The graph shows the number of students who earned a score in math. Find the domain.

A) 10 < x < 100
B) {0, 5, 10, 15, 20, 25}
C) 0 ≤ x ≤ 24
D) {10, 20, 30, 40, 50, 60, 70, 80, 90, 100}

Answer:

The correct option is the letter "C", [tex](x + 2)^2 + (y + 10)^2 = 1.44[/tex].

Step-by-step explanation:

The standard form for a circle's equation has the following structure:

[tex](x - x_c)^2 + (y - y_c)^2 = r^2[/tex]

Where [tex](x_c,y_c)[/tex] are the coordinates of the center of the circle and [tex]r[/tex] is the radius. Applying the data from the problem we have:

[tex](x - x_c)^2 + (y - y_c)^2 = r^2\\\[[x - (-2)]^2+ [y - (-10)]^2 = (1.2)^2\\(x + 2)^2 + (y + 10)^2 = 1.44[/tex]

Therefore the correct answer is the letter "C", [tex](x + 2)^2 + (y + 10)^2 = 1.44[/tex].

Answer:

1. 17/12

2. 12/17

Step-by-step explanation:

The teacher is 1.42 times as tall as the student and the required fraction is given by 17/12

The quantitative relation between two amounts shows the number of times one value contains or is contained within the other. for example-"the ratio of computers to students is now 2 to 1"

Given here; Height of the student = 4 ft. and height of teacher =5²/₃

Ratio of the height of the teacher and student is

= 5+2/3  / 4   ( 5²/₃=5+2/3 , property of mixed fractions)

= 17/3 × 1/4

=17/12

=1.4166

Thus we can say that the height of teacher is 1.42 times as tall as the student.

Also as given above the teacher's height is 17/12 the students height.

Hence, The teacher is 1.42 times as tall as the student and the required fraction is given by 17/12

Answer:

8.75 in.

Step-by-step explanation:

See attachment for the figure.

As you can see, ∆ HBA & ∆HKJ are similar,

HB/HA = HK/HJ  

3/5.25 = 8/HJ

3HJ/5.25 = 8

3HJ = 42

HJ = 14 in.

AJ = 14 - 5.25

AJ = 8.75 in.

Therefore,  the length of Line segment AJ is 8.75 in.

Answer:

(B) 8.75

Step-by-step explanation:

Answer:

see below

Step-by-step explanation:

Is means equal and of means multiply

36 = 75% * 48

36 = .75* 48

36 = 3/4* 48

36 =36

Using the tape diagram

Divide 48 into 4 pieces

12    12     12    12

Then circle 3 of them

36

Answer:

Correct

Step-by-step explanation:

75% of 48

75/100 × 48

3/4 × 48

36

Divide the tape of length 48 units into 4 parts, 3 parts add up to 36

Answer:

5(x-4)-6

Step-by-step explanation:

If we subtract 6 from both sides, using the additive property of equality, we get that y, or f(x), equals 5(x-4)-6

Answer:

y=-4x+11

Step-by-step explanation:

We can use the point-slope form of a line to solve this, which is

y - y₁ = m (x - x₁), where (x₁ , y₁) is a point and m is the slope.

We have:

y - 3 = -4(x - 2)

y - 3 = -4x + 8

y = -4x + 11

Answer:

x = - 5, x = - 11

Step-by-step explanation:

Given

y = [tex]\frac{x+4}{(x+5)(x+11)}[/tex]

The denominator cannot be zero as this would make y undefined.

Equating the denominator to zero and solving gives the values that x cannot be, that is

(x + 5)(x + 11) = 0

Equate each factor to zero and solve for x

x + 5 = 0 ⇒ x = - 5

x + 11 = 0 ⇒ x = - 11

Thus

x = - 11 and x = - 5 are excluded values.

Step-by-step explanation:

the x (6) is the horixontal ways on the co-ordinate plane. you go right until you reach the six. the y (4) is vertical. take the point that is on 6,0. and move it up until you see it on 4. now you have the coordinates 6,4.

Answer:

195

Step-by-step explanation:

To find the 23rd term of this sequence, we can use the arithmetic sequence formula [tex]a_{n} =a_{1} +(n-1)d[/tex] where,

[tex]a_{n}[/tex] = [tex]n^{th}[/tex] term

[tex]a_{1}[/tex] = first term

[tex]n[/tex] = term position

[tex]d[/tex] = common difference

[tex]a_{23}=-25+(23-1)10[/tex]

[tex]a_{23} =195[/tex]

Answer:

95.36 ft

Step-by-step explanation:

Volume of a Cone[tex]=\frac{1}{3}\pi r^2 h[/tex]

Radius=7 ft, Height=12 ft

Therefore the volume of sand in the cone

[tex]=\frac{1}{3}\pi *7^2*12\\=615.7522$ ft^2[/tex]

If the sand was used to build as pyramid with a base of 4ft by 5ft.

Volume of a Pyramid[tex]=\frac{1}{3}*$Base Area* Height[/tex]

[tex]615.7522=\frac{1}{3}*(4*5)* Height\\615.7522=\dfrac{20}{3}* Height\\$Multiply both sides by \dfrac{3}{20}\\$Height =615.7522*\dfrac{3}{20}\\\\$Height of the pyramid=95.36 ft[/tex]

Answer:(15, 100)

Step-by-step explanation:

first find the coordinates of the point above (3, 20)

you just look at the x axis and where the point is in this case x would be 6 and then you find y which would be 40

so the coordinate would be (6, 40)

now subtract (6, 40) by (3, 20)

6-3= 3

40- 20= 20

you get the first coordnites which is what you add (12,80) to

12 +3= 15

80+ 20= 100

you get the coordinates (15, 100)

Answer:

she was a woman.

Answer:

Yes

Step-by-step explanation:

A function has one input (x-value) per output (y-value).

In other words, a relation that does not repeat any x values is a function.

{(3,4) , (5,0) , (2,4) , (-5,-5)}

The domain of the relation is:

{-5,2,3,5}

Since none of the numbers repeat in the domain, the relation is a function.
