The number of views on a viral video can be modeled by the function Q(t)=410(5)^{2t}.Q(t)=410(5) 2t . Write an equivalent function of the form Q(t)=ab^t.Q(t)=ab t .
Answers
Answer: Q(t) = 410*(5)^(2t) = 410*(5^2)^t = 410*(25)^t
Step-by-step explanation:
We start with the equation:
Q(t) = 410*(5)^(2t)
And we want to rewrite this in the form:
Q(t) = a*b^t
To do this, we need to use the property:
(a^x)^y = a^(x*y)
Using this, we can rewrite:
Q(t) = 410*(5)^(2t) = 410*(5^2)^t = 410*(25)^t
And this is the form that we wanted:

Michael has 3 quarters, 2 dimes, and 3 nickels in his
pocket. He randomly draws two coins from his pocket,
one at a time, and they are both dimes. He says the
probability of that occurring is because 2 of the 8
coins are dimes. Is he correct? Explain.
Answers
My Answer:
The events are dependent.
The size of the original sample space is 8. It changes to 7 after the first dime is chosen.
The probability of picking the first dime is 2/8.
The probability of picking the second dime is 1/7
To find the probability of the compound event, multiply the probabilities.
I got it correct, on edge 2020/2021
Answer:
No. Choosing two dimes are dependent events. The probability of choosing the first dime is 14 and the probability of choosing the second dime is 17 . The probability that both coins are dimes is (14)(17) = 128.

Answers
Answer:
the 17 books should be put in each pile
Step-by-step explanation:
The computation of the number of books in each pile is shown below:
Given that
There are 119 books
And there are 7 piles
So, the number of books in each pile is
= 119 books ÷ 7 piles
= 17 books
Hence, the 17 books should be put in each pile

If Mr. Jones buys paddles for $35 instead of $50 and uses the same percent increase on price how many paddles most Mr. Jones sell for the total paddle sales before tax and to be at least $250 explain your answer
Answers
Answer: 4 paddles
Step-by-step explanation:
Mr. Jones buys the paddle for $35 and sells at 180% of the purchase price:
= 35 * 180/100
= $63
For the number of paddle sales to be at least $250, he should sell:
= 250/63
= 3.97
= 4 paddles
line a passes through points (5,8) and (10,6). line b is perpendicular to a. what is the slope of line b?
Answers
Answer:
2/5
Step-by-step explanation:
First, we need to find the slope of line a. To do this, we subtract the two y values and then the two x values and divide these two differences.
10-5=5
6-8=-2
5/-2= -5/2
A perpendicular line's slope will always be equal to the negative reciprocal of the intersects. So, we just flip the numerator and denominator and then add a negative to our first slope to get the slope of line b.

Answer:
We conclude that the slope between (s, t) and (u, v):
slope = [v - t] / [u - s]Step-by-step explanation:
We can find the slope between two points (x₁, y₁) and (x₂, y₂) using the formula
slope = [y₂ - y₁] / [x₂ - x₁]
In our case, the two points are
(x₁, y₁) = (s, t)
(x₂, y₂) = (u, v)
Thus, the slope between (s, t) and (u, v)
slope = [v - t] / [u - s]
Therefore, we conclude that the slope between (s, t) and (u, v):
slope = [v - t] / [u - s]There is a average of 50,000 spiders per acre in green areas, How many spiders would be in 1/4 of an acre?

She uses 13 of her supply of sunflower seeds to make a salted snack mix and 29 of her supply to make an unsalted snack mix. If Cecile uses 10 pounds of sunflower seeds, how many pounds of seeds are in her supply?
Answers
Answer:
18 pounds
Step-by-step explanation:
Here is the full question :
Cecile packages snack mix at a health food store.
She uses 1/3 of her supply of sunflower seeds to make a salted snack mix and 2/9 of her supply to make an unsalted snack mix. If Cecile uses 10 pounds of sunflower seeds, how many pounds of seeds are in her supply?
Let x = Cecile's supply
1/3 of x = 1/3x
2/9 of x = 2/9x
1/3x + 2/9x = 10
adding the fraction together gives 5/9
5/9 x = 10
solve for x = 18 pounds
