9.42 Units

Step-by-step explanation:

Since the angle shown is 90 degrees we can deduce that the rest of the arc is 270 degrees therefore we can make the fraction:

270/360; 360 being the total angle measurement of a circle

270/360 simplifies to 3/4

The fraction represents how much of the circle that arc covers

Now we have to find the circumference which would be

2(3.14)r

r = 2 therefore: 2(3.14)2 = 12.56

Now that we have the circumference of the WHOLE circle we multiply it by 3/4 to find out the arc length

Which gives us 9.42

Given that f(x) = x2 – 3x – 28 and g(x) = x - 7, find

gregori [183]

Answer:

$(f-g)(x)=x^2-4x-21$

Step-by-step explanation:

We are given the two functions:

$f(x)=x^2-3x-28\text{ and } g(x)=x-7$

And we want to find:

$(f-g)(x)$

This is equivalent to:

$=f(x)-g(x)$

Substitute:

$=(x^2-3x-28)-(x-7)$

Distribute:

$=x^2-3x-28-x+7$

Rearrange:

$=(x^2)+(-3x-x)+(-28+7)$

Hence:

$(f-g)(x)=x^2-4x-21$

Which inequality has no solution?<br> 6(x+2) > x-3<br> 3+4x2(1+ 2x)<br> -2(x+6) X-9 <3(x-3)

Juli2301 [7.4K]

Answer:

$6(x + 2) > x - 3$

$6x + 12 > x - 3$

$6x - x > - 12 - 3$

$5x > - 9$

$3 + 4 \times 2(1 + 2x)$

$3 + 8(1 + 2x)$

$3 + 8 + 16x$

$11 + 16x$

$- 2(x + 6)x - 9 < 3(x - 3)$

$- 2( {x}^{2} + 6x) - 9 < 3x - 9$

$- 2 {x}^{2} - 12x - 9 < 3x - 9$
