Answer: The answer would be the one going a slope downwards
Step-by-step explanation:
Answer:
I(7) = 22.96 W/m²
Step-by-step explanation:
Let intensity of light, be I(d) where d is distance. There must be a proportionality factor K such as
I(d) = K /d²
Now for d = 5 m I(d) = K* 1/d²
then 45 * 25 = K
K = 1125
To find the intensity when the distance from the light bulb is 7 m away
I(7) = K / 49
I(7) = 1125/49 W/m²
I(7) = 22.96 W/m²
Answer:
C
Step-by-step explanation:
Using the explicit formula, then
a₅ = 50 × 
= 50 × 16 = 800 → C
The approximate value of the function at x=-4 according to the function is B)1.8
