Does the following infinite series converge or diverge?

Mathematics
1 answer:
IRISSAK [1]3 years ago
3 0

Look like that first one is supposed to have a denominator of 2.

This is a geometric series with a common ratio 4, so it diverges (absolute value 1 or more), meaning it has no sum.  Choice C.

A walking path across a park is represented by the equation Y equals negative 2X -7. A new path will be built perpendicular to t
Ulleksa [173]

So we are given an initial equation of: y=2x-7.

We are told that a new path is going to be perpendicular to this line. So to find a slope that is perpendicular to a line, we take the slope of the known line (in this case 2) and we flip it and change the sign. So since this slope is essentially \frac{2}{1}, we are going to flip it to make it \frac{1}{2} and change the sign to make it -\frac{1}{2}.

So now we know that the slope of the perpendicular line is -\frac{1}{2}, we can start a new equation for this line:

y=-\frac{1}{2}x+b

We are also told that the path will intersect at (-2,-3) - this is a solution to the two lines. So to find b in this new equation, let's plug in the x and y values found in the point:

-3=-\frac{1}{2}(-2)+b

Then solve for b:

-3=1+b

b=-4

So then we plug in our value for b and leave x and y:

y=-\frac{1}{2}x-4

So this equation now represents the new path.

What is the simplified expression for 3a²+9ab+5-4a²-4ab+3 ​
zheka24 [161]

Answer:

5ab + 8 - 1a^2.

Step-by-step explanation:

Combining like terms, we get 3a^2 - 4a^2 = -1a^2. We get 9ab - 4ab = 5ab. Then we get, 5 + 3 = 8. Together this is 5ab + 8 - 1a^2
