Answers
To know which function has the largest value for f(3), we need to substitute x=-3 in each function:
A. f(x)=2x-5
f(-3)=2(-3)-5=-11
B. f(x)=2-4x
f(-3)=2-4(-3)=14
C. f(-3)=6-3^(-3)
f(-3)=6-1/27
f(-3)=161/27
D. f(x)=2^(x)+10
f(-3)=2^(-3)+10
f(-3)=1/8+10=81/8
The largest value for f(-3) is 14, The answer is B f(x)=2-4x

how long will it take for the population to reach 5656 fish, according to this model?
Answers
Question:
Solution:
The population growth is given by the following equation:
[tex]P(t)=(707)2^{\frac{t}{3}}[/tex]where P represents the number of individuals and t represents the number of years from the time of introduction. Now, if we have a population of 5656 fish, then the above equation becomes:
[tex]5656=(707)2^{\frac{t}{3}}[/tex]this is equivalent to:
[tex]2^{\frac{t}{3}}\text{ = }\frac{5656}{707}[/tex]this is equivalent to:
[tex]2^{\frac{t}{3}}\text{ = }8[/tex]this is equivalent to:
[tex](2^t)^{\frac{1}{3}}\text{ = }8[/tex]now, the inverse function of the root function is the exponential function. So that, we can apply the exponential function to the previous equation:
[tex]((2^t)^{\frac{1}{3}})^3\text{ = }8^3[/tex]this is equivalent to:
[tex](2^t)^{\frac{3}{3}}^{}\text{ = }512[/tex]this is equivalent to:
[tex]2^t\text{ = }512[/tex]now, we can apply the properties of the logarithms to the previous equation:
[tex]\log _2(2^t)\text{ = }log_2(512)[/tex]this is equivalent to:
[tex]t=log_2(512)\text{ = 9}[/tex]we can conclude that the correct answer is:

a student says that the solution of 375=x-28 is 347 explain the students error and find the correct answer
Answers
The given equation is:
375 = x - 28
To solve the equation:
Collect like terms
The -28 crosses the equality sign to the left and becomes 28
The equation then becomes:
375 + 28 = x
x = 403 (correct answer)
The students error is that when he collected like terms, he did not change the "-" sign in -28 to +
He did 375 - 28 = x
x = 347 (wrong)

Solution
We can create the solution with the following tree diagram:
Part 2
For this case we want this probability:
P(rain and accident)
And we can do this operation:
P(rain and accident) = 0.75 *0.5 = 0.375
Part 3
For this case we want this probability:
P( no rain and accident)
And we can do this operation:
P(no rain and accident) = 0.25 *0.25 = 0.0625
Part 4
P(Accident) = 0.5*0.75 + 0.25*0.25= 0.4375

Answers
We have 12 cards, each one with a different number, so the probability of each card being picked is 1/12.
Since all these cards have numbers that are greater than 0, all the 12 cards are correct options to being picked.
Adding the probability of all 12 cards, we have 12/12, that is, 1 or 100%.
So the probability of picking a card with a number greater than 0 is 1 or 100% (that is, every card has a number greater than 0).

Answers
The sample size you need to have a margin of error equal to $1,000 with 95% confidence is; 508
How to find the sample size?Formula for margin of error is given by the formula;
E = z(σ/√n)

n is sample size
We are given;
σ = $11500
z at significance level of 0.05 is 1.96
margin of error; E = $1000
Thus;
1000 = 1.96(11500/√n)

The numeric sentence (A) 6 × (5 + 8) = (6 × 5) + 8 represents the distributive property of multiplication.
What is the distributive property of multiplication?The distributive property of binary operations in mathematics generalizes the distributive law, which states that in elementary algebra, equality is always true. According to the distributive property of multiplication, the first number can be distributed among both of the other numbers and multiplied by each of them independently before adding the results to produce the same outcome as multiplying the first number by the sum.So, the distributive property of multiplication:
a × (b + c) = (a + b) × cSo, in the given options, only option (A) is similar to the distributive property of multiplication.

A skating rink manager finds that revenue R based on an hourly fee F
for skating is represented by the function R = -480F² + 3120F.
What hourly fee will produce maximum revenues?
Answers
The hourly fees of $3.25 will produce the maximum value of revenue in the Skating rink.
Given function of the form:
R = -480F² + 3120F
Here R is the revenue and F is the hourly fees.
Now we will differentiate with respect to F
Hence.
[tex]\frac{dR}{dF} = -960F + 3120[/tex]
Now to find the maximum value we have to find the value of F for which [tex]\frac{dR}{dF}[/tex] is zero.
hence :
-960F+3120 = 0
or, F=3.25
Hence the value of F is 3.25 for which the revenue will be maximum.

Ma spends $12.78 on 2 jump ropes at the sale price. What was the price of 1 jump rope before the sale? Enter the answer in the box. $
Answers
Answer : $8.29
A shop sells jump ropes
Ma spends $12.78 on 2 jump ropes after removing $1.90 on each jump rope
Since, she spents $12. 78 on two jump ropes
$1.90 is removed from each
For the two jump rope, we have
2 x 1.90 = $3.80
This means $3.80 is removed from the two jump ropes
The total amount spents on the two jump rope before the removal is
$12.780 + $3.80
The total amount = $16.58
The total amount spents on the two jump ropes before the sales is $16.58
Since each jump rope cost the same price
Then
16.58/2 = $8.29
Therefore, the price of each jump rope is $8.29
