Answer:

1)24.25

2)21

Step-by-step explanation:

1) (a/4)^2=(20/4)^2=25

b/2/8=6/8=3/4

25-3/4

=100/4-3/4

=97/4

=24.25

2)2(x-y)^2=2(3)^2=18

x-y=3

=18+3

=21

Hope this helps!

Brett golfs for the forestville knights high school team. When he practices his putting, he can make a 10-foot putt 80% of the t
balu736 [363]
The formula to calculate standard deviation from probability is \sqrt(n*p*(1-p)). n is the sample size, and 200 in this case (number of putts for practice). p is 80% or 0.8, the probability that he can make it. So the standard deviation is \sqrt(200*0.8*(1-0.8)=\sqrt(200*0.8*0.2)=\sqrt(16)=4.

A block is set in motion hanging from a spring and oscillates about its resting position
coldgirl [10]

Answer:

t = 1.277 sec and t = 2.848 sec

Step-by-step explanation:

This problem is much more easily done by graphing it than by computing it using algebra.

The values of t we're looking for are the ones that make x = 0, so we want the solutions of 0.6sin(2t)+0.4cos(2t)=0 on the interval [0, 3].

According to the graph, this is true when t = 1.277 seconds and t = 2.848 seconds.
