Answer:
a) domain: (0, ∞)
b) range: (-∞, ∞)
c) increasing everywhere
d) concave downward
Step-by-step explanation:
a) Your knowledge of the log function tells you it is defined for positive arguments. 9x > 0 means x > 0. The domain is all positive real numbers.
__
b) Your knowledge of the log function tells you it has output values ranging from -∞ to +∞. The range is all real numbers.
__
c) The function is monotonically increasing.
__
d) Since the output does not increase as fast as the input (the first derivative is decreasing), the function is concave downward.
Answer:
1lb. = $1.60
7lb. = $11.20
Step-by-step explanation:
$<u>1</u><u>2</u><u>.</u><u>8</u><u>0</u> = <u>x</u>
8 1
cross multiply
8x= $12.80
divide $12.80÷8x
x= $1.60
Answer:
The Y intercept would be 1. The slope would be 2.
Step-by-step explanation:
The Y intercept is where a line intercepts, or crosses the Y axis. As you can see in the graph, the line crosses the Y axis at point 1.
To find slope here, you can do the rise divided by the run.
To find this, choose two points. We can use point (0, 1) and point (1, 3)
Next, find the rise, or the vertical distance between the two points. In this case, it would be 2.
Then, find the run, or the horizontal distance between the two points. In this case, it would be 1.
Finally, divide the rise by the run, and create the fraction rise over run, or in this case 2/1.
Answer:
3/4 gallons of blueberries
Step-by-step explanation:
we know that
1/2 gallon of blueberries filled the container 2/3 full
so
using proportion
Find out how many gallons of blueberries does it take to fill Sam’s container completely full
Remember that
completely full (100% filled) is the same that the fraction 3/3 or 1
so
