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.

move the decimal place 4 places to the Left because it is a negative.  

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

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.

sin 60 = h/12

h = 12sin60

h = 12* √3/2 = 6√3 cm

Answer: 1) 4:1  2) 60/48

Step-by-step explanation:

1.  12: 3 is the same as 12/3 so you can diving both side by 3.

12:3 ÷ 3/3=4/1

2. 30:24 is the same as 30/24 so you can divide both sides by 6 or multiply both sides by 2.

30/24 * 2/2= 60/48

Answer:

755 m²; 785 m²

Step-by-step explanation:

In the picture attached, the prism is shown.

Lateral area = perimeter of base * height

The base is a right triangles, then its perimeter is:

perimeter: 5 + 6 + 11.21 = 22.21 m

Lateral area = 22.21*34 = 755 m²

Surface area = lateral area + 2 (Area of base)

The base is a right triangles, then its area is:

area of base = (1/2)*5*6 = 15 m²

Surface area = 755 + 2*15 = 785 m²

Answer: All of them do

Explanation: I would check with your instructor on this one.

The mode is the number that appears most frequently in a data set.

In all these sets here, there is a number that appears most frequently.

However, there are two sets that have 2 modes.

These sets are 5, 1, 3, 1, 5 and -2, -2, -2, 2, 2, 2.

Answer:

Number of candy left = 5

Step-by-step explanation:

Given:

Number of bags = 4

Number of candies in each bag = 8

Number of Gift boxes = 9

Find:

Number of candy left = ?

Computation:

Total number of candies = Number of bags × Number of candies in each bag

Total number of candies = 4 × 8

Total number of candies =  32

According to Euclid division lemma:

a = bq +r

32 = (3)(9) + Remainder

32 = 27 + Remainder

Remainder = 5

Number of candy left = 5

Answer:

slope = [tex]\frac{5}{3}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

5x - 3y - 12 = 0 ( subtract 5x - 12 from both sides )

- 3y = - 5x + 12 ( divide all terms by - 3 )

y = [tex]\frac{5}{3}[/tex] x - 4 ← in slope- intercept form

with slope m = [tex]\frac{5}{3}[/tex]

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.
