Answer: see below
<u>Step-by-step explanation:</u>
The coordinates on the Unit Circle are (cos, sin). Since we are focused on cosine, we only need to focus on the left side of the coordinate. The cosine value (left side) will be the y-value of the function y = cos x
Use the quadrangles (angles on the axes) to represent the x-values of the function y = cos x.
Quadrangles are: 0°, 90°, 180°, 270°, 360° <em>(360° = 0°)</em>
Together, the coordinates will be as follow:
Answer:
$146410
Step-by-step explanation:
The formula for calculating future value:
FV = P (1 + r)^n
FV = Future value
P = Present value
R = interest rate
N = number of years
100,000 x (1.1)^4 = $146410
Answer:
The length of the ramp is 13 ft according to the Pythagorean theorem but I don't have an idea about the angle incline.. we must trigonometry to find it .
First you divide $4000 by 160 to see how much each book costs. Then you multiply 2 times the cost for each book and subtract that from $4000.
$4000/160= $25
$25=1 book
So if the store gives away 2 books that's $50 dollars. $4000-$50 equals 3,950
Answer:
Below in BOLD.
Step-by-step explanation:
1. x^2 = 3^2 + 6^2
x^2 = 9 + 36 = 45
x = √45
x = 3√5.
2. 15^2 = x^2 + 12^2
x^2 = 15^2 - 12^2 = 225 - 144 = 81
x = 9.
9, 10 and 15 are Pythagorean triplets.
3. x^2 = 10^2 - 6^2 = 64
x = 8.
6, 8 and 10 are Pythagorean triplets.
