Answer:
Midpoint of the circle is (-3, -7)
Distance from (3, 4) to (-3, -7) is > 5 because the x and y difference are alone greater 5.
So, "In the exterior of the circle" is correct.
60/10=6f/s
42/6=7f/s
7>6, so the person who walks 42 feet in 6 seconds is faster. :)
Answer:
I'm going to also give you how to get the answer... not just the answer.. you will need to know this for a test :/ so learn it :P
Step-by-step explanation:
Sin(30)=12
to remember what Sin and Cos at those speacial angles in degrees are.. just use this Sin(degrees)
Sin(0) = 0/2 =0
Sin(30)= /2 = 1/2
Sing(45) = /2 = /2
Sin(60)=/2 = /2
Sin(90)=/2 = 1
Cos is exactly the same but counts backwards from 90°
Cos(90) = 0/2 =0
Cos(60) = /2 = 1/2
Cos(45) = /2 = /2
Cos(30) = /2 = /2
Cos(0) =/2 = 1
note that the numerators just count from 0,1,2,3,4 , see? you can remember sin and cos now :) since you can count to 4 :P
Sin(30) =12
1/2 =12 while that statement makes no sense.... obviously 1/2 isn't equal to 12 but.. what's being said is that the angle of 30° gives you a side that is 12 units long.
so looking at what I wrote above.. which angle in degrees matches Sin when you look at Cos?
Sin(30)= 1/2 and Cos(60) also = 1/2 huh
sooo β = 60 °
got it? :/
Answer:
Assuming the problem is actually 5x^2-3y... the answer is 221
Step-by-step explanation:
5(7 times 7) is 245 and 3(8) is 24, therefore 245-24=221
