Line n passes through points (7, 12) and (4, 15). What is the slope of a line that

vitfil [10]

So anytime we have a slope and want to find the slope of a perpendicular line, we just have to remember a perpendicular line's slope is the negative reciprocal (reciprocal means flip the fraction). So if we had a slope of 3/4, the slope perpendicular to it would be - 4/3.

First we need to find our slope, to do this we take the change in y over the change in x like so:

(15-12)/(4-7) = - 3/4

The slope perpendicular to this is 4/3.

The function below models the voltage, in volts, of a certain alternating current after x seconds, where A and b are positive co

Katarina [22]

First of all, we can just ignore A, it has no effect but to vertically stretch our cosine.

If it was only $f(x)=cosx$ , the function would be invertible as long as it's confined between $0$ and $\pi$ . Now, the argument of our cosine is not $x$ but $bx$ . It means that it won't stop at $\pi$ , but at $\frac{\pi}{b}$ .

Another way to think about it, "what should i replace x with so I get $\pi$ inside the cosine?"

Leya [2.2K]

all the coordinates of the original triangle have been multiplied by 1/2

A (-4,-6) x 1/2 = -2,-3

B (-8,2) * 1/2 = -4,1

C (-2,4) *1/2 = -1,2

so the scale factor is 1/2

Answer is B

Find the sum of polynomials (30 points!!)

hammer [34]

Answer:

2nd option

Step-by-step explanation:

Express the sum of the 2 polynomials by removing the parenthesis , so

5 $x^{5}$ - 2x³ + x + 4 $x^{5}$ - 3 $x^{4}$ + 2x³ - 5x ← collect like terms

= 9 $x^{5}$ - 3 $x^{4}$ - 4x
