Write down the 3rd term in the sequence given by: T(n) = n2 + n

1 answer:

8 0

The solution for the problem is:
I will first get the first five terms so that I could easily locate the third term of this problem:So, substituting the values:
T(1) = 1^2 = 1T(2) = 2^2 = 4T(3) = 3^2 = 9T(4) = 4^2 = 16T(5) = 5^2 =25
So the third terms is T(3) = 3^2 = 9

Month 1: 93 in

Elodia [21]

Answer:

9.5 inches per month

Step-by-step explanation:

Given the information about the depth of the pond:

Month 1: 93 in

Month 2: 98 in

Month 3: 112 in

From month 1 to month 3, the average rate of change of the depth of the pond, in inches per month can be calculated using formula

$\dfrac{\text{Depth}_3-\text{Depth}_1}{3-1}$

Hence, from month 1 to month 3, what is the average rate of change of the depth of the pond, in inches per month is

$\dfrac{112-93}{3-1}=\dfrac{19}{2}=9.5\ in/month$

Select the representation that does not change the location of the given point. (4, 110°)

miss Akunina [59]

Answer:

(4,470°)

Step-by-step explanation:

The representation that does not change the location of (4, 110°) in polar coordinates are all points that are coterminal with the given point.

The only point among the given options that is coterminal with (4, 110°) is (4, 470)°

The two points have the same magnitude and 470°-360°=110°.

Since 110° is coterminal with 470° and the two points have the same magnitude with the same sign, the two points represent the same location in polar coordinates.

The correct choice is (4,470°)
