Answer: B
Step-by-step explanation:
Answer:
- always start off with exponents.<em> a number</em>^2 means a number times itself.
- Next, multiply the previous number by 3.
- Now, add the product of the previous equation, and the sum of 3 times <em>x</em>.
- Next, find the value of 4 times <em>x</em>, and subtract it from the products of the previous two numbers.
- Now that we have the values of these 3 numbers, multiplied, added, and subtracted, add 5 onto the current value.
- Finally, subtract the value of all the previous numbers by 1.
Hope this helps in every way!
Answer:
f(t) = 15.06 m
Step-by-step explanation:
The relationship between the height of the rocket and the time after launch, t. In seconds is given by :
We need to find the maximum height the rocket will reach the ground.
When it reaches the ground,
f(t) = 0
So,
Maximum height,
f'(t) = 0
Put t = 1.63 in equation (1).
So, the maximum height of the rocket is 15.06 m.
