Consider the vector field f(x, y,z)=(2z+5y)i+(z+5x)j+(y+2x)kf(x, y,z)=(2z+5y)i+(z+5x)j+(y+2x)k. a. find a function ff such that f=∇ff=∇f and f(0,0,0)=0f(0,0,0)=0. f(x, y,z)=f(x, y,z)= b. suppose c is any curve from (0,0,0)(0,0,0) to (1,1,,1,1). use part a. to compute the line integral ∫cf⋅dr∫cf⋅dr.

If f(x) = -5x + 1 and g(x) = x3, what is (gºf)(0)? enter the correct answer

Titus works at a hotel. part of his job is to keep the complimentary pitcher of water at least half full and always with ice. when he starts his shift, the water level shows 4 gallons, or 128 cups of water. as the shift progresses, he records the level of the water every 10 minutes. after 2 hours, he uses a regression calculator to compute an equation for the decrease in water. his equation is w –0.414t + 129.549, where t is the number of minutes and w is the level of water. according to the equation, after about how many minutes would the water level be less than or equal to 64 cups?
