Answer:

The question is incomplete, the complete question is "Changing Bases to Evaluate Logarithms in Exercise, use the change-of-base formula and a calculator to evaluate the logarithm. See Example 9. $log_{4}7$ .

$log_{4}7=1.404\\$

Step-by-step explanation:

From the general properties or laws of logarithm, we have the

$log_{a}b=\frac{logb}{loga} \\$

where both log are now express in the natural logarithm base.

i.e $log_{a}b=\frac{lnb}{lna}\\$

hence we can express our $log_{4}7=\frac{ln7}{ln4} \\$ .

the value of ln7 is 1.9459 and ln4 is 1.3863

Hence $log_{4}7=\frac{ln7}{ln4}=\frac{1.9459}{1.3863}\\$ .

$log_{4}7=1.404\\$

Can u help? thank you.

Answer:

y = -1/2x +1/2

Step-by-step explanation:

Point B is 4 up and 2 over from point A. So, the midpoint will be 4/2 = 2 up and 2/2 = 1 over, at (1, 0).

The ratio of rise to run between A and B is ...

m = rise/run = 4/2 = 2

The perpendicular line will have a slope that is the opposite reciprocal of this, -1/2.

Then the point-slope equation for the perpendicular bisector is ...

y -k = m(x -h) . . . . . line with slope m through point (h, k)

y -0 = -1/2(x -1) . . . .line with slope -1/2 through point (1, 0)

y = -1/2x +1/2 . . . . simplified to slope-intercept form
