Line k passes through points (-3,-6) and (-1,12) what is the slope of the line perpendicular to line c

1 answer:

4 0

Do you mean "perpendicular to k"? We have no line c there so I'm going with line k. First we need the slope of line k. Fitting those values into the slope formula we have $m= \frac{12-(-6)}{-1-(-3)} = \frac{18}{2} =9$ . So the slope of k is 9. The slope of a line perpendicular to k has the opposite sign and the fraction is flipped. The perpendicular slope then is -1/9.

A perfect square is the square of an integer. Of the integers from 2 through 99, how many have at least one perfect square facto

Answer:

Six numbers have perfect square factors

Step-by-step explanation:

The numbers with perfect square factors are those numbers that have perfect squares as one of the numbers that can divide them.

They include:

4 = 2 * 2

16 = 4 * 4

36 = 6 * 6

49 = 7 * 7

64 = 8 * 8

81 = 9* 9

These numbers above have perfect square factors because they are formed from integers that multiply themselves.

⇒ f(2) = 3(2) + 1

⇒ f(2) = 6 + 1 = 7

BRAINLIEST TO FIRST CORRECT ANSWER!!

sineoko [7]

Answer:

$57\:\mathrm{km}$

Step-by-step explanation:

Since the question implies his truck travels at a constant distance per gallon, we can set up the following proportion to find how much father his truck can go.

Let $x$ represent how much farther his truck can go, in kilometers:

$\frac{2}{76}=\frac{1.5}{x}$

Cross-multiplying, we get:

$2x=76\cdot 1.5,\\x=\frac{76\cdot 1.5}{2}=\boxed{57\:\mathrm{km}}$
