12% of 4,000 = 480
4,000 * 3 = 12,000
480 * 3 = 1,440
12,000 + 1,440 = 13,440
So...at the end of 3 years, $13,400 is due.
Hope I helped! Please mark Brainliest if correct; I would greatly appreciate it. :)
Uhh, answer choices?
In any case, since
is inscribed in a semicircle, it is a right triangle (due to the inscribed angle theorem). Thus, by the Pythagorean theorem,
Now, the circumradius of a right triangle (the radius of the circle passing through all three of its vertices) is simply half its hypotenuse, so ![OJ=OK=OL=\frac{\sqrt{157}}{2}\approx \boxed{6.265}.](https://tex.z-dn.net/?f=OJ%3DOK%3DOL%3D%5Cfrac%7B%5Csqrt%7B157%7D%7D%7B2%7D%5Capprox%20%5Cboxed%7B6.265%7D.)
Let the three apartments be A, B & C
The rent of A is $x
The rent of B is $y
The rent of C is $z
So x + y + z = 1600 .......(1)
Now
Maintenance of A is 20% of x = 0.20x
Maintenance of B is 20% of y = 0.20y
Maintenance of C is 25% of z = 0.25z
0.20x + 0.20y + 0.25z = 345
Multiplying by 100 we get
20x + 20y + 25 z = 34500
Dividing by 5 we get
4x + 4y + 5z = 6900 .......(2)
Monthly fee of A is 10% of x = 0.10x
Monthly fee of B is 20% of y = 0.20 y
Monthly Fee of C is 10% of z = 0.10z
Now
0.10x + 0.20y + 0.10 z= 1820 - 1600
0.10x + 0.20y + 0.10z = 220
Multiplying by 100 we get
10x + 20y + 10z = 22000
Dividing by 10
x + 2y + z = 2200 ....(3)

is the required matrix
Answer: 21y^5-28y^4+49y^3
If the remainder isn't necessarily zero, we add C_1y^2+C_2y+C_3, which covers all possible remainders when dividing by a polynomial with leading term in y^3.
Step-by-step explanation:
(3y^2-4y+7)(7y^3) =
21y^5-28y^4+49y^3
Answer:
You can tell that the maximum value that attains is rough.
Rewriting in vertex form. This tells us that the maximum of is.
So has the greater maximum.
