What would be the new coordinates of the figure below if it is translated the figure 4 units horizontally and -2 units vertically?
Answers
Given the coordinates of recatangle ABCD:
A(-3, 1), B(2, 1), C(2, -2), D(-3, -2)
Let's find the new coordinates after the rectangle is translated 4 units horizontally and -2 units vertically.
Let's apply rules of translation.
A translation 4 units horizontally means a shift 4 units to the right.
It is written as: (x + 4)
A translation -2 units vertically means a shift 2 units downwards.
It is written as: (y - 2)
Thus, to find the new coordinates, add 4 to the x-coordinates and subtract 2 from the y-cooridnates.
We have the translation rule: (x + 4, y - 2)
We have:
A(-3, 1) ==> (-3 + 4, 1 - 2) ==> A'(1, -1)
B(2, 1) ==> (2 + 4, 1 - 2) ==> B'(6, -1)
C(2, -2) ==> (2 + 4, -2 - 2) ==> C'(6, -4)
D(-3, -2) ==> (-3 + 4, -2 - 2) ==> (1, -4)
Therefore, the new coordintes of the figure are:
A'(1, -1), B'(6, -1), C'(6, -4), D(1, -4)
ANSWER:
A'(1, -1), B'(6, -1), C'(6, -4), D'(1, -4)

Kita Ramin obtained a $3,000 loan to pay for a used car. She agreed to make 12 monthly payments of $266.22. What is the APR?
Answers
Answer:
APR = 6.5%
Explanation:
If Kita makes 12 payments of $266.22, the maturity value of the loan will be equal to:
V = 12 x $266.22 = $3194.64
On the other hand, the maturity value is equal to:
[tex]V=P(1+r\cdot t)[/tex]Where P is the initial amount, r is the Annual Percentage Rate APR and t is the time in years. So, replacing V by $3194.64, P by $3000, and t by 1 year (12 months), we get:
[tex]\begin{gathered} 3194.64=3000(1+r\cdot1) \\ 3194.64=3000(1+r) \end{gathered}[/tex]Now, we can solve for r as:
[tex]\begin{gathered} \frac{3194.64}{3000}=\frac{3000(1+r)}{3000} \\ 1.065=1+r \\ 1.065-1=1+r-1 \\ 0.065=r \end{gathered}[/tex]So, the annual percentage rate is 0.065 or 6.5%
A local health clinic surveys its patients about their waterdrinking habits. It found the data is normally distributed,the mean amount of water consumed daily is 62 ounces, andthe standard deviation is 5.2. How much water, in ounces,do approximately 95% of the patients drink each day?A: 56.8 to 67.2B: 54.2 to 69.8C: 51.6 to 72.4D: 41.2 to 62.0
Answers
In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data:
water drinking habits:
mean = 62 ounces
standard deviation = 5.2 ounces
Step 02:
normally distribution:
95% ===> 2 SD
(62 + 5.2 + 5.2) ounces = 72.4 ounces ==> + 2 SD
(62 - 5.2 - 5.2) ounces = 51.6 ounces ==> - 2 SD
The answer is:
51.6 ounces - 72.4 ounces

Answers
Given:
a4 = 98
a5 = 99.2
a6 = 100.4
a7 = 101.6
a8 = 102.8
Use the arithmetic sequence formula below:
[tex]a_n=a_1+(n-1)d[/tex]Where,
an = nth term
a1 = first term
n = number of terms
d = common differnce
Let's solve for the common differnce.
d = a5 - a4 = 99.2 - 98 = 1.2
Use the 8th term a8, to find the first term:
[tex]\begin{gathered} 102.8=a_1+(8-1)1.2_{} \\ \\ 102.8=a_1+(7)1.2 \\ \\ 102.8=a_1+8.4 \\ \\ a_1=102.8-8.4\text{ = 94.4} \end{gathered}[/tex]Therefore, the first term a1 = 94.4
Thus, the equation for the nth term will be:
Input 94.4 for a1, 1.2 for d in the arithmetic formula above
[tex]\begin{gathered} a_n=94.4+(n-1)1.2 \\ \\ a_n=94.4+1.2n-1.2 \\ \\ \text{combine like terms:} \\ a_n=1.2n+94.4-1.2 \\ \\ a_n=1.2n+93.2 \end{gathered}[/tex]ANSWER:

