Answer:

0.4

Step-by-step explanation:

To get the percentage of a number you must multiply the number by the percentage in float form. Meaning 50% would be 0.5.

Therefore 0.5% would be 0.05.

So multiply 8 by 0.05 and you get the answer 4.

BARSIC [14]

Answer:

x = - 80/17, or x = - 4 $\frac{12}{17}$

Step-by-step explanation:

13x-11 +18×15+ 4x+1=180°

<=> (13x + 4x) + (18×15+ 1 - 11)=180°

<=> 17x + 260 =180

<=> 17x = 180 - 260

<=> 17x = - 80

<=> x = - 80/17

<=> x = - 4 $\frac{12}{17}$

What's an equivalent equation for -5(3-2x)

kobusy [5.1K]

Answer:

-15 + 10x

10x - 15

(either one works)

Step-by-step explanation:

You mean you just want me to expand it?

Ok.

Multiply -5 by 3 and -2x.

(-5)(3) = -15

(-5)(-2x) = +10x

Add those together:

-15 + 10x

10x - 15

The degree of the polynomial function f(x) is 4.

Leto [7]

See the graph below

<h2>Explanation:</h2><h2></h2>

A polynomial function whose degree is 4 is given by the form:

$f(x)=ax^4+bx^3+cx^2+dx+e \\ \\ Or: \\ \\ f(x)=a(x-x_{1})(x-x_{2})(x-x_{3})(x-x_{4}) \\ \\ \\ Where: \\ \\ x_{1},x_{2},x_{3} \ and \ x_{4} \ are \ the \ roots$

Here the roots are:

$x_{1}=-8 \\ \\ x_{2}=-5 \\ \\ x_{3}=1 \\ \\ x_{4}=2$

If we set $a=1$ then:

$f(x)=(x+8)(x+5)(x-1)(x-2)$

Finally, by using graphing tool we get the graph of our polynomial function:
