Answer:
40 cm.
Step-by-step explanation:
Given,
height of the object = 10 cm
Distance of the object from the X-ray= 50 cm
Distance of detector from the source = 2 m = 200 cm
Height of the image, h = ?
Now,



Again applying


h = 40 cm
Hence, height of the image is equal to 40 cm.
I believe the answer would be 3/40
Answer:
B is 6.
Step-by-step explanation:
We are trying to find a value for
such that:
is true for every
.
So let's choose
:




Divide both sides by -8:



Note: I didn't want to choose y to be 0 because the value of B would disappear from the equation. So you should be able to have chosen any x and y except for y=0 to solve the equation for B.
Check:
So let's check and use foil to multiply out the right hand side.




There was a 2 in front of that multplicapltiation:



This is exactly what we have on the left hand side of your given equation.

➷ To find the mean you add together the values and divide by how many values there are:
150 + 100 + 120 + 200 + 180 + 300 + 250 = 1300
1300/7 = 185.714285
Median:
Order the values and find the middle one:
100, 120, 150, 180, 200, 250, 300
As you can see, it is 180
