Answer:

Jack is incorrect. The correct answer is 2

Step-by-step explanation:

The question is given as:

4x-24 / (y+w) where x=5, y=3 and w= -5

Substitute values of x, y and w in the equation as;

4*5 - 24 / (3+-5)

20 - 24 / (-2)

-4 / -2 = 2

Jack's answer is 7 which is wrong. The correct answer is 2

2 is correct because you have substituted the real values of x,y and w in the expression and performed the operation right.

What percent of 25 is 12?

snow_lady [41]

12 * 4 = 48
25 * 4 = 100

48/100 = 0.48, or 48%

12 is 48% of 25
I hope this helps you

Can a prime number be a multiple of any other number except itself. Explain why or why not

zzz [600]

No, by definition a prime number is one where the only factors are 1 and itself. If some prime number is a multiple of another number, then that other number is a factor of the prime number. But that would make it composite (non-prime)

For example, the number 11 is prime. The only factors are 1 and itself. If we made the claim that 11 is a multiple of 2, then 2 would be a factor of 11 making 11 non-prime (as it doesn't just have 1 and itself as factors).

Note: If you have two numbers A and B, and you say that A is a factor of B, then A is the smaller value. Though there is the exception when A = B. For example, saying "8 is a factor of 16" has 8 being the smaller value.

Another note: if you say "A is a multiple of B", then B is larger than A. The exception is when A = B. Example: "100 is a multiple of 5"

Use polar coordinates to find the volume of the given solid. Inside both the cylinder x2 y2 = 1 and the ellipsoid 4x2 4y2 z2 = 6

Anton [14]

The Volume of the given solid using polar coordinate is: $\frac{-1}{6} \int\limits^{2\pi}_ {0} [(60) ^{3/2} \; -(64) ^{3/2} ] d\theta$

V= $\frac{-1}{6} \int\limits^{2\pi}_ {0} [(60) ^{3/2} \; -(64) ^{3/2} ] d\theta$

<h3>What is Volume of Solid in polar coordinates?</h3>

To find the volume in polar coordinates bounded above by a surface z=f(r,θ) over a region on the xy-plane, use a double integral in polar coordinates.

Consider the cylinder, $x^{2}+y^{2} =1$ and the ellipsoid, $4x^{2}+ 4y^{2} + z^{2} =64$
