Ok so you need the surface area formula of a cone.

A = πrl + πr∧2

where π = 3.14 (pi)
r = half of the diameter (18/2 = 9)
l = slant hight ( 22 )
Slot this into the equation A = (3.14 [ rounded] )(9)(22) + (3.14 [ rounded] )(9)∧2 = 876.06 this is due to the rounded pi the answer is 876.5 i.e the third.

Hope this helps :D.

Answer:

I don't think any are a correct graph of the function. But here are the ordered pairs. (1,0),(0,-2),(-1,-4)

Step-by-step explanation:

Take three values for x and plug them in for your y's. For instance x values of 1,0,-1. Plug each in to find the y value. 2(1) - 2 =y so (1,0)

Please help me with this math problem

Scilla [17]

Answer:

see below

Step-by-step explanation:

5x - 6y = 21

Let x = 0 and solve for y to find the y intercept

-6y = 21

Divide by -6

y = 21/-6 = -7/2

The y intercept is (0,-7/2)

5x - 6y = 21

Let y = 0 and solve for x to find the x intercept

5x = 21

Divide by 5

y = 21/5 = 21/5

The x intercept is (21/5,0)

Answer:

$4x^2-8x+20$

Step-by-step explanation:

$\frac{8x^3+4x^2+100}{2x+5}$
$\frac{8x^3+20x^2-16x^2+100}{2x+5}$
$\frac{4x^2(2x+5)-4(4x^2-25)}{2x+5}$
$\frac{4x^2(2x+5)-4(2x-5)(2x+5)}{2x+5}$
$\frac{(2x+5)(4x^2-4(2x-5))}{2x+5}$
$4x^2-4(2x-5)$
$4x^2-8x+20$

Let f(x)=2x^2+x-3 and g(x)=x-1. Perform the indicated operation, then find the domain.

Dominik [7]

Multiplying the two functions together using the Distributive Property, we get (2x²+x-3)*(x-1)=2x³+x²-3x-2x²-x+3= 2x³-x²-4x+3. In addition, since any value x can be plugged into 2x³-x²-4x+3, A is your answer!
