can u pls show me how to do it and answer

Answer:

228

Step-by-step explanation:

76*3=228

f(x) as given has no inverse. We see that, for instance, f(1) = f(7) = 32; that is, two different values of x give the same value of f(x), so f is not one-to-one.

We can however restrict the domain over which f is defined to extract an invertible function. One such choice would be to restrict to the interval x ≥ 4, which I'll demonstrate below.

Recall the definition of function inverse:

f(f^(-1)(x)) = x

Then for this function, we have

3 (f^(-1)(x) - 4)² + 5 = x

3 (f^(-1)(x) - 4)² = x - 5

(f^(-1)(x) - 4)² = (x - 5)/3

√((f^(-1)(x) - 4)²)= √((x - 5)/3)

For all x, √(x²) = |x|. Then √((f^(-1)(x) - 4)²) = |f^(-1)(x) - 4|, but by restricting x ≥ 4, or x - 4 ≥ 0, we have the condition that f^(-1)(x) - 4 ≥ 0, and so by definition (of the absolute value function) the absolute value reduces to the positive case. In short, we end up with

f^(-1)(x) - 4 = √((x - 5)/3)

and hence the inverse

f^(-1)(x) = √((x - 5)/3) + 4

Answer:

it would equal 12x + 12

Answer:

D.

Step-by-step explanation:

Quadrilateral: 4 sides

Pentagon: 5 sides

Hexagon: 6 sides

Now we expect 7 sides.

Answer: D.

Answer:

D

Step-by-step explanation:

The first shape has 4 vertices (quadrilateral), the second has 5 vertices (pentagon), the third shape has 6 vertices (hexagon) so the fourth would most likely have 7 vertices (heptagon).

Hope this help!

Answer:

Median:20

mean:21

mode:15

Hello there! :)

To find the mean, we must add all the terms in the dataset and then divide by how many there are.

15+20+15+30+25=105

105÷5=21

So the mean is 21.

To find the median, we must find the number in the middle.

First, arrange the terms from least to greatest:

15, 15, 20, 25, 30

Now, we can see than 20 is the median.

To find the mode, we must find the number that is seen most often in the dataset.

15 is seen twice

20 is seen once

25 is seen once

30 is seen once

So 15 is the mode.

Hope this helps you!

Answer: third part of the batch 1 :1/2 gallon of yellow Second batch part 1: 4

Step-by-step explanation:

third part of the batch 1 explanation

Since we know that there should be the same amount of yellow and green (they are each 1/4 of the recipe) and there is a half a gallon of green there should same amount the yellow. Hence, the answer is 1/2 gallon.

For the second part of the question, we know that 2 gallons is 1/4 of the recipe, and we know that 1/4 * 2= 1/2 (2/4) we just have to multiply 2 by 2 and get 4, our answer. If the answer is valid please award me the brainiest! It would be much appreciated! :)

Answer:

Step-by-step explanation:

Answer:

(3m - 2) + (2m + 7) + (5m - 3)

Step-by-step explanation:

Perimeter is found by combining all side measurements together to find the total measurement. In this case, combine the sides:

(3m - 2) + (2m + 7) + (5m - 3) is your answer.

If you need a simplified expression, simply combine all the like terms together. Like terms are terms with the same as well as same amount of variables:

(3m + 2m + 5m) + (7 - 2 - 3)

(10m) + (2)

10m + 2 is your answer.

Answer: 275$

Step-by-step explanation:

500

-50 x 8 = -400

500 - (-400) = 100

100 + 175 = 275$

================================================================

Explanation:

The first month has a profit of +500 or simply 500.

The next 8 months have a profit of -50 per month, so we have -50*8 = -400 in profit here. A negative profit indicates debt. So far, the profit is 500 + (-400) = 500 - 400 = 100 dollars. This result is positive, so the company is in good shape so far.

It gets in better shape when adding on the final 175 profit from the tenth month. The final profit is 100+175 = 275 dollars

Answer:

(i) ∠A=∠A (common angle for both triangles)

∠ACB=∠ADE [given]

Therefore, △ABC∼△AED

(ii) from (i) proved that, △ABC∼△AED

So, BC/DE=AB/AE=AC/AD

AD=AB−BD

=6–1=5

Consider, AB/AE=AC/AD

6/3=AC/5

AC=(6×5)/3

AC=30/3

AC=10cm.

Step-by-step explanation:

Step-by-step explanation:

As per given details we can state:

Because:

Therefore:

i) The locus of the points which are equidistant from AB and AC is the line AD as it is the angle bisector of ∠BAC.

