Answers:

[tex]i^{157} = i\\\\i^{315} = -i\\\\i^{102} = -1\\\\i^{76} = 1\\\\[/tex]

=====================================================

Explanation:

By definition, [tex]i = \sqrt{-1}[/tex]

Squaring both sides gets us [tex]i^2 = -1[/tex]

Then multiply both sides by i to get [tex]i^3 = -i[/tex]

Repeat the last step and you should get [tex]i^4 = -i^2 = -(-1) = 1[/tex]

---------------

Notice we have this pattern going on:

[tex]i^0 = 1\\\\i^1 = i\\\\i^2 = -1\\\\i^3 = -i\\\\i^4 = 1\\\\[/tex]

Once we reach i^4, we start the process over again.

It repeats every 4 terms.

This means we'll divide the exponent over 4 and look at the remainder. We ignore the quotient completely.

157/4 = 39 remainder 1

That remainder 1 is the exponent of the simplified term

[tex]i^{157} = i^1 = i[/tex]

---------------

Similarly,

315/4 = 78 remainder 3

So [tex]i^{315} = i^3 = -i[/tex]

---------------

102/4 = 25 remainder 2

[tex]i^{102} = i^2 = -1[/tex]

----------------

76/4 = 19 remainder 0

[tex]i^{76} = i^0 = 1[/tex]

Answer:

Question (a)

Midpoint of a line segment:

[tex]M=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

Given:

[tex]\implies \textsf{midpoint of }JL=\left(\dfrac{-2+4}{2},\dfrac{2+0}{2}\right)=(1,1)[/tex]

Given:

[tex]\implies \textsf{midpoint of }MK=\left(\dfrac{3-1}{2},\dfrac{7-5}{2}\right)=(1, 1)[/tex]

Question (b)

Find slopes (gradients) of JL and MK then compare.  If the product of the slopes of JL and MK equal -1, then JL and MK are perpendicular.

[tex]\textsf{slope }m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Given:

[tex]\implies \textsf{slope of }JL=\dfrac{0-2}{4+2}=-\dfrac13[/tex]

Given:

[tex]\implies \textsf{slope of }MK=\dfrac{-5-7}{-1-3}=3[/tex]

[tex]\textsf{slope of }JL \times \textsf{slope of }MK=-\dfrac13 \times3=-1[/tex]

Hence segments JL and MK are perpendicular

Answer:

Step-by-step explanation:

Place : y+x=2 <==> y = 2-x

and now replace y with the x-expression:

2x-(2.x)=-4 <==> 2x-2+x= 4 <==> 3x-2 =4 <==> 3x = 6 --> x = 2

and y = 2-x so y = 2-3 = -1

so the solution is S = {(2; .1)}

Answer:

62 square units

Step-by-step explanation:

Top or bottom is 5 x 3, surface area is 15

front or back is 3 x 2, area = 6

left or right is 5 x 2, area = 10

so total area is 2*(15 + 6 + 10) = 62 square units

The total of people in the Cinco de Mayo parade if there are 140 dancers and these represent the 35% is 400.

This information can be known by using the information given about the dancers and a rule of three.

In this case, we know 140 dancers are equal to 35%. This means:

140 = 35 %

 x    = 100 %

x= 140 x 100 = 35

x= 14000 / 35 = 400

This means 400 are the total people in the parade.

A rhombus have all its side equal to each other . Therefore, the value of x in the rhombus QRST is 9

Therefore,

6x - 5 = 4x + 13

6x - 4x = 13 + 5

2x = 18

divide both sides by 2

2x / 2 = 18 / 2

x = 9

4:7

Step-by-step explanation:

The ratio of the number of corn tortillas to flour tortillas is 3:4. So this means there are at least 3 corn tortillas and 4 flour tortillas.

We need to add 3 and 4 to see the simplified total of tortillas. 3+4=7.

There is a total of 7 tortillas regardless of their type.

Now we just need to compare this with the number they already gave us for flour tortillas, which is 4.

4:7 or 4 flour:7 in total

The ratio of flour tortillas to total tortillas is 4:7.

Answer:

value of a is -19

value of b is 10

Step-by-step explanation:

Given

p(x) = 6x³ + ax² + 9x + b

Since it is given (x-2) & (2x-1) are the factors of given polynomial p(x) .

So, x = 2 & x = -1/2 are the solutions of given polynomial .

when x = 2

p(2) = 6(2)³ + a(2)² + 9 (2) + b = 0

p(2) = 6×8 + 4a + 18 + b = 0

p(2) = 48 + 4a + 18 + b = 0

p(2) = 66 + 4a + b = 0

4a + b = -66 -------(i)

Now ,

when x = -½

p(-½) = 6(-½)³ + a (-½)² + 9(-½) + b = 0

6 × (-⅛) + a/4 - 9/2 + b = 0

-3/4 + a/4 - 9/2 + b = 0

-3 + a -18+4b/4 = 0

-21 + a + 4b = 0

a + 4b = 21 -------(ii)

Now, multiplying the equation (ii) by 4 we get

4a + 16b = 84 -----(iii)

Substracting equation (i) from (iii) we obtain

15b = 150

b = 150/15

b = 10

Now, putting the value of b = 10 in equation (ii) we get

a + 40 = 21

a = 21-40

a = -19

So, the required value of a & b are 10 & -19 respectively .

Answer:

Hema - 9 stickers Rekha - 21 stickers

Step-by-step explanation:

Total Number of stickers given - 30

Ratio of stickers divided between Hema and Rekha - 3:7

Let the number of stickers Hema have be 3x

Let the nunber of stickers Rekha have be 7x

According to question,

3x+7x=30

10x=30

x=30/10

x=3

Therefore,

Number of stickers Hema got = 3x

= 3*3

= 9

Number of stickers Rekha got = 7x

= 7*3

= 21

Hence,

Hema will get 9 stickers

Rekha will get 21 stickers

Answer:

1: y=-2x+5

Step-by-step explanation:

When two lines are parallel, the slopes are equivalent.

First, you have to turn 2x+y=7 into standard form.

2x+y=7

y=-2x+7

The slope is -2 so then you find an answer choice with -2 as the slope.

Turn all the answers into standard form first:

2: x+2y=4

2y=-x+4

y=-1/2x+4  Not choice 2 since the slope is -1/2.

3: y-2x=2

y=2x+2 Not choice 3 because the slope is positive 2.

Therefore, choice 1 is parallel to equation 2x+y=7.

I believe the answer to your question is 34°

Answer: 47.5 cm^2

Step-by-step explanation:

Tony's mistake is that he added the area of the rectangle and triangle. Instead you should subtract the area of the triangle from the rectangle.

1. The area of the rectangle is 5*11 = 55 cm^2

2. The area of the nonshaded triangle is 5*3*(1/2) = 7.5 cm^2

3. The area of the shaded region is the area of the rectangle minus the area of the triangle. This equals 55 - 7.5 cm^2 = 47.5 cm^2

(3 x 5)^4 x (2 x 3)^5 x (2 x 5)^7

= 3^4 x 5^4 x 2^5 x 3^5 x 2^7 x 5^7

= 2^(5 + 7) x 3^(4 + 5) x 5^(4 + 7)

= 2^12 x 3^9 x 5^11

so x = 12, y = 9, z = 11
