Answer:
a=1, b=-6, c=2, d=1
Step-by-step explanation:
You are given the function
Find the derivative:
The curve has a tangent line when x = 0 with equation y = 2x + 1, so
Hence,
The curve has a tangent line when x = 1 with equation y = -3x + 2, so
So,
From the second equation, a=-5-b, substitute it into the first one:
Answer:
For 4 seconds the projectile will be in the air.
Step-by-step explanation:
The function f(x) = –10(x)(x – 4) represents the approximate height of a projectile launched from the ground into the air as a function of time in seconds, x.
Now, if the projectile stays for x seconds in the air then after x seconds its height will be zero.
Hence, 0 = - 10x(x - 4)
⇒ x = 0 or x = 4
Now, x cannot be 0 as at time = 0 the projectile starts its motion.
So, for 4 seconds the projectile will be in the air. (Answer)
