Answer:
an=9+(n−1)3, an=3n+6
Step-by-step explanation:
Arithmetic Sequence:
d=3
This is the formula of an arithmetic sequence.
an=a1+d(n−1)
Step 1: Substitute in the values of
a1=9 and d=3.
an=9+(3)(n−1)
Step 2: Simplify each term.
an=9+3n−3
Step 3: Subtract 3 from 9.
an=3n+6
Answer:
Solve a system of equations with two unknowns x and y
where x is the rental price for the movie and y is the rent for video games
7x + 9y = 73
5x + 3y = 29
Solving the result: x = $ 1.75, y = $ 6.75

Answer:
= 18.857 cm²
Step-by-step explanation:
The area of a segment is given by;
θ/360 × 2πr². where θ is the angle subtended by the arc to the center of the circle and r is the radius of the circle.
θ = 60, and r = 6
Therefore;
Area = 60/360 × 22/7 × 6²
= 18.857 cm²
the answer is 2.3
10 to the first power is 10
0.23*10 is 2.3
