1 answer:
Answer:
Step-by-step explanation:
The area of a parallelogram is A=bh.
From the diagram, the base is b=5m
We now use the properties of 30°-60°-90° right angle to find h.
The sides of this triangle is given by x,½x,½x√3
Where x is 4
Therefore we have 4,2, 2√3
So we have h=2√3m
The area now is

Answer:
.
In other words, the in
could be any real number as long as
for all integer
(including negative integers.)
Step-by-step explanation:
The tangent function has a real value for real inputs
as long as the input
for all integer
.
Hence, the domain of the original tangent function is .
On the other hand, in the function , the input to the tangent function is replaced with
.
The transformed tangent function would have a real value as long as its input
ensures that
for all integer
.
In other words, would have a real value as long as
.
Accordingly, the domain of would be
.
Answer: He is not correct.
Steps:
Let x1 and x2 be the first and second number, respectively.
In words, if the second is 125%, or 5/4 of the first number (first equation),
then the first is 4/5 of the second, which is 0.8 or 80%.
