Bradley is purchasing a new car for 37000. If the car loses 20%of its value every year, how much will the car be worth in 7 year
spayn [35]
ANSWER

After 7 years the car will worth, 7,759.5

EXPLANATION

The initial value of the car is 37000.

The rate of depreciation is 20%

In 7 years time, we can calculate the value of the car using the formula,

A=P(1-r\%)^n

We substitute the values into the formula to obtain,

A=37000(1-0.2)^7

A=37000(0.88)^7

A=7759.5 to the nearest tenth

In a recent year, the population of California was about 2.52 x 10^7 people. Its land area is about 4.05 x 10^5 km^2. What was t
andrezito [222]

The population of California = 2.52 \times 10^7 people.

Land area of California = 4.05 \times 10^5km^2.

We have to determine the average number of people per square kilometer.

Average number of people per square kilometer =

Land area of California \div Population of California

= 4.05 \times 10^5 \div 2.52 \times 10^7

= 1.6 \times 10^{-2}

Therefore, the average number of people per square kilometer is  1.6 \times 10^{-2}.

It is represented in scientific notation as Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.

The last term of an arithmetic sequence is 14 and the ninth term is -1. Find the first four
Olegator [25]

Answer:

13

Step-by-step explanation:

where n is the number of terms, a1 is the first term and an is the last term. The sum of the first n terms of an arithmetic sequence is called an arithmetic series . Example 1: Find the sum of the first 20 terms of the arithmetic series if a1=5 and a20=62 .An arithmetic sequence is a sequence where the difference between any two consecutive terms is a constant. ... As with any recursive formula, the initial term of the sequence must be given. An explicit formula for an arithmetic sequence with common difference d is given by an=a1+d(n−1) a n = a 1 + d ( n − 1 ) .
