Step-by-step explanation:
I hope it's correct.. And hopefully you understand those steps and also my horrible writing
Area of circle: A=pi×r². This area coresponds to 360degrees, or 2×pi radians.
2×pi ....... pi×r²
t radians....x
where t=2.75rads
Area of t: x=pi×r²×t/2/pi=r²×t/2
Area of t: 3²×2.75/2=9×2.75/2=12.375
Answer: the area of 2.75 radians is 12.375
Answer:
The correct answer would be D. y+2=1/2(x+3)
Step-by-step explanation:
Point slope form can be written as y-y1=m(x-x1)
Since m is slope, we can see from the equation in slope intercept form that the slope is 1/2, so we can insert that into our equation. The rest is simply the process of inserting the values from the point on the graph into the equation.
Since y1=-2, we could put that as y--2 or y+2, since negatives cancel out.
Then we can replace x1 with -3, resulting in x--3 or x+3.
So our resulting equation is:
D.y+2=1/2(x+3)
Hope this helps!
Answer:
marcel picked 4 apples
Step-by-step explanation:
18 = 4x + 2
solve for x
subtract 2 from each side
16 = 4x
divided by 4
16/4 = 4
