Answer:
x = ± 15
Step-by-step explanation:
Given f(x) = - 0.5x² and f(x) = - 112.5 , then equate right sides
- 0.5x² = - 112.5 ( divide both sides by - 0.5 )
x² = 225 ( take square root of both sides )
x = ± 
= ± 15
<h2>Solving for the measurements of Complementary Angles</h2><h3>Answer:</h3>
and 
<h3>Step-by-step explanation:</h3>
Recall that Angles that are supplementary to each other add up to 
.
Let 
be the measure of the supplementary angle.
If an angle is 
more than its supplementary angle, the measure of that angle is 
. The sum of both angles are expressed 
but since the have to add to 
as they are supplementary, 
.
Solving for :
Since the other angle measures , we can plug in the value of to find the measure of the angle.
Evaluating :
The measure of the angles are and
x = 8/7
hope this helps on whatever you are doing!
Its 1.25
since the fraction is out of fourths, consider it as a quarter. 1 quarter equals .25
and the whole is 1 whole dollar. 1 whole dollar is made up of 4 quarters.
there for 1 1/4 is equal to 1.25
