Answer: A''=(-2, 2)
Step-by-step explanation:
A' = (2, -(-2)) = (2,2) ==> the y-coordinate is negated when A reflects over the y-axis
A''=(-(2), 2) = (-2, 2). ==> the x-coordinate is negated when A reflects over the x-axis
A''=(-2, 2)

Answer:
With a circle with radius 7 cm, the circumference of given circle is 14π (cm) and the area is 49π (cm²).
Step-by-step explanation:
Given: radius = 7 cm
Circumference of a circle: C = 2πr
C = 2πr
Substitute given value radius.
C = 2π(7)
Multiply 7 and 2.
C = 14π cm.
Area of a circle: A = πr²
A = πr²
Substitute given value radius.
A = π(7)²
Square the 7.
A = 49π cm²

MODELING REAL LIFE Bowling alley A charges $3.75 to rent shoes and $4 per game. Bowling alley B charges $2.50 to rent shoes and $4.50 per game. a. For what numbers of games is the total cost, including a pair of rental shoes, less at bowling alley A? at bowling alley B? Bowling alley A: ___ or more games. Bowling alley B: ___ or___ games .
b. Bowling alley A increases the cost per game by $0.50. How does this affect your answer in part (a)? Explain.
The numbers of games that makes the total cost, including a pair of rental shoes, less at bowling alley A is;
Bowling alley A: 5 or more games.
How to solve inequality word problems?Bowling alley A;
Their charges per game is $4 per game
Charges to rent shoes is $3.75
If number of games is x, then we have;
Total Cost = 3.75 + 4x
Bowling alley B;
Their charges per game is $4.50 per game
Charges to rent shoes is $2.50
If number of games is x, then we have;
Total Cost = 2.5 + 4.5x
Now, for the total cost, including a pair of rental shoes, less at bowling alley A, it means that;
2.5 + 4.5x > 3.75 + 4x
Rearrange to get like terms gives;
4.5x - 4x > 3.75 - 2.5
0.4x > 1.25
x > 1.25/0.4
x > 3.125
Thus, the numbers of games that makes the total cost, including a pair of rental shoes, less at bowling alley A is;
Bowling alley A: 5 or more games.
B) Bowling alley A increases the cost per game by $0.50. Thus, the inequality is now;
3.75 + 4.5x > 2.5 + 4.5x
This means that the total cost will now always be greater at Bowling alley A

Write 0.641 as a fraction in simplest form
Write the number as a fraction of 1 (one):
0.641 = 0.641/1Simultaneously multiply the numerator and denominator by 10 as many times as the digits after the comma (separation between the integer part and the fractional part of the number):
Since we have 3 numbers after the comma, multiply the numerator and denominator by 1000. So,
0.641/1 = (0.641 x 1,000)/(1 x 1,000) = 641/1,000.Note that multiplying by 10 is the same as moving the decimal point one place to the right.
Once this fraction is irreducible, that is, it is in reduced form, we can no longer simplify it. The answer is the previous fraction.

Andres Michael bought a new boat. He took out a loan for $24,440 at 3.75% interest for 4 years. He made a $4,410 partial payment at 4 months and another partial payment of $2,590 at 8 months. How much is due at maturity?
The amount due at maturity on Andres Michael's loan of interest rate of 3.75% is $20,431.75
What is effective monthly loan interest rate?
The loan effective monthly interest rate can be determined as the annual interest rate of 3.75% divided by 12 since there are 12 months in a year
effective monthly interest rate=3.75%/12
effective monthly interest rate=0.003125
loan balance after 4 months=$24,440*(1+0.003125)^4- $4,410
loan balance after 4 months=$20,336.94
loan balance after 12 months=$20,336.94*(1+0.003125)^8-$2,590

Given: 13, 18, 23, 28
We add 5 to each number
13 + 5 = 18
18 + 5 = 23
23 + 5 = 28

Given : 512, 256, 128, 64
Divide each number by 2
512 ÷ 2 =256
256 ÷ 2 = 128
128 ÷ 2 = 64

a cuckoo clock has birds that pop out of their nests every 6 minutes and dancers that pop out every 15 minutes. the birds and dancers have just popped out at the same time. when will this happen again in the next 60 minutes?
We get that the birds and the dancers will clock out again in 30 minutes.
We are given that:
a cuckoo clock has birds that pop out of their nests every 6 minutes.
And the dancers that pop out every 15 minutes.
Now, they have popped out the same time. For this to happen again, we will find the LCM of 6 and 15.
6 = 2 × 3
15 = 3 × 5
LCM = 2 × 3 × 5
LCM = 3 × 10
LCM = 30
So, they will pop out again after 30 minutes.
