What is the term used to describe the distance of a complex number from the origin in a complex plane?
IceJOKER [234]
In a rectangular form of a complex number, where  a + bi, a and b equates to the location of the x and y respectively in a complex plane. The modulus |z| is the term used to describe the distance of a complex number from the origin. Hence, |z| = √(a²+b²)

Omgggg please please please help me I really really really need help on this. Please can you guys help me solve this problem?
Eddi Din [679]

Answer:

The volume of the figure is: 60840\pi ^3, or approximately about 191037.6 ft^3.

Step-by-step explanation:

This 3D figure can be split into two separate figures, a half-sphere, and a cone.

Let's first try to find the volume of the half-sphere.

The formula for the volume of the half-sphere is \frac{2}{3}\pi r^3, so substituting 39 for r gives us a volume of 39546\pi \\\\ft^3, or about 124174.44 ft^3.

Next, let's find the volume of the cone. We see that the radius of the cone is once again 39 ft, and the height of the cone i s just 81-39, or 42 ft.

The volume of a cone is (\pi r^2h)/3, and substituting 39 for r and 42 for h, we obtain a result of 21294\pi^3, or about 66863.16

Thus, the final volume of the figure is: 60840\pi ^3, or approximately about 191037.6 ft^3

Y=2x-4 and x+2y=10 substitute y in the second equation. what is the resulting equation
4vir4ik [10]
X + 2y = 10 becomes  x + 2(2x-4) = 10.  Thus, x + 4x - 8 = 10, and 5x = 18.

Explain how you know that 492 x 10 exponent 5 is not in scientific notation.
kozerog [31]
For it to be in scientific notation, there needs to be a decimal. 492 x 10^5 would need to be changed to 4.92 x 10^5 for it to be considered scientific notation. Whole numbers are void.
