Answer:
Step-by-step explanation:
Find the y-intercept by setting x = 0: f(0) = 3(4)^0 = 3(1) = 3 => (0, 3)
4^x is never zero, and its graph is always above the y-axis, for both positive and negative x.
Any real number is an acceptable x-value.
Thus the domain is (- infinity, infinity) and the range is (0, infinity).
Answer:
30 bucks per square foot
Step-by-step explanation:
8.2x-2.1x=183
is the equation.
6 ft person casts 18 ft shadow
x ft tree casts 20 ft shadow
6*20 = 18x
120 =18x
x=120/18
×≈6.67
Answer:
x = 12
Step-by-step explanation:
3 (x-5) = 2x - 3
3x -15 = 2x - 3
x-15 = -3
x = 12

21 = 21
The law of conservation of energy. The energy due to work performed on the skateboarder is converted into kinetic energy such that:
Work=Kinetic Energy
So 380=(1/2)(35)(7-Vo). I don’t have a calculator so..
Assumptions we made:
No energy loss, all work went into the energy of motion of the skateboarder. In the real world, this is not possible because some of the energy can be loss through friction of the skateboarder to the ground etc.
