Answer:
The answer is B
Step-by-step explanation:
1. 2.50 x 2 is $5
2. 2.50 x 4 is $10
3. 2.50 x 3 is $7.50
4. 5 + 10 + 7.50 is 22.50 so you know the total should be 22.50.
5. It cant be A because 2.50 x 2 is 5 then timesing that by four would make 20 and then by 3 that would make $60 not $22.50
6. It is B because 2 + 4 + 3 is 9, 9x2.50 is 22.50
The equation of the circle would be (x−(−4))2+(y)2=6or (x+4)2+(y−72=36.
Explanation:The equations of the circle is(−h)2+y−k)2=r2
where h is the x of the center of the circle and k is the y of the center of the circle, and r is the radius(-4,7) radus is 6h = -4k = 7r = 6plug in the values(x−(−4))2+(y−7)2=62simplify(x+4)2+(y−7)2=36.
Those are all lines...
So the x interval is from -2 to 3, because of x=-2 and x=3
The upper line is y(u)=4x and the lower line is y(l)=x-5
So the area between the two lines is:
A=⌠y(u)-y(l) dx
A=⌠4x-x+5 dx
A=⌠3x+5 dx
A=[3x^2/2+5x]
A=[(3x^2+10x)/2], x=[-2,3]
A=(1/2)(27+30-(12-20))
A=(1/2)(57+8)
A=(1/2)(65)
A=32.5 u^2
No 2/3 of $21 is $14 so 6x14 is $84 less than $110
