A ball is hit vertically upwards from a cliff, which is 80 m above the sea. The displacement
Stels [109]

Answer:

a) 8 seconds

b) 3 seconds

c) 170 meters

Step-by-step explanation:

a) When the ball lands in the sea, s = -80.

-80 = 30t − 5t²

5t² − 30t − 80 = 0

t² − 6t − 16 = 0

(t + 2) (t − 8) = 0

t = -2 or 8

t = 8 seconds

b) The ball reaches its highest point when the velocity is 0 (or at the vertex of the parabola).

t = -b / (2a)

t = -30 / (2 × -5)

t = 3 seconds

c) The highest point is:

s = 30(3) − 5(3)²

s = 45

So the ball rises 45 meters, falls 45 meters, then falls 80 meters.

The total distance traveled is 45 + 45 + 80 = 170 meters.

Figure PQRS is a parallelogram. The expressions represent the measures of the angles in degrees. Parallelogram P Q R S is shown.
ch4aika [34]

Answer:

20°

Step-by-step explanation:

the sum of the angles gives 180°

20+2x+6x=180

20+8x=180°

8x=180-20

x=160°÷8°

x=20°

What is the area of the circle below, in terms of ?90 metersO 457O 907O 1807O 81007134
defon

Step 1: Write out the formula

\begin{gathered} \text{Area of a circle = }\pi r^2 \\ \text{where } \\ r=\text{ the radius of the circle} \end{gathered}

Step 2: Write out the given values and substitute them into the formula

r=90m

Therefore,

\text{ the area of the circle = }\pi(90)^2=\pi\times8100=8100\pi m^2

Hence, the area in terms of pi is

8100\pi

The last choice is the correct answer
