Cotangent is the inverse of tangent function. Hence, in this case, the equation is converted to tan 3x = -1/ squareroot 3 / 3 = -squareroot 3using a calculator in the radians mode,  3x is equal to -pi/3. This means x should be equal to -pi/18.

katovenus [111]

Answer:In this question, we're trying to find how many apples Jenson picked from the basket.

Lets gather information that can help us.

Important information:

Picked a fruit from a basket 40 times

Probability of picking an apple is 0.3

With the information above, we can solve the question.

We know that he picked up a fruit 40 times, but we need to find how many apples he picked up during the 40 times.

The probability of picking an apple is 0.3, which is equivalent to 30%

This means that 30% of the 40 times he picked an apple.

We would multiply 40 by 0.3 to get our answer.

This means that Jenson picked 12 apples.

I hope this helped you out.

Good luck on your academics.

Have a fantastic day!

3400 dollars is placed in an account with an annual interest rate of 8. 25%. How much will be in the account after 25 years, to
OLEGan [10]

The final amount in the account after 25 years is $24670.42.

<h3>How do you calculate the final Amount after 25 Years?</h3>

Given that 3400 dollars are placed in an account with an annual interest rate of 8.25% for 25 years.

The final amount in the account is calculated by the formula given below.

A = P ( 1 + \dfrac {R}{100})^T

Where A is the final amount, P is the initial principal balance, R is the interest rate, T is the time period.

The final amount is given below.

A = 3400 ( 1 + \dfrac {8.25}{100})^{25}

A = 3400 (7.256005874)

A = 24670.41997= 24570.42

Hence we can conclude that the final amount in the account after 25 years is $24670.42.
