Answer:
135 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A =
h(a + b)
where h is the height and a, b the parallel bases
Here h = 9, a = 13 and b = 17 , thus
A =
× 9 × (13 + 17)
= 0.5 × 9 × 30
= 135 cm²
Answer:
The average rate of change between x = 2 and x = 4 is of 4.
Step-by-step explanation:
Average rate of change:
The average rate of change of a function f(x) in an interval [a,b] is given by:

In this question:

Thus:


Average rate of change:




The average rate of change between x = 2 and x = 4 is of 4.
Unit rate means how much does it cost for 1 unit
2.64 for 12 pencils
find 1 pencil
divide both sides by 12
0.22 for 1 pencil
0.22 per pencil
