Answer:
In the year 2010, the population of the city was 175,000
Step-by-step explanation:
If we rewrote this as a linear expression in standard form (it is linear, btw), it would look like this:
The rate of change, the slope of this line, is 11/2. If the year 2010 is our time zero (in other words, we start the clock at that year), then 0 time has gone by in the year 2010. In the year 2011, t = 1 (one year goes by from 2010 to 2011); in the year 2012, t = 2 (two years have gone by from 2010 to 2012), etc. If we plug in a 0 for t we get that y = 175,000. That is our y-intercept, which also serves to give us the starting amount of something time-related when NO time has gone by.
Answer:
Step-by-step explanation:
(-12+50)/(-2-3)+72/(4+2)
simplify: 38/67/6
multiply by the reciprocal: 38/67*6/1
you get: 228/67
decimal: 3.402985075
Answer:
The measure of the missing side length = 45
Step-by-step explanation:
Pythagorean Theorem states: A² + B² = C²
28² + B² = 53²
784 + B² = 2809
B² = 2809 - 784
B² = 2025
B = 
B = 45
Therefore the measure of the missing side length = 45
Hope this helps!
The function rule is -1/5
Answer:
-62/23 degrees per hour
Step-by-step explanation:
Do this by dividing the total change in temperature (-15 1/2 degrees) by the total elapsed time (5 3/4 hrs):
-31/2 degrees -62/4 degrees Note: convert 31/2 to 62/4
--------------------- = ------------------------ = -62/23 degrees per hour
23/4 hrs 23/4 hrs
