What the length of the hypotenuse of an isosceles right triangle whose legs are 1 unit in length.

≈ 1.414

Step-by-step explanation:

You can use the pythagorean theorem, a^2 + b^2 = c^2

a^2 and b^2 are the legs and c^2 is the hypotenuse.

1^2 + 1^2 = c^2

1 + 1 = c^2

2 = c^2

√ 2 = √ c^2

c = ≈ 1.414

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

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
