Abox is tossed upward from a cliff that is 12 meters high, at a speed of 11 meters per second. the height of the box in meters is given by h(t)=−4.9t2+11t+12 where t is seconds. what is the height of the box at 1 second?

18.1 meters

Step-by-step explanation:

h(t) = -4.9t² + 11t + 12

When t = 1:

h(1) = -4.9(1)² + 11(1) + 12

h(1) = -4.9 + 11 + 12

h(1) = 18.1

The height of the box is 18.1 meters.

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8

middle maybe?
