ln 5
e = ?
x
Keep in mind that y=e and y = ln x are inverse functions of one another.
ln 5
e , we can drop both the "e" and the "ln 5." We are left with 5 (answer).
ln 5
Alternatively, we could take the ln of both sides of y = e
which will result in ln y = (ln 5) ln e. Note that ln e = 1 (these two functions are inverses of one another).
Then we are left with ln y = ln 5. Dropping the "ln" operator from both sides,
y=5 (same as before).
Answer:
-224
Step-by-step explanation:
xyz^2
(2)(7)(-4)^2
14 x -16
-224
For f(-2), x will equal -2.
Plug the x-value into the equation:

A negative exponent means that the term turns into a fraction, with 1 as the numerator and the positive exponent as the denominator.
Solve 2^(-2):

Solve the problem:

f(-2) will equal
1/2.
Josie's height = 5 ft 6 in. = 5 1/2 ft = 11/2 ft.
Josie's shadow = 6 ft.
Ratio of shadow to height = 6 / 11/2 = 12/11
So, It would be equal to ratio of building's shadow to building's height.
18/x = 12/11
x = 18*11 /12
x = 3*11 / 2
x = 16.5
In short, Your Answer would be 16.5 Feet
Hope this helps!
Answer:
∠A = 32°
Step-by-step explanation:
Using the tangent ratio in the right triangle
tanA =
=
= 0.625, thus
A =
(0.625) = 32°
