Answer:

a_n= 8-3n is the explicit equation, integers n>0

Step-by-step explanation:

an arithmetic sequence with a first term of 5 and a second term of 2

General formula for arithmetic sequence is a_n= a_1+(n-1)d

where a1 is the first term and d is the common difference

a_1=5

a_2=2

Difference between the terms = 2-5=-3

Difference d=-3

a1=5, d=-3, plug in all the values

a_n= 5+(n-1)(-3)

multiply -3 inside the parenthesis

a_n= 5-3n+3, combine like terms

a_n= 8-3n is the explicit equation, n>0

For the answer to the question above asking the explicit equation and domain for an arithmetic sequence with the first term of 5 and the second term of 2? I think the answer for this is <span>5-2(n-1); all integers where n≥0. I hope this helps.</span>

Answer:

C) The cost increases $2.50 for every additional pair of shoes rented.

Step-by-step explanation:

Notice a pattern. When you buy a new pair of shoes, the total gets increased by $2.50 depending on how many pairs of shoes you buy. For example, starting with 1 pair of shoes, it costs $2.50, but when you buy another pair, the cost is $2.50+$2.50=2*$2.50=$5.00, and so on...

Therefore, the correct choice is C

The measure of angle A to the nearest tenth of a degree is: A 18.5 B 19.5 C 20.5
Andrew [12]

Answer:

B


Step-by-step explanation:

<u>This is a right triangle as shown by the right angle.</u>

  • The side opposite the right angle is the hypotenuse, which is 9.
  • The side opposite angle A is 3.

So we have the opposite of A and the hypotenuse.

The trigonometric ratio that relates opposite side to hypotenuse is SINE.

sin\theta=\frac{opposite}{hypotenuse}

Since, we need angle A, \theta is A, opposite side is 3, and hypotenuse is 9, we substitute:

sinA=\frac{3}{9}\\sinA=\frac{1}{3}

<em>To solve for the angle, we use our calculator and find the inverse sin of \frac{1}{3} :</em>

A=sin^{-1}(\frac{1}{3})\\A=19.47

<em>Rounding to nearest tenth of a degree:</em>

A=19.5

B is the right choice.
