A rock is thrown upward with a velocity of 17 meters per second from the top of a 31 meter high cliff and it missies the cliff o

Vinvika [58]

Answer:

$4.5\ \text{s}$

Step-by-step explanation:

t = Time taken

u = Initial velocity =17 m/s

v = Final velocity

s = Displacement

a = Acceleration

g = Acceleration due to gravity = 9.81 m/s² = a

$v^2-u^2=2as\\\Rightarrow s=\dfrac{v^2-u^2}{2a}\\\Rightarrow s=\dfrac{0^2-17^2}{2\times -9.81}\\\Rightarrow s=14.73\ \text{m}$

Total height the rock is to fall when it is 8 meters from the ground is $14.73+(31-8)=37.73\ \text{m}$

$v=u+at\\\Rightarrow t=\dfrac{v-u}{a}\\\Rightarrow t=\dfrac{0-17}{-9.81}\\\Rightarrow t=1.73\ \text{s}$

Time taken to reach the maximum height is 1.73 s.

$s=ut+\dfrac{1}{2}at^2\\\Rightarrow 37.73=0+\dfrac{1}{2}\times 9.81t^2\\\Rightarrow t=\sqrt{\dfrac{37.76\times 2}{9.81}}\\\Rightarrow t=2.77\ \text{s}$

Time taken from the maximum height to the point which is 8 m from the ground is 2.77 s.

So, time taken from the moment of the throw to the point 8 m from the ground is $1.73+2.77=4.5\ \text{s}$ .

Select the correct answer.

anygoal [31]

Answer:

B: $c(3c^2-4)$

Step-by-step explanation:

1. Substitute $1$ for c: $(24^6-32^4)/(8^3)$

2. Solve substitution: $-1$

3. Compare $-1$ to calculated answers when $c=1$

4. $c(3c^2-4)$ when $c=1$ is $-1$

Brandon is thinking of a number that is divisible by 6 and 8 . What is the smallest number that Brandon could think of

a_sh-v [17]

since

6 = 2 * 3 <--- two factors

8 = 2 * 2 * 2 <--- three factors

and since the "2" is there on each, then we can just use that instance of it once.

so instead of using 2 * 3 * 2 * 2 * 2, we'll use 2 * 3 * 2 * 2, and that is our LCD.

2 * 3 * 2 * 2 = 24.

Answer:

Angle one and angle 2 are complementary, since together they add up to 90 degrees.

Step-by-step explanation:

Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.
