Answer:

  x ≥[tex]\frac{-5}{2}[/tex]

Step-by-step explanation:

step(i):-

Given inequality

               3x + 7 ≥ x +2

subtracting '2' on both sides, we get

          ⇒ 3x + 7 -2 ≥ x+2-2

         ⇒  3 x + 5 ≥ x

    subtracting 'x' on both sides, we get

           3x +5 -x≥ x-x

       ⇒ 3x +5 -x ≥ 0

      ⇒ 2 x + 5≥ 0

Step(ii):-

subtracting '5' on both sides ,we get

         2 x + 5 -5 ≥ 0-5

   ⇒  2 x ≥ -5

  ⇒  [tex]\frac{2}{2} x\geq \frac{-5}{2}[/tex]

Final answer:-

 ⇒    x ≥[tex]\frac{-5}{2}[/tex]

Answer:

1.05

Step-by-step explanation:

The rate of change of the cost, in dollars, with respect to the number of minutes purchased is 1.05 and this can be determined by differentiating the given function.

Given :

In order to determine the rate of change of the cost, in dollars, with respect to the number of minutes purchased, differentiate the given function with respect to 'x'.

y = 5.45 + 1.05(x + 7)

y = 5.45 + 1.05x + 7.35

y = 12.8 + 1.05x

Now, differentiate the above equation with respect to 'x'.

[tex]\dfrac{dy}{dx} = 0 + 1.05[/tex]

So, the rate of change of the cost, in dollars, with respect to the number of minutes purchased is 1.05.

Answer:

63 days

Step-by-step explanation:

There are seven days would it take for 3 cows.

A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.

Let the required number of days would be x

We have to determine the number of days would it take for 3 cows

As per the given situation, we can write the proportion would be as:

9 cows : 21 days = 3 cows : x days

9/21 = 3/x

Apply the cross-multiplication operation,

9x = 21 × 3

9x = 63

x = 63/9

Apply the division operation, and wet

x = 7

Therefore, the required number of days would be 7 days.

Step-by-step explanation:

If it had 50% of its carbon-14 it would be 5730 years old.

Since it has 65% left it is younger than 5730 years.

So it is (1 - 0.65) * 5730

= 2005.5 years old.

Complete Question:

A closed box has a square base with side length L feet and height h feet. Given that the volume of the box is 39 cubic feet, express the surface area of the box in terms of L only.

Answer:

[tex]A = \frac{156}{L} + 2L^2[/tex]

Step-by-step explanation:

Given

[tex]Volume = 39ft^3[/tex]

Required

Express the surface area in terms of L

Because the box has a square base:

The volume is:

[tex]Volume = Base\ Area * Height[/tex]

Where

[tex]Base\ Area = L * L[/tex]

So, we have:

[tex]Volume = L * L * H[/tex]

Substitute 39 for Volume

[tex]39= L * L * H[/tex]

[tex]39= L^2 * H[/tex]

Make H the subject

[tex]H = \frac{39}{L^2}[/tex]

The surface area (A) of a box with square base is:

[tex]A = 2(LH + LH + L^2)[/tex]

[tex]A = 2(2LH + L^2)[/tex]

Open bracket

[tex]A = 4LH + 2L^2[/tex]

Substitute [tex]\frac{39}{L^2}[/tex] for H

[tex]A = 4L * \frac{39}{L^2} + 2L^2[/tex]

[tex]A = \frac{4L *39}{L^2} + 2L^2[/tex]

[tex]A = \frac{4*39}{L} + 2L^2[/tex]

[tex]A = \frac{156}{L} + 2L^2[/tex]
