The triangle is not a right angle

AC = 22 - 8 - 5 = 9
AC² = AB² + BC²
81 = 64 + 25
81 isn't equal to 89, the triangle is not a right angle

The remainder after diving x^4+3x^3-8x^2+5x-9 by x+5 is ____.

raketka [301]

Use the polynomial remainder theorem. It says that a polynomial $f(x)$ has remainder $f(c)$ upon division by $x-c$ .

Here we have

$f(x)=x^4+3x^3-8x^2+5x-9$

and $c=-5$ , so the remainder is

$f(-5)=(-5)^4+3(-5)^3-8(-5)^2+5(-5)-9=\boxed{16}$

(time limit!) what is the volume below? A) 112 B) 224 C) 784 D) 896

Radda [10]

To find a volume of a cylinder we use the following formula:
$v = \pi {r}^{2} h$
Plug in the values:

$v = \pi \times {8}^{2} \times 14$
Take the square:
$v = \pi \times 64 \times 14$
Multiply the numbers:
$v =896 \pi {m}^{2}$

Rudik [331]

Answer:

24hours

Step-by-step explanation:

let Evan be x, Tyler=x-12,equate;1/x+1/(x-12)=1/8,to get x=24 or 4.The correct value of x=24 because if you take x=4 means that Tyler=-8hours which is impossible
