Answer:
(x^4/3x^2/3)^1/3
using the power of powers rule (multiply the exponents)
x^(4/3*1/3) x^(2/3* 1/3)
x^ (4/9) ( x^ 2/9)
when multiply exponents, add
x^ (4/9 + 2/9)
x^ (6/9)
x^ (2/3)

a thousand dollars is left in a credit union drawing 7% compounded monthly. what is the balance at the end of 10 years
Answer:
$9400
Step-by-step explanation:
You start with $1000 and get 7% more every month.
7% of 1000 is 70 so that means $70 is added to the credit union each month.
So you add $70 dollar to $1000 for every month there is which would be 12 months timers the ten years:
1000 + (70 x 12 x 10) = 9400
11. Maria's age is 3 years more than twice George's age. Which expression represents George's age in terms of Maria's?
Answer:
C
Step-by-step explanation:
Okay, the catch of this question is that they do a very good job of explaining Maria's age in terms of George's age, but they leave George's age in terms of Maria's all up to you.
First start off by doing an expression of what they explicitly give you. Maria's age in terms of George's age.
Let's use variables g, representing George's age and m representing Maria's age
m = 2g + 3
Okay, this is all dandy and all, but they ask us for George's age in terms of Maria's, so we need to isolate for g.
subtract the 3 from both sides, like so:
m - 3 = 2g
then divide 2 from both sides: (remember we're dividing the whole thing)
(m-3)/2 = g
Now we have an expression for George's age in terms of Maria's.
g = (m-3)/2 or [tex]g = \frac{m-3}{2}[/tex]
The answer that gives us this, is C.

A bag contains 2 red marbles, 7 blue marbles and 5 green marbles. If two marbles are
drawn out of the bag, what is the exact probability that both marbles drawn will be
blue?
Answer:
1/2
Step-by-step explanation:
There are :-
⇒ 2 red marbles
⇒ 7 blue marbles
⇒ 5 green marbles
Probability (Blue)
= No. of blue marbles / No. of total marbles= 7 / (2 + 7 + 5)= 7/14= 1/2Which graph represents an exponential function?
Answer:The function that represents an exponential function is the 4th graph and it can be modeled as y = aeᵇˣ.
What are exponential functions?
The exponential functions are written in the form of y = aeᵇˣ, where the output y increases exponentially for the input x.
In order to find the graph that represents an exponential function, we will discuss each of the following graphs,
For the 1st graph, (Black),
In the first graph, the graph is of a parabola, and the function which represents this kind of graph is a quadratic equation, therefore, this graph represents a parabolic equation. It is given by the function,
y=ax²+bx+c or y=a(x-h)²+k
For the 2nd graph, (Red),
In the second graph, the graph represented is the graph of a reciprocal function, the function that can be represented by the graph,
y=a/x + b
For the 3rd graph, (Blue),
In the third graph, the graph represented is the graph of root function, it can be modeled as,
y = a+√(x+b)
For the 4th graph, (Green),
In the fourth graph, the graph represented is the graph of an exponential function, and it can be modeled as,
y = aeᵇˣ
Hence, the function that represents an exponential function is the 4th graph and it can be modeled as y = aeᵇˣ.

Giving brainliest to whoever’s right
Answer:
Bottom Right graph
Step-by-step explanation:
The quation asks what slope of the graph represents how many people are served per hour. If 600 people are served in 10 hours, you divide 600 by 10 to see how many people are served per hour. In this case it is 60 people per hour. Then you find the graph that shows 60 more people served per hour. Hope this helps.

A study was designed to investigate the effects of two variables(1) a student's level of mathematical anxiety and (2) teaching methodon a student's achievement in a mathematics course. Students who had a low level of mathematical anxiety were taught using the traditional expository method. These students obtained a mean score of 440 with a standard deviation of on a standardized test. Assuming no information concerning the shape of the distribution is known, what percentage of the students scored between 360 and 520 ?
Using Chebyshev's Theorem, considering a standard deviation of 40, we have that at least 75% of the students scored between 360 and 520.
What does Chebyshev’s Theorem state?When we have no information about the population distribution, Chebyshev's Theorem is used. It states that:
At least 75% of the measures are within 2 standard deviations of the mean.At least 89% of the measures are within 3 standard deviations of the mean.An in general terms, the percentage of measures within k standard deviations of the mean is given by [tex]100(1 - \frac{1}{k^{2}})[/tex].In this problem, considering a standard deviation of 40, we have that:
440 - 2 x 40 = 360.
440 + 2 x 30 = 520.
Within 2 standard deviations of the mean, no information about the distribution, hence, at least 75% of the students scored between 360 and 520.

