Find the value of x.

Mathematics
1 answer:
ElenaW [278]2 years ago
7 0

Answer:

x = 3

Step-by-step explanation:

Given 2 intersecting chords, then

The product of the parts of one chord is equal to the product of the parts of the other chord, that is

5x × x = 5 × 9

5x² = 45 ( divide both sides by 5 )

x² = 9 ( take the square root of both sides )

x = \sqrt{9} = 3

Find the y-intercept of the line -4× - 2y =16​
Oksi-84 [34.3K]

Answer:

The y intercept is (0,-8)

Step-by-step explanation:

To find the y intercept, set x = 0 and solve for y

-4x -2y = 16

-4(0) -2y =16

-2y = 16

Divide by -2

-2y/-2 = 16/-2

y = -8

The y intercept is (0,-8)

Suppose a computer manufacturer has the total cost function
S_A_V [24]

Answer:

(a)  P(x) = 300 x - 3600

(b)  P(340) = $ 98400

(c)  At least 12 items must be sold to avoid losing money.

Step-by-step explanation:

Part (a):

The Profit function is the difference between the revenue function (R(x)) and the Cost (C(x)) function:

P(x) = R(x) - C(x)

P(x) = 384 x - [84 x + 3600]

P(x) = 384 x - 84 x - 3600

P(x) = 300 x - 3600

Part (b):

The profit on 340 items is:

P(340) = 300 (340) - 3600

P(340) = 102000 - 3600

P(340) = $ 98400

Part (c):

To avoid losing money, the profit P(x) has to be larger or equal than zero. That is:

P(x) \geq 0

300 x -3600  \geq 0

300 x  \geq 3600

x  \geq 3600/300

x  \geq 12

So at least 12 items must be sold to avoid losing money.
