The function H(t) = −16t2 + 60t + 95 shows the height H(t), in feet, of a projectile after t seconds. A second object moves in the air along a path represented by g(t) = 20 + 38.7t, where g(t) is the height, in feet, of the object from the ground at time t seconds.Part A: Create a table using integers 1 through 4 for the 2 functions. Between what 2 seconds is the solution to H(t) = g(t) located? How do you know? (6 points)

Part B: Explain what the solution from Part A means in the context of the problem. (4 points)

Answers

h(t) = -16t² + 60t + 95
g(t) = 20 + 38.7t

h(1) = -16(1²) + 60(1) + 95 = -16 + 60 + 95 = -16 + 155 = 139
h(2) = -16(2²) + 60(2) + 95 = -16(4) + 120 + 95 = -64 + 215 = 151
h(3) = -16(3²) + 60(3) + 95 = -16(9) + 180 + 95 = -144 + 275 = 131
h(4) = -16(4²) + 60(4) + 95 = -16(16) + 240 + 95 = -256 + 335 = 79

g(1) = 20 + 38.7(1) = 20 + 38.7 = 58.7
g(2) = 20 + 38.7(2) = 20 + 77.4 = 97.4
g(3) = 20 + 38.7(3) = 20 + 116.1 = 136.1
g(4) = 20 + 38.7(4) = 20 + 154.8 = 174.8

Between 2 and 3 seconds. 
The range of the 1st object is 151 to 131.
The range of the 2nd object is 97.4 to 136.1

h(t) = g(t) ⇒ 131 = 131

It means that the point where the 2 objects are equal is the point where the 1st object is falling down while the 2nd object is still going up. 

What is the value of x in the equation 4x+8y=40 when y=0.8

Answers

Substitute in 0.8 for y.

4x+8y=40 \n \n 4x + 8(0.8) = 40 \n \n 4x + 6.5 = 40 \n \n 4x = 40 - 6.4 \n \n 4x = 33.6 \n \n x = 8.4 \n \n

The final result is: x = 8.4.

you plug in the y .8 to the8 that is 6.4

them you subtract 40 by 6.4that is  33.6

then you divide that by 4is 8.4

What is pie time 4 times 10

Answers

the answer is 125.6

pi (3.14) x 4 = 12.56 

12.56 x 10 = 125.6
Not to be rude, I just have issues with improper English, but: correction: Pi.
Pi is 3.14, so multiplying it by 4 would be 12.56. Proceeding to multiply it by 10 would give you 125.6. : ) 

How can you prove a conjecture is false?
