What is the second derivative for the function y=e^(6-x^2) ? Please show workings.
the equation for the general form of a circle is 2x2 +8x +2y2 -y -2 . I have done this problem countless times and cannot for the life of me get the radius. I have found h = -2 and k = 1/8...
a lighthouse is 100 meters from a straight shoreline. the light turns at a rate of 10 revolution per minute (20π radians/minute), and shines a moving spot of light along the shore. How fast is the...
A ball is thrown in the air. The height of the ball is given by the equation h(t)=-16t^2+30t, where t is the time in seconds. How long will it take for the ball to hit the ground,...
A woman invests a total of $20,000 in two accoutns, one paying 5% and the other paying 8% simple interest per year. Her annual interest is $1180. How much did she invest at each rate?...
Log x + log (x+15) = 2 How is this solved?
A) 7x-5y+4z-9=0 -x+3y+5z-2=0 5x+y+14z-20=0 b) 7x-5y+4z-9=0 -5x+4y+z-3=0 x+2y-z+1=0 c)...
The variable x is confusing me~
Supply: p =5q2 Demand: p = 4800 - q2/3 I figured out price is p= 4500 and q = 30 (at equilibrium) now how do you solve for the surplus of both. I know it's a type of...
Find the area of the region bounded by y=-x^3+3, y=x, x=-1 and x=1
I completed this problem I just want to check my final answer. I got 27/6 and simplified it to 9/2 as my final answer
Evaluate the definite from -π/4 to π/4 ∫sin2xdx -π/4 to π/4= -pi/4 and pi/4
Supply: p=5q2 Demand: p= 4800 -92/3 I assume you have to set these equal to each other to find consumer and producer surplus but I'm not sure how to solve. ...
an island lies 4 miles offshore from a straight beach. down the beach 5 miles from the point of the beach neareset the island there is a store. aman visits the store regularly, using a rowboat to...
find the particular solution of the differential equation f"(x)=6(x-1) whose graph passes through the point (2,1) and is tangent to the line 3x-y-=0 at that point
Find the average value of the function f(x)=x^3 over the interval [0,2] and find the value(s) of x at which the function assumes the average values
The pulley is 5ft above the height at which the rope is attached to the boat. If R(t) represents the length of the rope between the boat and the pulley, determine the value of R'(t) at the moment...
I can't figure out how to differentiate this function. Any help would be appreciated. y=ln(x9(sin(x))2) Find y'(x)=
use sigma notation to write the sum 9/(i+1)+9/(i+2)+9/(i+3)+....+9/(i+14)
A particle is moving with velocity v(t) = t^2 – 9t + 18 with distance, s measured in meters, left or right of zero, and t measured in seconds, with t between 0 and 8 seconds inclusive. The position...
