Only number 32,, please
natka813 [3]

Answer:Graph B

Step-by-step explanation: They all had different number of distances. All had different time for finishing that. It's also saying there is transition between each game. So that means there is change of place. In graph B you can see that there are little straight lines, it's the transition part. And we can clearly see the graph in three parts which represents the three games. Graph A doesn't show any transition and graph C shows only 2 games.

The distribution of actual weights of 8-ounce wedges of cheddar cheese produced at a dairy is normal with mean 8.1 ounces and st
Brrunno [24]
The mean of the weight is 8.1 ounces. 
So the means of the distribution of 10 sample will be 10*8.1.
And the mean of 20 <span>cheese wedges is again 20*8.1. 
(The mean of the addition of two normal law is the sum of the 
mean of each law)
Divide the above two numbers: </span>\frac{20\times8.1}{10\times8.1}=2

The distribution of the sample means of the weights of cheese wedges is multiplied by 2 in the new <span>batches</span>.

Determine where f(x) = x2 + 2x - 8 intersects the x-axis.
V125BC [204]
Let f(x) =0.
{x}^{2}  + 2x - 8 = 0 \\ (x + 4)(x - 2) = 0 \\ x + 4 = 0 \\ x =  - 4 \\ x - 2 = 0 \\ x = 2
x=-4, 2

Calc help pretty please
Gre4nikov [31]

Answer:

A.  77.4

Step-by-step explanation:

<u>Linear approximation formula</u>

L(x)=f(a)+f'(a)(x-a)

Given function:

f(x)=(x+1)^2

\boxed{\begin{minipage}{5.4 cm}\underline{Chain Rule for Differentiation}\\\\If  $y=f(u)$  and  $u=g(x)$  then:\\\\$\dfrac{\text{d}y}{\text{d}x}=\dfrac{\text{d}y}{\text{d}u}\times \dfrac{\text{d}u}{\text{d}x}$\\\end{minipage}}

\boxed{\begin{minipage}{5 cm}\underline{Differentiating $x^n$}\\\\If  $y=x^n$, then $\dfrac{\text{d}y}{\text{d}x}=xn^{n-1}$\\\end{minipage}}

\boxed{\begin{minipage}{4 cm}\underline{Differentiating $ax$}\\\\If  $y=ax$, then $\dfrac{\text{d}y}{\text{d}x}=a$\\\end{minipage}}

Use the chain rule to differentiate the function.

\textsf{Let }\:y=u^2\:\textsf{ where }u=(x+1)

Differentiate the two parts separately:

  y=u^2 \implies \dfrac{\text{d}y}{\text{d}u}=2u

  u=x+1 \implies \dfrac{\text{d}u}{\text{d}x}=1

Put everything back into the chain rule formula:

\begin{aligned} \implies \dfrac{\text{d}y}{\text{d}x} & =2u \times 1\\ & = 2u \\ & = 2(x+1)\\ & = 2x+2 \end{aligned}

\textsf{Therefore, }\:f'(x)=2x+2..

The <u>linear approximation</u> at a = 8 is:

\begin{aligned}L(x) & =f(a)+f'(a)(x-a)\\\\\implies L(x) & = f(8)+f'(8)(x-8)\\& = (8+1)^2+(2(8)+2)(x-8)\\& = 81+18(x-8)\\& = 18x-63\end{aligned}

Finally, substitute x = 7.8 into the <u>linear approximation equation</u>:

\begin{aligned}\implies L(7.8) & =18(7.8)-63\\& = 140.4-63\\& = 77.4\end{aligned}
