A 20-foot ladder is leaning against a tree. The bottom of the ladder is 12 feet away from the bottom of the tree. Approximately
jarptica [38.1K]

Using the Pythagorean Theorem we can solve.


20^2 - 12^2 = X^2

400 - 144 = X^2

256 = X^2

X = √256

X = 16 feet.


The answer is D.

Please answer the following
natulia [17]

Answer:

cot∅ = (-2√30)/7.

Step-by-step explanation:

Given the value of csc∅ = -13/7 and ∅ is in quad III.

We know y = r sin∅ and r > 0. So csc∅ = r/y = -13/7 = 13/(-7).

It means y = -7, r = 13.

We know x² + y² = r².

x² = r² - y²

x² = (13)² - (-7)² = 169 - 49 = 120.

x = √120 = 2√30.

we know cot∅ = x/y = (2√30)/(-7) = (-2√30)/7.

Hence, cot∅ = (-2√30)/7.

Is (x+7) a factor of f(x) x3-3x2+ 2x-8?
Snowcat [4.5K]

Answer:

(x+7) is not a factor

Step-by-step explanation:

we know that

If (x+7) is a factor of f(x)

then

For x=-7, f(-7)=0

Verify

we have

f(x)=x^{3}-3x^{2} +2x-8

Substitute x=-7

f(-7)=(-7)^{3}-3(-7)^{2} +2(-7)-8

f(-7)=-343-147 -14-8

f(-7)=--512

-512\neq 0

therefore

(x+7) is not a factor
