The height of a ball dropped from the top of a 450-foot tall building can be described by the expression
BaLLatris [955]

Answer:

The answer is 386 feet.

Step-by-step explanation:

This equation simply asks to plug in a value that gives you the final value of the height. 450 is the initial height, and r (or l) is referred to as the amount of seconds after the item is dropped. 16 is the constant value of feet that the ball drops within one second.

Therefore, by substituting 4 for r (or l) and multiplying it by 16, you will receive 64 feet in 4 seconds. Finally, you need to subtract this from 450 feet, giving you a final answer of 386 feet.

Svetllana [295]
The answer is -20x, because the parentheses show they are being multiplied, so you multiply -10x and 2, which would be -20x.

Hurry please !!!
Firdavs [7]

Answer:

The translation corresponds to : g(x)=\sqrt[3]{x-4}

which is the first option in your list of possible answers

Step-by-step explanation:

Notice that this new function's graph responds to a horizontal translation to the right of the original graph of f(x)=\sqrt[3]{x}. Notice that the crossing of the x-axis, which for f(x) is at the origin (0, 0), has now moved to the point (4,0), which means a translation to the right in exactly 4 units.

Recall that horizontal translations are performed by subtracting from the independent variable  (x) , the number of units you move (in this case 4)

Therefore the new function should look like:

g(x)=\sqrt[3]{x-4}
