Answer:

The 2nd term in the sequence is -9.

Step-by-step explanation:

We have that:

a(1) = -13

a(n) = a(n-1) + 4

Find the 2nd term in the sequence.

This is a(2). So

a(2) = a(2-1) + 4

a(2) = a(1) + 4

Since a(1) = -13.

a(2) = -13 + 4 = -9

The 2nd term in the sequence is -9.

Answer:

The 2nd term in the sequence is -9.

Step-by-step explanation:

fa(1) = -13

a(n) = a(n-1)+4

Find the 2nd term in the sequence.

The sequence is an Arithmetic sequence.

Here the 1st term = -13

An = A(n-1) + 4

Therefore, the common difference (d) = 4

2nd term = first term + common difference

2nd term = -13 + 4 = -9

The answer is -9.

THEREFORE, The 2nd term in the sequence is -9.

During a sale, 20-cent candy bars were sold at 3 for 50 cents. How much is saved on 9 bars?
Mazyrski [523]

Answer:

Step-by-step explanation:

$0.30

Step-by-step explanation:

1 bar of candy = $0.20

3 bars of candy = $0.50

To solve, multiply for both:

If you pay for each candy bar individually, they each cost $0.20. Multiply 9 with 0.20:

9 x 0.20 = $1.80

If you pay for the candy bars by 3's, they cost $0.50 each pack. Divide 9 with 3, then multiply by 0.50:

9/3 = 3

3 x 0.50 = $1.50

Subtract the total cost of the individual from the pack:

$1.80 - $1.50 = $0.30

. $0.30 is your answer.

Prakash bought a new car at the dealership for $27,000. it is estimated that the value of the car will decrease 7% each year. wh
Dennis_Churaev [7]

The exponential function models the value v of the car after t years is V = 27000 * (0.93)^t

<h3>How to determine the exponential model?</h3>

The given parameters are:

Initial value, a = $27,000

Depreciation rate, r = 7%

The value of the car is then calculated as:

V = a * (1 -r)^t

Substitute known values

V = 27000 * (1 - 7%)^t

Evaluate the difference

V = 27000 * (0.93)^t

Hence, the exponential function models the value v of the car after t years is V = 27000 * (0.93)^t
