Answer:

x = 3; y = 6; z =4

Step-by-step explanation:

The point J is the circumcentre of the triangle.

It is equidistant from the vertices. So

2x + 2 = 8

2x = 6

x = 3

2y - 4 = 8

2y = 12

y = 6

If FI = 9, HI = 9. Then,

3z - 3 = 9

3z = 12

z = 4

So, x = 3; y = 6; z =4.

Average rate of change for f(x) = x2 − 3x − 10 from x = −5 to x = 10.

11111nata11111 [884]

The average rate of change is the slope of the secant line connecting the points on f(x) from x=-5 to x=10.

In other words, it is just the slope of the straight line connecting the points
$(-5,f(-5)) \: and \: (10,f(10))$

So we were given ,

$f(x) = {x}^{2} - 3x - 10$

At
$x = - 5$
$f( - 5) = {( -5 )}^{2} - 3( - 5) - 10$
$f( - 5) = 25 + 15- 10$
$f( - 5) = 30$

Also at
$x = 10$
$f( 10) = {( 10)}^{2} - 3( 10) - 10.$
$f( 10) = 100- 30 - 10$
$f( 10) = 60$

The average rate of change
$= \frac{f(10) - f( - 5)}{10 - - 5}$
$= \frac{60- 30}{15}$
$= \frac{30}{15}$
$= 2$

The sand used for sanding icy roads in the winter is stored in a conical-shaped structure with a radius of 10 m and a height of

pshichka [43]

Answer:

1,675.516

Step-by-step explanation:

The formula for a cone is V = pi r^2 h/3.

Plugging in the values of the radius and height, V = pi 10^2 16/3

Solving, you get:

V = pi 100 5.3333333

V = 1,675.516
