\bf \textit{Area of an equilateral triangle}\\\\
A=\cfrac{s^2\sqrt{3}}{4}\qquad 
\begin{cases}
s=\textit{length of one side}\\
----------\\
A=4\sqrt{3}
\end{cases} \implies 4\sqrt{3}=\cfrac{s^2\sqrt{3}}{4}
\\\\\\
\cfrac{4\cdot 4\sqrt{3}}{\sqrt{3}}=s^2\implies \sqrt{\cfrac{4\cdot 4\sqrt{3}}{\sqrt{3}}}=s
\\\\
-----------------------------\\\\

perimeter=s+s+s=3s\impliedby \textit{since all sides are equal}

Question 1
Because the period is 2π, and the amplitude is 1obtain
f(x) = sin(x)
Because the horizontal shift is π, obtain
f(x) = sin(x - π)
Because the vertical shift is -4, obtain
f(x) = sin(x - π) - 4

Answer: 1. f(x) = sin(x - π) - 4

Question 2
The radius is 36/2 = 18 in.
1 revolution (360°) is the circumference, which is
2π(18) = 36π in
When the revolution is 62°, the distance traveled is
(62/360)*(36π) = (31/5)π in

Answer: 3. (31π)/5

Question 3.
Consider f(x) = 3cos(2x-π) - 1
f(0) = 3cos(-π) - 1 = -4
f(π/2) = 3cos(0) - 1 = 2
Rate of change = (2+4)/(π/2) = 12/π

From the graph, the rate of change of g(x)  is
3/(π/2) = 6/π

Consider h(x) = sin(x) - 4
h(0) = 0 - 4 = -4
h(π/2) = 1 - 4 = -3
Rate of change = (-3+4)/(π/2) = 2/π
Therefore h(x) has the smallest rate of change

Answer: h(x)

PLEASEEEEE HELLPPPP ME I NEED HELP ASAPPP I CANNOT FAIL THIS!!!!!!!
Elodia [21]

Answer:

1. Both Dan and Tess are correct.

    Tess:

         0.15 * 24.50 = 3.675

         24.5 - 3.675 = 20.825

         0.1 * 20.825 = 2.0825

         20.825 + 2.0825 = 22.9075

    Dan:

         0.85 * 24.50 =  20.825

         20.825 * 1.1 = 22.9075

    Both Dan and Tess used methods that provided the correct answer. Both methods follow the same path, but Dan's method simply took less steps since he used percentages that would take out the correct number, unlike Tess' percentages which would give you the number that you would then need to take out.

2. First, convert Amy's and Mike's numbers to a decimal of the whole so it is easier to compare the numbers.

    13% = 0.13 of the whole

    Dan has 0.14 of the whole

    0.5/6 = 0.083.. of the whole

Dan used the greatest amount of milk, using 0.14 of the 6 gallon container.

3.

    2p + 12 = 58 | Create an equation to show the prices relations

    2p = 46 | Take out the price of the concert ticket to leave us with the passes.

    p = 23 | Divide by 2 to find the cost of each pass.

4.

    x ≤ (18 - 6.5 - 5.75)/1.15

    18 - 6.50 = 11.5 | Take out the price of the notebook from the total.

    11.5 - 5.75 = 5.75 | Take out the amount of money that she wishes to save.

    5.75 / 1.15 = 5 | Divide by the price of each candy to find the max amount that she can buy.

Andrea has enough money to buy up to 5 candy bars.

You have $9.30 plus 6 percent of tax what is the total costs
mario62 [17]

Answer:

$ 9.86

Step-by-step explanation:

Tax = 6% of 9.30

      = 0.06 * 9.30

     = $ 0.558

Total costs = 9.30 + 0.558

                  = 9.858

                  = $ 9.86

The image above is an example of which type of fossil
Aleksandr [31]

This is an example of fossil preserved in amber.

Amber is a polymerized form of tree resin, produced by the trees so as to protect themselves against diseases and insect pests. This resin hardened and sometimes captured insects, microorganisms, plants, seeds and feathers, spiders, and other small vertebrates that got stuck in the sticky resin.
