Answer:

The compound interest formua is used to figure out how much interest will be paid on a loan or on an investment.

Step-by-step explanation:

P is Principal, the original amount of the loan or investment.

R is the rate, the percentage of interest charged, changed to a decimal.

T is Time, usually the number of years.

N is the number of times the interest is compounded, like 12 times in a year or 365 times per year for some credit cards.

A man flies a kite at a height of 16 ft. The wind is carrying the kite horizontally from the man at a rate of 5 ft./s. How fast

Talja [164]

Answer:

4.41 feet per second.

Step-by-step explanation:

Please find the attachment.

We have been given that a man flies a kite at a height of 16 ft. The wind is carrying the kite horizontally from the man at a rate of 5 ft./s. We are asked to find how fast must he let out the string when the kite is flying on 34 ft. of string.

We will use Pythagoras theorem to solve for the length of side x as:

$x^2+16^2=34^2$

$x^2=34^2-16^2$

$x^2=900\\\\x=30$

Now, we will use Pythagorean theorem to relate x and y because we know that the vertical side (16) is always constant.

$x^2+16^2=y^2$

Let us find derivative of our equation with respect to time (t) using power rule and chain rule as:

$2x\cdot \frac{dx}{dt}+0=2y\cdot \frac{dy}{dt}$

We have been given that $\frac{dx}{dt}=5$ , $y=34$ and $x=30$ .

$2(30)\cdot 5=2(34)\cdot \frac{dy}{dt}$

$300=68\cdot \frac{dy}{dt}$

$\frac{dy}{dt}=\frac{300}{68}$

$\frac{dy}{dt}=4.4117647058823529$

$\frac{dy}{dt}\approx 4.41$

Therefore, the man must let out the string at a rate of 4.41 feet per second.

Forty percent of all high school graduate work during the summer to earn money for college tuition for the upcoming fall term. A

Travka [436]

Answer:

$0.0467$ is the probability that none of the graduates have a summer job

Step-by-step explanation:

Here

P $= 0.40$ and n $= 6$

Probability that none of the graduate gets job

this means that x = 0

P (x = 0) $= ^6C_0 * (0.40)^0 * (0.60)^6$

P (x = 0) $= 0.0467$
