In money in a savings account earned 8.5% intrest per annum, how much interest would be earned on $200.00 over two years?

Reil [10]

Answer:

$1305.91

Step-by-step explanation:

To solve this, we can use the geometric sequence formula

$\alpha _n=a_1*r^n^-^1$

If we plug in our values we get $\alpha _n=200*1.085^2^3$

Thus, leaving us with 1305.91

Hope this helps

If the simple interest on $3,000 for 8 years is $1,200, then what is the interest rate?

Usimov [2.4K]

Answer:

i THINK its 18.75% per year

Step-by-step explanation:

r = (1/8)((3,000/1200) - 1 ) = 0.1875

r = 0.1875 * 100 = 18.75

(dont take my word tho, u should double check yourself)

What is the slope of this line?

zubka84 [21]

Answer:

3/2

Step-by-step explanation:

We can find the slope of this line by using two points

(1,-3) and (3,0)

m = (y2-y1)/(x2-x1)

= (0- -3)/(3 -1)

= (0+3)/(3-1)

= 3/2

A catering service offers 7 appetizers, 3 main courses, and 5 desserts. A customer is to select 4 appetizers, 2 main courses, an

algol13

This question is based on combinations

Out of 7 appetizers, 4 are to be selected, this becomes = 7C4

Out of 3 main courses, 2 are to be selected , this is = 3C2

Out of 5 desserts, 4 are to be selected, this is = 5C4

So, total ways become =

7C4 * 3C2 * 5C4

7!/4!(7-4)! * 3!/2!(3-2)! * 5!/4!(5-4)!

= 35*3*5 =525 ways

Hence, this can be done in 525 ways.

Suppose the population of a town is 2,700 and is growing 4% each year. A. Write an equation to model the population growth. B. P

miss Akunina [59]

Answer:

Third option i.e. A. $2700(1.04)^x$ and B. About 4,323 people

Step-by-step explanation:

We are given that,

Initial population of the town = 2,700

The rate of growth = 4% = 0.04

Part A: Since, the equation for the growth is given by,

Population growth = $P(1+r)^x$ , where P is the initial population, r is the rate of growth and x is the time period of growth.

We have, according to the question,

Population growth = $2700(1+0.04)^x$

i.e. Population growth = $2700(1.04)^x$

Thus, the equation for the population growth is $2700(1.04)^x$ .

Part B: Now, it is required to find the population after 12 years i.e. x= 12.

So, we have,

Population = $2700(1.04)^x$

i.e. Population = $2700(1.04)^{12}$

i.e. Population = $2700\times 1.601032$

i.e. Population = 4,323

Hence, the population after 12 years is 4,323 people.

Thus, the third option is correct.
