Answer:
x = 0.343
Step-by-step explanation:
We want to solve:
5 - 3tan(3x) = 0
such that:
-π< x < π
where π = 3.14
then:
-3.14 < x < 3.14
Let's solve the equation:
5 - 3tan(3x) = 0
-3tan(3x) = -5
tan(3x) = -5/-3 = 5/3
Now we can use the inverse tan function, Atan(x).
Remember that:
Atan( tan(x) ) = tan( Atan(x)) = x
Then if we apply that function to both sides, we get:
Atan( tan(3x)) = Atan(5/3)
3x = Atan(5/3)
x = Atan(5/3)/3 = 0.343
X will be ur domain...and it represents time in hrs.....therefore, it cannot be a negative number...so that eliminates B and C. I do not believe it has to be a whole number...so I am going with A

Answer:
x = 2
Step-by-step explanation:
Using the scale factor, we have ...
x/8 = 0.25/1
x = 8(0.25) . . . . multiply by 8
x = 2

<em>Additional comment</em>
I like to write proportions with the variable in the numerator. That way they are easily solved by a single multiplication. The trick is to get corresponding parts in the same positions. Here, the fractions are written ...
B/A = smaller part / larger part = x/8 = 0.25/1
Based on the function given, the domain of f(x) is -18 ≤ x ≤ 10 and the range is 16 ≤ f(x) ≤ 95
<h3>What are the domain and range?</h3>
The domain of a function is found by looking at a graph from left to right. This means that x will be equal to or greater than the smallest x value and less than or equal to the largest x value.
Domain is therefore:
-18 ≤ x ≤ 10
The range can be found by looking at the y value. The value if f(x) will be equal to or greater than the smallest y value and less than or equal to the largest y value.
Range is:
16 ≤ f(x) ≤ 95

Answer:
Correct choice is 3rd choice
Step-by-step explanation:
Congruent circles must have congruent radii.
There are four circles with radii of 3 in, 4 in, 5 in and 3 in.
Hence, the first circle is congruent to the last circle, or circle A is congruent to the circle D.
