Steps to solve:

z + z + z when z = -4

~Substitute

-4 + (-4) + (-4)

~Simplify

-4 - 4 - 4

~Subtract

-8 - 4

~Subtract

PLZ HELP ME ASAP<br> algebra 2 word problem
Ostrovityanka [42]

Give each month a number:

January = 0

February = 1

March = 2

April = 3

Now set X to 3 in the equation ad solve for t.

t = -30cos(x/6) +60

t = -30cos(3/6) +60

t = 33.672 degrees. ( Round as necessary)

You would need to change the +60 to a new starting point based on what the rise in temperature is due to global warming.

The profits in hundreds of dollars, P(c), that a company can make from a product is modeled by a function of the price, c, they
Jobisdone [24]
The maximum profit is the y-coordinate of the vertex of the parabola represented by the equation.

P(c)=-20c^2+320c+5120 \\ \\&#10;a=-20 \\&#10;b=320 \\ \\&#10;\hbox{the vertex } (h,k): \\&#10;h=\frac{-b}{2a}=\frac{-320}{2 \times (-20)}=\frac{-320}{-40}=8 \\&#10;k=f(h)=f(8)=-20 \times 8^2+320 \times 8+5120= \\&#10;=-1280+2560+5120=6400

The maximum value is 6400, but the profit is given in hundreds of dollars, so multiply the value by 100.

The maximum profit the company can make is $640,000.

How can you use a right angle to dicide how to name another angle?
DanielleElmas [232]
If it is a square, subtract (90+ whatever the other angle is) from 360. If it is a triangle than add 90 plus whatever other number the other angle is then subtract it from 180. A triangle is 180 degrees, and a square is 360 degrees.

A random variable X follows the uniform distribution with a lower limit of 670 and an upper limit of 750.a. Calculate the mean a
DENIUS [597]

You can compute both the mean and second moment directly using the density function; in this case, it's

f_X(x)=\begin{cases}\frac1{750-670}=\frac1{80}&\text{for }670\le x\le750\\0&\text{otherwise}\end{cases}

Then the mean (first moment) is

E[X]=\displaystyle\int_{-\infty}^\infty x\,f_X(x)\,\mathrm dx=\frac1{80}\int_{670}^{750}x\,\mathrm dx=710

and the second moment is

E[X^2]=\displaystyle\int_{-\infty}^\infty x^2\,f_X(x)\,\mathrm dx=\frac1{80}\int_{670}^{750}x^2\,\mathrm dx=\frac{1,513,900}3

The second moment is useful in finding the variance, which is given by

V[X]=E[(X-E[X])^2]=E[X^2]-E[X]^2=\dfrac{1,513,900}3-710^2=\dfrac{1600}3

You get the standard deviation by taking the square root of the variance, and so

\sqrt{V[X]}=\sqrt{\dfrac{1600}3}\approx23.09
