Which is equivalent to 4 square root 9^1/2x? Choices are: A) 9^2x B) 9^1/8x C) square root 9^x D) 6 square root 9^x

Answers

Answer 1
it should be B im not sure
Answer 2

Answer: The correct option is B.

Explanation:

The given expression is,

[tex]\sqrt[4]{9^{\frac{1}{2}}}x[/tex]

Use the property of radical expression [tex]\sqrt[n]{x} =x^{\frac{1}{n} }[/tex].

[tex]\sqrt[4]{9^{\frac{1}{2}}}x=(9^{\frac{1}{2})^{\frac{1}{4}}}x[/tex]

Use the property, [tex](x^m)^n=x^{mn}[/tex]

[tex]\sqrt[4]{9^{\frac{1}{2}}}x=9^{\frac{1}{2\times 4}x[/tex]

[tex]\sqrt[4]{9^{\frac{1}{2}}}x=9^{\frac{1}{8}x[/tex]

Therefore, the correct option is B.

Which function goes with this graph?

Answers

From the given points on the graph we can find which function represents this graph.

A point on the graph is (3, 1). This means if we substitute x = 3 the answer must be 1.

The property of log is that [tex] log_{a}(a)=1[/tex]

This suggests, if the base of log is equal to the number for which we are finding the log, the answer must be 1.

So, in this case we have:

[tex]log_{a}(3)=1 [/tex]

Since the answer is 1, the base of log must be 3.

In the given options, only option 3rd is with base 3.

So, the correct answer is option 3.

Susan gets paid x dollars per hour. After 40 hours she gets paid time and a half (1.5 times her normal hourly pay). Last month she worked 52 hours each week and earned $696 each week. How much does Susan get paid per hour?

Answers

She gets paid $12 per hour.

Let x be the amount she gets paid per hour.  Working 40 hours would then be represented by 40x.

Anything over 40 hours earns her 1.5 her normal rate, or 1.5x.  Since she works 52 hours, this means 52-40=12 hours of overtime at 1.5x:
12(1.5x) = 18x

Together, she earned 696:
40x+18x = 696

Combining like terms,
58x = 696

Divide both sides by 58:
58x/58 = 696/58
x = 12

city b : 
67+73+75+73+69+78+76+74+72+74 = 731

A college entry exam has 38 questions worth 200 points. The test consists of multiple-choice questions, x, worth 4 points each and essay questions, y, worth 10 points each. Which system of equations can be solved to find the number of multiple-choice questions on the test?

Answers

A system of equations is a set of equations to be solved by elimination or substitution.

There are no options listed in the question to choose from, but the equations should look like the following:

x= # multiple choice questions
y= # essay questions

QUANTITY EQUATION:
x + y= 38

VALUE EQUATION:
4x + 10y= 200

If we solved these two equations by elimination or substitution, we would find the number of multiple choice (x) and the number of essay (y) questions on the test.


ANSWER: x + y= 38; 4x + 10y= 200

Hope this helps! :)

Answer:

Let's use the variables x and y to represent the number of multiple-choice and essay questions on the test, respectively.

The total number of questions is 38, so we can write:

x + y = 38

The total number of points is 200, so we can write:

4x + 10y = 200

This gives us a system of equations:

x + y = 38

4x + 10y = 200

We can solve this system of equations to find the number of multiple-choice questions on the test.

which of the following functions is continuous between x=-3 and x=0? choices on attachment

Answers

When we say that a function is continuous between x = -3 and x = 0 it means that it exists for all values of x in between -3 and 0. Let's take a look at each choice individually:

A: f(x) = (-x + 1)/(x + 2)
Now we don't actually need to know what the graph of this function looks like to see which values it is continuous for, instead we should look at which values of x will make this function undefined - in this case that would be x = -2. The reasoning behind this is that a number divided by 0 would be undefined, so when we search for which value of x would make the denominator of the equation 0, we get:
x + 2 = 0
x = -2
Since x = -2 is within the interval [-3, 0] we cannot say the function is continuous over this interval

B: f(x) = -2/(x + 1)
Using the same method as above we get:
x + 1 = 0
x = -1
x = -1 is again within the interval [-3, 0] and so the function is not continuous within this interval

C: f(x) = 3x/(x - 2)
x - 2 = 0
x = 2
x = 2 is outside the interval of [-3, 0] and so the function is continuous within this interval and C is the correct answer.

Just for the sake of it however we can look at D as well:
D: f(x) = 1/(2x + 1)
2x + 1 = 0
x = -1/2
-1/2 is within [-3, 0] and so D is not continuous over this interval

A grocery store has three locations: Central, North, and South. The grocery store counted the number of cantaloupes sold at each of the three locations each day for a month. The table shows the mean and the mean absolute deviation of the number of cantaloupes sold each day. Which statements are correct? Select each correct answer.
The number of cantaloupes sold at North and South varied about the same amount.
The number of cantaloupes sold at Central varied less than did the number sold at North.
The number of cantaloupes sold at Central and South varied about the same amount.
The number of cantaloupes sold at Central varied more than did the number sold at South.
Store location Mean number of sales MAD Central 45 4.1 North 47 5.7 South 29 5.9

Answers

The correct option is The number of cantaloupes sold at Central varied less than did the number sold at North.

What is the mean absolute deviation?

The means absolute deviation is the average distance of each of the data points about the mean.

The below-given table shows the data of the three different stores.

Store location   Mean number of sales     MAD

Central                            45                               4.1

North                               47                               5.7

South                              29                               5.9

As we know that the mean absolute deviation shows as the average of the difference in the mean data that can occur. Therefore, it shows us the amount by which the data can deviate from its mean.

Now, if we look at the option, the only option that is correct about the given data is "The number of cantaloupes sold at Central varied less than did the number sold at North".

The statement holds true because the Mean absolute deviation for the store in the center is least, therefore, it varies the least from all the given options.

Hence, the correct option is The number of cantaloupes sold at Central varied less than did the number sold at North.

Find the Distance, d, across the lake

Answers

The answer is 11.25 ft. 
You have to use similar figures to work this out.
15 ft / 8 ft has to equal d ft  / 6 ft
So, you divide 15 by 8, which equals 1.875
You then times 1.875 by 6 = 11.25


The Distance, d, across the lake is 26.25 feet.

Similar Triangles

When two triangles have all the corresponding angles equal to each other, then their sides are in a ratio.

Given to us,

AB = 8 feet,

BC = 15 feet,

BP = 6 feet,

PQ = d,

AP = AB + BP = 8 + 6 = 14 feet

In the figure, [tex]\triangle ABC \sim \triangle APQ[/tex]

[tex]\dfrac{BC}{AB}=\dfrac{PQ}{AP}[/tex]

[tex]\dfrac{15}{8}=\dfrac{d}{14}[/tex]

[tex]d = \dfrac{15\times 14}{8}[/tex]

[tex]d = 26.25[/tex]

Hence, the Distance, d, across the lake is 26.25 feet.
