Answer:
The answer would be 3216.
Step-by-step explanation:
You subtract 400 from 3600 to get 3200. You add 16+ to the answer. Then you get 3216. Voila.
Answer: it will have three terms. It will be in the form ax^2 + bx + c
The "a" could be any number, but if it is "1", it will be left out.
The "+" sign is often a minus sign.
^2 means "squared" and is usually shown as an exponent, but my keyboard don't have that capability now.
Examples
x^2 + 5x +4
5x^2 +13x -6
2x^2 -11x + 15
Answer:
Step-by-step explanation:
Given that:
The focal point = 18 inches
= (18 × 0.0254)m
= 0.4572 m
= 45.7 cm
For such a comfortable distance of 45.7 cm, the perfect lens power for grandfather can be determined.
Let's recall that, the accommodation amplitude usually decreases with age and eventually becomes 1 D after the age of 50.
Thus, +2.5D or a convex lens appears to be a perfect one.
b. We will agree that Diopter illustrates the optical power or most at times the capability of the lens.
So, 3D is equally 1.75X magnification which is likely to be double the zoom as it will be helpful to the grandfather.
Now, for a 2.5D, approximately 1.5X zooming once(200%) will be perfect and equal to viewing with the reading glasses.
Answer:
Exponential Growth, 1200(1.15)
Step-by-step explanation:
It is a Growth function because it is "increasing" yearly. The equation is multiplying with 1.15 because when it is increasing, you need to add 1 to the percentage rate.
