Anumeha is mowing the lawns for a summer job. For every mowing job, she charges and initial fee of $10 plus a constant fee for e
ExtremeBDS [4]

Answer:

F(t) = 10 +5t

Step-by-step explanation:

Income equals the initial fee plus the hours worked times the hourly rate

We know the initial fee = 10

hours = t

hourly rate =r


F(t) = 10 + r*t

We know a 5 hour job is 35 dollars

35 = 10 + r*5

Subtract 10 from each side

35-10 = 10-10 +5r

25 = 5r

Divide by 5

25/5 = 5r/5

5 =r

The hourly rate is 5

F(t) = 10 +5t

Currently, there are 1,460 wolves in Scataway National Park. If the population of wolves is growing at a rate of 6% every year,
VARVARA [1.3K]

Answer:

P(t) = 1460(1.06)^t

Step-by-step explanation:

Exponential equation for population growth:

The exponential equation for a population after t years is given by:

P(t) = P(0)(1+r)^t

In which P(0) is the initial population and r is the growth rate, as a decimal.

Currently, there are 1,460 wolves in Scataway National Park.

This means that P(0) = 1460

Growing at a rate of 6% every year:

This means that r = 0.06. So

P(t) = P(0)(1+r)^t

P(t) = 1460(1+0.06)^t

P(t) = 1460(1.06)^t

Are these triangles similar? (worth 25 points)
zloy xaker [14]

Find angleK:

Angle k = 180-45-85 = 50

Both triangles have an angle equal to 85 and 45, which makes the 3rd angle in both triangles equal to 50

Because all three angles are the same the triangles are similar.
