Indicate the general rule for the arithmetic sequence with a3 = -4 and a8 = -29.

1 answer:

7 0

Calculate first the common difference of the arithmetic sequence,
d = (-29 - -4)/(8 - 3) = -5
The first term is calculated through the way below,
a1 = -4 + 5 + 5 = 6
Thus, the first term of the arithmetic sequence is 6 and the common difference is -5.

What if the perimeter and area for the following figure?

babymother [125]

Answer:

Perimeter of the circle = 31.42 in(exact value) ≈ 31.40 in (approximate value)

Area of the circle = 78.55 in²

Step-by-step explanation:

Given:

Radius = 5 in

To Find:

Area & Perimeter of the circle

Solution:

<h3>Perimeter of the circle:</h3>

We know that,

Perimeter = 2πr

Taking π as 3.142 and substituting values,we obtain

Perimeter = 2*5*π
Perimeter = 10π
Perimeter = 10*3.142
Perimeter = 31.42 ≈ 31.40 in

<h3>Area of the circle:</h3>

We know that,

Area = πr²
Area = π(5²)
Area = 25π
Area =25*3.142
Area = 78.55 in²
