Answer:

a : c = 3 : 20

Step-by-step explanation:

Given ratios:

The value of b is 3 and 5.

The lowest common multiple of 3 and 5 is 15.

Multiply each ratio by a factor of 15 so that b is 15.

Multiply ratio a : b by 3:

⇒ a : b = 6 : 15

Multiply ratio b : c by 5:

⇒ b : c = 15 : 40

Therefore:

⇒ a : b : c = 6 : 15 : 40

So a : c is:

⇒ a : c = 6 : 40

Simplest form:

⇒ a : c = 3 : 20

1. The x - intercepts of the parabola are

2. The meaning of the x-intercepts are the plane takes of at x = 2.5 s and lands at x = 7.5 s

3. The vertex of the parabola is at (5, 80).

A parabola is a curved shape

1. Given the parabola above, to find the x - intercepts, we proceed as follows.

The x-intercepts are the points at which the graph cuts the x-axis.

They are

2. The meaning of the x-intercepts in this problem are the points where the plane takes off and lands on the ground.

The plane takes of at x = 2.5 s and lands at x = 7.5 s

3. The vertex is the maximum point on the graph.

So, we see that the vertex is at x = 5 s and y = 80 ft

So, the vertex is at (5, 80).

First, you need to note that the fertilization ratios of all the flowers occurred in the ratio of 3:1. This was a striking simiarity. The slight differences were because of the random nature of fertilization.

To identify the similarities, we first need to round the numbers off to the nearest whole number. This means that if the number after the decimal point is higher than 5, we could simply add 1 to the number before it. But if it is lesser, we can leave it the same.

All of the figures when rounded up have a ratio of 3;1. So, this is the similarity.

1.  Flower color: 705:224 = 3.15: 1.00 or 3:1

2. Seed color: 6022: 2001 = 3.01: 1.00 or 3:1

3. Seed shape: 5474:1850 = 2.95: 1.00 or 3: 1

4. Pod color: 428:152 = 2.815: 1.00 or 3: 1

5. Pod shape: 882:299 = 2.95: 1.00 or 3: 1

6. Flower position: 651:207 = 3.14: 1.00 or 3: 1

7. Plant height: 787:277 = 2.84: 1.00 or 3:1

The reason why all the ratios were not exactly the same was that they underwent fertilization which is a random phenomenon.

Step-by-step explanation:

5-(-4)=9

1-6=-5

Answer:

Step-by-step explanation:

Perimeter of a rectangle  =  52 cm

2(length + width)  =  52 ==>  l + w  =  26

Let x be the length

width  =  (x/3) + 2

x + (x/3) + 2  =  26

[(3x + x)/3]  + 2 =  26

4x / 3  =  24

4x  =  24 (3)

x  =  6(3) ==>  18 cm

Width  =  (18/3) + 2

=  6 + 2  =  8 cm

So, the required dimension is 18 cm x 8 cm.

Answer:b

Step-by-step explanation:

The right response is C. Sine (A) = Sine (B) = Sine (C) (C) where, trigonometry respectively, a, b, and c are the lengths of the triangle's sides that face angles A, B, and C.

Trigonometry is the branch of trigonometry that studies the relationship between trigonometry side lengths and angles. Due to the application of geometry in astronomical studies, the topic initially emerged in the Hellenistic era, about in the third century BC.

Certain trigonometric trigonometry and their potential applications in computations are covered by the branch of mathematics known as precise methods.

The right response is C.

Sine (A) = Sine (B) = Sine (C) (C)

where, respectively, a, b, and c are the lengths of the triangle's sides that face angles A, B, and C.

The rule of sines applies to all angles and sides of a triangle, whereas Option A only considers the ratio of one angle to one neighbouring side.

Option B is erroneous because the rule of sines applies to all triangle sides, however Option B only considers the ratio of one angle to the shortest side.

Option D is erroneous because the rule of sines applies to all triangle sides, however Option D only considers the ratio of one angle to the longest side.

Answer:

(-2,-3)

Step-by-step explanation:

Put the equations over each other.

\( \binom{x - y = 1}{ - x + 3y = - 7 } \)

Subtract the x values.

\( \binom{ - y = 1}{3y = - 7} \)

Subtract on both sides.

\(2y = - 6\)

Divide on both sides.

\(y = - 3\)

Insert the y value into one of the equations.

\(x - ( - 3) = 1\)

Get rid of the parenthesis.

\(x + 3 = 1\)

Subtract on both sides.

\(x = - 2\)

You could also individually plug in each solution into both equations to see if they are true.

