Answer 1

Answer:

3

Step-by-step explanation:

=> y= log _5 125

=> y = log _5 5³

Using properties of log ,

=> y = 3 log_5 5

= > y = 3*1

=> y= 3

Answer 2
Solution:

[tex]y = log_{5}(125) \\ = > y = log_{5}( {5}^{3} ) \\ = > y = 3 log_{5}(5) \\ = > y = 3 \times 1 \\ = > y = 3[/tex]

Answer:

y = 3

Answer:

Slope = -2

Step-by-step explanation:

Given the two points, (-4, 10) and (0, 2), the error in the given problem is the incorrect substitution of values into the formula. It should have been formatted as follows:

Let (x₁, y₁) = (-4, 10)

    (x₂, y₂) = (0, 2)

The formula for solving for the slope of the line is:

m = (y₂ - y₁)/(x₂ - x₁)

where m represents the slope of the line.

Substitute the given values into the formula to solve for the slope:

m = (y₂ - y₁)/(x₂ - x₁)

[tex]m = \frac{2 - 10}{0 - (-4)}[/tex]

[tex]m = \frac{-8}{0 + 4 }[/tex]

m = -8/4

m = -2

Therefore, the slope of the line is -2.

1. A shopkeeper buys a stove from a manufacturer. The shopkeeper sells the stove for $2700 at a profit of 25%.
(a) What is the cost price of the stove to the shopkeeper from the manufacturer? (4 marks)
(b) If the shopkeeper gives a 15% discount for cash, how much money does a customer pay for the stove?​

Answers

Answer:

a.divide the amount by the percentage.

$2700× 25%

Ans:$675

subtract the selling price from the profit.

$2700 - $675

Ans:$2025

b.divide the 15% from selling price.

$2700 × 15%

Ans: 405

deduct the selling from from the discount given.

$2700 - $405

Ans: $2,295

what’s the answer to this?

Answers

Your answer would be c y=4x+2. Based on the formula y= Mx+b, b being your y intercept, the line starts on 4. This equation is the only one that adds four to it therefore it is c. We can also prove with the slope. The slope is rise over run, ( m is the slope). Moving 4 up and 1 to the right, the line is created, making this equation true and the correct answer.

A tree that was 30 meters high was broken so that the broken part was 7 times the length of the part that was left
standing. Find the length of each part.
Please help step by step please

Answers

Answer:

Broken = 7x

Step-by-step explanation:

Left = x

x(7x) = 30

(7x² = 30)⅐

x² = 4.285

√x² = √4.285

x = 2.07

Left = 2.07 meters

Broken = 7 x 2.07 = 14.49 meters

i hope this is correct!

A system of equations is shown. x = 10 3x + 5y = 20

Answers

Answer:

(10, - 2 )

Step-by-step explanation:

x = 10 → (1)

3x + 5y = 20 → (2)

Substitute x = 10 into (2)

3(10) + 5y = 20

30 + 5y = 20 ( subtract 30 from both sides )

5y = - 10 ( divide both sides by 5 )

y = - 2

solution is (10, - 2 )

How you calculate this is this:

So, any two given sides much be greater than the other side.

7. The answer is no. 1 plus 5 is 6 right? 6 is less than 11, so it can never be a triangle.

8. The answer is yes. 3 plus 6 is greater than 7. 3 plus 7 is greater than 6. 6 plus 7 is greater than 3.

9. The answer is yes. 9 plus 11 is greater than 12. 9 plus 12 is greater than 11. 11 plus 12 is greater than 9.

The manager of a 100-unit apartment complex knows from experience that all units will be occupied if the rent is $500 per month. A market survey suggests that, on average, one additional unit will remain vacant for each $10 increase in rent. What rent should the manager charge to maximize revenue?

Answers

Answer:

750$

Step-by-step explanation:

lets say the increase is x times 10$. it means manager asks for (500+10x) and earns it from (100-x) apartments. Revenue will be the product of the two:

[tex](500 + 10x)(100 - x) = 50 \: 000 - 500x + 1 \: 000x - 10 {x}^{2} = 50000 + 500x - 10 {x}^{2} [/tex]

its a parabola, and its maximum is on the vertex, or at

[tex]x = - \frac{b}{2a} = - \frac{500}{ - 20} = 25[/tex]

so he should add 10$ 25 times, or ask 750$
