Answer:

The image of the given points after the translation is;

(-1,13) , (-2,9) and (-1,-2)

Step-by-step explanation:

By translating vertically to the tune of 5 units, what we have done is to add 5 units to the y-axis value

so for (-1,8); it will become (-1, 8 + 5) = (-1,13)

for (-2,4); it will become (-2,4 + 5) = (-2,9)

for (-1,-7); it will become (-1,-7+ 5) = (-1,-2)

Answer:

The Mean 14.5 and the Median is 15

Step-by-step explanation:

For the Mean you just add all the numbers up and divide on how many you have. And the Median the middle

Answer:

Below in bold.

Step-by-step explanation:

First arrange in ascending order:

5 8 9 11 13 15 16 17 17 18 22 23

Median = mean of the middle 2 values = (15+16)/2 = 15.5.

Mean = Sum of all the values / 12 = 174/12 = 14.5.

Interquartile range =  upper quartile - lower quartile = 17 - 11 = 6.

Answer:

[tex]t=3.142sec[/tex]

Step-by-step explanation:

From the question we are told that:

Speed of ball [tex]V=35m/s\approx 80 mph[/tex]

Length of field [tex]l=110m[/tex]

Generally the equation for Time taken [tex]t[/tex] is mathematically given by

 [tex]t=m/V[/tex]

 [tex]t=110/35[/tex]

 [tex]t=3.142sec[/tex]

 [tex]t \approx \frac{3.142}{60}[/tex]

 [tex]t \approx 0.05hrs[/tex]

Therefore it will take the ball to get from one end of the field to the other

[tex]t=3.142sec[/tex]

Answer:

a = 40π

Step-by-step explanation:

a = (∅/360) * πr²

a = (144/360) * π(10)²

a = 40π

Step-by-step explanation:

Answer:

A) all real numbers greater than or equal to 2

Domain: [tex]x\geq 0[/tex]

Step-by-step explanation:

The variable in the radical x cannot be less than 0 as that wouldn’t be defined. So, the maximum that x can be is 0, and [tex]y=x+2[/tex]. So, 0+2=2, and y is greater than or equal to 2.

Domain is x is greater than or equal to 0 because you cannot square a negative. So, it must not be less than 0. It could be 0 because square root of 0 is just 0.

Answer:

one board game cost 15 dollars

75/5=15

15y

y = number of board games and 15= the price of each board game

so to calculate any number of board games bought just input the number of board games bought for y in the expression 15y and you will get the price.

Step-by-step explanation:

Answer:

79 minutes

Step-by-step explanation:

A plane is travelling at 180 meters per seconds

Convert to km/hr

180× 18/5

= 648 km/hr

Since 648 km equals 1 hour then the number of minutes required for the plane to travel 800 km is

= 1/648 × 800

= 1 hour 19 minutes

Conver the time to full minutes

60 minutes = 1 hour

= 60+19

= 79 minutes

Hence the minutes required for the plane to travel 800km is 79 minutes

Answer:

(-3, -2)

Step-by-step explanation:

To find the solution of two functions, you need to know at which x and y value they are equal. So solve for x and y when 1/3x - 1 = 2x + 4

1/3x - 1 = 2x + 4

First, subtract 2x from both sides.

-5/3x - 1 = 4

Add one to both sides.

-5/3x = 5

Multiply both sides by the reciprocal of -5/3 (3/-5)

x = -3

Then, substitute x into one of the equations to get y.

1/3(-3) - 1

-1 - 1 = -2

So drag the dot to the point (-3, -2)

Answer:

3rd option is correct

Step-by-step explanation:

:)

The vertex form of the equation is [tex]f(x) = (x+1/2)^2 + 3/4[/tex]

Given the expression [tex]f(x) = x^2 + x +1[/tex]

The vertex form is expressed as shown below:

[tex]f(x) = x^2 + x +1\\f(x) = x^2 + x + 1^2 +1 - 1^2\\f(x) = (x+1)^2 - 0[/tex]

Express the result in vertex form.

[tex]f(x) = (x+1/2)^2 + 3/4[/tex]

Hence the vertex form of the equation is [tex]f(x) = (x+1/2)^2 + 3/4[/tex]

Answer: B, E

Step-by-step explanation:

Answer:

TQ=SR [since it is isosceles trapezoid]

6x+1.2=9x-48

48+1.2=9x-6x

3x=49.2

x=49.2/3=16.4

now

QR=3×16.4+2.5=51.7

SR=9×16.4-48=99.6

ST=4×16.4-2=63.6

TQ=6×16.4+1.2=99.6

As it's isosceles trapezoid

Now

QR=3(2)+2.5=8.5

RS=9(2)-4.8=13.2

ST=4(2)-2=6

QT=6(2)-1.2=10.8

Answer: Reflection about x-axis

Step-by-step explanation:

Given

Initially, vertices are [tex]A(-2,0), B(2,5),C(3,1)[/tex]

After reflection they become [tex]A(-2,0),B(2,-5),C(3,-1)[/tex]

It is clear that the x coordinate remains unchanged and the y coordinate changes its sign. It occurs when reflection is done about the x-axis.

For example, when (a,b) is reflected about the x-axis, it becomes (a,-b).

So, here reflection is being done about the x-axis.

Step-by-step explanation:

Boys to girls is 2:3

and there are 18 boys so that means the 2 in 2:3 is actually 18

and 2 x 9 = 18 , so you would need to also multiply 3 by 9.

3 x 9 = 27

18:27
