By transformation rules, the points A₁(x, y) = (5, - 4) and A₂(x, y) = (2, - 7) are images of point A(x, y) = (2, - 3)
How to obtain the image of a point by a vector
In this problem we must determine two images associated to a given point and that are result of an transformation rule known as a translation. This transformation rule is described below:
A'(x, y) = A(x, y) + T(x, y)
Where:
A(x, y) - Original point.A'(x, y) - Image of the point.T(x, y) - Translation vector.First, write the coordinates of the original point:
A(x, y) = (2, - 3)
Second, find the images of the original point by transformation rule:
A₁(x, y) = (2, - 3) + (3, - 1)
A₁(x, y) = (5, - 4)
A₂(x, y) = (2, - 3) + (0, - 4)
A₂(x, y) = (2, - 7)

Please help me find the perimeter for the composite figure.
Answer:
A 10.28in
Step-by-step explanation:
Find the perimeter of the circle first. Because there are two half-circles, you can just find the circumference of one whole circle. 2πr is the formula. r is the radius. The circumference of the circle is 2π or 6.28.
Then add the two sides of the square. It is 2+2=4. Add 6.28 and 4.

Answer:
9)
x^2 + 2x + 1 = (x + 1)^2
10)
x^2 - 6x + 9 = (x - 3)^2
Step-by-step explanation:
To complete the square, add the square of half of the x-term coefficient.
Then use the factoring of a perfect square trinomial.
a^2 + 2ab + b^2 = (a + b)^2
a^2 - 2ab + b^2 = (a - b)^2

A survey reveals that the sales of smartphones is increasing considerably. The average annual sales of smartphones, in million units, n years after the survey is conducted is modeled by function p below. The parameter b is an unknown positive base.
p(n)=1.7×b^n
Which statement is true about this situation?
A.
When the survey was initially conducted, the average sales of smartphones was 1.7 million units.
B.
If b = 1.02, the annual sales of smartphones will double in 2 years.
C.
If b = 1.45, the annual growth rate of the sales of smartphones is 145%.
D.
The average annual sales of smartphones increases by 1.7 million units every year.
Answer:
When the survey was initially conducted, the average sales of smartphones was 1.7 million units.
Step-by-step explanation:
The exponential equation is P ( n ) = 1.7 ( b )ⁿ , where n is the number of years and P ( n ) is the annual sales of smartphones and the initial sales of smartphones was 1.7 million units
What is exponential growth factor?The exponential growth or decay formula is given by
x ( t ) = x₀ × ( 1 + r )ⁿ
x ( t ) is the value at time t
x₀ is the initial value at time t = 0.
r is the growth rate when r>0 or decay rate when r<0, in percent
t is the time in discrete intervals and selected time units
Given data ,
Let the exponential equation be represented as A
Now , the value of A is
P ( n ) = 1.7 ( b )ⁿ
where , n is the number of years
And , P ( n ) is the annual sales of smartphones
Now , the value of b is the exponential growth factor
At the initial year , the number of smartphones sold is when n = 0
So , when n = 0
P ( 0 ) = 1.7 ( b )⁰
P ( 0 ) = 1.7 million units
Hence , the number of smartphones sold in initial year is 1.7 million units

If you borrow $200 for 12 years at
an annual interest rate of 2%, how
much will you pay altogether
Step-by-step explanation:
What is the Percentage?
percentage, a relative value indicating the hundredth parts of any quantity.
Given,
If you borrow $200 for 12 years at an annual interest rate of 2%
We need to find 2% of 200.
Firstly we have to convert 2% to a decimal number by dividing by 100.
2/100=0.02
Now we have to multiply 0.02 with 200
0.02×200=4
For a month it is four.
Now we are calculating for the year
4×12=48
So now the interest amount is 48.
Now add 48 and 200
48+200
248
Hence, If you borrow $200 for 12 years at an annual interest rate of 2%, then we have to pay $248 altogether.

Constant of proportionality=
Answer:
The constant of proportionality between 'y' and 'x' in the graph is 0.75
Step-by-step explanation:
The constant of proportionality is the constant ratio between two quantities that are directly proportional.
When two quantities are directly proportional, then a percentage increase in one of the quantities will result in an equal percentage increase in the other quantity, and the two quantities are therefore, increasing at the same rate to each other
From the graph we have;
When x = 0, y = 0, all graphs of directly proportional relationships have x = 0 when y = 0
However;
When x = 2, y = 1.5
When there is an 100% increase, we have;
When x = 2 + 100/100 ×2 = 4, y = 1.5 + + 100/100 ×1.5 =3
Therefore, when x = 4, y = 3
The constant of proportionality = The ratio between each 'y' and 'x' value
∴ The constant of proportionality = y/x = 1.5/2 = 3/4 = 0.75
Therefore;
The constant of proportionality between 'y' and 'x' in the graph = 0.75.

8% of $72.60 means 0.08*72.6 which equals 5.808. 20% of $72.60 means 0.2*72.6 which equals 14.52. 14.52+5.808=20.328. 20.328+72.6=92.928 which rounds up to $92.93. I hope this helps! Have a great rest of your day!
Answer:
She paid a total of $92.93 at the salon
Step-by-step explanation:
Well it costed $72.60 but then she did the sales tax which is 8% of 72.60 and then she did a tip which was 20% of 72.60. 8% of $72.60 is 5.81 and 20% of 72.60 is 14.52. Then you would add them to get $20.33 and then you would add the $20.33 to the $72.60 to get $92.93. SO she paid a total of $92.93 at the salon.
$5.81 + $14.52 = $20.33
$20.33 + $72.60 = $92.93

Ariel is making bracelets. She bought a 15% foot long string, and a 1243 foot long string. If each
bracelet requires 42 of a foot of string, how many bracelets can Ariel make?
Answer:
She can make 55 bracelets
Step-by-step explanation:
We have the correct question as follows;
Ariel bought a 15 1/6 foot long string, and a 12 1/3 foot long string. If each bracelet requires 1/2 of a foot long string, how many bracelets can Ariel make
we have the solution as follows
Firstly, we need to find the total length of the strings bought
We can get this by adding what was bought
That would be;
15 1/6 + 12 1/3
= 91/6 + 37/3
= (91 + 74)/6 = 27 1/2 ft
From the question, each bracelet requires 1/2 ft long
so the number of 1/2 ft long bracelets we can find will be;
27 1/2 divided by 1/2
= 55/2 * 2/1
= 55
