Answer:
3r^2 /2
Step-by-step explanation:
r^3 cancels out r in the denominator remaining with r^2 in the numerator.
so 3r^2/2
= 3r^2 /2
Answer:
solving the expression [tex]\frac{3r^3}{2r}[/tex] we get [tex]\mathbf{\frac{3}{2}r^2}[/tex]
Step-by-step explanation:
We need to solve the expression: [tex]\frac{3r^3}{2r}[/tex]
For solving exponents in the fraction we can use the exponent rule:[tex]\frac{a^m}{a^n}=a^{m-n}[/tex]
Applying the above rule and solving:
[tex]\frac{3r^3}{2r}\\=\frac{3}{2}r^{3-1}\\\\=\frac{3}{2}r^2[/tex]
So, solving the expression [tex]\frac{3r^3}{2r}[/tex] we get [tex]\mathbf{\frac{3}{2}r^2}[/tex]

How are the ordered pair (4,9) and (4,-9) similar, and how are they different?
Answer:
Both of the points are in the same x-axis (which is 4). However, they are different because one of them is shifted 9 units up and the other one is shifted 9 units down (their y-axis are different). Their quadrants are also different since (4,9) is at the first quadrant, while (4,-9) is at the fourth quadrant.

PRE CALC QUESTION, PLEASE HELP
how much pressure is needed in ground based water pipes to pump water up to the restaurant on the top floor of the world trade center, 410m above the ground.
The pressure needed to pump water up to the restaurant on the top floor is 4018000 N/m².
What is pressure?Pressure can be defined as the ratio of force to area of an object.
To calculate the pressure needed, we use the formula below.
Formula:
P = Dgh............... Equation 1Where:
P = Pressure D = Density of waterg = Acceleration due to gravityh = Height.From the question,
Given:
h = 410 mD = 1000 kg/m³g = 9.8 m/s²Substitute these values into equation 1
P = 410×1000×9.8P = 4018000 N/m²Hence, the pressure needed to pump water up to the restaurant on the top floor is 4018000 N/m².

The graph of this function is a parabola which opens upward.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
We have been given the following function:
g(x) = (x + 4)(x − 9)
The graph of this function is a parabola which opens upward and whose x-intercepts are:
x + 4 = 0
x = -4
x - 9= 0
x = 9
On the other hand, the y-intercept will be:
g(x) = (x + 4)(x − 9)
g(x) = (0 + 4) (0 − 9)
g(x) = -36
Hence, the graph of this parabola is attached below.

To make widgets, Buford rents a shop for $2950 a month and calculates the materials for each widget are $38. How many widgets can he make in a month for $12,000?
Answer: 238 widgets
Step-by-step explanation:
12000$ - 2950$ = 9050$
9050$/38$≈238 (widgets)
The required, Buford can make at most 238 widgets in a month for $12,000.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
Let's first calculate the total cost of making x widgets in a month.
The cost of materials for each widget is $38, so the total cost of materials for x widgets is 38x.
In addition to the cost of materials, Buford has to pay $2950 per month for rent. So the total cost of making x widgets in a month is,
C(x) = 2950 + 38x
We want to know how many widgets Buford can make in a month for $12,000. So we want to solve the equation,
C(x) = 12000
Substituting the expression for C(x), we get:
2950 + 38x = 12000
38x = 9050
x = 238.16
Buford cannot make a fraction of a widget, so he can make at most 238 widgets in a month for $12,000.
