3. Consider this dilation Complete sentences
(a) is the image of the dilation a reduction or an enlargement of the original figure? Explain
(b) What is the scale factor? Explain
Answer
Answers
Answer:
a) A reduction
b) The scale factor is 1/2
Step-by-step explanation:
The vertices of the original figure, ABCD are;
A(-2, 4), B(4, 4), C(2, -2), and D(-4, -2)
The vertices of the image, A'B'C'D' are;
A'(-1, 2), B'(2, 2), C'(1, -1), and D'(-2, -1)
a) The length of the side AB = 4 - (-2) = 6 (Distance between points having the same 'x' or 'y' coordinates
The length of the side A'B' = 2 - (-1) = 3
The length of AB = 6 is larger than the length of A'B' = 3, therefore the image A'B'C'D' is a reduction of (is smaller) the figure ABCD
b) The scale factor = The ratio of the lengths corresponding sides of the image to the original figure;
∴ The scale factor =A'B'/AB = A'D'/AD = B'C'/BC = D'C'/DC
AD = √((-4 - (-2))² + (-2 - 4)²) = 2·√10
A'D' = √((-2 - (-1))² + (-1 - 2)²) = √10
A'D'/AD= √10/(2·√10) = 1/2
Therefore, given that the coordinates of the preimage are 2 × the coordinates of the image, we have;
The scale factor = A'B'/AB = B'C'/BC = D'C'/DC = A'D'/AD =1/2
The scale factor is 1/2, therefore, we multiply the dimensions of the original figure by 1/2 to get the dimensions of the image.
The scale factor = 1/2.

Mitchell went on a shopping trip to Kensington. He purchased a pair of headphones originally
priced at $50 but discounted 60%. If sales tax in Kensington is 15%, what was the total cost?
Answers
= 30
$50-$30=$20
20x(15/100)
= $3
$20+$3 = $23
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
The total cost of the pair of headphones is $23.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/200 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
105 = 10/100 = 1/10
We have,
Original price of the headphones = $50
60% of $50
= 60/100 x 50
= $30
The price of the headphones after the discount.
= $50 - $20
= $20
The amount of sales tax.
= 15% of $20
= 15/100 x 20
= $3
The total cost.
= $20 + $3
= $23
Thus,
The total cost of the pair of headphones is $23.

A bicycle store costs $2800 per month to operate. The store pays an average of $50 per bike. The average selling price of each bicycle is $90. How many bicycles
must the store sell each month to break even?
The store must sell bicycles each month to break even.
(Type a whole number.)
Answers
Answer:
70 Bikes
Step-by-step explanation:
[using b as a variable for bikes]
2800=-50b+90b
[2800 is total cost of store with-50 being cost per bike and 90 being selling point of bike]
2800=40b [simplified by combining -50 with 90]
70=b [divided 2800 by 40 to get the break even for the store]
Anchor: If you start with 50 g of a material, how much is half of that? How much is half of half? How much is half of that?
Answers
Answer:
Step-by-step explanation:
1/2 of 50 grams is the same thing as 50 divided by 2 which is 25
Now you take 1/2 of 25 grams. That's 25 divided by 2. Use your calculator if you're not sure 25 divided by 2 = 12 and 1/2 or 12.5
I think we're down to 1/2 of 12.5
1/2 of 12.5 is 6 and then 0.5/2 which is 0.25
So 1/2 of 12.5 is 6.25
If I left one out, leave a comment.
Just in case 1/2 of 6.25 = 6/2 = 3
1/2 of 0.25 = 0.25/2 = 0.125
so the answer here is 3.125
If I've misunderstood the question, leave a note for that too.

Timia needs so cash in a hurry she owns her car outright and is considering a title loan. The lender told timia she could borrow 1750 for 1 month
Answers
The question is incomplete ; the fee which Timia would pay isn't given. And this is needed to compute the APR on the loan.
I would assume that the fee which Timia would pay as interest on the 1 - month loan is x
Answer:
r = x / 145.83333
Step-by-step explanation:
If interest paid, I = x
Principal, P = $1750
And period (time) of loan = 1 month = (1/12) = 0.0833333
Rate = r
Using the simple interest formula :
Interest = Principal * rate * time
x = 1750 * r * 0.833333
Make r the subject :
x = 145.83333r
Divide both sides by 145.83333
Hence, the rate value , r becomes :
r = x / 145.83333
Therefore, the student can just input the appropriate, interest value in place of x and obtain the correct and exact answer (I do not want to use an hypothetical value for x) .

determine the value of k if g(x) =4x+k is a tangent to f(x)= -x² +8x +20
Answers
Answer:
22
Step-by-step explanation:
222
The value of k in the given functions is; 24
What is the value of the function to the tangent?
We are given the functions;
g(x) = 4x + k as a tangent to f(x) = -x² +8x +20
For f(x) = -x² +8x +20
=> f'(x) = -2x + 8
Thus, slope of tangent at ( x , y) = -2x + 8
For g(x) = 4x + k
g'(x) = 4.
Thus, slope is 4
Therefore;
-2x + 8 = 4
-2x = -4
x = 2
Putting 2 for x in f(x) gives;
f(2) = -2² + 8(2) + 20
f(2) = 32
Thus, it is at (2 , 32)
Thus, (2 , 32) lies on g(x) = 4x + k
4(2) + k = 32
k = 32 - 8
k = 24
