Answer:
f(n) = f(n - 1) + 3
Step-by-step explanation:
Substitute 
to get the recursive formula.
OPTION 1: f(n) = f(n - 1) + 3
Substituting n = 1.
f(1) = f(1 - 1) + 3 = 0 + 3 = 3.
Substituting n = 2.
f(2) = f(2 - 1) + 3 = f(1) + 3 = 3 + 3 = 6.
Substituting n = 3.
f(3) = f(3 - 1) + 3 = f(2) + 3 = 6 + 3 = 9.
The numbers match the given sequence. So, we say the above recursive formula represents the sequence.
OPTION 2: f(n) = f(n - 1) + 2
Substituting n = 1
f(1) = f(0) + 2 
3.
So, this is eliminated.
Similarly, OPTION 3 and OPTION 4 can be eliminated as well.
She has $12,488 in savings
Step-by-step explanation:
Ariana plans to use $260 less than three-fourths of savings to buy a car.
If the purchase price of the car is 9,340, we need to find how much
she has in savings
To find the savings
- Assume that she has $x in savings
- Write an equation of x
- Solve the equation to find x
∵ She has $x in savings
∵ She plans to use $260 less than three-fourths of savings
- Three-fourths means 
and less than means subtract
∴ She plans to use x - 26
∵ The purchase price of the car is 9,340
- Equate the expression of x by 9,340
∴ x - 26 = 9,340
Now let us solve the equation
∵ x - 26 = 9,340
- Add 26 to both sides
∴ x = 9,366
- Divide both sides by
∴ x = $12,488
She has $12,488 in savings

Answer:
73.5 yd squared
Step-by-step explanation:
The formula for finding an area of a triangle is Base x Height divided by 2, so 21 x 7 = 147 and dividing that by 2 gets you 73.5.
