What is the equation of a line parallel to y=-4x-7 that passes through 2,29

1 answer:

Parallel means the slopes are equal, so -4 stays the same, and for the line to fall on (2,29) the y int must be 37.

so, answer: y=-4x+37

Answer:

P * 300000 = 30

.01%

Step-by-step explanation:

Let P equal the percent. Of means multiply and is means equals

We need to make sure the units are the same. I will convert km to cm

3 km *1000m/1km * 100cm/1m =300000 cm

Now we can write the equation

P * 300000 = 30

Divide each side by 300000

P 300000/300000 = 30/300000

P =.0001

Changing this from decimal to percent

P = .0001*100 = .01 %

Two boys divided $3.36 so that one boy received 12 cents less than three times as much as the other. How was the money divided?

Fed [463]

Let's first convert that amount of money into cents, which makes 336 cents. Then, let's denote the amount of money one of the boys has with x. The other boy has got 3x-12 amount of money. We can construct an equation. $3x-12+x=336$ . Solving it we find that x=87 cents or $ 0.87 and the other boy holds $2.49 amount of money.

Find the flow rate through a tube of radius 6 cm, assuming that the velocity of fluid particles at a distance r cm from the cent

vaieri [72.5K]

Answer:

791.68 cm/s

Step-by-step explanation:

The volume flow rate can be interpreted as the integral of fluid velocity over area

$\dot{V} = \int\limits^6_0 {v(r) 2\pi r} \, dr\\\dot{V} = 2\pi\int\limits^6_0 {(25-r^2)r} \, dr\\\dot{V} = 2\pi\int\limits^6_0 {25r-r^3} \, dr\\\\\dot{V} = 2\pi[12.5r^2 - r^4/4]_0^6\\\dot{V} = 2\pi(12.5*6^2 - 6^4/4 - 12.5*0 - 0)\\\dot{V} = 2\pi*126 = 791.68 cm/s$
