Shape A can be transformed to shape B by a reflection in the x-axis followed by a translation (c/d). Find the value of c and the value of d

Answers

Answer:

[tex]c = -6[/tex]

[tex]d = -1[/tex]

Step-by-step explanation:

Given

See attachment for grid

Required

Find c and d

From the attachment, we have:

[tex]a = (3,5)[/tex] --- Point on A

[tex]a' = (-3,-6)[/tex] --- Corresponding point on B

When A is reflected across the x-axis, the rule is:

[tex](x,y) \to (x,-y)[/tex]

So, we have:

[tex](3,5) \to (3,-5)[/tex]

Next, is to calculate the translation from [tex](3,-5)[/tex] to [tex](-3,-6)[/tex]

This is calculated using:

[tex]3 + c = -3[/tex]

and

[tex]-5 + d = -6[/tex]

So, we have:

[tex]3 + c = -3[/tex]

[tex]c = -3-3[/tex]

---- i.e. Shift by 6 units to the left

[tex]-5 + d = -6[/tex]

[tex]d = 5 - 6[/tex]

[tex]d = -1[/tex]  --- i.e. Shift by 1 unit down

A regular polygon has an interior angle of 171 degrees. Show your work. (3 points for work, 3 points
for correct answers)
a) How many sides does it have?
b) What is the sum of the interior angles?
c) What is the measure of one of its exterior angles?

Answers

Answer:

a) 40 sides

b) 6840

c) 9 gegrees

Step-by-step explanation:

interior angle= (n-2)180

n

[tex] (n - 2)180 \div n = 171 \\ 180n - 360 = 171n \\ 180n - 171n = 360 \\ 9n = 360 \\ n = 360 \div 9 = 40 \\ [/tex]

so total number of sides is 40

b) Sum of interior angles= (n-2)×180

(40-2)×180

38×180

6840

c) Exterior angle = 360 ÷ n

360÷40 =9 degree

Miss David's birthday is in April, and she is going to have a party. She is looking to buy a bag of decorations. Each bag has two different types of decorations: balloons and streamers. The first bag has 11 balloons and 6 streamers. The second bag has 15 balloons and 4 streamers. The last bag has 6 balloons and 12 streamers. Bag 1 costs $91, bag 2 costs $99, and bag 3 costs $102. How much does each type of decoration cost?

Answers

Answer:

b = $5

s = $6

Step-by-step explanation:

this can be solved using simultaneous equation

s = streamers

b = balloons

either of the 3 equations can be used to determine the price of the items

11b + 6s = 91 equation 1

15b + 4s = 99 equation 2

multiply equation 1 by 4 and equation 2 by 6

44b + 24s = 364 eqn 3

90b + 24s = 594 eqn 4

subtract equation 3 from 4

230 = 46b

b = 5

substitute for b in eqn 1

55 + 6s = 91

s = 6

Step-by-step explanation:

Area of [tex]\triangle PQR[/tex]

From the attached image, we have:

[tex]P = (6,10)[/tex]

[tex]Q = (10,8)[/tex]

[tex]R = (6,4)[/tex]

The area is then calculated as:

[tex]A = \frac{1}{2}|(x1y2 - x2y1) + (x2y3 - x3y2) + (x3y1 - x1y3)|[/tex]

So, we have:

[tex]A = \frac{1}{2}|(6*8 - 10*10) + (10*4 - 6*8) + (6*10 - 6*4)|[/tex]

Using a calculator:

[tex]A = \frac{1}{2}|-24|[/tex]

Remove absolute bracket

[tex]A = \frac{1}{2} * 24[/tex]

[tex]A = 12[/tex]
