Answer: r=4 inch

              H=8 inch

Step-by-step explanation:

V=402 inch³

H=2r

V=Hr²π

402=2r*r²π

402=2r³π

402/2π=r³

64=r³

r=4

H=2*4=8

Solve for w. 5w + 9z = 2z + 3w w = w equals negative StartFraction 7 Over 2 EndFraction z.Z w = w equals negative StartFraction
TEA [102]

Answer:

w = -7z/2

Step-by-step explanation:

We need to solve for w in terms of z.

The equation given is:

5w + 9z = 2z + 3w

Collect like terms:

5w - 3w = 2z - 9z

2w = -7z

w = -7z/2

Please please help!!! I really need help on this quarion and I keep getting it wrong :(
Marta_Voda [28]

Answer:

f(x)=x^2+4\\g(x)=4x

(f+g)(x)=x^2+4+4x\\(f+g)(x)=x^2+4x+4

------------------------------------------------------------------

(f-g)(x)=x^2+4-(4x)\\(f-g)(x)=x^2+4-4x\\(f-g)(x)=x^2-4x+4\\

-----------------------------------------------------------------

(f*g)(x)=(x^2+4)(4x)\\(f*g)(x)=4x^3+16x

-----------------------------------------------------------------

(\frac{f}{g})(x)= \frac{x^2+4}{4x} \\

A boat drops an anchor 75 feet to the bottom of a lake. A sunken treasure chest lies at the bottom of the lake, 40 feet away fro
Reil [10]
Given
Height (length) of the anchor dropped from the boat = 75 feet
Distance of the treasure from the anchor = 40 feet

Solution
The dropped at the bottom makes an angle of 90 degree . Therefore making an right triangle with the chest and boat

By Pythagoras theorem
AC^2 = AB^2 + BC^2

(AC = distance of the treasure from the boat
AB = height of the anchor dropped from the boat
BC = the distance of treasure from the anchor)

AC^2 = 75^2 + 40^2
AC^2 = 5325 +1600
AC^2 = 6925
AC = 25 * (under root 11)

Therefore they have cover a distance of 25 * (under root 11)
