Hi could you just share final answers thank you

The marginal prot in dollars on Brie cheese sold at a cheese store is given by P'(x) = x(80x2 + 60x} , where x is the amount of cheese sold, in hundreds of pounds. The "prot" is $?0 when no cheese is sold. a. Find the prot function. h. Find the prot from selling 300 pounds of Erie cheese. '7.1.44} . Question Helpv ' a The slope of the tangent line to a curve is given by f'(x} : 4x2 + 9x 4. If the point (0,4) is on 1he curve, nd an equation of the curve. f{x) = Find the cost function if the marginal cost function is given by (3'00 2 x2 "3 + 8 and 2? units mew-141. 09:} = D Use substitution to find the indefinite integral. 2 dm (2m + 1) Describe the most appropriate substitution case and the values of u and du. Select the correct choice below and fill in the answer boxes within your choice. O A. Substitute u for the quantity in the denominator. Let u = So that du = ( ) dm. O B. Substitute u for the quantity under a root or raised to a power. Let u = so that du = () dm. O C. Substitute u for the exponent on e. Let u = , so that du = ( ) dm.Use substitution to find the indefinite integral. 8x + 5 (4x2 + 5x) 3 OX Describe the most appropriate substitution case and the values of u and du. Select the correct choice below and fill in the answer boxes within your choice. O A. Substitute u for the entire quantity in the denominator. Let u = , so that du = (dx O B. Substitute u for the quantity raised to an integer power. Let u = so that du = ( ) dx. O C. Substitute u for the quantity in the numerator. Let u = , so that du = ( ) dx
