Answer:

the opposite positive number is negative, and the opposite to a negative number is positive.

Step-by-step explanation:

In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite number, sign change, and negation. For a real number, it reverses its sign: the opposite to a positive number is negative, and the opposite to a negative number is positive.

<h3>What is simple interest?</h3>

Simple interest is calculated based on a loan's principal or the initial deposit into a savings account. Simple interest doesn't compound, so a borrower will never have to pay interest on the interest already accumulated because a creditor will only pay interest on the principal amount.

Formula for simple interest is;-

Simple interest = (principal amount×rate of interest×time duration in years)/100

S.I = (P×R×T)/100

Calculation of the total amount paid by Ted to the bank-

The principal amount is $5,600.

The rate of interest is 9%.

Time duration is 4 months equals 4/12 = 1/3 years.

S.I = (5,600×9×1)/(3×100)

S.I = 168

The simple interest on amount is $168.

Thus, the total amount is S.I + principal amount

Total amount = 168 + 5600

= 5768

Therefore, the total amount paid by the Ted to the bank is $5768.

i need to find the measure of angle b in a right triangle... the base is 4. they hypotenuse is 9 and angle c is the right angle.

Romashka [77]

One way to solve this question is through trigonometry. :)

If you've learnt trigonometry, here are the basic formulas:
SOH CAH TOA (These formulas only apply for right-angled triangles)

Sin(angle) = (Side that is Opposite of angle)/(Hypotenuse)

Cos(angle) = (Side that is Adjacent of angle)/(Hypotenuse)

Tan(angle) = (Side that is Opposite of angle)/(Side that is Adjacent of angle)

In this case, we should use sine of b (the angle at the top of triangle as indicated in your question), where the opposite side is the base (I.e. 4 indicated in your question) and the hypotenuse is 9.

sin(b) = 4/9
{Make angle b the subject of the equation}
$b = {sin}^{ - 1} ( \frac{4}{9} )$
{Type this into the calculator}
Angle b = 26.4° (rounded off to 1 decimal place)

Hope this helps! :)
