Answer:
1 3/8
Step-by-step explanation:
Possible derivation:
d/dx(1/8 (-2 + 3 x))
Factor out constants:
= 1/8 (d/dx(-2 + 3 x))
Differentiate the sum term by term and factor out constants:
= 1/8 d/dx(-2) + 3 d/dx(x)
The derivative of -2 is zero:
= 1/8 (3 (d/dx(x)) + 0)
Simplify the expression:
= 3/8 (d/dx(x))
The derivative of x is 1:
Answer: = 1 3/8
The general approach to this is to write the (x, y) coordinates of the trajectory's peak in terms of the sine and cosine of the launch angle α. Then use a trig identity (sin(2α)² + cos(2α)² = 1) to eliminate the dependence on α.
You should get
t = v₀sin(α)/g
x = v₀²sin(2α)/(2g)
y = v₀²(1-cos(2α))/(4g)
Solve each of the latter two equations for the trig function, then substitute those expressions into the trig identity above. Divide by the coefficient of x² and rearrange to get the expression shown.
Answer: 90
Step-by-step explanation:
Given : The number of fertilizer types = 6
The number of temperature zones =5
The number of water treatments=3
The number of different lawn plots =
Hence, the number of different lawn plots she needs in order to test each fertilizer type, temperature range, and water treatment configuration =90
