Try looking at the question like this.
You have 0 tenths (00)
You have 0 hundreds (000)
<u>You have 9 thousands (9000)</u>
You have 50 thousands, (50,000)
You have 700 thousands (700,000)
You have 6 millions (6,000,000).
To determine which number it is rounded to, simply look at which has an actual number in it. 9,000ths is the first slot with a number, which means the number is rounded to the nearest thousand. If it was 6,759,800, it would be rounded to the nearest hundredth and so on...
Answer:
Letter A.
Step-by-step explanation:
One way to know that two lines are perpendicular IF their slopes are reciprocals of one another and one slope is negative.
Slope AB is -3/4 and the slope of CD is 4/3.
- 3/4 is the reciprocal of 4/3
- One slope is negative (-3/4)
Answer:
B
Step-by-step explanation:
The exponential function has the form where a is the starting value or y-intercept. B is the rate of change and x is the variable typically time. In this situation, has starting value 4, rate 3 and a -x.
Normally an exponential curve glides left to right growing steeper as it goes. But a -x flips this behavior. The curve starts very steep then gradually slows down. This means only graphs B or D are options. Since only graph B of these two has a y-intercept at 4, graph B is the solution.
