Find the value of x.
2x + 30
3x - 5
X - 15
X=

Answers

Answer:

x = 50

Step-by-step explanation:

Angle 2x + 30 is exterior which is equal to sum of non-adjacent interior angles:

3x + 30 = 3x - 5 + x - 153x + 30 = 4x - 204x - 3x = 30 + 20x = 50

given r,s, and p, which angle is not congruent to 4?

Answers

Answer:

Line R, S, and P are parallel lines meaning any lines that pass through them will form the same angles. Look at 4 and 2. One line is intersecting S and P to for the same angles. Corresponding angles in parallel lines which are formed by an intersecting line are equal. Therefore 4 and 2 are equal. That leaves B, C, and D left. 4 is also congruent to 5.  This is because if 4 is congruent to 2 and 2 is congruent to 5 by vertical angles theorem, 5 must be equal to 4 (transitive property of equality: is a=b and b=c then a=c)

That leaves B and D left. Notice the angle made at the very top left. Across from that unlabeled angle is 6. By vertical angles theorem those 2 angles are congruent. The unmarked angle is equal to 2 and 4 because corresponding angles in parallels are congruent. Therefore lets mark that unmarked angle as 0. If the m< 6 = m< 0 and the m<0= the m<4 then m<6 must equal the m<4.

That leaves Just B remaining thus B is NOT congruent to 4

I need help answering this question

Answers

Answer:

[tex] x = 7 [/tex]

Step-by-step explanation:

Given that AB and BC are perpendicular, it follows that:

m<ABC = right angle = 90°

Thus:

[tex] 75 + (x + 8) = 90 [/tex] (angle addition postulate)

Solve for x

[tex] 75 + x + 8 = 90 [/tex]

[tex] 83 + x = 90 [/tex]

Subtract 83 from each side

[tex] 83 + x - 83 = 90 - 83 [/tex]

[tex] x = 7 [/tex]

Here is a sequence: 500, 100, 20, . . . Explain why this sequence could be a geometric sequence.

Answers

A geometric sequence is a sequence in which the numbers are multiplied by a fixed number called the common ratio. For example the sequence 2,6,18,54 all have the common ratio of 3! 2*3=6, and 6*3=18, and 18*3=54!!!!!!!
The answer to this problem would be a geometric sequence! Here’s why:, each term has the common ratio of 1/5!!!!!!! 500*1/5=100....and so on
There fore your answer is this sequence could be geometric because it can be multiplied by a fraction in order to get the next term!!!!!!! Hope this helped

A sequence is said to be Geometric sequence if there is a common ratio 'r' in each successive term and the previous term.

[tex]r=\frac{\text{Successive term}}{\text{Previous term}}[/tex]

Given sequence is,

500, 100, 20......

Ratio of 2nd and 1st term = [tex]\frac{100}{500}[/tex]

                                          = [tex]\frac{1}{5}[/tex]

Ratio of 3rd and 2nd term = [tex]\frac{20}{100}[/tex]

                                           = [tex]\frac{1}{5}[/tex]

Therefore, there is a common ratio 'r' = [tex]\frac{1}{5}[/tex]

And the given sequence will be geometric sequence.

Answer:

mera bahi mil nhi rha h abhay ko jante h

Answer:

sin([tex]\frac{7\pi }{4}[/tex] ) = -[tex]\frac{\sqrt{2} }{2}[/tex]

Step-by-step explanation:

If cos(theta) = [tex]\frac{\sqrt{2} }{2}[/tex], then theta should equal [tex]\frac{\pi }{4}[/tex] or [tex]\frac{7\pi }{4}[/tex]  since both angles are on the right side of the origin, meaning the cosine would be positive. However, it states that the angle theta terminates at quadrant IV so the only angle that would meet this criteria is [tex]\frac{7\pi }{4}[/tex] .

So theta should equal [tex]\frac{7\pi }{4}[/tex] .

Now that we have theta, all you have to do is find the value of sine by plugging it in.

sin([tex]\frac{7\pi }{4}[/tex] ) = -[tex]\frac{\sqrt{2} }{2}[/tex]

x = 10 - y and y = x - 8

Answers

Answer:

x = 9 and y = 1

Step-by-step explanation:

Here,

x = 10 - y and y = x - 8 is given

then, name the equation

x = 10 - y ...(1)

y = x - 8 ...(2)

Now, put the value of x in equation (2) we get

y = x - 8

y = (10 - y) - 8

y = 10 - y - 8

y + y = 10 - 8

2y = 2

y = 2÷2

y = 1

Here, we get the value of y = 1

Now, we put the value of y in equation (1) we get

x = 10 - y

x = 10 - (1)

x = 10 - 1

x = 9

VERIFICATION:

x = 10 - y

9 = 10 - 1

9 = 9

Hence, LHS = RHS

D. 200

Answers

Answer:

B. 268

Step-by-step explanation:

The new mean for the given data set can be obtained as 268.

How to calculate the average or mean?

