i think the best answer for this question is A)
Answer:
Step-by-step explanation:
√14 cannot be rewritten as the ratio of two integers and thus is irrational.
Similarly, √99 is irrational; √99 = √9√11 is irrational even though √9 is not.
Answer:
The ray that goes parallel to the main axis after passing through the lens should also be parallel from the object to the lens
Step-by-step explanation:
To form the image of an object using a convex lens, ray diagrams are used. The following steps are followed when drawing ray diagrams.
1) Light rays are drawn from the object incidented on the lens and parallel to the principal axis. The incident light refracts (bends) through the lens and converges at the focal point at the other side of the lens.
2) Another incident light passes through the optical centre undeflected and intersect with the refracted ray at the other side of the lens.
Based on the above points, Roshan made an error by drawing the ray that goes parallel to the main axis and after passing through the lens made the same ray to be parallel from the object to the lens instead of refracting (bending) after passing through the lens.
What is the value of X?
Simplify:
8x - 10 - 4x = - 12(12x - 20)
Simplify both sides:
8x - 10 - 4x = - 12(12x -20)
8x + - 10 + - 4x = (- 12)(12x) + ( -12)(- 20)
(Distribute:)
8x + - 10 + - 4x = 144x 240
(8x + - 4x) + ( -10) = - 144x + 240 (Combine Like Terms:)
4x + - 10 = - 144x + 240
4x - 10 = - 144x + 240
Add - 144x to both sides:
4x - 10 + 144x = - 144x + 240 + 144x
148x - 10 = 240
Add 10 to both sides:
148x - 10 + 10 = 240 + 10
148x = 250
Divide both sides by 148
148x/148 = 250/148
x = 125/74
Answer: x = 125/74 (Decimal: 1.689189)
