Answer:

50.24 cm³

Step-by-step explanation:

The volume (V) of a cone is calculated as

V = $\frac{1}{3}$ πr²h

where r is the radius of the base and h the height

Here r = 4 and h = 3, thus

V = $\frac{1}{3}$ × 3.14 × 4² × 3

= $\frac{1}{3}$ × 3.14 × 16 × 3 = 16 × 3.14 = 50.24 cm³

Answer:

(-3,-1.5)

Step-by-step explanation:

The two points are: (-2,1) & (-4,-4)

$x = \frac{ - 2 - 4}{2} = - 3 \\ \\ y = \frac{1 - 4}{2 } = - \frac{3}{2} = - 1.5$

Find the zeros of the function. 9x^2-36=0 I've gotten half way right up to 9(x^2-4)=0

Airida [17]

Answer:

x = ±2

Step-by-step explanation:

9x^2-36=0

Using the square root property

9x^2 = 36

Divide each side by 9

x^2 = 4

Take the square root of each side

sqrt(x^2) = sqrt(4)

x = ±2

QF Q6.) Find the function for a.

irakobra [83]

The function for a is (f o g) (x) = 8x^2-10.

Explanation

=========================
$f(x)=2x-4, g(x)=4x^2-3, (f o g)=f(g(x))$

I already knew that the g of x is equal to $4x^2-3$ so I substitute inside of the g of x

$g(x)=4x^2-3$ =======> $f(x)=4x^2-3$ =============> $2(4x^2-3)-4$

simplify it

$2(4x^2-3)-4$ =======> $8x^2-6-4$ =========> $8x^2-10$

$(f o g) = 8x^2-10$
