Answers

Answer 1

Answer:

The value of x and y are x = 15 and y = 63

Step-by-step explanation:

If two adjacent angle formed a straight line, then the two angles formed a pair of linear anglesThe sum of the measures of the linear angles is 180°

From the given figure

∵ The angles of measures (9x - 7)° and (4x - 8)° are adjacent angles

∵ The angles of measures (9x - 7)° and (4x - 8)° formed a line

∴ They formed a pair of linear angles

∵ The sum of the measures of the linear angles is 180°

→ That means add them and equate the sum by 180

(9x - 7) + (4x - 8) = 180

→ Add the like terms

∵ (9x + 4x) + (-7 + -8) = 180

∴ 13x + (-15) = 180

→ Remember (+)(-) = (-)

∴ 13x - 15 = 180

→ Add 15 to both sides

∴ 13x - 15 + 15 = 180 + 15

∴ 13x = 195

→ Divide both sides by 13

∵ [tex]\frac{13x}{13}[/tex] = [tex]\frac{195}{13}[/tex]

x = 15

∵ Lines m and n are parallels

∵ A line intersected them

∵ The angles of measures (2y + 2), (9x - 7) are interior alternate angles

The interior alternate angles are equal in measures

2y + 2 = 9x - 7

∵ x = 15

→ Substitute the value of x

∴ 2y + 2 = 9(15) - 7

∴ 2y + 2 = 135 - 7

∴ 2y + 2 = 128

→ Subtract 2 from both sides

∴ 2y + 2 - 2 = 128 - 2

∴ 2y = 126

→ Divide both sides by 2

∴ [tex]\frac{2y}{2}[/tex] = [tex]\frac{126}{2}[/tex]

y = 63

Answer 2

The values of x and y are 15 and 63, respectively

The angles in the figure are: (9x - 7)° and (4x - 8)°

These angles are adjacent angles.

So, we have:

[tex]\mathbf{9x - 7 + 4x - 8 = 180}[/tex]

Collect like terms

[tex]\mathbf{9x + 4x = 180 + 8 + 7}[/tex]

[tex]\mathbf{13x = 195}[/tex]

Divide both sides by 13

[tex]\mathbf{x = \frac{195}{13}}[/tex]

[tex]\mathbf{x = 15}[/tex]

Also, we have:

[tex]\mathbf{2y + 2 = 9x - 7}[/tex] -- interior angles

Subtract 2 from both sides

[tex]\mathbf{2y = 9x - 9}[/tex]

Substitute 15 for x

[tex]\mathbf{2y = 9\times 15 - 9}[/tex]

[tex]\mathbf{2y = 126}[/tex]

Divide both sides by 2

[tex]\mathbf{y = 63}[/tex]

Hence, the values of x and y are 15 and 63, respectively

In the figure shown, What is the value of x? a. 57° b. 123° c. 33° d. 147°

Answers

Answer:
d. 147 degrees

Explanation:
Please check the picture attached after reading the explanation :)

Assuming that l1 and l2 are parallel, we can identify that the angle at the intersection point of l3 and l2 is the alternate exterior angle of the angle that measures 57 degrees.

This means that that angle also measures 57 degrees.

We can see that l2, l4 and l3 form this little triangle at the corner and we now know that one of its angles measure 90 degrees and the other measures 57 degrees.

In a triangle, the sum of all its interior angles is equal to 180 degrees so we can find the last angle of the triangle by subtracting 90 and 57 from 180.

180-57-90
=33 degrees

A straight lines has an angle measure of 180 degrees as well, so we can find angle x by subtracting 33 from 180.

180-33
=147

Therefore, the measure of angle x is 147 degrees.

Tthe area of a circle increases at a rate of 5 cm^2/s.

Required:
a. How fast is the radius changing when the radius is 4 cm?
b. How fast is the radius changing when the circumference is 5 cm?

Answers

Answer:

(a) 0.198 cm/s (b) 1 cm/s

Step-by-step explanation:

It is given that,

The rate of change of area of a cicle, [tex]\dfrac{dA}{dt}=5\ cm^2/s[/tex]

(a) The area of a circle is given by :

[tex]A=\pi r^2[/tex]

Differentiate both sides,

[tex]\dfrac{dA}{dt}=2\pi r\dfrac{dr}{dt}\\\\\text{Put the value of dA/dt and r = 4 cm}\\\\\dfrac{dr}{dt}=\dfrac{dA/dt}{2\pi r}\\\\\dfrac{dr}{dt}=\dfrac{5}{2\pi \times 4}\\\\\dfrac{dr}{dt}=0.198\ cm/s[/tex]

(b) Circumference, [tex]C=2\pi r[/tex] = 5 cm

[tex]\dfrac{dA}{dt}=2\pi r\dfrac{dr}{dt}\\\\\dfrac{dr}{dt}=\dfrac{dA/dt}{2\pi r}\\\\\dfrac{dr}{dt}=\dfrac{5}{5}\\\\\dfrac{dr}{dt}=1\ cm/s[/tex]

Hence,

(a) 0.198 cm/s (b) 1 cm/s

200, 300, 400, 600, 1000
a) min-max normalization by setting min = 0 and max = 1
b) z-score normalization
c) normalization by decimal scaling

Answers

Step-by-step explanation:

b is the answer , z-score normalization

Normalization is applied to data values in other to ensure that the data scales well, such that data values conforms to a certain range. The output of the various normalization techniques are given below ;

Given the data:

200, 300, 400, 600, 1000

1.)

