The equation is y = 14x + 10.<br><br> Which is true regarding the slope?
rjkz [21]

Answer:

The slope is 14/1, meaning you rise 14, then run 1. This is a steep slope.

Step-by-step explanation:

The slope equation is y=mx+b. The "m" in the equation is equal to the slope. In your case, 14 takes the place of the "m", making it the slope.

Solve the following equation for x. Round the answer to the nearest hundredth.
Serhud [2]

Hence, option D 4: x=-1.34 is correct

Further explanation:

In order to solve an equation in one varible we have to isolate the variable on one side of the equations

Given equation is:

-1.2x=2(x+2.15)\\Simplifying\\-1.2x=2x+4.3\\Subtracting\ 2x\ from\ both\ sides\\-1.2x-2x=2x+4.3-2x\\-3.2x=4.3\\Dividing\ both\ sides\ by\ -3.2\\\frac{-3.2x}{-3.2}=\frac{4.3}{-3.2}\\x=-1.34375\\Rounding\ off\ to\ nearest\ 100th\\x=-1.34

Hence, option D: x=-1.34 is correct

The formula for the volume of a sphere is S = 4 3 πr3, where r (in feet) is the radius of the sphere. Suppose a spherical snowba
Soloha48 [4]

Answer with Step-by-step explanation:

We are given that

Volume of sphere=\frac{4}{3}\pi r^3

Where r= Radius of sphere in ft

a.r=\frac{1}{(t+1)^2}-\frac{1}{15}

\frac{dr}{dt}=\frac{-2}{(1+t)^3}

\frac{dS}{dt}=\frac{dS}{dr}\cdot \frac{dr}{dt}=4\pi r^2\frac{dr}{dt}

\frac{dS}{dt}=4\pi(\frac{1}{(1+t)^2}-\frac{1}{15})^2\times \frac{-2}{(1+t)^3}

\frac{dS}{dt}=\frac{-8\pi}{(1+t)^3}(\frac{1}{(1+t)^2}-\frac{1}{15})^2

b.Substitute t=1

Then, we get

\frac{dS}{dt}=\frac{-8\pi}{8}(\frac{1}{4}-\frac{1}{15})^2

\frac{dS}{dt}=-0.1056 ft^3/min
