I do.

Oh my that cake is beautiful!!!!

And Mystical

Everyone is welcome to have a slice!!!!

Thanks SO much!!

There Cphill you can have a piece!!

Distance /Time   = Rate

1200m / 0.5s     =  2400m/s

These occur where the cosine  = 0

So.......at    pi/2  and  3pi/2

Here's the graph that confirms this : https://www.desmos.com/calculator/5ez2c90mgb

This is the equation of a line.....it has infinite "solutions"

Here's the gragh :

Just divide:

48 / (3 1/5) =48 / (16/5) =48  x 5/16 =240/16=15 pieces that can be cut.

Using the identity that

1 + tan^2    = sec^2     ..so....ubtract 1 from both sides

tan^2   =  sec^2 - 1

tan^2  =  (-5/4)^2  - 1

tan^2  =   25/16  - 1

tan^2   =   9/16         since  the tangent is positive in the 3rd quadrant....take the positive root

tan  = √ [9/16]  =    3/4

Happy B'Day, MJ........here's a cake.....

You'd better hurry up and eat a piece before I get to it......!!!!!

x * (4x + 7) =480, solve for x

Solve for x:
x (4 x + 7) = 480

Expand out terms of the left hand side:
4 x^2 + 7 x = 480

Divide both sides by 4:
x^2 + (7 x)/4 = 120

Add 49/64 to both sides:
x^2 + (7 x)/4 + 49/64 = 7729/64

Write the left hand side as a square:
(x + 7/8)^2 = 7729/64

Take the square root of both sides:
x + 7/8 = sqrt(7729)/8 or x + 7/8 = -sqrt(7729)/8

Subtract 7/8 from both sides:
x = sqrt(7729)/8 - 7/8 or x + 7/8 = -sqrt(7729)/8

Subtract 7/8 from both sides:
Answer: | x = sqrt(7729)/8 - 7/8 =~10.11 inches.

i would hope not 

yes xd

oooh fish I see

Distance between cities = (5.7 / 4) * 250   = 356.25 miles = 356.3 miles (rounded)

250 / 4 =62.50 miles per inch.

5.7 x 62.50 =356.25 miles - the actual between the two cities.

Wait what?

Awww Thank you sooo much wgunningham!!!! 
I really appreciate it!!!

.65 * 450  = $292.50

Square footage to be covered   = 18 * 9  = 162 ft^2  (A)

Area that  each tile covers = 1.5 ft^2   (B)

So.....tiles needed  = A /B  =     162/ 1.5  = 108

39/4 = 9.75

or

39/4 = 9 r3

It would be 9.75

Thanks so much everybody!!

happy early b-day MysticalJaycat!!!

5x + 4 < 29     subtract 4 from both sides

5x < 25           divide both sides by 5

x < 5

So   {3,4}   is correct

As n tends to infinity (n + 1) tends first to n, and (2n + 1) tends to 2n and (2n + 2) tends to 2n, so (n+1)^2/(2n+2)(2n+1) tends to n^2/(2n)^2 = 1/4.
