Answer:
A = 1
B = 2
C = below
Step-by-step explanation:
Zero is included in the second interval, therefore, A = 1 is a correct choice (A must be also less than 2 ).
B must be positive, so that, f(0) is above the x-axis, therefore, B = 2 is a correct choice.
f(1.5) is negative, this means that the function is <u>below</u> the x-axis, then, C = below.
Answer:
44 m/h
Step-by-step explanation:
speed/how fast = distance ÷ time
= 308 miles ÷ 7 hours
= 44m/h
we know that
the standard form of the equation of the circle is
where
(h,k) is the center of the circle
r is the radius of the circle
In this problem we have
<u>Convert to standard form</u>
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square twice. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
the center of the circle is 
the radius of the circle is 
therefore
<u>the answer is</u>
the radius of the circle is
Answer:
the factors of 42 in pairs are (1, 42), (2, 21), (3, 14) and (6, 7).
Step-by-step explanation:
May I get brainelist?
According to the problem, y = f(x) = 2x
Here the value of x = 2.
We have to put the value of x in place of x in 2x to calculate the actual value of 2x.
Therefore, after putting the value of x in 2x we get 2x = 2 x 2 = 4
This means the value of 2x is 4. This is because we have included the given value of x to get the value of 2x.
Again the value of f(x) = 2x.
Therefore, the value of f(x) = 2x = 4.
