Answer:

Step-by-step explanation:

The leading coefficient is the coefficient with a variable with the greatest exponent.The exponent is the number you would say "the power to". What I mean is let's say you have this number: $3^{2}$ . The exponent would be 2 in this equation because it's saying what power 3 is too. Therefore, 5 is the leading coefficient.

Find the volume of a cone with a base area 36pi and a height equal to twice the radius

beks73 [17]

The volume of a cone is $V= \frac{1}{3} A_{\text{basis}}\cdot H$ . Since $A_{\text{basis}}=36\pi$ and you know that basis is a circle you can conclude that $\pi R^2=36\pi$ and $R=6$ .

If height $H$ equal to twice the radius $R$ , then $H=2R=2\cdot 6=12$ .

The volume will be: $V= \frac{1}{3} \cdot 36\pi \12=144\pi$ cubic units.

How many positive integers can be expressed ad a product of two or more of the prime numbers 5,7,11,and 13 if no one product is

sertanlavr [38]

Answer:

11 positive integers can be expressed.

Step-by-step explanation:

Consider the provided information.

The number of possible prime numbers are 5,7,11,and 13.

There are 4 possible prime numbers.

How many positive integers can be expressed as a product of two or more of the prime numbers, that means there can be product of two numbers, three number or four numbers.

The formula to calculate combinations is: $^nC_r=\frac{n!}{r!(n-r)!}$
