Radius is 1/2 of the diameter.

If The circ is 64. Divide it by Pi 64/3.14= circle’s diameter of 20.38. Radius is 1/2 of diameter 10.19

4.2x−1.4y=2.1 in terms of y
Alona [7]
To find Y we must cancel X out by making it 0.

4.2(0) - 1.4y = 2.1

-1.4y = 2.1

Divide both sides by -1.4 to get the Y by itself.

Y = 2.1/-1.4
Y = -1.5

Median of 28, 30, 34, 35
Arturiano [62]
You first put them all in order from least to greatest. Now, since 30 and 34 seem to be in the middle, write the number in between them: 30, 31, 32, 33, 34.

And you get your answer as 32. Hope this helped ;)

A blueberry pie is shot out of a pie cannon from a height of 6m and with a velocity of 60 m/s. How many seconds will pass before
sveta [45]

Answer: 1.106 s

Step-by-step explanation:

This situation is related to projectile motion and one the equation that models the height of the blueberry pie in time is:

y=y_{o}+V_{o}sin(\theta) t-\frac{1}{2}gt^{2}

Where:

y=0 m is the blueberry pie final height (when it hits the ground)

y_{o}=6 m is the blueberry pie initial height

V_{o}=60 m/s is the blueberry pie initial velocity

\theta=0 \° is the angle, assuming the pie was shot horizontally

t is the time

g=9.8 m/s^{2} is the acceleration due gravity

Rewriting the equation:

0=y_{o}-\frac{1}{2}gt^{2}

Isolating t:

t=\sqrt{\frac{2y_{o}}{g}}

t=\sqrt{\frac{2(6 m)}{9.8 m/s^{2}}}

Finally:

t=1.106 s
