Answer: 11.4 m

Step-by-step explanation:

The scenario depicted is that of a right angled triangle with the 7 meters being the base and the 9 meters being the height.

The length of the ladder will therefore be the Hypothenuse.

Using the Pythagorean Rule:

a² + b² = c²

with c being the hypothenuse

7² + 9² = c²

49 + 81 = c²

c²= 130

c = √130

c = 11.4 m

What is the end behavior of the function f(x)= -3x^7+4x^5-14?
adoni [48]

Answer:

  • f(-∞) → ∞
  • f(∞) → -∞

Step-by-step explanation:

The degree of the function is odd, so the ends tend in opposite directions. The leading coefficient is negative, so the right end (as x gets large) will tend toward -∞. Then the left end tends toward +∞.

_____

If the degree is even, both ends tend in the same direction. That direction matches the sign of the leading coefficient.
