You are given = 4
You re also given = -5
To find a, use the exponential form:
Then you can convert into a logarithm.
Answer:
32 oz
Step-by-step explanation:
Assuming the hole in the bottle is not made any bigger as it loses water, it will lose it at a constant rate. This makes it a linear function. We can use the 2 points given to find the slope of the line, then use one of the 2 points to write an equation for the line in point-slope form, change it into slope-intercept form, and the amount of water in the bottle originally will be apparent. Plugging in to the slope formula:
Now we will choose one point for the x and y values and plug in to the point-slope form of a line:
y - 28 = -2(x - 2) and
y - 28 = -2x + 4 so
y = -2x + 32
That is in y = mx + b form where m is the slope and b is the y-intercept, the initial value of y when x = 0. x being the time gone by, when x = 0, that means that no time has gone by, and that means that no water has yet to leak out of your bottle.
0.3
0.1 is one tenth. Three tenths of the animals are horses. So, you just take 0.1*3 and get 0.3, or three tenths.
