4. The temperature of a sample of a fluid that is being heated in a laboratory is given by h(t) = 30t − t^2 degrees Celsius, where t is measured in minutes and 0 ≤ t ≤ 5. Find the equation of the tangent line to h(t) at t = 3.

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

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:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
