Df/dy=(1350-750)/(2010-2000)
df/dy=60
f(y)=750+60(y-2000) or neatened up a bit...
f(y)=60y-119250 (note: y is the actual year, ie 2005, not year like 2 years from start)
Answer:
x = 308 feet
Step-by-step explanation:
tan = opp/adj
tan72 = x/100
multiply both sides by 100
100 * tan72 = x
Use calculator
x = 307.76835371752534
Rounded
x = 308 feet
Answer:
Step-by-step explanation:
2/5x + 6=3/4x-8
First you would have to multiply $18 (The cost for each month) and 12 (the number of months in a year) and the answer would be 216
So she deducts 216 a year, so the answer would have to be negative
The final answer is -216
The shapes are similar and not congruent because one is 5 units wide while one is less than 5 units. They are the same exact shape but different size making them similar.
