Hello, Question reads:

Antidifferentiate this (an Inverse trigonometry question):

dx / square root of (9-3x^2)

(the "/" above means "over" as in the fraction sign)

Any pointers? thanks

7x + 12 = -16


1.2x = 2.3x - 2.2


4x + 21 = 7 (x +9)


| x - 4 | = 15


| 5x + 11 | = 9


| 13 + 2x | = 5

a small firm poduces both am and am/fm car radios. the am radios take 15h to produce and the am/fm take 20h. The number of production hours is limited to 300h per week. The plant's capacity is limited to a total of 18 radios per radios be produced per week. write a system of inequalities respresenting this situation.

Then draw a graph of the feasible region given these conditions in which x is the number of am radios and y the number of am/fm radios.

Could someone draw this graph for me i do not have the tools to do this please

I am going into 7th grade and got an algebra packet. I am almost finished, hust need help on some problems. DO NOT state the answer.

(^ means to the power of)

1. 3c^2(4c + 2) + 3c^3 - 3c^2 + 8

2. 3x (x^ + 5) + 7x^3 + 2x -4

3. (5c)(8c^6)

I appreciate ANYONE who helps, no matter how little. Thanks for looking!

I am taking a timed standardized test shortly (MCAT), it is very chemistry and physics heavy. The calculations are not difficult, but I am not allowed a calculator and I need to think very quickly. I was wondering if anyone has any tips or ways to "think" about a problem for quick mental math. I'll give a couple examples: something like
(0.30/8) or (1200/0.6) or (.9)^3 or (.30)^.5 My problem in mainly in thinking about decimal divisions and squares QUICKLY.

Need help with a few problems for my college algebra class, if you could help me by breaking them down that wud be great =)

Let f(x) = x^2 = 2x - 3
a.) f(a-1)

b.) f(-b)

State the equation of the circle in standard form having:

c.) center (1,3) passing through (5,6)

d.) Find the slope and y-intercept of 4x-3y= - 12

e.) write the equation g(x) that is the graph of f(x) = Square roote of x shifted 1 units and down 2 unit

f.) Find the equation of the line that passes through (2,3) and is (i) parallel and (ii) perpendicular to the line 2x-y=3

if you could answers any of these questions by breaking it down that would help me trememdously as im studying for a test.

what...i was doing this math packet our 7th grade math teacher-to-be gave us over the summer, and came across something we didn't even learn about in sixth.

the set of data:
3,3,6,7,8,11,13,14,21,22,24

lower quartile? upper quartile? inter-quartile?
how do you determine if there is an outlier in a set of data?

*please explain answer thuroughly, do not just give the answer. and explain in a way that a 6yh/7th grader will understand.

thanks much! ...♥
