Answer:

The answer is " $\bold{\frac{1}{4}$ "

Step-by-step explanation:

Given:

$\ S_1 = k \\\\ S_{n+1} = \sqrt{4S_n -1}$ $_{where} \ \ n \geq 1$

In the above-given value, $S_n$ is required for the monotone decreasing so, $S_2 :$

$\to \sqrt{4k-1} \leq \ k=S_1\\\\$

square the above value:

$\to k^2-4k+1 \leq 0\\\\\to k \leq 2+\sqrt{3} \ \ \ \ \ and \ \ 4k+1 >0\\\\$

$\bold{\boxed{\frac{1}{4}$

Answer:

$-4$

Step-by-step explanation:

Step 1: Apply the rule

$\left(-64\right)=-64\\\\=\sqrt[3]{-64}$

Step 2: Apply the radical rule

$\sqrt[3]{-64}=-\sqrt[3]{64}\\\\=-\sqrt[3]{64}$

Step 3: Factor the number

$\:64=4^3\\\\=-\sqrt[3]{4^3}$

Step 4: Apply the radical rule

$\sqrt[3]{4^3}=4\\\\=-4$

Therefore, $\:\sqrt[3]{\left(\:-\:64\right)}\:=\:-4$

On a coordinate plane, a line goes through (negative 3, 2) and (0, 1). A point is at (3, 4). What is the equation of the line th

Novay_Z [31]

Answer:

$y=3x-5$

Step-by-step explanation:

step 1

Find the slope of the given line

we have

(-3,2) and (0,1)

The slope m is

$m=(1-2)/(0+3)=-1/3$

step 2

Find the slope of the line perpendicular to the given line

Remember that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of its slopes is -1)

The slope is

$m=3$

step 3

Find the equation of the line in point slope form

we have

$m=3$

$point(3,4)$

$y-4=3(x-3)$ ----> equation in point slope form

Convert to slope intercept form

$y=3x-9+4$

$y=3x-5$
