Answer 1

Answer:

k=100, n=3, 1.5625, 10

Step-by-step explanation:

To find n and k, we can plug x and z in.

First we can try this for (1,100). We will get:

[tex]100=\frac{k}{1^{n} }[/tex]

Since 1 to any power is 1, we can assume that the denominator is 1 and therefore k=100.

Armed with k=100, we can plug numbers into the second equation.

[tex]12.5=\frac{100}{2^{n} }[/tex]

Moving [tex]{2^{n} }[/tex] to the left side, we get:

[tex]2^n=\frac{100}{12.5} }=8[/tex]

therefore we can solve and we see that n=3.

We can do the same for x=4, but since we have n, k, and x, we can plug these in to get z

[tex]z=\frac{100}{4^{3}} =1.5625[/tex]

We will do the same as previous but instead plug in x

[tex]\frac{1}{10}=\frac{100}{x^{3} }[/tex]

We isolate [tex]x^{3}[/tex] and get

[tex]x^{3} =1000[/tex]

Therefore x=10

Step-by-step explanation:

(2x³y^-4)^-2 = 1/(4x⁶y^‐8) = y⁸/(4x⁶)

1/(8x⁵y^-7) = y⁷/(8x⁵)

4x^-9y⁴ = 4y⁴/x⁹

so, the whole expression is then

y⁸/(4x⁶) × y⁷/(8x⁵) × 4y⁴/x⁹

4y¹⁹/(32x²⁰) = y¹⁹/(8x²⁰)

so, D is the correct answer.

A scuba diver wants to dive more than 2/12 times her previous deepest dive. That means she has to dive at least 70 feet below the surface of the ocean. This dive is represented by the inequality 2/12p<−70, where p is the distance below the surface of her previous deepest dive.


Select from the drop-down to correctly interpret the solution of this inequality.


The scuba diver's previous deepest dive was

Choose...

feet below the surface of the ocean.

Answers

The distance below the surface of her previous deepest dive is 420 feet

Given the inequality expression representing the dive given as:

2/12p<−70

We are to get the solution to the inequality expression;

Given;

2/12p<−70

Multiply both sides by 12:

2p < 70 * 12

2p < 840

Divide both sides by 2

2p/2 < 840/2

p < 420

Hence the distance below the surface of her previous deepest dive is 420 feet

A rectangle’s perimeter is 86in . Its length is 9in longer than its width. Use an equation to find the rectangle’s length and width.

Answers

Answer:

Step-by-step explanation:

Let width be x

So length would be x + 9

If perimeter is 86, then

2(l+b) = 86

2(x + x+9) = 86

4x + 18 = 86

4x = 68

X = 17

Check:

2(x + x + 9) = 86

2(17 + 17 + 9) = 86

2(43) = 86

86 = 86

By definition of f(x), we have

[tex]f\left(f^{-1}(x)right) = 6f^{-1}(x) + 4 = x[/tex]

Solve for the inverse :

[tex]6f^{-1}(x) = x - 4[/tex]

[tex]f^{-1}(x) = \dfrac{x-4}6[/tex]
