Answer: 16.8

Step-by-step explanation:

2:25 = X:210

210/25 = 8.4

Multiply 8.4 by 2

The figure is an illustration of the relationship between the angles in a circle and arc

From the figure, the arc PQ is subtended by the angle PAQ.

This means that:

PQ = ∠PAQ

Given that ∠PAQ = 130, it means that:

Arc PQ = 130

The measure of PSQ is then calculated using:

∠PSQ = 0.5 * Arc PQ ----- inscribed angle is half a subtended angle.

This gives

∠PSQ = 0.5 * 130

∠PSQ = 65

Hence, the measure of ∠PSQ is 65 degrees

A semicircle measures 180 degrees.

This means that:

QR + PQ = 180

So, we have:

QR = 180 - PQ

Substitute 130 for PQ

QR = 180 - 130

QR = 50

Hence, the measure of QR is 50 degrees

The measure of arc RS is then calculated using:

∠RPS = 0.5 * Arc RS ----- inscribed angle is half a subtended angle.

Where ∠RPS = 35

So, we have:

35 = 0.5 * Arc RS

Multiply both sides by 2

Arc RS = 70

Hence, the measure of RS is 70 degrees

In (a), we have:

∠PSQ = 65

This means that:

∠PSQ = ∠PSB = 65

So, we have:

∠PSB = 65

Next, calculate SBP using:

∠SBP + ∠BPS + ∠PSB = 180 ---- sum of angles in a triangle.

So, we have:

∠SBP + 35 + 65 = 180

∠SBP + 100 = 180

This gives

∠SBP = 80

The measure of AQS is then calculated using:

AQS = AQB = 180 - (180 - SBP) - (180 - PAQ)

This gives

AQS = 180 - (180 - 80) - (180 - 130)

Evaluate

AQS = 30

Hence, the measure of AQS is 30 degrees

A semicircle measures 180 degrees.

This means that:

PS + RS = 180

This gives

PS = 180 - RS

Where RS = 70

So, we have:

PS = 180 - 70

Evaluate

PS = 110

Hence, the measure of arc PS is 110 degrees

          What is the equation of the line in slope intercept form if its slope is 8 and its y-intercept is -3?

[tex]\blue{\textsf{\textbf{\underline{\underline{Answer:-}}}}[/tex]

y=8x-3

[tex]\blue{\textsf{\textbf{\underline{\underline{How to solve:-}}}}[/tex]

Slope Intercept form, as the name implies, has slope & intercept in its equation.

It looks like y=mx+b, where "m" is the slope and "b" is the y-intercept.

To determine the equation of the line, we need to write the value of m, which in this case is 8, in lieu of m:-

y=8x+b

Same with the y-intercept:-

[tex]\tt{y=8x+(-3)}[/tex]

Which simplifies to

What is the Value of Cot 75 Degrees in Terms of Tan 75°? Since the cotangent function is the reciprocal of the tangent function, we can write cot 75° as 1/tan(75°). The value of tan 75° is equal to 2 + √3.

Answer:

Bisect means to divide it into two, so you can draw a line such that both resulting sides are 45 degrees.

If the plane of the loop is perpendicular to the magnetic field then the θ will be zero. Then the torque will also be zero.

The torque that may cause an item to revolve along an axis is measured as torque. The axis of rotation is the point at which the item rotates.

A rectangular coil of wire, 22.0cm by 35.0cm and carrying a current of 1.95 Ampere, is oriented with the plane of its loop perpendicular to a uniform 1.50 Tesla magnetic field.

Then the torque that the magnetic field exerts on the coil will be

The torque is given as

[tex]\rm \tau = I \overrightarrow{A} \times \overrightarrow{B}[/tex]

The strength of magnetic torque on the current-carrying circle is given by θ: if θ is the angle between A and B. Then we have

[tex]\rm \tau = I AB \sin \theta[/tex]

When the loop plane is perpendicular to the magnetic field, the amplitude of magnetic torque on the current-carrying circle is zero.

Then θ = 0

Then we have

[tex]\rm \tau = I AB \sin 0\\\\\tau = 0[/tex]

The solution to the system of linear equation x + y = 4 and x - y = 6 is (5, -1).

x + y = 4

x - y = 6

Therefore, let's add the equations.

2x = 10

divide both sides by 2

x = 10 / 2

x = 5

Let's find the value of y

Therefore,

x + y = 4

5 + y = 4

y = 4 - 5

y = - 1

Therefore, the solution of the system of equation is (5, -1)

By using the Pythagorean identity the value of tan [tex]\theta[/tex] will be ∞.

tan [tex]\theta[/tex] = ∞.

Pythagorean identities are identities in trigonometry that are extensions of the Pythagorean theorem. The fundamental identity states that for any angle [tex]\theta[/tex],

[tex]sin \; ^{2} \theta + cos \; ^{2} \theta =1[/tex]

By Pythagorean Identity we have,

we have, [tex]sin \theta \; = \; -1[/tex]

So, [tex](-1)^{2} \; + \; cos^{2}\; \theta =\; 1[/tex]

[tex]\; cos^{2}\; \theta =\; 1 - \; 1[/tex]

[tex]cos^{2}\; \theta =0[/tex]

[tex]cos\; \theta =0[/tex]

Now, we know that

[tex]tan \; \theta= \frac{sin\; \theta}{cos\; \theta}[/tex]

        =  [tex]\frac{-1}{0}[/tex]

  [tex]tan \; \theta=[/tex] ∞....................... (1)

The corresponding z score for a grade of 81.8% for a class with average grade of 83% and standard deviation of 4.2% is -0.29.

The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

z = (raw score - mean) / standard deviation

Given that mean is 83%, standard deviation = 4.2%, for x = 81.8:

z = (81.8 - 83)/4.2 = -0.29

The length of the base of the triangle is, 9.1 inches

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

The area of the triangle below is 23.66 square inches.

And, The height = 5.2 inches

We know that;

Area of triangle = 1/2 × Base × Height

Substitute all the values we get;

Answer:

1,017.36

Step-by-step explanation:

To find the volume of a cylinder, you need to figure out the radius and height.

We've already been given the height, which is 9 meters.

Now let's find the radius.

To find the radius you have to divide the diameter by 2, which means 12/2, which is 6.

Now let's plug it into the formula:  [tex]V = \pi r^{2} h[/tex]

So, 3.14 x [tex]6^{2}[/tex] x 9.

Solve the exponent, giving us 36.

3.14 x 36 x 9 = the volume.

The graph of y = √x is reflected in the y-axis, is horizontally stretched by a factor of 2, shifted 3 units up and 1 unit left. What is the equation of the transformed graph?

Original: y = √(x)

Reflected in the y-axis: y = √(-x)

Horizontally stretched by a factor of 2: y = √(-x/2)

Shifted 3 units up: y = 3 + √(-x/2)

And 1 unit left: y = 3 + √(-(x+1)/2)

The equation of the transformed function is y = (-5x)³.

A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of modifying a shape's size or position.

we have, Function

y = x³

Scale factor = 1/5

Now, stretch the function horizontally by factor 1/5 then

y = (5x)³
