Mathematics

Alekssandra [29.7K]3 years ago

Answer:

4. +4 , -4

Step-by-step explanation:

I did number 4 and 6 instead.

4. x^{2} +32=16

do opposite of +32 to even out equation, so subtract 32 from 16, 16-32= -16

no u have x^2 = -16

to get rid of the exponent we must do the opposite of it, a square root, to both sides. so the square root of -16 is x= +4 or -4

The projectile motion of an object can be modeled using s(t) = gt2 + v0t + s0, where g is the acceleration due to gravity, t is
WARRIOR [948]

Answer:

s(t) = -4.9t² + 39.2t

Step-by-step explanation:

Given the projectile motion of an object can be modeled using s(t) = gt2 + v0t + s0, where g is the acceleration due to gravity, t is the time in seconds since launch, s(t) is the height after t seconds, v0 is the initial velocity, and s0 is the initial height. The acceleration due to gravity is –4.9 m/s²

Given

g = -4.9m/s²

v0 = 39.2m/s

s0 = 0m (the initial height)

On substituting into the formula;

s(t) = gt² + v0t + s0

s(t) = -4.9t² + 39.2t + 0

s(t) = -4.9t² + 39.2t

This gives the equation that models the height

mel-nik [20]
3 cm on the map represents 31.5 km in reality.

3cm : 31.5 km

1cm :  31.5/3 km

1cm : 10.5km

So the scale on the map is 1cm represents 10.5 km.
