Which type of transformation is shown?

Answer: B reduction

Step-by-step explanation:

The blue triangle is the pre-image. (The original image before it was changed) The green triangle is the mapped image (the image after it was changed) we know this because of the ‘ marks after each point. So the original blue triangle was reduced in size to form the green triangle.

Answer: y= 0.5x + 5.5

Step-by-step explanation: Y = mx + C

SLOPE INTERCEPT FORM:

First we need to find the slope of the two points. Which is y2-y1 / x2-x1.

8 is Y2 and 2 is Y1. 5 is Y2 and -7 is Y1. Plug those numbers into a calculator and solve. The slope (m) is 1/2 or 0.5

Then we have to find C as the slope intercept form is Y = mx + C. To find C we replace x and y with one of the points, and solve as an algebric equation. C will be 5.5

Question 1

The distance between the chords is sum of the distances between the center and the midpoint of the chords

The segments between the center to the midpoints of the chords for right triangles with one side being the radius.

The distance is:

------------------------------------------

Question 2

Midpoint of the side, the center and the vertex form a right triangle with 30° angle at the vertex.

Let the radius be r, the distance from the center to the side be h

Then we have:

As per property of 30°-60°=90° triangle, the side opposite to 30° is half of the hypotenuse. In this case, h = r/2 or r = 2h

Substitute r into equation above and solve for h:

Find the value of r:

Answer:

y = 1/12x + b

Step-by-step explanation:

So lines that are perpendicular have a negative reciprocal slope.

If line c has a slope of -12, then line d has a slope of 1/12

So y = 1/12x + b would be perpendicular to c, where b is a constant

Answer:

Step-by-step explanation:

First calculate the total number of students in all the schools:

= 618 + 378 + 204  

= 1,200 students

Use this number to calculate the proportion of the total population that a school so that this can then be used to determine the proportion of the 20 delegates they should sent.

North Middle school:  

= 618/1,200 * 20  

= 10 students

Central Middle School:  

= 378 / 1,200 * 20  

= 6 students

South Middle School:  

= 204/1,200 * 20  

= 4 students

Answer:

  s(t) = 2^(t-1)

Step-by-step explanation:

The amount in the account is the sum of the series ...

  1 + 1 +2 +4 +8 +16 +...

We note that terms after the first are a geometric sequence with a first term 1 and a common ratio 2. The sum of such a sequence is ...

  Sn = a1×(r^n -1)/(r -1) . . . . where n is the number of terms being summed

For our values, this simplifies to ...

  Sn = 1×(2^n -1)/(2 -1) = 2^n -1

We notice here that the account balance is 1 more than this sum, and that n = t-1, so the balance a(t) is ...

  s(t) = 1 +(2^(t -1) -1)

  s(t) = 2^(t -1) . . . . . . the function showing how much Jerry has

Answer:

1   1/4

Step-by-step explanation:

Just divide them, 3/4 divided by 3/5, then switch the fraction and sign.

Answer:

15/12

Step-by-step explanation:

3/4 divided by 3/5

That would become 3/4 times 5/3 because you take the reciprocal

3 x 5 = 15

4 x 3 = 12

So, 15/12 or 1.25

Answer:

5k

Step-by-step explanation:

The interest accrued on the principal is $100.

Using the formula;

A = P( 1 + r/n)^nt

A - amount

P - Principal

r = rate

n = Number of times the interest is compound

t = time in years

Substituting values;

A = 4,300( 1 + 0.023/365)365 × 1

A =  $4400

Interest =  $4400 - $4,300 = $100

The annual percentage yield is obtained from;

APY=100 (1 + r/n )n – 1

APY=100 (1 + 0.023/365)^n - 1

APY= 100(0.023)

APY= 2.3 %

Step-by-step explanation:

Use PEMDAS

Parenthesis first

6 - 3 = 3

the equation is now 4 + 8 / 2 · 3

divide 8 and 2 = 4

4 + 4 · 3

multiply 4 and 3 = 12

4 + 12

add 4 and 12 = 16

Answer:

$5.67

Step-by-step explanation:

$5.67

Markup refers to the amount added to the cost price to cover overheads and profit. So for example a 50% markup on a $10 product would mean adding 50% of $10 onto the sale price. As fractions can be written as decimals (50% = 0.5) and we are adding on the amount of markup to the initial cost we can also phrase this as 10 x 1.5 = 15  

For your question, the markup would become 1.1 and the initial cost is 2.7, remembering we must add 1 to the markup to cover the initial cost  

2.7 x 2.1 = 5.67
