Area k is a triangle with side lengths 117, 117, and 176.14. Let's find the area of the triangle. The diagram is shown below:

Now, we will find h, the height of the triangle using Pythagorean Theorem.

The area of the triangle (region K) is,

The area of region C is the area of trapezoid - area of region k (triangle). So, the area is >>>>

The equation of a straight line is

y = mx + c

4x + 20y = -180

make 20y the subject of the formula

20y = -180 - 4x

20y = -4x - 180

divide all through by 20

20y/20 = -4x/20 - 180/20

y = -1/5x - 9

The answer is y = -1/5x - 9 where your slope is -1/5 and intercept is -9

Differentiation - The value of g'(x) = [tex]\frac{1}{10}x^{-9}[/tex].

Apart from integration, differentiation is among the two key ideas in calculus. A technique for determining a function's derivative is differentiation. Mathematicians use a process called differentiation to determine a function's instantaneous rate of change predicated on one of its variables. The most typical illustration is velocity, which is the rate at which a distance changes in relation to time. Finding an antiderivative is the opposite of differentiation. The rate of change of signal with respect to y has been given by dy/dx if x and y are two variables. The general representation of a function's derivative is given by the equation f'(x) = dy/dx, where y = f(x) is any function.

Given that,

G(x) = [tex]\frac{1}{x^{10} }[/tex]

g’(x)=?

g’(x) is the derivative of g(x).

The derivative of [tex]x^{n} = nx^(n-1)[/tex]

[tex]x^{10} = 10x^(10-1)[/tex]

[tex]x^{10}= 10x^9[/tex]

Then,

[tex]\frac{1}{x^{10} }[/tex] = [tex]\frac{1}{10}x^{-9}[/tex]

Hence, The derivative of g(x) is [tex]\frac{1}{x^{10} }[/tex] = [tex]\frac{1}{10}x^{-9}[/tex].

Considering the normal distribution and the central limit theorem, it is found that:

a) The distribution is: x¯ ~ N(189, 1.91).

b) The probability that the average hand length is less than 191 is of 0.8531 = 85.31%.

c) The first quartile is of 187.7 mm.

d) The assumption is necessary, as the sample size is less than 30.

The z-score of a measure X of a variable that has mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by the rule presented as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The parameters in this problem are given as follows:

[tex]\mu = 189, \sigma = 7.4, n = 15, s = \frac{7.4}{\sqrt{15}} = 1.91[/tex]

Hence the sampling distribution of sample means is classified as follows:

x¯ ~ N(189, 1.91).

The probability that the average hand length is less than 191 is the p-value of Z when X = 191, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem:

[tex]Z = \frac{X - \mu}{s}[/tex]

Z = (191 - 189)/1.91

Z = 1.05

Z = 1.05 has a p-value of 0.8531, which is the probability.

The first quartile of the distribution is X when Z has a p-value of 0.25, so X when Z = -0.675, hence:

[tex]Z = \frac{X - \mu}{s}[/tex]

-0.675 = (X - 189)/1.91

X - 189 = -0.675 x 1.91

X = 187.7 mm.

We will call to the total of the brownies by 1. On this case, after Fred ate 1/3 of the brownies, he will have:

This means that he has left 2/3 of the brownies. After his family ate 1/6 of the brownies:

This means they will have left 1/2 of the tray of brownies, and that they ate half of it.

Given the situation to model the arithmetic and the geometric sequences.

Imagine you are four years old. A rich aunt wants to provide for your future. She has offered to do one of two things.

Option 1: She would give you $1000.50 a year until you are twenty-one.

This option represents the arithmetic sequence

The first term = a = 1000.50

The common difference = d = 1000.50

The general formula will be as follows:

Simplify the expression:

Option 2: She would give you $1 this year, $2 next year, and so on, doubling the amount each year until you were 21.

This option represents the geometric sequence

The first term = a = 1

The common ratio = r = 2/1 = 2

The general formula will be as follows:

Now, we will compare the options:

The first term of both options is when you are four years old that n = 1

you only received money for ten years so, n = 10

From the question the following can be derived:

(a)

Let x cans of juice and y cans of soda be purchased for the dorm. Then the cost of the juice and soda is 0.60x + 0.75y. The equation of all the combinations of juice and soda is 0.60x + 0.75y = 24.

(b)

The cost of exactly 24 cans of juice is $24 * 0.60 = $14.40. After this purchase, the remaining sum of money available is $24 - $14.40 = $9.60. This will suffice to buy 12 cans of soda, leaving a balance of $0.80. Thus. the entire money cannot be spent if exactly 24 cans of juice are purchased.

