1 cubic foot = 7.48 gallons

hence
$\frac{7.48 gal}{1 ft^3} =1$

unit conversion
$\frac{3000 ft^3}{} \times \frac{7.48 gal}{1 ft^3} = 3000 \times 7.48 gal$

3000 x 7.48 =22440

Need help with this function problem

kotykmax [81]

Answer:

see attached

Step-by-step explanation:

To find the inverse function, solve ...

x = f(y)

x = (y^7)/7 -4 . . . . . . . use the definition of f(x)

x +4 = (y^7)/7 . . . . . . add 4

7(x +4) = y^7 . . . . . . multiply by 7

(7(x +4))^(1/7) = y . . take the 7th root

The inverse function is the one shown in the attachment.

The difference between the roots of the quadratic equation x2 -14x +q =0 is 6. Find q

Irina-Kira [14]

Answer:

q = 40

Step-by-step explanation:

When the quadratic has roots p and r, it can be factored as ...

(x -p)(x -r) = x² -(p+r)x +pr

So, the sum of the roots is 14, and their difference is 6. This lets us find the roots from ...

p + r = 14

p - r = 6

2p = 20 . . . add the two equations

p = 10

r = 14 -p = 4

The value of interest is then ...

q = pr = (10)(4)

q = 40

The graph shows the roots to be 4 and 10, as we found.

First mug holds the most

Solution:

Given that,

You are choosing between two mugs

The volume of cylinder is given as:

$V = \pi r^2h$

Where,

r is the radius and h is the height

One has a base that is 5.5 inches in diameter and a height of 3 inches

$radius = \frac{diameter}{2}$

Therefore,

$r = \frac{5.5}{2}\\\\r = 2.75$

Also, h = 3 inches

Thus volume of cylinder is given as:

$V = \pi \times 2.75^2 \times 3\\\\V = 3.14 \times 22.6875\\\\V = 71.23875 \approx 71.24$

Thus first mug holds 71.24 cubic inches

The other has a base of 4.5 inches in diameter and a height of 4 inches

$Radius = \frac{4.5}{2}\\\\r = 2.25$

h = 4 inches

Therefore,

$V = 3.14 \times 2.25^2 \times 4\\\\V = 3.14 \times 20.25\\\\V = 63.585$

Thus the second mug holds 63.585 cubic inches

On comparing, volume of both mugs,

Volume of first mug > volume of second mug

First mug holds the most
