Answer:
The correct answer is A.
Step-by-step explanation:
The rule with a function is every input has exactly one output. In the answer choices b, c, and d all of them has a repeating input or x value.
17 pounds equals 7711.07 grams a day
Answer:
Step-by-step explanation:
≥ - 2
x - 4 ≥ - 6
x ≥ - 2
<em>x ∈ [ - 2 , ∞ )</em>
2 - 6x < 32
- 6x < 30
x > - 5
<em>x ∈ ( - 5 , ∞ )</em>
The problem says that <span>Brandon sights a helicopter above a building that is 200 feet away at an angle of elevation of 30 degrees. So, you can calculate the height asked, by following this procedure:
</span>
Tan(α)=Opposite leg/Adjacent leg
α=30°
Opposite leg=x
Adjacent leg=200 feet
When you substitute these values into the formula above (Tan(α)=Opposite leg/Adjacent leg), you have:
Tan(α)=Opposite leg/Adjacent leg
Tan(30°)=x/200
You must clear "x":
x=200xTan(30°)
Therefore, the value of "x" is:
x=115 feet
<span>
How high above the ground the is the helicopter?
The answer is: 115 feet</span>
You only need two numbers to do that.
The numbers are 16 and -3 .
16 - 3 = 13
(16) x (-3) = -48
