Answer:

[tex]\frac{8^x}{2^y} 2y=2x^{12}[/tex]

Step-by-step explanation:

Since the numerator and denominator have a common base, this expression can be rewritten as 2(3x−y).

substitute 12 for the exponent, 3x−y and you will get A

Answer:

The answer is A [tex]2^{12}[/tex]

Step-by-step explanation:

Since 2 and 8 are both powers of 2, substituting 23 for 8 in the numerator of  

[tex]\frac{8x}{2y}[/tex]

gives you

Answer:

√10 / 10

Step-by-step explanation:

1/√10

To rationalize the denominator we need to get rid of any √ in the denominator. we do this by multiplying both sides by the square root:

1/√10 * √10/√10 = √10 / 10

Answer:

6.61 mph

Step-by-step explanation:

Speed of current; c = 2 mph

Total time to travel upstream and back; t = t1 + t2 = 4 hours

Let x represent speed of the boat in still water

Then the actual speed of the boat when going upstream is x - 2, and the actual speed when going downstream downstream is x + 2.

We know that; distance = speed x time, Thus;

For the upstream trip;

12 = (x - 2)t1

t1 = 12/(x - 2)

For the downstream trip;

12 = (x + 2)t2

t2 = 12/(x +2)

Adding both equations, we have;

t1 + t2 = (12/(x - 2)) + (12/(x +2))

4 = (12/(x - 2)) + (12/(x +2))

Multiply through by (x - 2)(x + 2)

4(x - 2)(x + 2) = 12(x + 2) + 12(x - 2)

4x²- 16 = 12x + 24 + 12x - 24

4x² - 16 = 24x

4x² - 24x - 16 = 0

Using quadratic formula, we have;

x ≈ 6.61 mph

Answer:

See Explanation (Incomplete Question)

Step-by-step explanation:

The question is incomplete as the distance of the Green tail is not given.

Given

[tex]Teams = 4[/tex]

Required

Determine the distance covered by each

Since each team would cover the same amount of distance, the distance covered by each is the total distance divided by 4.

In other words,

[tex]Each = \frac{Total\ Distance}{4}[/tex]

Assume the total distance of the green tail is 9 miles, the distance by each would be:

[tex]Each = \frac{9}{4}[/tex]

[tex]Each = 2.25\ miles[/tex]

Step-by-step explanation:

Slope (m) =ΔYΔX=12=0.5θ =arctan(ΔY)ΔX=26.565051177078°ΔX = 6 – 4 = 2ΔY = 10 – 9 = 1Distance (d) = √ΔX2 + ΔY2 = √5

= 2.2360679774998

Answer:

The value of k is 0.149.

Step-by-step explanation:

The complete question is:

In 2004, an art collector paid $84,275,000 for a particular painting. The same painting sold for $27,000 in 1950. Complete part (a) through (d)? (a) Find exponential growth rate k, to three decimal places, and determine the exponential growth function V, for which V(t) is the painting’s value, in dollars, t years after 1950.

Solution:

The exponential growth function can be expressed as follows:

[tex]y=a\cdot e^{kt}[/tex]

y = Final value after t years

a = initial value

It is provided that:

y = $84,275,000

a = $27,000

The value of t from 1950 to 2004 is, t = 54

Compute the value of k as follows:

[tex]y=a\cdot e^{kt}[/tex]

[tex]84,275,000=27,000\times e^{54k}\\\\e^{54k}=\frac{84275000}{27000}\\\\54k=\ln (\frac{84275}{27})\\\\k=\frac{1}{54}\times \ln (\frac{84275}{27})\\\\k=0.149[/tex]

Thus, the value of k is 0.149.

Answer: C

- Thompson’s insurance is cheaper even if Tara and Levi experience an incident that results in severe damage or loss to their income

Step-by-step explanation: I literally just got finished with the test, hope this helps.

Thompson’s Insurance is cheaper even if Tara and Levi experience an incident that results in severe damage or loss to their home.

Given are the information,

House valued at $425,000

AAA Insurance: $0.38 per 100 with a $500 deductible

425,000 / 100 = 4,250

4,250 x 0.38 = 1,615 annual premium

Thompson’s insurance: $0.26 per 100 with a $1000 deductible

425,000 / 100 = 4,250

4,250 x 0.26 = 1,105 annual premium

The difference we can see are :

If an incident occurs that results in damage or loss to their home, the couple shall shell out 500 before AA Insurance can take over payment for expenses.

On the other hand, the couple will shoulder 1,000 before Thompson’s insurance take over payment for expenses in the event there is an incident that results in damage or loss to their home.

Answer:

Monika gets £90

Step-by-step explanation:

Let us use the ratio method to solve this question

∵ Monika and Robert are Two factory workers

∵ They win the in-house raffle with a prize of £240

∵ Monika and Robert share the prize money in a ratio of 3: 5

→ That means the total of the ratio is equivalent to the value of the prize

∵ The total of the ratio = 3 + 5 = 8

→ By using the ratio method

→  Monika  :  Robert  : Total

→   3           :   5           :   8

→   x           :   y            :   240

→ By using the cross multiplication

∵ x × 8 = 3 × 240

∴ 8x = 720

→ Divide both sides by 8

∵ [tex]\frac{8x}{8}[/tex] = [tex]\frac{720}{8}[/tex]

∴ x = 90

∵ x represents the share of Monika

∴ Monika gets £90

Answer:

[tex]d=\sqrt{149}\approx12.21[/tex]

Step-by-step explanation:

To find the distance between any two points, we can use the distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]

We have the two points (-1, 7) and (-8, -3).

Let (-1, 7) be (x₁, y₁) and let (-8, -3) be (x₂, y₂). Substitute:

[tex]d=\sqrt{(-8-(-1))^2+(-3-7)^2}[/tex]

Evaluate:

[tex]d=\sqrt{(-8+1)^2+(-10)^2}[/tex]

Evaluate:

[tex]d=\sqrt{(-7)^2+(-10)^2}[/tex]

Square:

[tex]d=\sqrt{49+100}[/tex]

Add:

[tex]d=\sqrt{149}\approx12.21[/tex]

This cannot be simplified. Hence, the distance between (-1, 7) and (-8, -3) is √(149) or approximately 12.21 units.

Answer:

x = 30

Step-by-step explanation:

8x - 3(2x - 4) = 3(x - 6)

Distribute te -3 on the left, and the 3 on the right

8x - 3(2x - 4) = 3(x - 6)

8x - 6x + 12 = 3x - 18

Simplify

8x - 6x + 12 = 3x - 18

2x + 12 = 3x - 18

Inverse operations

2x + 12 = 3x - 18

-2x          -2x

12 = x - 18

+18     +18

30 = x
