Answer:
Step-by-step explanation:
You would use the equation, 
r= radius, n = number of sides
Answer:
X=5,-2
Steps:
Get everything to the same side:
X^2-3x-10=0
Then factor:
(X-5)(x+2)=0

Step-by-step explanation:
400 and 40
400 ÷ 40 = 10
Answer:
19.5 yd
Step-by-step explanation:
To khown the maximum height we must derivate the function and see when the derivated function equals 0
Let f be our function : f(x)= -0.04x²+1.56x ⇒f'(x)= -0.08x+1.56
- f'(x)= 0 ⇒ -0.08x+1.56 =0 ⇒1.56= 0.08 ⇒ x= 1.56/0.08 ⇒ x=19.5
- so the maximum height is 19.5 yd
Use PEMDAS:
P Parentheses first
E Exponents (ie Powers and Square Roots, etc.)
MD Multiplication and Division (left-to-right)
AS Addition and Subtraction (left-to-right)
[(30 + 6) - 32] : 9 · 2 = (36 - 32) : 9 · 2 = 4 : 9 · 2 = 4/9 · 2 = 8/9
