Bob is diving
he is at a depth of 2 meters below sea level
sam goes down 4 times as deep
how deep is sam

depth is a negative thing because you are 2 below 0 or -2
then we mutiply -2 by 4 to get 4 times to get -8 meters below sea level

What is the exponential function property of domain?

bearhunter [10]

Answer:

The domain of exponential functions is all real numbers. The range is all real numbers greater than zero. The line y = 0 is a horizontal asymptote for all exponential functions. When a > 1: as x increases, the exponential function increases, and as x decreases, the function decreases.

The perimeter of a particular square and the circumference of a particular circle are equal. What is the ratio of the area of th

oksano4ka [1.4K]

<h2>Ratio of area of the square to the area of the circle = π/4</h2>

Step-by-step explanation:

Let the side of square be a and radius of circle be r.

The perimeter of a particular square and the circumference of a particular circle are equal.

Perimeter of square = 4 x a = 4a

Circumference of circle = 2πr

Given that

4a = 2πr

$a=\frac{\pi r}{2}$

We need to find the ratio of the area of the square to the area of the circle.

Area of the square = a²

Area of the circle = πr²

$\texttt{Ratio of area of the square to the area of the circle =}\frac{a^2}{\pi r^2}\\\\\texttt{Ratio of area of the square to the area of the circle =}\frac{\left ( \frac{\pi r}{2}\right )^2}{\pi r^2}\\\\\texttt{Ratio of area of the square to the area of the circle = }\frac{\pi}{4}$

Ratio of area of the square to the area of the circle = π/4

One angle of an isosceles triangle measures 100°. Which other angles could be in that isosceles triangle? Choose all that apply.

Ivenika [448]

Answer:

40 degrees

Step-by-step explanation:

The sum of the angles is 180.

A 100 degree angle cannot be a base angle because then

the sum of the base angles would be 200 degrees.

The 100 must be the vertex angle.

Equation:

x + x + 100 = 180

2x = 80

x = 40 degrees.

Each of the base angles is 40 degrees.
