Answer:
x = 17
Step-by-step explanation:
in such a constellation (two beams from the same point of origin cut through the same circle) the relative relation between the segments of these beams to the overall length of the beam have to be the same :
7 × (7+x) = 8 × (8+13)
49 + 7x = 8 × 21 = 168
7x = 119
x = 17

That’s nice to know i guess? i don’t know where you’re trying to go with this-
Answer:
A
Step-by-step explanation:
A linear function increases/decreases by a certain amount every year. As it changes 1500 over the first 5 years (300 per year) and 3000 over the next 5 (600 per year), this cannot be liner
A quadratic function goes down then up, or vice versa. This consistently goes up, and is therefore not quadratic
A trigonometric function also goes up and down, so it is not trigonometric
Therefore, as an exponential function can keep going up at different rates over time, this is an exponential function
