If the two sides of the triangle are equal then these two triangles are similar. The sides EF and GF are congruent to each other. Then the correct option is D.

Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.

In ΔEDF and ΔGDF

DF = DF = radius (common side)

ED = GD = radius

If the two sides of the triangle are equal then these two triangles are similar.

Thus, EF and GF are congruent to each other.

The equation of the circle can be written in standard form and in a general form

The center of the circle is (-4,6) and the radius is [tex]\sqrt{23[/tex]

The equation of the circle is given as:

[tex]x^2 + 8x + y^2 - 12y = -29[/tex]

Rewrite as:

[tex]x^2 + 8x + k - k + y^2 - 12y + k - k= -29[/tex]

Express k as the square of the half of the coefficients of x and y.

So, we have:

[tex]x^2 + 8x + (4)^2 - (4)^2 + y^2 - 12y + (6)^2 - (6)^2= -29[/tex]

Evaluate the exponents

[tex]x^2 + 8x + 16 - 16 + y^2 - 12y + 36 - 36 = -29[/tex]

Collect like terms

[tex]x^2 + 8x + 16 + y^2 - 12y + 36 = -29 + 16 + 36[/tex]

Express as perfect squares

[tex](x + 4)^2 + (y - 6)^2 = -29 + 16 + 36[/tex]

[tex](x + 4)^2 + (y - 6)^2 = 23[/tex]

The standard equation of a circle is:

[tex](x - a)^2 + (y - b)^2 + r^2[/tex]

Where:

Center = (a,b)

Radius = r

So, we have:

Center = (-4,6)

Radius = [tex]\sqrt{23[/tex]

Hence, the center of the circle is (-4,6) and the radius is [tex]\sqrt{23[/tex]

Answer: A.

I would say that it would have to be A. because it seems like B has all of the dots a little higher than the line while on A they seem closer packed into the line.

Step-by-step explanation:

The distance of the image from the lens V=22.5cm and the height of the image h=6.25cm.

It is given that

Hieght of an object H = 5cm

Distance of an object =18cm

Focal lenght of lens = 10cm

As we know that the lens formula is given by

[tex]\dfrac{1}{f} =\dfrac{1}{v} +\dfrac{1}{u}[/tex]

[tex]\dfrac{1}{v} =\dfrac{1}{10} -\dfrac{1}{18}=\dfrac{8}{180}[/tex]

so now

[tex]v= \dfrac{180}{8} =22.5\ cm[/tex]

Now to find the height of the image

[tex]\rm magnification =\dfrac{v}{u} =\dfrac{-Image\ Hieght }{object\ height}[/tex]

[tex]\rm magnification =\dfrac{22.5}{18} =\dfrac{-x}{5}[/tex]

[tex]x=-6.25\ cm[/tex]

Thus the distance of the image from the lens is V=22.5cm and the height of the image h=6.25cm.

Answer:

a) Red = 0.2 Blue= 0.4 and White =0.4

b) 90 counters in total

Step-by-step explanation:

a)Firstly we know that the probability of mutually exclusive events is equal to 1 and the question states that the probability of blue and white counter is the same so we subtract 1-0.2 = 0.8 and we divide that by 2 as a result 0.4 .

b) P= Favourable outcomes / total number of outcomes

P(red) = 0.2

total number of red counters = 18

0.2 = 18/t cross multiplying have 0.2t= 18

Dividing throughout by 0.2 having 90

How many footballs will be needed for 48 players?

Solve:

Since there are 2 balls for every 12 players..

Let's b = balls and P = Players

2b = 12p

4b = 24p

6b = 36p

8b = 48

Hence, we can conclude that there will be 8 footballs needed for 48 players

Answer:

8 balls

Step-by-step explanation:

We can use ratios to solve.

2 balls             x balls

-------------    = -----------------

12 players        48 players

Using cross products

2 * 48 = 12 *x

96 = 12x

Divide each side by 12

96/12 =12x/12

8=x

Answer:

508.68cm^2

Step-by-step explanation:

this is a semicircle, so first get the whole circle by s=

[tex]\pi \: r {}^{2} [/tex]

so it said you should plug in 3.14 for pi,

3.14×18^2=1017.36

and semicircle should be the half of it, which is 508.68 cm^2

Answer:

127.17 cm²

Step-by-step explanation:

The area of a circle of radius r is given the the formula below.

A = πr²

Since you have a semicircle, divide the area of a circle by 2.

A[semicircle] = πr²/2

A[semicircle] = 3.14 × (9 cm)² / 2 = 127.17 cm²

Answer: 127.17 cm²

You are correct. Remember to include the units. In this case, it is cm².

