Answers

Answer 1

Answer: $V=\pi r^2H\n\nH=4r\n\nthen:\n\nV(r)=\pi r^2(4r)=4\pi r^3$

Well, if you simplify both sides of the ratio, you get
24:3
which, in its simplified version, is
8:1

If x represents a number, then write an expression for a number that is three more than the number.

Answers

Answer: $x+3$

Step-by-step explanation: Since x is a quantity that we are unsure about, in order to represent it as an expression where we are adding 3 more to it, you would write it as $x+3$ .

That's it!

If f(x) = 3X + 10 and g(x) = 2x – 4, find (f- g)(x).

Answers

So (f-g)(x) is f(x)-g(x) so you have

(3x+10)-(2x-4)

Distribute the negative in to the 2x-4 to get

3x+10-2x+4

Then combing like terms you have

3x-2x+10+4

And then that gives you

x+14

So (f-g)(x)=x+14

A car fits onto a golden rectangle with a length of 12 ft. What is the car's width? Write your answer in simplified radical form and rounded to the nearest tenth of a foot.

Answers

basically, it is when legnth is $(1+ √(5) )/(2)$ the width

legnth=12
legnth= $(1+ √(5) )/(2)$ times width

12= $(1+ √(5) )/(2)$ times width
multiply both sides by 2
24= $1+ √(5)$ times width
subtract 1
23=√5 times width
divide both sides by √5
23/(√5)=width
multiply by (√5)/(√5) to rationalize denomenator
$(23 √(5) )/(5)$ =width

aprox 10.28 so 10.3 ft

w= $(23 √(5) )/(5)$ ft or aprox 10.3ft
