Answer:

3

Step-by-step explanation:

1+ω+w²=0

ω³=1

(1-ω)(1-ω²)=1-ω²-ω+ω³

=1-ω-ω²+1

=2+1-1-ω-ω²

=3-(1+ω+ω²)

=3-0

=3

Answer:

8.6

Step-by-step explanation:

To find the length of a hypotenuse, use the formula a²+b²=c² where c is the hypotenuse. In this case, it's 5²+7²=c². Then do the calculations and take the square root to find c. 25 + 49 = c². 74=c². The square root of 74 to the nearest 10th is 8.6

Given:

The ratio is [tex]\dfrac{3}{1}[/tex].

To find:

Inverse tangent of the given ratio.

Solution:

We know that,

Inverse tangent of the ratio [tex]\dfrac{3}{1}[/tex] = [tex]\tan^{-1}\dfrac{3}{1}[/tex]

                                                 = [tex]\tan^{-1}3[/tex]

Using scientific or graphing calculator, we get

Inverse tangent of the ratio [tex]\dfrac{3}{1}[/tex] = [tex]71.565^\circ[/tex]

Round to the nearest degree

Inverse tangent of the ratio [tex]\dfrac{3}{1}\approx 72^\circ[/tex]

Therefore, the correct option is C.

Answer:

C

Step-by-step explanation:

Darby's equation in slope-intercept form: y = 4x + 6

Where,

Slope (m) = 4

y-intercept (b) = 6

Let's find the slope (m) and y-intercept (b) of the line Samuel graphed using the values of the given table.

Slope (m) using (0, 6) and (2, 14)

Slope (m) = ∆y/∆x = (14 - 6)/(2 - 0) = 8/2

Slope (m) = 4

y-intercept (b) = 6, because at x = 0, y = 6. This is where the line intercepts the y-axis.

Now, we can see that both functions has the same slope (m) = 4, and the same y-intercept (b) = 6

Both will have the same line.

Answer:

[tex]77 {m}^{2} [/tex]

Step-by-step explanation:

Given,

Height of the parallelogram = 7m

Base of the parallelogram = 11 m

Therefore, area of the parallelogram = b × h

= 7m × 11m

[tex]77 {m}^{2} (ans)[/tex]

Answer:

option C: 120

Step-by-step explanation:

total marks = 5× 100 = 500

The simplification of the given expression using laws of exponents is: 80x⁸

Some of the laws of exponents are:

- When multiplying by like bases, keep the same bases and add exponents.

- When raising a base to a power of another, keep the same base and multiply by the exponent.

- If dividing by equal bases, keep the same base and subtract the denominator exponent from the numerator exponent.  

The expression we want to solve is given as:

4x²√(5x⁴) * 3√(5x⁸)

Using the concept of laws of exponents, this simplifies as:

4x² * x² * 3x⁴ * 5

= 80x⁸

Answer:

Square, multiply b, add, quadratic equation

Step-by-step explanation:

Answer:

25%

Step-by-step explanation:

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

Total shaded checker board (T) = 32

Shaded checker board with pieces (S) = 8

Percentage of Shaded checker board with pieces =?

We can obtain the percentage of checker board with pieces as follow:

Percentage of Shaded checker board with pieces = Shaded checker board with pieces / Total shaded checker board × 100

= S / T × 100

= 8 / 32 × 100

= 25%

Therefore, percentage of Shaded checker board with pieces is 25%

Answer:

Area of circle = pie r²

= 3.14 × 2.25

=7.065

Answer: 7.07cm²

Step-by-step explanation: diameter=3

radius=d/2

          =3/2

          =1.5cm

area=πr²

       =22/7 x 1.5 x 1.5

       =22/7 x 2.25

       =99/2 ÷ 7

       =99/2 x 1/7

       =99/14

Answer:

x=3

Step-by-step explanation:

AB+BC>AC

2x + 3 + x + 1 > x + 10

we correct like terms

2x + x + 3 + 1> x+ 10

3x + 4> x + 10

3x - x > 10-4

2x > 6

divide both sides by 2

2x÷2 > 6÷2

x = 3

Step-by-step explanation:

y = x^2

X increased by 10% = 1.10x

(1.10x)^2 = 1.21x^2

y increases by 21%

Answer:

Slope = 2

Step-by-step explanation:

Find the slope by using the slope equation:

[tex]\frac{y^2 - y^1}{x^2 - x^1}[/tex]

Plug in the numbers to the slope equation:

[tex]\frac{8 - (-8)}{2 - (-6)}[/tex]

Which is equal to:

[tex]\frac{16}{8}[/tex]

Which is simplified to:

2.

Answer:

Step-by-step explanation:

[tex]L=4W-2\\ \\ P=2(L+W)\\ \\ 2(4W-2+W)=36\\ \\ 5W-2=18\\ \\ 5W=20\\ \\ W=4,\ L=14\\ \\ A=4(14)=56cm^2[/tex]

Answer:

L=4W-2

P=2L+2W

36= 2(4W-2)+2W

36= 8W-4 +2W

36= 10W-4

36+4=10W

40=10W

40/10=W

W=4

L=4(4)-2

L=14

AREA =L(W)

AREA = 4X14

AREA =48 cm

Answer:

D. 1/11.

Step-by-step explanation:

There are 12 pencils in the case.

Prob( first one is sharpened) = 4/12 = 1/3

Prob(second is sharpened) = 3/11

Prob(both sharpened) = 1/3 * 3/11

= 3/33

= 1/11.

The probability is 1/11 that both pencils will be sharpened which is the correct option(D).

The probability is defined as the possibility of an event being equal to the ratio of the number of outcomes and the total number of outcomes.

Given that,

Bonnie has 4 sharpened and 8 unsharpened pencils

So, there is a total of 12 pencils in the pencil case.

Let, the probability first one is sharpened is P(E₁)

The probability second one is sharpened is P(E₂)

P(E₁) = 4/12 = 1/3

P(E₂) = 3/11

Required probability both sharpened P(E) = P(E₁)×P(E₂)

Required probability both sharpened P(E) = 1/3 × 3/11

Required probability both sharpened P(E) = 3/33

Required probability both sharpened P(E) = 1/11.

Hence, the probability is 1/11 that both pencils will be sharpened.
