The height, h, in feet of the tip of the minute hand of a wall clock as a function of time, t, in minutes can be modeled by the equation h=0.75cos(pi/30(t-15))+8. which number (from 1 to 12) is the minute hand pointing to at t = 0? a.) 3 b.) 6 c.) 9 d.) 12

Option C - 9  

Step-by-step explanation:

Given : The height, h, in feet of the tip of the minute hand of a wall clock as a function of time, t, in minutes can be modeled by the equation .

To find : Which number (from 1 to 12) is the minute hand pointing to at t = 0?

Solution :        

We have given the model of a wall clock  

Where h is the height in feet of the tip of the minute hand of a clock wall

and t is the time in minutes

We have to find when t=0 then minute hand pointing to

Substitute t=0 in the given model,

Approximately h=9

Therefore, Option C is correct.

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
