Answer:
29.05 ft
Step-by-step explanation:
Using the concept of pythagoras theorem, here we have the base and hypotenuse given hence we need to find the third dimension, assuming the wall is perfectly straight and forms a right angle with the bsse of the ladder. Here,
and making a the subject of the formula then
and substituting 30 ft for c and 0.25*30=7.5 ft for b then
Answer:
x-intercept = -6 y-intercept = 9
Step-by-step explanation:
For this case we must find an expression equivalent to:

To express in scientific notation we must take into account that the power will be positive, that is, the decimal is run to the right.
We test each option.
Option A:

If we run the decimal 9 spaces to the left we have:

Option B:
We discard it because the exponent is negative.
Option C:

We run the decimal 6 spaces to the right

Option D:

We run the decimal 9 spaces to the right

Answer:
Option D
