Answer: b and d

Step-by-step explanation:

Since the roots are x=2 and x=6, we can write the equation as

$f(x)=a(x-2)(x-6)$

Substituting in the coordinates of the vertex,

$-4=a(4-2)(4-6)\\\\-4=-4a\\\\a=1$

So, the equation is $f(x)=(x-2)(x-6)$

On expanding, we get $f(x)=x^2 - 8x+12$

What is the mean of 65 125 90 and 100

WITCHER [35]

To do the mean of the numbers, you have to add them all together and divide them by the number of numbers:

65 + 125 + 90 + 100 = 380

There are 4 numbers, so you have to do

380 ÷ 4 = 95

The mean of those numbers is 95

Use the shell method to write and evaluate the definite integral that represents the volume of the solid generated by revolving

Pachacha [2.7K]

Solution :

$y=x^{3/2}, \ \ y =8, \ \ x=0$

$v=2 \pi \int_0^4 x (8-x^{3/2}) \ dx$

$$= 2\pi \left(\frac{8x^2}{2}-\frac{x^{7/2}}{7/2}\ \left|_0^4$

$=2\pi \left( 4x^2-\frac{2}{7}x^{7/2}\ |_0^4$

$=2\pi \left( 64-\frac{2}{7} \times 32 \times 4 \right)$

$=2\pi \left(1-\frac{4}{7} \right) 64$

$=128 \pi \times \frac{3}{7}$

$=\frac{384 \pi}{7}$
