artcher [175]

Answer:

It is given that the North Pole is at a distance of 3,949 miles from the center of the earth. We also know that the sea floor is below 2.4 miles from the sea level. 3949 - 2.4 = 3946.6 miles

When solving the system of equations 3x−3y=1 and −2x+4y=2 algebraically, a good first step is to:

bearhunter [10]

Answer:

A. Multiply 3x−3y=1 by 2, and multiply −2x+4y=2 by 3.

Step-by-step explanation:

Given

$3x - 3y = 1$

$-2x+ 4y = 2$

Required

A good first step

A good first step is to eliminate x and this is done as follows:

Multiply $3x - 3y = 1$ by 2 (gotten from coefficient of x in the second equation)

Multiply $-2x+ 4y = 2$ by 3 (gotten from coefficient of x in the first equation)

This gives:

$6x - 6y = 2$

$-6x + 12y = 6$

Add both equations

$6x - 6x - 6y + 12y = 2 + 6$

$6y = 8$

$y = \frac{4}{3}$

<em>Hence (a), is true</em>

You drop a ball from a height of 0.5 meters. Each curved path has 52% of the height of the previous path. a. Write a rule for th

Verizon [17]

Answer:

a) $a_n = 50 (0.52) ^ {n-1}$

b) $a_6 = 50 (0.52) ^ 5 = 1.90\ cm$

Step-by-step explanation:

If each curved path has 52% of the previous height this means that $\frac{a_{n+1}}{a_n} = 0.52$

Then the radius of convergence is 0.52 and this is a geometric series.

The geometric series have the form:

$a_n = a_1 (r) ^ {n-1}$

Where

$a_1$ is the first term of the series and r is the radius of convergence.

In this problem

$a_1 = 0.5$ meters = 50 cm

$r = 0.52$

a) Then the rule for the sequence is:

$a_n = 50 (0.52) ^ {n-1}$

b) we must calculate $a_6$

$a_6 = 50 (0.52) ^ 6-1\\\\a_6 = 50 (0.52) ^ 5 = 1.90\ cm$
