1. Find the indefinite integral of ∫ cos5x ∘ e^sin5x dx

2. Evaluate the definite integral of ∫ 1 to 7 (e^3√x / √x) dx

3. Find dy/dx of y = e^2x5

I found three more questions i did not understand. I'd appreciate the help. Thank you

1. Find dy/dx at point (3,1), for the equation x = y^3 - 5y^2 +7

2. Find the slope intercept equation of the line tangent to the graph of y = e^x when x = ln2

3. Solve the following equation for x.

lnx^-7 = 2

If someone can help I would really appreciate it.

1.

y= ln( 1+e^x / 1-e^x)

2.

y= ln(e^x + e^-x / 2)

3.

y= xe^x - e^x

4.

f(x) = e^3lnx

Find the Second Derivative Functions. Please Help!!?

1.

f(x) = 2(x² - 1)^3

2.

f(x) = 1 / x-2

3.

f(x) = sinx²

4.

f(x) =sec²πx

Hope you could help. I would appreciate it! Thanks

1. Find the x-values (if any) at which f is not continuous. Which of the discontinuities are removable?

f(x) =

{ -2x + 3, x < 1

{ x^2 , x ≥ 1

2. Is the function continuous on the entire real line?

f(x)=

|x^2 + 4x| (x+2) / x + 4

1.)

solve algebraically.

log[8] 3x - log[8] (10 + √x) =2

2.) fin arc length of a circle with a radius of 9 inches and a central arc of 7pi/ 4

3.)

solve for x, y, and z.

x + y + z = 1

x - 6y - z = 14

-7y + 2z = 29

4.)

Write the form of the partial fraction decomposition of rational expression

4 / x^2 + 10x

You are working ALONE and are schedule to leave at 5:00 p.m.. The worker that is scheduled to replace you at 5:00 p.m. has not called nor arrived. What do you do?

Please help me answer this problem. I know its pretty simple, but i cant figure it out.

Im 15 going on 16 in November and for the past 4 and a half years i've been getting my period. sadly it hasn't been regular. It's usually 2 weeks to a month late. Im afraid it'll affect me in the future, having children and sexually, my doctor talked about putting me on birth control but never took action in doing so.

What i want to know is;

*Could this be some type of hormone imbalance?

*If so, Could it affect my sex life (Self-lubricating...in other words, BEING DRY)?

*Is there a way to fix my problem with and/or without medication?

I would appreciate if you could help me out

You see im 15 and i've been having my period since i was 11. Since i've had it, its been abnormal. When i lost my virginity ( at 14 ) my period started to come on time. Now its back to being abnormal. The last time i had sex, Jan 28, i was a month and a half late on my period, and thought i could've been pregnant. I wasn't obviously! But I just want to know what are the possible reasons for my abnormal period.

Could this be a sign that later on in the future ill be unable to have children?

Ive been with my boyfriend for about 6months..our sexual relationship is great but we seem to just do normal things. I been thinking about trying oral with him but im not sure how to let him know! Do I just come out and say "Let me give you a BJ"??

If you could help i would really happy!

xoxo
