Answer:
-1/2
Step-by-step explanation:
The cosine is equal to the x coordinate of the point where the terminal side of the angle intersects the unit circle.
Answer:
m=10
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−7(2m−6)+21=−77
(−7)(2m)+(−7)(−6)+21=−77(Distribute)
−14m+42+21=−77
(−14m)+(42+21)=−77(Combine Like Terms)
−14m+63=−77
−14m+63=−77
Step 2: Subtract 63 from both sides.
−14m+63−63=−77−63
−14m=−140
Step 3: Divide both sides by -14.
-14m/-14=-140/-14
m=10
to find the area you have to do:
Area = π( D/2)^2 and in this case D = 19 so..
π(19/2)^2
=90.25π
=283.52873698648
Answer: 283.53
I looked at the other one you just asked and I couldn't figure it out. I understand this one.
Laney goes from 1 to 5, Gus from 1 to 6, Gus has the greater range. TRUE
Just eyeballing the data, Gus's median is 5, Laney's is 3. TRUE
Laney's data is more symmetrical, closer to the usual bell shape. Gus is heavily weighted toward the higher values, less symmetrical. TRUE
Answer:
17 , 65
Step-by-step explanation:
x+ y = 82
y = 4x - 3
=====================
Put the second equation into the first.
x + 4x - 3 = 82
5x = 85
x = 85/5
x = 17
17 + y = 82
x = 82 - 17
x = 65
