Any number raised to power of 0 is 1.
In (-4x)^0, because of the parenthesis, the whole number is being raided to 0, which gives 1.
But in -4x^0, only x is being raised to 0, thus -4x^0 = -4(1) = -4.
Answer:
$1 every 3 minutes

Answer:
80.5°
Step-by-step explanation:
The applicable trig function is the tangent.
Tan = Opposite/Adjacent
In this scenario, the side opposite the angle is the tower height, 324 m. The side adjacent is the distance to the tower, 54 m. Then the angle α is related by ...
tan(α) = 324/54
The value of the angle with this tangent is found using the arctangent function:
α = arctan(324/54) ≈ 80.5°
She should set her binoculars to 80.5°.
Answer:
f(x) = 0.2x
Step-by-step explanation:
hello :
let : f(x) = ax+b calculate a and b
f(x-3) =a(x-3)+b = ax+b-3a.....(*)
given : f(x-3) = 0.2x-0.6...(**)
by (*) and(**) : a= 0.2 and b-3a = - 0.6
b-3(0.2) = - 0.6
so : b=0
conclusion : f(x) = 0.2x
