AOB (Major) = 360 - (60+60) = 240°

Length of arc =
\frac{Angle\: subtended \:by \:arc}{360} \times 2 πr \\ \frac{240}{360} \times 2 \times \frac{22}{7} \times 6 \\ \frac{2}{3} \times 2 \times \frac{22}{7} \times 6 \\ \frac{24 \times22 }{21} \\ = 25.14

Answer will be B. 25.13 as this is very close to our answer.

Solve the equation 2x^{2}+9x-1=x to the nearest 10th
Scilla [17]

Answer:

2x2+9x−1=x

Step 1: Subtract x from both sides.

2x2+9x−1−x=x−x

2x2+8x−1=0

Step 2: Use quadratic formula with a=2, b=8, c=-1.

x=

−b±√b2−4ac

2a

x=

−(8)±√(8)2−4(2)(−1)

2(2)

x=

−8±√72

@jdoe<br><br> As promised. The link will be whatever.

Ok, so we see in
y=a(x-h)^2+k
vertex is (h,k)
vertex is highest or lowest point
on one side, it goes up and other side it goes down

if a is positive, then it goes down then up
if a is negative, it goes up then down

we see
f(x)=2(x+3)^2+2
2 is positive
goes down then up
vertex is (-3,2)

so decreases from -infinity to -3 or ininterval
(-infinity,-3)

answer is first option
