h(t)= -8t2+40t + 5, 1.What is the initial height of the ball when it is thrown? 2.What is the maximum height of the ball? 3.How many seconds does it take before the ball reaches its maximum height? 4. After how many seconds will the ball hit the ground (approximate time rounded to the nearest tenths place)? 5.What is the height of the ball at 4 seconds? 6. When will the ball reach a height of 53 feet? 7. What is the domain of the function? 8. What is the range of the function?

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}

can i see the following ?

step-by-step explanation:

answer: the value of b is 24 + 3t / (4- t ) = b

solution:

step 1 : find the slope using the formula below with the c (t, 3) and d(4, -3)

m = y2-y1 / x2 - x1

m = -3 -3 / 4-t

m = -6/4-t

to find the value of   b use the equation given in the question

note : use any of the pair given c or d in the equation to find the value of b i will be using d ( 4, -3)

y = mx+ b

3 = (-6/4-t)(4) + b don't forget to take the lcm

b = (36 - 3 t ) / ( 4 - t )
