Find f(x) if it is known that f(3k)=3k+7.
Answers
Since f(3k) = 3k+7 (Equation 1)
We have to determine the value of f(x).
That is we have to replace 3k by x,
3k = x
Substituting the value of 3k in equation 1.
So, f(x) = x + 7
Therefore, f(x)=x+7 is the required function.

Find the area of a parallelogram....
Answers
A = bh
Substituting the given values, you have
A = (3x +5)(7x -1)
We presume you want the product multiplied out. Use the distributive property for that.
A = 3x(7x -1) +5(7x -1)
A = 21x² -3x +35x -5
A = 21x² +32x -5
The area of the parallelogram is 21x² +32x -5.
Robin’s scores: 99, 108, 102, 107, 119 Evelyn’s scores: 125, 137, 138, 145, 145 Find and compare the medians of the data sets. Do the medians support your conclusion that Robin is winning the game?
Answers
Robin's scores: 99, 102, 107, 108, 119. Median is 107.
Evelyn's scores: 125, 137, 138, 145, 145. Median is 138.
The median from Evelyn's scores is greater than the median from Robin's. Therefore, the medians do NOT support the conclusion that Robin is winning the game.
Answer:
The median score for Robin is 107. The Median Score of Evelyn is 138. The medians are the same as the means, so the same conclusion that Robin is winning will be drawn.

The big bend national park covers 800,000 acres. Brazos Bend state park covers about 5,000 acres. About how many more acres does Big Bend National Park cover then Brazos Bend state park?
Answers
this but okay....
Big Bend National Park is larger by approximately 795,000 acres than Brazos Bend State Park. This figure was obtained by subtracting the area of the Brazos Bend State Park from the area of the Big Bend National Park.
Explanation:The Big Bend National Park and the Brazos Bend State Park have a substantial difference in size. You can calculate this size difference by performing a simple subtraction operation. In this case, the size of the Big Bend National Park is 800,000 acres, whereas Brazos Bend State Park covers about 5,000 acres. By subtracting the size of Brazos Bend State Park from the size of the Big Bend National Park, we will get about 795,000 acres, which represents the size difference.
So, the formula would appear as follows:
800,000 acres (Big Bend National Park) - 5,000 acres (Brazos Bend State Park) = 795,000 acres difference.

"The functions have the same rate of change" is wrong because as we can see, the table goes up by 10, however, the graph goes up by 15
"Both functions are the same" is also wrong, we already proved they have a different slope, how could they possibly be the same?
"The rate of change for Tour 1 is greater" is also wrong because tour 2 goes by 15, which is greater than 10.
"The functions have the same initial value is correct because as we can see on the graph(tour 2), the y-intercept is 35, using the slope on the tab;e(tour 1) we can calculate that when x is 0, the y-value is 35, which means both of the tours has a y-intercept of 35, therefore, this is the correct choice
Explanation: Alright let's do answer of elimination. It cannot be "Both functions are the same" Due to the fact that for one person in Tour 1 is 45 dollars while for Tour 2 is 50. It cannot be "The functions have the same initial value. Since for initial value it's kind of like a constant. For example for 1 person it would be 20 dollars for 2 it would be 40 and so on. It cannot be the last one since rate of change is obviously different. I don't think I have to go into that.

Solve the equation (x-5)1/2+5=2
Answers
((x-5) ^ (1/2)) + 5 = 2
Clearing x we have:
(x-5) ^ (1/2) = 2-5
(x-5) ^ (1/2) = -3
x-5 = root (-3)
x-5 = i * root (3)
x = 5 + i * root (3)
Answer:
The value of x is given by:
x = 5 + i * root (3)
(x - 5)1/2 + 5 - 5 = 2 - 5
(x - 5)1/2 = -3
1/2x - 2.5 = -3
1/2x - 2.5 + 2.5 = -3 + 2.5

Answers
Amount used for dress= 40% of a
amount left =60% of a
amount used for shoe= 1/5*60a/100=3a/25
left=60a/100-12a/100=48a/100
=>48a/100-60=132
=>a=192*100/49=400
She had $400 at first.
Hope I helped, good luck.
Dress = 40% x = 0.4x
Amount left = x - 0.4x = 0.6x
Shoes = 1/5 x 0.6x = 0.12x
Amount left = 0.6x - 0.12x = 0.48x
Donated $60 and had $132 left:
⇒ 0.48x - 60 = 132
Solve x:
0.48x - 60 = 132
0.48x = 192
x = $400

what does the varience tell you?
Answers
V = s^2
where V = variance and s = standard deviation
So the variance can also be used to determine how grouped or spread out the data values are
------------------------------------------
The z score tells us where this score is located in terms of the group. If the z score is positive, then it is above the mean. If the z score is negative, then it is below the mean. The further the z score is from zero, the further the raw score is from the mean. A score of z = 0 is right at the mean.
