Answer:

7. 4⁴ = 4x4x4x4=256
   4³= 4x4x4=64
   4²= 4x416

   4¹=4
   4⁰=1 ( as every number that has power 0 = 1)

8. (-2)⁴

=(−2)*(−2)*(−2)*(−2)

=(-2)⁴

=16

(−2)³

=(−2)*(−2)*(−2)

=(−2)³

=−8

(−2)²

=(−2)*(−2)

=(−2)²

=4

(−2)¹

=−2

(−2)⁰

=1 ( ( as every number that has power 0 = 1)

Solution:

<u>We know the following rules:</u>

  • Rule: If an exponent is negative, it will be in the fraction 1/nˣ.
  • Rule: If an exponent is positive, it will be in whole number form and will multiply itself m times.
  • Rule: if a number's exponent is 0, then the number is 1.

Now, let's solve each problem.

<u>Question-7</u>

  • 4³ = 4 x 4 x 4 = 64
  • 4² = 4 x 4 = 16
  • 4¹ = 4
  • 4⁰ = 1

<u>Question-8</u>

  • (-2)³ = (-2) x (-2) x -(2) = -8
  • (-2)² = (-2) x (-2) = 4
  • (-2)¹ = -2
  • (-2)⁰ = 1

For the wheel pictured on the right, assume that a person spins the pointer and is awarded the amount indicated by the pointer.
Anuta_ua [19.1K]

The expectation value is given by:

EV=\sum_{i\mathop{=}1}^nx_iP(x_i)

In this case we just have two options, each with probability 1/2, and the values of x are 2 and 9; then we have:

\begin{gathered} EV=(2)(\frac{1}{2})+(9)(\frac{1}{2}) \\ EV=2+\frac{9}{2} \\ EV=\frac{13}{2} \\ EV=6.5 \end{gathered}

Therefore, the expectation is $6.5

Let r(t)=⟨t2,1−t,4t⟩. calculate the derivative of r(t)⋅a(t) at t=5, assuming that a(5)=⟨−4,4,−5⟩ and a′(5)=⟨−5,9,3⟩
erastovalidia [21]
\mathbf r(t)=\langle t^2,1-t,4t\rangle
\implies\mathbf r'(t)=\langle 2t,-1,4\rangle

\dfrac{\mathrm d(\mathbf r(t)\cdot\mathbf a(t))}{\mathrm dt}\bigg|_{t=5}=\mathbf r'(5)\cdot\mathbf a(5)+\mathbf r(5)\cdot\mathbf a'(5)
=\langle10,-1,4\rangle\cdot\langle-4,4,-5\rangle+\langle25,-4,20\rangle\cdot\langle-5,9,3\rangle
=(-40-4-20)+(-125-36+60)
=-165

You roll a fair 6-sided die what is p (not 3)
Ulleksa [173]
As a fraction, the exact answer is 5/6
In decimal form, the approximate answer is 0.8333

To get this answer, note how there are 5 ways to roll something that isn't a three (1,2,4,5,6) out of 6 ways total (1,2,3,4,5,6)

So you simply divide the two values to get 5/6 = 0.8333
