He spends 45 minutes doing math.

Work - 2.25 time 60 gives the number of minutes he spent total = 135.
135 divided by 3 give the amount of time he worked on math since he          
spent a third of his time on math.

How do you graph f(x)=|x^2-4|?
Citrus2011 [14]
*Hint: When an equation has | it means the absolute value.

Up in the attachment I have provided above is the way that equation should be graphed.

Because the x is squared, it's known that the graph will have a parabola. The -4 is showing the indent it will have.

A tank is full of water. Find the work W required to pump the water out of the spout. (Use 9.8 for g and 3.14 for π. If you ente
OLEGan [10]
To answer the question above, we will have to use some calculus approach to this problem.


<span>volume of sphere = (4/3)(pi)(radius^3) = (4/3)(pi)(9^3) = 972pi </span>
<span>mass = (density)(volume) = (972pi)(1,000) = 972,000pi </span>
<span>force = (mass)(acceleration or gravity here) = (972,000pi)(9.8) = 9,525,600pi </span>
<span>work = (force)(distance) = (9,525,600pi)(4.5) = 42,865,200pi J

What is the equation of a line that passes through point r(−3, 5) and has a slope of 4?
nexus9112 [7]
The equation of any line is:
y=mx+b  m is slope.

We just need to put inside of equation x=(-3) and y=5:
5=4*(-3)+b
17=b

It follows that equation of a line is:
y=4x+17

In a pizza restaurant, you can get a basic pizza with two toppings: cheese and tomato.
poizon [28]

The number of different topping combination illustrates combination

Ross have 6 different topping combination to select from

<h3>The number of different combination</h3>

The given parameters are:

Extra toppings, n = 4

Toppings to select, r = 2

The number of extra topping that Ross can select is then calculated  using the following combination formula

Toppings = nCr

This gives

Toppings = 4C2

Evaluate the combination expression

Toppings = 6

Hence, Ross have 6 different topping combination to select from
