Answer:
B, Seth lost $261 by selling stocks.
Step-by-step explanation:
Since the income is negative, it would only be logical that he would've lost money, since you can't make negative money.
Answer:
m = 2 and n = 3
Step-by-step explanation:
We want to find the value of the integers m and n that will make the given expression true
(2x^ny^2)^m = 4x^6y^4
We can rewrite the left hand side of the equation as follows;
(2x^3y^2)^2
we can proceed to use inspection to ind the value of m and n
Through inspection since the left hand side of the equation now looks like the right hand side;
Then;
m= 2 and n = 3
Look at the unit circle and apply the hint. The x- and y-coordinates of each point are cosθ and sinθ, respectively. The radius of the unit circle is, of course, 1, and the center point is (0, 0).
General form of the parametric equations for a circle:
x = r·cosθ+h
and
y = r·sinθ+k
where r is the radius and (h, k) is the center. Therefore, the parametric equations for the unit circle are
x = cosθ
and
y = sinθ
:::::
The parametric equations
x = 2cosθ
and
y = 2sinθ
define a circle of radius 2, centered at the origin.
:::::
The parametric equations
x = 4cosθ
and
y = 2sinθ
define a horizontal ellipse centered at the origin, with transverse axis of length 8 and conjugate axis of length 4.
:::::
If a = b then
x = a·cosθ
and
y = b·sinθ
define a circle centered at the origin.
If a > b, then
x = a·cosθ
and
y = b·sinθ
define a horizontal ellipse centered at the origin.
If a < b, If a = b then
x = a·cosθ
and y = b·sinθ
define a vertical ellipse centered at the origin.
Answer: The radius of the new water tower is approximately 21 ft^3
Step-by-step explanation:
So we know the volume of the Water Tower is 66840 ft^3 and the new one's volume will hold 3/5 as much. so you will multiply 66840 by 3/5 to find the volume of the new one.
66840 * 3/5 = 40104 so the new water tower will hold 40104 cubic feet of water.
Now to find the radius we will use the formula v= 4/3r^3
40104 = 4/3 * * r^3
40104= 4.1887* r^3
r= 21
