Find the g(x) points by plugging in the values of x into 2(x + 3)^2 - 1
so for x - -3 g(x) = 3(-3+3)^2 - 1 = 3(0)^2 - 1 = 0 - 1 = -1
calculate the other values of x -2 , -1 , 0 and 1 in the same way
Answer:
X=10
Step-by-step explanation:
Cos30 = sin(90 - 60) = √3/2, because cos and sin are complements
cos120 = cos(180 - 60) = -cos60 = -1/2
If the pond were a rectangle, then:
length=15 m
width=6 m
We would have to calculate the perimeter of this rectangle.
Perimeter of a rectangle=2(length)+2(width)
Perimeter of this rectangle=2(15 m)+2(6 m)=30 m+12 m=42 m
We need 42 m and I only have 40 m, therefore, it would not be enough for fencing the pond.
I’m pretty sure the answer is C
