Answer: -2/7
This value is a fraction.

----------------------------------

Work Shown:

The first two rows in the table produce these two points (x1,y1) = (-14,8) and (x2,y2) = (-7,6)

So, x1=-14, y1=8, x2=-7, and y2=6

Plug these four values into the slope formula and simplify
m = (y2 - y1)/(x2 - x1)
m = (6 - 8)/(-7 - (-14))
m = (6 - 8)/(-7 + 14)
m = -2/7

A window shaped like a parallelogram has an area of 30 square feet. The height of the window is 4

Viefleur [7K]

Answer:

The base of the window is 7.5 feet long.

Step-by-step explanation:

The area of a parallelogram can be found with the formula A = bh

Plug in the known values to get 30 = 4b

30 = 4b

30/4 = b

7.5 = b

The square root of a number is between 18 and 19

astraxan [27]

Then the number must be between 18² = 324 and 19² = 361. But is that what you want to know?

Suppose the position of an object moving in a straight line is given by s (t )equals 4 t2+ 5 t+ 5. Find the instantaneous veloci

VLD [36.1K]

Answer:

$v(t) = 8t +5$

And that represent the instantaneous velocity at a given time t.

And then we just need to replace t =2 in order to find the instantaneous velocity and we got:

$v(t=2) = 8*2 + 5 = 16+5 = 21$

Step-by-step explanation:

For this case we have the position function s(t) given by:

$s(t) = 4t^2 + 5t+5$

And we can calculate the instanteneous velocity with the first derivate respect to the time, like this:

$v(t) = s'(t)= \frac{ds}{dt}$

And if we take the derivate we got:

$v(t) = 8t +5$

And that represent the instantaneous velocity at a given time t.

And then we just need to replace t =2 in order to find the instantaneous velocity and we got:

$v(t=2) = 8*2 + 5 = 16+5 = 21$
