Answer:

<u>The height of the tree is √65 or 8.06 feet</u>

Step-by-step explanation:

Let's use the Pythagorean theorem to find out the height of the tree, this way:

Hypotenuse = length of the ladder = 9 feet

Leg 1 = Distance from the base of the tree to bottom of the ladder = 4 feet

Leg 2 = Height of the tree

Now, replacing with the real values we have:

Leg 2 ² = Hypotenuse² - Leg 1²

Leg 2² = 9² - 4²

Leg 2² = 81 - 16

Leg 2² = 65

√Leg 2² = √65

Leg 2 = √65 or 8.06 feet

<u>The height of the tree is √65 or 8.06 feet</u>

Answer:

Andre.

Step-by-step explanation:

Andre's group was asked to write an expression equivalent to 5p²q + 7pq² - 10.

Andre gives the expression 7p²q + 7pq² - 1 - 2p²q - 9, which gives the expression 5p²q + 7pq² - 10.

Jill gives the expression 5p²q + 2 pq² - 6 + 5pq² - 3, which does not give the expression 5p²q + 7pq² - 10.

Now, Anuj gives the expression 4p²q + 7pq²- 7 + 2p²q - 3, which also does not give the expression 5p²q + 7pq² - 10.

Again, Marsha gives the expression 5p²q + 5 pq²- 10 + 3pq², which also does not gives the expression 5p²q + 7pq² - 10.

Hence, only Andre gives the correct expression. (Answer)

Given f(x)<br> 6x – 5<br> a) Evaluate f(5)<br> f(5)<br> b) Evaluate f( - 3)<br> f(-3) =
prisoha [69]
We have the equation f(x)=6x-5 to start with
Now in order to answer the question we have to know that f(5) is the same thing as setting x=5 and solving for f(5)

(A) f(5) = 6(5) - 5 = 30 - 5 = 25
(B) f(-3) = 6(-3) - 5 = (-18) - 5 = -23

So f(5) = 25 and f(-3) = -23
