PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!-31 = 4x^3 + 1

+2 under the radical (h) means the graph moves two units to the left, while +4 outside the graph (k) means the graph moves up two units. Don’t forget for h, a positive number means move left, negative means right.

an elevator traveled from the 10th floor to the 2nd floor in 6 seconds. what was the rate of the elevator in floors per second

ycow [4]

Since it went 8 floors in 6 seconds you divide. 8/6 is 1.333 or 1 1/3 floors per second. Hope this helps.

LAST QUESTION! Please help! Please

The correct answer is: [C]: " 37, 680 mm³ " .
________________________________________________________

Explanation:
________________________________________________________

The formula for the volume, "V" , of a cylinder is:

→ V = $\pi$ * r² * h ;

→ in which "r = length of radius" ; "h = height" ; ________________________________________________________

{Note that the formula for the volume, "V" , of a cylinder is:

→ " Base area * height " .
________________________________________________________

→ Specifically, for a cylinder, the "Base area" is the area of a "circle", because the base is a circle;

→ and the formula for the "area of a circle = [tex] \pi [/tex] * r² " ;

  → in which "r = length of the radius" .

As such, the formula for the volume, "V" , of a cylinder is:
______________________________________________________
→ Volume = (Base area) * (height) ;

= ( $\pi$ r² ) * h ;
______________________________________________________

→ V = $\pi$ r² h ;

in which: "V = volume  {in "cubic units" ; or, write as " units³ " } ;

"r = radius length" ;

"h = height" ;
_____________________________________________________
→ Now, we shall solve for the volume, "V", of the given cylinder in this question/problem:
_____________________________________________________

→ V = $\pi$ r² h ;

in which: "r = radius = ? " ;

  → To find "r" ; We are given the diameter, "d = 40 mm" ;

→ Note that: "r = d/2 = (40 mm) / 2 = 20 mm " ;

{i.e., "the radius is half of the diameter".}.

  → " r = 20 mm " ;

  → " h = height = 30 mm " {given in figure) ;

  → For $\pi$ ; let us use " 3.14 " — which is a commonly used approximation.

→ For this question/problem, none of the answer choices are given "in terms of $\pi$ " ;
→ so we shall use this "numerical value" as an "approximation" ;
_______________________________________________________

Now, let us plug in our known values into the formula;
and calculate to find the volume, "V", of our given cylinder; as follows:
_______________________________________________________

  → V = $\pi$ r² h ;

= (3.14) * (20 mm)² * (30 mm) ;

= (3.14) * (20)² * (mm)² * (30 mm) ;

= (3.14) * (20)² * (30) * (mm³) ;

= (3.14) * (400) * (30) * (mm³) ;

= 37, 680 mm³
__________________________________________________

The volume is: " 37, 680 mm³ " ;

→ which is: Answer choice [C]: " 37, 680 mm³ " .
___________________________________________________
Hope this answer and explanation—albeit lengthy—is of some help to you.
Best wishes!
