Answer:

M<C = 37 degrees

M<D = 86 degrees

M<DEC = 111 degrees

Step-by-step explanation:

The exterior angle theorem can be measured by the hypotenuse of a 90 degree angle. Since there is no hypotenuse in the matrix, you don't need to make it positive :)

Therefore, after using this theorem, I came to the conclusion that m/C would be 37 degrees, since I calculated the measure of the angle. I used the same tactic on m/D and m/DEC.

I hope this helps :)

Decomposition of the fraction [tex]1\frac{3}{4}[/tex] =7/4 = 17/4 - 10/4

Here, the numerator, or top number, 7, indicates how many pieces we will examine.

Please look at figure a and pay attention to the three coloured components. The bottom number, our denominator, provides the total number of components. As a result, pay close attention to figure a. There are a total of four parts, numbered 1, 2, 3, and 4. However, since we are working with 7/4, we will just examine the three shaded parts.

7/4 = 17/4 - 10/4

7/4 = 11/4 - 4/4

Unit fraction decomposition will be used. Unit fraction - what is it? What would we focus on if we just looked at one element? It is one in four, or 1/4. Because this is the first of a series that includes 1, 2, 3, and 4. The third component would also be 1/4, and the second piece would be 1/4.

Answer:

s = 2 cm

Step-by-step explanation:

Given the following data;

Area of equilateral triangle = √3 cm

Mathematically, the area of an equilateral triangle is given by the formula;

A = √3 * s²/4

Where, s represents the sides of length.

Substituting into the formula, we have;

√3 = √3 * s²/4

Dividing both sides by √3, we have;

1 = s²/4

Cross-multiplying, we have;

4 = s²

Taking the square root of both sides, we have;

s = √4

s = 2 cm

The equation of the perpendicular line will be x + y - 5 = 0. Then the correct option is B.

Let the equation of the line be ax + by + c = 0. Then the equation of the perpendicular line that is perpendicular to the line ax + by + c = 0 is given as bx - ay + d = 0. If the slope of the line is m, then the slope of the perpendicular line will be negative 1/m.

The equation of the line passing through (-5, 6) and (-6, 5) will be given as,

(y - 6) = [(5 - 6) / (- 6 + 5)](x + 5)

y - 6 = (x + 5)

y = x + 1

The equation of the line that is perpendicular to the above line is given as,

y = - x + c

The equation of the line is passing through (3, 2)

3 = - 2 + c

c = 5

Then the equation of the perpendicular line will be given as,

y = -x + 5

The width of the two gardens will be equal to 5 feet.

A rectangle is a quadrilateral having four sides and the sum of the angles is 180 in the rectangle the opposite two sides are equal and parallel and the two sides are at 90-degree angles.

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.

Given that a rectangular garden has a length twice as great as it’s width. a second rectangular garden has the same width as the first garden and a length that is 4 meters greater than the length of the first garden. the second garden has an area of 70 square meters.

For the first rectangle, the  dimensions will be,

L = 2w

For second rectangle width is same then the area is,

L x w = 70

( 2w +4 ) x w = 70

2w² + 4w - 70 = 0

w² + 2w -35 = 0

w² + 7w - 5w -35 = 0

w(w + 7 ) -5(w+7) = 0

w =-7 and  w = 5

Hence, the width is w = 5 ft.

Step-by-step explanation:

First of all we find the total number of students:

4+6+2+2+3+4+6+3=30

Then we find the amount of seniors:

2+3=5

Now to find the probability we find the percentage of students which are seniors:

[tex]\frac{5}{30}[/tex] Which is also [tex]\frac{1}{6}[/tex] and when you put that into your calculator you get:

0.16666... which is a decimal, we need a percentage, so we multiply by 100 to convert it:

0.16666...×100=16.666...

which is equal to 17 once rounded as the third digit (6) rounds up

Answer:

To solve this problem, we can set up the following equation:

2L + 2W = 64

We are told that the length of the rectangle is two more than double the width, so we can write the following equation:

L = 2W + 2

Substituting this equation into the first equation, we get:

2(2W + 2) + 2W = 64

Simplifying this equation, we get:

6W + 4 = 64

Subtracting 4 from both sides, we get:

6W = 60

Dividing both sides by 6, we get:

W = 10

The width of the rectangle is 10 feet.

To find the length of the rectangle, we can substitute this value back into the equation L = 2W + 2 to get:

L = 2(10) + 2

= 20 + 2

= 22

The length of the rectangle is 22 feet.

Therefore, the dimensions of the rectangle are 10 feet by 22 feet.

