Answer:

when x = 1 then y = 9

when x = -20 then y = -33

when x = 43 then y = 93

Step-by-step explanation:

Just replace the given values of x ( which are 1 , -20 , 43 ) in the function

Find the measure of an exterior angle of each regular polygon: 100-gon.

Gelneren [198K]

If this is a 100-gon, then not only does it have 100 sides, it also has 100 central angles. Each one measures 360/100 = 3.6. This is the vertex angle for each of those 100 triangles. 180 - 3.6 = 176.4, which has to be split equally between the 2 base angles. This puts each of those at 88.2. If you are looking for the exterior angle to each of those, it's the supplement of them. 180-88.2 = 91.8

Simplify.

Nitella [24]

Answer:

I hope this is the whole question

Step-by-step explanation:

Well I can only see one way and it is this...

$\sqrt{27a}$ = $\sqrt{3.3.3.a}$

= $3\sqrt{3a}$

I got rid of one perfect-square. I dont think you can do much more.

SPIDER ~ HNYCMB<br> Find NY, YC, CM, AND MB.

zzz [600]

Answer:

HN = 66, NY = 27, YC = 30, CM = 27, MB = 42,

Step-by-step explanation:

When comparing the two shapes, SPIDER is 0.75 times larger than HNYCMB. Besides this small detail they are the same shape. We can determine this by identifying which sides are most similar and dividing them, if SP "=" HN, then to find the rate at which figure HNYCMB shrank is to divide SP by HN. 66/88 is 0.75. By multipying the sides of figure SPIDER by 0.75, we get our answers.

HN ~ SP, 66 = 88 * 0.75, HN = 66

NY ~ SR, 27 = 36 * 0.75, NY = 27

YC ~ RE, 30 = 40 * 0.75, YC = 30

CM ~ ED, 27 = 36 * 0.75, CM = 27

MB ~ DI, 42 = 56 * 0.75, MB = 42

BH ~ PI, BH = ? Try this one by yourself for understanding
