find the area of each figure in square units. show your work and explain how you got the answer.​

Answer:

471.24

Step-by-step explanation:

The formula for circumference is 2×pi×r. Replace the r with 75 and multiply.

circumference of the race track = 471.24 yards.

A circle is a two-dimensional figure formed by a set of points that are at a constant or at a fixed distance (radius) from a fixed point (center) on the plane. The fixed point is called the origin or center of the circle and the fixed distance of the points from the origin is called the radius.

Given,

radius of race track r = 75  yards

circumference of the park = 2πr

                                            = 2×3.1416×75

                                            = 471.24 yards

471.24 yards is the circumference of the race track.

Answer:

Using EMV analysis, the number of units of the new product should be purchased for resale = Purchase 7.

The maximum EMV of profit you can make is 270.

Explanation:

We can use the following method to solve the given problem

Solution:

Using EMV analysis,

EMV (Purchase 6 for resale)= 6(40)(0.1) + 6(40)(0.4) + 6(40)(0.5)=240

EMV (Purchase 7 for resale) = [6(40)-60](0.1) +7(40)(0.4) + 7 (40)(0.5) = 270

EMV (Purchase 8 for resale) = [6(40)-2(60)] (0.1) + [7 (40) - 60] (0.4) + 8(40)(0.5)= 260

Largest EMV= 270; Choose to purchase 7 units for resale.

Answer:

0

Step-by-step explanation:

when f(x) is divided by (x - h) then the remainder is f(h)

f(x) = x³ - 9x² + 6x + 2 with h = 1 , then

f(1) = 1³ - 9(1)² + 6(1) + 2 = 1  - 9 + 6 + 2 = 0

since the remainder is 0 then (x - 1) is a factor of f(x)

Using relations in a right triangle, it is found that the length of AC is of 6.43 inches.

The relations in a right triangle are given as follows:

In this problem, the length of side AC is b, which is opposite to the angle of 40º, while the hypotenuse is of 10 in, hence:

[tex]\sin{40^\circ} = \frac{b}{10}[/tex]

[tex]b = 10 \times \sin{40^\circ}[/tex]

Using a calculator:

[tex]b = 6.43[/tex]

Answer:

y = 3x - 6 [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

We can use y = m x + c to find the equation of the line.

Here,

m ⇒ slope

c ⇒ y - intercept

They have already given the slope of the line.

m = 3

And now we have to find the y - intercept using the given coordinates.

( 2 , - 1/2 ) ⇒ ( x , y )

Let us find now.

y = m x + c

-1/2 = 3 × 2 + c

-0.5 = 6 + c

-0.5 - 6 = c

-6.5 = c

-6 1/2 = c

Now let us write the equation of the line.

y = m x + c

y = 3x - 6 [tex]\frac{1}{2}[/tex]

Answer:

f(x)= -1(x-3)(x+4)

First blank: -1

2nd blank: 3

3rd blank: 4

Step-by-step explanation:

When the parabola is flipped upside down (opened downward) there should be a negative in front. So the first blank is -1. Also, this parabola has not been stretched or smashed, that's why the value is a 1. Again, negative, because its reflected (flipped).

The other two blanks will come from the x-intercepts. The curve crosses the x-axis at 3 and -4.

If x = 3, then

subtracting 3 from both sides

x - 3 = 0

That x-3 is the

x - blank in the problem. Fill in a 3.

If x = -4, then adding 4 to both sides,

x + 4 = 0

Likewise, this x+4 is the

x + blank

in the question. Fill in a 4.
