Answer:
f(x)=5cos(1/3x) this is an equation
Answer:
C(-3,1)=X1,Y1
D(5,6)=X2,Y2
Step-by-step explanation:
(distance)^2=(X2-X1)^2+(Y2-Y1)^2
=64+25
=89
Answer:
Step-by-step explanation:
Cosine (cos) is adjacent by hypotenuse. 
In any of the 45° angles, 1 is adjacent and √2 is the hypotenuse.
So arrange them to get
Answer:
1) 4
2) 45
3) 104
Step-by-step explanation:
1)
let x be your number.
((6x+8)/4)-5 = 3
add 5
(6x+8)/4=8
multiply by 4 to get rid of the denominator
6x+8=32
subtract 8
6x=24
divide by 6
x=4
2) Same type. (this time I won't explain every step)
let x be your number
((x/9)-8+6)*7 =21
(x/9)-8+6=3
(x/9)-2=3
x/9 = 5
x=45
3) Same type... Again
let x be your number
(((x-4+11)*2)/6)-8 = 29
((x-4+11)*2)/6=37
(x-4+11)*2 = 222
x+7=111
x= 104
