Need help with finding perpendicular line that goes through (4,5)

First divide each side by 2 isolate y. Now you have y = (-9/2)x - 12. The slope is (-9/2). For a perpendicular line, flip the slope and negate it to get 2/9. Then use y = mx + b.

5 = (2/9)(4) + b
5 = (8/9) + b
(37/9) = b

So the equation is y = (2/9)x + 37/9 or
9y = 2x + 37.

I really really need help!!!!!!

Svetllana [295]

ANSWER

$y = 5 \sin( \frac{6}{5} x - \pi)-4$

EXPLANATION

The given function is

$y = 5 \cos( \frac{3}{5} x - \pi) + 4$

The period of this function can be determined using the formula:

$T= \frac{2\pi}{ |b| }$

.

The period is

$T= \frac{2\pi}{ \frac{3}{5} } = \frac{10\pi}{3}$

Half the period of this function is:

$\frac{ \frac{10\pi}{3} }{2} = \frac{5\pi}{3}$

The function which has this period is

$y = 5 \sin( \frac{6}{5} x - \pi) -4$

The first choice is correct.

find the mean of the following group of numbers: 6.1, 5.9, 4.2, 5.9, and 10.7. round your answer to the nearest tenth. responses

The mean of the given set of group numbers is 6.6

Given,

In the question:

The Group of numbers are as follows:

6.1, 5.9, 4.2, 5.9 and 10.7

To find the mean of the given set of group of numbers.

Now, According to the question:

Given is the following data:

6.1, 5.9, 4.2, 5.9 and 10.7

We can find the mean of the given set of data using the formula-

Mean (M) = Σ a[i]/n = (Sum of all the elements)/(total number of elements)

Now, n = 5

and Σ a[i] = 6.1 + 5.9 + 4.2+ 5.9 + 10.7 = 32.8

Putting the values in the formula, we get:

M = 32.8/5 = 6.56 = 6.6

Hence, The mean of the given set of group numbers is 6.6
