Write the first five terms of the sequence defined by the explicit formula.

AlexFokin [52]

Answer:

(a) 112, 28, 7, (7/4), (7/16)

Step-by-step explanation:

The sequence is given by the explicit formula

$a_{n} = 112 (\frac{1}{4} )^{n-1}$

The terms of the sequence are :

$a_{1} = 112 (\frac{1}{4} )^{1-1} = 112 (\frac{1}{4} )^{0} =112$

$a_{2} = 112 (\frac{1}{4} )^{2-1} = 112(\frac{1}{4} ) =28$

$a_{3} = 112 (\frac{1}{4} )^{3-1} = 112(\frac{1}{4} )^{2} = 7$

$a_{4} = 112 (\frac{1}{4} )^{4-1}=112(\frac{1}{4} )^{3} = \frac{7}{4}$

$a_{5} = 112 (\frac{1}{4} )^{5-1}=112 (\frac{1}{4} )^{4} = \frac{7}{16}$

Find the surface area of a sphere with a diameter 18 cm. Round your answer to the nearest hundredth.

lions [1.4K]

Answer:

1017 sq. cm

Step-by-step explanation:

Surface area:

The surface area of a sphere with radius r is given by:

$S = 4\pi r^2$

In this question:

Diameter of 18, since the radius is half the diameter, $r = \frac{18}{2} = 9$

The surface area is:

$S = 4\pi*9^2 = 1017$

So 1017 square centimeters, and the best option is b.
