Answer:
C. 9
Step-by-step explanation:
3n - 18 = 9
3n (- 18 + 18) = 9 + 18
3n = 27
3n/3 = 27/3
n = 9
Answer:
1.8m²
Step-by-step explanation:
∅= 51× π/180 = 17π/60
area of sector= 1/2 × r²× ∅
= 1/2 × 2²× 17π/60
= 34π/60
= 1.78m²
The equation becomes y =-0.7x²+5.4x+6 if the person who is 6 feet tall throws a ball into the air option first is correct.
<h3>What is a quadratic equation ?</h3>
Any equation of the form
Where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
The standard form of a quadratic equation:

Plug x = 0 and y = 6
6 = c ...(1)
Plug x = 1, and y = 10.7
10.7 = a + b + c ...(2)
Plug x = 2 and y = 14
14 = 4a + 2b + c ...(3)
After solving equation (1), (2) and (3) we get:
a = -0.7
b = 5.4
c = 6

Thus, the equation becomes y =-0.7x²+5.4x+6 if the person who is 6 feet tall throws a ball into the air option first is correct.
