The total cost, in dollars, to order x units of a certain product is modeled by C(x)=5x²+320 . According to the model, for what
lora16 [44]

Answer:

The minimum cost per unit is obtained for an order of 8 units.

Step-by-step explanation:

Since the total cost is modeled by;

C(x)=5x²+320

Then;

1 unit costs; C(x)=5(1)²+320 = 325

cost per unit 325/1 = 325

8 units costs; C(x)=5(8)²+320 = 640

cost per unit = 640/8 = 80

80 units costs; C(x)=5(80)²+320 = 32320

Cost per unit = 32320/80 = 404

The minimum cost per unit is obtained for an order of 8 units.

Use the formula for interest P=750 r=7% Y=25 A=?
Over [174]

Answer:

2062.50

Step-by-step explanation:

Interest = (Principle x rate x time)/100

Amount = Principle + interest

Principle = 750

Rate = 7%

Time = 25 years

(750 x 7 x 25)/100

= 131250/100

=1312.50

Principle = 750

Interest = 1312.50

Amount = 750 + 1312.50

Amount = 2062.50

What are the answers plz help me
Serga [27]

For number 3 it would be |-10| and |10|.

Number 5a is supposed to <, because -1 is greater than -7 when you look at the line graph. The same goes for 5b. 5d is >, because 0 is always greater than -1 and it shows that on the line graph that you have there. 5e is =.

I don't see anything else wrong though. Just the ones I listed.

Hope that helps!
