Determine whether the variation between the indicated quantities is direct or inverse. The number of calories in a cheese pizza
-BARSIC- [3]

Answer:

The variance is direct.

Step-by-step explanation:

Since size of the pizza determines the amount of calories.

Let us say that a 2" x4" strip of pizza has 250 calories.

Then a pizza of twice the size (or 4" x 4") will have twice as many calories (500 calories) .

Joe's Plumbing and Mark's Plumbing have different ways of charging their customers. The function defined by J(t)=45t represents
puteri [66]

Answer:

Joe's Plumbing charges more per hour ($45) than Mark's Plumbing (S40)

Step-by-step explanation:

Let

t ------> the number of hours

J(t) ---->the total amount in dollars that Joe's  Plumbing charges

M(t) ---->the total amount in dollars that Mark's  Plumbing charges

we know that

The linear equation in slope form is equal to

f(x)=mx+b

where

m is the slope or rate of the linear equation

b is the y-intercept (initial value)

In this problem we have

<em>Joe's  Plumbing</em>

J(t)=45t

The slope or rate is equal to

m=\$45\ per\ hour

b=\$0

Mark<em>'s  Plumbing</em>

M(t)=40t+25

The slope or rate is equal to

m=\$40\ per\ hour

b=\$25

therefore

Joe's Plumbing charges more per hour ($45) than Mark's Plumbing (S40)

The wind power of a given wind turbine, P(v), depending on the wind speed in meters per second, v, can be found using the functi
PIT_PIT [208]

Answer:

18 m/s

Step-by-step explanation:

We used the given expression for the wind power: P(v)=0.002713v^3 replacing the power (on the left hand side of the equal sign) by 15.83 MegaWatts, and then solve for v which is raised to the power 3:

P(v)=0.002713v^3\\15.83=0.002713v^3\\\frac{15.83}{0.002713} =v^3\\v^3=5834.87\\v=\sqrt[3]{5834.87} =18.003\frac{m}{s}
