What is the cube root of 216x^9y^18 ?
A: 4x^3y^6
B: 6x^3y^6
C: 72x^6y^15
D: 213x^6y^15
Answers
[tex]4 {x}^{3} {y}^{6} [/tex]
OPTION A
Answer:
option B
Step-by-step explanation:
Cube root of x means [tex]x^{\frac{1}{3}[/tex]
Formulas used :
[tex](a^x)^y = a^{xy}[/tex]
[tex](b^3)^{\frac{1}{3}} = b[/tex]
Therefore cube root of :
[tex](216 x^9 y^{18})^{\frac{1}{3}} = (6^3 \times (x^3)^3 \times (y^6)^3)^{\frac{1}{3}}[/tex]
[tex]= (6^3)^{\frac{1}{3}} \times ((x^3)^3)^{\frac{1}{3}} \times ((y^6)^3)^{\frac{1}{3}}[/tex]
[tex]= 6 \times x^3 \times y^6[/tex]
[tex]=6x^3y^6[/tex]

Kwame and Ama shared an amount of money in the ratio 5:4 respectively. If Kwame had GHC 9.00, how much did they share?
Answers
Answer:
They shared GHC16.2
Step-by-step explanation:
Here, we want to get the amount shared
Let us call the amount x
Total ratio is 5 + 4 = 9
Kwame had GHC 9
Thus;
5/9 * x = 9
5 * x = 9 * 9
5x = 81

2) Find the remainder when x3 + x2 - 20 is divided by
(x + 2) by using remainder theorem.
{ANS: R = -24}
Answers
Answer:
Remainder = –24
Step-by-step explanation:
x³ + x² – 20 divide by x + 2
We can obtain the remainder when
x³ + x² – 20 is divided by x + 2 using the remainder theorem as follow:
We'll begin by calculating the value of x from x + 2. This is illustrated below:
x + 2 = 0
Collect like terms
x = 0 – 2
x = –2
Finally, we shall determine the remainder by substituting –2 for x in
x³ + x² – 20. This is illustrated below:
x³ + x² – 20
x = –2
Remainder = (–2)³ + (–2)² – 20
Remainder = –8 + 4 – 20
Remainder = –24
Therefore, the ramainder when
x³ + x² – 20 is divided by x + 2 is –24

The image of a parabolic lens is projected onto a graph. The image crosses the x-axis at –2 and 3. The point (–1, 2) is also on the parabola. Which equation can be used to model the image of the lens?
y = (x – 2)(x + 3)
y = (x – 2)(x + 3)
y = (x + 2)(x – 3)
y = (x + 2)(x – 3)
Answers
Given:
The image of a lens crosses the x-axis at –2 and 3.
The point (–1, 2) is also on the parabola.
To find:
The equation that can be used to model the image of the lens.
Solution:
If the graph of polynomial intersect the x-axis at c, then (x-c) is a factor of the polynomial.
It is given that the image of a lens crosses the x-axis at –2 and 3. It means (x+2) and (x-3) are factors of the function.
So, the equation of the parabola is:
[tex]y=k(x+2)(x-3)[/tex] ...(i)
Where, k is a constant.
It is given that the point (–1, 2) is also on the parabola. It means the equation of the parabola must be satisfy by the point (-1,2).
Putting [tex]x=-1, y=2[/tex] in (i), we get
[tex]2=k(-1+2)(-1-3)[/tex]
[tex]2=k(1)(-4)[/tex]
[tex]2=-4k[/tex]
Divide both sides by -4.
[tex]\dfrac{2}{-4}=k[/tex]
[tex]-\dfrac{1}{2}=k[/tex]
Putting [tex]k=-\dfrac{1}{2}[/tex] in (i), we get
[tex]y=-\dfrac{1}{2}(x+2)(x-3)[/tex]
Therefore, the required equation of the parabola is [tex]y=-\dfrac{1}{2}(x+2)(x-3)[/tex].

Pat bought 6 shirts that were all the same price. He used a traveler's
check for $25, and then paid the difference of $86. What was the
price of each shirt?
Answers
Answer:
Each shirt costs $18.50
Step-by-step explanation:
Questions such as these usually involve quite simple calculations, but they are important in being able to convert a scenario described in words into math calculations.
First, read the information carefully and then summarize what you are given in short sentences. Pat bought 6 shirts. He paid using a check and cash.
The total amount paid was $ 25 + $ 86 = $ 111
The shirts all cost the same price.
The cost of each shirt was: 111 ÷ 6 = $ 18.50
Answer:
Each shirt was 18.50
Step-by-step explanation:
The total cost of the 6 shirts was 25+86 = 111
Divide the total by 6 to find the cost of each shirt
111/6 =18.5
Each shirt was 18.50

Round the decimal to the nearest tenth.
Answers
(2.75 x 10⁵ ) / (2.25 x 10² )

= 1.2 x 10³ times .
(That's 1,200 times as many.)
I hope this helps!
Answer:
1221.2 times more
Step-by-step explanation:
number of bacteria last week = [tex]2.25*10^2[/tex]
= [tex]2.25*100[/tex]
= [tex]225[/tex]
number of bacteria this week = [tex]2.75*10^5[/tex]
= [tex]2.75*100000[/tex]
= [tex]275000[/tex]
[tex]275000 - 225 = 274775[/tex]
[tex]274775 / 225 = 1221.2[/tex]
What are the characteristics of the graph of the inequality x ≥ -2? The ray will move to the left. The ray will move to the right. It will use an open circle. It will use a closed circle.(multiple answers)
Answers
Answer:
Step-by-step explanation:
The inequality x ≥ -2 is graphed on a number line. -2 is the smallest possible value. All subsequent values are larger and therefore lie to the right of -2.
Thus, the following are true:
1. The ray will move to the right (because x begins at -2 and increases, which means moving to the right on the number line).
2. It will use a closed circle (because x = -2 is part of the solution set).
Answer: The ray will move to the right and it will be a closed circle.

Answers
Answer:
142
Step-by-step explanation:
angle <3 is supplementary to 5x + 3
5x + 3 + 21x - 5 = 180 (because two angles are supplementary as well)
26x - 2 = 180 add 2 to both sides
26x = 182 divide both sides by 26
x = 7
<3 + 5x + 3 = 180 replace x with 7 and rewrite equation
<3 + 38 = 180 subtract 38 from both sides
<3 = 142

Answer:
6.)
The answer is 63 inches because this value is closer to the mean and while the data is positively skewed (as in the mean is greater than the median) it's not by that much.
7.)
This would mean that the data is symmetric. By this, I mean that there would have to be an equal amount of data on either side of the mean. For example, for every entry 2 units below from the mean there must be one 2 units above the mean and so on. There would also have to be many entries on the mean/median (so that it would also be the mode)
8.)
We can observe that there are no real outliers that would heavily influence the data and so we can just take the mean
the mean of student A is: (68+72+73+67)/4= 70
The mean of student B is: (74+73+73+74)/4=73.5
We can see that student A, on average, is closer to 70 than student B and can therefore conclude that student A is more percise
