how do i slove 5/9v+w=z, for v

nekit [7.7K]

Okay, let's do this~

we want v isolated on one side so let's bring w over through subtraction

now we have 5/9v=z-w

now, to get rid of that fraction attached to v, we will multiply it's reciprocal on both sides.

*the reciprocal of 5/9 is 9/5

(5/9) x (9/5) cancel each other leaving v isolated to the left

the other side should look like this 9/5(z-w)

now we put both parts together to end up with:

v= 9/5(z-w)

there you go! :D

A mirror with a parabolic cross section is used to collect sunlight on a pipe located at the focus of the mirror. The pipe is lo

vodomira [7]

Answer: $x^2=32y$

Step-by-step explanation:

Given: A mirror with a parabolic cross section is used to collect sunlight on a pipe located at the focus of the mirror.

The pipe is located 8 inches from the vertex of the mirror.

Assume the vertex is at the origin.

If the parabola opens upwards

then the coordinates of focus= (0,8)

We know that equation of parabola with focus (0,a) and open upards is of the form (vertex=(0,0)) is

$x^2=4ay$

Substitute the value of a=8 in equation, we get

$x^2=4\times8y$

$\Rightarrow\ x^2=32y$

Therefore, equation of the parabola that models the cross section of the mirror is $x^2=32y$

The gas tank of the truck holds 30 gallons the gas tank of a passenger car holds 50% less how many gallons does it hold?

love history [14]

Answer:

15 gallons

Step-by-step explanation:

To find how much the passenger car holds, we need to first find what 50% of the trucks gas tank holds.

Truck Gas Tank = 30 gallons

Now we find how much 50% of 30 is:

50% = 0.50

Total = 30 x 0.50

Total = 15 Gallons

So the passenger car holds 15 gallons of gas.

Gemiola [76]

Use:

$\dfrac{1}{a}=a^{-1}\\\\\dfrac{1}{a^n}=a^{-n}$

$\dfrac{3a^2b^3c^5}{8x^4y^3z}=3a^2b^3c^5\cdot8^{-1}x^{-4}y^{-3}z^{-1}$

Answer: 3"8^-1a^2b^3c^5x^-4y^-3z^-1
