Step-by-step explanation: you plug in -1 as x for g(x) and you use the answer from that (which is 6) and plug that into f(x)

The value of composite function (fog)(-1) = 10/3.

A function whose values are obtained from two given functions by first applying one to an independent variable and then using the result to apply the second, and whose domain is made up of those independent variable values for which the first function's result falls within the second function's domain.

The two functions are given below:

f(x) = 8/x+2

g(x) = 4x² + 2

To evaluate the composite value  (fog)(-1), first solve for g(-1).

Put x = -1 in 'g' function

g(x) = 4x² + 2

g(x) = 4(-1)² + 2

      = 4 + 2

g(x)  = 6

Now, substitute the value of g(6) in 'f' function

f(x) = 8/x+2

f(6) = 8/6 + 2

     = 10/6

Therefore, the composite value (fog)(-1) = 10/3.

Answer:

1. 14 = 2 + 12

2. 16 = 4 + 12

3. 18 = 6 + 12

4. 20 = 8 + 12

Step-by-step explanation:

Super easy. All you do is replace the numbers in your table with the corresponding letter. In this case we have a table of s and f.

Example for row two: f = s + 12. Replace s with 4 ( 4 is from your s column so you would replace it with that) then solve and plug in your answer (When you solve your answer, it will go under f column).16 = 4 + 12 . f = 16, s = 4.

Formula = f = s + 12.

1. 14 = 2 + 12

2. 16 = 4 + 12

3. 18 = 6 + 12

Answer:

84

Step-by-step explanation:

180-51-45=84

I think this would be the answer since triangles add up to be 84 and we are just finding the last missing angle.

hope this helps :)

Answer:

the answer is c - 84

Step-by-step explanation:

every triangle adds up to 180, so if you subtract 51 and 45 from 180, you will get 84

Answer:

To find the distance between any two points, you can use the distance formula. However, the two ordered pairs have the same "x-coordinate" so all we really have to find is the distance of the y coordinates.

To get from 3 to -6, we have to move 3+6, or 9 units.

So, the answer would be 9 units.

3x³ + 12x² - 7x - 28

Step-by-step explanation:

(f • g)(x) = f(x) × g(x)

= (x + 4)(3x² - 7)

Each term in the second factor is multiplied by each term in the first factor, that is

x(3x² - 7) + 4(3x² - 7 ) ← distribute both parenthesis

= 3x³ - 7x + 12x² - 28

= 3x³ + 12x² - 7x - 28

Answer:

they both use y^2-y^1 and x^2 - x^1, one is to find the slope the other is to find the y intercept

Step-by-step explanation:

Slope-intercept is when you have a graph and a equation such as y=mx+b

y = y coordinate

m = slope

x = x coordinate

b = y intercept

point-Slope is when you have this equation and you use (x1, y1) as the coordinates to graph.

y - y1 = m * (x - x1)

Answer:

The answer is SPHERE

Step-by-step explanation:

i took the flvs test and got it correct

There is a circular cross-section with a center at (1, 1) and radius of 1 is rotated about the line y = 1 so it should be a sphere.

It is the geometrical object that contains the three-dimensional where it analog the two-dimensional circle.

It is the set of the point that have the similar distance with respect to the three-dimensional space

Hence, the third option is correct.

Answer:

Adult ticket is $15

Child ticket is $5

Step-by-step explanation:

Let x = adult ticket price

     y = child ticket price

2x + 3y = 45          2x + 2y = 40

-2x - 2y = -40

          y = 5            2x + 2(5) = 40

                                 2x + 10 = 40

                                 2x = 30

                                   x = 15

The prices of the adult movie tickets and the child movie tickets are $15 and $5 respectively.

Given that, the Jones family spent $45 on movie tickets for 2 adults and 3 children.

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

Let cost of adult tickets be x and the cost of children tickets be c.

The Jones family spent $45 on movie tickets for 2 adults and 3 children.

2a+3c=45 ------(I)

The Smith family spent $40 for 2 adults and 2 children.

2a+2c=40

a+c=20 ------(II)

From equation (II), we have a=20-c

Substitute a=20-c in equation (I), we get

2(20-c)+3c=45

⇒ 40-2c+3c=45

⇒ c=$5

Put c=5 in equation (II), we get

a+5=20

⇒ a=$15

Therefore, the prices of the adult movie tickets and the child movie tickets are $15 and $5 respectively.

D. [tex]a = 0.01025[/tex], [tex]b = 1[/tex]

Step-by-step explanation:

Mathematically speaking, an exponential function is a trascendental function of the form:

[tex]y = a^{b\cdot x}[/tex] (1)

Where:

[tex]a[/tex] - Initial amount.

[tex]b[/tex] - Growth factor.

[tex]x[/tex] - Independent variable.

[tex]y[/tex] - Dependent variable.

Let [tex]y = 0.01025^{x}[/tex], by direct comparison we find that values for initial amount and growth factor are, respectively:

[tex]a = 0.01025[/tex], [tex]b = 1[/tex]

Answer:

73.3 km/h

Step-by-step explanation:

Average rate of speed = total distance/total time

First distance is 160

Second distance = rt = 85(2) = 170

total distance = 160 + 170 = 330

total time = 2.5 + 2 = 4.5

Average speed = 330/4.5 = 73.3 km/h
