When multiplying exponential terms with the same base, which best explains how to simplify the expression?

ololo11 [35]

Answer:

First answer: "Add the exponents"

Step-by-step explanation:

The laws of exponents include the following for product of exponents with the same base:

$x^a\,*\,x^b = x^{a+b}$

which implies addition of exponents

So you need to add exponents

Suppose the wholesale price of a certain brand of medium-sized eggs p (in dollars/carton) is related to the weekly supply x (in

Mrrafil [7]

Answer:

1300

Step-by-step explanation:

We are given

x = 35

$\frac{dp}{dt}=-0.05$ [rate of change of price with time]

We want to find $\frac{dx}{dt}$ , which is the rate at which supply is changing.

First, we need to implicitly differentiate the equation given:

$625p^2-x^2=100\\1250p\frac{dp}{dt}-2x\frac{dx}{dt}=0$

Here, we have what we need except for p. We find p when x = 35:

$625p^2 - x^2 =100\\625p^2 - (35)^2 =100\\625p^2=1325\\p=1.46$

Now, find dx/dt:

$1250(1.46)(-0.05)-2(35)\frac{dx}{dt}=0\\-91.25-70\frac{dx}{dt}=0\\\frac{dx}{dt}=-1.30$

In thousands, 1.30 * 1000 = 1300 cartons per week decrease

Javier volunteers in community events each month. He does not do more than five events in a month. He attends exactly five event

enot [183]

Answer:

$P(x < 3) = 25\%$

$E(x) = 3$

Step-by-step explanation:

The given parameters can be represented as:

$\begin{array}{ccccccc}x & {5} & {4} & {3} & {2} & {1}& {0} & P(x) & {25\%} & {30\%} & {20\%} & {15\%} & {5\%} & {5\%} \ \end{array}$

Solving (a): P(x < 3)

This is calculated as:

$P(x < 3) = P(x = 0) + P(x = 1) + P(x =2)$ ----- i.e. all probabilities less than 3

So, we have:

$P(x < 3) = 5\% + 5\% + 15\%$

$P(x < 3) = 25\%$

Solving (b): Expected number of events

This is calculated as:

$E(x) = \sum x * P(x)$

So, we have:

$E(x) = 5 * 25\% + 4 * 30\% + 3 * 20\% + 2 * 15\% + 1 * 5\% + 0 * 5\%$

$E(x) = 125\% + 120\% + 60\% + 30\% + 5\% + 0\%$

$E(x) = 340\%$

Express as decimal

$E(x) = 3.40$

Approximate to the nearest integer

$E(x) = 3$
