The answer is choice D
-----------------------------------------
Explanation:
We can rule out choice B and choice C which are y = 2.4^x and y = 3.5^x respectively. Why can we eliminate these? Because they are growth functions (the bases are larger than 1). The graph shown is a decay function. It goes downhill as you read it from left to right.
The answer is either choice A or choice D
If we plug in x = -2 into the equations for A and D, we get
y = 0.65^x = 0.65^(-2) = 2.36686
y = 0.32^x = 0.32^(-2) = 9.765625
The result for choice D is much closer to what the graph is showing. The graph appears to have the point (-2,11) on the curve. So that's why choice D is the best answer.
Note: the graph is a bit small and its not entirely clear which points are on this graph other than (0,1). So this is a bit of educated guesswork.
1). The inequality says "height is 54 or more".
Any height that is less than 54 does NOT qualify.
2). The sign says "Maximum total weight 800 pounds".
Any weight that's 800 pounds or less is OK.
3). Paula has scored 21, 25, and 15 points.
. . . . . they're NOT all greater than 21
. . . . . they ARE all 25 or less
. . . . . they ARE all less than 30
. . . . . they ARE all 10 or more .
4). First, write down the number of cans that
each student collected, but arrange them in order.
Then check each choice.
A). misses the highest 3 students completely
B). includes everybody
C). misses the lowest 3 students completely
D). OK, but the first and last intervals aren't needed,
because nobody's cans are in those intervals
Answer: -15 meters
Step-by-step explanation:
Given: The Tunnel of Fear ride climbs straight up to its peak above the ground = 50 meters or +50 meters
Then, it drops into an underground tunnel = 65 meters or -65 meters
Thus, the elevation of the tunnel relative to the ground= +50-65=-15 meters
Hence, the elevation of the tunnel relative to the ground= -15 meters.
I think the answer is B. Or A.
Answer:
When it's negative when it goes to the other side it becomes a positive.....
Y=(x-4)(x-1)
Make y 0 when your calculating for x
Make x 0 when your calculating for y
0=(x-4)(x-1)
Therefore x=4 or x=1
