Find the value of x<br> A.25<br> B.85<br> C.75<br> D.105

Masteriza [31]

Answer:

The value of x is 75

Step-by-step explanation:

First we need to find the other angle that doesn't have a number in it.

To find the degrees of the other angle we subtract 155 from 180.

180 - 155 = 25

Now we have to find the value of x. Add 80 and 25 together to get 105. A triangle is going to be 180 degrees. Subtract 105 from 180.

180 - 105 = 75

Now we will add 80, 25, and 75 to check our work.

80+25+75 = 180

A particle moves along a line with acceleration a (t) = -1/(t+2)2 ft/sec2. Find the distance traveled by the particle during the

amm1812

Answer:

$s(t)=(ln|7|+ln|2|)\,ft$

Step-by-step explanation:

Acceleration is second derivative of distance and are related as:

$a(t)=\frac{d^2s}{dt^2}\\\\\frac{d^2s}{dt^2}=\frac{-1}{(t+2)^2}\\$

Integrating both sides w.r.to t

$v(t)=\frac{ds}{dt}=\frac{1}{t+2} +C\\$

Using initial value

$v(0)=\frac{1}{2}\\\\\frac{1}{2}=\frac{1}{0+2} +C\\\\C=0\\\\\frac{ds}{dt}=\frac{1}{t+2}$

We have to calculate the distance covered in time interval [0,5], so:

$\int\limits^5_0 \frac{ds}{dt}=\int\limits^5_0 {\frac{1}{t+2}} \, dt\\\\s(t)=[ln|t+2|]^5_0\\\\s(t)=ln|5+2|+ln|0+2|\\\\s(t)=(ln|7|+ln|2|)\,ft$

DIRECTIONS: Use this information to answer Parts A, B, and C.

Talja [164]

Answer:

V=706.85

Step-by-step explanation:

Well, first of when you want to find the volume of the cone you need to have a radius and hieght. And the radius is half the diameter, so divide the diameter into half: 10/2=5 in. and you already have the height so just plug in the numbers.

Formula: V= $\frac{1}{3}$ $\pi$ $r^{2}$ h ---> V= $\frac{1}{3}$ $\pi$ ( $5^{2}$ )(27)

And put the plugged in formula in your calculator and you'll find the answer!

V=706.85

I hope this helped.

eimsori [14]

Well taking off the tax brings the total to $80. Divide that by the ten reams of paper will give you $8 per ream.
