The rate of change for the interval between 2 and 6 on the x-axis is 3.

Given

On a coordinate plane, a parabola opens up.

Solid circles appear on the parabola at (negative 4, 14), (negative 3, 9. 5), (negative 2, 6), (0, 2), (1, 1. 5), (2, 2), (4, 6), (5, 9. 5), (6, 14).

A rate of change defines how one quantity changes in relation to another quantity.

The rate of change for the interval between 2 and 6 on the x-axis is;

[tex]\rm Rate \ of \ change =\dfrac{2-14}{2-6}\\\\Rate \ of \ change =\dfrac{-12}{-4}\\\\Rate \ of \ change =3[/tex]

Hence, the rate of change for the interval between 2 and 6 on the x-axis is 3.

Then you subtract 4 from 29 and get 25. Then divide 25 by 0.75 and you get the answer 33.3333333333. Round it to the nearest whole number and you get the final answer of 33 braids.

Answer:

B) 59 in²

Step-by-step explanation:

From inspection of the diagram, we can see that the polygon is made up of one rectangle and two triangles.

Area of a rectangle = width × length

Given:

⇒ area = 4 × 7 = 28 in²

Area of a triangle = 1/2 × base × height

Given:

⇒ area = 1/2 × 7 × 6 = 21 in²

Area of a triangle = 1/2 × base × height

Given:

⇒ area = 1/2 × 4 × 5 = 10 in²

Total area = 28 + 21 + 10 = 59 in²

The quadratic equation 2x² + 12x – 3 = 0 can be written as 2(x²+12x+9)=3+18. Then the correct option is A.

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

Inga is solving the quadratic equation 2x² + 12x – 3 = 0

   2x² + 12x – 3 = 0

        2x² + 12x  = 3

 2x² + 12x + 18 = 3 + 18

2 (x² + 12x + 9) = 3 + 18

The quadratic equation 2x² + 12x – 3 = 0 can be written as 2 (x² + 12x + 9) = 3 + 18. Then the correct option is A.

Answer:

a) x = 6°  b) m∠B = 50°

Explanation:

(a) total angle measure of a triangle is 180°

8x + 2 + 70° + 60° = 180°

8x + 132° = 180°

8x = 180° - 132°

8x = 48°

x = 6°

(b)

m∠B = 8x + 2

m∠B = 8(6) + 2°

m∠B = 48° + 2°

m∠B = 50°

Answer:

A. X is 6 and B. Angle is 50

Step-by-step explanation:

PART A

Triangle sum theorem explains that all angles in a triangle add up to 180

(8x + 2) + 70 + 60 = 180

8x= 180-70-60-2

8x= 48

X= 48/8 =6

PART B

Using the formula provided, replace the x with 6

So it'll be 8(6)+2 = 48+2 = 50

The equation of the circle in squared form is [tex]\rm (x + 6)^2 + (y + 1)^2 = 38[/tex]. Then the center of the circle is at (-6, -1).

It is a locus of a point drawn at an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

The equation of the circle is given as

[tex]\rm x^{2} + y^2 + 12x +2y - 1 = 0[/tex]

This can be written as

[tex]\rm x^{2} + y^2 + 12x +2y = 1[/tex]

Add both sides 36 and 1, then

[tex]\rm x^{2} + 12x + 36 + y^2 +2y +1 = 1 + 36 + 1[/tex]

Then we know that

[tex]\rm (a+b) ^2 = a^2 + b^2 + 2ab[/tex]

Then

[tex]\rm (x + 6)^2 + (y + 1)^2 = 38[/tex]

Thus, the center of the circle is at (-6, -1).

