Answer:

The final angle is 50

Step-by-step explanation:

All quadrilaterals have interior angles that add up to 360. So we can subtract these numbers from 360 to get the final angle.

360 - 90 - 100 - 120 = 50

given a polynomial with factor (x - a)

Then x = a is a root of the polynomial and f(a) = 0

(1)

(x+ 2) is a factor , hence x = - 2 is a root

Evaluate the polynomial for x = - 2

f(- 2) = 5(- 2)³ + 8(- 2)² - 7(- 2) - 6 = - 40 + 32 + 14 - 6 = 0

Hence (x + 2 ) is a factor

(2)

If (x + 1) is a factor then x = - 1 is a root

5(- 1)³ + 8(-1)² - 7(- 1) - 6 = -5 + 8 + 7 - 6 = 4

Since f( - 1) ≠ 0

Then (x + 1) is not a factor

You practice your basketball shots every day. On Friday you made 20 shots. On Saturday you made 16 shots. What is the percent de

STatiana [176]

So,

All you have to do to find the percent decrease is to subtract your score on Saturday from your score on Friday and divide the result by your score on Friday. If you let "f" represent your score on Friday and let "s" represent your score on Saturday, you can re-write this mathematically:

$\frac{f - s}{f} = percent\ decrease$

Substitute.
$\frac{20 - 16}{20} = percent\ decrease$
$\frac{4}{20} \ or\ \frac{1}{5}\ or\ twenty\ percent = percent\ decrease$

The percent decrease in shots you made was 20%. That would be option C.
