7) H
8) C
Step-by-step explanation:
7)
Dilation is a transformation we apply that increases the dimensions of something proportionally, that is, each dimension is multiplied by the same constant value.
Therefore, the correct option is H, where the x and y coordinates are multiplied by the same value (3).
8)
We can see in steps 1 and 2 that he draws the heights relatives to the sides AB and BC. The crossing point of heights in a triangle is known as the orthocenter (point D). the third figure shows that the triangle is inscribed in a circumference (all the vertex of the triangle are on the circumference). If the triangle is inscribed within the circumference, the circumference is circumscribed about the triangle.
So the correct option is C.

What type of function is represented in the table? exponential linear quadratic logarithmic
Answers
Answer:
quadratic
Step-by-step explanation:
Linear function is represented by the data given on the table.
What is linear equation?" Linear equation is an algebraic expression in which highest exponent of the given variables is one. It represent a straight line."
General form of linear equation
y = ax + b
According to the data given in the table,
When x = 0 , y = -3 ,
Substitute the given values of x and y in general form of linear equation
- 3 = a × 0 + b
⇒ - 3 = b ____(1)
When x = 1 , y = 5
5 = a × 1 + b
5 = a + b ____(2)
Substitute the value of b in (2) we get,
5 = a + ( -3)
⇒ a = 8
Substitute the value of 'a' and 'b' in general form of linear equation and check whether it is true for other values of x and y.
y = 8x - 3
check for the x = 2
y = 8(2) -3
⇒ y = 13
Yes , it is correct.
When x =3
y = 8 (3) - 3
⇒ y = 21
It is correct.
Hence, we conclude that Linear function is represented by the data given on the table.

X^2 - 12x + 19 in the form of (x + a)^2 + b ???
Answers
Answer:
( x-6)^2 -17
Step-by-step explanation:
X^2 - 12x + 19
we need it in given below form
(x + a)^2 + b
we know that
[tex](x + a)^2 = x^2 + 2ax + a^2\\[/tex]
lets convert that in same form
X^2 - 12x + 19 = x^2 + 2(-6)x + 19
comparing x^2 + 2(-6)x to x^2 + 2ax
we have a -6
now
(x-6)^2 = x^2 + 2(-6)x + 36
36 is missing in the x^2 + 2(-6)x + 19 hence to get that
we add and subtract 36 in the above equation
so we have
x^2 + 2(-6)x + 19 + 36 -36
rearranging it \
(x^2 + 2(-6)x + 36) -36 + 19 (x^2 + 2(-6)x + 36 =( x-6)^2)
=>( x-6)^2 -17
comparing the above equation to
(x + a)^2 + b
we have a = -6
b = -17
( x-6)^2 -17

Plz help me I don't know how to do this!!!!
Answers
Answer:
x = 25
Step-by-step explanation:
Since it is an equilateral triangle it means that all the sides are 50. Each side is equal so, if you divide 150 by 3 you get 50. (and since perimeter is the adding of each side)
Now you want to try to figure out what the altitude is of the triangle so you divide it in half. Making the bottom side length now 25 because half of 50 is 25. You now have to use Pythagoreans theorem to figure out the altitude:
c^2 - a^2 = b^2
50^2 - 25^2 = b^2
2500 - 625 = b^2
1875 = b^2
√1875 = b
43.30127019
now you put that into the expression: x√3:
x√3 = 43.30127019
x = (43.30127019) ÷ (√3)
x = 25

How many ways are there to put 5 balls in 2 boxes if the balls are distinguishable and the boxes are distinguishable?
Answers
Answer:
There are 243 ways but the balls in the boxes.
Step-by-step explanation:
There are 109375 ways to put 5 balls in 2 boxes when the balls and boxes are distinguishable by using counting principles and combinatorics
To solve this problem, use the concept of the multiplication principle, also known as the multiplication rule of counting.
Here's a step-by-step explanation:
Determine the number of choices for each ball: Since the balls are distinguishable, we have 5 choices for the first ball, 5 choices for the second ball, and so on, until we have 5 choices for the fifth ball. This can be represented as:
[tex]5 \times 5 \times 5 \times 5 \times 5.[/tex]
Determine the number of choices for each box: Since the boxes are distinguishable, each ball can be placed in either box 1 or box 2. Thus, there are 2 choices for each ball. This can be represented as:
[tex]2 \times 2 \times 2 \times 2 \times 2.[/tex]
To find the total number of ways, we multiply the number of choices for each ball with the number of choices for each box:
Total number of ways [tex]= (5 \times 5 \times5 \times5 \times5) \times(2 \times2 \times2 \times2 \times2)[/tex]
On multiply gives:
= 3125\times 32 = 109,375.
Therefore, there are 109375 ways to put 5 balls in 2 boxes when the balls and boxes are distinguishable.

