Answer: A
Step-by-step explanation:
Since multiplication is the only operation under the radical, you can apply the root to each term. Im not sure if I worded that correctly, but ill hopefully explain correctly.
First we need to take the cubed root of 648. This number doesn't have a perfect root, but it can be simplified. 648 is the same as 216*3, and 216 has a perfect cubed root of 6. So we can bring the 6 outside of the radical
[tex]3x*6\sqrt[3]{3x^4y^8}=18x\sqrt[3]{3x^4y^8}[/tex]
The next step is simplifying the variables, which is the easiest part. Just split them up into multiples of 3, again poor explanation but Ill show what I mean.
[tex]18x\sqrt[3]{3x^3xy^3y^3y^2}[/tex]
The cubed root and the cubed power will cancel and can be brought outside the radical[tex]18x*xy^2\sqrt[3]{2xy^2} =18x^2y^2\sqrt[3]{3xy^2}[/tex]

Find the solution to the system. Write your solution as an ordered pair (x,y) with no spaces, no solution, or infinitely many. 3x-2y=9 and x-y=5
Answer:
(-1,-6)
Step-by-step explanation:
Use substitution
y=x-5
3x-2(x-5)=9
3x-2x+10=9
x=-1
Plug it in
(-1)-y=5
-y=6
y=-6

The equation y = 1125(1.034)" can be used to approximate the number of cell phone users
who live in a certain city over time, where a represents the number of years after 2000.
Which of the following statements is true?
A
the rate of growth is 34%
B
there were 1125 cell phone users in 2000.
С
the rate of decay is 3.4%
D
In the year 2005, there were more than 1350 cell phone users.
Answer: B
there were 1125 cell phone users in 2000.
Step-by-step explanation:
The initial number of cell phone users is the front coefficient that is then multiplied by the growth factor.
So the initial number of cell phone users in 2000 was 1125.

[Formulas are,
[I = P, R, T]
[A = P + I]
[A = P(1 + R times T)
Answer:
$25,689.77
Step-by-step explanation:
[tex]AV=PV(1+i)^n\\AV=24750(1+.0125)^3\\25689.77[/tex]
Answer:
$25,689.775
Step-by-step explanation:
The interest has to be in decimal form. So 1.25/100=0.0125
Plug everything into the equation for compound equation [tex]A=P(1+\frac{r}{t})^{n}^{t}[/tex]
Which is A = 24750 [(1 + 0.0125/1)^(1)(3)]
Type them in a calculator and get A ≈ $25,689.775
***the question says "compounded annually" so the equation for compound interest [tex]A=P(1+\frac{r}{t})^{n}^{t}[/tex] should be used. Your provided formula of A = P(1 + R times T) shouldn't be used here, it is for simple interest but not compound.*** (^_^)

What is the minimum value for the function shown in the graph?
Answer:
2.5
The lowest point on the graph, or the minimum is at f(x)= 2.5
The minimum value of the given periodic function is, 2.5
What are functions?Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).
Vertical line test:-
Whenever we want to check whether a given expression is a function or not we can apply a vertical line test, in this test we check for a single image of x , we are getting a single image or more.
If we get more images then it will not be a function.
For example, let us take, y² = 4ax
y = ±√4ax
For single value of x we get two values of y
Hence, it will not be a function.
Given that,
A periodic function,
Period = 3π
The value of the function is in the range of (2.5, 4.5)
So,
Maximum value = 4.5
Minimum value = 2.5
Thus, the minimum value is 2.5

Solve. 8 - 2d = c 4c + 3d = 2 c=4 d = -6 C=-4 d = 6 C=4 d = 6 C=-4 d = -6
Answer:
c = -4 d = 6
Step-by-step explanation:
8 - 2d = c 4c + 3d = 2
4(8 - 2d) + 3d = 2
32 - 8d + 3d = 2
32 - 5d = 2
-5d = -30
d = 6
8 - 2(6) = c
8 - 12 = -4 = c

Raul came home with $3.00 in his pocket. He had given Rene $1.50 on his way home. Pedro gave him $1.00 that he had borrowed last week. How much money did Raul have at the beginning of the day?
Answer: $3.50
Step-by-step explanation:
He came home with $3.00.
He gave Rene $1.50 which means that $1.50 was deducted from his money.
Pedro gave him $1.00 which added to his money.
Money he had therefore was:
= 3 + 1.50 - 1
= $3.50

Two students, 100 meters apart on the same path, are
walking towards one other. Student A has a speed of 2
meters each second; Student B has a speed of 3 meters each
second. Let's suppose they start to walk to each other when
t=0. How many seconds will it take for the students to bump
into one another? Give your answer to the nearest whole
number.
Answer: 20
Step-by-step explanation:
first you make it into a equation
then you have to make both sides equal the same thing by doing that you figure what t is and t will be your answer
100=2(t)+3(t)
100=2(20)+3(20)
100=40+60
100=100
t=20
It will take 20 seconds for the students to bump into one another.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Student A, has a speed of 2 meters each second;
Student B, has a speed of 3 meters each second.
Let's suppose they start to walk to each other when t=0.
first we will make it into a equation then we have to make both sides equal the same thing by doing that you figure what t is and t will be your answer.
100=2(t)+3(t)
100=2(20)+3(20)
100=40+60
100=100
t=20
Therefore, it will take 20 seconds for the students to bump into one another.
