Answer:

f(4) = 6

Step-by-step explanation:

Given the rule f(n) = 4f (n - 1) + 2 where f(1) = 3, f(n) is just a fancy way to name the variable y. As you've seen before, there are equations that are usually y equals x and something. For example:

y = mx + b

is the same thing as

f(n) = y = mn + b.

It might be that you have multiple of the same equation where f(n) and f(x) have two different outcomes.

The f(n) part (bolded) is the "x variable" in this equation. So in f(1), n = 1.

f(n) = 4f (n - 1) + 2

f(n) = (4fn - 4f) + 2

f(n) = (n) + 2

f(1) = 1 +2

3 = 3

Now do the same thing for f(4):

f(n) = 4f (n - 1) + 2

f(n) = (4fn - 4f) + 2

f(n) = (n) + 2

f(4) = 4 + 2

f(4) = 6

Answer:

9/5 or 1.8

Step-by-step explanation:

triangle aed is larger than triangle abc by a scale factor of 5; we know this because side ed is 5 units and cb, the corresponding side in triangle abc, is 1. if ad has a length of 9, the length of ab must be 9 divided by five. thus, z is equal to 9/5 or 1.8.

Answer:

6 hours

Step-by-step explanation:

For Bob

12 hours = 1 fence

1 hour = 1/12 fence

Together Bob and Jen

4 hours = 1 fence

1 hour = 1/4 fence

Now, for Jen:

1 hour = 1/4 - 1/12= 3/12 - 1/12 = 2/12=1/6

Find the amount of time Jen will need:

1/6 fence = 1 hour

1 fence = 6 hour

Answer:

[tex](a)\ b = 8[/tex]

[tex](b)\ T = 3.1[/tex]

Step-by-step explanation:

Given

[tex]y = 2\sqrt x[/tex]

See attachment

Solving (a): Find b

At point b, [tex]x = 16[/tex]

So, the value of b is:

[tex]b = 2 * \sqrt{16[/tex]

[tex]b = 2 * 4[/tex]

[tex]b = 8[/tex]

Solving (b): Find T

First, we calculate the value of y at point T

[tex]y = 2\sqrt x[/tex]

At point T, [tex]x = 6[/tex]

So:

[tex]y = 2 * \sqrt 6[/tex]

[tex]y = 2 * 2.45[/tex]

[tex]y = 4.9[/tex]

To calculate T, we subtract the calculated height (y) from the value of b

[tex]T =b - y[/tex]

[tex]T = 8 - 4.9[/tex]

[tex]T = 3.1[/tex]

Answer:

A) 64.5

Step-by-step explanation:

A circle's measurement is 360°.

It is given that arcPQ is 113° and arcQM is 118°. Subtract 113 and 118 from 360:

360 - (113 + 118) = 129°

ArcPM is 129 degrees. Note that this is a inscribed, but not a central angle. m∠PQM = (ArcPM)/2

m∠PQM = (129)/2

m∠PQM = 64.5

A) 64.5 is your answer.

Answer: The correct answer would be F. Half the students drank from 78 to 114 fluid ounces.

Step-by-step explanation:

The statement best describes the data represented in the box plot half the students drank from 78 to 114 fluid ounces. The correct option is F.

A rectangle is created to represent the second and third quartiles, normally with a vertical line inside to indicate the median value, in a simple way of presenting statistical data on a plot.

Given that students recorded the amount of liquid in fluid Ounces each of them drank In one day. The box plot shows the summary of the results. Amount of Liquid (fluid Ounces).

The highest and the lowest limit of the box plot is range from 78 to 114. The statement best describes the data represented in the box plot half the students drank from 78 to 114 fluid ounces.

Therefore, the correct option for the box plot will be F.

Step-by-step explanation:

(x - y)² = x² - 2xy + y²

x = x and y = a

2xy = 8x

2*x*a = 8x

     a = [tex]\frac{8x}{2x}[/tex]

a = 4

Answer:

The value of 6(2b-4) is 36.

Step-by-step explanation:

Given expression: 6(2b-4)

To find the value of 6(2b-4) at b=5, we need to substitute the b=5 in the expression, we get

6(2(5)-4)

= 6(10-4)

=6(6)

= 6x6=36

⇒ 6(2(5)-4)=36

Answer:

The value of 6(2b-4) when b=5 is 36.

Step-by-step explanation:

Given expression: 6(2b-4). To find the value of 6(2b-4) at b= 5, we need to substitute the b=5 in the expression, we get….Therefore, the value of 6(2b-4) is 36, when b=5.

Answer:

y - 20 = (-1/5)(x - 5)

Step-by-step explanation:

The slope of the given line is 5.  The slope of any line perpendicular to the given line is the negative reciprocal of the given slope:  

Slope of perpendicular line here is -1/5.

We use the point-slope formula as a framework here:

y - 20 = (-1/5)(x - 5)

The answer is (1,-5), If you put those two on a graph, that point is where they collide.
