Answer:
y-int = (0, -6)
Step-by-step explanation:
The y-intercept is the b-value of the equation of the line y = mx+b
To find the y-intercept plug in 0 for the x-value:
y=3(0) - 6
y= -6
-> x = 0, y = -6
Answer:
r = 6.40 feet
Step-by-step explanation:
Given line AB is tangent to circle O at point A, this means ∡OAB = 90°
Hence this is a right angle triangle and we can use the Pythagorean theorem.
r² + 20² = 21²
r² = 21² - 20²
r² = 441 - 400
r² = 41
r = √41 = 6.40 feet
x is the number od doubling periods ( which is given as every 7 years)
28 years / 7 = 4 doubling periods in 28 years
so x = 4
so you now have:
f(x) = 8000 * 2^4
2^4 = 16
so 8000 * 16 = $128,000 would be the answer
