Answer:
y = -2·(1/2)^x
Step-by-step explanation:
The general form of the equation can be written as ...
y = a·b^x
where 'a' is the value of the y-intercept, and 'b' is the ratio of y-values for x-values that differ by 1.
From your table and graph, a = -2. From the table, ...
b = -1/-2 = 1/2
Then the exponential equation is ...
y = -2·(1/2)^x
Answer:
a. 7 times
b. 74.7 km
Step-by-step explanation:
a. From Albany to Pittsburgh, there are 739.7 km.
She stopped to rest after every 95 kilometres:
Therefore, let us find how many times she stopped:
739.7 / 95 = 7.79
We only need the quotient, that is, 7
So she stopped 7 times.
b. After her last stop, she had traveled:
7 * 95 = 665 km
Therefore, the distance she has left after her last stop is:
739.7 - 665 = 74.7 km
C. because you would put in the number for an example 4=2(2) and 2+4=6
Answer:
are there options? if so can you add them?
Step-by-step explanation:
In order to decide which option is correct we need to check the relation of meter to centimeter, kilometer and millimeter.
From the given options, we can see that 1 meter is not equal to 103 mm and 0.01 km.
Hence, B and C are correct.
A meter is not equal to 103 mm and 0.01 km.
