How can exponents help you find the area of a rectangle if each side length is multiplied by x?

1 answer:

4 0

Exponents can make the problem smaller and look less confusing. If you see a problem with 5*5*5*5*5*5*5*5 then you're going to eventually loose count and will have to keep repeating. But if you put 5 to the 8th power then you know right away just to multiply 5, (8) times,

A set of data already has the values 11, 14, 23, and 16. What value would have to be added to the set for the mean of the five n

KonstantinChe [14]

1) Take 18 and multiply it by 5 = 90
2) Then subtract 26 = 64
3) Then subtract 18 = 46
4) Then subtract 12 = 34
5) Then subtract 8 = 26

The answer is 26.

Can someone please explain how to get this answer? Recursive formula help! t(1)=3 (in picture)

kipiarov [429]

T(1) = 3, t(n) = -2t(n-1) + 1
So t(2) = -2(t(1)) + 1 = -2(3) + 1 = -5
t(3) = -2(t(2)) +1 = -2(-5) +1 = 11
t(4) = -2(t(3)) +1 = -2(11) +1 = -21
t(5) = -2(t(4)) +1 = -2(-21) +1 = 43

For what x-value(s) does cos(x) = 1? -360° 0° 360° all of the above

dlinn [17]

Cos(x) = 1 at 0 and 2pi 360 and -360 is the same angle as 2pi so all of the above if you start at 0 and make a complete circle (360) you will be back at point 0.

Findthe

Elanso [62]

Answer:

y- intercept = - 6

Step-by-step explanation:

The y- intercept is where the graph crosses the y- axis.

Let x = 0 and substitute in to the equation, that is

y = 0² - 3(0) - 6 = 0 - 0 - 6 = - 6 ← y- intercept
