Step-by-step explanation:

(fg)(x) )

[tex](x+4)*(3x^{2} -7)[/tex]=[tex]3x^{3} -7x+12x^{2} -28[/tex] = [tex]3x^{3} +12x^{2} -7x-28[/tex]

Composite functions are functions that are gotten from combining multiple functions.

The value of the composite function (f o g)(x) is 3x^2 -3.

The functions are given as:

[tex]f(x) = x + 4[/tex]

[tex]g(x) = 3x^2 - 7[/tex]

To calculate the composite function (f o g)(x), we make use of:

[tex](f\ o\ g)(x) = f(g(x))[/tex]

We have:

[tex]f(x) = x + 4[/tex]

Substitute g(x) for x

[tex]f(g(x)) = g(x) + 4[/tex]

Substitute [tex]g(x) = 3x^2 - 7[/tex]

[tex]f(g(x)) = 3x^2 - 7 + 4[/tex]

[tex]f(g(x)) = 3x^2 -3[/tex]

Recall that:

[tex](f\ o\ g)(x) = f(g(x))[/tex]

So, we have:

[tex](f\ o\ g)(x) = 3x^2 -3[/tex]

Hence, the value of the composite function (f o g)(x) is 3x^2 -3.

Answer:

the answer is B that is

ΔABC is similar to ΔEDC

Step-by-step explanation:

look at the figure abc and edc completely match together as a is a right angle and is at the the first, similarly e is also a right angle and is at the first. also b is at the same place as d i.e. in between the right angle and the last angle.

moreover, c is at the last in abc just like in edc

Answer:

∠ CAD = 83°

Step-by-step explanation:

In a parallelogram. opposite angles are congruent.

∠ CAB = ∠ ACD = 57° ( Alternate angles )

The sum of the 4 interior angles = 360°

and

∠ ABC + ∠ CDA = 40° + 40° = 80°

Thus

∠ BCD + ∠ CAD = 360° - 80° = 280°, then

∠ DAB = 140° ( congruent opposite angles )

Thus

∠ CAD = 140° - ∠ CAB = 140° - 57° = 83°

Answer:

One: x =  3/32

Two: y =  3/10

Step-by-step explanation:

One

y = k*x

1/4 = k* 1/8                    Multiply both sides by 8

8(1/4) = 8*k*(1/8)

8/4 = k

k = 2

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

3/16 = 2*x                      Divide by 2

3/32 = x

Two

y = 2/5

x = 1/3

2/5 = k * 1/3                   Multiply both sides by 5

2 = 5*k * 1/3

2 = 5/3 * k                     Multiply both sides by 3

6 = 5 * k                        Divide both sides by 5

6/5 = k

y = 6/5 * x

x = 1/4

y = 6/5 * 1/4

y = 6/20 = 3/10

Answer:   If a team uses 75 water bottles when the temperature is 60 degrees, ( 75 - 15 = 60 )

I guess if they have 120 bottles, you'd have to take away 15 again, which = 105

Answer:

1. 9.8 cm

2. 44.5 cm^2

Step-by-step explanation:

1. To find the length of arc AB, we use the formula for the length of an arc

Mathematically, that will be;

theta/360 * 2 * pi * r

theta is the central angle which is 51

r is the radius which is 10 cm

So we have

51/360 * 2 * 22/7 * 10 = 8.9 cm

2. The area of the sector

we use the formula for the area of a sector here,

That is;

theta/360 * pi * r^2

51/360 * 22/7 * 10 * 10

= 44.5 cm^2

Answer:

1/10

Step-by-step explanation:

A number line is a line which contains numbers marked at intervals (usually regular intervals). Points to the right of the origin are positive numbers while those to the left are negative numbers.

The school is used as the origin. Ellie house is 1 and three fifths blocks east (to the right) of the school. This means that it is + 1 and three fifths (+8/5).

Chase house is 1 and one half blocks (3/2) west of Ellie. Since it is west then it is to the left. Hence the coordinate of chase house = 8/5 - 3/2 = 1/10

Hence the coordinate of chase house is 1/10(one tenths).

The error may be as a result of thinking chase house is to the east of Ellie, hence adding to get  3 and one tenth.

Answer:

Inverse Function: f^-1(x) = 9/4x + 9

Step-by-step explanation:

To find  the inverse function we can interchange the position of the variables x and y, and then solve for y;

y = 4/9x - 4 => x = 4/9y - 4,

x = 4/9y - 4,

4/9y = x + 4,

y = 9/4x + 9/4(4),

y = 9/4x + 9/ f^-1(x) = 9/4x + 9

Answer:

2b( 12 - 17a)

Step-by-step explanation:

This is the answer because:

1) Fator 2b out of 24b - 34ab:

2b x 12 = 24b = 24b ÷ 2b = 12

2b x 17a = 34ab = 34ab ÷ 2b = 17a

Therefore, the answer is 2b( 12 - 17a).

Answer:

area of circle = 2464 cm²

Step-by-step explanation:

circumference = 176 cm

formula of circumference = 2πr

2πr = 176 cm

2 × 22/7 × r = 176 cm

44/7 ×r = 176 cm

r = 176 ÷ (44/7)

r = 176 × 7/44

r = 28 cm

area of circle

= πr²

= 22/7 × 28²

= 22/7 × 784

= 2464 cm²

Step-by-step explanation:

An = A + (n - 1)d

We have An = 81, d = -3 and n = 18.

Hence A = An - (n - 1)d = 81 - (17)(-3) = 132.

Answer:

ratio number 1-  14:12

ratio number 2- 21:18

ratio number 3- 28:24

Answer: 31.18

Step-by-step explanation:

The problem is focused on mainly the right triangle made up of points M, Q, and R.  This problem can be solved with the base formula, b = a · tan(β) where a = the length of line MR, β = m∠MQR, and b is the unknown length of RQ.  

Given:

RQ = 18 · tan(60°)

Point M is the midpoint of line PM and line MR.  Since MP is equal to 18, MR has to be 18 as well.  This means that the value of a is 18.

The vertex of ∠MQR is Q, which is 60°.

Step 1: Find the tangent of 60°

The tangent of 60° is √3

Step 2: Solve

RQ = 18 · √3

18 · √3 = 31.18

RQ is equal to 31.18
