Answer:
log₂(3) = 1.585 ≠ 1.5
Her thinking is not valid because the technique of average is valid only if the graph of the function is a straight line, but the graph of the log function is not a straight line.
Therefore the values cannot be taken by average
Step-by-step explanation:
Given:
log₂(2) = 1
log₂(4) = 2
To evaluate : log₂(3)
Now,
we know that
logₓ(y) = (Here the log has same base in the numerator and the denominator i.e 10)
therefore,
log₂(3) =
also,
log(2) = 0.3010
log(3) = 0.4771
thus,
log₂(3) =
or
log₂(3) = 1.585 ≠ 1.5

Answer:
A
Step-by-step explanation:
The line from the vertex to the base is a perpendicular bisector and divides the isosceles triangle into 2 right triangles.
Using Pythagoras' identity in either of the 2 right triangles, then
( x )² + 3² = (
)²
x² + 9 = 45 ( subtract 9 from both sides )
x² = 36 ( multiply both sides by 4 to clear the fraction )
x² = 144 ( take the square root of both sides )
x = = 12 → A
