Raise 8 to the 5th power, then subtract the result from h. What would the expression be?
lawyer [7]
The equation would look like this:

h - 8⁵

To solve for the value of h.
It must be in standard form, where one side is equal to 0.

h - 8⁵ = 0
h = 8⁵
h = 8 x 8 x 8 x 8 x 8
h = 32,768

T
he exponent above the number indicates the number of time its base will be multiplied by itself. In this case, the base will be multiplied 5 times.

To check: h = 32,768
h - 8⁵ = 0
32,768 - 32,768 = 0
0=0

What are the slope and the y-intercept of the linear function that is represented by the table?
natka813 [3]
Slope is 2/5 and the y into is -1/3

I just went with the slope. So I am not sure about the y-int.

Slope= y2 -y1 over x2-x1

(-2/15–1/30) =-.1
—————————- (over)
(-1/2- -3/4) =. -.75

- 0.1 / - 0.25 = .4 = 2/5

*HELP ASAP*
k0ka [10]

Using unit concepts, it is found that:

  • a) Grams.
  • b) Grams.
  • c) Grams squared.
  • d) Grams squared.

-----------------------------

  • For a data-set, the standard deviation has the same unit as the data-set, both for the sample and the population.
  • The variance has the unit squared, both for the sample and the population.
  • For example, if the data-set is in metres, the standard deviation will be in metres while the variance will be in squared metres.

-----------------------------

In this question, the data-set is in grams.

  • The standard deviation, both for the sample and the population, in items a and b, will be in grams.
  • The variance, both for the sample and the population, in items c and d, will be in grams squared.

If S_1=1,S_2=8 and S_n=S_n-1+2S_n-2 whenever n≥2. Show that S_n=3⋅2n−1+2(−1)n for all n≥1.
Snezhnost [94]

You can try to show this by induction:

• According to the given closed form, we have S_1=3\times2^{1-1}+2(-1)^1=3-2=1, which agrees with the initial value <em>S</em>₁ = 1.

• Assume the closed form is correct for all <em>n</em> up to <em>n</em> = <em>k</em>. In particular, we assume

S_{k-1}=3\times2^{(k-1)-1}+2(-1)^{k-1}=3\times2^{k-2}+2(-1)^{k-1}

and

S_k=3\times2^{k-1}+2(-1)^k

We want to then use this assumption to show the closed form is correct for <em>n</em> = <em>k</em> + 1, or

S_{k+1}=3\times2^{(k+1)-1}+2(-1)^{k+1}=3\times2^k+2(-1)^{k+1}

From the given recurrence, we know

S_{k+1}=S_k+2S_{k-1}

so that

S_{k+1}=3\times2^{k-1}+2(-1)^k + 2\left(3\times2^{k-2}+2(-1)^{k-1}\right)

S_{k+1}=3\times2^{k-1}+2(-1)^k + 3\times2^{k-1}+4(-1)^{k-1}

S_{k+1}=2\times3\times2^{k-1}+(-1)^k\left(2+4(-1)^{-1}\right)

S_{k+1}=3\times2^k-2(-1)^k

S_{k+1}=3\times2^k+2(-1)(-1)^k

\boxed{S_{k+1}=3\times2^k+2(-1)^{k+1}}

which is what we needed. QED
