(3 x a−3/4)∙1/3 if a=3/8
Dennis_Churaev [7]

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

General idea of how to do this
Anastaziya [24]
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.

Barbara is a research biologist for Green Carpet Lawns. She is studying the effects of fertilizer type, temperature at time of a
slega [8]

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 =6\times5\times3=90

Hence, the number of different lawn plots she needs in order to test each fertilizer type, temperature range, and water treatment configuration =90
