R - 4.5 < 11
—
r would be 15.5
[ r = 15.5 ]
B. 45 feet/second
To find out how fast it can go in 1 second, we divide it by 2
90 divided by 2 is 45, so the average speed of a baseball that is thrown 90 feet in 2 seconds is 45 feet/second
Wouldn’t it be the 7th root of 3? It’s a 30 60 90 triangle which means x=7 on that side so x on the bottom is the x root of three?
5 x 3/4 = 15/4
15/4 = 3 3/4
