Answer:
80 km
Step-by-step explanation:
First, find the perimeter of the park.
2(12 + 8) = 2(20) = 40 km
Since Rama travels around the park twice, multiply the perimeter by 2.
40(2) = 80 km
A=1/2 b*h
So substitute it in 1/2*1/2*4
1/2*1/2= 1/4
1/4*4= 4/4= 1 so the entrance is 1 foot tall
I will do the first one only. The second question is done the same way.
Replace every x you see in the function with 2b and do the math.
f(x) = x^2 + 2x + 1
Let x = 2b
f(2b) = (2b)^2 + 2(2b) + 1
f(2b) = 4b^2 + 4b + 1
Did you follow? That's all there is to it.
Answer:
E
Step-by-step explanation:
The parent function y = | x | has it's vertex at the origin
Here the vertex is at (- 4, 2)
That is shifted 4 units to the eft of the origin, thus
y = | x + 4 |
Shifted 2 units up is denoted by + 2, thus
y = | x + 4 | + 2 → E
