Step-by-step explanation:
It's an arithmetic sequence.
9 = 11 - 2
7 = 9 - 2
5 = 7 - 2
3 = 5 - 2
A) next three terms: 3 - 2 = 1, 1 - 2 = -1, -1 - 2 = -3
B) Common difference = -2
C) Recursive Function:
D) Explicit Function:
a₁ - first term
d - common difference
Substitute a₁ = 11 and d = -2:
The area of triangle B is 10.5 square units.
The area of triangle C is 10 square units.
Step-by-step explanation:
Step 1:
The area of a triangle is half the product of its base length and height.
The base is the lower end of the triangle and its length is called base length.
The length from the base to the highest point on the triangle is the height.
Step 2:
For triangle B, the base extends for a length of 7 units and the height is 3 units.
The area of triangle B
So the area of triangle B is 10.5 square units.
Step 3:
For triangle C, the base extends for a length of 5 units and the height is 4 units.
The area of triangle C
So the area of triangle C is 10 square units.
