Answer:

Step-by-step explanation:
The formula of a slope:

If
m > 0, then a line is rising
m < 0, then a line is falling
m = 0, then a line is horizontal
m is undefined, then a line is vertical
<h2>a.</h2>
(2, 1) and (4, 5)

<h2>b.</h2>
(-1, 0) and (3, -5)

<h2>c.</h2>
(2, 1) and (-3, 1)

<h2>d.</h2>
(-1, 2) and (-1, -5)

It looks like you might have intended to say the roots are 7 + i and 5 - i, judging by the extra space between 7 and i.
The simplest polynomial with these characteristics would be

but seeing as each of the options appears to be a quartic polynomial, I suspect f(x) is also supposed to have only real coefficients. In that case, we need to pair up any complex root with its conjugate to "complete" f(x). We end up with

which appears to most closely resemble the third option. Upon expanding, we see f(x) does indeed have real coefficients:

Answer:
Step-by-step explanation:
4 hours × (¼ in)/hour = 1 in
6 hours × (½ in)/hour = 3 in
Total snowfall over ten hours = 1 + 3 = 4 in
Answer:
x = 20 * s / 300
Step-by-step explanation:
In this case, it is solved by means of a rule of three, that is, we know that 20 of 300 answered yes, but in the case of the strata sample, since it is a value that is not mentioned in the problem, we will assume it as " s "and the people who were selected as" x ". would:
20 x
300 s
Therefore, x:
x = 20 * s / 300
and thus they would give us the number of people that would be selected.
For example, if "s" were 240, it would be:
x = 20 * 240/300
x = 16
that is, 16 people would be selected
