Answer:
Reflection: A' (5, 3)
B' (2, 3)
C' (2, 1)
D' (5, 1)
Dialation: A"(10, 6)
B" (4, 6)
C" (4, 2)
D" (10, 2)
Step-by-step explanation:
A(−5,3),B(−2,3),C(−2,1),D(−5,1)
To reflect over the y-axis you change the value of x. In this case all of the values for x are negative. You turn them all into a positive.:
A' (5, 3)
B' (2, 3)
C' (2, 1)
D' (5, 1)
To dialate by a scale factor of 2 you multiple everything by 2 and you should get: A"(10, 6)
B" (4, 6)
C" (4, 2)
D" (10, 2)

Valeria already has $65 dollars in her savings account. If she puts $5 per week in her account, write and solve an inequality to find out how many weeks she must save to have at least $200 in her account.
Answer:
65 + 5x ≥200
Step-by-step explanation:
Hi, to answer this question we have to write an inequality with the information given:
Janice's savings (65) plus the product of the amount she saves per week (5) and the number of weeks (x) must be higher or equal to $200.
Mathematically speaking:
65 + 5x ≥200
If we solve it for x:
5x ≥200-65
5x ≥135
x ≥ 135/5
x ≥ 27 weeks

Now add the populations in scientific notation.
Rewrite each estimate so they all have the same power of 10.
Dogs: 69,900,000
Cats: 36,100,000
Birds: 8,300,000
Answer:
question 1 part a =
estimated number of dogs
=6.99 × 107
= 6.99 • 10,000,000
= 69,900,000
estimated number of cats
= 3.61 × 107
= 3.61 • 10,000,000
=36,100,000
estimated number of birds
= 8.3 × 106
= 8.3 • 1,000,000
= 8,300,000
part b = total population of pet dogs, cats, and birds
= 69,900,000 + 36,100,000 + 8,300,000
= 114,300,000
question 2 part a =
The estimated number of dogs is 6.99 x 10^7 .
The estimated number of cats is 3.61 x 10^7.
The estimated number of birds is 8.3 x 10^6.
The power of 10 in 8.3 x 10^6 is 6, which is less than the power of 10 in the other two numbers. To make the calculation simpler, convert this number so the exponents are all the same.
Multiply and divide 8.3 x 10^6 by 10 to increase its exponent by 1:
8.3 x 10^6 = 10/10 x 8.3 x 10^6
= 8.3/10 x 10^6 x 10
= 0.83 x 10^7
part b =
total number of pet dogs, cats, and birds
=
6.99 × 107 + 3.61 × 107 + 0.87 × 107
=
(6.99 + 3.61 + 0.83) • 107
=
11.43 • 107
part c =
No. The sum from part B is not in scientific notation.
The total number of pet dogs, cats, and birds is 11,43 x 10^7. To express the number in scientific notation, the decimal point must be moved one digit to the left. To do that, divide and multiply the number by 10:
10/10 x 11.43 x 10^7 = 11.43/10 x 10^7 x 10
= 1.143 x 10^8
Written in scientific notation, the total number of pet dogs, cats, and birds is 1.143 x 10^8.
question c = They are the same. If you convert the number in standard form from question 1 to scientific notation, it is the same as the number in scientific notation found in question 2.

Cats: 3.61 x [tex]10^8[/tex]
Birds:0.083 x [tex]10^8[/tex]
What is Scientific Notation?Scientific notation is a method of displaying very large or very small numbers in a more simplified format. We know that entire numbers can be extended indefinitely, but such large numbers cannot be written on a piece of paper. Also, the numbers in the millions place after the decimal required to be represented in a simpler format. As a result, representing a few integers in their expanded form is challenging. As a result, we employ scientific notation.
Given:
We have to change the number in Scientific Notation in which only one significant number will be before the decimal and remaindering raise to power of 10.
First, Dogs: 69,900,000 whose Scientific Notation is
= 6.99 x [tex]10^8[/tex]
Second, Cats: 36,100,000 whose Scientific Notation is
= 3.61 x [tex]10^8[/tex]
Third, Birds: 8,300,000 whose Scientific Notation is
= 8.3 x [tex]10^6[/tex]

Two questions can you please answer correctly.
Answer:
First question: D. 6.28 ft
Second question: C. Rectangle
Step-by-step explanation:
The circumference of the circle is 6.28 ft. The first thing you do to find the circumference for this circle is find what the radius is. Since the diameter is equal to 2 times radius, and the diameter is 2, we know that the radius is one. Now, we can find the circumference. To find it, the formula is 2 times π times radius. For this problem, we use π for 3.14 and the radius for 2. In this case, 2 times 3.14 times 1 is equal to 6.28. Therefore, the circumference of this circle is equal to 6.28.
