Answer:
Step-by-step explanation:
This is even because if we put x=1 then we get 10 if we put x=2 then we get 20 and so on. So all these are even numbers.
Answer:
x ≈ 14.57
Step-by-step explanation:
using the sine ratio in the right triangle
sin59° =
=
( multiply both sides by 17 )
17 × sin59° = x , then
x ≈ 14.57 ( to 2 dec. places )
Answer:
The graph of y=5 is a horizontal line. The point (-4, 5) lies on the lines.
Step-by-step explanation:
This is horizontal because 5 on the y axis is always going to stay the same. For any x value, the y value is 5. Therefore, (-4, 5) is part of that line.
Answer:
Since the value of f(0) is negative and the value of f(1) is positive, then there is at least one value of x between 0 and 1 for which f(x) =0.
Step-by-step explanation:
The equation f(x) given is:

For x = 0. the value of the expression is:

For x = 1, the value of the expression is:

Since the value of f(0) is negative and the value of f(1) is positive, then there is at least one value of x between 0 and 1 for which f(x) =0.
In other words, there is at least one solution for the equation between x=0 and x=1.
