Answer:

width = 6k², length = 5k + 1

Step-by-step explanation:

Given

A = 30k³ + 6k² ← factor out 6k² from each term

   = 6k²(5k + 1)

Since area = width × length , then

width = 6k² and length = 5k + 1

Answer:

30k³ + 6k²

= 6k²(5k + 1)

because the width is equal to the greatest common monomial factor of 30k³ and 6k²

=> the width = 6k²

=> the length = 6k²(5k+1)/6k² = 5k + 1

Eliza started her savings account with $100. Each month she deposits $25 into her account. Determine the average rate of change
Afina-wow [57]
First, lets create a equation for our situation. Let x be the months. We know four our problem that <span>Eliza started her savings account with $100, and each month she deposits $25 into her account. We can use that information to create a model as follows:
</span>f(x)=25x+100
<span>
We want to find the average value of that function </span>from the 2nd month to the 10th month, so its average value in the interval [2,10]. Remember that the formula for finding the average of a function over an interval is: \frac{f(x_{2})-f(x_{1})}{x_{2}-x_{1} }. So lets replace the values in our formula to find the average of our function:
\frac{25(10)+100-[25(2)+100]}{10-2}
\frac{350-150}{8}
\frac{200}{8}
25

We can conclude that <span>the average rate of change in Eliza's account from the 2nd month to the 10th month is $25.</span>

1. You have three standard decks of cards in front of you. What is the probability of drawing a heart card from all three decks?
Paladinen [302]

Answer:

1.56%

Step-by-step explanation:

A standard deck of cards has 52 cards, and 13 of these are hearts, as there are 4 suits, and 52/4=13. This means the probability of choosing a heart card from a deck of cards is 1/4, or 25%. Now to find the probability of doing this from 3 decks in a row, we simply cube 1/4 to get 1/64, and in percentage this is ~1.56%.
