Determine whether the sequence is arithmetic if so what’s the common difference -9 -33-57-81
QveST [7]

Answer:

Arithmetic.

Common Difference: -24

Step-by-step explanation:

An arithmetic sequence is a sequence with the difference between two consecutive terms constant. The difference is called the common difference. A geometric sequence is a sequence with the ratio between two consecutive terms constant.

For arithmetic, to find the common difference we take any pair of successive numbers, and we subtract the first from the second.

For geometric, to find the common ratio can be found by dividing any term in the sequence by the previous term.

Alex is creating an outdoor structure out of two 12 foot boards. The boards must have an angle of elevation
Whitepunk [10]

Answer:

5.0 ft - 5.6 ft

Step-by-step explanation:

Given that the structure is to be made using two 12 foot boards, then we expect the total perimeter to be equal to (2*12)= 24 ft.

Using the angle of elevation, 40° and the width of 8 ft then you can apply the formula for tangent of a triangle where ;

Tan α = opposite side length/adjacent length

Tan 40°= h/8

h= 8 tan 40° = 6.71 ft

Applying the cosine of an angle formula to find the length of the sliding side

Cosine β = adjacent length /hypotenuse

Cosine 40°= 8/ sliding side length

sliding side length = 8/cosine 40° =10.44 ft

Checking  the perimeter = 10.44 +8+6.71= 25.15 ft

This is more than the total lengths of the boards, so you need to adjust the height as;

24 - 18.44 = 5.56 ft ,thus the height should be less or equal to 5.56 ft

h≤ 5.6 ft

PLEASE HELP!! ASAP!!
mr Goodwill [35]

Answer:

D and E

Step-by-step explanation:

A vertical asymptote in this case would mean that the denominator is equal to zero, which is undefined. You can factor the denominator to get you the fraction:

x+2 / (x+6)(x-4) = 0

Then you know that to equal zero, x would have to equal either -6 or 4, which is E and D.

On Tuesday, you sold $2,889.32 in Regular gas; on Wednesday, you sold $2,996.42, and on Thursday, you sold $3,435.53. If the pri
nika2105 [10]
<span>Add the three amounts first.
$2,889.32 + </span>$2,996.42 + <span>$3,435.53 = $9321.27

Now divide the total amount of sales by the cost per gallon to find the number of gallons.

9321.27/1.19 = 7833

Answer: The total amount of regular gas sold on Tuesday, Wednesday, and Thursday was 7833 gallons.
