If 3n + 2 = 14, what must 3n be equal to?

Answers


If 3n + 2 = 14, then

3n + 2 – 2 = 14 – 2


3n = 12    <———    this is the answer.

What must be added to
2x² - 3 xy + 5yz to get x² - xy + y²​

Answers

Answer:

  • -x² + y² + 2xy - 5yz

Step-by-step explanation:

"A" must be added to  first expression to get the second one:

  • A + 2x² - 3 xy + 5yz =  x² - xy + y²​
  • A = ?

------------------------

  • A = x² - xy + y²​ - (2x² - 3 xy + 5yz) =
  • x² - xy + y²​ - 2x² + 3 xy - 5yz=
  • -x² + y² + 2xy - 5yz

Find b, given that a = 20, angle A = 30°, and angle B = 45° in triangle ABC

Answers

Answer:

b = 20√2

Step-by-step explanation:

Given: ΔABC

           a = 20 , m∠A =  30° and m∠B = 45°

To find: value of b.

We use Sine result, which state that

(a)/(sin\,A)=(b)/(sin\,B)

Substituting given values we, get

(20)/(sin\,30^(\circ))=(b)/(sin\,45^(\circ))

we know thatsin\,30^(\circ)=(1)/(2)\:and\:sin\,45^(\circ)=(1)/(√(2)), we get

(20)/((1)/(2))=(b)/((1)/(√(2)))

20{*2}=b*√(2)

b*√(2)=40

b=(40)/(√(2))

b=20√(2)

Therefore, b = 20√2

The side b is opposite to the angle B, applying the law of the sines, we have:

(a)/(sinA) = (b)/(sinB)
(20)/(sin30^0) = (b)/(sin45^0)
(20)/( (1)/(2) ) = (b)/( ( √(2) )/(2) )
20* ( √(2) )/(2) = b* (1)/(2)
(20 √(2) )/(2) = (b)/(2)
2*b =2*20 √(2)
2b = 40 √(2)
b = (40 √(2) )/(2)
\boxed{b = 20 √(2) }

Two angles in a triangle add up to 85 degrees what is the size of the third angle

Answers

all of the angles in a triangle should add up to 180 degrees so if you know 2 out of three you just do subtract 180 by the sum of the two angles.
180-85=95

Consider the function y = 1.065(4), which represents thegrowth of capital in a bank account.

The annual interest is

___%, and the bank compounds the interest_____

The balance of the account will

grow____

Answers

The annual interest rate is 6.5%, and the bank compounds the interest annually. The balance of the account will grow exponentially over time.

The given function y = 1.065(4) represents the growth of capital in a bank account, where the initial balance is 4 and the growth rate is 6.5% per year. To calculate the annual interest rate, we can use the formula A = P(1 + r/n)^(nt), where A is the final amount, P is the initial principal, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the time in years.

In this case, the final amount after one year is 4 * 1.065 = 4.26. Substituting the values in the formula, we get 4.26 = 4(1 + r/1)^(1), which simplifies to 1 + r = 1.065. Solving for r, we get r = 0.065 or 6.5%.

The bank compounds the interest annually, which means that the interest is added to the account balance at the end of each year. As the balance grows, the interest earned in the subsequent years will be higher. This results in exponential growth of the account balance over time. After n years, the account balance will be B = P(1 + r)^n, where P is the initial balance, r is the annual interest rate, and n is the number of years.

For example, after 5 years, the account balance will be B = 4(1 + 0.065)^5 = 5.39. After 10 years, the account balance will be B = 4(1 + 0.065)^10 = 7.27. As we can see, the account balance grows significantly over time due to the effect of compounding interest.
