Answer 2

The height of the air balloon is 63.4 yards.

What is a trignometry?

Trigonometry is a branch of mathematics that uses variables to determine heights and distances. It is the study of the properties of right angled triangles and trigonometric functions and of their applications.

For the given situation,

The diagram below shows the situation described above.

The distance between Caleb and Emily = 100 yards

Let the distance from Caleb to the air balloon be 'x'

Let the distance from Emily to the air balloon be 'y'

Let height of the air balloon be 'h'

⇒ [tex]x+y=100[/tex]

⇒ [tex]x=100-y[/tex]

We know that, [tex]tan[/tex] θ = [tex]\frac{perpendicular }{base}[/tex]

Now consider the triangle with angle 45°,

[tex]tan 45[/tex]° = [tex]\frac{h}{x}[/tex]

We know that tan 45° = 1 and substitute x = 100-y,

⇒ [tex]1 = \frac{h}{100-y}[/tex]

⇒ [tex]h=100-y[/tex]

This is equation 1.

Now consider the triangle with angle 60°,

[tex]tan60[/tex]° = [tex]\frac{h}{y}[/tex]

We know that, tan 60° = √3

⇒ [tex]\sqrt{3} = \frac{h}{y}\\[/tex]

⇒ [tex]h=y\sqrt{3}[/tex]

This is the equation 2.

On equating equation 1 and 2,

⇒ [tex]100-y=y\sqrt{3}[/tex]

⇒ [tex]y+y\sqrt{3}=100[/tex]

⇒ [tex]y(\sqrt{3}+1 )=100[/tex]

⇒ [tex]y=\frac{100}{\sqrt{3}+1 }[/tex]

Thus height, [tex]h=y\sqrt{3}[/tex]

Substitute the value of y in h,

⇒ [tex]h=\sqrt{3}(\frac{100}{\sqrt{3} +1} )[/tex]

⇒ [tex]h=\frac{100\sqrt{3} }{\sqrt{3}+1 }[/tex]

⇒ [tex]h=\frac{173.205}{2.732}[/tex]

⇒ [tex]h=63.397[/tex]

⇒ [tex]h=63.4[/tex]

Hence we can conclude that the height of the air balloon is 63.4 yards.

I really need explanation for this Mean Value Theorem. Thanks

Answers

[tex]\bf f(x)= \begin{cases} 4,&x=0\\ ax+b,&0\ \textless \ x\le 1\\ x^2+5x+c,&1\ \textless \ x\le 2 \end{cases}[/tex]

the mean value theorem states, that the function for such value to exist, must be continuous and differentiable, graph wise, that means the graph of the function between those bounds, must be "a smooth line", without any abrupt jumps or changes like a spike or a sharp sink.

so, rewording the material some, the piece-wise function has 3 subfunctions, and within the interval of [0, 2], those 3 must meet seamlessly at the junction points, namely 0 and 1, so the "4" part must seamlessly blend in with the ax + b part at 0, and the ax + b part must meet seamlessly with the x²+5x+c.

that said, we could simply freely pick a "c" value for the third subfunction, and from there, make the second subfunction to meet it at that point, so let's do so.

let's say, we pick c = 3, so the 3rd subfunction is x² + 5x + 3.

now, what's f(x) for that parabola at x = 1?, well, is 1²+5(1)+3, or 9, so it lands on the ( 1, 9 ) point then.

now, the "4" subfunction is just a horizontal line, well, at x = 0, is really just a dot, so, ax + b must meet that dot and also must meet the parabola at (1, 9), given that c = 3.

so, now, what's the equation of a line that passes through (0, 4) and (1, 9)?

[tex]\bf \begin{array}{lllll} &x_1&y_1&x_2&y_2\\ % (a,b) &({{ 0}}\quad ,&{{ 4}})\quad % (c,d) &({{ 1}}\quad ,&{{ 9}}) \end{array} \\\\\\ % slope = m slope = {{ m}}= \cfrac{rise}{run} \implies \cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{9-4}{1-0}\implies 5 \\\\\\ % point-slope intercept \stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-4=5(x-0)\implies \boxed{y=5x+4}[/tex]

so, that'd be the 2nd subfunction, meeting "4" and x² + 5x + 3, and surely you can see what "a" and "b" are.

check the picture below.

and since they meet seamlessly, they meet the mean value theorem at  [0, 2].

