So here,

x°+100°+( x+12)°= 180°(being in a straight line)

2x° + 112°=180°

2x°=180-112°

x=68/2

x=34°

Negative plus positive is negative or positive depending on the magnitude of numbers. Let's understand the negative plus the positive number. Explanation: ... If we add a negative integer, the value of the given number will decrease and if we add a positive integer the value will increase.

Step-by-step explanation:

So let classify each function.

38 is a quadratic because it has a leading variable raised to the 2nd degree.

Quadratics always accept all x values positive or negative so the domain

Quadratics lowest range is it vertex. The vertex of a typically quadratic is 0 because when we have the function

[tex] {x}^{2} [/tex]

we have no value after it so 0 is the lowest number.

However we have

[tex] {x}^{2} - 9[/tex]

So this means that our lowest value will be -9.

We include that point as well. The leading coeffceint is positive so it approach infinity so the range is

39 is a square root function because it has the square root symbol. Remeber that we can't take the square root of a negative number i.e( we can but it isn't graphable on a Cartesian plane). So this means x has to be greater than or equal to zero. We can take the square root of 0.

So set the equation inside the radical equal to zero.

[tex]x - 4 = 0[/tex]

[tex]x = 4[/tex]

So this means the domain is

In a square root function, we restrict our domain to only positive number so the range is

[0,♾)

Answer:

The Earth's orbit makes a circle around the sun. At the same time the earth orbits around the sun, it also spins. In science, we cal that rotating on its axis. Since the earth orbits the sun AND rotates on its axis at the same time we experience seasons, day and night, and changing shadows throughout the day.

Answer:

y = 4

Step-by-step explanation:

If 3 is x than you can substitute x for 3. y = 3 + 1. Then when you add  y = 4

y = x+1

y = 3+1

y= 4

that's how you solve it... Good luck

Step-by-step explanation:

The radius of the orbit is r = 1150 km + 6400 km = 7550 km or

[tex]r = 7.55×10^6\:\text{m}[/tex]

and it takes 140 minutes to complete 1 revolution. This is the same aa

[tex]140\:\text{min}×\dfrac{60\:\text{s}}{1\:\text{min}} = 8400\:\text{s}[/tex]

The linear speed of the satellite then is simply equal to the orbital circumference divided by the orbital period T or

[tex]v = \dfrac{2\pi r}{T}[/tex]

[tex]\:\;\:\:=\dfrac{2\pi(7.55×10^6\:\text{m})}{8.4×10^3\:\text{s}}[/tex]

[tex]\:\:\:\:=5647.4\:\text{m/s}[/tex]

In km/min, this is

[tex]v = \dfrac{2\pi(7550\:\text{km})}{140\:\text{min}} = 338.8\:\text{km/min}[/tex]

Answer:

Slope = -3

Step-by-step explanation:

Answer:

Slope is -3

Step-by-step explanation:

Find two points on the graph where the line hits both corners of the graph first. ( The line has to go through a corner )

Two points on the graph: ( -2,6 ) and ( 2, -6 )

The first values are X-values ( -2, 2 ) It does left to right

The second values are Y-values ( 6,-6 ) It goes up and down

So to find the slope of a line you get two points and you do this formula

( y2-y1 ) / ( x2-x1 )

So that means

( -6 - 6 )

-------------     =   -12

( 2 - -2 )           -------

                         4

-12 / 4 = -3

Answer:

Step-by-step explanation:

Consider a zero at x=1.

If it has multiplicity 1, the corresponding factor is (x -1). Now consider the sign of that factor for x = 1.1. The value is (1.1 -1) = 0.1, a positive number.

When the value of x is 0.9, the factor is (0.9 -1) = -0.1, a negative number.

This tells you that values to the left of a zero make the factor(s) associated with that zero be negative. For x-values to the right of the zero, the factor(s) will be positive.

If the multiplicity is even, the product of those factors is positive on either side of the zero. (A negative number to an even power is a positive number.) That is, the graph will not change sign from one side of an even-multiplicity factor to the other. At an odd-multiplicity factor, the graph changes sign.

__

For the problem at hand, the only even-multiplicity factor is (x -1), so the graph will not change sign at x=1. It will touch the axis (be tangent to the x-axis), but will not cross. The other zeros have odd multiplicity (1 or 3), so the graph will change sign there.

It is worthwhile to note that the higher the multiplicity, the "flatter" the graph is at the zero. You can see this in the attachment by comparing the shape of the graph at x=6 with the shape at x=2 (also an upward zero crossing).

_____

Additional comment

You may wonder why the curve is below the x-axis at x=1 when the product of the factors in that neighborhood is always positive. The reason is that there are an odd number of zeros to the right of x=1, so the product of those factors is negative.

Answer:

b. Slope: 125/2

Point-slope form:

y-400 = 125/2(x-8)

y = 125/2+392

e. 767 consumers

Step-by-step explanation:

b. The slope is 125/2

Point-slope form:

Slope: 125/2 and point (8,400)

y-y=m(x-x)

Point slope form:

y-400=125/2(x-8)

y = 125/2 x + 392

y = (125/2)(6) + 392

y = 767

14%

The answers of questions which includes the quantity 43 is 6.45 ,  129 , 5.16 , 40.56 % and 13.95%  respectively .

The symbol (%) is used to denote percentage. Similarly, percentage is sometimes denoted by an abbreviation 'pct. ' For example, we can express 50 percent as 50% or 50 pct. Percentages are written inform whole numbers, fractions or decimals. For example, 4%, 75%, 0.6%, 0.25%, 3/5% etc.

According to the question

Each question includes the quantity 43 .

A. Number that is 15% of 43 :

C. 12% of what number is 43?

12% of 43

= [tex]\frac{12}{100} * 43[/tex]

= 5.16

D. 43 is what percent of 106?

Let percent be x

i.e

106 * x% = 43

[tex]1.06x = 43[/tex]

x = 40.56%

E. What percent of 43 is 6?

Let percent be x

i.e

43 * x% = 6

0.43x = 6

x = 13.95 %

Hence, The answers of questions which includes the quantity 43 is 6.45 ,  129 , 5.16 , 40.56 % and 13.95%  respectively .
