Answer:
The final answers are:


Step-by-step explanation:
-The equation:

Use the Quadratic Formula:


-Then, you solve:

-Multiply -7 by the exponent 2:

-Multiply to the 4 and the 2:

-Distribute -4 by 8:

-Add 49 and 32 together:

-Take the square root of 81:

-The opposite of -7 is 7:

-Multiply 2 times 2:

-Add both the 7 and 9:

-Divide 16 by 4 to get 4:

So, the first answer  and you need to find the second answer.
 and you need to find the second answer.
-To find the second answer, you to reduce the fraction to lowest terms and canceling out the 2:


So, the second answer is  .
.
-The results are:


 
        
             
        
        
        
Answer:
41.7feet
Step-by-step explanation:
From the question we are given the following
angle of depression = 50°
Distance of the pole from the base of the feet = 35feet (Adjacent)
Required
height of the school (opposite)
Using the SOH CAH TOA identity
Tan theta = opp/adj
Tan 50 = H/35
H = 35tan 50
H = 35(1.1918)
H = 41.7feet
Hence the height of the school is 41.7feet
 
        
             
        
        
        
So 37 1/2
each can hold 2 1/2 oz
how many cups can he fill
37 1/2=75/2
2 1/2=5/2
x=number of cups
x times 5/2=75/2
5/2x=75/2
multiply both sides by 2
5x=75
divide both sides by 5
x=15
he can fill 15 cups