Min - Max normalization :

[tex]\frac{value - min}{max - min} [/tex]

Min = minimum = 200

Max = maximum = 1000

Value = 200 :

[tex]\frac{200 - 200}{1000 - 200} = 0[/tex]

Value = 300 :

[tex]\frac{300 - 200}{1000 - 200} = 0.125[/tex]

Value = 400 :

[tex]\frac{400 - 200}{1000 - 200} = 0.25[/tex]

Value = 600 :

[tex]\frac{600 - 200}{1000 - 200} = 0.5[/tex]

Value = 1000 :

[tex]\frac{1000 - 200}{1000 - 200} = 1[/tex]

Normalized values = (0, 0.125, 0.25, 0.5, 1)

2.)

Zscore normalization :

[tex]\frac{value - μ}{σ} [/tex]

Using a calculator :

Mean, μ = 500Standard deviation = 316.227

Value = 200 :

[tex]\frac{200 - 500}{316.227} = -0.949[/tex]

Value = 300 :

[tex]\frac{300 - 500}{316.227} = -0.632[/tex]

Value = 400 :

[tex]\frac{400 - 500}{316.227} = -0.316[/tex]

Value = 600 :

[tex]\frac{600 - 500}{316.227} = 0.316[/tex]

Value = 1000 :

[tex]\frac{1000 - 500}{316.227} = 1.581[/tex]

Normalized values = (-0.949, -0.632, -0.316, 0.316, 1.581)

3.)

Decimal Scaling :

Maximum value = 1000

Hence, we can divide our values by 10000

200 / 10000 = 0.02

300/1000 = 0.03

400/1000 = 0.04

600/1000 = 0.06

1000/1000 = 0.1

Hence, the Normalized values (0.02, 0.03, 0.04, 0.06, 0.1)

Answer:

41 1/6 is the answer lets do it step by step

Determine whether the Mean Value Theorem can be applied to f on the closed interval [a, b]. If the Mean Value Theorem can be applied, find all values of c in the open interval (a, b) such that f '(c) = f (b) − f (a) b − a . If the Mean Value Theorem cannot be applied, explain why not.

f(x) = x^3 + 2x, [-1,1]

Answers

Answer:

There is a value of [tex]c[/tex] in (-1, 1), [tex]c = 0.577[/tex].

Step-by-step explanation:

Let [tex]f(x) = x^{3}+2\cdot x[/tex] for [tex]x \in[-1,1][/tex], we need to prove that [tex]f(x)[/tex] is continuous and differentiable to apply the Mean Value Theorem. Given that [tex]f(x)[/tex] is a polynomical function, its domain comprises all real numbers and therefore, function is continuous.

If [tex]f(x)[/tex] is differentiable, then [tex]f'(x)[/tex] exists for all value of [tex]x[/tex]. By definition of derivative, we obtain the following expression:

[tex]f'(x) = \lim_{h \to 0} \frac{f(x+h)-f(x)}{h}[/tex]

[tex]f'(x) = \lim_{h \to 0} \frac{(x+h)^{3}+2\cdot (x+h)-x^{3}-2\cdot x}{h}[/tex]

[tex]f'(x) = \lim_{h \to 0} \frac{x^{3}+3\cdot x^{2}\cdot h+3\cdot x\cdot h^{2}+h^{3}+2\cdot x+2\cdot h-x^{3}-2\cdot x}{h}[/tex]

[tex]f'(x) = \lim_{h \to 0} \frac{3\cdot x^{2}\cdot h+3\cdot x\cdot h^{2}+h^{3}+2\cdot h}{h}[/tex]

[tex]f'(x) = \lim_{h \to 0} 3\cdot x^{2}+ \lim_{h \to 0} 3\cdot x \cdot h+ \lim_{h \to 0} h^{2}+ \lim_{h \to 0} 2[/tex]

[tex]f'(x) = 3\cdot x^{2}+2[/tex] (Eq. 2)

The derivative of a cubic function is quadratic function, which is also a polynomic function. Hence, the function is differentiable at the given interval.

According to the Mean Value Theorem, the following relationship is fulfilled:

[tex]f'(c) = \frac{f(1)-f(-1)}{1-(-1)}[/tex] (Eq. 3)

If we know that [tex]f(-1) = -3[/tex], [tex]f(1) = 3[/tex] and [tex]f'(c) = 3\cdot c^{2}+2[/tex], then we expand the definition as follows:

[tex]3\cdot c^{2}+2 = 3[/tex]

[tex]3\cdot c^{2} = 1[/tex]

[tex]c = \sqrt{\frac{1}{3} }[/tex]

[tex]c \approx 0.577[/tex]

There is a value of [tex]c[/tex] in the interval (-1, 1), [tex]c = 0.577[/tex].
