Answer:

C

Step-by-step explanation:

8x^2 -  8x + 2

=2(4x^2 - 4x  + 1)

=2(2x - 1)^2

Vertex of the angle is 11.31 cm far from the center of the circle.

     Given in the question,

In ΔOPV and ΔOQV,

OP ≅ OQ (Radii of the circle)

PV ≅ QV (Tangents from a point outside the circle)

OV ≅ OV (Reflexive property)

ΔOPV ≅ ΔOQV (SSS property of congruence)

Therefore, m∠PVO = m∠QVO = 45°

By triangle sum theorem,

m∠POV + m∠PVO + m∠OPV = 180°

m∠POV + 45° + 90° = 180°

m∠POV = 45°

Hence, ΔOPV is an isosceles triangle.

OP = PV = 8 cm

By applying Pythagoras theorem in ΔOPV.

OV² = OP² + PV²

OV² = 8² + 8²

OV = √128

OV = 11.31 cm

   Therefore, vertex V is 11.31 cm from the center of the circle.

The distance from the vertex of the angle to the center of the circle is 0 centimeters.

In this problem, we have two tangents to a circle, and we are given that the angle between them is 90 degrees. We need to find the distance from the vertex of the angle to the center of the circle.

Since the angle between the tangents is 90 degrees, the tangents are perpendicular to each other. This means that the vertex of the angle is located on the circumference of the circle, and it forms a right triangle with the center of the circle and one of the points where the tangents intersect the circle.

Using the Pythagorean theorem, we can find the distance from the vertex to the center of the circle. Let's call this distance x. We know that the radius of the circle is 8 centimeters, so one leg of the right triangle is 8 centimeters. The other leg is x centimeters, and the hypotenuse is the radius of the circle plus x centimeters.

Applying the Pythagorean theorem, we have:

x^2 + 8^2 = (8 + x)^2

Simplifying the equation, we get:

x^2 + 64 = 64 + 16x + x^2

Cancelling out x^2 terms, we have:

64 = 64 + 16x

Subtracting 64 from both sides, we get:

0 = 16x

Dividing both sides by 16, we get:

x = 0

Since we cannot have a distance of 0, the equation does not have a solution. This means that the vertex of the angle is located at the center of the circle, and the distance is 0 centimeters.

Answer:

A

Step-by-step explanation:

This can be easily seen. 7/14 simplified is 1/2. When 20/40 is simplified, it's also 1/2

To solve the inequality -3(-3x - 4) < 66, first distribute the -3, then isolate the variable term resulting in 9x < 54 and divide by 9 to find x < 6 as the solution set.

Solving the Inequality

To solve the inequality -3(-3x - 4) < 66, we first distribute the -3 across the terms within the parentheses, which gives us 9x + 12 < 66.

Next, we subtract 12 from both sides to isolate the term with the variable, resulting in 9x < 54. Finally, we divide both sides by 9 to solve for x, which yields x < 6.

Thus, the solution set to the inequality is all real numbers less than 6.

Answer:

[tex]13.65^0.[/tex]

Step-by-step explanation:

Given,

Height of tee, H = 43 yard

Direct distance of the hole is, D = 177 yards

Now, Angle of depression of tee

[tex]\tan \theta = \dfrac{H}{D}[/tex]

[tex]\tan \theta = \dfrac{43}{177}[/tex]

[tex]\tan \theta =0.2429[/tex]

[tex]\theta = 13.65^\circ[/tex]

Hence, angle of depression from tee to the green is [tex]13.65^0.[/tex]

Answer:[tex]330^{\circ}[/tex]

Step-by-step explanation:

Given

Circumference of circle [tex]C=12\ units[/tex]

Arc length [tex]l=11\ units[/tex]

we know arc length is given by

[tex]l=\frac{\theta }{360^{\circ}}\times 2\pi r[/tex]

substituting value we get

[tex]11=\frac{\theta }{360}\times 12[/tex]

[tex]\frac{11}{12}=\frac{\theta }{360}[/tex]

[tex]\therefore \ \theta =330^{\circ}[/tex]

The central angle of the arc is approximately 330 degrees.

The question involves finding the central angle of an arc in degrees when the circumference of the circle is 12 and the arc length is 11. To solve this, it's essential to understand the relationship between the arc length, the central angle, and the circumference of the circle.

