Well first of all if I had a multiplication question such as 12,000×1000 of course you would know it would be 12,000 well you would always use your place value chart saying ones tens hundreds thousands and thousands and hundreds

If you had a problem like 80x20 you wouldn't know what that was but you can take out the 0's and do 8x2 which is 16 then add back both 0's to make 1,600

Answer:

  36, 32, 28, 24

Step-by-step explanation:

Fill in the values of n and do the arithmetic.

  a1 = 36 -4(1 -1) = 36

  a2 = 36 -4(2 -1) = 32

  a3 = 36 -4(3 -1) = 28

  a4 = 36 -4(4 -1) = 24

_____

You could recognize the formula as the specific case of the explicit formula for an arithmetic sequence with first term 36 and common difference -4. That tells you the second term is 36 -4 = 32, and each successive term is 4 less than the one before.

Find the exact values of the remaining five trigonometric functions of o satisfying the given conditions.
Lyrx [107]

First, tan(<em>θ</em>) = sin(<em>θ</em>) / cos(<em>θ</em>), so if cos(<em>θ</em>) = 3/5 > 0 and tan(<em>θ</em>) < 0, then it follows that sin(<em>θ</em>) < 0.

Recall the Pythagorean identity:

sin²(<em>θ</em>) + cos²(<em>θ</em>) = 1

Then

sin(<em>θ</em>) = -√(1 - cos²(<em>θ</em>)) = -4/5

and so

tan(<em>θ</em>) = (-4/5) / (3/5) = -4/3

The remaining trig ratios are just reciprocals of the ones found already:

sec(<em>θ</em>) = 1/cos(<em>θ</em>) = 5/3

csc(<em>θ</em>) = 1/sin(<em>θ</em>) = -5/4

cot(<em>θ</em>) = 1/tan(<em>θ</em>) = -3/4

Jennifer spent $42 on a magazine and 7 candy bars. The magazine cost $7, then how much was each candy bar​
Genrish500 [490]
$5. You subtract the $7 from the $42 since that was the magazine then you divide that(35) by 7 since that is the amount of candy bars that were bought. That’ll give you the answer of $5 for each candy bar.
