Yes it's a function.
the domains and ranges are {(1,6),(2,2),(5,-3),(6,-7)}
the domain are the x numbers so, (1,2,5) are your x's
the rangers are the y numbers so, (6,2,-3)
Answer:
1.28 or 912/715
Step-by-step explanation:
sine= opposite side/hypotenuse
cos=adjacent/ hypotenuse
sine a= 12/13 using the Pythagorean Theorem and solve for the missing side. (which is the adjacent side)
cos a = 5/13
Do the same for sine b
cos b= 9.8/11
add both the cosine value
(5/13)+(9.8/11)=1.28 or 912/715 in fraction form
Answer:
b = -4 and 0
Step-by-step explanation:
Using the distance formula
D = √(x2-x1)² + (y2-y1)²
√8 = √(b-2)² + (3-1)²
√8 = √(b-2)² + 2²
Square both sides
8 = (b-2)² + 2²
8 = (b-2)² + 4
8 - 4 = (b-2)²
4 = (b-2)²
Square root both sides
±√4 = b- 2
±2 = b - 2
b = -2 - 2 and b = -2 + 2
b = -4 and 0
This gives the values of b
Answer:
see explanation
Step-by-step explanation:
Using the sine/ cosine ratios in the right triangle and the exact values
sin30° = , cos30° = , then
sin30° = = = = ( cross- multiply )
AB = 12
cos30° = = = = ( cross- multiply )
2 AC = 12 ( divide both sides by 2 )
AC = 6
