1)What are the first five terms of the sequence given by the formula an=4n+1 ?
koban [17]

Answer:1) c. 5,9,13,17,21

2)  a. a1=8, an=an-1 -2

Step-by-step explanation: 1) an=4n+1

    ⇒ a1=4×1+1=5

         a2=4×2+1=9

          a3=4×3+1=13

          a4=4×4+1=17

           a5=4×5+1=21

2) clearly a1=8 and then the terms of series are decreasing by 2

so, an=an-1 -2

HELPPP THIS IS DUE SOON! I WILL MARK BRAINLIEST
expeople1 [14]

Answer:

7.3

Step-by-step explanation:

For this question, you must use the distance formula. The distance formula is based around Pythagorean Theorem, so you will see some similarities.

Distance = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}

X2 is 7 (X coordinate of school)

X1 is 5 (X coordinate of friend's house)

7 - 5 = 2

2^2 = 4

Y2 is 7 (Y coordinate of school)

Y1 is 0 (Y coordinate of friend's house)

7 - 0 = 7

7^2 = 49

4 + 49 = 53

\sqrt{53} = 7.2801...

<em>Round to the nearest tenth...</em>

<em>7.3</em>

Using the following production tally, determine how many total mousetraps were produced during a shift: Quantity per package: 60
timofeeve [1]
The total number of packages completed was 41 and with 60 moustraps per package so 41 x 60 = 2460. Of these, 52 traps were from the previous shift and 34 were rejects so 2460-52-34 = 2374 produced + 24 in the last unsealed package = 2374 +24 = 2398.
