Answer: 105 grams
Step-by-step equation: they each eat 21 grams a day
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>
Answer:
B. 2 in.
Step-by-step explanation:
First, put the two perimeters together to form a fraction.
192/48, which can simplify to 4/1
Now, following the order in which you put the perimeters (I used C/D,) set it equal to the sides.

Now, cross multiply. (multiply 1 and 8, 4 and x.)

Now, solve.
x=2 inches.
Answer:
The function which represents this sequence will be:

Hence, option (A) is true.
Step-by-step explanation:
Given the sequence

An arithmetic sequence has a constant difference 'd' and is defined by

computing the differences of all the adjacent terms

As the difference is the same, so

as

Thus, substituting
,
in the nth term of an arithmetic sequence



Therefore, the function which represents this sequence will be:

Hence, option (A) is true.
