Answer:

a) The median AD from A to BC has a length of 6.

b) Areas of triangles ABD and ACD are the same.

Step-by-step explanation:

a) A median is a line that begin in a vertix and end at a midpoint of a side opposite to vertix. As first step the location of the point is determined:

[tex]D (x,y) = \left(\frac{x_{B}+x_{C}}{2},\frac{y_{B}+y_{C}}{2} \right)[/tex]

[tex]D(x,y) = \left(\frac{3 + 5}{2},\frac{-2 + 2}{2} \right)[/tex]

[tex]D(x,y) = (4,0)[/tex]

The length of the median AD is calculated by the Pythagorean Theorem:

[tex]AD = \sqrt{(x_{D}-x_{A})^{2}+ (y_{D}-y_{A})^{2}}[/tex]

[tex]AD = \sqrt{(4-4)^{2}+[0-(-6)]^{2}}[/tex]

[tex]AD = 6[/tex]

The median AD from A to BC has a length of 6.

b) In order to compare both areas, all lengths must be found with the help of Pythagorean Theorem:

[tex]AB = \sqrt{(x_{B}-x_{A})^{2}+ (y_{B}-y_{A})^{2}}[/tex]

[tex]AB = \sqrt{(3-4)^{2}+[-2-(-6)]^{2}}[/tex]

[tex]AB \approx 4.123[/tex]

[tex]AC = \sqrt{(x_{C}-x_{A})^{2}+ (y_{C}-y_{A})^{2}}[/tex]

[tex]AC = \sqrt{(5-4)^{2}+[2-(-6)]^{2}}[/tex]

[tex]AC \approx 4.123[/tex]

[tex]BC = \sqrt{(x_{C}-x_{B})^{2}+ (y_{C}-y_{B})^{2}}[/tex]

[tex]BC = \sqrt{(5-3)^{2}+[2-(-2)]^{2}}[/tex]

[tex]BC \approx 4.472[/tex]

[tex]BD = CD = \frac{1}{2}\cdot BC[/tex] (by the definition of median)

[tex]BD = CD = \frac{1}{2} \cdot (4.472)[/tex]

[tex]BD = CD = 2.236[/tex]

[tex]AD = 6[/tex]

The area of any triangle can be calculated in terms of their side length. Now, equations to determine the areas of triangles ABD and ACD are described below:

[tex]A_{ABD} = \sqrt{s_{ABD}\cdot (s_{ABD}-AB)\cdot (s_{ABD}-BD)\cdot (s_{ABD}-AD)}[/tex], where [tex]s_{ABD} = \frac{AB+BD+AD}{2}[/tex]

[tex]A_{ACD} = \sqrt{s_{ACD}\cdot (s_{ACD}-AC)\cdot (s_{ACD}-CD)\cdot (s_{ACD}-AD)}[/tex], where [tex]s_{ACD} = \frac{AC+CD+AD}{2}[/tex]

Finally,

[tex]s_{ABD} = \frac{4.123+2.236+6}{2}[/tex]

[tex]s_{ABD} = 6.180[/tex]

[tex]A_{ABD} = \sqrt{(6.180)\cdot (6.180-4.123)\cdot (6.180-2.236)\cdot (6.180-6)}[/tex]

[tex]A_{ABD} \approx 3.004[/tex]

[tex]s_{ACD} = \frac{4.123+2.236+6}{2}[/tex]

[tex]s_{ACD} = 6.180[/tex]

[tex]A_{ACD} = \sqrt{(6.180)\cdot (6.180-4.123)\cdot (6.180-2.236)\cdot (6.180-6)}[/tex]

[tex]A_{ACD} \approx 3.004[/tex]

Therefore, areas of triangles ABD and ACD are the same.

Answer:

Step-by-step explanation:

I don’t know the answer

The value of x such that ∠MNQ and ∠PNR are vertical angles is 40

The given parameters are:

MNQ = 3x - 6

PNR = 114

Vertical angles are equal.

