Answer:

1. a= 1

  b=10

   c=9

2.y=1/2x-1

3. a) y=3x + 0

   b) y=2x+3

   c)3

   d) $9

Step-by-step explanation:

1.   The values in the x-axis increase by 2 hence a=3-2=1  and c=7+2=9. For the y-values, they increase by 1.

2. The equation of the line can be written in the slope form of y=mx+c where m is the gradient of the line and c is the y-intercept

Taking points on the line ; (-2,-2) and (2,0) the gradient m is ;

m=Δy/Δx  Δy=0--2=2  Δx=2--2=4   m=2/4⇒1/2

From the graph c= -1

The equation y=1/2x-1

(a) Equation representing Layla fees is;

   Taking points (1,3)  and (2,6)  the gradients is

   m=Δy/Δx   (6-3)/(2-1) = 3/1 =3

    Taking m=3, point (1,3) and (x,y) the equation will be;

    m=Δy/Δx

     3=y-3/x-1  

    3(x-1) = y-3

     3x-3 = y-3

     3x-3+3=y

      y=3x + 0 ------equation for Layla line

(b) Equation representing Sam line for fees is

     Taking points (1,5) and (2,7) where c=3

      m=Δy/Δx

      m=7-5/2-1

      m=2/1 =2

     Equation : y=2x+3

Answer:

Step-by-step explanation:

The value of the angle ∠VUW is 26° and ∠VUX will be 116°.

A circle is a geometrical figure which becomes by plotting a point around a fixed point by keeping a constant distance.

In our daily life, we always see circular objects for example our bike wheel.

The longest line which can be drawn inside the circle will be the diameter.

Area of circle = πr² and the perimeter of circle = 2πr where r is the radius of the circle.

Given the circle

Since ∠UOV is 128°

So,

∠UOW = 180 - ∠UOV

∠UOW = 180 - 128 = 52°

Now,

∠VUW = 1/2 ∠UOW

∠VUW = (1/2)52 = 26°

Now ∠VUX = ∠VUW + 90°

∠VUX = 26 + 90 = 116°

Hence "The value of the angle ∠VUW is 26° and ∠VUX will be 116°".

Answer:

x = 7.6

Step-by-step explanation:

Label the values you have on the triangle: The X is opposite, the 33 is your theta (ø) and 14 is your hypotenuse

Plug these values into the equation sin(ø)=o/h making the equation sin(33)=x/14.

Take the 14 and multiply it on the opposite side, making the equation look like this: 14xsin(33)=x

Then plug this into the TI-83/84 calculator and make sure it is degree mode (mode, degree)

Then just round to the nearest tenth. :)

Answer:

[tex]cos(\beta)=\frac{\sqrt{6}}{3}}[/tex]

Step-by-step explanation:

we know that

If the terminal ray of β lies in the fourth quadrant

then

sin (β) is negative and cos (β) is positive

Remember the trigonometric identity

[tex]sin^2(\beta)+cos^2(\beta)=1[/tex]

we have

[tex]sin(\beta)=-\frac{\sqrt{3}}{3}[/tex]

substitute

[tex](-\frac{\sqrt{3}}{3})^2+cos^2(\beta)=1[/tex]

[tex]\frac{3}{9}+cos^2(\beta)=1[/tex]

[tex]cos^2(\beta)=1-\frac{3}{9}[/tex]

[tex]cos^2(\beta)=\frac{6}{9}[/tex]

apply root square both sides

Answer:

(x + 2)(x - 7)

Step-by-step explanation:

Given

x² - 5x - 14

Consider the factors of the constant term (- 14) which sum to give the coefficient of the x- term (- 5)

The factors are + 2 and - 7, since

2 × - 7 = - 14 and 2 - 7 = - 5, thus

x² - 5x - 14 = (x + 2)(x - 7)

The standard deviation of sample data is "[tex]s = \sqrt{\frac{(x_1 -\bar{x})^2+ (x_2-\bar{x})^2 + ..... + (x_n -\bar{x})^2}{ n- 1}}[/tex]"

Random variables, samples, statistical populations, information sets, or probabilistic distributions are equal to the square root of its variance.

It's much less resilient in reality than the average absolute deviation, but it makes algebraic expressions easier.

A sampling divided by the size of the data set is less than one, n - 1. To get the standard deviation, take the square root of the variance. The standard deviation is obtained by taking the square root of the standard deviation.

Therefore, the standard deviation of sample data is "[tex]s = \sqrt{\frac{(x_1 -\bar{x})^2+ (x_2-\bar{x})^2 + ..... + (x_n -\bar{x})^2}{ n- 1}}[/tex]"

The length has to be greater than the absolute difference between the other two lengths, but less than the sum of them. In other words, if your unknown side length is a, and the other two are b and c, then its |b - c| < a < b + c

So, putting in your values, you have 10 - 7 < a < 10 + 7, which is 3 < a < 17

So, your range is from 3 to 17 (non inclusive).

The length has to be greater than the difference between the named two lengths, but less than the sum of them. So 3-17 is your answer.

Answer:

  -17

Step-by-step explanation:

Each term in the sequence is 5 less than the one before, so the first 4 terms are ...

  -2, -7, -12, -17

The 4th term of the sequence is -17.

__

The general term (an) of the sequence can be written as ...

  an = a1 +d(n -1)

where a1 is the first term and d is the common difference. Here, those are ...

  a1 = -2, d = -5

so the general term is ...

  an = -2 -5(n -1)

We can use this to find the 4th term:

  a4 = -2 -5(4 -3)

  a4 = -17

x = [-19 +/- sqrt(19² - 4(1)(c)]/2

x = [-19 +/- sqrt(361 - 4c)]/2

The difference of the roots would be:

sqrt(361 - 4c) = 15

361 - 4c = 15²

361 - 225 = 4c

Answer:

angle A = 166 degrees

Step-by-step explanation:

so first you have to look at the problem and see what type of relationship the angles have. so if you draw it out yourself, it makes it a little easier and you can see that the two angles are corresponding angles, which means theyre both congruent or, equal.

after you find that out you can set up an equation so,

7x + 40 = 3x + 112

you do the math...

4x + 40 = 112

4x = 72

x = 18

but you cant stop here, you have to plug in x to find teh entire angle A

7 (18) + 40 = ?

The image triangle compare to the pre-image triangle will be similar due to dilation.

Step-by-step explanation:

As given in the question ,the sequence of transformation undergone by a triangle are :-

Due to the process of  dilation, the two triangles will be similar. Another important factor is that the  scale factor is less than one and is a reduction, thus, the image  will be smaller than the pre-image but the triangle will be similar

The  transformations mentioned in the above statement altered the position and scale of the triangle, but the angle measures of both the triangle remains the same.

Thus we can say that

The image triangle compare to the pre-image triangle will be similar due to dilation.

Answer:

Sample Response: Because there was a dilation, the two triangles will be similar. The scale factor was less than one, so the image will be smaller than the pre-image.
