f(x) =  {x}^{2}  - 2x

0 =  {x}^{2}  - 2x

{x}^{2}  - 2x = 0

Factor x

x(x - 2) = 0

x = 0 \:  \:  \: or \:  \:  \: x - 2 = 0

x = 0 \:  \:  \:  \: or \:  \:  \:  \: x = 2

These are the zeroes.

14 ) Go...

f(x) =  {x}^{3}  + 9x + 11x - 21

0 =  {x}^{3}  + 9 {x}^{2}  + 11x - 21

{x}^{3}  + 9 {x}^{2}  + 11x - 21 = 0

(x - 1)(x + 3)(x + 7) = 0

x - 1 = 0 \:  \: or \:  \: x + 3 = 0 \:  \: or \:  \: x + 7 = 0 \\

. Un turist a parcurs un traseu în trei zile. În prima zi turistul a parcurs
Dahasolnce [82]

Answer:

The total length of route travelled in 3 days = 30 km

Lungimea traseului parcurs în cele trei zile = 30 km

Step-by-step explanation:

English Translation of the Question

A tourist traveled a route in three days. On the first day the tourist covered 40% of the length of the route, on the second day the tourist covered 5/6 of the remaining distance after the first day, and on the third day the remaining 3 km. Calculate the length of the route traveled in the three days.

Let the total length of the route be x.

Lungimea traseului parcurs în cele trei zile = x

- On the first day, the tourist covers 40% of the total length of the route;

În prima zi turistul a parcurs 40% din lungimea traseului

That is, 40% of x = 0.4x

- On the second day, the tourist covered 5/6 of the remaining journey.

în a doua zi turistul a parcurs 5/6 din distanța rămasă de parcurs după prima zi

The remaining journey after day 1 = x - 0.4x = 0.6x

(5/6) of the remaining journey = (5/6) × 0.6x = 0.5x

- On the third day, the toursit travels the total remaining length of the route = 3 km

iar în a treia zi restul de 3 km

The total remaining length of the route = x - 0.4x - 0.5x = 0.1x

0.1x = 3

x = (3/0.1) = 30 km

The Hope this Helps!!!

A new piece of laboratory equipment costing $10,000 promises to save $4000 per year in materials and overtime pay. If the cost o
devlian [24]

Answer:

YES, the equipment should be purchased

Step-by-step explanation:

You borrow $10000 for the piece of laboratory and the cost of money is 12%. After 3 years you will need to pay the $10000 you borrowed and the extra amount caused by the interest. 12% of $10000 if $1200, so you will end up having to pay $10000+$1200 = $11200. In three years your equipment saves you $4000*3 = $12000, which is bigger than the amount you have to pay. So, in the end the equipment should be purchased because it gives you a gain of $800.
