Answer:

See below

Step-by-step explanation:

cos  2pi/3   =    -1/2

sin   2pi/3   =     sqrt (3)/2

cos   1 pi/6  =     sqrt(3)/2

sin   11 pi/6  =    - 1/2

so when you put in these values in  you will have :

(2*8) * (-1/2 + sqrt (3)/2 i )( sqrt(3)/2) + i (-1/2) )

= 16 ( - sqrt (3)4  + 1/4 i + 3/4 i - sqrt(3)/4  i^2 )        rememember i^2 =  - 1

= 16 ( 1/4  i  + 3/4  i )

= 16 i

Clayman is 10 years old and Ato is 15 years old

Let the age of Clayman be x

Let the age of Ato be y

If the sum of ages of Clayman and Ato is 25 years. then;

x + y = 25

x = 25 - y ...... 1

In five years time;

Age of Clayman = x + 5

Age of Ato = y + 5

If in five years' time, the age of Ato will twice the age of Clayman now, then;

y+5 = 2x ............. 2

Substitute equation 1 into 2

y +5 = 2(25-y)

y + 5 = 2(30 - y)

y + 5 = 50 - 2y

3y = 45

y = 15

Since x + y = 25

x = 25 - 15

x = 10

Therefore Clayman is 10 years old and Ato is 15 years old

Is the second expression written correctly?  It reduces to y>-2, since no x is in the equation.

Step-by-step explanation:

We can graph the two equations.  See attached image.  If y>2 is the correct expression, all points to the right.

If the equation was meant to read y=-3x+1, then graph the revised expression.

The value of f(x) = 3x² - 2x at x = 4 is 40.

The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x. Mapping or transformation is used to denote a function in math.

Here, the given function;

    f(x) = 3x² - 2x

put the value of x = 4, we get

     f(4) = 3 X 4² - 2 X 4

     f(4) = 3 X 16 - 8

      f(4) = 48 - 8

     f(4) = 40

Thus, the value of f(x) = 3x² - 2x at x = 4 is 40.

Answer:

[tex]LM = 35cm[/tex] and [tex]m \angle H = 98^o[/tex]

Step-by-step explanation:

For this problem, it is critical to understand what the opening statement means.

[tex]Quadrilateral GHJK \cong quadrilateral LMNP[/tex] means that each pair of corresponding sides between shapes are congruent (they have equal length), and each pair of corresponding angles between shapes are congruent (they have equal measure -- or same number of degrees when measured with a protractor).

So, it's important to be able to determine which pairs are the corresponding parts.  When the congruence is given like [tex]Quadrilateral GHJK \cong quadrilateral LMNP[/tex]  the letters are in a particular order.  That order explains the order in which the shape is drawn out, and they put them in the same order for both shapes to mean that those are the letters that correspond with each other.

So, the first letter of each are a corresponding pair, the second letter of each are a corresponding pair, ... etc

In other words, point G and L correspond, point H and K correspond, etc.

To find the corresponding sides, the sides for these shapes are defined by a two adjacent letters (two letters next to each other in the name, or ... as it wraps around the end of the name... the first and last letter).

[tex]\overline{GH} \cong \overline{LM}\\ \overline{HJ} \cong \overline{MN} \\\overline{JK} \cong \overline{NP}\\\overline{KG} \cong \overline{PL}[/tex]

While all of that is true, we only have a few sides with any information in them.  Notice that side GH in the first shape, and sides PL & LM in the second shape are the only sides with anything written.  So, we just need to determine which sides correspond (and thus, are congruent), so that we know how to move forward.  Looking at the list of congruent sides above, we see that  [tex]\overline{GH} \cong \overline{LM}[/tex]

Since the sides (line segments) are congruent, their lengths are equal

[tex]GH = LM[/tex]

...so we can substitute the expressions for each angle into the equation and solve for the unknown value "x"

[tex]GH = LM\\(4x+3)=(6x-13)[/tex]

[tex](4x+3)+13=(6x-13)+13\\4x+16=6x[/tex]

[tex](4x+16)-4x=(6x)-4x\\16=2x[/tex]

divide both sides by 2

[tex]\frac{16}{2}=\frac{2x}{2}\\8=x[/tex]

So, to find the length, LM, we just need to look back at the expression for LM:

[tex]LM = 6x-13\\LM = 6(8)-13\\LM = 48-13\\LM = 35[/tex]

remembering that the lengths are measured in centimeters (as indicated on the diagram): [tex]LM = 35cm[/tex]

To find the corresponding angles, the angles for these shapes are defined by a single letter, so since the points correspond in order, the names of the shapes tell which angles are congruent.

[tex]\angle G \cong \angle L\\\angle H \cong \angle M\\\angle J \cong \angle N\\\angle K \cong \angle P[/tex]

While all of that is true, we only have a few angles with any information in them.  Notice that ∠H in the first shape, and ∠L & ∠M in the second shape are the only angles with anything written.  So, we just need to determine which angles correspond (and thus, are congruent), so that we know how to move forward.  Looking at the list of congruent angles above, we see that  

[tex]\angle H \cong \angle M[/tex]

Since the angles are congruent, their measures are equal

[tex]m\angle H = m\angle M[/tex]

...so we can substitute the expressions for each angle into the equation and solve for the unknown value "y"

[tex]m\angle H = m\angle M\\(9y+17)=(11y-1)[/tex]

subtract 1 from both sides

[tex](9y+17)+1=(11y-1)+1\\9y+18=11y[/tex]

subtract 9y from both sides

[tex]\\(9y+18)-9y=(11y)-9y\\18=2y[/tex]

divide both sides by 2

[tex]\frac{18}{2}=\frac{2y}{2}\\9=y[/tex]

So, to find angle H, we just need to look back at the expression for the measure of angle H:

[tex]m\angle H = 9y+17\\m\angle H = 9(9)+17\\m\angle H = 81+17\\m\angle H = 98[/tex]

remembering that the angle is measured in degrees (as indicated on the diagram): [tex]m \angle H = 98^o[/tex]

Answer:1 is exponential. 2 is linear. 3 is neither. 4 is linear. 5 is linear. 6 is exponential. 7a is  exponential. I think 7b could be 10x + y = 10 but I'm not too sure. 7c is (8,4).

Step-by-step explanation:1. the coordinates are moving in an exponential way or something im not sure the correct wording but that is what exponential graphs look like. 2 is a straight line so it is linear. 3 is neither because the graph isn't exponential or linear. 4 is linear because the coordinates are subtracting at the same number. 5 is linear for the same reason at 4. 6 is exponential because the coordinates are multiplied by 2 each time. 7a is exponential because the coordinates are divided by 2 each time. 7b I'm not sure on. 7c is 8/4 because August is the 8th month and the month before (7) is 8 so 8 divided by 2 equals 4. So the 8th month would have to be 4. I hope that helps!

The equation formed by the given condition is 960.5 + 35.75p ≤ 1818.50 and the number of players they can bring is a maximum of 24.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Given that,

The total amount that can be spent = $1818.50

Rent of bus = $960.50

Cost per player = $35.75/player

So,

Cost of bus + Cost per player × number of players ≤ The total amount that can be spent

960.50 + 35.75p ≤ 1818.50
