Answer:
16 cm²
Step-by-step explanation:
The figure is a trapezoid with two parallel sides.
The formula for the area is
A = ½(a + b)h
Data:
a = 5 cm
b = 3 cm
h = 4 cm
Calculation:
A = ½(5 + 3) × 4 = ½ × 8 × 4 = 16 cm²
The area of the trapezoid is 16 cm².
Answer:
D.
Step-by-step explanation:
Here is where the answer is mentioned: "After the Civil War, the era known as Reconstruction began. During this era, the federal government tried to grant rights to former slaves and rebuild the South."
Every function associates input values with output values. The domain of a function is the set of all the inputs the function accepts.
You will basically always find your function graphed with the inputs on the horizontal axis and the outputs on the vertical axis. This means that every point on the graph has coordinates 
, and the domain is the set of all the x values.
The points on your red line have all coordinates 
, where d starts from 0 and ranges up to 12. So, the domain of the function is ![[0,12]](https://tex.z-dn.net/?f=%20%5B0%2C12%5D%20)
The length of RT=12÷2=6cm
the length of PT
6^2+PT^2=12^2
PT=√108
PT=10.392 decimal places
