Answer: He will need 20 feet of fabric .

Step-by-step explanation:

Given: circumference of cushion =  7.85 feet.

Since , circumference = 2\pi r , where r = radius.

\Rightarrow\ 2\times3.14\times r=7.85\\\\\Rightarrow\ r=\dfrac{7.85}{6.28}\\\\\Rightarrow\ r=1.25

Area of each piece = \pi r^2

=3.14\times(1.25)^2=4.90625$\approx5\text{ feet}

Area of 2 pieces = 2 x 5 feet = 10 feet

Area for 2 cushions = 2 x (Area of 2 pieces)

= 2 x 10 feet = 20 feet

He will need 20 feet of fabric .

Answer:  g = -4  and   h =1     or   g= -1  and h = -2

Step-by-step explanation:

If two exponents have the same base and are multiplied together,  you will keep the base unchange and add the exponents.  

So looking at the equation, the base is 2 for both and they are raised to the powers  g and h, meaning that if  g and h are added together they have  to equal -3.

So find two numbers that their sum is -3.

For example,  -1 and -2 add up to -3, -4 and 1 add up to -3.

Write an equation of the form y=a sin bx or y= a cos bx to describe the graph below.
kakasveta [241]

we conclude that the graphed equation is:

y = 4*cos(pi*x)

<h3></h3><h3>Which trigonometric equation is the one in the graph?</h3>

First, we can see that the graphed function is even, so we know that it wiill be a cosine.

We also can see that the maximum is 4 and the minimum is -4, so the amplitude is 4.

Then we have something like:

y = 4*cos(b*x)

To find the value of b, we can use the fact that the zeros of the function are at x = ±1/2

Then:

b*1/2 = pi/2

b = pi

Finally, we conclude that the graphed equation is:

y = 4*cos(pi*x)

A woodworker makes wooden checkerboards. her profit is a function of the price she charges. this graph shows her total profits,
pantera1 [17]

Answer:

Option B.

Step-by-step explanation:

Remember that the profit is defined as the difference between the revenue and the cost.

So, having a profit y = 0 means that the woodworker did not win nor lose anything.

Then the zeros of the function, the values of x such that the graph intersects the x-axis, are the prices such that she does not win nor loss anything.

In the graph we can see that the zeros are at:

x = 15 (the first one)

x = 70 (the second one)

so the zeros are at x = 15 and x = 70, and these are the prices such that the profit is zero, so at these prices she does not make nor lose money.

The correct option is B.
