ty C:-0.05% of n is 15
0.0005*n = 15
n = 15/0.0005
8% of n is 0.08*n = 0.08*(15/0.0005) = 2400-answer is 2400. because .05% of n is 15. .05% x 20 = 1% so.. 15ft x 20 = 300ft if thats th
Need help answering these questions, please show working.
Solve the equation 3x^2 – 14x = 5
Write as the logarithm of a single number: 3 log 2 – log 4
Thankyou.-1) Solve the equation 3x^2 – 14x = 5
Profit-demand function
P(x) = -(x^2)/20 + 10x - 300
Demand-price function
f(p) = 40 - 20p
Tell me if the question requires more details because I dont actually understand it-x = 40 - 20*p
P(x) =
N = 8x +3y + 2n, solve for n. Somehow I need to get:
n = (N - 8x - 3y) / 2
I have the answer in the back of my book but I dont understand how to get it, and I need to because my teacher grades hard
I was wondering how you would show your working out when solving:
X^6=64
Thanks-x^6=64
(x^3)^2 = 64
x^3 = ±8
x = ±2-Seems odd that people would miss an obvious second solution. If you want to show th
can anyone give me answer with step by step method?
1. Find d^2y/dx^2,
y^4 + x + sin(y) = 7
dy/dx =1/(-4*y^3-cos(y))
i tried several ways and didnt get it right, these answers i tried and wrong..

Find f (x) using the diff. quotient for f(x) = 2x^2 + 3x
After I worked it, I got 4x + 5h, but I want confirmation. 10 points for steps.-Youre missing something.
f(x + h) = 2(x+h)² + 3(x + h) = 2x²
If 5 is added to both the numerator and the denominator of a fraction, the result is equivalent to 3/4. If 3 is subtracted from both the numerator and the denominator of the original fraction, the new
The slope is -7. The number before x is the slope whenever an equation is in slope-intercept form.-the formula is mx+b=yso woudnt the slope be -7 because m is equal to the slope.

I looked into wikipedia for derivation and I was shocked that it gives you only the formula, but not derivation. And then I cam across http://www.exposix.com/members/answers/A… , which has the derivat
Tom decides to sell flowers and vegetables from his gate so he makes two rectangular gardens.
The flower garden in 3m longer than it is wide. The length of the vegetable garden is 4m more than double
Well the only direct way I know of would require writing down the recursion relation, then, solving it...which will likely not make sense to you (unless you are familiar with differential equations or
xy*2 - 4x*3
The *2 means squared and the *3 means cubed.The equation was to be answered by factorization- difference of two squares i.e.x*2 - 16=(x+4) (x-4)
Thanks-first, take out the x

Did you know Google will give you conversion factors?Type 300 ft to m and it will give you 91.44 m
If you just want the conversion factor, type 1 ft to m-1 meter = 3.28084 ft. (rounded)
300 ft = (300
is 0.3535...a rational number? thanks-Yes, any repeating decimal is a rational number.
Lets convert 0.353535... to a fraction:
Let x = 0.353535...
Multiply by 100
100x = 35.353535...
Thus 99x = 35
x =
