Hello.


Firstly, 4 percent of 100 is 0.04 percent, and given the equation y = 3000(1 + 0.03)^n, you replace the 0.03 with 0.04.


Therefore, the answer is C, y = 3000(1 + 0.04)^n.

Answer:

42ft

Step-by-step explanation:

Area of a triangle = 1/2 * base * height

So that little triangle section:

 1/2 * 2 * 3 = 1/2 * 6 = 3

Now we do the rectangle Section:

Area of a rectangle = length * width

So that rectangle is 3 * 7 = 21

If you eliminate those two shapes, you are left with a trapezoid.

Area of a trapezoid is 1/2 * (base 1 + base 2) * height

Base 1 is 3 which is the width of the rectangle.

Base 2 is the 6.

The height is the given 11 feet subtracted by the 7 feet from the length of the rectangle which is 4.

Plug all this in to the formula you get 1/2 * (6 + 3) * 4 = 1/2 * 9 * 4 = 1/2 * 36 = 18.

Now add all of your areas together;

21 + 3 + 18 = 24 + 18 = 42

mojhsa [17]
We have the following product:
 -2x ^ 2y ^ 3 · 14x ^ 2y ^ 3
 For power properties we have:
 "same base add the exponents"
 We have then:
 (-2 * 14) (x ^ (2 + 2)) (y ^ (3 + 3))
 -28x ^ 4y ^ 6
 Answer:
 
The product -2x ^ 2y ^ 3 · 14x ^ 2y ^ 3 is:
 
-28x ^ 4y ^ 6

Express (1-2i) second power in the form a+bi
Zigmanuir [339]

\bf (1-2i)^2\implies (1-2i)(1-2i)\implies 1-2i-2i+(2i)^2 \\\\\\ 1-4i+(2^2i^2)\implies \stackrel{\textit{recall }i^2=-1}{1-4i+(4\cdot -1)}\implies 1-4i-4\implies \boxed{-3-4i}

Find the perimeter of the polygon with the vertices X(−1, 3), Y(3, 0), and Z(−1,−2). Round your answer to the nearest hundredth
antoniya [11.8K]

Answer:

The perimeter of the polygon is P=14.47\ units

Step-by-step explanation:

we know that

The perimeter is the sum of the length sides of the polygon

In this problem

P=XY+YZ+XZ

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

step 1

Find the distance XY

we have

X(−1, 3), Y(3, 0)

substitute

d=\sqrt{(0-3)^{2}+(3+1)^{2}}

d=\sqrt{25}

dXY=5\ units

step 2

Find the distance YZ

we have

Y(3, 0), Z(−1,−2)

substitute

d=\sqrt{(-2-0)^{2}+(-1-3)^{2}}

d=\sqrt{20}

dYZ=4.47\ units

step 3

Find the distance XZ

we have

X(−1, 3), Z(−1,−2)

substitute

d=\sqrt{(-2-3)^{2}+(-1+1)^{2}}

d=\sqrt{25}

dXZ=5\ units

step 4

Find the perimeter

P=XY+YZ+XZ

P=5+4.47+5=14.47\ units
