Step-by-step explanation:

So you would have f(3) = 3 + $\frac{2}{2}$

f(3) = 3 + 1

f(3) = 4

what is the probability of hitting each target if it is assumed that a player’s throw will always hit the board? hint: the proba

solong [7]

Because the actual dimensions of the board and the target are missing, let us supply the missing values.

Let:

radius of board = 6 inches
radius of target = 2 inches

Area of board = pi * r^2 = pi*6^2 = 36pi
Area of target = pi * r^2 = pi*2^2 = 4pi

Probability of hitting the target = 4pi / 36pi = 1/9

Therefore, there is a 1/9 chance of hitting the target on the board.

An engineer is designing a runway for an airport. Several planes will use the runway and the engineer must design it so that it

swat32

Answer:

d=117.33 m

Step-by-step explanation:

Initial velocity of planes, u = 0 (because they are at rest)

Acceleration, a = 3.3 m/s²

Final take off speed, v = 88 m/s

We need to find the minimum allowed length for the runway. Let it is d. d will be the distance. It can be calculated using third equation of motion as follows :

$v^2-u^2=2ad\\\\d=\dfrac{v^2-u^2}{2a}$
