A population of 6000 animals decrease at an annual rate of 0.7%. What is the expected population in 12 years? Round your answer

solmaris [256]

Answer:

The population is expected to be 5515 animals in 12 years.

Step-by-step explanation:

This problem can be solved by using a compounded interest formula with a negative interest rate, since the number of animals are decreasing. We have:

final population = initial population * (1 - r)^(t)

Where r is rate of decline and t is the time elapsed. Applying the data from the question we have:

final population = 6000*(1 - 0.007)^(12)

final population = 6000*(0.993)^12 = 5514.9582 animals

The population is expected to be 5515 animals in 12 years.

Lian is paid for SR 75 per hour. Using p for her pay and h for the hours of work, which function rule represents

Andru [333]

Answer:

The function p = 75h represents this situation.

Step-by-step explanation:

We know the equation of linear equation in the slope-intercept form is

$y = mx+b$

where

m = rate of change = slope

b = y-intercept

Let 'h' be the number of hours

Let 'p' be the pay

Given that Lian is paid SR 75 per hour.

so the rate of change of slope = m = 75

As there is no initial condition, so b = 0

as

y = mx+b

Now, mapping the information data into the slope-intercept form

p = y

m = 75

h = x

b = 0

Thus, the equation becomes

p = 75h

Therefore, the function p = 75h represents this situation.

VERIFICATION:

Given the equation

p = 75h

for h = 1

p = 75(1)

p = 75

Thus, Liam is paid SR 75 per hour.

20 points for u if u teach me how to do this and answer the questions for me

ivann1987 [24]

First write down the formula which is: y=mx+b
M is the slope and B is the y-intercept
The slope is rise/run, so if your slope is 2 then, 2 is your rise and 1 is your run
In order to find the y intercept you have to plot the points given in your question and and move your rise down and moving the run to the left until you find your y-intercept
Once you find the y-intercept, just plug in your slope and y-intercept

Solve for x. M=5/dx+e

snow_lady [41]

After solving $M=\frac{5}{dx}+e$ we get value of x: $x=\frac{5}{(M-e)d}$

Step-by-step explanation:

We need to solve the equation $M=\frac{5}{dx}+e$ to find value of x

Solving

$M=\frac{5}{dx}+e$

Adding -e on both sides

$M-e=\frac{5}{dx}+e-e$

$M-e=\frac{5}{dx}$

Multiply both sides by dx

$dx(M-e)=5$

Divide both sides by M-e

$dx=\frac{5}{M-e}$

Divide both sides by d

$x=\frac{5}{(M-e)d}$

So, After solving $M=\frac{5}{dx}+e$ we get value of x: $x=\frac{5}{(M-e)d}$

What is the volume of a sphere with a diameter of 8 m use 3.14 for pie round your answer to the nearest hundredth

deff fn [24]

Volume of the sphere is 300 m³

Step-by-step explanation:

Step 1: Calculate volume of the sphere using the formula V = 4/3πr³, where r = d/2 = 4m

⇒ V = 4/3 × 3.14 × 4³ = 267.95 = 300 m³ (rounding off to the nearest hundredth)
