Hi.
For this, you do:
4% of 7500 = 300
He is given $300 per year, for two years.
1st year= 7500+300= 7800
2nd year= 7800+300= 8100
answer= $8100
Hope this helps:)
I found the image that accompanied this problem.
We need to solve for the area of the sector.
A = n/360 * π * r²
A = 85/360 * 3.14 * 5²
A = 0.2361 * 3.14 * 25
A = 18.5347
Answer is C. 18.5 square meters.
<span>3x^2 + 10xy + 8y^2 + 14x + 22y + 15 = 0
3x^2 is factorable only as 3x and x.
15 can be 15 * 1 or 3 * 5.
As a first guess, I place 5 and 3 in that order.
The coefficients of y are unknown so far.
= (3x + Ay + 5)(x + By + 3)
= 3x^2 + 3Bxy + 9x + Axy + ABy^2 + 3Ay + 5x + 5By + 15
(3B + A)xy = 10xy
(3A + 5B)y = 22y
A + 3B = 10
3A + 5B = 22
-3A - 9B = -30
3A + 5B = 22
4B = 8
B = 2
A + 3B = 10
A + 6 = 10
A = 4
</span>
3x^2 + 10xy + 8y^2 + 14x + 22y + 15 = <span>(3x + 4y + 5)(x + 2y + 3)
The product of </span><span>(3x + 4y + 5)(x + 2y + 3) is indeed
</span><span>3x^2 + 10xy + 8y^2 + 14x + 22y + 15
The lines are
</span><span>3x + 4y + 5 = 0
x + 2y + 3 = 0</span>
