Suppose the production cost is R1895, labour cost is and equipment renting fee is R 250, determine the number of devices produced

A jewellery store sells bead necklaces. Each necklace costs R40 for the wire and R15 per bead. There exists a linear relationship between the cost of the necklace and the number of beads the necklace has. The cost, C, is dependent on the number of beads, n. The graph that represents this relationship correctly is [1] C n 340 40 20 [2] C n 335 8 [3] C n 340 20 [4] C n

Let T : R4--> R4 be the linear transfoi-mation

defined by

T(x1, X2, X3, X4) = (— x2, X1, — x4, X3).

Check that T4 = I. Also, find the minimal

polynomial of T.

Suppose the production cost is R293 250 , computing components cost is R1035 , labour costs is R4140 and the savings on reusable material is R1725, what is the number of devices produced?

Solve the following problems:

1. Jane and Albert bought a farm

measuring 78 3/5meters on one side, 63 7/10 meters on the second side, 132 5/9 meters on the third side, and 130 1/4 meters on the fourth side. The couple wants to fence the farm

with barbed wire. They have 2 rolls of barbed wire of 500 meters per roll on

hand. How many more meters of barbed wire would they have to buy if they want

to fence the farm four times?

2. Gabriela, Corazon and Remedios formed a partnership. Gabriela

contributed 1/2 of the capital. Corazon contributed 1/4 of what Gabriela contributed. Remedios contributed the remainder.

a. How much more did Gabriela

contribute than Corazon? Remedios?

b. Show the capital contributions

of the partners in terms of fractional parts.

c. Prove your answer in (b) using

subtraction.

d. If the total capitalization of

the partnership was 30 000.00, how much did each of the partners contribute?

suppose the production cost is R18 925, labour cost is R1245 and equipment renting fee of R250, determine the number of devices produced

Find the quadratic equation whose roots are -2/3 and -1/4

The production cost, represented by y, of smart phone devices are equal to the product of computing components a and the square of the number of devices x, added to the product pf labour b and number of devices x; after which savings on reusable material c are subtracted.

2.1. Suppose the production cost is R 239250, computing components cost is R1035, labour cost is R4140 and the savings on reusable materials is R1725, determine the number of devices produced

2.2. Hence, write down the equation with y as subject (in terms of x) to represent the production cost.( the value of a, b and c must be indicated.

The production cost ,represented by Y,of a bluetooth device ,is equal to the product of labour cost (m)and number of devices (x)in addition to a constant equipment renting fee(q)
