Answer:
y= 1/3x +3
Step-by-step explanation:
slope: 4-1/3-(-6) =3/9=1/3
point slope: y-4=1/3(x-3)
y-4=1/3x -1
y=1/3x +3
Answer:
220 degree
Step-by-step explanation:
Given the radius=18cm , pi=3.14.. , area=198π
Area of a sector =∅×π×r²/360
or,198π=Θ×π×r²/360
or,Θ=360×198π/πr²
∴Θ=220°
Right now his test scores average to 78.5 which mean if he wants to get an 80 for the final average, the lowest he can score is 94%
Answer:
Part 1: 25 feet long
Part 2: 8 feet high
Step-by-step explanation:
A^2 +B^2 =C^2
C is the hypotenuse which you are finding for part 1.
You are finding B for part 2.
Part 1:
15^2 + 20^2 = C^2
225+400=C^2
625=C^2
Sqrt(625)= C
25=C
Answer for Part 1 is 25 feet long.
Part 2:
6^2 + B^2 = 10^2
36 + B^2 = 100
Subtract 36 from both sides.
B^2 = 64
B= sqrt(64)
B= 8
Answer for Part 2: 8 feet high
Not 100% sure if this is correct but the answer is X=-7/5.
