Ethan rollerbladed a total of 623 \text{ km}623 km623, start text, space, k, m, end text over ddd days. He rollerbladed the same
Sever21 [200]

Answer:

Ethan rollerbladed each day  \frac{623}{d}  kilometers.

Step-by-step explanation:

Given:

Ethan rollerbladed a total of 623 km over d days.

Now, to find the kilometers Ethan rollerblade each day.

Total number of distance rollerbladed = 623 km.

Total number of days = d.

<u><em>As, Ethan rollerbladed each day the same distance.</em></u>

Now, to get the distance Ethan rollerbladed in each day we divide total number of distance rollerbladed by total number of days:

Ethan\ rollerbladed\ each\ day\ =\ \frac{Total\ number\ of\ distance\ rollerbladed}{Total\ number\ of\ days}

Ethan\ rollerbladed\ each\ day\ =\ \frac{623}{d}

Therefore, Ethan rollerbladed each day \frac{623}{d}  kilometers.

Store display volume of each cube shaped box is 125 cubic inches of the display has six layers of boxes how high is the display
Doss [256]

Answer:

30 inches

Step-by-step explanation:

We know that the formula for calculate the volume of a cube is:

∨=8³

Where "s" is the length of each side.

Since the volume of each cube-shaped box is 125 cubic inches, we can find "s":

125 in³=8³

∛125 in³=8

8=5 in

We know that  the display has six layers of boxes, then , to calculate the height of the display, we can multiply the value of "s" obtained before by 6.

Then:

height= (5 in)(6)=30 in

Find 2x2 - 2z4 + y2 - x2 + z4 if x = -4, y = 3, and z = 2.
Alexxandr [17]
X = - 4;  y = 3;  z = 2;
2 x² - 2 z^4 + y² - x² + z^4 =
= 2 * (-4)² - 2 * 2^4 + 3² - ( -4)² + 2^4 =
= 2 * 16 - 2 * 16 + 9 - 16 + 16 =
= 32 - 32 + 9 - 16 + 16 =  9

Please help!!!!
koban [17]

Answer:

Correct choice is A

Step-by-step explanation:

If a function has an inverse, then there is at most one x-value for each y-value.

The tangent function is periodic with period \pi. Hence, at each value for which f(x)=\tan x is defined, f(x+n\pi )=\tan x for each integer n. Therefore, the function f(x)=\tan x does not have an inverse. Since tangent is not a one-to-one function, the domain must be limited. From examining the graph of the tangent function, we see that in each interval of the form

\left((2k−1)\dfrac{\pi}{2},(2k+1)\dfrac{\pi}{2}\right)

where k is an integer, the tangent function assumes every value in its range. Moreover, in each such interval, each y-value is achieved exactly once. Hence, we can create an invertible function by restricting the domain tangent function to one such interval. Such interval is an interval between two consecutive vertical asymptotes x=(2k−1)\dfrac{\pi}{2} and x=(2k+1)\dfrac{\pi}{2}.
