$8000 principal earning 5% compounded annually, after 6 years

Verdich [7]

Future amount after 6 years will be: $10720.76

Step-by-step explanation:

Principal = $8000

Interest= 5% compounded annually

Time = 6 years

We need to find A (future amount)

The formula used is:

$A=P(1+\frac{r}{n})^{nt}$

A= Future amount

P= Principal amount

r= interest rate

n= no of times interest is applied

t= time

Putting values and finding A

P=8000. r=0.05, n=1, t=6

$A=P(1+\frac{r}{n})^{nt}\\A=8000(1+\frac{0.05}{1})^{1*6}\\ A=8000(1+0.05)^{6}\\ A=8000(1.05)^{6}\\A=10720.76$

So, Future amount after 6 years will be: $10720.76

The value of a collector’s item is expected to increase exponentially each year. The item is purchased for $500. After 2 years,

Anika [276]

Answer:

Option 2 is correct.

Step-by-step explanation:

Actual price = $500

After 2 years the worth of item is increased to = $551.25

We need to find the equation that represents y, the value of the item after x years.

According to given information the equation can be of form

$y=500(r)^x$

where r represents the growth and x represents the number of yeras.

We need to find the value of r that represents the growth

The value of y = 551.25, and value of x = 2

Putting values and solving:

$y=500(r)^x\\551.25 = 500(r)^2\\551.25/500 =(r)^2\\1.1025 = (r)^2\\Taking square root on both sides\\\\\sqrt{1.1025}=\sqrt{(r)^2}\\ => (r) = 1.05\\$

Putting value of r in the equation

$y=500(r)^x$

$y=500(1.05)^x$

So Option 2 is correct.

The equation of a line is 5x − 3y = 6. Which is the y-intercept of the line?

oksian1 [2.3K]

Answer:

y - intercept. = 2.

Step-by-step explanation:

Given : The equation of a line is 5x − 3y = 6.

To find : Which is the y-intercept of the line.

Solution : We have given 5x − 3y = 6.

Equation of line y = mx +b

Where , m = slope , y intercept = b

Now we convert the 5x − 3y = 6 in line form y = mx +b

5x − 3y = 6

On subtracting both sides by 5x

-3x = - 5x + 6

On dividing both sides by - 3.

x = $\frac{5x}{3}+2$ .

We cans see m = $\frac{5}{3}$ , y - intercept. = 2.

Therefore, y - intercept. = 2.

A 25-foot ladder leans against a wall. The base of the ladder is 15 feet from the bottom of the wall. How far up the wall does t

motikmotik

Answer: 20 feet.

Step-by-step explanation:

Observe the right triangle attached.

You need to find the value of "x".

Then, you can use the Pythagorean Theorem:

$a^2=b^2+c^2$

Where "a" is the hypotenuse of the triangle, and "b" and "c" are the legs.

In this case, you can identify that:

$a=25ft\\b=15ft\\c=x$

Substitute these values into $a^2=b^2+c^2$ :

$(25ft)^2=(15ft)^2+x^2$

Now, you need to solve for x to find how far up the wall the top of the ladder reaches. Then you get:

$x^2=(25ft)^2-(15ft)^2$

$x=\sqrt{(25ft)^2-(15ft)^2}$

$x=20ft$
