A plant that manufactures metal plates has a quality control team to check that the plates are the right size. A rectangular pla
Kamila [148]

Answer:

Given the size of rectangular plate in advertisement = 5 cm by 3cm.

Given the condition for length should be   = 0.25 of 5 cm  

Step-by-step explanation:

Now, have to write the inequality from the given data.

Therefore,  5- 0.25 ≤ L ≤ 5+.25

4.75 ≤ L ≤ 5.25

We know that the area of a rectangle =  Length × Width.

 Width = 3

Thus, the area is 3 × L

3× (4.75) ≤ 3×L ≤3× (5.25)

14.25 ≤ 3×L ≤ 15.75

So the minimum area is 14.25 cm^2

The maximum area is 15.75 cm^2

How do you factor the sum of 2 squares?
Kazeer [188]
<span>If two terms in a binomial are perfect squares separated by subtraction, then you canfactor them. To factor the difference of two perfect squares, remember this rule: if subtraction separates two squared terms, then the sum and the difference of the twosquare roots factor the binomial.</span>

SUppose the total cost C(x) to manufacture a quantity x of insecticide (in hundreds of liters) is given by
Hitman42 [59]

Answer:

a) C(x) is increasing in two regions: (i) (+\infty, 8\,s) and (ii) (10\,s,+\infty).

b) C(x) decreases in (8\,s, 10\,s).

Step-by-step explanation:

Let C(x) = x^{3}-27\cdot x^{2}+240\cdot x +850, where x is the quantity of insecticide, measured in hundreds of liters, and C(x) is the total manufacturing cost as a function of the quantity of the insecticide, measured in US dollars. A possible approach to determine which regions of C(x) are decreasing and increasing by means of the first derivative and graphing tools. The first derivative of the function is:

C'(x) = 3\cdot x^{2}-54\cdot x+240 (1)

Please notice that regions where C(x) is increasing has C'(x) > 0, whereas C'(x) < 0 when C(x) < 0.

We notice that C(x) is increasing in two regions: (i) (+\infty, 8\,s) and (ii) (10\,s,+\infty). Besides, C(x) decreases in (8\,s, 10\,s).

PLEASE HELP! What is the value of x in the equation below?
Svetlanka [38]

Answer:

C. 20

Step-by-step explanation:

We have to isolate x.

6(x - 8) = 72

Distribute 6.

6x - 48 = 72

Add 48 to both sides.

6x = 120

Divide both sides by 6.

x = 20
