Answer:

34

Step-by-step explanation:

The sum of the angles of a triangle is 180

26x+6 + 21x-1 +11x+1 = 180

Combine like terms

58x +6 = 180

Subtract 6 from each side

58x = 180-6

58x = 174

Divide by 58

58x/58 =174/58

x=3

We want <C

<C = 11x+1 = 11*3+1 = 33+1 = 34

Answer:

x = 47.2

Step-by-step explanation:

Since this is a right triangle, we can use  trig functions

cos theta = opp / hyp

cos x = 17/23

Taking the inverse cos of each side

cos ^-1 ( cos x) = cos ^-1 ( 17/25)

x =47.15635696

To the nearest tenth

x = 47.2

The rational equations after division is

a) A = ( 5x³ - 15x )

b) B = - ( 3x - 2 ) ( x - 4 ) ( 6 - 5x ) / ( 8x - 1 )

What is rational function equation?

A rational equation can be defined as an equation that involves at least one rational expression

A rational function is a function of the form f( x )=P( x ) / Q( x ) ,

f( x ) = P( x ) / Q( x ) , where P( x ) and Q( x ) are both polynomials.

A rational function f ( x )=P( x ) / Q( x )

f( x ) = P( x ) / Q( x ) may have a vertical asymptote

The domain is the set of all real numbers for which Q( x ) ≠ 0

Given data ,

a)

Let the first function be P ( x ) = ( 15x⁷ - 45x⁵ )

Let the second function be Q ( x ) = 3x⁴

On simplifying , we get

A = P ( x ) / Q ( x )

A = ( 15x⁷ - 45x⁵ ) / 3x⁴

A = 3x⁴ ( 5x³ - 15x ) / 3x⁴

On further simplification , we get

A = ( 5x³ - 15x )

b)

Let the first function be P ( x ) = ( 15x⁷ - 45x⁵ )

Let the second function be Q ( x ) = 3x⁴

On simplifying , we get

B = P ( x ) / Q ( x )

B = ( 3x - 2 ) ( x - 4 ) ( x - 4 ) ( 6 - 5x ) / ( 4 - x ) ( 8x - 1 )

B = - ( 3x - 2 ) ( x - 4 ) ( x - 4 ) ( 6 - 5x )  / ( x - 4 ) ( 8x - 1 )

On further simplification , we get

B = - ( 3x - 2 ) ( x - 4 ) ( 6 - 5x ) / ( 8x - 1 )

Hence , the rational equations are solved

Answer:

x=-1 or x=4

Step-by-step explanation:

First divide by 4 to get rid of the factor 4 at x², then you have:

x² - 3x - 4 = 0

to factor that, look for two numbers that when added, give -3, and when multiplied, give -4. This is guesswork but usually doable:

-4 + 1 = -3

-4 * 1 = -4

so -4 and +1 are our numbers.

The factorization is therefore: (x - 4)(x + 1) = 0, and the solutions are

x-4 = 0 or x+1 = 0, so x=4 or x=-1

Answer:

Mean.

Step-by-step explanation:

When a doctor analyzes the increase in systolic blood pressure caused by a certain chemo drug. The doctor would be more interested in studying the mean of the number of observed systolic blood pressures. As mean would give a better understanding of pressure since it involves the use of all observations. However, it is important to keep in mind that all the units should be considered for the average.

Answer:

the angle that is 110° and 30°

Step-by-step explanation:

The triangle is similar to triangle T is triangle III.

Thus, option (c) is correct.

In the given triangle,

Two angles are 110 and 40.

Using Angle sum property in given triangles as

Angle 1 + Angle 2 + Angle 3 = 180

110 + 40 + Angle 3= 180

150 + Angle 3= 180

Angle 3 = 180 - 150

Angle = 30

Thus, the angles are 110, 40 and 30.

Therefore, Triangle III is similar to triangle T.

Answer:

  A.  x^2 +(y -7)^2 = 625

  B.  S'(39, 20)

  C.  P'(19, 35)

  D.  C'(56.5, 17.5)

Step-by-step explanation:

Part A: The infinite number of points with those coordinates will be the solutions to the equation of a circle centered at Q with radius 25. The standard form equation of a circle with center (h, k) and radius r is ...

  (x -h)^2 +(y -k)^2 = r^2

For (h, k) = (0, 7) and r=25, the equation for the points of interest is ...

  x^2 +(y -7)^2 = 625

__

Part B: It is useful to recognize ΔROQ as a right triangle with sides that are the Pythagorean triple (7, 24, 25). (You can figure side RO using the Pythagorean theorem if you're not familiar with this triple.) This means the coordinates of R are (24, 0) and the horizontal distance to the line x=39 is 39-24=15 units.

If we name point X(39, 0), then triangle RXS' has sides RX = 15 and RS' = 25. We recognize these as a multiple of the Pythagorean triple (3, 4, 5), so we know that XS' = 20, (Again, you can figure this using the Pythagorean theorem if you're not familiar with the relevant triples.)

The coordinates of S' are (39, 20).

__

Part C:

Point S' is 15 right and 20 up from R. A vector at right angles to RS' will have the coordinates swapped, and one of them negated. Point P' will be 20 left and 15 up from point S', so ...

  P' = S' +(-20, 15) = (39, 20) +(-20, 15) =

  P' = (19, 35)

__

Part D: After rotation, the center (C) of the square is the midpoint of RP', so is ...

  C = (R +P')/2 = ((24, 0) +(19, 35))/2 = (43, 35)/2 = (21.5, 17.5)

Reflection over the line x=39 is accomplished by the transformation ...

  (x, y) ⇒ (2·39 -x, y)

  C(21.5, 17.5) ⇒ C'(78 -21.5, 17.5) = C'(56.5, 17.5)
