Minus 180 from 190. You have -10
2x= -10
Which means x equals -5

That's correct. Now you gotta plug in -5 in for x and get both angles.

Answer: first option

Step-by-step explanation:

The volume of a regular pyramid can be calculated with the following fromula:

$V=\frac{B*h}{3}$

Where B is the area of the base of the pyramid and h iis the height of the pyramid.

The base is a square, therefore, its area B is:

$B=side^2\\B=(2units)^2\\B=4units$

You know that the height is 3, therefore, you can substitute these values into the formula.

THerefore, the volume of the pyramid is:

$V=\frac{4units^2*3units}{3}$

$V=4units^3$

Use partial fraction expansion to evaluate: LaTeX: \int\frac{x-1}{x^2+3x+2}dx ∫ x − 1 x 2 + 3 x + 2 d x a. LaTeX: -2\ln\left|x+1

ohaa [14]

$\frac{x-1}{x^2+3x+2}\\\frac{x-1}{(x+1)(x+2)}\\\frac{x-1}{(x+1)(x+2)}=\frac{A}{x+2}+\frac{B}{x+1}\\x-1=A(x+1)+B(x+2)\\\\\text{ Let } x=-1 \text{ then } -2=A(0)+B(-1+2) \text{ which means } B=-2\\\\\text{ Instead of choose } x \text{ to be -1, let's now set it equal to -2 to find } A\\\\-3=A(-1)+B(-2+2)\\-3=-A\\A=3\\\\ \text{ So your integral becomes } \\\int \frac{3}{x+2} dx+\int \frac{-2}{x+1} dx\\3 \ln|x+2|-2\ln|x+1|+C\\\\or\\-2\ln|x+1|+3\ln|x+2|+C$

From a shipment of 400 light-bulbs, a sample of 80 was selected at random and tested. If 32 light-bulbs in the sample were found

denis-greek [22]

80 x 5 = 400
32 x 5 = 160
so you have about 160 <span>defective bulbs</span>