1 ) According to the question, the temperature has been changing according to this function:
[tex]r(t)\text{ =}3.27\text{ }\cos (\frac{\pi t}{12})+0.049[/tex]Where t is the number of hours after 6:00 am last Sunday
b) From 6 am to 1 pm last Sunday, the temperature in the park increased by
6 am to 1 pm = 7 hours, let's plug into that:
[tex]\begin{gathered} r(t)\text{ =}3.27\text{ }\cos (\frac{\pi t}{12})+0.049 \\ r(7)\text{ =}3.27\text{ }\cos (\frac{7\pi}{12})+0.049 \\ r(7)=3.31732 \\ r(7)\approx3.32 \end{gathered}[/tex]The rate of change in 7 hours was approximately 3.32 degrees per hour
c)
The temperature in the park at 6 am was 43.4 ºF. To find the temperature we must find the value for y, 1 pm Last Sunday. Let's plug the value already found: 1.68 for r.
Considering that according to question a, the temperature increased by 1.68º per hour. 6 am to 10 pm: 4 hours
c)
Since the question wants the temperature from 6 am to 1 pm, and it has been increasing by 3.32 degrees per hour, in 7 hours
7 x 3.32 =23.24º
43.4º+23.24=110.04ºF

Given the following information:

This occurs in the fourth quadrant. This also means that the value of tan is negative.
We know that sin uses the value of the opposite and the hypotenuse.

Answers
Answer
$1,016,699
Explanation
The amount, A that an invested sum of P, becomes over time t, at a rate of r% is given as
A = P (1 + r)ᵗ
For this question,
A = Total amount that the amount invested becomes = $80,000 × 25 = $2,000,000
P = Amount invested at the start of the 10 years before retirement = ?
r = 7% = 0.07
t = 10 years
A = P (1 + r)ᵗ
2,000,000 = P (1 + 0.07)¹⁰
2,000,000 = P (1.07)¹⁰
Note that 1.07¹⁰ = 1.967
2,000,000 = 1.967P
We can rewrite this as
1.967P = 2,000,000
Divide both sides by 1.967
(1.967P/1.967) = (2,000,000/1.967)
P = $1,016,699

What is area and circumference of circle?
Area of the circle is the total space taken by the circle.
Circumference of the circle is the length of the boundary of the circle.

We have two numbers x and y such that their difference is 12:
[tex]\begin{gathered} x-y=12 \\ \Rightarrow x=12+y \end{gathered}[/tex]Now, we take the product of them:
[tex]x\cdot y=(12+y)\cdot y=y^2+12y[/tex]The smallest result we can get is 0 (ignoring the negative numbers, because the meaning of "small" implies an absolute value). Looking at the expression above, it is 0 for y = 0. If y = 0 then x = 12, and the difference is:
[tex]x-y=12-0=12[/tex]And their product is:
[tex]x\cdot y=12\cdot0=0[/tex]2v – 5V = -24muti step equation
Answers
2v - 5v = -24
2v - 5v = -3v, then
-3v = -24
-3 is multiplying on the left, then it will divide on the right
v = -24/(-3)
v = 8
suppose you have 5 apples and you subtract 2 of them, how many apples are left?
You are doing the next computation: 5 apples - 2 apples = 3 apples
What is the result of 2 apples - 5 apples?
Use the formula P = 2l + 2w to find the length l of a rectangular lot if the width w is 55 feet and the perimeter P is 260 feet.l = ? feet
Answers
In order to determine the length of the given rectangle, Solve the equation for the perimeter of the rectangle for l and replace w=55ft and P=260ft, and simplify:
[tex]\begin{gathered} P=2l+2w \\ 2l=P-2w \\ l=\frac{P-2w}{2} \\ l=\frac{260ft-2(55ft)}{2} \\ l=\frac{260ft-110ft}{2} \\ l=\frac{150ft}{2}=75ft \end{gathered}[/tex]Hence, the length of the rectangle is 75ft
