Answer:

x^2 +2x -15

Step-by-step explanation:

FOIL

(x-3)(x+5)

first x*x = x^2

outer 5x

inner -3x

last -3*5 = -15

Add them together

x^2 +5x-3x-15

Combine like terms

x^2 +2x -15

Find an equation of the line that satisfies the given conditions.

Makovka662 [10]

Well, the very first thing you need to do is to <span> find the slope of the line
According to the fact that we already know that the slope is parallel </span>to the line, you can easily find out the slope, to be more exact : $m=(Y2-Y1)/X2-X1)=4/4=1$
Straight after, you have to use <span>point slope formula</span> $Y-Y1=m(X-X1)

Y-7=X-6$

A rectangular prism has a width of 16 inches and a length of 10 inches. The volume of the rectangular prism is decreasing at a r

frosja888 [35]

Answer:

-3.47 inches per minute

Step-by-step explanation:

Let the height be 'h' for any time 't'.

Given:

Length of the prism (L) = 10 in

Width of the prism (w) = 16 in

The rate of change of volume of prism is, $\frac{dV}{dt}=-555\ in^3/min$ (The negative sign implies the volume decreases with time.)

Now, rate of change of height of prism = $\frac{dh}{dt}=?$

Length and width remains constant.

Now, we know that, volume of a rectangular prism is given as:

Volume = Length × width × Height

$V=Lwh\\\\V=10\times 16\times h\\\\V=160h$

Now, differentiating both sides with respect to time 't', we get:

$\frac{dV}{dt}=\frac{d}{dt}(160h)$

Plug in the given values and solve for $\frac{dh}{dt}$ . This gives,

$-555=160\times \frac{dh}{dt}\\\\\frac{dh}{dt}=\frac{-555}{160}\\\\\frac{dh}{dt}=-3.47\ in/min$

The negative sign implies the height decreases with time.

Therefore, the the rate of change, in inches per minute, of the height when the height is 3 inches is -3.47 inches per minute.
