Answer:
y =
Step-by-step explanation:
x^2 + z^2 = 29^2
x^2 = y^2 + 9^2
y^2 + 20^2 = z^2
29^2 - z^2 = y^2 + 81 (equating for x^2 from eqn 1 and 2)
substitute 3rd eqn in 4th
29^2 - (y^2 + 20^2) = y^2 + 81
841 - y^2 - 400 = y^2 + 81
441 = 2y^2 + 81
360 = 2y^2
y^2 = 180
y =
=
y =
12in/9in = 8in/x in --> 12 * x = 9 * 8 --> 12x = 72 --> 12x/12 = 72/12 --> x = 6
It would be 6 inches wide.
Answer:
- domain: all real numbers
- range: all positive real numbers
Step-by-step explanation:
The function is defined for all values of x, so the domain is all real numbers.
An exponential function has a horizontal asymptote at y=0. Multiplying it by 4 doesn't change that. The value cannot be zero, and it cannot be negative. The range is all positive real numbers.
Yes it is, only that the one on the right is the diminished version of the one on the left. if you look closely you will see that they have divided the measurements by 2 on each side, such as: 10: 2 = 5 6: 2 = 3 and the x is probably 14: 2 which is 7
