Answer:
Step-by-step explanation:
Notice that each new term in the arithmetic sequence 1, -1, -3, ... is 2 less than the previous term. Thus, the common difference is -2.
The formula for this sequence is a(n) = 1 - 2(n - 1), or a(n) = 3 - 2n
Answer:
x = 12.489996 ft
Step-by-step explanation:
In order to solve one side length of a right triangle given two of other side lengths, you can use the pythagorean theory.
The theory states that the sum of the two adjacent side squares equals the square of the hypotenuse.
Basically:
Since the problem gives you the hypotenuse and one adjacent side length you rearrange the formula as so:
Then plug in the values:
I am pretty sure you subtract but in case it would be
(23,43) - (17,14).
(6,19) should be the answer
Answer:

Answer:
Step-by-step explanation:
Solution
This (after combining the top 2 fractions, is a 4 tier fraction.
1/4*3/4 = 3/16
So the question now becomes 3/16 ÷ 10/3
The rule for such a question is invert (turn up side down) the second fraction and multiply.
3/16 * 3/10 Combine
(3*3)/(16* 10)
9 / 160
0.05625
