Pre-Calculus
I dont know why the format is like this but the symbol behind the sin25 are degrees,the letter a on the answers are root, and the fl letter on number 3 are suppose to be PIE

A photogrpaher points a camera at a windows in a nearby building forming an angle of 42 degrees with the camera platform. If the camera is 52 meters from the building , how high above the platform is the window, to the nearest hundreth of a meter. The answer is 46.82m, i would...

A ladder leans leans against a building that has a wall slanting away from the ladder at an angle of 96 degrees with the ground. If the bottom of the ladder is 23 feet from the base of the wall and it reaches a point 52 feet up the wall, how tall is the ladder to the nearest f...

Evaliuate the differnce quotient f(x+h)-f(x)/ h for f(x) = X^2 + 2x - 2 currently i have done (x+h)^2 + 2(x+h)-2 - x^2-2x - 2 / h the answer is 2x+h+2 but each time i try to work on the problem i dont get this answer... thanks in advance

Find the standard form of the equation of the circle. 3(x+2)^2 + 3(y-1)^2=18 so i used this formula r^2 = (x+h^)2 + 3(y+k)^2 i just plug in the number but what do i do with the 3's outside of the parenthesis or i have to do something else...

math(Pre-Calculus)
also for the -f(x) in the different quotient i think i also forgot to insert 3x-1 and 2x^2+3x into my equation.... anyone

math(Pre-Calculus)
i just noticed i forgot to divide by h and forgot the -f(x):ooooooo but still can anyone post the answers so i know if im doing this right or wrong

math(Pre-Calculus)
Evaluate the difference quotient F(x)= (x+h)-f(x) ----------- H A.) f(x)= 3x -1 so far i have done this f(x+h) = 3(x+h)-1 b.) f(x)=2X^2 + 3X i have done this f(x+h)= 2(x+h)+3(x+h) im not sure if my answers are right.. just need some advice if they are wrong and explain what i...

Math (Pre-Calculus)
Find an equation of the line containing the points (8,-6) and (8, -4) so far i've tried y-y1=m(x+x1) but currently cannot get the answer....T-T the answer is suppose to be x=8 plz show the work so i can study form it and do it myself the next time... thnx in advance
