7. Write the explicit formula for the geometric sequence 32, 16, 8, 4,...

Mathematics
1 answer:
ivann1987 [24]3 years ago
4 0

Answer:

The sequence is the ratio of 4:8, or 16:32. This is because the sequence needs to be divided into 2 different factors in order for it to match. The sequence is...

add 4, add 8, add 16, continue on.

The formula is...

4 * x = sequence

In this case, <em>x</em> is the increasing factor. I substituted it due to the fact that it's a constantly increasing number, not just a straight-up number we can declare.

What is the equation in point-slope form of the line passing through (1, 9) and (−1, 11)?
ololo11 [35]
Point slope form: 
y-y_1=m(x-x_1)

m=slope 
(x1,y1) 

First we need to find the slope using the slope formula:
\frac{y_2-y_1}{x_2-x_1} =slope

Given the two coordinates: 
<span>(1, 9) and (−1, 11)

Plug them into the slope formula: 
</span>\frac{11-9=2}{-1-1=-2} =slope
Simplify: 
\frac{2}{-2} =-1
<span>
Now we know that: 
m=-1  and the (x1,y1) would be </span><span>(1, 9)
</span>
Now we simply plug in the info: 
y-9=-(x-1)

Final answer: y − 9 = −(x − 1)

Answer:

The slope intercept form is y=-7x+59

Step-by-step explanation:

y-y=m(x-x1)

y-3=-7(x-8)

y-3=-7x+56

+3 +3
