Can someone me with my algebra 2 work? its problems 23-28 all.

23) x^2 * 8

24) x^3 - 15

25) (x/4) + 5

26) 4 less than the product of 8 and a number is 16

27) The sum of a number and 3 divided by 4 is 5

28) 3 less than 4 times a number squared is 13

23)

product: means multiply

square: means ()²

8n²

24)

less: means subtract

than: means switch the order

cube: means ()³

n³ - 15

25)

more: means add

than: means switch the order

quotient: means divide

n/4 + 5

26)

8x - 4 = 16

four less than the product of eight and a number is sixteen

27)

(x + 3)/4 = 5

the quotient of three more than a number and four is five

28)

4y² - 3 = 13

three less than the product of the square of a number and four is thirteen

answer: ratio of volume of cone (with 3 times the height and equal diameter) to volume of cylinder is 2 to 1. the value of π is not used.

step-by-step explanation:

radius is diameter/2 = 4.

area of circle is π r^2.

volume of cylinder is height × area of base = hπr^2 = 3(4^2) π = 48π cubic inches.

not knowing the formula for volume of cone, i calculate it using calculus (which is for calculating things).

volume of cone is integral 0 to h area(y) dy. area(y) is π r(y)^2. r(y) runs r to zero as y runs zero to h, r(0) = r, r(h) = 0.

r(y) = r - r/h y

area(y) = π (r - r/h y)^2 = π (r^2 - 2r^2y/h + r^2y^2/h^2) = π r^2(1-2y/h+y^2/h^2)

antiderivative area(y) = π r^2 (y-y^2/h+y^3/(3h^2))

integral 0 to h = π r^2(h-h^2/h+h^3/(3h^2) - (0)) = π r^2(h - h + h/3) = π r^2(h/3) = π/3 r^2 h

volume of this cone is π/3(4^2)18 cubic inches.

= 6 16 π = 96π cubic inches.

cone has twice the volume, 96/48.

cone height is 6 times the cylinder.

ratio of volume formula: π r^2 cancels.

cone over cylinder ratio is 6h/3 to h, 2 to 1.
