Answer:
4.2494369805536 km
Step-by-step explanation:
r = 4.2494369805536km because 26.7/2π which means:
26.7 ÷ 3.14159265359 x 2 = 4.2494369805536 km.
Answer:
209.2
Step-by-step explanation:
Step-by-step explanation:
We have, Sorin hits a cricket ball straight up into the air. After 1.5 s, the ball is falling straight down with a speed of 6.5 m/s.
We want to find the initial vertical velocity of the ball.
The relation between initial speed, final speed, acceleration and time is given by using first equation of kinematics. Let v₀ is the initial speed. So,
Here, v = -6.5 m/s, t = 1.5 s and a = -g
So, the initial velocity of the ball is 8.2 m/s and the formula used is (1).
F(x) = 20x+300
you sub in the x values (120 hours and 100 hours) for each equation
the only one they both work for is the last one
f(x) = 20x + 300
f(100) = (20 * 100) + 300 = 2000 + 300 = 2300
f(120) = (20 * 120) + 300 = 2400 + 300 = 2700
In Fahrenheit, the range at which this antifreeze protects the car, is between -40 degrees F and 257 degrees F.
