I Have Done All But The Letter C I Can Not Figure Out How To Set This Equation U
I have done all but the letter C. I can not figure out how to set this equation up.
5. (10 pts) Alan went on a diet. Alan’s weight w in pounds t weeks after the start of the diet is modeled by
w(t) = -0.004t3 + 0.18t2 – 3t + 280 for 0 £ t £ 15 weeks.
(a) What was Alan’s weight at the start of the diet?
W(0)=-0.004(0)2+0.18(0)2-3(0)+280 0 £ t £ 15 weeks W=280
(b) What was Alan’s weight 15 weeks after the start of the diet? Show work.
W(15)=-0.004(15)2+0.18(15)2-3(15)+280 0 £ t £ 15
-0.004*3375+0.18*152-3*15+280
-0.004*3375+0.18*225-3*15+280
-13.5+0.18*225-3*15+280
-13.5+40.5-3*15+280
-13.5+40.5-45-280
W=262
(c) Find and
