The distance travelled before their first gas stop is 76.68 miles.

A fraction consisting of a quotient and remainder is a mixed fraction. we can convert the mixed fraction to improper fraction by first dividing the numerator by denominator and then taking the quotient as whole number and remainder as the numerator of proper fraction keeping the denominator same.

Consider that the distance covered before their first stop for gas be 'x'

The Total distance travelled is 372 miles

WE have given that after stopping for gas they travelled  65 1/4 miles and then tripled their distance. The equation is;

x + 261/4 + 3x = 372

4x + 261/4 = 372

16x + 261 = 1488

16x = 1227

x = 76.68 miles

The angle B is 66°

Given,

In the question:

If angle A is (2x) and angle B is (3x+11)°

and, the sum of angle A and angle B is 66°

To find the angle of B.

Now, According to the question:

Based on the given condition:

Angle A = 2x

Angle B = (3x + 11)°

The sum of angle A and B is 66°

2x +  (3x + 11)° =  66°

5x + 11 =  66°

Calculate the sum or difference

5x = 66 - 11

3x = 55

x = 55/3

The angle B is = 3x + 11

Plug the value of x in angle B

3 × 55/3 + 11

= 66

Hence, The angle B is 66°

Considering the situation described, it is found that:

At the null hypothesis, it is tested if the mean is of 6 minutes, that is:

[tex]H_0: \mu = 6[/tex]

At the alternative hypothesis, it is tested if the mean is less than 6, hence:

[tex]H_1: \mu < 6[/tex]

The test statistic is obtained as follows:

[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]

The parameters of the equation are:

Using a calculator from the sample, the values of the parameters are:

[tex]\overline{x} = 5.39, \mu = 6, s = 1.22, n = 15[/tex]

Hence the test statistic is:

[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{5.39 - 6}{\frac{1.22}{\sqrt{15}}}[/tex]

t = -1.94.

The p-value is obtained with a t-distribution calculator, with a left-tailed test, as we are testing if the mean is less than a value, with t = -1.94 and 15 - 1 = 14 df, hence it is of 0.0364.

Since the p-value is greater than the significance level of 0.01, the null hypothesis is not rejected and there is not enough evidence that the mean is less than 6 days.

The values of F1 and F2 are 77 and -22 degrees Fahrenheit respectively.

Given that; the equation F=9/5C+32 and ordered pairs are (25, F1), (−30, F2)

To convert the values to degrees Fahrenheit, we have to substitute the given values into the equation to get F1 and F2 respectively:

For (25, F1);

F = 9/5 C+32      

Now put C= 25 in the equation;

F1 = 9/5(25) + 32

F1 = 45 +22

F1 = 77 degrees Fahrenheit

For (−30, F2);

F = 9/5 C+32      

Now put C= -30 in the equation;

F2 = 9/5(-30) + 32

F2 = -54 + 32

F2 = -22 degrees Fahrenheit

Hence, the values of F1 and F2 are 77 and -22 degrees Fahrenheit respectively.

It would take 11.1 hours to decay from 500 grams to 299 grams.

We know that for an element with an half-life T has a decay equation that can be written as:

f(t) = A*e^(-t*ln(2)/T)

Where A is the initial amount, and f(t) is the amount of the element t hours after.

Here we know that:

A = 500g

T = 15h

Then the function is:

f(t) = 500g*e^(-t*ln(2)/15h)

And we want to find the value of t such that f(t) = 299g, then:

299g =  500g*e^(-t*ln(2)/15h)

299/500 = e^(-t*ln(2)/15h)

ln(299/500) = -t*ln(2)/15h

-ln(299/500)*15h/ln(2) = t

Answer:

Step-by-step explanation:

You want the steps to finding the equation of the hyperbola with center (1, 4), vertices (-7, 4) and (9, 4) and that includes the point (-11, -6).

The standard-form equation of a hyperbola with center (h, k) and semi-axes 'a' and 'b' is ...

  [tex]\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1[/tex]

The "linear eccentricity" 'c' is the distance from the center to a focus, and satisfies the equation ...

  c² = a² +b²

The vertices are (h±a, k) and the foci are (h±c, k).

The center of the hyperbola is given as (1, 4). The distance from the right vertex to the center is ...

  a = 9-1 = 8

The equation thus far is ...

  (x -1)/8² -(y -4)/b² = 1

The value of 'b' can be determined from the given point:

  (-11 -1)²/8² -(-6 -4)²/b² = 1

  9/4 -100/b² = 1

  5/4 = 100/b²

  b² = 100/(5/4) = 80

The linear eccentricity is ...

  c² = a² +b²

  c² = 64 +80 = 144

  c = √144 = 12

The foci are (1±12, 4) = (-11, 4) and (13, 4).

