What is the slope of the straight line through points (-2,4) and (5,-1) ?

1 answer:

3 0

The slope can be calculated by subtracting the y values (the rises) and dividing the difference by the difference between the x values (the runs) to get rise over run. -1-4= -5 (differences in y's) & 5-(-2)= 7 (the differences in the x's). now divide the difference in the y' by the difference in the x's to get m= -5/7.

Step-by-step explanation:

<u>Formula:</u> $a^{2}+b^{2}=c^{2}$

$15^{2}+10^{2}=x^{2}$

$225+100=x^{2}$

$x^{2}=325$

$x = 5\sqrt{13}=18.03$

Use 4's and any of the operations: +, -, × and ÷ to write number sentences.

Furkat [3]

Answer:

Step-by-step explanation:

(4x4)÷(4+4) = 2

(4x4)÷ (4 +4) - 4= 4

(4+4)+(4÷ 4)- 4= 5

(4+4)- (4÷4) - 4= 3

Which polynomial function has a leading coefficient of 1 and roots (7 i) and (5 – i) with multiplicity 1? f(x) = (x 7)(x – i)(x

Nuetrik [128]

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

$f(x) = (x - (7 + i)) (x - (5 - i))$

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

$f(x) = (x - (7 + i)) (x - (7 - i)) (x - (5 - i)) (x - (5 + i))$

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

$f(x) = (x^2 - (7^2 - i^2)) (x^2 - (5^2 - i^2)) = (x^2 - 8) (x^2 - 6) = x^4 - 14x^2 + 48$
