Find BC.
Round to the nearest tenth.

11.4

Step-by-step explanation: We can use the Pythagorean Theorem to find the value of BC, which is a^2 + b^2 = c^2, a being BA and AC being b and BC being c. This being 7^2 + 9^2 = c^2.

This is 49 + 81 = c^2, thus, the square root of 130 is 11.4 rounded.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
