4x37
Step-by-step explanation:
only a few ways to get to 148
Answer:
B
Step-by-step explanation:
16,x+4
by completing square formula
All you have to do is plug in the given x values. your first equations would read:
f(-3) = 2^(-3)
f(-2) = 2^(-2)
f(-1) = 2^(-1)
these can be solved by moving decimal points or entering them into a calculator. regardless of the method, your answers are:
f(-3) = 0.002
f(-2) = 0.02
f(-1) = 0.2
so just repeat that process to fill in the rest of your table. to graph it, you'll use them as normal (x, y) points:
(-3, 0.002)
(-2, 0.02)
(-1, 0.2)
the graph might be a little difficult, working with such small values, but precision isn't totally important--0.002 will be super close to 0, 0.02 will be slightly further, 0.2 will be slightly further. the smaller values don't matter as much graphically and you'll recognize the graph of a growing exponential as you graph more of the table.
We take as the 100% the 194070 miles from last year. Then, we apply a rule of three:
Since 329,919 is the 170% of last year's miles, then the increase was of 70%
Answer:
23 buses
Step-by-step explanation:
It comes to 22.3636364 so you need to round up.
