Imagine a new pasture with grass growing on it. Every day after the seeds have germinated, the number of blades of grass in the
Arisa [49]

Answer:

It took 17 days for the pasture to be one-third covered in grass

Step-by-step explanation:

* Lets explain how to solve the problem

- The number of blades of grass is triple every day

- Consider that there are x blades in the first day

∵ The number of blades of grass is triple every day

∴ The next day the number of blades of grass will be 3x

∴ The formula to find the number of blades of grass after d days is

   x(3)^{d}

- After 18 days, the entire pasture is completely covered in grass

∵ d = 18

∴ The number of blades of grass = x(3)^{18}

- We need to know the the number of days that took for the pasture

  to be one-third covered in grass

∵ The number of blades of grass for 1/3 covered = (\frac{1}{3})x(3)^{18}

∴ (\frac{1}{3})x(3)^{18}=x(3)^{d}

- Remember  \frac{1}{3}=3^{-1}

∴ 3^{-1}x(3)^{18}=x(3)^{d}

- Remember we add the power of the same bases when we

 multiply them

∴ x(3)^{-1+18}=x(3)^{d} ⇒ divide both sides by x

∴ (3)^{17}=(3)^{d}

- Remember if the two bases equal in the equation, then their

 powers are equal

∴ d = 17

* It took 17 days for the pasture to be one-third covered in grass

What is the length of the shorter base of the Little Trapezoid trail?
valentina_108 [34]

Answer:

The length of the shorter base of the little trapezoid trail is 1 mi.

Step-by-step explanation:

Let the shorter base of the large trapezoid is S and the larger base of the large trapezoid is L.

Similarly, assume that the shorter base of the small trapezoid is s and the larger base of the small trapezoid is l.

Since, the trapezoids are similar, so

\frac{L}{l} = \frac{S}{s}

Now, given that S = 2 mi, L = 8 mi and l = 4 mi and we have to find s.

So, s = \frac{S \times l}{L} = \frac{4 \times 2}{8} = 1 mi. (Answer)

What is the inverse of the function f(x) = x - 12?
ludmilkaskok [199]

Answer: \displaystyle f(x)^{-1}=x+12

Step-by-step explanation:

     First, we will rewrite the function in terms of <em>y</em> as in y = x - 12.

     Second, we will swap the x and y values.

y = x - 12

x = y - 12

     Third, we will solve for y. In other words, we will isolate the <em>y</em> variable and get it "by itself" on one side of the equal sign.

x = y - 12

x + 12 = y

y = x + 12

      Lastly, we will change y back into terms of the function, but the inverse.

\displaystyle f(x)^{-1}=x+12
