Answer:
D
Step-by-step explanation:
the three main trig functions are
sin = opposite / hypotenuse
cos = adjacent / hypotenuse
tan = opposite / adjacent
( opposite = side opposite of angle , hypotenuse = longest side and adjacent = other side )
Sin(55) = a/c as side a is opposite of the angle and c is the hypotenuse so D might be the answer
cos(55) would be b/c as the adjacent of that angle is b and the hypotenuse is c. B and C show the wrong ratios so B and C can't be the answer
tan(55) would be a/b as side a is opposite of the angle and b is the adjacent, A says c/a which is wrong
so we can conclude the answer is D
Using simple interest, it is found that the monthly payments are of $854.875.
<h3>Simple Interest</h3>
Simple interest is used when there is a single compounding per time period.
The amount of money after t years in is modeled by:

In which:
- A(0) is the initial amount.
- r is the interest rate, as a decimal.
In this problem, the parameters are A(0) = 49000, r = 0.0665, t = 7, hence the total amount is of:

![A(t) = 49000[1 + 0.0665(7)]](https://tex.z-dn.net/?f=A%28t%29%20%3D%2049000%5B1%20%2B%200.0665%287%29%5D)

Payments over a period of 12 x 7 = 84 months, hence the monthly payments are of:
71809.5/84 = $854.875.

Answer: aₙ = 3 + 4ⁿ⁻¹
So the formula would be:
<u>aₙ = 3 + 4ⁿ⁻¹</u>
Where a₁ = 3
Common Ratio (r) = 4
And n = the term number that needs to be found out
Step-by-step explanation:
<u>Let's check if the answer is right:</u>
To find the 1st number in the term we can substitute 1 in for n in the equation:
a₁ = 3 + 4¹⁻¹
a₁ = 3 + 4⁰
a₁ = 3 + 1
a₁ = 4
And if going back and checking the first number in the sequence given is indeed 4, therefore this equation is correct

The probability is just 1/2 that the disc will result with the white side landing up.
There are two sides to the disc. If they are equally likely to happen, then the chance of either side is 1/2. It does not matter which number the flip is.