1.57 meters of barbed wire are needed to fence the circular piece of land with a radius of 25 cm.

We have,

To calculate the amount of barbed wire needed to fence the circular piece of land, we need to find the circumference of the circle.

Given:

Radius (r) = 25 cm

The formula for the circumference (C) of a circle is:

C = 2πr

Substituting the given radius into the formula, we have:

C = 2π x 25 cm

Now, we can calculate the circumference in centimeters.

C = 2 x 3.14 x 25 cm

C ≈ 157 cm

Now,

To convert centimeters to meters, we divide the circumference by 100.

C (in meters) = 157 cm / 100

C (in meters) ≈ 1.57 meters

Therefore,

Approximately 1.57 meters of barbed wire are needed to fence the circular piece of land with a radius of 25 cm.

The exact values for sin(2x), cos(2x) and tan(2x) without solving for x  4√5 /9, -1/9 and -4√5  respectively

Given:  cos(x)= 2/3 and x is in quadrant IIn trigonometry, cos(x) = adjacent/hypotenuse = 2/3.

adjacent = 2

hypotenuse = 3

Here, we will find the opposite

opposite =√(3²-2²) = √5

sin(x) = (√5)/3   (opp./hyp.)cos(x) = 2/3    

(adj./hyp.)tan(x) = (√5)/2 (opp./adj.)

Using trigonometry identity:

sin(2x)  = 2sin(x)cos(x) sin(2x)  

= 2× (√5)/3 × 2/3sin(2x)  

=  4√5 /9cos(2x) = 2cos²(x) - 1

cos(2x) = 2(2/3)² -1cos(2x) = -1/9

Also, we will find the exact value for tan.

tan(2x) = 2tan(x) / 1-tan²(x)tan(2x) = (2(√5))/2 / 1-((√5)/2)²

tan(2x) = √5 / (-1/4)

tan(2x) = -4√5

Therefore, the exact values are given above.

Answer: C is the correct answer!I don't feel like explaining. sorry.Please let me know if I am wrong.

The solution to the nonlinear system of equations is (x, y) = (-3, -2) and (x, y) = (1, 6). These points represent the coordinates where the two equations intersect and satisfy both equations simultaneously.

To solve the nonlinear system of equations:

Equation 1: \(y = -x^2 + 7\)

Equation 2: y = 2x + 4

We can equate the right sides of both equations since they both represent y.

\(-x^2 + 7 = 2x + 4\)

To simplify the equation, we can rearrange it to be in the standard quadratic form:

\(x^2 + 2x - 3 = 0\)

Now, we can solve this quadratic equation by factoring, completing the square, or using the quadratic formula. In this case, let's use factoring:

(x + 3)(x - 1) = 0

From this equation, we get two possible solutions:

x + 3 = 0 => x = -3

x - 1 = 0 => x = 1

Now, we substitute these x-values back into either equation to find the corresponding y-values.

For x = -3:

y = 2(-3) + 4

y = -6 + 4

y = -2

For x = 1:

y = 2(1) + 4

y = 2 + 4

y = 6

The mean and standard deviation for the set of data is 35.25 and 5.9.

To find the mean, we add up all the numbers in the set and divide by the total number of numbers:

Mean = (17 + 14 + 26 + 18 + 11 + 20 + 22 + 17 + 29 + 16 + 12 + 15) / 12

Mean = 20

To find the standard deviation, we need to first find the variance.

The variance is the average of the squared differences from the mean:

Variance = [\((17 - 20)^2\) +\((14 - 20)^2\) + \((26 - 20)^2\) + \((18 - 20)^2\) + \((11 - 20)^2\) + \((20 - 20)^2\) + \((22 - 20)^2\) + \((17 - 20)^2\) + \((29 - 20)^2\) + \((16 - 20)^2\) + \((12 - 20)^2\) + \((15 - 20)^2\)] / 12

Variance = 35.25

The standard deviation is the square root of the variance:

Standard deviation = sqrt(35.25)

Standard deviation = 5.9 (rounded to the nearest tenth)

The correct statement regarding the transformation is given as follows:

Dilation bu a scale factor of 0.5 about the origin. Then reflect over the x-axis.

The true statements about the dilation are given as follows:

A dilation can be defined as a transformation that multiplies the distance between every point in an object and a fixed point, called the center of dilation, by a constant factor called the scale factor.

For this problem, the coordinates of the dilated line segment are half the coordinates of the original line segment, hence the scale factor is given as follows:

k = 0.5.

The y-coordinate then has the signal exchange, hence the figure is also reflected over the x-axis.
