An object dropped from a height of 170 feet will fall according to the equation h ( t ) = 170 − 16 t 2 , where t is measured in seconds, and h(t) is measured in feet. What is the height of the object after 1.1 seconds? feet.

How long will it take for the object to hit the ground? seconds Give your answers as decimal values, accurate to 2 decimal places

step-by-step explanation:

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

it is x equals 3   plese mark me really need it

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
