Answer:

-1/5

Step-by-step explanation:

When a line is perpendicular to another line, it's gradient will be a reciprocal.

To calculate the reciprocal of a number you have to flip the fraction the other way around.

So, in the case our current gradient is 5/1 (5/1 is the same as just 5) and we need to flip in over to get 1/5, which is our new gradient.

The final step is to make the number negative because the line is going down. This gives us the final answer of -1/5.

Find the slope of the line passing through the points (0,12) and (4,3)

anzhelika [568]

The slope is the change in Y over the change in X:

Slope = (3 -12) / (4-0)

Slope = -9/4

The answer is the 3rd choice.

Jamie is training for a race and is running laps around a field. If the distance around the field is 350 yards, how many complet

Feliz [49]

First convert 6 miles to yards. That would be 10,560 next divde it by 350 to get 30.1786 but you have to round it to the next lap. Therfore, youll have to run a total of 31 laps around the field.

But, the expanded form of this is

1,000,000 - Millions Place

200,000 - Hundred Thousands

50,000 -Ten Thousands

4,000 -Thousands

300 - Hundreds

The sum of the first 100 terms of the arithmetic series is of 58,900.

<h3>What is an arithmetic sequence?</h3>

In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.

The nth term of an arithmetic sequence is given by:

$a_n = a_1 + (n - 1)d$

In which $a_1$ is the first term.

The sum of the first n terms is given by:

$S_n = \frac{n(a_1 + a_n)}{2}$

For this problem, the parameters are:

$a_1 = -5, d = 12, n = 100$

Then:

$a_{100} = -5 + 99(12) = 1183$

Hence the sum is given by:

$S_{100} = 50(-5 + 1183) = 58,900$