(a) The next tide will occur at 6:55pm

(b) [tex]y = 3.12 \cos(\frac{24\pi}{149}(x - 6.5)) + 2.74[/tex]

(c) The height is: 2.904ft

Step-by-step explanation:

Given

[tex]T_1 = 12hr:25min[/tex] --- difference between high tides'

Solving (a): The next time a high tide will occur

From the question, we have that:

[tex]High =6:30am[/tex] --- The time a high tide occur

The next time it will occur is the sum of High and T1

i.e.

[tex]Next = High + T_1[/tex]

[tex]Next = 6:30am + 12hr : 25min[/tex]

Add the minutes

[tex]Next = 6:55am + 12hr[/tex]

Add the hours

[tex]Next = 6:55pm[/tex]

Solving (b): The sinusoidal function

Given

[tex]High\ Tide = 5.86[/tex]

[tex]Low\ Tide = -0.38[/tex]

[tex]T = 12hr:25min[/tex] -- difference between consecutive tides

[tex]Shift = 6.5hr[/tex]

The sinusoidal function is represented as:

[tex]y = A\cos(w(x - C)) + B[/tex]

Where

[tex]A = Amplitude[/tex]

[tex]A = \frac{1}{2}(High\ Tide - Low\ Tide)[/tex]

[tex]A = \frac{1}{2}(5.86 - -0.38)[/tex]

[tex]A = \frac{1}{2}(6.24)[/tex]

[tex]A = 3.12[/tex]

[tex]B = Mean[/tex]

[tex]B = \frac{1}{2}(High\ Tide + Low\ Tide)[/tex]

[tex]B = \frac{1}{2}(5.86 - 0.38)[/tex]

[tex]B = \frac{1}{2}(5.48)[/tex]

[tex]B = 2.74[/tex]

[tex]w = Period[/tex]

[tex]w = \frac{2\pi}{T}[/tex]

[tex]w = \frac{2\pi}{12:25}[/tex]

Convert to hours

[tex]w = \frac{2\pi}{12\frac{25}{60}}[/tex]

Simplify

[tex]w = \frac{2\pi}{12\frac{5}{12}}[/tex]

As improper fraction

[tex]w = \frac{2\pi}{\frac{149}{12}}[/tex]

Rewrite as:

[tex]w = \frac{2\pi*12}{149}[/tex]

[tex]w = \frac{24\pi}{149}[/tex]

[tex]C = shift[/tex]

[tex]C=6.5[/tex]

So, we have:

[tex]y = A\cos(w(x - C)) + B[/tex]

[tex]y = 3.12 \cos(\frac{24\pi}{149}(x - 6.5)) + 2.74[/tex]

Solving (c): The height at 3pm

At 3pm, the value of x is:

[tex]x=3:00pm - 6:30am[/tex]

[tex]x=9.5hrs[/tex]

So, we have:

[tex]y = 3.12 \cos(\frac{24\pi}{149}(x - 6.5)) + 2.74[/tex]

[tex]y = 3.12 \cos(\frac{24\pi}{149}(9.5 - 6.5)) + 2.74[/tex]

[tex]y = 3.12 \cos(\frac{24\pi}{149}(3)) + 2.74[/tex]

[tex]y = 3.12 \cos(\frac{72\pi}{149}) + 2.74[/tex]

[tex]y = 3.12 *0.0527 + 2.74[/tex]

[tex]y = 2.904ft[/tex]

Answer:

To graph an arithmetic sequence, you can start by plotting the first few terms of the sequence on the coordinate plane. The x-axis represents the term number, and the y-axis represents the value of the term.

In this case, we are given that the fourth term is 20 and the common difference is -1/5 times the first term. Let's say the first term is x. Then, the second term is x - (1/5)x = 4/5x, the third term is 4/5x - (1/5)x = 3/5x, and the fourth term is 3/5x - (1/5)x = 2/5x.

Therefore, the first four terms of the sequence are x, 4/5x, 3/5x, and 2/5x. If we plot these terms on the coordinate plane, we get the following graph:

(0, x)

(1, 4/5x)

(2, 3/5x)

(3, 2/5x)

This graph represents the first four terms of the arithmetic sequence. To find the fifth term, we can use the formula for the nth term of an arithmetic sequence: a_n = a_1 + (n - 1)d, where a_1 is the first term, d is the common difference, and n is the term number.

For this sequence, the fifth term is x + (-1/5)x = 4/5x. To find the sixth term, we can use the same formula: a_6 = x + (-1/5)x = 3/5x.

By continuing this process, we can plot the rest of the terms of the arithmetic sequence on the coordinate plane.

The area of the forest after 15 years will be 2189.4

The area is the region bounded by the shape of an object. The space covered by the figure or any two-dimensional geometric shape, in a plane, is the area of the shape.

i = The initial area of the forest = 4200km

r = Per year decrease is = 4.25%

n = Number of years = 15

The required formula is

The area of forest will be
