The rate is 0.30 km/min. The rate in linear functions, which must be assumed with only two given points can be traced to calculating the slope (m) of the line or rate.
m= (y2-y1) / (x2-x1)
with our two given points (x,y) we fill out the equation as:
M= (12 - 0) / (40 - 0) or M = 12/40 = 0.3
keeping our units intact 12 km / 40 min so the answer is 0.3 km/min
The answer is 6:2. Since the greatest common denominator of both is 2 you divide it by both numbers to get the ratio.
Answer: f(t) = 15 - 1.1t
Step-by-step explanation:
Let t represent the number of hours since the candle was lit.
A 15-inch candle is lit and burns at a constant rate of 1.1 inches per hour. This means that in t hours, the candle that would have burnt is 1.1t
The length of the candle that would be left after t hours is expressed as
15 - 1.1t
suppose f is a function such that f(t) represents the remaining length of the candle (in inches) t hours after it was lit, then
f(t) = 15 - 1.1t
Answer:
2 miles in 8 minutes
4 miles in 16 minutes
8 miles in 32 minutes
16 miles in 64 minutes
Step-by-step explanation:
Answer:
x = 11.7
Step-by-step explanation:
3(x + 3) = 4(4 + 7) => intersecting secant theorem
3(x + 3) = 4(11)
3x + 9 = 44
3x + 9 - 9 = 44 - 9
3x = 35
x = 11.7