The point equidistant from AB and AC is point D

ii) ΔABC is a right triangle, find angle measure of ∠BAC:

Answers:

m = -2/3

b = 1

equation:  y = (-2/3)x + 1

This is the same as writing [tex]y = -\frac{2}{3}x+1[/tex]

===========================================================

Explanation:

There are a few approaches, but I like to start at the y intercept whenever it is an integer. The y intercept is where the diagonal line crosses the vertical y axis. In this case, that location is (0,1) telling us that b = 1 is the y intercept.

From that starting anchor point, we need to find a way to get to another point on this line. There are a few ways to do this, but we can move down 2 and to the right 3 units to go from (0,1) to (3,-1). This "down 2 right 3" motion directly leads to the slope of rise/run = -2/3

---------------

Alternatively, you can start at something like (-3,3) and move down 4 and move right 6 to arrive at (3,-1). Note how rise/run = -4/6 = -2/3. No matter where you start, moving along this line will involve a "down 2 right 3" movement pattern. Be sure to reduce any fractions as much as possible.

Yet another alternative is to apply the slope formula using any two points on the line. Preferably they have integer coordinates.

----------------

However you determine the slope, it's m = -2/3 after fully reducing. It along with b = 1 is plugged into y = mx+b to get y = (-2/3)x+1 as the equation of this line. It's in slope intercept form.

Answer:

  Part A: correct

  Part B: $20

Step-by-step explanation:

The amount Vanessa pays for her printer and 2 cartridges is ...

  $90 +2(25) = $140

The amount Tia pays for her printer and 2 cartridges (c=2) is ...

  t = 80 +20(2) = 120 . . . . dollars

Then the difference in the amounts they pay is ...

  $140 -120 = $20

Answer:

37.5%

Step-by-step explanation:

Ratio = 3 : 5

Total part = 3 +5 = 8

Chocolate donuts = 3/8

[tex]Percentage = \dfrac{3}{8}*100[/tex]

= 37.5 %

Step-by-step explanation:

3 + 5 = 8

we are dealing with 8 parts of the whole.

3/8 + 5/8 = 1

300/8 + 500/8 = 100 = 100%

so,

300/8 is the percentage of the chocolate donuts.

300/8 = 37.5 = 37.5%

Answer:

(- 4, - 10 )

Step-by-step explanation:

y = 5x + 10 → (1)

y = 4x + 6 → (2)

Substitute y = 5x + 10 into (2)

5x + 10 = 4x + 6 ( subtract 4x from both sides )

x + 10 = 6 ( subtract 10 from both sides )

x = - 4

Substitute x = - 4 into either of the 2 equations and evaluate for y

Substituting into (1)

y = 5(- 5) + 10 = - 20 + 10 = - 10

solution is (- 4, - 10 )

Answer: -1

Step-by-step explanation:

Answer:

The correct answers are B and C

Answer:

66 minutes

Step-by-step explanation:

Method I -  proportion

x/44 = 9/6

multiply both sides by 44

x = 9 / 6 * 44

x = 66 minutes

--------------------------

Method II - rate

44/6 = 7.3333333 minutes / mile

9 * 7.3333333 = 66 minutes

Answer:

1/4

Step-by-step explanation:

rise/run = 2/8

take 2/8 and simplify

2/8 divided by 2

you get 1/4

Answer:

Step-by-step explanation:

slope is how much the y value has changed for each unit of x value change.

m = Δy/Δx

It appears that (-4, -2) and (4, 0) are points on the line

m = (0 - (-2)) / (4 - (-4)) = 2/8 = 1/4

as x increases four units, y increases one unit.

45 feet deep

Step-by-step explanation:

First the formula for Parabola is: 4py=x2, we will make it as if it were in the center of the graph.

Now P is the distance from the vertex to the focus or to the directrix which is equal to 20.

4(20)y=x2

80y=x2

Now we just have to use one knwon value of X in the maximum point of the dish, is the diameter of the dish is 120 feet that is the maximum x, and we know that 120 feet is te distance between the widest -x and x, so those would be: -60 and 60.

We will use 60 as our value:

[tex]80y=x^{2} \\80y=60^{2} \\80y=3600\\y=\frac{3600}{80} \\y=45[/tex]

So we know that the depth of the parabolic dish is 45 feet.

In this exercise we have to use the knowledge of depth to be able to calculate the depth that is being seen by the telescope, in this way we can say that:

[tex]45 \ feet \ deep[/tex]

First, knowing that the formula for the parabola is:

[tex]4py=x^2[/tex]

Now P is the distance from the vertex to the focus or to the directrix which is equal to 20, we can say that:

[tex]4(20)y=x^2\\80y=x^2[/tex]

Now we just should use individual knwon financial worth of X fashionable the maximum point of the dish, exist the measurement across object of the eating receptacle exist 120 extremities that is to say the maximum x, and we understand information that 120 extremities is heavy distance middle from two points the expansive -x and x, so those hopeful: -60 and 60.

[tex]80y=x^2\\80y=60^2\\80y=3600\\y=45[/tex]
