Please help me with these problems!
a). 100
b). 256
c). 1001
d). 2*3*5*7*11*13
e). 10!
f). 20!-Use prime factorizations along with φ(p^n) = p^n - p^(n-1).
a) φ(100) = φ(2^2 * 5^2) = φ(2^2) * φ(5^2) =
Find the equation of the tangent line to the curve at the given point: y = (x - 1) / (x - 2) , coordinates (3, 2).
Im trying so hard to figure out the derivative of the function, but I just cant do i
Ive tried this problem several times, following a help guide but still cant seem to get it right. Help please?
Find the distance between the skew lines with the given parametric equations.
x = 3 + t
please i need help-Think of it this way - all positive divisors come in PAIRS. So the only way for there to be an odd number of divisors is if one of those pairs is (x,x). That is - the number must be
Hey guys Im having a hard time with this problem on my homework which is done online. I got the first answer correct but everything else Im confused about. All your help will be appreciated. :)

1.) Evaluate the line integral, where C is the given curve. (Round your answer to one decimal place.)∫c [xy^2] ds, C is the right half of the circle x2 + y2 = 16 oriented counterclockwise
2.) Evalua
A rock star who works part time as chemist, invests a total of $12,000 in 2 accounts. One account earns 4% interest per year; the other account earns 7% per year. If the total interest she earns in on
16x^2+9y^2-36y=108
Please show how you complete the square and what kind of graph this is please. been trying this for quite a while. Cant get a fix on it.-16x^2+9(y-2)^2 =108+9*4 = 144
x^2/9 + (y-2)
I have a triangle with an angle of 60 and opposite side of 4.
I am trying to find the hypotaneuse so I use tangent.
Sin= opposite divided by hypotaneuse.
Sin60=4/H
H=4xSin60
H=3.46
I know the answer
the operation && is defined for all values of x and y by the equation x&&y = x^2 + y^1/3. What is the value of -4&&x if x = 5&&8
the answer is 19. But I dont know how they got it, I keep getting -6.8-
show work put in standard form first-not sure wat you mean but ima guess and TRY to help . Sorry if this isnt it . x + 2y = 6-x-x2y=6-x2/2 6/2y = 3 - x
3 is your y intercept , -1 is your slpe .
suppose that the dollar cost of producing x appliances is c(x)=1000+90x-0.2x2
a) find the average cost per appliance of producing the first 110 appliances.
b)find the marginal cost when 110 appliances
What is the main difference between the graphs of y= 4-x^2 and 2y= 4-x^2?
Im confused with wether I would need to move the 2 over to the right side, and if i need to multiple that number by 4?
