Answer:

Perimeter =28 units.

Area = 45 unit^2.

Step-by-step explanation:

The length of first side (joining first 2 points) = 5 - (-4) = 9 (as y coordinates are both -5)

The line joining the 2nd and third points = 0 - (-5) = 5

The line joining the 3rd and 4th points = 5 - (-4) = 9.

The line joining the first and 4th points = 0 - (-5) = 5

So the perimeter = 2(5) + 2(9)

= 28 units.

Area = 5*9 = 45 unit^2.

What is 85% of 420?

prohojiy [21]

You turn 85% into a decimal
then multiply the decimal by the main number.
420x.85=357.

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,

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

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

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

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

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