41.6 I believe. If my calculations are correct that should be the answer.

To figure this out you divide 80 by 48 and then multiply by 100%.
48/80=0.6
0.6x100%=60%
48 is 60% of 80

one factor of f(c) = 5x3 + 5x2 - 170x + 280 is (x + 7). What are all the roots of the function? Use the remainder theorem

elena55 [62]

Answer:

So the roots of the polynomial are -7 , 4 , 2

Step-by-step explanation:

Given the polynomial in the question

5x³ + 5x² - 170x + 280

One of the factor of this polynomial is (x + 7)

By using remainder theorem

5x²-30x+40

-----------------------------------

x+7 | 5x³ + 5x² - 170x + 280

5x³ + 35x²

----------------------------

-30x² -170x + 280

-30x² -210x

------------------

40x + 280

----------------

So the polynomial we have is

5x²- 30x + 40

divide by 5

x² - 6x + 8

(x-4)(x-2)

So the roots of the polynomial are -7 , 4 , 2

5x+6y=18and 18x-15y=36 parallel or perpendicular

Katen [24]

Answer:

They are neither parallel nor perpendicular, since slope are different and not related by any equation

Step-by-step explanation:

First arrange them according to general equation:

$y = mx + c$

for the first equation :

$5x + 6y = 18 \\ 6y = - 5x + 18 \\ { \boxed{y = - \frac{5}{6} x + 3}}$

for the second equation :

$18x - 15y = 36 \\ 15y = 18x - 36 \\ y = \frac{18}{15} x - \frac{12}{5}$
