Answer:

The correct answer option is B. 0.21.

Step-by-step explanation:

We are to find the value of [tex]cos \theta[/tex] using the law of cosines.

We know that the formula of the cosine rule is given by:

[tex] c ^ 2 = a ^ 2 + b ^ 2 - 2 a b cos C [/tex]

So substituting the given values in the above formula:

[tex] 10.9 ^ 2 = 5.8 ^ 2 + 10.5 ^ 2 - 2 (5.8) (10.5) cos C [/tex]

[tex]118.81=33.64+110.25-121.8cosC[/tex]

[tex]118.81 - (33.64+110.25) = -121.8cosC[/tex]

[tex]118.81-143.86=-121.8cosC[/tex]

[tex]cosC=\frac{-25.05}{-121.8}[/tex]

cos C = 0.21

Answer:

(x−4)² + (y−5)² = 36

Step-by-step explanation:

The equation of a circle is:

(x−h)² + (y−k)² = r²

where (h, k) is the center and r is the radius.

If the center is (4, 5) and the radius is 6, then the equation is:

(x−4)² + (y−5)² = 6²

(x−4)² + (y−5)² = 36

Answer:

Part 1) The value of w is 13.3 units

Part 2) The value of x is 10.3 units

The answer is the option

w=13.3, x=10.3

Step-by-step explanation:

see the attached figure with letters to better understand the problem

Part 1) Find the value of w

we know that

In the right triangle ABD

tan(42°)=12/w

Solve for w

w=12/tan(42°)=13.3 units

Part 2) Find the value of x

In the right triangle ABC

tan(27°)=12/(w+x)

(w+x)=12/tan(27°)=23.6 units

(w+x)=23.6 units

Solve for x

x=23.6-w

substitute the value of w

x=23.6-13.3=10.3 units

The measure of side lengths w and w are 13.3 and 10.3 units respectively.

The correct option is A) w = 13.3; x = 10.3

The figures in the image are those of two right triangles.

To solve for the measure of side length w and x, we use the trigonometric ratio:

First, we solve for side length w:

Angle θ = 42 degrees

Opposite to angle θ = 12

Adjacent to angle θ = w

tan(θ) = opposite / adjacent

tan( 42 ) = 12 / w

w = 12 / tan( 42 )

w = 13.3

Now we solve for side length x:

Angle θ = 27 degrees

Opposite to angle θ = 12

Adjacent to angle θ = ( w + x )

tan(θ) = opposite / adjacent

tan( 27 ) = 12 / ( w + x )

( w + x ) = 12 / tan( 27 )

( w + x ) = 23.55

Plug in w = 13.3

13.3 + x = 23.55

x = 23.55 - 13.3

x = 10.3

Therefore, the value of x is 10.3 units

Option A) w = 13.3 and x = 10.3 is the correct answer.

Answer: the height would be 15

Step-by-step explanation:

v= pi*radius^2*height

1215pi mm= pi*9^2*height

1215pi mm= pi*81*height

(divide by pi on both sides, which isolates pi on both sides)

1215 mm= 81*height

(divide by 81 on both sides, which would isolate 81 on the right side of the equation)

1215/81= 15= height

The height of the cylinder is 15 mm.

To find the height of a cylinder, we can use the formula for the volume of a cylinder, which is V = πr²h, where V is the volume, r is the radius, and h is the height.

Given that the volume is 1215π mm and the radius is 9 mm, we can plug these values into the formula and solve for h.

1215π = π(9)²h

Simplifying the equation, we have:

1215 = 81h

Dividing both sides by 81, we find:

h = 15 mm

Therefore, the height of the cylinder is 15 mm.

Answer:

c

Step-by-step explanation:

Given the roots are x = - 1 + 4i and x = - 1 - 4i then the factors are

(x - (- 1 + 4i))(x - (- 1 - 4i))

= (x + 1- 4i )(x + 1 + 4i )

= (x + 1)² - 16i² → [ i² = - 1 ]

Expand and simplify

Hence

x² + 2x + 17 = 0 → c

Answer:

c(x) = –8x^2 + 3x – 5 is a quadratic

Step-by-step explanation:

A quadratic function involves the 2nd power of x:  x^2, and may (or may not) involve the 1st and zeroth power of x.

a(x) = -2x^3 is not a quadratic because of that exponent 3; in a quadratic, the highest power is always 2.

b(x) = 5x^3 + 8x^2 + 3 is not a quadratic for the same reason that a(x) is not a quadratic.

c(x) = –8x^2 + 3x – 5 is a quadratic:  the highest power of x is x^2, the other powers are x^1 and x^0.

Jordan will save $16.25 each month by choosing financing through the dealership.

