A population of 240 birds increases at a rate of 16% annually. Jemel writes an exponential function of the form f(x) =
ab' to represent the number of birds after x years. Which values should she use for a and b?
a
b =

Answers

Answer 1

Answer: A = 240(1.16)^x

a= 240

b= 1.16

Step-by-step explanation:

Hi, to answer this question we have to apply an exponential growth function:  

A = P (1 + r) t  

Where:  

p = original population  

r = growing rate (decimal form)  

t= years  

A = population after t years  

Replacing with the values given:  

A =240(1+ 16/100)^x

A = 240(1.16)^x

If it is in the form: f(x) = ab'

a= 240

b= 1.16

Feel free to ask for more if needed or if you did not understand something.

which expression is not equivalent to the other three?
a) 2x + 2+ 2x + 3x – 8
b) 4 + 7x – 2
c) –2 + 5x + 2x – 4
d) 8x – x – 6

Answers

Answer:  Choice B

4+7x-2

========================================================

Explanation:

Combine the like terms in choice A to find that:

2x+2x+3x = 7x2-8 = -6

Therefore, choice A simplifies to 7x-6.

Choice B on the other hand simplifies to 7x+2 since 4-2 = 2.

The expressions 7x-6 and 7x+2 don't match up, which means the answer is either choice A or choice B.

--------------

Let's simplify choice C.

5x+2x = 7x-2-4 = -6

Choice C simplifies to 7x-6 which matches with choice A. In other words, choices A and C are equivalent expressions. We can rule out choice A and go with  choice B   as the final answer.

For the sake of completeness, let's simplify choice D

8x-x-6 = 7x-6

This shows choice D matches with A and C.

--------------

Summary:

Choice A simplifies to 7x-6Choice B simplifies to 7x+2Choice C simplifies to 7x-6Choice D simplifies to 7x-6

Edwin runs two laps in 12 minutes.
What is The number of laps he could run in an hour.

What is The time it would take to run one lap.

What is The time it would take to run three laps.

Answers

Answer:6 minutes a lap

for 3 laps = 18

Step-by-step explanation:

12/2 = 6

6 times 3 = 18

Well 12 divided by 2 is 6

6 is the unit rate so it would take 6 mins to run one lap.

I’m one hour, he could run 10 laps.

So... it would take 18 minutes to run 3 laps.

The telephone company offers two billing plans for local calls. Plan 1 charges ​$29 per month for unlimited calls and Plan 2 charges ​$19 per month plus ​$0.05 per call.
a. Use an inequality to find the number of monthly calls for which Plan 1 is more economical than Plan 2.
b. Explain the meaning of the answer to part a.

Answers

Answer:

Step-by-step explanation:

wouldn't you do 29 x 19=551+0.05=551.05

Answer:

The number of monthly calls for which Plan 1 is more economical than Plan 2 is 200 calls If more than 200 calls are made, the plan 1 charge will be more than plan 2. Let the number of charges per month be x  If plan 2 charges ​$16 per month plus ​$0.04 per call, this is expressed as 0.04x + 16  Price that pan 1 charges = $24  If Plan 1 is more economical than Plan 2, this is expressed as:0.04x + 16 > 24 Subtract 16 from both sides:0.04x + 16 - 16 > 24 - 16   0.04x > 8 x = 6/0.04 x = 200 This shows that if more than 200 calls are made, the plan 1 charge will be more than plan 2.

The missing vertices of the pararllelogram is D(- 4, 0).

What is a parallelogram?

A basic quadrilateral with two sets of parallel sides is known as a parallelogram. In a parallelogram, the opposing or confronting sides are of equal length, and the opposing angles are of equal size.

The area of a parallelogram is base multiples by height as two triangles form a parallelogram.

We know the diagonals of a parallelogram bisect each other.

Given, Three of the four vertices (corners) of a parallelogram are A(-2,7), B(3,7), and C(2,5) and assuming the fourth vertices is D(x, y).

∴ The midpoint of BD is equal to the midpoint of AC.

Midpoint of a line segment joining the point (x₁, y₁) and (x₂, y₂) is

(x₁ + x₂)/2, (y₁ + y₂)/2.

So, (3 + x)/2, (7 + y)/2 = (-2 + 3)/2, (7 + 7)/2.

(3 + x)/2 = -1/2.

3 + x = - 1.

x = - 4 And,

(7 + y)/2 = 14/2.

7 + y = 7.

y = 0.

So, D(- 4, 0).

| -16+51 | absolute value

Answers

Answer: 35.

Step-by-step explanation:

The absolute value of a number is the non-negative value of the number without regard to its sign. It may be thought of as the distance of the number from zero on a number line. It is symbolized by two vertical lines, as |3| or |−3| is equal to 3. For complex numbers, the absolute value is the positive square root of the sum of the squares of the real and imaginary parts. The absolute value is used to determine the numeric value of a quantity, irrespective of sign, that has no meaning for the sign.

To find the absolute value of -16+51, you need to simplify the expression first and then apply the definition of absolute value. -16+51 = 35, so | -16+51 | = | 35 |. Since 35 is a positive number, its absolute value is itself. Therefore, | -16+51 | = 35.

Segment W: 2-6 hours     Desc.:  Depth declines from 7ft. to 5ft. at a rate of 0.5ft per hour.
Segment X: 6-8 hours      Desc.: Depth steadily drops from 5ft. to 0ft. at a rate of 2.5ft per hour
Segment Y: 8-14 hours     Desc.: Depth remains at 0ft.
Segment Z: 14-20 hours   Desc.: Depth rises from 0ft to 9ft at a steady rate of 1.5ft per hour.

A: There is simply no explanation or answer given as to why they emptied the pool, and there are multiple reasons why they could've, so there isn't enough information to determine why the swimming pool was emptied and refilled.
B: Each line is straight. From 0 hours to 2 hours, the line is at 7ft, and it's horizontal, but it's also straight.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?

Answers

To determine whether Keira's statement is correct, we need to analyze the information provided.

According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.

If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.

However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.

Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
in order to know if Keira has two tickets left, we need to know the first number of tickets without that number there is no way to find the remainder
