Ahovercraft takes off from a platform. its height (in meters), xxx seconds after takeoff, is modeled by: h(x)=-2x^2+20x+48h(x)=−2x 2 +20x+48h, left parenthesis, x, right parenthesis, equals, minus, 2, x, start superscript, 2, end superscript, plus, 20, x, plus, 48 what is the maximum height that the hovercraft will reach?

the maximum height is the y-value of the vertex.

h(x) = -2x² + 20x + 48

       a=-2, b=20, c=48

h(5) = -2(5)² + 20(5) + 48

      =  -50   +  100   + 48

      =          50         + 48

      =                98

98 meters

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

answer:

your answer is: c. 196 7/8 in^3.