Answer(s):

[tex]\displaystyle y = 3cos\:(2\pi{x} - \frac{\pi}{2}) + 3 \\ y = -3sin\:(2\pi{x} \pm \pi) + 3 \\ y = 3sin\:2\pi{x} + 3[/tex]

Step-by-step explanation:

[tex]\displaystyle y = Acos(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow 3 \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \hookrightarrow \boxed{\frac{1}{4}} \hookrightarrow \frac{\frac{\pi}{2}}{2\pi} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{1} \hookrightarrow \frac{2}{2\pi}\pi \\ Amplitude \hookrightarrow 3[/tex]

OR

[tex]\displaystyle y = Asin(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow 3 \\ Horisontal\:[Phase]\:Shift \hookrightarrow 0 \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{1} \hookrightarrow \frac{2}{2\pi}\pi \\ Amplitude \hookrightarrow 3[/tex]

You will need the above information to help you interpret the graph. First off, keep in mind that although this looks EXACTLY like the sine graph, if you plan on writing your equation as a function of cosine, then there WILL be a horisontal shift, meaning that a C-term will be involved. As you can see, the photograph on the right displays the trigonometric graph of [tex]\displaystyle y = 3cos\:2\pi{x} + 3,[/tex] in which you need to replase "sine" with "cosine", then figure out the appropriate C-term that will make the graph horisontally shift and map onto the sine graph [photograph on the left], accourding to the horisontal shift formula above. Also keep in mind that the −C gives you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so you must be careful with your calculations. So, between the two photographs, we can tell that the cosine graph [photograph on the right] is shifted [tex]\displaystyle \frac{1}{4}\:unit[/tex]to the left, which means that in order to match the sine graph [photograph on the left], we need to shift the graph FORWARD [tex]\displaystyle \frac{1}{4}\:unit,[/tex]which means the C-term will be positive, and by perfourming your calculations, you will arrive at [tex]\displaystyle \boxed{\frac{1}{4}} = \frac{\frac{\pi}{2}}{2\pi}.[/tex]So, the cosine graph of the sine graph, accourding to the horisontal shift, is [tex]\displaystyle y = 3cos\:(2\pi{x} - \frac{\pi}{2}) + 3.[/tex]Now, with all that being said, in this case, sinse you ONLY have a graph to wourk with, you MUST figure the period out by using wavelengths. So, looking at where the graph hits [tex]\displaystyle [-\frac{1}{4}, 0],[/tex]from there to [tex]\displaystyle [\frac{3}{4}, 0],[/tex]they are obviously [tex]\displaystyle 1\:unit[/tex]apart, telling you that the period of the graph is [tex]\displaystyle 1.[/tex]Now, the amplitude is obvious to figure out because it is the A-term, but of cource, if you want to be certain it is the amplitude, look at the graph to see how low and high each crest extends beyond the midline. The midline is the centre of your graph, also known as the vertical shift, which in this case the centre is at [tex]\displaystyle y = 3,[/tex]in which each crest is extended three units beyond the midline, hence, your amplitude. So, no matter how far the graph shifts vertically, the midline will ALWAYS follow.

Since the opposite side of the quadarilateral are equal hence it is a rectangle.

The sum of the external side is equal to the perimeter. The perimeter of the shape is expressed as:

P = 2(l+w)

where:

P = 120cm

If the width is 30cm less than twice it’s length, then;

w = 2l + 30

Substitute

120 = 2(l + 2l + 30)
60 = 3l + 30
3l = 30
l = 10

The sheet used by Mario and Patience which is going to warm up the quickest, and, therefore, bake the cookies the fastest is copper sheet.

The specific heat of a substance is the amount of heat needed, to raise the temperature of the of one gram of substance by unit degree Celsius.

The specific heat capacity of the substance can be given as,

[tex]C=\dfrac{Q}{m\Delta T}[/tex]

Here, (m) is the mass of the substance, (Q) is heat energy and

is the change in temperature.

The above formula can be rewritten as,

[tex]{Q}={m\Delta T}C[/tex]

By this formula, we can say that the heat energy is directly proportional to the specific heat of the substance.

Thus the value of heat energy required to warm up the substance will be higher with the higher value of specific heat and result of it the substance require more time to warm up.

Here, the specific heats of these substances are:

Treated glass = 0. 75 J/g • °C

Aluminum = 0. 90 J/g • °C

Stainless steel = 0. 50 J/g • °C

Copper = 0. 39 J/g • °C
