Answer:
we have a right triangle and to get the internal angle of the right triangle formed at the helicopter we subtract 62 degrees from 90 which equals 28 degrees
we now use the cosine to find the distance (d) from the helicopter
cosine 28 = 85/d
d = 85 / cosine 28 = 85 / 0.8829 = 96.2736 = 96 feet
The answer is 2.76 because u round it 2 places to the right
Answer:
3
- 48
Step-by-step explanation:
Given
(a + 2)(3a² + 12)(a - 2)
= (a + 2)(a - 2)(3a² + 12) ← expand the first pair of parenthesis using FOIL
=(a² - 4)(3a² + 12) ← expand using FOIL
= 3 + 12a² - 12a² - 48 ← collect like terms
= 3 - 48
To solve this, you already have the y value of the coordinate, which is 3, and the x value is represented by a. Plug the values into your graph equation so that it looks like this: 3=2a-5
Then, add 5 to both sides to isolate 2a:
8=2a
Finally, divide both sides by 2 to get that a=4
Hope this helps!
