13^2-5^2 = 144
c = 12x
30x = 75
x=2.5
a = 12.5
b = 32.5
c = 30.0-The two shorter sides of any triangle must add up to a number that is longer than the third, longest side.A right triangle usually uses
Estimate how many 9 inch diameter pots can fit on 12.75 ft wide by 75 ft long bench-9 = 3/4 foot. (.75 ft)
So, you can place 12.75 / .75 = 17 pots along the 12.75 ft length and 100 pots along the 75
(1/2)^t/0.18-okay so
(1/2) is the same as 0.5
0.5^t / 0.18=(multiple both sides by 0.18)
0.09^t = 0.18
divide both sidesby 0.09
t=2-Im sure it is something like doing the ( )s first the divide .
a.) Convert (BEAD) base 16 to base 10
b.) Convert (17837) base 10 into hexadecimal/base 16-There should be examples in your book.For the first one, you take B*16^3 + E*16^2 + A*16 + D, remembering tha
I have a huge test tomorrow, but I still dont know how to solve 3 system of equations with 3 variables, somehow I always end up getting fractions. Can you please help me? Thank you.

Calculus help! If f(x)=2x^3 - 5x + 5....?
show that there is at least one value of c for which f(x) equals π.-f(2)=2*8-10+5=11
f(1)=2.
f is continuous and 2-x = 5/(1/2 (-540+108 pi+i sqrt(-183600+116
I need the solution step by step so i can understand it correctly please.. thank you guys-Do you know how to calculate Gaussian integrals?
let u = x^{1/2}, then2 du = x^{-1/2} dx, so your integral is
8. If the demand equation is given byQD= 10 – 2P, write the corresponding marginal revenue (MR) equation.
a. MR = 10 – 4P
b. MR = 5 – 2Q
c. MR = 5 – Q
d. MR = 10 – Q
I know the answer is C ( I have
The kid on the corner is running a game in which a fair coin is tossed twice. If exactly two tails occur, the player wins $5. If exactly one head occurs, the player wins $1. Otherwise the player gets
I know this is very easy but I completely forgot and I really need to know. :P
b times what equals b^3
the ^ means the power of 3-(b)(b^2) = b^3
ANSWER: b^2 (read: b squared).
*When multiplying like
what is the x and y intercept for a line passing through the points (-1,5) and (2,-4). I found the slope if that counts, its -3. But I dont know where to go from there, im having a brain fart.-You fou
if x^2 + y ^2 = 30 and (x + y)^2 = 56. Find (x - y)^2.
The answer is 4 but I dont know how they got it-(x-y)^2 = (x+y)^2 - 4xy= 56 -4xy....................(i)
Also(x+y)^2 = x^2+y^2 +2xy56=30 +2xy2xy =
Write a formula that estimates the change in the volume v=(4/3)(pi)(r^3) of a sphere when the radius changes from r to r+dr. (Please show work).
dV=???dr
thanks-just take the derivative.
dv/dr =
(cos(2x))^2-(sin(2x))^2+sin(2x)=0
Im not even sure where to start. I tried factoring our sin2x, but then I couldnt figure out what to do with cos^2 -sin2x-sin^2 + cos^2 = 1 or cos^2 = 1 - sin^2. Subst
