Answer:

Zero is even (not odd, not neutral)

Zero is neither positive nor negative (the only number with this property)

Zero is an integer (and must be considered when question limits choices to integers)

Zero is a multiple of all numbers (x*0 = 0, so a multiple of any x)

Step-by-step explanation:

Any number to the power of 0 is equal to 1. 0 is neither positive nor negative. 0 is neither prime nor composite. If you add two numbers and the sum is zero, we call the two numbers additive inverses or opposites of each other.

I need some help finding the volume of a sphere with a diameter of 18.6cm. The website says the answer I got from my calculator

Dahasolnce [82]

Answer:

Volume, V = 3367.6 cm³

Step-by-step explanation:

Given the following data;

Diameter = 18.6 cm

Radius = diameter/2 = 18.6/2 = 9.3 cm

Pie, π = 3.14

To find the volume of the sphere;

Mathematically, the volume of a sphere is given by the formula;

$Volume \; of \; a \; sphere = \frac {4}{3} \pi r^{3}$

Where;

r is the radius of the sphere.

Substituting into the formula, we have;

$V = \frac {4}{3} * 3.14 * 9.3^{3}$

$V = 4.186666667 * 804.357$

Volume, V = 3367.6 cm³

A 20 ft. ladder is used against a 15 ft. wall. What is the measure of the angle made by the ladder and the ground (nearest whole

Brrunno [24]

Step-by-step explanation:

Given that,

The length of a ladder, H = 20 feet

The height of the wall, h = 15 ft

We know that,

$\sin\theta=\dfrac{h}{H}$

h is perpendicular and H is hypotenuse

So,

$\sin\theta=\dfrac{15}{20}\\\\\theta=\sin^{-1}(\dfrac{15}{20})\\\\\theta=48.59^{\circ}$

Now using Pythagoras theoerm,

$b=\sqrt{H^2-h^2}\\\\b=\sqrt{20^2-15^2}\\\\b=13.2\ ft$

Hence, the angle made by the ladder and the ground is 48.59° and the ladder is 13.2 feet from the wall on the ground.
