Answer:
- 104
Step-by-step explanation:
Assuming the question is to evaluate the expression.
Given
- 3m² + 4n - p ← substitute given values for m, n and p
= - 3(- 6)² + 4(2) - 4
= - 3(36) + 8 - 4
= - 108 + 4
= - 104

An oil tank has to be drained for maintenance. The tank is shaped like a cylinder that is 4 ft long with a diameter of 2.2 ft. Suppose oil is drained at a
rate of 1.5 per minute. If the tank starts completely full, how many minutes will it take to empty the tank?
Use the value 3.14 for, and round your answer to the nearest minute. Do not round any intermediate computations.
Answer:
[tex]8\:\mathrm{minutes}[/tex]
Step-by-step explanation:
The volume of a cylinder is given as:
[tex]r^2\cdot\pi\cdot h[/tex]
Since the diameter is [tex]2.2[/tex], the radius is [tex]\frac{2.2}{2}=1.1[/tex].
Therefore, the volume of this cylinder is:
[tex]1.1^2\cdot 3.14\cdot 4=15.1976\:\mathrm{ft^3}[/tex], using [tex]\pi=3.14[/tex] as requested in the problem.
Since the tank is emptied at a constant rate of [tex]1.5\:\mathrm{ft^3\:per\:minute}[/tex], it will take
[tex]\frac{15.1976}{1.5}=7.5988=\fbox{$8\:\mathrm{minutes}$}[/tex] to empty the tank.
Hamda and Layla get paid per project.
Hamda is paid a project fee of AED 25 plus AED 10.50 per hour.
Layla is paid a project fee of AED 18 plus AED 14.25 per hour.
Write an expression to represent how much a company will pay to hire both to work the same number of hours on a project.
Show your steps
Answer:
[tex]Company: 43 + 24.75h[/tex]
Step-by-step explanation:
Given
Hamda:
[tex]Project\ Fee = 25[/tex]
[tex]Hourly\ Rate = 10.50[/tex]
Layla:
[tex]Project\ Fee = 18[/tex]
[tex]Hourly\ Rate = 14.25[/tex]
Required
Derive an expression for total pay
Represent the number of hours with h.
For Hamda and Layla, their pay for h hours is:
[tex]Pay = Project\ Fee + Hourly\ Rate * h[/tex]
For Hamda, we have:
[tex]Hamda : 25 + 10.50 * h[/tex]
[tex]Hamda : 25 + 10.50 h[/tex]
For Layla, we have:
[tex]Layla: 18 + 14.25 * h[/tex]
[tex]Layla: 18 + 14.25 h[/tex]
For h hours, the company will pay:
[tex]Company: Hamda + Layla[/tex]
[tex]Company: 25 + 10.50h + 18 + 14.25h[/tex]
Collect like terms
[tex]Company: 25 + 18 + 10.50h + 14.25h[/tex]
[tex]Company: 43 + 24.75h[/tex]

Given: h(t) = 2t - 5,
Solve for the following.
Part A. h(-4) = ?
Part B. h(t) = 23, then t = ?
I
Part C. h(13) = ?
Part D. h(t) = -33, then t = ?
Please show your work
Step-by-step explanation:
Part A:
h(-4) = 2(-4) - 5 = -13.Part B:
h(t) = 23, 2t - 5 = 23, 2t = 28, t = 14.Part C:
h(13) = 2(13) - 5 = 21.Part D:
h(t) = -33, 2t - 5 = -33, 2t = -28, t = -14.The value of h(-4) for the given function is -13.
The given function is h(t) = 2t - 5.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Part A:
Put t=-4 in the given function, we get
h(-4) = 2(-4)-5
= -8-5
= -13
Part B:
Substitute h(t)=23 in the given function, we get
23=2t-5
⇒2t=23+5
⇒2t=28
⇒t=14
Part C:
Put t=13 in the given function, we get
h(13)=2(13)-5
= 26-5
= 21
Substitute h(t)=-33 in the given function, we get
-33=2t-5
⇒2t=-33+5
⇒2t=-28
⇒t=-14
Therefore, the value of h(-4) for the given function is -13.

If CE = 3x - 10 and EA = 2x + 1, then CA=
Answer:
46
Step-by-step explanation:
First you need to solve.. So put 3x - 10 and 2x + 1 together as one equation.
It should look like this:
3x - 10 = 2x + 1
Now you just need to solve it.
1) First you add 10 on both sides.
3x - 10 = 2x + 1
+ 10 = + 10
------------------------
3x = 2x + 11
2) Then you subtract 2x on both sides.
3x = 2x + 11
- 2x =- 2x + 11
-------------------------
x = 11
3) Now you plug in 11 for x.
3x - 10 = 2x + 1
Like this:
3(11) - 10 = 2(11) + 1
33 - 10 = 22 + 1
23 =23
So C to E and E to A = 23
To get from C to A just add 23 + 23 which is 46. And that is ur answer.

In his 2011 State of the Union Address, President Barack Obama said:
"To attract new businesses to our shores, we need the fastest, most reliable ways to move people, goods, and information—from high-speed rail to high-speed Internet. Our infrastructure used to be the best, but our lead has slipped. The jobs created by the transcontinental railroad & the Interstate Highway System didn't just come from laying down track or pavement. They came from businesses that opened near a town's new train station or the new off-ramp.
We've begun rebuilding for the 21st century. And tonight, I'm proposing that we redouble those efforts. We'll put more Americans to work repairing crumbling roads and bridges. Within 25 years, our goal is to give 80% of Americans access to high-speed rail. Within the next five years, we'll make it possible for businesses to deploy the next generation of high-speed wireless coverage to 98% of all Americans. This isn't just about faster Internet or fewer dropped calls. It's about connecting every part of America to the digital age."

Apply l'Hopital's rule:

where
