Answer:
Step-by-step explanation:
4a: x=729
4b: x=9/25
5a ln (2)
5b log2(24
Answer: Choice A
The axis of symmetry for the function is x = 0.
===========================================================
Explanation:
The vertex is on the axis of symmetry. Since the vertex is on the y axis, this means the y axis itself is the axis of symmetry. The y axis is represented by the equation x = 0. Every point on the y axis has an x coordinate of 0. Example points are (0,2) and (0,5).
This parabola may have 0 roots, 1 root, or 2 roots.
If the line has a slope of -9, the slope of any parallel line will also be -9.
Parallel lines always have the same slope.
Answer: D is correct, 52.9%
Step-by-step explanation:
% decrease from 340 to 160, Where 340 is the old number and 160 is the new number
Percent change = (New number - Old number) / Old number x 100%
Percent change
= (160 - 340) / 340 x 100
= (-180) / 340x 100 = -52.94%
I hope this is clear, please mark as brainliest answer.
Answer:
20 blocks per pound.
Step-by-step explanation:
In this question we have to determine the approximate number of blocks per pound, means we have to determine the slope of the given line in the graph.
Here end points of the line are origin (0,0) and (5,100).
Now the slope will be m = (y - y')/(x - x') = (100-0)/(5-0) = 100/5 = 20
Therefore the answer will be 20 blocks per pound.
