This seems like an easy question yet I am not able to comprhend. Question: Inher latest game, Mary bowled 199 and raised her average to 179 from 178. To raise her average to 180 with the next game, what must she bowl? Her average was 178. The average is the sum of the scores ...

Great! I understand now that C0=f(a) c1=f'(a) c2=f"(a)/2 Now, If I am to find the parabolization of the equation x^2-x at x=2, then c0=x^2-x=2^2-2=2 c1=2x-1=2(2)-1=3 c2=2/2=1 So, the equation (taken from c0+c1(x-a)+c2(x-a)^2) is >> 2+3(x-2)+1(x-2)^2?? Is this correct? ...

Having trouble getting the correct solution. The integral of “x squared” in the numerator and “x squared plus x minus 6” in the denominator. S X2 / (X2 + x – 6) dx Thanks! That's a messy one. According to my table of integrals. The answer is -x/6 -(1/72)loge(x^2 +x -6) + S dx...

AP Calc-easy ?
Given: f(x)= x^3 + x^2 - 2x over the closed interval [0,2] Write the equation of the tangent line to f(x) passing through point A(-1,-2). *At first glance I knew how to do it, but f(-1) does not equal -2...so do I add a constant onto f(x) to make f(-1) = -2 or what? thanks

The remainder is a fraction (remainder/divisor). Why dont you use a calculator...for instance, 31/7 is 4 r 3, but it is easy enought to just put 31 divide by 7 in the calc. I have to solve a proportion, and the answer I come up with has a remainder. I know I need to make the ...

Personally, I like gaussian reduction as a choice method, becausing my TI83 does it very quickly and accurately. But for your methods, graphing on a graphing calc is fast. In school, often variables are assigned whole number values, which make elimination easy, but in real ...

Easy (yet confusing) Algebra
These problems are pretty easy, but confusing (as stated in the subject line). |2x+5|-x=10 |3x+4|-2x=11 I know there are supposed to be two answers for each problem, for the first problem I got 5 and for the second problem I got 7. I can't figure out the other answers for the ...

Verify that the function satisfies the three hypotheses of Rolle's Theorem on the given interval. Then find all numbers c that satisfy the conclusion of Rolle's Theorem. f(x)= x sqrt(x+21) , [-21,0] If there is more than one solution separate your answers with commas. c = Do ...

Find the exact total of the areas bounded by the following functions: f(x) = sinx g(x) = cosx x = 0 x = 2pi I set my calculator to graph on the x-axis as a 2pi scale. The two functions appear to cross three times between x = 0 and 2pi. (including 2pi) Now, from top to bottom, ...

Can someone help me find the exact value of 4csc(3pi/4)-cot(-pi/4)? Thanks! cotx =1/tanx cscx = 1/sinx If you find it easier to conceptualize in degrees, realize that pi/4 radians is 45º and 3pi/4 is then 135º If you know the CAST rule, it is easy to see that -pi/4 is in the ...

I'm stuck on a pre-calc problem. I need to find y as a function of x, where the constant c is a positive number for In(y-1)+In(y+1)= -x+c express your question as ln[(y-1)(y+1)] = -x+c change that to exponential form e^(-x+c) = (y-1)(y+1) e^(-x+c) = y^2 - 1 y^2 = e^(-x+c) + 1 ...

I assume you wont have a double side on the adjoining sides. If you do this, you have 102 m of perimeter, to do 3 widths (two ends and center fence), and 2 lengths. Area= lw P= 3w+2L or L= 1/2(102-3w) Area= 1/2 w(102-3w) This is easy in calc, but I assume you are not there ...
