A robot can complete 5 tasks in 2/3 hour. Each task takes the same amount of time.

Natasha2012 [34]

Answer:

5 tasks = 2/3 hour.

1 task = 2/3 hour /5 = 2/15 hour.

How many tasks can the robot complete in one hour?

1 hour / (2/15 hour/task) = 15/2 tasks = 7.5 tasks.

Write an explicit formula for the An, and the n^th term of the sequence 24,-12,6,....

Annette [7]

Answer:

$T_n = -48* (-\frac{1}{2})^{n}$

Step-by-step explanation:

Given

$24, -12, 6,...$

Required

Write a formula

The above sequence shows a geometric sequence because:

$r = \frac{-12}{24} = \frac{6}{-12} = -\frac{1}{2}$ -- common ratio

The equation is determined using:

$T_n = ar^{n-1}$

Where

$a = 24$

Substitute values for a and r

$T_n = 24* (-\frac{1}{2})^{n-1}$

Apply law of indices:

$T_n = 24* (-\frac{1}{2})^{n} * (-\frac{1}{2})^{-1}$

$T_n = 24* (-\frac{1}{2})^{n} * 1/(-\frac{1}{2})$

$T_n = 24* (-\frac{1}{2})^{n} * 1*-2$

$T_n = 1*-2*24* (-\frac{1}{2})^{n}$

$T_n = -48* (-\frac{1}{2})^{n}$

<em>The above represents the explicit formula</em>

Find the volume of a right circular cone that has a height of 11.9 ft and a base with a radius of 16.3 ft. Round your answer to

vivado [14]

Answer:

3311.36ft^3

Step-by-step explanation:

Given data

Height h= 11.9ft

Radius=16.3ft

The expression for the volume of a cone is given as

Volume= 1/3πr^2h

substitute

Volume=1/3*3.142*16.3^2*11.9

Volume= 1/3*3.142*265.69*11.9

Volume= 1/3*9934.095962

Volume=3311.36ft^3

Hence the volume is 3311.36ft^3
