Answer:

Domain: [–4, 4] Range: [0, 4]

Since the circles are closed that means the value will be in brackets.

Answer:

Perimeter: 52 Area: 181-16i?

Step-by-step explanation:

Perimeter

The formula for perimeter is 2l+2w, so you plug in the binomials they give you:

2(11-4i)+2(15+4i)

expand:

22-8i+30+8i

combine like terms (which cancels out 8i and -8i):

22+30=52

Area

"i" is not a real number and thus should not be part of the area here, meaning this answer as it is is wrong and I don't know how one would change that.

Here's what I did to get 181-16i, in any case:

The formula for area is l*w, so I plugged in the numbers:

(11-4i)(15+4i)

expanded:

165+44i-60i-16i*i

and combined like terms:

181-16i

*i is [tex]\sqrt{-1}[/tex], so [tex]i^{2}[/tex]=-1 and -1*-16=16.

sharia has a full time job and earns 475$ each week but she starts looking for ways to increase her weekly earnings . sharia finds a part-time job which would pay 11$ per hour. How many hours would sharia need to work each week at the part-time job in order to raise total weekly income to at least $600?

Answers

Answer:

12 hours

Step-by-step explanation:

Full time job:

Earning per week = $475

Part time job :

Earning per hour = $11

Number of working hours per week at per time job to increase weekly earning to atleast $600 ;

Let number of hours = h

Full time earning + earning per hour * (number of hours) ≥ 600

$475 + ($11 * h) ≥ 600

$475 + $11h ≥ 600

11h ≥ 600 - 475

11h ≥ 125

h ≥ 125 / 11

h ≥ 11.36

Hence, sharia will need to work for 12 hours per week

Find the values of X and why in the following equation.

(x+yi)+(4+9i)=9-4i

Answers

Answer:

The values of x and y are x = 5 and y = -13B

Step-by-step explanation:

If the complex numbers are A = (a + bi) and B = (c + di), then

A + B = (a + c) + (b + d)i

(a + c) is the real part(b + d) is the imaginary part

Let us solve the question

(x + yi) + (4 + 9i) = 9 - 4i

→ Add the real parts and the imaginary parts on the left side

∵ x, 4 are the real parts, and y and 9 are the imaginary parts

(x + 4) + (y + 9)i = 9 - 4i

→ Compare the two sides, and equate the like terms

∵ 9 is the real part and -4 is the imaginary part

x + 4 = 9

→ Subtract 4 from both sides

∴ x + 4 - 4 = 9 - 4

x = 5

y + 9 = -4

→ Subtract 9 from both sides

∵ y + 9 - 9 = - 4 - 9

y = -13

Answer:

x = 5 and y = -13

a 0, b >0, and c >0
a >0, b 0
a 0, and c >0
a 0, and c 0, b 0
a >0, b >0, and c <0

Answers

Answer:

False

Step-by-step explanation:

A nonlinear function that can be written on the standard form

ax2+bx+c,wherea≠0

is called a quadratic function.

All quadratic functions has a U-shaped graph called a parabola. The parent quadratic function is

y=x2

picture51

The lowest or the highest point on a parabola is called the vertex. The vertex has the x-coordinate

x=−b2a

The y-coordinate of the vertex is the maximum or minimum value of the function.

a > 0                   parabola opens up                    minimum value

picture52

a < 0                    parabola opens down              maximum value

picture53

A rule of thumb reminds us that when we have a positive symbol before x2 we get a happy expression on the graph and a negative symbol renders a sad expression.

The vertical line that passes through the vertex and divides the parabola in two is called the axis of symmetry. The axis of symmetry has the equation

x=−b2a

The y-intercept of the equation is c.

picture54

When you want to graph a quadratic function you begin by making a table of values for some values of your function and then plot those values in a coordinate plane and draw a smooth curve through the points.

Example

Graph

x=x2+2x+1

Make a table of value for some values of x. Use both positive and negative values!

Notice that we have a minimum point which was indicated by a positive a value (a = 1). The vertex has the coordinates (-1, 0)  which is what you will get if you use the formula for the x-coordinate of the vertex

x=−b2a=−22⋅1=−1

and that the line has an y-intercept of (0, 1) which could have been determined from the c-value which is 1.

If you have an absolute value of a that is greater than 1 the parabola will be narrower than the parental quadratic function. And the opposite that if you have a absolute value of a that is less than 1 then the parabola will be wider than the parental quadratic function.

The vertical parabola opens downward, has its vertex in the fourth quadrant, and y = ax + bx +c is the equation of this parabola given conditions none of them is true.

A nonlinear function that can be written on the standard form

[tex]ax^{2} + bx +c = 0 where (a\neq 0)[/tex]

a < 0                   parabola opens down     maximum value

find the value of a so tha the lines represented by 2x+3y=7 and x-8y=7 are perpendicular

Answers

Answer:

y = -5, x = 4

The value of a are; a = 6

Since Perpendicular lines have a slope that is negative reciprocal of each other. There product = -1

Solve both equations for y.

2x+3y=7                             x-8y=7

3y = ax + 7                                 8y = -4x + 2

y = ax/3 + 8/3                               y = -4x/8 + 2/8

y = a/3(x) + 8/3                              y = -1/2(x) + 1/4

Now we know that the slope;

y = -1/2(x)+ 1/4  is -1/2

Then the slope of y = a/3(x) + 8/3 is a/3.  

Now the value of "a" will make the lines perpendicular.

You know that one line slope is -1/2 so the other line slope is 2 because the slope are negative reciprocal.  

Thus remember that the slope is the coefficient of the x term.

Now   a/3 = 2 ; a = 6

Answer:

x = 7y = 4

Step-by-step explanation:

The diagonals of a parallelogram cross at their midpoints. This means the segments of each diagonal are equal in length:

  RT = PT

  x = 5x -28

  28 = 4x . . . . . add 28-x

  7 = x . . . . . . . .divide by 4

__

  QT = ST

  5y = 2y +12

  3y = 12 . . . . .subtract 2y

  y = 4 . . . . . . divide by 3

The values of x and y that make the figure a parallelogram are x=7 and y=4.
