Answer:
553.43 cm²
Step-by-step explanation:
This is a composite figure, so we will need to find the area of the semicircle separately from the area of the trapezoid and then add them together in the end.
Trapezoid
A = h(b1+b2)/2
A=8cm(20cm+30cm)/2
A=8cm(50cm)/2
A=400cm²/2
A=200cm²
Semicircle
r=d/2
r=30cm/2
r=15cm
A=(πr²)/2
A=(π×(15cm)²)/2
A=(π×225cm²)/2
A=353.4291735 cm²
Total Area
A=353.4291735 cm²+200cm²
A=553.43 cm²

Answer:
<h2>
h(x) = 0.0065x+1.25</h2>
Step-by-step explanation:
Given the time length in hours of a certain airplane flight represented by the function f(x) = 0.0025x + 0.75.
The time length of another airplane flight in hours can be represented by the function g(x) = 0.004x + 0.5.
x is the number of miles for the flight
The function that represents the sum of the flight time lengths is given as h(x) as shown;
h(x) = f(x) + g(x)
To get h(x), we will substitute the functions f(x) and g(x) into formula for function h(x) as shown below;
h(x) = (0.0025x + 0.75)+(0.004x + 0.5)
Collecting the like terms;
h(x)= 0.0025x + 0.004x + 0.75 + 0.5
h(x) = 0.0065x+1.25
This gives the sum of the flight time lengths
Answer:
(5+7x)°
(3+9x)°