So, we have:

3x - 6 = 114

Add 6 to both sides

3x = 120

Divide both sides by 3

Answer:

Amplitude = -3

Period = [tex]\frac{2\pi}{4}=\frac{\pi}{2}[/tex]

Frequency = [tex]\frac{1}{\pi/2}=\frac{2}{\pi}[/tex]

Vertical Shift = 6.

Step-by-step explanation:

Consider the function:

[tex]y=A\ sin (B(x+C))+D[/tex]

Here,

A = amplitude; It is the measure of how high is the peak from the center line.

2π/B = period; A period is the distance between one peak to the next.

C = phase shift; it represents how far the function is shifted horizontally from the initial point.

D = vertical shift; it represents how far the function is shifted vertically from the initial point.

The frequency of a function is the number of times something happens per unit time.

[tex]\text{Frequency}=\frac{1}{Period}[/tex]

The function provided is:

[tex]y=-3\ cos\ 4x+6[/tex]

On comparing the provided function with the general one it can be determined that:

Amplitude = -3

Period = [tex]\frac{2\pi}{4}=\frac{\pi}{2}[/tex]

Frequency = [tex]\frac{1}{\pi/2}=\frac{2}{\pi}[/tex]

Vertical Shift = 6.

[tex]T=\frac{1000-z}{63} \,\,\,\,or\,\,\,\,equivalently\,\,\,\,T=-\frac{1}{63} z+\frac{1000}{63}[/tex]

Step-by-step explanation:

If Maria has written already "z" words of her 1000 words essay, so the number of words she has left to do is "1000-z". Then the amount of time "T" that is left for her, is the quotient between 1000-z over 63 words/min (her writing rate).

We can then write that the time (T) it will take her to write the rest of the essay is:

[tex]T=\frac{1000-z}{63} \\T=-\frac{1}{63} z+\frac{1000}{63}[/tex]

Step-by-step explanation:

Graph shown in the attachment,

- Since every value of x corresponds to a distinct value of y, so the graph represents a function.

- Every input value of x of the table has a output value of y, therefore, it's a function.

- In the set of ordered pairs (5, 8) and (5, 2), input value x = 5 has two output values for y,

 y = 8 and y = 2

Therefore, it's not a function and (5, 8) should be changed to make the relation a function.

So one of the probability for one girl is 24/40 which is 3/5

The other probability of another girl is 23/39

So u multiply 23/39 by 3/5 which is 69/195

Correct me if this is wrong

Sorry

Answer:

30.77%.

Step-by-step explanation:

There are a total of 40 members.

24 girls 16 boys.

Prob( 0 girls being chosen - so all boys ) =  16/40 * 15/39*14/38*  13/37*12/36 = 0.0063956

Prob( first one to be chosen is a girl  then all boys) = (24/40*16/39*15/38*14/37*13/36) = 0.013276

There are 5 ways of 1 girl being chosen so

Prob(1 girl out of 5 chosen) = 0.013276 * 5 = 0.06638

Prob( First 2  chosen are girls then all boys) = 24/40 * 23/39 * 16/38*15/37*14/36

= 0.023489

Number of ways of 2 girls being chosen is 5C2 and so the probability of 2 girls

= 0.023489 * 5C2

= 0.023489 * 10

= 0.23489.

Required probability = 0.23489 + 0.06638 + 0.0063956.

= 0.3076656

= 30.77% to the nearest hundredth.

Answer:

It is wrong

Step-by-step explanation:

What we have is as follows;

9x + 2 = 8x^2 + 6x

Bringing 9x + 2 yo the right hand side, we have;

8x^2 + 6x -9x -2 = 0

8x^2 -3x -2 = 0

So what is used here is the quadratic formula and we want to try to see if it was used correctly.

