Answer:

$49

Step-by-step explanation:

Cost of security system installation = $50

Let the monthly service cost be $x

tax percentage = 6% of monthly service  cost

hence if monthly service cost is $x

Then Tax value in terms of x is =   6% of  $x  = 6/100 * $x =$ 0.06x

_______________________________________________

Therefore total cost incurred by Trevor in 6 month including installation charges =

6 month monthly service cost + Tax value in 6 month + installation cost

Substituting value of 6 month monthly service cost , Tax value in 6 month , installation cost in above expression we have

Therefore total cost incurred by Trevor in 6 month including installation charges = $6x+  $0.36x+ $50 = $6.36x + $50

But it is given that After 6 months, Trevor had paid a total of $361.64 for his service fee, taxes, and his initial installation

Therefore total cost incurred by Trevor in 6 month including installation charges  is also equal to $361.64

Hence,

$6.36x + $50 = $361.64

=> $6.36x = $361.64 - $50

=>$6.36x = $311.64

=> x = $311.64/6.36

=> x = 49.

Therefore , Trevor’s monthly service fee, not including taxes is $X which is equal to $49.

Answer:

[tex]\sqrt{24}[/tex]

Step-by-step explanation:

[tex]4\frac{4}{9}[/tex] cannot be correct because it equals 4.4.

[tex]\sqrt{20}[/tex] cannot be correct because it equals 4.5.

480% is 480/100 which equals 4.8 which is also not correct.

Therefore, [tex]\sqrt{24\\}[/tex] is correct because it is greater than 4.8 and less than 5.0.

Answer:

Side AB is 10 cm.

Step-by-step explanation:

The given quadrilaterals ABCD and EFGH are similar.

From the given figure, we can observe the following angles and sides are corresponding.

[tex]\angle A = \angle E=90^\circ\\\angle B = \angle F=63^\circ\\\angle C = \angle G=117^\circ\\\angle D = \angle H=90^\circ[/tex]

Ratio of corresponding sides will be equal:

AB:EF = BC: FG = CD:GH = DA:HE

We have to find the side AB.

Given the sides

EF = 5 cm

BC = 9 cm

DA = 8 cm

EH = 4 cm

So, ratio DA:EH = 8:4 = 2:1

We know that ratio of corresponding sides will be same:

AB:EF = DA:EH

[tex]\Rightarrow \dfrac{AB}{5} = \dfrac{2}{1}\\\Rightarrow AB = 10 cm[/tex]

So, side AB is 10 cm.

The correct option is D. The graph z is representing a quadratic function.

In algebra, a polynomial function with one or more variables in which the highest-degree term is of the second degree is known as a quadratic function, a quadratic polynomial, a polynomial of degree 2, or simply a quadratic.

The general form of the quadratic functions is represented as below:-

y = ax² + bx + c

Where a,b, and c are the constants x and y are variables.

The graph of the quadratic functions will be parabolic on the x-y plane.

Therefore, the correct option is D. The graph z is representing a quadratic function.

Step-by-step explanation:

a-4ft 8in

b-4ft

c-3ft 4in

d-3ft

Answer:

it's A, one yard and 20 inches

Step-by-step explanation:

If you convert them all to inches,  a yard and a 20 inches are equal to 56 inches, so you can rule out the 40 inches answer. a yard and a foot are equal to 48 inches, so we can rule out that also. 3 feet is equal to 36 inches, because we know that a foot is equal to 12 inches. so you are left with A. 1 yard and 20 inches.

Step-by-step explanation:

Answer:

It's D.

Step-by-step explanation:

The 1/2 stretches the graph horizontally of x^2 by a factor 1/2.

Option-D will represent the required graph of the function [tex]g(x) = \frac{1}{2}f(x)[/tex].

"A function is defined as a relation between a set of inputs having one output each."

The given function:

[tex]f(x) = x^{2}[/tex]

Therefore the required function is:

[tex]g(x)\\= \frac{1}{2}f(x)\\= \frac{1}{2}x^{2}[/tex]

By putting the values of 'x' as -2, -1, 0, 1, 2 etc. we get:

[tex]g(-2) = (-2)^{2} = 4\\ g(-1) = (-1)^{2} = 1\\ g(0) = (0)^{2} = 0\\ g(1) = (1)^{2} = 1\\ g(2) = (2)^{2} = 4[/tex]

By plotting this value, we get option-D is the graph that represents the function g(x).

Answer:

g^−1(7) = 6

h^−1(x) = x/2 + 3/2

(h^−1 ∘ h)(3) = 3

Step-by-step explanation:

If

g(6) = 7

Then

g^−1(7) = 6

h(x) = 2x - 3

Isolate x:

2x = h(x) + 3

x = h(x)/2 + 3/2

Replace x with h^−1(x) and h(x) with x:

h^−1(x) = x/2 + 3/2

We know that:

(h^−1 ∘ h)(x) = x

then:

(h^−1 ∘ h)(3) = 3
