A cell phone company charges $60 for a cell phone and a monthly rate to use the phone regina will pay $1140 for a 24 month cell

vitfil [10]

Answer: the monthly rate for the cell phone plan is $45

Step-by-step explanation:

Let m represent the monthly rate that the cellphone company charges.

A cell phone company charges $60 for a cell phone and a monthly rate to use the phone. This means that the total charge for using the phone for x months would be

60 + xm

If Regina will pay $1140 for a 24 month cell phone plan, it means that

1140 = 60 + 24m

24m = 1140 - 60

24m = 1080

m = 1080/24 = 45

Which of the following are the appropriate LaTeX: f\left(x\right)f ( x ) and LaTeX: g\left(x\right)g ( x ), for LaTeX: H\left(x\

katen-ka-za [31]

Answer:

$f\left(x\right)=\cos\left(x\right)\: and\:\: g\left(x\right)=\left(2x^2-1\right)$

Step-by-step explanation:

We have, $H\left(x\right)=\cos\left(2x^2-1\right)H ( x )$

$=\cos\left(2x^2-1\right)$

And $H\left(x\right)=\left(f\:\circ\:g\right)\left(x\right)H ( x ) = \left(f\:\circ\:g\right)( x )$

$\Rightarrow \left(f\:\circ\:g\right)(x)=\cos\left(2x^2-1\right)$

Now, $f\left(x\right)=\cos\left(x\right)$ and $g\left(x\right)=\left(2x^2-1\right)$

A triangular plot of land has one side along a straight road measuring 147147 feet. A second side makes a 2323degrees° angle wit

ch4aika [34]

Answer:

81.23 ft and 77.88 ft long

Step-by-step explanation:

The sum of the internal angles of a triangle is 180 degrees, the missing angle is:

$a+b+c=180\\a+23+22=180\\a=135^o$

According to the Law of Sines:

$\frac{A}{sin(a)}= \frac{B}{sin(b)}= \frac{C}{sin(c)}$

Let A be the side that is 147 feet long, the length of the other two sides are:

$\frac{A}{sin(a)}= \frac{B}{sin(b)}\\B=\frac{sin(23)*147}{sin(135)}\\B=81.23\ ft\\\\\frac{A}{sin(a)}= \frac{C}{sin(c)}\\C=\frac{sin(22)*147}{sin(135)}\\C=77.88\ ft$

The other two sides are 81.23 ft and 77.88 ft long