In order to calculate average, divide the total sum of the data to the total number of data. An average is a standard number for a given data whose value can both be more or less than it.

The given data is 225, 259, 306, 325, 350.

And, its mean is given as 293.

Here, the number of elements is 5.

If 25 is subtracted from each value, new mean can be evaluated as below,

New mean = (Old mean × 5 - 25 × 5)/5

⇒ (293 × 5 - 25 × 5)/5

⇒ 293 - 25 = 268

Hence, the new mean can be obtained as 268.

Find the average rate of change of g(x)= -4x^3+1 from x= -4 to x = 1

Answers

Answer:

[tex]Rate = -52[/tex]

Step-by-step explanation:

Given

[tex]g(x) = -4x^3 + 1[/tex]

x = -4 to x = 1

Required

Determine the average rate of change

This is calculated using:

[tex]Rate = \frac{g(b) - g(a)}{b - a}[/tex]

Where

[tex]a = x = -4[/tex]

[tex]b = x = 1[/tex]

Calculating g(b):

g(b) = g(1)

If [tex]g(x) = -4x^3 + 1[/tex], then

[tex]g(1) = -4(1)^3 + 1[/tex]

[tex]g(1) = -4*1 + 1[/tex]

[tex]g(1) = -4 + 1[/tex]

[tex]g(1) = -3[/tex]

Calculating g(a):

g(a) = g(-4)

If [tex]g(x) = -4x^3 + 1[/tex], then

[tex]g(-4) = -4(-4)^3 + 1[/tex]

[tex]g(-4) = -4*-64 + 1[/tex]

[tex]g(-4) = 256 + 1[/tex]

[tex]g(-4) = 257[/tex]

So, the formula:

[tex]Rate = \frac{g(b) - g(a)}{b - a}[/tex]

becomes

[tex]Rate = \frac{g(1) - g(-4)}{1 - (-4)}[/tex]

[tex]Rate = \frac{g(1) - g(-4)}{1+4}[/tex]

[tex]Rate = \frac{g(1) - g(-4)}{5}[/tex]

[tex]Rate = \frac{-3 - 257}{5}[/tex]

[tex]Rate = \frac{-260}{5}[/tex]

[tex]Rate = -52[/tex]

A circle has a diameter of 10 meters. What is the length of the arc subtended by a central angle of 4 radians.

A. 40 meters
B. 20 meters
C. 4 meters
D. 10 meters

Answers

Answer:

b

Step-by-step explanation:

The length of the arc subtended by a central angle of 4 radians = 20 m

Diameter of the circle = 10 m

Radius of the circle = 5 m

Central angle in radians = 4 radians

The length of arc for the circle can be determined by the formula as formulated in equation (1)

[tex]\rm L = Length\; of \; Arc \\\theta = Central \; Angle \; in \; radians \\r = Radius\; of\; the\; circle\\L = \theta \times r.......(1)[/tex]

From equation (1) we can write that

[tex]\rm L = 5 \times 4 = 20 \; m[/tex]

The length of the arc subtended by a central angle of 4 radians = 20 m

Mrs. Culland is finding the center of a circle whose equation
is x2 + y2 + 6x - 4y – 3 = 0 by completing the square. Her
work is shown.
x2 + y2 + 6x + 4y - 3 = 0
x2 + 6x + y2 + 4y - 3 = 0
(x2 + 6x) + (12 + 4y) = 3
(x2 + 6x + 9) + (y2 + 4y + 4) = 3 + 9 + 4
Which completes the work correctly?
(x - 3)2 + ( - 2)= 42, so the center is (3,2).
(x + 3)2 + (y + 2)2 = 42, so the center is (3, 2).
(x - 3)2 + (x - 2)2 = 42, so the center is (-3,-2).
(x + 3)2 + (y + 2)2 = 42, so the center is (-3, -2).

Answers

Answer:

centre of circle (h,k) is (-3,-2)

Option D is Correct.

Step-by-step explanation:

The centre of circle can be found from the equation as:

[tex](x-h)^2+(y-k)^2=r^2 \ then \ (h,k) \ is \ center[/tex]

So, the steps then by Mrs Culland are:

[tex]x^2 + y^2 + 6x + 4y - 3 = 0\\x^2 + 6x + y^2 + 4y - 3 = 0\\(x^2 + 6x) + (y^2 + 4y) = 3\\(x^2 + 6x + 9) + (y^2 + 4y + 4) = 3 + 9 + 4[/tex]

The next step will be:

[tex](x + 3)^2 + (y + 2)^2 = 16[/tex]

I assume there is some calculating mistake in the given options. Instead of 42 there should be 16, according to solution shown above.

The general equation of circle is

[tex](x-h)^2+(y-k)^2=r^2 \ then \ (h,k) \ is \ center[/tex]

In our case: [tex](x + 3)^2 + (y + 2)^2 = 16[/tex]

h= -3 and k= -2, so the centre of circle (h,k) is (-3,-2)

Option D is Correct.

Answer:

D,,,, (x+3)²+(y+2)²=4², so the center is (-3, -2).
