Answer:
The Area of a circle is
πr2=808.64
(3.14)r2=808.64
Divide both sides by 3.14
r2=257.5286624
Square root both sides to get radius
r=16 feet
Step-by-step explanation:
well first you could see how many words he types per min. (228/4 = 57)
so if x is the # of mins, y = 57x
good luck!
The <em><u>correct answer</u></em> is:
C.) old price was $170, new price is $159.12
Explanation:
The original price was $136. For a 25% markup, this means the amount of markup is 0.25(136) = 34. This makes the new price 136+34 = $170.
When they mark the price down to a 17% markup, this means the price is 0.17(136)+136 = 23.12+136 = $159.12.
Thank you for posting your question here. I hope the answer below will help.
Vo=110 feet per second
h0=2 feet
So, h(t) = -16t^2 +110t +2
Take the derivative: h'(t) = 110 -32t
The maximum height will be at the inflection when the derivative crosses the x-axis aka when h'(t)=0.
So, set h'(t)=0 and solve for t:
0 = 110 -32t
-110 = -32t
t=3.4375
t=3.44 seconds
