Answer:

Q = 3.2

Step-by-step explanation:

So basically you would first re-order the equation. 6.4 + Q = 9.6

Then after that you will move all the terms containing Q to the left and the rest of them on the right. After that you will -6.4 to both sides of the equation. Which will look like this.

6.4 + (-6.4) + Q = 9.6 + (-6.4)

Then you will combine the like terms.

6.4 + (-6.4) = 0.0

0.0 + Q = 9.6 + (-6.4)

Answer:B

Step-by-step explanation:

4x2 =121

4x2-121=0

using the general formula

[-b( +/-) √b2-4ac]/2a

a=4, b= 0, c=-121

x= [0 ( +/-)√02-(4*4*-121)]/2.4

= ( +/-)√1936)/8 = ( +/-)5.5

x =5.5

x = -5.5

Gravel is being dumped from a conveyor belt at a rate of 15 ft3/min, and its coarseness is such that it forms a pile in the shap

gayaneshka [121]

Answer:

0.13 ft/min

Step-by-step explanation:

We are given that

$\frac{dV}{dt}=15ft^3/min$

We have to find the increasing rate of change of height of pile when the pile is 12 ft high.

Let d be the diameter of pile

Height of pile=h

d=h

Radius of pile,r= $\frac{d}{2}=\frac{h}{2}$

Volume of pile= $\frac{1}{3}\pi r^2 h=\frac{1}{12}\pi h^3$

$\frac{dV}{dt}=\frac{1}{4}\pi h^2\frac{dh}{dt}$

h=12 ft

Substitute the values

$15=\frac{1}{4}\pi(12)^2\frac{dh}{dt}$

$\frac{dh}{dt}=\frac{15\times 4}{\pi(12)^2}$

$\frac{dh}{dt}=0.13ft/min$
