Answer:

Average breath hold time by hippo under water ≥ 5 minutes

Step-by-step explanation:

Average time by human = 1 minute

Average time by hippo = ≥ 5 times human

Since average human breath hold time = 1 minute

Average breath hold time by hippo = 5 * 1 minute

Average breath hold time by hippo under water ≥ 5 minutes

What is the distance between (-15,1) and (-15,6)
Vladimir [108]

Answer:

So you would use the distance formula which is the square root of (x2-x1)^2 + (y2-y1).

Step-by-step explanation:

So it would be the square root of (-15-(-15)^2 + (6-1)^2

(-15-(15)^2 is the same thing as (-15+15)^2.

(-15+15)^2 is equal to 0^2 which is, 0.

(6-1)^2 is equal to 5^2, which is 25.

So the square root of 0 + 25 is the same thing as radical 25.

Radical 25 is equal to 5.

So, the final answer is 5.

The circumference of a pizza is about 38 inches. What is the diameter of the pizza? Round to the nearest tenth if necessary
anygoal [31]

Answer:

The diameter of the pizza is 12 inches

Step-by-step explanation:

Given:

Circumference of a pizza = 38 inches

To Find:

The Diameter of the pizza =?

Solution:

Circumference:

The distance around the edge of a circle (or any curvy shape). It is a type of perimeter.

We know that the shape of the pizza is circle.

So the given circumference is circumference of a circle.

Now,

Circumference of the circle(pizza)=2\pi r

where r is the radius of the circle

circumference of the pizza =38

Thus

2\pi r= 38

\pi r=\frac{38}{2}

\pi r=19

r=\frac{19}{3.14}

r=6.050 inches

Now,

Diameter = 2\times r

Diameter = 2\times 6.05

Diameter=12.1 inches

Rounding to the nearest tenth

Diameter=12 inches

8.<br> f(x) = -0.75x<br> find the inverse function f-1(x) for the given functions f(x)
olasank [31]

Answer:

\frac{x}{-0.75}=y

Step-by-step explanation:

To find the inverse of a function, you switch the x and y values and solve for y. (keep in mind that f(x) is just another way of writing y)

y=-0.75x\\x=-0.75y\\\frac{x}{-0.75}=y

so \frac{x}{-0.75}=y is our answer