The equation is ...

  (x -1)²/64 -(y -4)²/80 = 1

Answer:

[tex]\dfrac{(x-1)^2}{64}-\dfrac{(y-4)^2}{80}=1[/tex]

Step-by-step explanation:

Standard equation of a horizontal hyperbola (opening left and right):

[tex]\boxed{\dfrac{(x-h)^2}{a^2}-\dfrac{(y-k)^2}{b^2}=1}[/tex]

where:

Given:

Therefore:

Find the value of a using the x-values of the vertices:

[tex]\begin{aligned}\implies h-a &= -7\\1-a &= -7\\a &= 8\end{aligned}[/tex]

[tex]\begin{aligned}\implies h+a &= 9\\1+a &= 9\\a &= 8\end{aligned}[/tex]

Therefore, a = 8.

Substitute the values of h, k and a into the formula:

[tex]\implies \dfrac{(x-1)^2}{8^2}-\dfrac{(y-4)^2}{b^2}=1[/tex]

[tex]\implies \dfrac{(x-1)^2}{64}-\dfrac{(y-4)^2}{b^2}=1[/tex]

Substitute the given point on the hyperbola (-11, -6) into the equation and solve for b²:

[tex]\implies \dfrac{(-11-1)^2}{64}-\dfrac{(-6-4)^2}{b^2}=1[/tex]

[tex]\implies \dfrac{(-12)^2}{64}-\dfrac{(-10)^2}{b^2}=1[/tex]

[tex]\implies \dfrac{144}{64}-\dfrac{100}{b^2}=1[/tex]

[tex]\implies \dfrac{144}{64}-1=\dfrac{100}{b^2}[/tex]

[tex]\implies \dfrac{144}{64}-\dfrac{64}{64}=\dfrac{100}{b^2}[/tex]

[tex]\implies \dfrac{80}{64}=\dfrac{100}{b^2}[/tex]

[tex]\implies \dfrac{5}{4}=\dfrac{100}{b^2}[/tex]

[tex]\implies b^2=\dfrac{4 \cdot 100}{5}[/tex]

[tex]\implies b^2=\dfrac{400}{5}[/tex]

[tex]\implies b^2=80[/tex]

Therefore, the equation of the hyperbola is:

[tex]\boxed{\dfrac{(x-1)^2}{64}-\dfrac{(y-4)^2}{80}=1}[/tex]

To find the foci, first find c where c² = a² + b²:

[tex]\implies c=\sqrt{a^2+b^2}[/tex]

[tex]\implies c=\sqrt{64+80}[/tex]

[tex]\implies c=\sqrt{144}[/tex]

[tex]\implies c=12[/tex]

Substitute the found value of c, along with the values of h and k into the foci formula:

[tex]\implies (h+c, k)=(1+12, 4)=(13,4)[/tex]

[tex]\implies (h-c,k)=(1-12,4)=(-11,4)[/tex]

Therefore, the foci are (-11, 4) and (13, 4).

Answer of the why did George Washington caution against the formation of political parties?

What potential risks do political parties pose towards democracy? Do you think that the country should have followed his advice are as follows :  

(a) He believes that the government was undermined by differences between the political parties. Additionally, he argues that "the alternate domination" of one party over another and concurrent attempts to exact revenge on their rivals have resulted in terrible atrocities and "is itself a frightful despotism."

(b)The democratic theory's main tenet is that democracies force administrations to take citizens' preferences into account. Every contemporary democracy is organized by political parties, and some observers contend that parties are what makes democracies responsive. Others, however, contend that parties give extremists a platform and make governments less receptive to the needs of the populace. As newly established democracies around the world grapple with concerns of representation and governability, the discussion of parties and democracy assumes fresh prominence.

The airplane is 359.12 feet high.

Given,

The distance between the observers = 1050 feet

When an aero plane crosses the line connecting them, each observer measures the plane's elevation angle.

Angle A = 40 degrees

Angle B = 30 degrees

We have to find the height of the airplane.

Here,

C = 180 - (40 + 30) = 110°

According to the sine rule :

Sin110 / 1050 = Sin40 / b = Sin 30 / a

1050 sin40 / sin 110 = b = 718.24 ft

1050 sin 30 / sin 110 = a = 558.69 ft

Sin 40 = h / 558.69

h = 558.69 × sin 40
