The measure of an angle is 11.3°. What is the measure of its supplementary angle?

Answer:

x = 1 ± [tex]\sqrt{5}[/tex]

Step-by-step explanation:

x(x - 2) = 4

Multiply x on the left side by foil.

[tex]x^{2}- 2x = 4[/tex]

Subtract 4 on both sides.

[tex]x^{2} -2x-4=0[/tex]

Now, the quadratic formula.

x = (-b ± [tex]\sqrt{b^{2} - 4ac }[/tex]) / 2a

Using the standard form equation.

Ax² + Bx + C = 0

(1)x² - 2x - 4 = 0

A = 1

B = -2

C = -4

x = (-(-2) ± [tex]\sqrt{(-2)^{2}-4(1)(-4) }[/tex]) / 2(1)

x = (2 ±[tex]\sqrt{4+16}[/tex] ) / 2

x = (2±[tex]\sqrt{20}[/tex])/2

x = (2±2[tex]\sqrt{5}[/tex])/2

x = 1 ± [tex]\sqrt{5}[/tex]

Answer:

5x^3 + 7

Step-by-step explanation:

So basically a binomial is when there are 2 terms

To a certain degree (it's 3 in this case) is when the variable is to that power.

For example: [tex]5x^{3} + 7[/tex]

Answer:

Let x = # of hot dogs sold

Let x + 31 = # of sodas sold

For the total, do:  x + x + 31 = 173

                         2x + 31 = 173

                               -31     -31

                         2x            = 142

  Divide out both sides by 2; to get:  x - 71

  That gives us 71 hot dogs; and 71 + 31 = 102 sodas

  To test this:  71 + 71 + 31 = 173

                                173    =  173    [Check]

Hence

A) The computation of the break-even point in units for Green Meadows, which makes three types of portable coolers, can be determined using the following break-even formula:

= Fixed costs/Weighted contribution margin per unit

                                Model X100     Model X950       Model X800

=                              3,000 units          771 units           1,350 units

              (1,080,000/$360)  (1,080,000/1,400)    (1,080,000/800)

B) The computation of the break-even point in pesos for Green Meadows, which makes three types of portable coolers, can be determined using the following break-even formula:

= Fixed costs/Weighted contribution margin per unit

                       Model X100              Model X950         Model X800

=               240 million pesos      11,416,490 pesos      32,432,432 pesos

              (1,080,000/0.45%)  (1,080,000/9.46%)    (1,080,000/3.33%)

C) If Green Meadows has a target profit of 1M, the number of units of each type of cooler that must be sold is determined using the following break-even formula:

= Fixed costs + Target Profit /Weighted contribution margin per unit

                                Model X100     Model X950            Model X800

=                               5,778 units       1,486 units             2,600 units

                    (2,080,000/$360)  (2,080,000/1,400)    (2,080,000/800)

The break-even analysis is an accounting technique used to determine the break-even point.

The break-even point shows the units or dollars that must be achieved so that the total revenue equals the total costs, both variable and fixed.

Fixed cost = 1,080,000 pesos

Answer:

∠ ABC = 79°

Step-by-step explanation:

the measure of the inscribed angle ABC is half the measure of its intercepted arc AC

the sum of the arcs on the circle = 360° then

arc AC = 360° - 94° - 108° = 360° - 202° = 158° , then

∠ ABC = [tex]\frac{1}{2}[/tex] × 158° = 79°

Answer:

#1

Well lets solve the polynomial first.

(4p +3) ^2

That is basically

(4p + 3) (4p + 3)

And we’re trying to find the error in the “equal” solution.

16p^2 + 8p + 9.

So let’s solve the polynomial first

Following F.O.I.L

F- First

O- Outter

I- Inner

L- Last

So doing the equation in order.

4p * 4p = 16p^2

4p * 3 = 12p

3 * 4p = 12p

3* 3 = 9

Added it all up.

16p^2 + 12p + 12p + 9

Simplify.

16p^2 +24p +9
We can see that in this case the 8p is wrong.

So we replace 8p with 24p

In this case the last option.

Factoring #2

So we’re factoring

9x^2 -6x - 3

So how are we gonna do this.

So I’m just gonna go over the simple method.

The standard form of a quadratic is

Ax^2 + bx + c = 0

We don’t have to worry about the equal 0 part here for now.

ax^2 + bx + c

A being the number next to x^2

B is the number being next to x

C is the number that is next to nothing, jsut a plain whole number (sometimes whole number)

So let’s plug it in.

(It’s already plugged in so we can solve)

9x^2 - 6x - 3

Multiply a and c in ths case being, 9 and -3.

You’d get -27

We need two numbers that multiply to -27 and add up to -6

From here it’s guessing and checking.

Here’s my process.

trial 1

Since the sum is negative, it has to be negative + negative or positive + negative greater then the positive. Or vice versa but positive is less then negative.

But the product has to be -27,negative * negtaive is positive, so it has to be positive * negative and positive + negative.

I look at -27 and think of two numbers that would give the lowest.

-9 * 3

-9 * 3 = -27

-9 + 3 = -6

It looks like I got it already on the first try.

The numbers are -9 and 3

end of trial 1

So now I know that the numbers are -9 and 3.

Using that information I just plug it into the quadratic but replace it with b.

9x^2 -9x + 3x - 3

Now you can simplify this

In the end you’d get

3 (3x+1)(x-1)

You’d have the third option open to you

Figure out the second one using these strategies

The slopes -2/3 and 3/2 multiply to -1, which is sufficient info that the lines are perpendicular. Perpendicular slopes always multiply to -1 assuming neither line is vertical nor horizontal.

Note how -2/3 is the negative reciprocal of 3/2, and vice versa.

Answer:

perpendicular

perpendicular lines have slopes that are negative reciprocals of one another. if a slope of a line was 5, then the slope of a line perpendicular to it would be -1/5, for example.

When the sides are the same then the triangles are congruent.

Identical lines through the sides of a triangle indicate that the sides are congruent.

Congruent triangles are those that are exactly the same size and shape. Congruent is represented by the symbol ≅ When the three sides and three angles of one triangle match the dimensions of the three sides and three angles of another triangle, they are said to be congruent.

Congruent triangles are two triangles that are identical in terms of size and shape. One of two congruent triangles remains congruent even if it is rotated, flipped, or turned. Two triangles must have the same sides in order for them to have the same angles and, as a result, to be congruent.

Thus, identical lines through the sides of a triangle indicate that the sides are congruent.

Answer:

The second graph is the answer

The area of the lane is 50 in² and its perimeter is 30 in.

Area is the amount of space occupied by a two dimensional object or figure. For a rectangle:

Area = length * width

Let the length of the lane be 10 in and the width be 5 in, hence:

Area = 10 * 5 = 50 in²

Perimeter = 2(length + width) = 2(10 + 5) = 30 in

The area of the lane is 50 in² and its perimeter is 30 in.
