Evaluate in 7.
a) .51
b) 1.95
c) .85
d) 1.95

The correct answer option is b) 1.95.

Step-by-step explanation:

We are to evaluate .

For this, we can either log in the value directly in a scientific calculator for the the given value and get the answer in decimals.

Another way can be to rewrite the expression as:

log to the base or = x

or

which gives x = 1.95

x + 4/7

step-by-step explanation:

use cymath

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
