Answer: x=52
Step-by-step explanation:
got it right on khan
we know that
The x-intercept is the value of the variable x when the value of the function is equal to zero
so
In the table we have
is a x-intercept, because
For the value of the function is equal to zero
is a x-intercept, because
For the value of the function is equal to zero
therefore
<u>the answer is</u>
the continuous function in the table has two x-intercepts
Answer:
4.5 meters
Step-by-step explanation:
6*.75=4.5
We need to multiply the 6 by 3/4 (.75) because it would be the same if it were 2 times as long, the only difference is that the answer will be smaller.
X=360, because cos ( 90 degrees ) =0