(c)

Below is a graph of the line 0.6x + 0.75y = 24 or 4x + 5y = 160 is plotted. All possible cimbinations of juice and soda will lie on this line. The x-intercept is 40 and the y-intercept is 32. Since neither of x and y can be negative, hence the lower and upper bounds for x are 0 and 40 and the lower ad upper bounds for y are 0 and 32. Also , x has to be multiple of 5 and y has to be a multiple of 4. As may be observed from the graph, only 9 combinations are possible which are (x, y):

(0, 32), (5, 28), (10, 24), (15, 20), (20, 16), (25, 12), (30, 8), (35, 4), (40, 0).

Step-by-step explanation:

We are given (a + 3) - (a + 2)

To think of this another way, we can distribute the negative sign out into the (a + 2)

(a + 3) -(a) - (2)

Now our expresssion looks like this:

(a + 3) - a - 2

Simplifying, we get

a - a + 3 - 2

The a terms cancel leaving us with

3-2

and that equals

1

Answer:

1

Step-by-step explanation:

1. Rewrite

         : (a+3)-(a+2) = a + 3 - a - 2

2. Subtract

         : 3-2 = 1 ... so now the equation is a + 1 - a

3. Combine like terms

         : a -a = 0 (the a's cancel out) ... now you're left with 1

Since there is nothing left, your answer is 1.

a) 84.13%

b) 2.28%

The domain and range of a linear function is always real numbers (T or F)

It is True. This is because of a couple of reasons.

    1.) You cannot divide by 0.

     2. A negative number cannot have its square root taken.

The range is determined by the domain in a linear function, and thus it must always consist of real numbers.

The midpoint m of z₁ = (9+7i) and Z₂ = (-7+7i) is 1 + 7i .

Given complex numbers:

[tex]z_{1}[/tex] = (9 + 7i) and [tex]z_{2}[/tex] = (-7 + 7i)

compare these numbers with a1+ib1 and a2+ib2, we get

a1 = 9, a2 = -7 , b1 = 7 and b2 = 7.

Mid point of complex numbers = a1 + a2 /2 + (b1 + b2 /2)i

= (9 + (-7)/2 + (7 + 7 /2)i

= 2/2 + 14/2 i

Mid point m = 1 + 7i

Therefore the midpoint m of z₁ = (9+7i) and Z₂ = (-7+7i) is 1 + 7i

By definition, Right triangles are those triangles that have an angle that measures 90 degrees.

The larger triangle is the triangle ABC, but you only know the lenght of the side BC, which is:

The y-intercept is the value of y when x = 0

To identify y-intercept on a graph, we will check for the the value of y when the line crosses the y axis

From the graph, the line crosses the y axis at y = 6

Hence, the y-intercept is 6

To get the slope, we will pick any two points on the line.

Using points (0, 6) and (4, 0)

Applying the slope formula:

NOTE: the slope is negative because it is going from up to down (moving downwards)

The equation of slope in intercept form: y = mx + b

m = slope = -3/2

b = y-intercept = 6

Answer

ŷ = -0.09x + 74.17

Explanation

For the given data set:

x 245 187 198 189 176 266 210 255

y 50 54 55 78 44 41 51 60

The sum of x = 245 + 187 + 198 + 189 + 176 + 266 + 210 + 255 = 1726

The sum of y = 50 + 54 + 55 + 78 + 44 + 41 + 51 + 60 = 433

Mean x = 1726/8 = 215.75

Mean y = 433/8 = 54.125

Sum of squares (SSx) = 8391.5

Sum of products (SP) = -779.75

(Check the table below of the data for a better understanding).

The regression Equation is given by ŷ = bX + a

b = SP/SSx = -779.75/8391.5 = -0.09292

a = My - bMx = 54.13 - (-0.09 x 215.75) = 74.17279

Therefore, the regression equation for the data set is: ŷ = -0.09292x + 74.17279

The correct answer is ŷ = -0.09x + 74.17

We have that 4 boys are competing and also 5 girls are competing. 3 medals are given to the boys and 3 medals are given to the girls.

For the boys, the gold medal can be awarded to one of 4 boys, then the silver medal can be awarded to 3 boys because 1 of them already got the gold medal. Finally, the bronze medal can be awarded to one of 2 boys, since the gold and silver medals are already taken. The number of ways the medals can be given to the boys is,
