Answer:

The slope is 2

The y-intercept is 3

The equation is y = 2x +3

Step-by-step explanation:

The equation goes up 2 squares and over 1 square. 2/1 = 2

For y-intercept, look at the y-axis

The equation is supposed to be written as y = mx + b

m being the slope and b being the y-intercept.

A rugby player passes the ball 7.75 m across the field, where it is caught at the same height as it left his hand. At what angle

prisoha [69]

Answer-

At 15.91° the ball was thrown.

Solution-

In the question it is given that the ball was released and caught from the same height.

We know that,

$R=\frac{u^{2}\sin 2\Theta}{g}$

Where,

R = Range of the projectile = 7.75 m,

u = Initial speed = 12 m/s

θ = Angle at which it was released

g = Acceleration due to gravity = 9.8 m/s²

Putting all the values,

$\Rightarrow 7.75 = \frac{12^{2}\sin 2\Theta}{9.8}$

$\Rightarrow \sin 2\Theta=\frac{7.75 \times 9.8}{144} =0.5274$

$\Rightarrow 2\theta=\sin^{-1} 0.5274=31.83 \ or \ 148.17$

$\Rightarrow \theta=\frac{31.83}{2} \ or \ \frac{148.17}{2} =15.91 \ or \ 74.08$

$\Rightarrow \theta=15.91^{\circ} \ (smaller \ angle)$
