Answer:

25% of the isles are empty

Step-by-step explanation:

48/12 is 25%

Answer:

25%

Step-by-step explanation:

12 + 12 + 12 + 12= 48

if 12 isles are empty, then that is 1/4 of 48 aka 25%

Step-by-step explanation:

Options A and D have functions that are inverses of each other.

The inverse function is defined as a function obtained by reversing the given function.

To check whether two functions are inverses of each other, we need to check if the composition of the functions in both orders results in the input value.

Here, we need to check if f(g(x))=x and g(f(x))=x for all values of x in their domains.

A. f(x) = 7/(x-9) and g(x) = (x+9)/7

f(g(x)) = f((x+9)/7) = 7/((x+9)/7 - 9) = 7/(x/7) = x, so f and g are inverses of each other.

B. f(x) = x/6 + 8 and g(x) = 6x - 8

f(g(x)) = f(6x-8) = (6x-8)/6 + 8 = x/6 + 8/6 = x/6 + 4/3, which is not equal to x. Therefore, f and g are not inverses of each other.

C. f(x) = 2 + ∛x and g(x) = 2 - x³

f(g(x)) = f(2 - x³) = 2 + ∛(2 - x³) ≠ x, so f and g are not inverses of each other.

D. f(x) = 5x - 11 and g(x) = (x+11)/5

f(g(x)) = f((x+11)/5) = 5((x+11)/5) - 11 = x, and g(f(x)) = g(5x-11) = (5x-11+11)/5 = x/5, so f and g are inverses of each other.

Therefore, only options A and D have functions that are inverses of each other.

Step-by-step explanation:

Answer:

The time it will take Jake to hit the water ia approximately 4.46 seconds

Step-by-step explanation:

The given parameters in the question are; feet

The height off the ground, of the diving board from which Jake dives, h₀ = 18 feet

g = The acceleration due to gravity

The maximum height Jake reaches, h = 26 feet

The time Jake takes to reach maximum height = 2 seconds

We have;

h = h₀ + u·t + 1/2·g·t²

v² = u² - 2·g·(h - h₀)

v = u - gt

u = gt

Where;

v = The final velocity

u = The initial velocity

t = The time taken

u = 9.81 × 2 = 19.62 m/s

The vertex form of a quadratic equation is f(x) = a(x - h)² + k², with the vertex = (h, k)

Substituting the values, gives;

26 = 18 + u·t - 1/2 × 9.81 × t²

8 = 19.62·t - 1/2 × 9.81 × t² = 19.62·t - 4.905·t²

19.62·t - 4.905·t² - 8 = 0

Therefore, the standard form is  -4.905·t² + 19.62·t - 8 = 0

The coordinate of the vertex, is (2, 8), the vertex form is therefore;

-4.905(t - 2)² + 8

2) The time it will take Jake to hit the water is given as follows;

The height at which Jake meets the water = -18 feet from initial height

∴ -4.905·t² + 19.62·t - 8 = -18

-4.905·t² + 19.62·t - 8 + 18 = 0

-4.905·t² + 19.62·t + 10 = 0

t² - 4·t - 2.04 = 0

By the quadratic formula, we have;

t = (4 ± √((-4)² - 4 × 1 × -2.04))/(2×1)

t ≈ 4.46 seconds or t ≈ -0.46 seconds

∴ t ≈ 4.46 seconds

The time it will take Jake to hit the water ≈ 4.46 seconds.

Answer:

450 minutes

Step-by-step explanation:

Given

w = 45000 - 100t

Required

Determine how long it'll take to empty the pool

Being empty means there's no water in the pool.

So, we have to set w to 0 to get the value of t

i.e w = 0

Substitute 0 for w in w = 45000 - 100t

0 = 45000 - 100t

Collect Like Terms

100t = 45000

Divide through by 100.

t = 450

Hence, it'll take 450 minutes to empty the pool

Answer:

Q = P/3

Step-by-step explanation:

Let the number of quarters be Q

Let the number of pennies be P

If the number of quarters is​ one-third the number of pennies, this can be expressed as;

Number of quarter = 1/3 of pennies

Q = 1/3 of P

Of means multiplication

The expression becomes;

Q = 1/3 × P

Q = P/3

Hence the formula relating Q to P is

Q = P/3

Answer: 13,500

Step-by-step explanation:

So the 4 is in the hundred place than u look to the right where the next digit is which is 8. If its 5 or more u round up but if its 5 or less it stays the same. So 8 is 5 or more than u round up the 4 to 5 and leave the rest of the digit 0's. but u leave the 13 the same. If that makes sense.
