Find the common difference of the arithmetic sequence -7,-4,-1,...

Answers

Answer: 3

Step-by-step explanation: The common difference of an arithmetic sequence is the constant difference between consecutive terms. To find the common difference, we can subtract any term from its previous term. In this case, we can subtract -4 from -7 or -1 from -4. Both subtractions yield a result of 3. Therefore, the common difference of the arithmetic sequence -7, -4, -1, … is 3

Each of the letters in the word APPLE is on separate cards, face down on the table. If you pick a card at random, what is the probability that its letter will be A or L?

Answers

Probability =

(number of possible ways to succeed)
divided by
(total number of possible outcomes) .

Number of ways to succeed = 2 (pick the 'A' or the 'L')

Total number of possible outcomes = 5 (the cards on the table) .

Probability of success = 2/5 = 40% .

A 50 ft tall tree is casting a shadow while the sun is at an angle of elevation of 63  . to the nearest foot, how long is the tree's shadow?

Answers

Remark

The question is an application of the Tangent Function.

Tan(63) = Opposite / Adjacent

Givens

Opposite side = height of the tree = 50 feet.

Adjacent side = shadow length which we have to solve for.

Solution

Tan(63) = opposite/ Adjacent Add a 1 on the left so you have a proportion.

Tan(63)/ 1 = 60 / adjacent Cross multiply

Adjacent * Tan(63) = 1 * 60

Adjacent = 60 / tan(63)

Adjacent = 60 / 1.963

Adjacent = 30.57 feet.

Alberto wants to keep their favorite tree from being uprooted by heavy winds. They plan to tie 3 sections of rope to a band on the trunk of the tree, 5 feet above the ground. They will tie each section of the rope to a stake in the ground 12 feet out from the base of the tree. How much rope will he need altogether?

Answers

Answer:

39 ft

Step-by-step explanation:

Using the description as a guideline I have drawn out the situation (badly drawn) as seen in the picture below. From the picture, we see that we need to find x which is the length of one of the ropes. Once we have this length we simply multiply it by 3 to find out how much rope we need altogether. Since this is the diagonal of a triangle we can use the Pythagorean theorem to solve for x.

Pythagorean theorem: $a^(2) +b^(2) = c^(2)$ .... which a and b are the two sides while x is the diagonal.

$5^(2) +12^(2) = x^(2)$

$25 + 144 = x^(2)$

$169 = x^(2)$ ... now we square root both sides

$13 = x$

Now that we have the length of one of the ropes we simply multiply this by 3 to find the total amount of rope needed.

13 * 3 = 39 ft
