Answer:
In step 5, andrew made a mistake by subtracting 9.8 instead of adding 9.8. Andrew should've have obtained the answer -2, but because of his mistake the answer is incorrect.
the radius of the distance between the middle point of the circle and the outside, we have the diameter which is 6 so the <u>radius will be 3</u>
slant height is
h is 4.7 and r is 3
<u>slant height is 5.58427</u>
lateral surface area
<u>lateral surface area is 52.63053</u>
total surface area
<u>total surface area is 80.90486</u>
Answer:
A and C
Step-by-step explanation:
solving the equations
A
x² - 4 = 0 ( add 4 to both sides )
x² = 4 ( take square root of both sides )
x = ± = ± 2 ← required solution
B
x² = - 4 ← has no real solutions
C
4x² = 16 ( divide both sides by 4 )
x² = 4 ( take square root of both sides )
x = ± = ± 2 ← required solution
D
2(x - 2)² = 0 , then
x- 2 = 0 ( add 2 to both sides )
x = 2 ← not the required solution
Horizontal, it’s below a 1/2 slope.
