + 8) - (x² + 3x - 2) =
Drop the first set of parentheses because it is unnecessary.
= 4x² – 2x + 8 - (x² + 3x - 2)
To get rid of the second set of parentheses, change every sign inside.
= 4x² – 2x + 8 - x² - 3x + 2
Now, combine like terms.
= 3x² – 5x + 10
Answer:
154
Step-by-step explanation:
Because since it says find f(7) you plug the 7 into the x's so it would be...
4(7)^2-7(7)+7= 154
