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°

At this price, i would say the demand is: Unitary Inelastic Elastic Based on this, to increase revenue we should: Lower Prices Raise Prices Keep Prices

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

The value of the investment at the end of 5 years be $ 15,281.012.

Given, 10400 dollars are invested at an interest rate of 8%.

We have to find the value of the investment at the end of 5 years.

Now, on using the compound interest formula, we get

Amount = P(1 + r/100)^t

Amount = 10400(1 + 8/100)^5

Amount = 10400(1.08)^5

Amount = 10400(1.469)

Amount = 15,281.012

Hence, the value of the investment at the end of 5 years be $ 15,281.012.

The number of ladies in the club = 18

and the number of gentlemen in the club = 2

Let x be the number of gentlemen.

So, the number of ladies would be 3x + 12

Total number of people in garden = x + (3x + 12)

                                                         = 4x + 12

In a garden club, 90% is ladies.

This means, (3x + 12) is 90 percent of (4x + 12)

We get an equation,

(3x + 12) = 90/100 * (4x + 12)

We solve above equation to find the value of x.

30x + 120 = 36x + 108

6x = 12

x = 2 (number of gentlemen)

So, the number of lades would be:

3x + 12 = 3(2) + 12

            = 18

Therefore, the number of ladies in the club = 18 and the number of gentlemen in the club = 2

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.

Answer:

y = - 3x - 14

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = - 3 , then

y = - 3x + c ← is the partial equation

to find c substitute (- 4, - 2 ) into the partial equation

- 2 = 12 + c ⇒ c = - 2 - 12 = - 14

y = - 3x - 14 ← equation of line

The derivative function f' for the function f is f'(x) = -10 / (5x+3)^2 and Equation of the line tangent to the graph of f  is 5x+2y+7=0.

Given function:

f(x) = 2/5x+3

a.

f'(x) = d/dx(2/5x+3)

According to power rules:

1/u = -1/u^2

= 2(1/(5x+3)^2) d/dx(5x+3)

= 2*5 / (5x+3)^2

= -10/(5x+3)^2

Hence derivative function f' for the function f is f'(x) = -10 / (5x+3)^2.

b.

(a,f(a)) and a = -1

f(-1) = 2/5(-1)+3

= 2/-5+3

= 2/-2

= -1

point (-1,-1)

slope f'(x) = -10/(5x+3)^2

f'(-1) = -10/(5(-1)+3)^2

= -10/(-2)^2

= -10/4

m = -5/2

Equation of the line is  y - y1 = m(x-x1)

y - (-1) = -5/2(x-(-1)

2(y + 1) = -5x - 5

5x + 2y + 2 + 5 = 0

Answer:

The Question is not Correct but answer is f 3 and g 3

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).

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

h = 359.12 feet

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.
