Quadrilateral CDEF is dilated by a scale factor of į to form quadrilateral C'D'E'F'.

Kobotan [32]

Given:

CDEF is dilated by a scale factor of $\dfrac{3}{4}$ to form the quadrilateral C'D'E'F'.

To find:

The measure of side E'F'.

Solution:

If a figure is dilated by a scale factor of k, then the side of dilated figure is k times of corresponding side of original figure.

CDEF is dilated by a scale factor of $\dfrac{3}{4}$ to form the quadrilateral C'D'E'F'. So,

$E'F'=\dfrac{3}{4}\times EF$

From the given figure it is clear that $EF=12$ . So,

$E'F'=\dfrac{3}{4}\times 12$

$E'F'=9$

Therefore, the measure of side E'F' is 9 units.

Daniel is using logarithms to solve the equation 2^4x = 14. Which of the following equations would be equivalent to his original

ycow [4]

Remember
$log_a(b^c)=(c)log_a(b)$
so
$2^{4x}=14$ take the log of both sides
$log(2^{4x})=log(14)$ or
$4xlog(2)=log(14)$

B is the answer
