Answer:

1 is neither prime nor a composite number because it only has 1 divisor, 1 and 1, and it doesn't have more than 2 integral divisors, like stated, it only has 1. So it falls in neither category.

Answer:

because

Step-by-step explanation:

A prime number has exactly two integral divisors: 1 and itself. Because it contains only one divisor, the number 1 is not a prime. A whole number with more than two integral divisors is called a composite number. So, with the exception of 0 and 1, all whole integers are either prime or composite.

If one minor arc is 112°, what is the measure of the remainder of the circle?

miss Akunina [59]

Answer:

∴ The measure of the remainder of the circle = 248°

Step-by-step explanation:

∵ The measure of the circle = 360°

∵ The measure of the minor arc = 112°

∴ The measure of the remainder of the circle = 360 - 112 = 248°

Write two polynomials whose sum is x to the second power and whose difference is 1

Alex777 [14]

Answer:

Therefore, the first polynomial is:

$Z=\frac{1}{2}x^2+\frac{1}{2}\\$

the second polynomial is:

$Y=\frac{1}{2}x^2-\frac{1}{2}\\$

Step-by-step explanation:

We assume that: Z is first polynomial and Y is second polynomial.

Therefore, we have

$Z+Y=x^2\\\\Z-Y=1\\\\\implies Z+Y+Z-Y=x^2+1\\\\2Z=x^2+1\\\\Z=\frac{1}{2}x^2+\frac{1}{2}\\$

now, we get

$\implies Z+Y-Z+Y=x^2-1\\\\2Y=x^2-1\\\\Y=\frac{1}{2}x^2 -\frac{1}{2}$

Therefore, the first polynomial is:

$Z=\frac{1}{2}x^2+\frac{1}{2}\\$

the second polynomial is:

$Y=\frac{1}{2}x^2-\frac{1}{2}\\$

Two asteroids are 1000 km apart and are heading straight for each other. One asteroid is travelling at 59 km per second and the

Nataliya [291]

Answer:

10 seconds.

Step-by-step explanation:

The velocity at which they are approaching each other = 59 + 41 = 1000 km per second.

Velocity = distance / time

So time = distance / velocity

= 1000 / 100

= 10 seconds.