The formula we use is (Central Angle in degrees) / 360 = Arc Length / Circumference. Given that the circumference is 12 and the arc length is 11, we can substitute these values into the formula to find the central angle.

Thus, the calculation is as follows: (Central Angle in degrees) / 360 = 11 / 12.

By cross-multiplication, we find that the

Central Angle in degrees = (11 / 12) × 360.

This gives us a central angle of approximately 330 degrees.

Answer:250 N

Step-by-step explanation:

Given

mass of skater on left side [tex]m_l=70\ kg[/tex]

mass of skater on right side [tex]m_r=90\ kg[/tex]

If the skater on the left experience a force of [tex]250\ N[/tex]

If they push against each other then they must experience  an equal force according to newtons third law

Thus [tex]F_l=F_r[/tex]

Thus skater on right experience [tex]250\ N[/tex] force

Using Newton's third law, if the first skater pushes off with a force of 250 N, the second skater will experience an equal but opposite force of 250 N. This occurs irrespective of the skaters' masses.

The subject of this question is physics, specifically Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. In this case, the action is the first skater pushing off the second skater, and the reaction is the force experienced by the second skater.

The amount of force experienced by the first skater is 250 N. Because of Newton's third law, this means the second skater is also experiencing a force of 250 N. The direction of the force, however, is in the opposite direction to the force experienced by the first skater.

The force experienced by an object is independent of its mass. Therefore, despite the second skater having a mass of 90.0 kg versus the first skater's 70.0 kg, the force experienced remains the same.

In conclusion, the second skater experiences a force of 250 N.

B) 53%

C) 37%

D) 63%

E) Yes.

Step-by-step explanation:

A) 53 people did not get headaches at all.

B) To solve for the percentage of participants that reported they did not get a migraine headache, you will need to divide out of the TOTAL number of people:

53/100= .53 --> Convert to percentage--> .53×100 = 53%.

C) To find this value, you will need to divide out of the amount of people that took MEDICINE and got a headache:

22/60≈0.367--> Convert to percentage --> 0.367×100≈37%

D) This percentage will be found out of who did NOT take the medicine:

25/40= 0.625 --> Convert to percentage --> 0.625×100≈63%

E) The medicine did help prevent migraine headaches because the percentage that got migraines with the medicine is lower than the percentage that got migraines WITHOUT the medicine.

Answer:

Expression A and C are correct because 9x - 3x = 6x and 5x + x = 6x, then -4

After simplification, Expression A (6x - 4) and Expression C (6x - 4) are equivalent to each other, but Expression B (12x - 4) is not equivalent to the other two.

The student's teacher presented a problem to determine the equivalence of three algebraic expressions: Expression A (9x - 3x - 4), Expression B (12x - 4), and Expression C (5x + x - 4).

Brianna incorrectly states that all three expressions are equivalent simply because they all evaluate to -4 when x = 0. However, this is a misinterpretation, as equivalence between algebraic expressions means that they yield the same result for all values of x, not just a single value.

To correct this, we simplify each expression:

Expression A: 9x - 3x - 4 simplifies to 6x - 4.

Expression B: 12x - 4 remains the same.

Expression C: 5x + x - 4 simplifies to 6x - 4.

After simplification, we see that Expression A is equivalent to Expression C, both simplifying to 6x - 4. However, Expression B remains different, with the term 12x - 4.a

Answer:

Step-by-step explanation:

x² - 17x + 72 = 0

Sum = -17

Product  = 72

Factor = 8 , 9

x² - 17x + 72 = 0

x² - 8x -9x + (-8)*(-9) = 0

x(x - 8) -9(x -8) = 0

(x - 8 ) (x - 9) = 0

Length = (x - 8) units

Width = (x - 9) units

The dimensions of the rectangle are 9 inches (width) and 16 inches (length) as obtained from solving the quadratic equation derived from the facts provided.

To solve this problem, let's denote the width of the rectangle as x in inches. Since we know that the length of the rectangle is 7 inches longer than its width, we can write it as x + 7 inches. The area of a rectangle is calculated by multiplying its length by its width. Here, it's given as 144 square inches.

Setting up the equation for the area, we get x(x + 7) = 144.

Solving this quadratic equation, we find that x = 9. As a result, the width is 9 inches and the length, being 7 inches longer, is 16 inches. Therefore, the dimensions of the rectangle are 9 inches by 16 inches.
