Find the distance (7,-8) and (0,2)

Mathematics
1 answer:
Kobotan [32]2 years ago
7 0

Answer:

d = √149 = 12.2

Step-by-step explanation:

Distance between 2 coordinates: d = √[(x2 − x1)^2 + (y2 - y1)^2]

d = √[(0 - 7)^2 + (2 - -8)^2]

d = √[(-7)^2 + (10)^2]

d = √[49 + 100]

d = √149 = 12.2

Isabella drove 600 m and Mia drove 300 more meters than Isabella. If David drove 8.5 km, how much further did David drive in met
Y_Kistochka [10]
Isabella drove 600m.
Mia drove 300 more than Isabella=(600+300)m
=900m.
David drove=8.5km=8500m
Therefore, Distance David drove in meters combined of both distances of Mia and Isabella =[8500-(600+900)]m
=(8500-1500)
=7000 meters or 7 km.

These tables represent an exponential function.Find the average rate of change for the interval from x=8 to x=9
GuDViN [60]

Answer:

Option D. 13122 is the answer.

Step-by-step explanation:

As we can see from the table having interval and average rate of change, figures under average rate of change are forming a geometric sequence.

Sequence is 2, 6, 18 , 54, 162, 486.

and we have to find the average rate of change from x = 8 to x = 9, means we have to find 9th term of the given sequence.

Now we know that explicit formula of the sequence can be written as T_{n}=ar^{n-1}

where Tn is the nth term of the sequence.

a = first term

r = common ratio

n = number of the term

Now from this explicit formula we can find the 9th term of the sequence.

From the given table

a = 2, r = 3, n = 9

T_{9}=2.3^{9-1}=2.3^{8}

T9 = 13122

Therefore Option D. 13122 will be the answer.