900 - 250 = 650

650 / 250 = 13 / 3 = 2.6 = 260%

Answer:

260 %

Step-by-step explanation:

1) Since, the percentage formula is,

[tex]\text{Percent Increase}=\frac{\text{Amount of Increase}}{\text{Original Amount}}[/tex]

2) Given,

Original amount = 250,

New amount = 900

So, the amount of increase = New amount - Original amount = 900 - 250 = 650

By substituting the values,

[tex]\text{Percentage increase}=\frac{650}{250}[/tex]

3) Now, for expressing the ratio into percentage we need to multiply by 100,

Find the probability of getting exactly 6 girls in 8 births.

Answers

The probability of having exactly [tex]6[/tex] girls in [tex]8[/tex] birth is [tex]\boxed{\bf 0.10937}[/tex].

Further explanation:

Concept used:

The probability of an event [tex]E[/tex] is calculated as follows:

[tex]\boxed{P(E)=\dfrac{n(E)}{n(S)}}[/tex]  

Here, [tex]n(E)[/tex] is the number of favorable outcomes in an event [tex]E[/tex] and [tex]n(S)[/tex] is the number of element in sample space [tex]S[/tex].

The probability of exactly [tex]r[/tex] success in [tex]n[/tex] trial is expressed as follows:

[tex]\boxed{P(F)=^{n}C_{r}p^{r}q^{n-r}}[/tex]

Here, [tex]r[/tex] is the probability of success in an event and [tex]q[/tex] is the probability of failure.

Calculation:

Consider [tex]A[/tex] as an event of having a girl in first birth and [tex]P(A)[/tex] as the probability of event [tex]A[/tex].

The probability of having a girl is [tex]P(A)=\frac{1}{2}[/tex].

Assume that [tex]A'[/tex] is the complement event of an event [tex]A[/tex] and [tex]P(A')[/tex] is the probability of complementary event [tex]A'[/tex].

The event is the event of not having a girl in the first birth.

The probability of event [tex]A'[/tex] is calculated as follows:

[tex]\boxed{P(A')=1-P(A)}[/tex]   …… (1)

Substitute [tex]P(A)=\frac{1}{2}[/tex] in the equation (1) to obtain the probability of event [tex]A'[/tex].

[tex]\begin{aligned}P(A')&=1-\dfrac{1}{2}\\&=\dfrac{1}{2}\end{aligned}[/tex]

 

The probability of having exactly [tex]6[/tex] girls in [tex]8[/tex] birth is calculated as follows:

[tex]\begin{aligned}P(F&)=^{8}C_{6}\left(\dfrac{1}{2}\right)^{6}\left(\dfrac{1}{2}\right)^{8-6}\\&=\dfrac{8!}{6!\cdot 2!}\cdot (0.5)^{6}\cdot (0.5)^{2}\\&=28(0.5)^{8}\\&=0.10937\end{aligned}[/tex]  

Thus, the probability of having exactly [tex]6[/tex] girls in [tex]8[/tex] birth is [tex]\boxed{\bf 0.10937}[/tex].

Final answer:

To find the probability of getting exactly 6 girls in 8 births, we use the binomial probability formula. In this case, the probability is approximately 0.01.

Explanation:

To find the probability of getting exactly 6 girls in 8 births, we can use the binomial probability formula:

P(x = 6) = C(n, x) * pˣ * (1-p)(n-x)

Where:

C(n, x) is the binomial coefficient, which represents the number of ways to choose x objects from a set of n objects.p is the probability of success (in this case, the probability of having a girl) in a single trial. n is the number of trials (in this case, the number of births).x is the desired number of successes (in this case, the desired number of girls).

In this particular case, P(x = 6) = C(8, 6) * (0.5)⁶ * (0.5)(8-6) = 28 * 0.015625 * 0.015625 = 0.009765625, or approximately 0.01.

If ying zyiyu covered the first 200 miles of a trip going at 50 mph and the last hundred miles going at 40 mph, what was his average speed for the entire trip? Teacher told me it is not 45

Answers

Average speed is (total distance)/(total time).
To find the total time we need to do some division.
Time for 200 miles=200/50=4 hours.
Time for 100=100/40=5/2 hours.
Total time=13/2 hours. Total distance=200+100=300 miles.
Av speed=300/(13/2)=300×2/13=600/13=46.15 mph approx.

