Answer:
59 yards x 99 yards
Step-by-step explanation:
Soccer fields are rectangular. If the width is W and the length is L:
316 = 2W + 2L
5841 = WL
We have two equations and two variables. Start by solving for one of the variables in the first equation:
316 = 2W + 2L
158 = W + L
W = 158 − L
Substitute into the second equation
5841 = (158 − L) L
5841 = 158 L − L²
L² − 158 L + 5841 = 0
Factor (or use quadratic formula):
(L − 59) (L − 99) = 0
L = 59 or 99
Find W:
W = 99 or 59
Therefore, the dimensions of the soccer field are 59 yards by 99 yards.
Answer:
Step-by-step explanation:
Given the function
f(x) = 2x³ -3x²+ 7
putting x=-1 to find f(-1)
f(-1) = 2(-1)³ -3(-1)²+ 7
= -2 + 3 + 7
= 8
putting x=1 to find f(1)
f(1) = 2(1)³ -3(1)²+ 7
= 2 - 3 + 7
= 6
putting x=2 to find f(2)
f(2) = 2(2)³ -3(2)²+ 7
= 16 - 12 + 7
= 11
Therefore,
Normally, I'd give the function a name. Commonly we see "f(x)," which means "f is a function of x." We'd follow that with an " = " sign.
