Answer:

[tex]h(f(x)) =6x-2[/tex]

Step-by-step explanation:

Given

[tex]f(x) = (3x-5)^3\\h(x) = 2\sqrt[3]{x}+8[/tex]

Required

Write [tex]h(f(x))[/tex] in terms of x

[tex]h(f(x)) = h((3x-5)^3)[/tex]

To get [tex]h((3x-5)^3)[/tex], we will replace x in h(x) with (3x-5)³ as shown:

[tex]h((3x-5)^3) = 2\sqrt[3]{(3x-5)^3} +8\\ h((3x-5)^3) = 2(3x-5) + 8\\ h((3x-5)^3) = 6x - 10 + 8\\ h((3x-5)^3) = 6x-2\\Hence \ h(f(x)) =6x-2[/tex]

Hence the expression [tex]h(f(x))[/tex] in terms of x is 6x - 2

Answer:

Sorry, but i don't see any graph.

Step-by-step explanation:

We have a lot of square roots, and we want to find, for each one, two consecutive integers such that one is smaller than the square root and the other is larger.

The solutions are:

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

To find the integers, we just need to find two integers such that one squared is smaller than the argument of the square root and the other squared is larger than the argument of the square root.

1) √120

Here we can use:

10*10 = 100

11*11 = 121

Then:

10 < √120 < 11

2) √56

Here we can use:

7*7 = 49

8*8 = 64

then:

7 < √56 <  8

3) √19

Here we can use:

4*4 = 16

5*5 = 25

then:

4 < √19 < 5

4) √240

Here we can use:

15*15 = 225

16*16 = 256

then:

15 < √240 < 16

5) √80

Here we can use:

8*8 = 64

9*9 = 81

then:

8 < √80 < 9

6) √27

Here we can use:

5*5 = 25

6*6 = 36

then:

5 < √27 < 6

7) √199

Here we can use:

14*14 = 196

15*15 = 225

then:

14 < √199 < 15

8) √38

Here we can use:

6*6  = 36

7*7 = 49

then:

6 < √38 < 7

9) √102

Here we can use:

10*10 = 100

11*11 = 121

then:

10 < √102 < 11

10) √11

Here we can use:

3*3 = 9

4*4 = 16

then:

3 < √11 < 4.

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

Let's look at each option:

A. Distance =600 ✓

This is because the graph is a distance- time graph. To find the distance between her house and the post office, look at the y value of the point at the end of her journey. In this case, at t=24 mins, the y -value is 600 and thus the statement is correct.

B. ✓ correct

First 9 mins is from t=0 to t=9. Speed can be found by taking the gradient of the line of a distance- time graph.

Gradient can be found by taking rise/ run, which is also the difference in the y- coordinates divided by the difference in the x -coordinates.

[tex]\boxed{ gradient = \frac{y1 - y2}{x1 - x2} }[/tex]

[tex]gradient \\ = \frac{315}{9} \\ = 35[/tex]

Thus, the speed in the first 9 minutes is indeed 35m/min.

C. ✓correct

Since distance remained at 315m from t=9 to t=13mins, she stopped for that period of time.

Time stopped

= 13 -9

= 4 minutes

D. Incorrect

Average speed= total distance/ total time

Total distance= 600m

Total time= 24 mins

Thus, average speed

= 600 ÷24

= 25m/min

Mean is 5.2, median is 5 and S.D is 2.135

Given data 2, 4, 5, 7, 8

We need to find mean, Median and standard deviation

Mean = Sum of Observations/ Number of observations

Median=Middle most Number when arranged in a sequence

Mean = (2+4+5+7+8)/5=26/5=5.2

Median= 5

Standard deviation:

S.D=∑(x- bar)^2/N

To find sD

Subtract mean from each value

2-5.2=-3.2

4-5.2=-1.2

5-5.2=-0.2

7-5.2=1.8

8-5.2=2.8

Square each of those differences

-1.2*-1.2=1.44

-3.2*-3.2=10.24

-0.2*-0.2=0.04

1.8*1.8=3.24

2.8*2.8=7.84

Determine the average of those squared numbers to get the variance.

1.44 + 10.24 + 0.04 + 3.24 + 7.84 = 22.8

Average = 22.8/5=4.56

To find the standard deviation make square root of variance

2.135

Therefore Mean is 5.2, median is 5 and S.D is 2.135

So the formula is [tex]y^2-y^1= rise\\x^2-x^1= run[/tex]

All you have to do is the second y-coordinate of the points minus the first y-coordinate. That should be -6 - 3= -9

Answer:

From 0 to 31.43 minutes Plan 2 is cheaper. From 31.44 Plan 1 is better.

Step-by-step explanation:

First, we need to structure the total cost formula for each fitness center:

Plan 1= 22.99

Plan 2= 11.99 + 0.35x

x= number of minutes

Now, we equal the formulas and isolate x:

22.99= 11.99 + 0.35x

11=0.35x

31.43=x

The indifference point is 31.43 minutes.

From 0 to 31.43 minutes Plan 2 is cheaper. From 31.44 Plan 1 is better.

Step-by-step explanation:

Slope = ( y2-y1) / (x2-x1)

= (1- (-5)) / (4-1)

= (1+5) / 3

= 6/3

= 2

The slope of the line that goes through the points (1.-5) and (4.1) will be 2. Option D is correct.

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. A straight line is a combination of endless points joined on both sides of the point. A linear equation has the form y = mx + b in the slope-intercept format. X and Y are the variables in the equation. The values m and b represent the line's slope (m) and the value of y when x is 0. The slope 'm' of any straight line is given by:

m =(y₂-y₁)/(x₋-x₁)

It is given that, the line that goes through the points (1.-5) and (4.1).

(x₁,y₁) = (1.-5)

(x₂,y₂)= (4.1)

m =(y₂-y₁)/(x₋-x₁)

m= (1- (-5)) / (4-1)

m= (1+5) / 3

m= 6/3

m= 2

Thus, the slope of the line that goes through the points (1.-5) and (4.1) will be 2. Option D is correct.
