Answer:

2/5

Step-by-step explanation:

First, we need to find the slope of line a. To do this, we subtract the two y values and then the two x values and divide these two differences.

10-5=5

6-8=-2

5/-2= -5/2

A perpendicular line's slope will always be equal to the negative reciprocal of the intersects. So, we just flip the numerator and denominator and then add a negative to our first slope to get the slope of line b.

-2/5

--2/5

2/5

Have a wonderful day! :D

Ill give all my points to someone who can solve this probability problem correctly and clearly to understand.
Mashutka [201]

Answer:

+5.20 µC

Explanation:

Given that

Charge =−5.20 µC and radius= 5.40 cm.

Insert a +10.4- µC charge at the center of the sphere

As we know that according to  Gauss's theorem electric field inside the metal is zero.

When +10.4 µC charge insert but the total charge on the sphere should be  −5.20 µC.So the charge on the outer surface of the sphere will be +5.20 µC.

In Mr. Romano’s class, 40% of the students like baseball. If 14 of his students like baseball, how many students are in Mr. Roma
enyata [817]

Answer:

35 Students

Step-by-step explanation:

So if 40% of the students like Baseball and that there are 14 students in the class room.

Another way to interpret this is that you can divide 14 by 40% to find the total amount.

This gets you: 14 divided by 0.40 = 35 Students
