The value of cos A is √(1 + x²)/ (1 - x²) /√1 + x
<h3>Trigonometric ratios</h3>
It is important to note that
sin A = opposite/ hypotenuse
cos A = adjacent/ hypotenuse
Then,
opposite = 
Hypotenuse = 
Let's find the adjacent side using the Pythagorean theroem



cos A = x/hypotenuse

cos A = √(1 + x²)/ (1 - x²) /√1 + x
Thus, the value of cos A is √(1 + x²)/ (1 - x²) /√1 + x

Answer:
part A: Mean:6.42 Median:7
Part b: median
Part c: no it’s skewed left and unimodal
Step-by-step explanation:
(0,2),(-2,-1),(2,5)
-3x+2y=2
+3x +3x
2y/2=3x+2/2
y=1 1/2x+2
Plug in numbers for x then solve for y
Hi, thank you for posting your question here at Brainly.
To solve this, you have to know the conversion factors.
1 yard = 3 ft = 36 inches
Thus,
48 inches * (1 yard/36 inches) = 1.33 yards
This means that you need to buy at least 2 yards per bolt.
Answer:
35 < 56.
- <em>56 is greater than 35.</em>
