She has 860 dollars after vacation
Answer:
I believe it is 3.75
Step-by-step explanation:
(5^49/5^48)+4^0−(1)^79⋅(−3/−4^9)^0
5+1−(1)^79⋅(−3/−4^9)^0
5+1−(1)^79
5⋅(−3/−4^9)^0
-3 divided by -4 to the power of 9 to the power of 0=0.75
5 times 0.75=3.75
Hope this is correct! xx
Rounded up to 0.4
ffffffffff
The slope of the red line that is perpendicular to the green line is: -5/2.
<h3>What are the Slope Values of Perpendicular Lines?</h3>
When one line lies perpendicular to another line, the slope of one must be the negative reciprocal of the other line.
<h3>What is the Negative Reciprocal of a Number?</h3>
If given a number, i.e. a/b, the negative reciprocal of a/b would the opposite value of the reciprocal of a/b.
Reciprocal of a/b is b/a. Negative reciprocal of a/b would therefore be: -b/a.
Given that the slope of the green line is: 2/5. And it is perpendicular to the red line. The slope of the red line would be the negative reciprocal of 2/5.
Negative reciprocal of 2/5 is -5/2.
Therefore, the slope of the red line is: -5/2.
