Answer:
0 (zero)
Step-by-step explanation:
Plug in the variable for -4 and solve
y= 2(-4)2-4(-4)
y= -8(2)-4(-4)
y=-16+16
y=0
Answer: -1
Step-by-step explanation:
1-(-1^2)+(-1^3) = 1-1+(-1)= -1
Answer:
154 ft
Step-by-step explanation:
A right triangle is formed, where the height of the wheel (h) is one leg, the distance between you and the base of the wheel is the other leg, and the distance between you and the top of the wheel is the hypotenuse (the angle included between the last two sides is 51°)
From definition:
tan(51°) = opposite/adjacent
tan(51°) = h/125
h = tan(51°)*125
h = 154 ft
Answer:
Option (b) is correct.
Step-by-step explanation:
Given: 
We have too choose the correct simplification for the given statement.
Consider
Using property of exponents, 
We have,
Again applying property of exponents 
We have,
Simplify, we have,
we get,
Thus, 
Option (b) is correct.
