Answer:

4 is the correct answer

Step-by-step explanation:

y=(x+5)(x-3)

so x intercept means the value of x when y is zero

0=(x+5)(x-3)

x+5=0 so x=-5

x-3=0 so x=3

What is the volume of a cone with a diameter of 30 feet and a hight of 60 feet​
ivolga24 [154]

Answer:

4500\pi ft^{3}or 4712.39ft^{3}

What we need to know: The formula for the volume of a cone is: V=\pi r^{2} \frac{h}{3}

So we are solving for V

Step-by-step explanation:

1) Radius is half of diameter r=30/2 thus, your radius is 15

2) you then have all your variables so you can start plugging values into your equation:

r=15 h=60

V=\pi 15^{2} \frac{60}{3} \\V=\pi (225)*(20)\\V=\pi(4500) \\V= 4500\pi

This would be your exact answer but if you are solving for a rounded answer it would be

V~4712.39ft^{3}

Multiply and simplify. 2x4yx⋅6xy2z3
OLEGan [10]

Answer:

The given expression 2x^4yx \times 6xy^2z^3   on multiplying  is 12x^6y^3z^3

Step-by-step explanation:

Consider the given two expressions 2x^4yx and 6xy^2z^3

We have multiply both expressions,

2x^4yx \times 6xy^2z^3

To multiply two terms first multiply constant numbers that is 6 × 2 = 12

For x , y and z apply property of exponent,

x^a\cdot x^b=x^{a+b}

Then power of x together will be,

x^4\cdot x\cdot x=x^{4+1+1}=x^6

Similarly for y powers,

y \cdot y^2=y^{1+2}=y^3

Since first term do not have any expression for z so it will remain same.

Thus, the given expression  on multiplying become,

2x^4yx \times 6xy^2z^3 is 12x^6y^3z^3
