function or not a function?

Answer:

The nth term of the given sequence

[tex]a_{n} = a_{n-1} + (2n-1)[/tex]

Step-by-step explanation:

Explanation:-

Given sequence  -5,-4,-1,4,11,20,31

a₀ = -5

a₁ = a₀ +1 = -5 +1   = -4

a₂ = a₁ + 3 = -4+3  = -1

a₃ = a₂ + 5 = -1 +5 = 4

a₄ = a₃ + 7 = 4 + 7  =11

a₅ = a₄ + 9 = 11+9 = 20

a₆ = a₅ + 11 =  20+11 = 31

a₇ = a₆ + 13 = 31 +13 =44

and so on

The nth term of the given sequence

[tex]a_{n} = a_{n-1} + (2n-1)[/tex]

Answer:

We conclude that the slope of the graph of y = 5 x is 5.

Step-by-step explanation:

We know the slope-intercept form of the line equation

y = mx+b

where

Given the line

y = 5x

comparing with the slope-intercept form of the line equation

The slope of the line = m = 5

Therefore, we conclude that the slope of the graph of y = 5 x is 5.

Answer:

Option A. – 3

Step-by-step explanation:

From the question given above, the following data were obtained:

y = 3/4

xy² = 9/16

(x – 4) =?

Next, we shall determine the value of x. This can be obtained as follow:

y = 3/4

xy² = 9/16

x(3/4)² = 9/16

x (9/16) = 9/16

Divide both side by 9/16

x = 9/16 ÷ 9/16

x = 1

Finally, we shall determine the value (x – 4). This can be obtained as follow:

(x – 4)

x = 1

(x – 4) = 1 – 4

= – 3

Answer:

42

Step-by-step explanation:

All of a triangles angles equal 180 degrees. We know that one angle is 48 degrees and 1 angles is 90 degrees. We just have to subtract 138 from 180 to get 42.

Step-by-step explanation:

The conjugate of the complex root must also be a zero of the function if the complex root is already a zero.

Conjugate of -4 + 3i is -4 - 3i.

Hence -4 - 3i is also a zero of the function.

Answer:

-4 - 3i

Step-by-step explanation:

If a zero of a function is a+bi, there is at least one other zero, a-bi, called the conjugate.

Answer:

There is no x-intercept, only a y-intercept, which would be 1

Answer:

$1473

Step-by-step explanation:

cost of cloth= rs.950

He spent rs.150  for stitching a shirt

total cots= 950+150

total cost=1100

gain= rs.375

we know that

gain= selling price- cost price

substitute

375= selling price- 1100

selling price= 1100+373

selling price=$1473

Hence the selling price is $1473

Answer:

-5 or (-5,0)

Step-by-step explanation:

The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.

The solution is : the equation of the axis of symmetry is  x= -5 or (-5,0).

The parabola is a plane curve which is mirror symmetrical and is approximately U-shaped. It fits several superficial different mathematical descriptions.

here, we have,

we know that,

The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves.

Answer:

y- intercept = - 2.5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, - 7) and (x₂, y₂ ) = (5, - 25)

m = [tex]\frac{-25+7}{5-1}[/tex] = [tex]\frac{-18}{4}[/tex] = - 4.5 , then

y = - 4.5x + c

To find c substitute either of the 2 points into the equation

Using (1, - 7), then

- 7 = - 4.5 + c ⇒ c = - 7 + 4.5 = - 2.5

y- intercept c = - 2.5

Answer: x = 9

Step-by-step explanation:

x can be equal to 9.

Lets plug in 9 to the variable x, in this equation, x -3 = 6.

x - 3 = 6

9 - 3 = 6 (plugged in 9 for x)

So, x = 9.

im stuck on the same problem

The measure of QR, from the triangle TRQ is 16 units.

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.

Given that, triangle PML is similar to triangle TRQ.

From the given triangles.

ML/QR =PM/TR

(7x-9)/(2x+2) = 35/14

(7x-9)/(2x+2) = 5/2

2(7x-9)=5(2x+2)

14x-18=10x+10

4x=28

x=7

Then, QR=2x+2=16 units

Therefore, the measure of QR is 16 units.

Step-by-step explanation:

Answer:

TZ = 10 units

UY = 12 units

ZW = 11 units

Step-by-step explanation:

Point Z is the centroid of ΔTUV.

Since, centroid of a triangle is located on each median so that it divides each median in the ratio of 2 : 1

Therefore, TZ = 2(ZX)

TZ = 2(5) = 10 units

UY = UZ + ZY

     = UZ + [tex]\frac{1}{2}(UZ)[/tex]

     = [tex]\frac{3}{2}UZ[/tex]