Answer:

Part A = $180

Part B = $104

Step-by-step explanation:

Part A:

51 x 4 = 180

Part B:

You do 130÷5=26

26 x 4 = 104

Answer:

$180 for the coat, $104 for the boots

Step-by-step explanation:

first: percent = decimal (20 = 0.20)

for the coat:

225-(225x0.20)

225-40 = 180

for the boots:

130- (130x0.20)

130-26 = 104

The doubling time of the hourly wage of the workers is an illustration of an exponential function that has a rate of 2

The doubling time of the wage is 4 years

A doubling function is represented as:

[tex]p = w \times 2^{\frac{x}{t}}[/tex]

Where:

So, we have:

[tex]10.19 = 6.80 \times 2^{\frac{x}{7}}[/tex]

Divide both sides by 6.80

[tex]1.50 = 2^{\frac{x}{7}}[/tex]

Take the logarithm of both sides

[tex]\log(1.50) = \log(2^{\frac{x}{7}})[/tex]

Apply the law of logarithm

[tex]\log(1.50) = \frac{x}{7}}\log(2)[/tex]

Multiply both sides by 7

[tex]7 \times \log(1.50) = x\log(2)[/tex]

Divide both sides by log(2)

[tex]x = 7 \times \log(1.50) \div \log(2)[/tex]

[tex]x = 4.09[/tex]

Approximate

[tex]x \approx 4[/tex]

Hence, the doubling time is 4 years

The path difference if the distance between slits on a diffraction grating is 0.60 mm, and one of the angles of diffraction is 0.30° is 1.57 × 10⁻⁶ m.

When the maxima of two waves add up (the two waves are in phase), the amplitude of the resultant wave equals the total of the separate amplitudes, this is known as constructive interference.

We know that for constructive interference, therefore, the formation of bright fringe through a diffraction grating is given by:

d sin θ = n λ

where d is the distance between slits, θ is the angle of diffraction, n is the order of fringe, and λ is the path difference.

As it is given that the distance between slits on a diffraction grating is 0.60 mm, and one of the angles of diffraction is 0.30°, therefore, the path difference can be written as,

[tex]\begin{aligned}\lambda &= \dfrac{(d sin \theta)}{ n} \\\\&=\dfrac{0.60 \times 10^{-3 }m) \times sin (0.30)}{2}\\\\ &= 1.57 \times 10^{-6}\rm\ m\end{aligned}[/tex]

Hence, the path difference is 1.57 × 10⁻⁶ m.

Answer:

Approximate population ≈ 74.36 million.  

Step-by-step explanation:

The given problem involves modeling of an exponential growth or decay function of a population.      

We can model the exponential growth of a population using the following Exponential Growth Model:

Where:

Based from the given equation, [tex]\displaystyle\mathsf{y\:=\:58.7(1.03)^t }[/tex] , we can infer that:

⇒   [tex]\displaystyle\mathsf{P(t)\:=\:P_0 (1\:+\:r)^t }[/tex] or  [tex]\displaystyle\mathsf{y\:=\:P_0 (1\:+\:r)^t }[/tex]

Where:

Step 1: Substitute the given values into the Exponential Growth Model formula, and solve for P( t ) :

[tex]\displaystyle\mathsf{P(t)\:=\:P_0 (1\:+\:r)^t }[/tex]

⇒   [tex]\displaystyle\mathsf{P(8)\:=\:58.7 (1\:+\:.03)^8 }[/tex]

Step 2: Follow the order of operations, addition inside the parenthesis:

⇒   [tex]\displaystyle\mathsf{P(8)\:=\:58.7 (1.03)^8 }[/tex]

Step 3: Follow the order of operations, applying the exponent into the parenthesis (do not round off the digits inside the parenthesis):

⇒  [tex]\displaystyle\mathsf{P(8)\:=\:58.7 (1.266770081) }[/tex]  

Step 4: Follow the order of operations, multiplying  58.7 (P₀) into the parenthesis:

⇒  [tex]\displaystyle\mathsf{P(8)\:\approx \:74.35940378\quad or \quad 74.36\:\:million}[/tex]

Therefore, the approximate population of the country in January 2002 is 74.36 million.

The sum of all the probabilities must be one. Then the probability that the gymnast scores a 9 or 9.95 is 0.14.

It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.

Researching on the internet, the probability of the gymnast getting each score is given by:

Considering that it is a distribution, the sum of all the probabilities must be one.

0.02 + 0.02 + 0.06 + 0.1 + 0.16 + 0.14 + 0.18 + 0.18 + x + 0.02 = 1

0.88 + x = 1

           x = 0.12

The probability that the gymnast scores a 9 or 9.95 will be

P(9 or 9.5) = (X = 9) + P(X = 9.5) = 0.12 + 0.02 = 0.14
