Answer:
x>-7
Step-by-step explanation:
A
X intercept is where x=0
y intercept is where y=0
Answer:
-3x+6
Step-by-step explanation:
Again, you multiply -3 times x and you get -3x, then you multiply -3 times -6 and since you are multiplying two negative numbers the result becomes positive so you get +6. Result = -3x+6
The correct answer to this question will be the yellow box which is <5 less than five
Answer:
John ski down the mountain is 1285.37 feet.
Step-by-step explanation:
Given : John is skiing on a mountain with an altitude of 1200 feet. The angle of depression is 21.
To find : About how far does John ski down the mountain ?
Solution :
We draw a rough image of the question for easier understanding.
Refer the attached figure below.
According to question,
Let AB be the height of mountain i.e. AB=1200 feet
The angle of depression is 21 i.e. ![\theta=21^\circ](https://tex.z-dn.net/?f=%5Ctheta%3D21%5E%5Ccirc)
We have to find how far does John ski down the mountain i.e. AC = ?
Using trigonometric,
![\cos\theta = \frac{AB}{AC}](https://tex.z-dn.net/?f=%5Ccos%5Ctheta%20%3D%20%5Cfrac%7BAB%7D%7BAC%7D)
![\cos(21)= \frac{1200}{AC}](https://tex.z-dn.net/?f=%5Ccos%2821%29%3D%20%5Cfrac%7B1200%7D%7BAC%7D)
![AC=\frac{1200}{\cos(21)}](https://tex.z-dn.net/?f=AC%3D%5Cfrac%7B1200%7D%7B%5Ccos%2821%29%7D)
![AC=1285.37](https://tex.z-dn.net/?f=AC%3D1285.37)
Therefore, John ski down the mountain is 1285.37 feet.
