- Olivia skates twice as far as Stephanie. This sum of their distances is 96 miles per month. How many

kotegsom [21]

Answer:

B.64 miles

Step-by-step explanation:

Let Oliver's be x

Let Stephanie's be y

$x = 2y - - - (a) \\ x + y = 96 - - - (b)$

substitute for x in (b):

$2y + y = 96 \\ 3y = 96 \\ y = 32$

find x in (a):

$x = (2 \times 32) \\ x = 64$

So hmmm notice the picture below

thus $\bf \textit{volume of a rectangular prism}\\\\
V=lwh\qquad 
\begin{cases}
l=length\\
w=width\\
h=height\\
----------\\
l=100\\
w=20\\
V=225,000
\end{cases}\implies 225,000=(100)(20)h$

solve for "h"

When an object is thrown upwards with a speed of 64 ft/sec, its height above the ground is given by the function h(t)=−16t2+64t

Svet_ta [14]

Answer:

The object will reach its highest point 0.5 seconds after it has been thrown.

Step-by-step explanation:

The object reaches its maximum height when velocity is equal to zero, the velocity is the derivative of function height. That is:

$v(t) = \frac{d}{dt}h(t)$ (1)

Where $v(t)$ is the velocity of the object at time $t$ , in feet per seconds.

If we know that $h(t) =-16\cdot t^{2}+64\cdot t$ and $v(t) = 0\,\frac{ft}{s}$ , then the time when object reaches its highest point is:

$v(t) = -32\cdot t+64$

$-32\cdot t + 64 = 0$

$t = 0.5\,s$

The object will reach its highest point 0.5 seconds after it has been thrown.
