The expression 87000(1.12)^t represents the population of a town t hears after 1996. By what percent does the population increase each year? Pls help i need it

Answers

Answer:

12%

Step-by-step explanation:

Percentage increase of something is often represented in a formula of a format like this:

X=Ar^t

Where X represents the total amount after t years.

A or 87000 in this case represents the starting value, which is this case is the starting population of the town. r or 1.12 represents the percentage increase, if it increases by 12% than the next year has 1.12 times as many people as the previous year so this is represented by 1.12 rather than say 0.12 which would indicate a 88% decrease instead.  t is the time, no. of years in this case, that has elapsed since 1996.

This formula basically means that a town population of 87000 increases by 12% for every year of time that elapses.

Hope this helped!

The answer to the question is 12%

How can I evaluate this when x=1/2 and y= -5

Answers

Plug in the x and y values
4(1/2)^2 -3(-5)
Apply the exponent so (1/2)^2 or 1/2 • 1/2 which is equal to 1/4

Now you have 4(1/4) -3(-5)
Multiply them out:
4(1/4)=1
-3(-5)=15 [remember a negative times a negative equals a positive]

So now your equation is 1-15

your answer is 1-15= -14

Answer:

Plug in the x and y values

4(1/2)^2 -3(-5)

Apply the exponent so (1/2)^2 or 1/2 • 1/2 which is equal to 1/4

Now you have 4(1/4) -3(-5)

Multiply them out:

4(1/4)=1

-3(-5)=15 [remember a negative times a negative equals a positive]

So now your equation is 1-15

your answer is 1-15= -14

What is 7.5 × 10^18 and 7 × 10^27 plz help ty

Answers

7.5 x 10^18: Since the exponent of the scientific notation is positive, move the decimal point  18 places to the right.

AN: 7500000000000000000

7 x 10^27: Since the exponent of the scientific notation is positive, move the decimal point 27 places to the right.

AN: 7000000000000000000000000000

Answer:

7,500,000,000,000,000,000 and 7,000,000,000,000,000,000,000,000,000

Step-by-step explanation:

I would assume that's in scientific notation, so to solve you need to get it out of scientific notation.

Since the exponent is positive, move it that many places to the right.

For the first one, it would be 7,500,000,000,000,000,000.

For the second one, it would be 7,000,000,000,000,000,000,000,000,000.

If the exponent was negative, you would've moved the decimal to the left instead.

Hope this helped. It's the only way I could think of to solve it.

An athlete's heart beats an average of 150 times per minute,

Total distance run = 26 miles,

Total speed  = 5 minutes per mile,

Calculate the time of the total run of the athlete,

Time = 26 × 5

Time = 130 minutes

Calculate the number of times the heartbeats of the athlete,

Number of times Heart beat = 130 × 150

The number of times Heart beat = 19500 times.

the answer is 172. both x’s are the same. 14-14=0, there is no space between them. since you’re calculating absolute value, you do not take positives or negatives into consideration. 211-39=172. they are 172 (units) apart.

.How much force is needed to accelerate a truck with a mass of 2,000 kg, at a rate of 3 m/s²?

Answers

2,000 kg at a rate of 3 miles per second to the second square

The force needed to accelerate a truck with a mass of 2,000 kg, at a rate of 3 m/s² is 6000 Newtons.

What is force?

Force is the influence of either pull or pushes in the body. Basically, gravitation forces, nuclear forces, and friction forces are the types of forces. For e.g. when the wall is hit by a hand then a force is exerted by the hand on the wall as well as the wall also exerts a force on the hand. There are different laws given to Newton to understand force.

Given:

The mass of the truck = 2000 kg,

The acceleration of the truck = 3 m/s²,

Calculate the force as shown below,

Force needed for truck = Acceleration of truck × mass of the truck,

Force = 2000 × 3

Force = 6000 N

At the beginning of the season, Jamie pays full price for a ticket to see Panters, her favorite baseball team. The Panthers currently have 33 wins and 31 losses. A. Represent the total change in the cost of a ticket given in their losses. B. What is the cost of a ticket for the next game they play?

Answers

Answer:

The answer is B i think

Step-by-step explanation:

Answer:

a) The cost of the ticket decreases by $0.41 for every game loss, therefore after 31 losses, the change in cost of ticket is given as:

Change in cost = -$0.41 × number of losses = -$0.41 × 31 = -$12.71

b) The cost of a ticket for the next game given they have 31 losses is:

Cost of ticket = Initial cost of ticket + change in cost = $49.64 - $12.71 = $36.93
