The correct option is C no, both 3.61^2 and 3,62^2 are greater than 13.
<h3>Is he correct? If not, what was his mistake?</h3>
To check this, we can just square both of the bounds that he found, and see if it makes sense.
Walter says hat:
3.61 < √13 < 3.62
Then we must have:
(3.61)^2 < 13 < (3.62)^2
The lower bound is 3.61, if we square it we get:
3.61*3.61 = (3 + 0.61)*(3 + 0.61) = 9 + 6*0.61 + 0.61*0.61 = 13.0321
Now, this is larger than 13, so the above inequality is false, which means that Walter is incorrect, because both 3.61 and 3.62 are larger than √13 , then the correct option is C.

7/8 + 1/4 * 5/6....no parenthesis means we do the multiplication first
7/8 + 5/24 =
21/24 + 5/24 =
26/24 which reduces to 13 / 12 or 1 1/12
Answer:
f^(-1)(x) = 4x + 48.
Step-by-step explanation:
Is suppose the function is f(x) = 1/4 x - 12
This is equivalent to the line y = 1/4 x - 12.
To get the inverse, change the x and y:
x = 1/4 y - 12
Now solve for y:
x + 12 = 1/4 y
y = 4x + 48
So the inverse f^(-1)(x) = 4x + 48.
Regular hexagons have all equal sides and angles
=((3cmx2.6)/2) x 6
=( 7.8/2) x6
= 3.9 x 6 The answer is B. 23.4cm
= 23.4
