The function f(x)=43x+320 gives the function from selling x items. What is the average profit per item if 123 items are sold?

____ [38]

Profit of x items =43x + 320

Profit of 123 items = 43(123) + 320

= 5289 + 320

= 5609

Average profit = 5609/123

= 45.6

Hence, average profit = 45.6.

The angle of elevation from a ship to the top of a light-house is 3 degrees, if the ship is 1000 meters from the light-house how

Mashutka [201]

Tangent 3 degrees = height / 1,000
height = tangent (3) * 1,000
height = 0.052408 * 1,000
height = 52.408 meters

The endpoints of the directed line segment AB are A(-1 2) and B (7 8). Find the coordinates of point P along AB so that the rati

san4es73 [151]

Answer:

The coordinates of P are (1,3.5)

Step-by-step explanation:

Here, we simply want to find the coordinates of point P that divides line AB in the ratio 1 to 3

Mathematically, that would be;

(x,y) = (nx1 + mx2)/(m + n) , (ny1 + my2)/(m + n)

where in this case m = 1, n = 3

(x1,y1) = (-1,2)

(x2,y2) = (7,8)

Thus, we have ;

(x,y) = (3(-1) + 1(7)/)1+3) , (3)2) + 1(8)/(1 + 3)

(x,y) = (-3+7)/4 , (6 + 8)/4

(x,y) = 4/4, 14/4

(x,y) = (1,3.5)

2. The cone has a radius of 30 mm and slant height of 34 mm. What is the height h for this cone?

Flura [38]

Answer:

h = 16

Step-by-step explanation:

By applying the Pythagorean Theorem, the slant height is given by the formula:

$\sqrt{r^2+h^2}$

34 = $\sqrt{30^2 + h^2}$

$34^2 = 30^2 + h^2$

$1156 = 900 + h^2$

$256 = h^2$

$h = \sqrt{256}$

$h = 16$
