Well
You take the thing
You make sure a very good amount of light is pointing at the microscope
And then you turn the zoom-in or zoom-out
Answer:
4x² + 4x - 2
Step-by-step explanation:
The opposite is the negative value
The opposite of - 4x² - 4x + 2 is
- (- 4x² - 4x + 2) ← distribute parenthesis by - 1
= 4x² + 4x - 2
XY = xZ
85b + 83 = 91b - 283
Subtract 85b from both sides:
83 = 6b - 283
Add 283 to both sides:
6b = 366
Divide both sides by 6:
B = 61
Now replace b with 61 and solve for the length:
85(61) + 83
5185 + 83 = 5268
The length is 5,268

P=2L+2W
We know that L=26, W=21
so
Perimeter, P = 2(26)+2(21) = 52 + 42 = 94 feet
answer:
<h2>F2= 5kN</h2>
step by step explanation
<em>Note the second diameter was used as 50cm and not 500cm</em>
given
F1=800N
D1=20cm
A1=πD1^2/4
=3.142*20^2/4
=314.2cm^2
D2= 50cm
A2=πD2^2/4
=3.142*50^2/4
=1963.75cm^2
The pressure applied on the smaller relative to the bigger end is expressed as
F1/A1=F2/A2
substitute we have
800/314.2=F2/1963.75
cross multiply we have
F2=800*1963.75/314.2
F2=1571000/314.2
F2=5000N
F2=5kN
The larger Force is 5kN