The average speed of ying zyiyu is [tex]46.15\;\rm{mph}[/tex]

Average speed is the ratio of the total distance traveled by a body to the total time taken by the body to cover the total distance.

Here, ying zyiyu covered the first [tex]200\;\rm miles[/tex] of the trip at [tex]50\;\rm mph[/tex] so,

Total time taken by ying zyiyu to cover [tex]200\;\rm miles[/tex] is calculated as-

[tex]t_1=\dfrac{200}{50}\\t_1=4\;\rm hour[/tex]

Similarly, ying zyiyu covered the first [tex]100\;\rm miles[/tex] of the trip at [tex]40\;\rm mph[/tex] so,

Total time taken by ying zyiyu to cover [tex]100\;\rm miles[/tex] is calculated as-

[tex]t_2=\dfrac{100}{40}\\t_2=2.5\;\rm hour[/tex]

So, the total time taken by ying zyiyu to travel [tex]300\;\rm miles[/tex] is [tex]4+2.5=6.5\;\rm hours[/tex]

Now, the average spped is calculated as-

[tex]\rm{Average\;Speed}=\dfrac{Total\;Distance}{Total\;Time}\\\rm{Average\;Speed}=\dfrac{300}{6.5}\\\rm{Average\;Speed}=46.15\;\rm mph[/tex]

b = The y-intercept.

We will find slope of our given line using the coordinates of our given points (6,2) and (8,6).

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{6-2}{8-6}[/tex]

[tex]m=\frac{4}{2}[/tex]

[tex]m=2[/tex]

Now, we will substitute [tex]m=2[/tex] and coordinates of point (8,6) in slope-intercept form of equation.

[tex]6=2*8+b[/tex]

[tex]6=16+b[/tex]

[tex]6-16=16-16+b[/tex]

[tex]-10=b[/tex]

Since y-intercept of our given line is [tex]-10[/tex], which is at [tex]x=0[/tex], therefore, option B is the correct choice.

You make $0.75 for every newspaper you sell. How many newspapers do you have to sell to buy soccer cleats? (soccer cleats are $36.00)

Write an equation then solve

Answers

Okay here's the equation:
0.75x = 36.00

x is the amount of newspapers you sell. We put it as x because we dont know how much we need to sell to buy soccer cleats, which are $36.00. To solve, we will use inverse operations:
0.75x = 36.00    
0.75x / 0.75 = 36.00 / 0.75
x = 48
You will have to sell 48 newspapers to get the soccer cleats.

Joaquin has $1,300 in the bank and has investments worth $4,000. He also has $7,000 worth of credit card debt. What is Joaquin's net worth? Select the best answer from the choices provided. $1,300 -$7,000 $5,300 -$1,700

Answers

The answer to this question would be: -$1,700

In this question, we can separate the account into positive/debit and negative/credit value. The positive/debit value should be:

Joaquin has $1,300 in the bank
He has $4,000 worth of investment
Total positive value = $1300 + $4000= $5300

The negative value should be 
$7,000 worth of credit card debt
Total positive value =$7000

Then the net worth should be: $5300 - $7000= -$1700

The Soup Shack usually makes tomato soup with 9 tomatoes for every 12 cups of soup. Today, they made 8 cups of soup with 6 tomatoes. How does today's soup compare to the usual recipe?

Answers

Answer:  We compare today's soup to the usual recipe by using "Unitary Method".

Step-by-step explanation:

Since we have given that

The Soup Shack makes tomato soup with 9 tomatoes for every 12 cups of soup.

For every 12 cups of soup , 9 tomatoes is needed

For every 1 cup of soup , the number of tomato is needed is given by

[tex]\frac{9}{12}=\frac{3}{4}[/tex]

Today, they made 8 cups of soup with 6 tomatoes ,

For 8 cups, 6 tomatoes are used .

For 1 cup, number of tomato is used is given by

[tex]\frac{6}{8}=\frac{3}{4}[/tex]

So, we can see that both the soup has same quantity .

∴ We compare today's soup to the usual recipe by using "Unitary Method".
