F(x) = 6x^2 find the inverse
anygoal [31]

Answer:

The inverse is ±sqrt(x/6)

Step-by-step explanation:

Let y = 6x^2

To find the inverse, exchange x and y and then solve for y

Exchange x and y

x = 6y^2

Solve for y

Divide each side by 6

x/6 = 6y^2 /6

x/6 = y^2

Take the square root of each side

±sqrt(x/6) = sqrt(y^2)

±sqrt(x/6) =y

The inverse is ±sqrt(x/6)

Find the values of the measures shown when each value in the data set increases by 25. Mean: 109 Median: 104 Mode: 96 Range: 45
Vikki [24]

Answer:

The new values are as follows:

Mean: 134

Median: 129

Mode: 121

Range=45

Standard Deviation=3.6

Step-by-step explanation:

When a k real number is added to all the elements of the dataset, the new measures of center (mean, median, and mode) are simply found by adding the value k to the previous values. Thus

Mean_{new}=Mean_{old}+k

Here Mean_{old} is 109 and k is 25 thus

Mean_{new}=Mean_{old}+k\\Mean_{new}=109+25\\Mean_{new}=134

Similarly

Median_{new}=Median_{old}+k

Here Median_{old} is 104 and k is 25 thus

Median_{new}=Median_{old}+k\\Median_{new}=104+25\\Median_{new}=129

Also

Mode_{new}=Mode_{old}+k

Here Mode_{old} is 96 and k is 25 thus

Mode_{new}=Mode_{old}+k\\Mode_{new}=96+25\\Mode_{new}=121

When a k real number is added to all the elements of the dataset, the new measures of variation (range and standard deviation) remain the same thus.

Range_{new}=Range_{old}\\Range_{new}=45

Similarly

Standard\ Deviation_{new}=Standard\ Deviation_{old}\\Standard\ Deviation_{new}=3.6

So the new values of mean, median, mode, range, and standard deviation are 134, 129, 121, 45, and 3.6 respectively.

By the congruent supplementary theorem, what can you conclude
valina [46]
Short Answer Only B is true.
Reasoning
A
A is not True. CBG is not equal to DBG. They are supplementary but not equal.

B 
B is correct.

C
CBG = DBF are given as equal. It is not necessarily true that they are supplementary. That would be true only if they were both 90o

D
The two angles are equal, but they are not supplementary. They would be only if both were 90o which is shown not to be the case.

A square has a perimeter of 76 inches. Complete parts (a)-(c) (a) what is the length of each side? Each side has length of?
RideAnS [48]

a - side of the square

4a - the perimeter of a square

76 in - the perimeter of a square

The equation:

4a = 76     <em>divide both sides by 4</em>

a = 19 in.

<h3>Answer: Each side has length 19 inches.</h3>
