Answer:

$143.8\:\mathrm{ft^2}$

Step-by-step explanation:

The composite figure shown in the picture consists of a semi-circle and a trapezoid. We can even break this trapezoid into a rectangle and two triangles for even simpler calculations. We can find the total area of the figure by simply adding the total area of the shapes we will break the figure into:

Area of semi-circle (half the area of a circle): $\frac{1}{2}\cdot 4.5^2\cdot \pi$

Area of trapezoid (average of bases multiplied by height): $16\cdot 7$

Thus, the total area of the figure is:

$\frac{1}{2}\cdot 4.5^2\cdot \pi+16\cdot 7=143.808625618\approx \boxed{143.8\:\mathrm{ft^2}}$

Given z1 and z2, what is the midpoint?<br><br> z1=5-7i and z2=-9+3i.

sveta [45]

Answer:

$7-2i$

Step-by-step explanation:

As you're used to do in the real plane, midpoint is the average of Real and Imaginary part. So $\frac{5+9}2 +i \frac{-7+3}2 = \frac{14}2+i\frac{-4}2 = 7-2i$