Step-by-step explanation:

The EMI formula is :

[tex]\frac{p\times r\times(1+r)^{n}}{(1+r)^{n}-1}[/tex]

Case 1:

p = 17500

r = [tex]6.9/12/100=0.00575[/tex]

n = [tex]5\times12=60[/tex]

Putting the values in formula;

[tex]\frac{17500\times0.00575\times(1+0.00575)^{60}}{(1+0.00575)^{60}-1}[/tex]

=> [tex]\frac{17500\times0.00575\times(1.00575)^{60}}{(1.00575)^{60}-1}[/tex]

EMI = $345.70

Case 2:

p = 17500

r = [tex]4.9/12/100=0.004083[/tex]

n = [tex]5\times12=60[/tex]

Putting the values in formula;

[tex]\frac{17500\times0.004083\times(1+0.004083)^{60}}{(1+0.004083)^{60}-1}[/tex]

=> [tex]\frac{17500\times0.004083\times(1.004083)^{60}}{(1.004083)^{60}-1}[/tex]

EMI = $329.45

So, difference per month in payments will be :

[tex]345.70-329.45=16.25[/tex] dollars

Hence, Jordan will save $16.25 each month by choosing financing through the dealership.

All of the right triangles are similar by AA similarity, so corresponding side lengths are proportional. The ratio of the long leg to the short leg is the same for the two smaller triangles, for example:

  CP/AP = MP/CP

  CP/9 = 16/CP . . . . . fill in the given numbers

  CP² = 9·16 . . . . . . . multiply by 9·CP

  CP = 3·4 = 12 . . . . . take the square root

Now, you can use the Pythagorean theorem to find AC and/or CM.

  AC = √(9² +12²) = √225 = 15

  CM = √(12² +16²) = √400 = 20

In summary, CP = 12, AC = 15, CM = 20.

_____

Once you have CM, you can see these are 3-4-5 right triangles, so you can determine the other lengths by using these side ratios.

  3:4:5 = 9:12:15 = 12:16:20

The altitude CP is called the "geometric mean" of AP and MP. It is the square root of their product. This is true for any right triangle, not just one with sides in the ratio 3:4:5.

Answer:-(√3)/2, (√2)/2, -√3, and undefined

Step-by-step explanation:

There are two ways you can solve this.  One is with the Pythagorean identity:

sin²θ + cos²θ = 1

The other way is by knowing your unit circle.

1. From the unit circle, we know that cos θ = 1/2 at θ = π/3 and θ = 5π/3.  Since θ is in Quadrant IV, then θ = 5π/3.  sin (5π/3) = -(√3)/2.

We can check our answer using the Pythagorean identity:

sin²θ + cos²θ = 1

sin²θ + (1/2)² = 1

sin²θ + 1/4 = 1

sin²θ = 3/4

sin θ = ±(√3)/2

Since sine is negative in Quadrant IV, sin θ = -(√3)/2.

We can repeat these steps for the other questions.

2. sin θ = (√2)/2 at θ = π/4 and θ = 3π/4.  Since θ is in Quadrant I, θ = π/4.  Therefore, cos θ = (√2)/2.

3. cos θ = -1/2 at θ = 2π/3 and θ = 4π/3.  Since θ is in Quadrant II, θ = 2π/3.  Therefore, sin θ = (√3)/2, and tan θ = sin θ / cos θ = -√3.

4. sin θ = -1 at θ = 3π/2.  Therefore, cos θ = 0.  tan θ = sin θ / cos θ, so tan θ is undefined.

1. sinθ = √3/2, 2. cosθ = √2/2, 3. tanθ = -√3, 4. tanθ is undefined.

1. Given that cosθ=1/2 and θ terminates in Quadrant IV, we can use the Pythagorean identity sin^2θ + cos^2θ = 1 to find sinθ. Substitute the value of cosθ into the equation: sin^2θ + (1/2)^2 = 1. Solve for sinθ: sinθ = ± √(1 - (1/4)) = ± √(3/4) = ± √3/2. Since θ terminates in Quadrant IV, sinθ is positive. Therefore, sinθ = √3/2.

2. Given sinθ=(√2)/2 and θ terminates in Quadrant I, we can again use the Pythagorean identity sin^2θ + cos^2θ = 1 to find cosθ. Substitute the value of sinθ into the equation: (√2/2)^2 + cos^2θ = 1. Solve for cosθ: cosθ = ± √(1 - (1/2)). Since θ terminates in Quadrant I, cosθ is positive. Therefore, cosθ = √(1 - (1/2)) = √(1/2) = 1/√2 = √2/2.

3. Given cosθ=-1/2 and θ terminates in Quadrant II, we can find sinθ using the Pythagorean identity sin^2θ + cos^2θ = 1. Substitute the value of cosθ into the equation: sin^2θ + (-1/2)^2 = 1. Solve for sinθ: sinθ = ± √(1 - (1/4)) = ± √(3/4) = ± √3/2. Since θ terminates in Quadrant II, sinθ is positive. Therefore, sinθ = √3/2. Now, we can find tanθ using the relationship tanθ = sinθ / cosθ. Substitute the values of sinθ and cosθ into the equation: tanθ = (√3/2) / (-1/2) = -√3.

4. Given sinθ=-1 and 0≤θ<2π radians, we can find cosθ using the Pythagorean identity sin^2θ + cos^2θ = 1. Substitute the value of sinθ into the equation: (-1)^2 + cos^2θ = 1. Solve for cosθ: cos^2θ = 1 - 1 = 0. Since 0^2 = 0, cosθ = 0. Now, we can find tanθ using the relationship tanθ = sinθ / cosθ. Substitute the values of sinθ and cosθ into the equation: tanθ = -1 / 0 = undefined.
