For zeroes of r1,r2,r3, the factors of the function, f(x) are
(x-r1)(x-r2)(x-r3)

zeroes of -3,-5,2
(x-(-3))(x-(-5))(x-2)=
(x+3)(x+5)(x-2)

f(x)=(x+3)(x+5)(x-2)
expanded
f(x)=x³+6x²-x-30

Find the volume of the ellipsoid x2+y2+4z2=100x2+y2+4z2=100.
kondor19780726 [428]
Given the ellipsoid x^2+y^2+4z^2=100

For the radius in the x-dirextion, y = z = 0, and we have

x^2=100 \\  \\ \Rightarrow x=\pm10

For the radius in the y-dirextion, x = z = 0, and we have

y^2=100 \\  \\ \Rightarrow y=\pm10

For the radius in the z-dirextion, x = y = 0, and we have

4z^2=100 \\  \\ \Rightarrow z^2=25 \\ \\ \Rightarrow z=\pm5

Thus, the radius of the ellipsoid is given by

Volume=4\pi r^3=4\pi\times10\times10\times5=500\pi

HELLPPP DUE TODAY AT 4
Natalka [10]

Answer:

2 and 2/3 for the first question

-1/8 for the second one

-1/5 for the third one

ive never done this type of question or maybe it was too long ago for me to remember but out of this answer choices i would guess that its the last one

this is 3

Step-by-step explanation:

you add the numerators which is the top number in order to get 2 and 2/3rds

you subtract 5 from 4 to get -1/8

same situation as the last one, subtract 15 from 11 to make it a negative 4/20 and then simplify that by dividing it by four to get 1/5th

this one i dont understand or remember how to do very well but if i had to guess its the last answer choice

this one you add 3/4 plus 1/4 in order to get 4/4 or rather 1, so basically its asking what 1+1+1 is which is 3