The form we have in the question is however;

-8x^2+ 3x + 2 = 0

which is obtained by taking the right hand side of the equation to the left

Now;

using the quadratic formula;

x = -b ± √(b^2 -4ac)/2a

where a is -8

b = 3

c = 2

Thus we have

-3 ± √(9 - 4(-8)2)/2(-8)

-3 ± √(9 + 64)/(-16)

So where is wrong is in the square root

what we are supposed to have is 9 + 64 = 73 and not otherwise

Answer:

Step-by-step explanation:

No. The correct values of a, b, and c were substituted in, but the formula was simplified wrong. The 64 should be added so the radicand is 73. There should be 2 real roots.

Answer:

The situation per week is 30 + 6n

where n is the number of weeks

Range of the function is 18 for the first four weeks of data

Step-by-step explanation:

Here, we are to use an arithmetic sequence for a representation.

The first term here is a which is 30 clients while the common difference of d is 6 new clients per week

So we can write the nth term of the sequence as;

Tn = a + (n-1)d

Tn = 30 + (n-1)6

Tn = 30+ 6n -6

Tn = 24 + 6n

where n is the number of weeks

Now for the second week we shall have a total of a+ d clients = 30 + 6 = 36

For the third we have 24 + 6(3) = 24 + 18 = 42

For the fourth, we have 24 + 6(4) = 24 + 24 = 48

Thus the range mathematically means the difference between the highest and lowest for that four weeks = 48-30 = 18

Answer:

A lawn-mowing company is trying to grow its business. It had 18 clients when they started its business and wants to increase by 4 new clients each week.

Use an arithmetic sequence to write a function to represent this real-world situation and determine the range of the function for the first four weeks of data.

f(x) = 4x + 18; 0 ≤ y ≤ 4

Student Friendly Bank pays a simple interest rate of 2.5% per year. Neighborhood Bank pays a compound interest rate of 2.1% per year, compounded monthly.

Which bank will provide the largest balance if you plan to invest $10,000 for 10 years? For 20 years?

Answer:

-The bank that provides the largest balance if you plan to invest $10,000 for 10 years is Student Friendly Bank.

-The bank that provides the largest balance if you plan to invest $10,000 for 20 years is Neighborhood Bank.

Step-by-step explanation:

First, you have to calculate the balance if you invest the money in Student Friendly Bank. To do it, you have to use the simple interest formula to calculate the future value:

FV=PV(1+rt)

FV= future value

PV= present value

r= rate

t=time

-10 years:

FV= 10,000(1+(0.025*10))

FV= 10,000(1+0.25)

FV=10,000(1.25)

FV=12,500

-20 years:

FV= 10,000(1+(0.025*20))

FV= 10,000(1+0.5)

FV=10,000(1.5)

FV=15,000

Second, you have to calculate the balance if you invest the money in Student Neighborhood Bank. To do it, you have to use the compound interest formula to calculate the future value:

FV=PV(1+(r/m))^mt

FV= future value

PV= present value

r= rate

t=time

m=number compounding periods per year

-10 years:

FV=10,000*(1+(0.021/12))^12*10

FV=10,000*(1+0.00175)^120

FV=10,000*(1.00175)^120

FV=12,334.5

-20 years:

FV=10,000*(1+(0.021/12))^12*20

FV=10,000*(1+0.00175)^240

FV=10,000*(1.00175)^240

FV=15,214

According to this, the bank that provides the largest balance if you plan to invest $10,000 for 10 years is Student Friendly Bank because it will provide $12,500 and Neighborhood Bank will provide $12,334.5.

The bank that provides the largest balance if you plan to invest $10,000 for 20 years is Neighborhood Bank because it will provide $15,214 and Student Friendly Bank will provide $15,000.

To make k subject of the fomula :

Step 1 : cross multiply

Step 2 : Divide both side of the equation to isolate k

The solution of the expression for the value of k will be k = (mu² - 5mgk)/t.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

The given expression is t = (mu²)/k - 5mg. The value of the expression for the value of k will be,

The value of k will be written as,

t = (mu²)/k - 5mg

k = (mu² - 5mgk)/t

Therefore, the solution of the expression for the value of k will be k = (mu² - 5mgk)/t.
