The space shuttle can travel at 28968 km/h what distance can it cover in 8 hrs?
Verdich [7]

Given:

A space shuttle can travel at 28968 km/h.

To find:

The distance it can cover in 8 hrs.

Solution:

We have,

Speed of space shuttle = 28968 km/h.

So,

Distance covered by the space shuttle in 1 hour = 28968 km/h.

Distance covered by the space shuttle in 8 hour = (28968 × 8) km

                                                                                 = 231744 km

Therefore, the distance it can cover in 8 hrs is 231744 km.

Two negative integers are 5 units apart on the number line, and their product is 126. What is the sum of the two integers?
Tatiana [17]
If b>a, b-a=5 so b=5+a

ab=126, using b from above

a(5+a)=126

5a+a^2=126

a^2+5a-126=0
 
(a+14)(a-9)=0, since a<0 the numbers are

-14 and -9

What is the rate of change of y with respect to x for this function?
loris [4]

bearing in mind that the average rate of change = slope, and for that we can simply use two points off the table.

\bf \begin{array}{|cc|ll} \cline{1-2} x&y\\ \cline{1-2} -2&12\\ 0&3\\ 3&-10.5\\ 7&-28.5\\ \cline{1-2} \end{array}\qquad \qquad \begin{array}{llll} (\stackrel{x_1}{-2}~,~\stackrel{y_1}{12})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{-10.5}) \\\\\\ slope \implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-10.5-12}{3-(-2)} \\\\\\ \cfrac{-10.5-12}{3+2}\implies \cfrac{-22.5}{5}\implies -\cfrac{4.5}{1}\implies -4.5 \end{array}
