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 :

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

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

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

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

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

PLEASE HURRY!!! What is the slope of the line that passes through (4, 5) and (8, -1)

Nitella [24]

Answer:

-1.5

Step-by-step explanation:

The slope of a line is given by the formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

Let's let (4,5) be x₁ and y₁ and let's let (8,-1) be x₂ and y₂. So:

$m=\frac{-1-5}{8-4}$

Subtract:

$m=\frac{-6}{4}$

Reduce:

$m=-\frac{3}{2}=-1.5$

So, our slope is -3/2 or -1.5.

And we're done!
