Answer:
The rocket will reach its maximum height after 6.13 seconds
Step-by-step explanation:
To find the time of the maximum height of the rocket differentiate the equation of the height with respect to the time and then equate the differentiation by 0 to find the time of the maximum height
∵ y is the height of the rocket after launch, x seconds
∵ y = -16x² + 196x + 126
- Differentiate y with respect to x
∴ y' = -16(2)x + 196
∴ y' = -32x + 196
- Equate y' by 0
∴ 0 = -32x + 196
- Add 32x to both sides
∴ 32x = 196
- Divide both sides by 32
∴ x = 6.125 seconds
- Round it to the nearest hundredth
∴ x = 6.13 seconds
∴ The rocket will reach its maximum height after 6.13 seconds
There is another solution you can find the vertex point (h , k) of the graph of the quadratic equation y = ax² + bx + c, where h = and k is the value of y at x = h and k is the maximum/minimum value
∵ a = -16 , b = 196
∴
∴ h = 6.125
∵ h is the value of x at the maximum height
∴ x = 6.125 seconds
- Round it to the nearest hundredth
∴ x = 6.13 seconds

Answer:
650.
Step-by-step explanation:
ok so first multiply the Length and the width of the rectangle together to get its area, which is 500.
to find the area of the triangle, just multiple the length times the width (15 x 20) and divide it by two. You should get 150.
Add 150 and 500 together, and that's your total area:
650.
Have a nice day dude
Full time yes = 70 no = 15
part time yes = 25 no = 25

➷ Figure out what you would need to do to get from 2.5kg to 1kg
You would need to divide by 2.5
Just divide the cost by this value:
2.5/2.5 = 1
1kg would cost £1.00