The ratio of blue jays to Robin's was 6 to 7. If there were 84 Robins, how many blue jays were there?
Answer:
72
Step-by-step explanation:
Since the ratio of blue jays to robin's was 6 to 7 then if there were 84 robins how many blue jays were there.
6 to 7 can also be express as 6/7
Thus, we can set up a proportion
6/7 = x/84
Now, we have to solve for x
x = 72
Hence, if there were 84 robin there would be 72 blue jays.

EXPLAIN AND SOLVE THE EQUATION
Answer:
1st answer: 61000+(X-1) x 700
2nd answer: 64500
Step-by-step explanation:
Since it says the population increases linearly, which means by the same amount, it is an arithmetic progression. So the formula to find a term in arithmetic progression is [tex]T_{n}[/tex]=a + ( n - 1 ) x d , where a is the first term, n is number of terms, and d is common difference. So now just put the values in the equation, where 61000 is a, x is n and d is 700. To find second answer put 6 in place of n as it says from 2003 to 2009 which is 6 years later.

What is the dividend yield on Stock A that sells at
$15/share, when Company A pays a quarterly
dividend of $0.20 per share?
dividend yield = [?] %
Give your answer as a percent rounded to the
nearest tenth
Hint: Dividend Yield
annual dividend
share price
Answer:
5.3%
Step-by-step explanation:
The annual dividend is 4 times the quarterly dividend, so is $0.80 per share. The yield is the ratio of that to the share price:
yield = $0.80/$15.00 ≈ 0.05333... ≈ 5.3%
The dividend yield is 5.3%.
In shop class, Adriana makes a pyramid with a 4-inch square base and a height of 6 inches. She then cuts the pyramid vertically in half as shown. What is the area of each cut surface?
The area of the square pyramid is the amount of space on it
The total surface area of each cut surface is 33.28 square inches
How to determine the surface area of each cut surface?The given parameters are:
Base (b) = 4 cm
Height (h) = 6 cm
Start by calculating the slant height (l) using:
l = √((4/2)^2 + 6^2)
l = 6.32
The lateral surface area is calculated using:
L = 2bl
So, we have:
L = 2 * 4 * 6.32
Evaluate the product
L = 50.56
The total surface area is calculated using:
T = L + b^2
So, we have:
T = 50.56 + 4^2
Evaluate
T = 66.56
Divide the total surface area by 2
T/2 = 33.28
Hence, the total surface area of each cut surface is 33.28 square inches

You COULD DIEEEE ._.
Step-by-step explanation:
Solve each pair of simultaneous equations giving both solutions. You need to multiply both equations by suitable numbers before adding \subtracting to eliminate.
a) 6x - 7y = 9
3x + 2y = 54
b) 4x - 5y = 12
2x - 3y = 8
c) 4x - 2y = 28
3x + 3y = 12
please work it out and clear. who ever answer give them brainlest answer
Answer:
a) x = 12 y = 9
b) x = -2 y = -4
c) x = 6 y = -2
Step-by-step explanation:
a)
Equation 1: 6x - 7y = 9
Equation 2: 3x + 2y = 54
Multiply Equation 2 by 2:
⇒ 6x + 4y = 108
Subtract equations:
6x + 4y = 108
- 6x - 7y = 9
11y = 99
Divide both sides by 11:
⇒ y = 9
Substitute found value of y into Equation 1 and solve for x:
⇒ 6x - 7(9) = 9
⇒ 6x - 63 = 9
⇒ 6x = 72
⇒ x = 12
---------------------------------------------------------------------------------------------------
b)
Equation 1: 4x - 5y = 12
Equation 2: 2x - 3y = 8
Multiply Equation 2 by 2:
⇒ 4x - 6y = 16
Subtract equations:
4x - 6y = 16
- 4x - 5y = 12
-y = 4
Divide both sides by -1:
⇒ y = -4
Substitute found value of y into Equation 1 and solve for x:
⇒ 4x - 5(-4) = 12
⇒ 4x + 20 = 12
⇒ 4x = -8
⇒ x = -2
---------------------------------------------------------------------------------------------------
c)
Equation 1: 4x - 2y = 28
Equation 2: 3x + 3y = 12
Multiply Equation 1 by 3:
⇒ 12x - 6y = 84
Multiply Equation 2 by 4:
⇒ 12x + 12y = 48
Subtract equations:
12x - 6y = 84
- 12x + 12y = 48
-18y = 36
Divide both sides by -18:
⇒ y = -2
Substitute found value of y into Equation 1 and solve for x:
⇒ 4x - 2(-2) = 28
⇒ 4x + 4 = 28
⇒ 4x = 24
⇒ x = 6
