Write an equation for the line in slope intercept

The exponential function for the new participants is f(x) = 3 * 4^x

Let's start with the initial number of participants who sent selfies on Day 0.

We know that Aliyah, Kim, and Reese each sent selfies to 4 friends, so there are 3 x 4 = 12 participants on Day 1.

On Day 2, each of these 12 participants will send selfies to 4 friends, so we will have 12 x 4 = 48 new participants.

We can see that the number of new participants each day is increasing exponentially. In fact, the number of new participants each day is multiplied by 4, since each participant sends selfies to 4 friends.

Therefore, we can write an exponential function of the form:

f(x)=a * 4^x

Where x is the number of days since the challenge started, and $a$ is the initial number of participants who sent selfies on Day 0.

We know that a = 12 from our earlier calculations.

So, we have

f(x) = 3 * 4^x

Hence, the function is f(x) = 3 * 4^x

Answer:

The answer is D

Step-by-step explanation:

To find the number of people who didn't use any facilities, we can subtract the total number of people who used at least one facility from the total number of people in the sport centre.

Given that there are 130 people in the sport centre, and we have information about the number of people using each facility and the number of people using multiple facilities, we can calculate the number of people who didn't use any facilities as follows:

Total number of people using at least one facility = (people using the gym) + (people using the swimming pool) + (people using the track) - (people using both gym and pool) - (people using both pool and track) - (people using both gym and track) + (people using all three facilities)

Substituting the given values into the equation:

Total number of people using at least one facility = 73 + 62 + 58 - 22 - 29 - 25 + 11 = 128

Number of people who didn't use any facilities = Total number of people in the sport centre - Total number of people using at least one facility

Number of people who didn't use any facilities = 130 - 128 = 2

Therefore, there are 2 people who didn't use any facilities.

The function that represents how many more texts that were sent this week than last week is: B. (f − g)(x) = 3x + 16.

How to Evaluate Functions?

To find the value of a given functional expression, we have to apply the basic knowledge of how to solve algebraic expressions.

For example, if we are given that (f - g)(x), it means we are to subtract the function g(x) from f(x). That is (f - g)(x) = f(x) - g(x).

Given the following functions:

Number of texts sent this week is represented as the function, f(x) = 8x + 14

Number of texts sent last week is represented as the function, g(x) = 5x - 2.

Number of texts that were sent this week than last week = (f - g)(x)

(f - g)(x) = (8x + 14) - (5x - 2)

(f - g)(x) = 8x + 14 - 5x + 2

(f - g)(x) = 3x + 16

Therefore, the answer is: (f − g)(x) = 3x + 16.

Step-by-step explanation:

To find (f - g)(x), we need to subtract the function g(x) from the function f(x).

(f - g)(x) = f(x) - g(x)

Substituting the given functions for f(x) and g(x), we get:

(f - g)(x) = (8x + 14) - (5x - 2)

Simplifying this expression, we get:

(f - g)(x) = 8x + 14 - 5x + 2

(f - g)(x) = 3x + 16

Therefore, the answer is B: (f − g)(x) = 3x + 16.

(A) When x=4, (AB)(4) = 2(4)³ + 3(4)² - 5(4) - 5 = 91. This means that the area of the rectangular tile when x=4 is 91 square inches.

(B) The expression (AB)(x) represents the area of the rectangular tile in square inches.

What is an algebraic expression?

An algebraic expression is a mathematical phrase that contains variables, constants, and mathematical operations. It may also include exponents and/or roots.

A(x) represents the length of the rectangular tile in inches, and B(x) represents the width of the rectangular tile in inches.

A)

To find (A+B)(x), we add the expressions A(x) and B(x):

(A+B)(x) = A(x) + B(x)

= x² + 5 + 2x - 1

= x² + 2x + 4

When x=4, (A+B)(4) = 4² + 2(4) + 4 = 24. This means that the sum of the length and width of the tile when x=4 is 24 inches.

To find (AB)(x), we multiply the expressions A(x) and B(x):

(AB)(x) = A(x) * B(x)

= (x² + 5)(2x - 1)

= 2x³ + 3x² - 5x - 5

When x=4, (AB)(4) = 2(4)³ + 3(4)² - 5(4) - 5 = 91. This means that the area of the rectangular tile when x=4 is 91 square inches.

B)

The expression (AB)(x) represents the area of the rectangular tile in square inches. This is because the product of the length (A(x)) and width (B(x)) of a rectangle gives its area. So (AB)(x) is the formula for the area of the rectangular tile, which is a quadratic function of x.

Therefore, the derivative of h(z) is h'(z) = 4az/(a^2 - z^2)^2.

To differentiate the given function h(z) = ln[(a^2 - z^2)/(a^2 + z^2)], we use the chain rule and the quotient rule of differentiation.

The chain rule tells us that if we have a function inside another function, we must first differentiate the outer function with respect to the appropriate variable, and then multiply by the derivative of the inner function with respect to the same variable. In this case, we have the natural logarithm function inside the larger expression, so we use the chain rule to differentiate it.

The quotient rule tells us that if we have a fraction where the numerator and denominator are both functions of the same variable, we can differentiate the expression by first differentiating the numerator and denominator separately, and then combining them using a specific formula. In this case, we have a fraction where the numerator and denominator are both functions of z, so we use the quotient rule to differentiate it.

h'(z) = d/dz [ln[(a^2 - z^2)/(a^2 + z^2)]]

= 1/[(a^2 - z^2)/(a^2 + z^2)] * d/dz [(a^2 - z^2)/(a^2 + z^2)]

= (a^2 + z^2)/(a^2 - z^2) * d/dz [(a^2 - z^2)/(a^2 + z^2)]

= (a^2 + z^2)/(a^2 - z^2) * [(d/dz)(a^2 - z^2)/(a^2 + z^2) - (a^2 - z^2)/(a^2 + z^2)^2 * (d/dz)(a^2 + z^2)]

= (a^2 + z^2)/(a^2 - z^2) * [(2z)/(a^2 + z^2) - 2z/(a^2 - z^2)]

= 4az/(a^2 - z^2)^2

The equation 70 = 14t can be used to find the number of teams in the contest. By solving this equation, we found that there were 5 teams in the contest.

70 = 14t

To find the number of teams in the contest, we can use the equation 70 = 14t. This equation states that the total number of water balloons, 70, is equal to the number of teams, t, multiplied by the number of balloons each team gets, 14.

To solve this equation, we can divide both sides of the equation by 14. This will give us the equation t = 70/14. We can then simplify this equation by dividing 70 by 14. This gives us t = 5. This means that there are 5 teams in the contest.

Therefore, the equation 70 = 14t can be used to find the number of teams in the contest. By solving this equation, we found that there were 5 teams in the contest.
