The table represents a quadratic function that shows how a company's cost to manufacture an item depends on the total number of

items produced.
#of Items|Cost per item ($)
0|154
100|135
200|118
300|103
400| 90
500| 79
600| 70
700| 63
800| 58
900| 55
1000| 54
1100| 55
1200| 58

The y-intercept represents

[i] A.) the cost to the manufacturer of not producing any items[/i]

[i] B.) the cost per item to the manufacturer when it manufactures 600 items [/i]

[i]C.) the cost per item to the manufacturer when revenue is equal to cost [/i]

Looking at the given values, we can answer the questions
The cost for not producing any items is $154
The cost per item when the number of items manufactured is 600 is $70
The cost per item when the revenue is equal to the cost is $54<span />

Trigonometry, can anybody help??
WINSTONCH [101]

Answer:

angle B: 39

AC: 7.288

AB: 11.58

(note: you cut off the part about rounding so make sure that it's rounded correctly before you put in your answer)

Step-by-step explanation:

To solve this we will use SOH, CAH, TOA

we have the angle and the one opposite to it which means we can use either SOH or TOA

let's use TOA

tan(51)=(9/x)

x= 7.288

We can now use pahtagaryous theroem to solve for the hyptonouse

we have

9²+7.288²=C²

C=11.58

Finally, to find angle B we will recall that the angles of a triangle must add to 180.

51+90+a=180

a=39

Which must be true of a quadratic function whose vertex is the same as its y-intercept?
BaLLatris [955]

Answer:  Choice A

The axis of symmetry for the function is x = 0.

===========================================================

Explanation:

The vertex is on the axis of symmetry. Since the vertex is on the y axis, this means the y axis itself is the axis of symmetry. The y axis is represented by the equation x = 0. Every point on the y axis has an x coordinate of 0. Example points are (0,2) and (0,5).

This parabola may have 0 roots, 1 root, or 2 roots.

The sum of two numbers is 53. If their difference is 25 find both numbers.
timama [110]

Answer:

x=39

y=14

Step-by-step explanation:

x+y=53...(1)

x-y=25...(2)

(1)+(2): 2x==78

x=78/2

x=39

then

x+y=53

39+y=53

y=53-39

y=14
