The geometric rule for the nth term of the geometric sequence for which a1 =−6 and a5=−486 is -6 × 3^(n - 1)

<h3>The nth term of a geometric sequence</h3>

First term, a1 = -6

Fifth term, a5 = -486

a5 = ar^(n - 1)

-486 = -6 × r^(5-1)

-486 = -6r⁴

r⁴ = -486 / 6

r⁴ = 81

r = 4√81

r = 3

Geometric rule:

nth term = ar^(n-1)

nth term = -6 × 3^(n - 1)

A man bought a car for 8500 GH cedis and he later sold it at for 9500. find his percentage gain
abruzzese [7]

Answer:

11.7647059 % gain

Step-by-step explanation:

To find the gain, take the new amount and subtract the original amount

9500-8500 = 1000

Divide by the original amount

1000/8500=.117647059

Multiply by 100% to get in percent form

11.7647059 % gain

Describe how to draw a line that passes through the origin and has a slope of -2/3
Bas_tet [7]
Place a dot on the origin.
A line that has a slope of \frac{-2}{3} goes by this formula:
\frac{rise}{run}
So "rise -2" and "run 3."
Rise -2 is basically go down 2, so go down 2 units from the origin. Run 3 means go right 3 units from (0, -2).
Draw a line through (3, -2) and (0, 0).

Write the standard form of the equation of the line through the given point with the given slope. point (-1.0); slope -2/3​
VMariaS [17]

Answer:

Step-by-step explanation:

When given a point and a slope, the best equation to use is the point-slope formula, y - k = m(x - h)

which here becomes:

y - 0 = m(x + 1), or y = (-2/3)(x + 1), or  y = (-2/3)x - 2/3

If you want this in standard form, first clear the fractions by multiplying all terms by 3:  3y = -2x - 2

Now add 2x to both sides, obtaining:  2x + 3y = -2 (in "standard form."

In the figure, RQS QLK.<br><br><br> What is the value of x?<br><br> 36<br> 72<br> 108<br> 144
Lena [83]
The value of x = 108, since the two angles are corresponding, which means they have the same angle, making the angle underneath 108 - 36, which =equals 72, and 72 + 108 = 180
