Answer:
139
Step-by-step explanation:
first you need to find the x:
180= 8x + 51 + 6x - 25
180 - 51 +25 = 8x + 6x
154 = 14x
154/14 = x = 11
then you have to work out AOB:
8x +51
8(11) +51
88+51 = AOB = 139
to check your work, workout angle BOC and add both. angles together to check if you get 180:
BOC= 6x - 25
6(11) - 25
66 - 25 = 41
To check:
BOC + AOB = 180
41 +139 = 180
180 = 180
Hope this helps!
Answer:
It is f(x) = -x^2 + 2x + 4.
Step-by-step explanation:
As it has a maximum the coefficents of x^2 will be negative.
f(x) = -x^2 + 2x + 4
The y-intercept occurs when x = 0 so
y-intercept = 0 + 0 + 4 = 4.

The shop had $2,000 in sales on Monday.
If it fell by 10% on Tuesday, then 2000 * 0.10 equals the percentage it dropped, so it dropped by $200. So they only had $1,800 in sales on Tues.
If they fell by another 20% on Wednesday, 1,800 * 0.20 equals a $360 drop. Now we're at $1,440.
The sales then increased by 25% of Monday's total # of sales. 25% of Monday's sales is 2,000 * 0.25 which equals a $500 increase. Now we're at $1,940.
Now that we're done with everything, how far are we from the beginning? That's the net change. :) We began at $2,000 on Monday, and ended with $1,940 on Thursday. 2000 - 1940 is 60, so 60 = your net change.
TLDR: Sold $2,000 on Mon, sold $1,800 on Tues, sold $1,440 on Wed, and then sold $1,940 on Thurs. The net change is $60.
