Answer:
[tex]ln(4)+2\,\,ln(y)[/tex]
(the first option of the list)
Step-by-step explanation:
Using the properties of logarithms (first the logarithm of a product and then the logarithm of a power, we write:
[tex]ln(4\,y^2)=ln(4)+ln(y^2)=ln(4)+2\,\,ln(y)[/tex]
which agrees with the first option in the list of possible answers.

Q: How much money would you save on 10 pounds of blueberries at the less expensive fruit stand? (Hint: Find the cost of 10 pounds of blueberries for each, A and B, then subtract the values.) Remember to explain your reasoning!
Answers
Answer:
According to my...calculations, you would save $20.
Step-by-step explanation:
You have to find the ratio/the rate of change, then you multiply it to get to ten pounds. You do the same for the other line. Then you just subtract it.
A= 2 pounds for $12
B= 1 pound for $4
Multiply the two to get to 10, and whatever the number is (5) you multiply 12 by it as well. For B, you multiply by 10. You get $60, for A. $40 for B.
The amount saved would be $20.

Trevor went to the pet store to get a new pet fish. Unfortunately, the selection at the store wasn't very good. Exactly 90% of the fish at the store were goldfish. Trevor wanted any fish, but a goldfish. If there are 140 fish at the store, then how many fish could Trevor choose from?
Answers
Answer: 14 fish
explanation: 90% of 140= 126 (if u use a proportion or multiply 0.9x140).
140-126=14
Answer: He has 14 other fish to choose from in the store
Step-by-step explanation:
90% ÷ 100 = .9
.9 × 140 = 126
140 - 126 = 14

7. ET = T_F [tex]{}[/tex] CPCTE
Step-by-step explanation:
Statement [tex]{}[/tex] Reason
1. Parallelogram ABCD The given quadrilateral
2. BT = TD Based on the properties of a parallelogram, the parallelogram diagonals bisect each other
3. ∠1 = ∠2 Vertically opposite angles formed by two intersecting lines are equal
4. BC ║ AD By definition, the opposite sides of a parallelogram are parallel
5. ∠3 = ∠4 Based on the property of equality of the alternate interior angles of two parallel lines
6. Triangle BET congruent to Triangle DFT by Angle-Side-Angle rule of congruency
7. ET = T_F by Congruent Parts of Congruent Triangles are Equal, CPCTE, postulate.
The reasons that matches the statements in the two-column proof is shown in the table attached in the image below.
Recall:
Based on the, CPCTE Theorem, if two triangles are congruent, all its corresponding sides and angles of both triangles are therefore congruent together.The ASA Congruent Theorem justifies that two triangles are congruent if they have two pairs of congruent angles and a pair of included sides that are also congruent.Given parallelogram ABCD, and also, we know that EF contains T, to prove that ET = FT, establish that:
ΔBET ≅ ΔDFT by the ASA Congruence Theorem, then demonstrate that ET = FT by the CPCTE Theorem.
Therefore, the reasons that matches the statements in the two-column proof is shown in the table attached in the image below.

rode his bike two-thirds of the way to his grandma's house and then realized he
forgot the present he was going to give her. Joe rode back to his house, got the
present, and rode all the way to his grandma's house. Then he rode straight home.
How many blocks did Joe ride in all? Use labeled sketches, numbers, or words to
solve this problem. Show all your work.
Answers
Answer:
108 blocks.
Step-by-step explanation:
Joe's grandmother lives 36 blocks away from Joe.
Joe rode two thirds of the way to the house is 2/3 * 36= 24 blocks.
Then he rode back to his house (1 - 2/3) * 36= 12 blocks.
Then Joe rode back to grandma's house= 36 blocks.
Then he rode straight home= 36 blocks.
Total number of blocks he rode is 24+12+36+36= 108 blocks.

Answer:
The rate of change in the submarine's elevation is 26.0 feet per second.
Step-by-step explanation:
She begins 151 feet below sea level
Thus, her initial point is y₁ = 151 feet below sea level
i.e. at t₁=0 seconds, y₁ = 151 feet below sea level
After descending for the 3 seconds, she is 229 feet below sea level.
Thus, her second point is y₂ = 229 feet below sea level after 3 seconds
i.e. at t₂=3 seconds, y₂ = 229 feet below sea level
The rate of change is basically the slope. Thus, the rate of change can be obtained by taking the slope.
slope = rate of change = (y₂ - y₁)/(t₂ - t₁)
= (229 - 151) / (3 - 0)
= 78/3
= 26.0
Therefore, the rate of change in the submarine's elevation is 26.0 feet per second.

Makayla borrows $15200. Some is from her friend at 5% annual interest, 2 times as much as that from her bank at 8% , and the remainder from her insurance company at 4%. She pays a total of $968 in interest for the first year. How much did she borrow from each source?
Answers
Answer:
Amount borrowed from friend = 4000
From Bank = 8000
From insurance = 3200
Step-by-step explanation:
Given that:
Amount borrowed = $15200
Let amount borrowed from friend = x
x at 5% = 0.05x
From Bank = 2x at 8% = 0.08*2x = 0.16x
From insurance = 15200 - (x + 2x) at 4%
From insurance = 15200 - 3x at 4% ; (15200 - 3x)* 0.04 = 608 - 0.12x
Interest paid in first year = $968
Simple interest = principal * rate * time
968 =
968 = (0.05x + 0.16x + 608 - 0.12x)
968 - 608 = 0.05x + 0.16x - 0.12x
360 = 0.09x
x = 360 / 0.09
x = 4000
Hence,
Amount borrowed from friend = 4000
From Bank = 2x = 4000 * 2 = 8000
From insurance = 15200 - (4000 + 8000) = 3200
x + 1 - x = 1

One number is three less than a second number. Six times the first is 6 more than 3 times the second. Find the numbers.
Answers
Step-by-step explanation:
Given,
x = y - 3
Also,
6(y - 3) = 3y + 6
6y - 18 = 3y + 6
6y - 3y = 6 + 18
3y = 24
y = 24/3
y = 8
x = 8 - 3
x = 5
Therefore, the first number is 5 and the second number is 8.