HELPPPP NOW Lisa paid $35.00 to join an online music service. If she purchases 18 songs each month at a cost of $0.75 per song, what will be the total amount she has spent after 4 months?
Answers
Answer:
$54 for 4 months $89 in total
Step-by-step explanation:
Lisa paid $35 at first
then she paid 0.75 per song which is 0.75 *18 = $13.5
Then just multiply 13.5 by 4 b/c of 4 months
The total amount Liza has spent after 4 months is $89.
What is an equation?Mathematically, an equation can be defined as a statement that supports the equality of two expressions, which are connected by the equals sign “=”. For example, 2x – 5 = 13.
Given that, Lisa paid $35.00 to join an online music service, she purchases 18 songs each month at a cost of $0.75 per song,
we need to find the total amount she paid after 4 months,
So, the cost of 18 songs = 0.75 x 18 = $13.5
The cost of 18 songs in 4 months = $54
Now, the total amount she paid = $54 + $35 = $89
Hence, the total amount Liza has spent after 4 months is $89.

Suppose the population of a town is 98,000 in 2014. The population increases at a rate of 3.7 percent every year. What will the population of the town be in 2020? Round your answer to the nearest whole number.
Answers
Answer: 121871
Step-by-step explanation:
Current population = 98000
Rate of increase = 3.7% / year
Total time = 2020 - 2014 = 6 years
Population in 2020 = 98000 * (1+ (3.7/100))^6
= 98000 * (1.037)^6 = 98000 * 1.243576 = 121870.505

A, B and Care points on a circle, centre 0
Angle ABC = 389
Work out the size of angle OAC
Give a reason for each stage of your working
Answers
Answer:
m(∠OAC) = 52°
Step-by-step explanation:
A, B and C are the pints on a circle with center O.
m(∠ABC) = 38°
By the central angle theorem,
"Central angle subtended by two points on a circle measure the twice of the inscribed angle subtended by these points."
m(∠AOC) = 2m(∠ABC)
m(∠AOC) = 2 × 38° = 76°
Now in ΔAOC,
AO and OC are the radii, so the angles opposite to radii will measure the same.
∠OAC ≅ ∠OCA
Since, sum of all the interior angles of a triangle is 180°.
m(∠OAC) + m(∠OCA) + m(∠AOC) = 180°
m(∠OAC) + m(∠OAC) + 76° = 180°
2m(∠OAC) = 180° - 76°
2m(∠OAC) = 104°
m(∠OAC) = 52°
a miving company's moving rates can be represented by the function f(x)=3x+400, where x is the number of miles for the move. Another moving company's rates can be represented by the function g(x)=5x+200. Which function represents the difference between the moving companies rates , h(x)=f(x)-g(x)?

B) h(x)=-2x+200
C) h(x)=5x-200
D) h(x)=5x+600
Answers
Answer:
Option a
Step-by-step explanation:
This is a nice simple problem!
Given that the function f( x ) is equivalent to 3x + 400, respectively g( x ) = 5x + 200, all we are being asked to do is find their difference. Substitute the given values as such -
h( x ) = f( x ) - g( x )
⇒ h( x ) = ( 3x + 400 ) - ( 5x + 200 ) - Distribute negative sign, taking out ( )
⇒ h( x ) = 3x + 400 - 5x + 200 - Combine like elements
⇒ h( x ) = - 2x + 200
And there you have it! Our solution should be option a ( h( x ) = - 2x + 200 )

Marcus is saving up his money to buy a television that costs $395.50. Right now he has $85.00, and can save $29.00 each week. How many weeks will it take for Marcus to have enough money to buy the television?
Answers
Answer:
11 weeks
Step-by-step explanation:
He has 85 and can save 29 each week. This must be greater than the cost of the tv
85 + 29 w > 395.50
Subtract 85 from each side
85 -85 + 29 w > 395.50-85
29w >310.50
Divide by 29
29w/29 > 310.5/29
w >10.70689655
The number of weeks must be greater than 10.7 so rounding up
He must save for at least 11 weeks
