The equation of the directrix to the right of the center is equal to 2.8.

Given the following data:

(x - 1)²/9 - (y - 2)²/16 = 1.

Mathematically, the standard equation of the directrix lines for a hyperbola of the form (x - h)²/a² - (y - k)²/b² = 1 is given by:

x = h ± a²/√(a² + b²)

Where:

Substituting the given parameters into the standard equation, we have;

x = 1 ± a²/√(a² + b²)

x = 1 ± 9/√(9 + 16)

x = 1 ± 9/√25

x = 1 ± 9/5

x = 1 + 9/5

x = 1 + 1.8

x = 2.8.

The total number of grams of the supplement in one capsule will be 0.45 grams.

The measurement of any quanity is expressed by its unit. Now the units for the same matter can be expressed in different ways for higher quanity or lower quanity so we need to convert the units for the calculations.

Here in the question

Each capsule has 450 miligrams of supplement.

Total grams in one capsule will be calculated by unit conversion

[tex]\rm 1 \ gram=1000\ miligram\\\\\\1 \ Mg=\dfrac{1}{1000}\ gram\\\\\\450\ Mg=\dfrac{450}{1000}\ gram\\\\\\450 Mg=0.45\ gram[/tex]

Based on the calculations, the number of Jamal's triangle that are obtuse are: C. 3.

In order to determine an obtuse triangle, we would apply Pythagorean theorem:

c² = a² + b²

Where:

For an obtuse triangle, the square of the hypotenuse is greater than the sum of the square of both the adjacent and opposite side:

c² > a² + b²

For Triangle 1, we have:

7² > 6² + 3²

49 > 36 + 9

49 > 45 (obtuse triangle).

For Triangle 2, we have:

8² > 6² + 3²

64 > 36 + 9

64 > 45 (obtuse triangle).

For Triangle 3, we have:

8² > 7² + 3²

64 > 49 + 9

64 > 58 (obtuse triangle).

For Triangle 4, we have:

8² > 6² + 7²

64 > 36 + 49

64 < 85 (not obtuse triangle).

The number of students in the survey said that math was their favorite subject is given by: Option D: 123

Conditional relative frequency is relative frequency conditional to some special characteristic.

For this case, we're specified the following table:

[tex]\begin{array}{cccc}&\text{Math}&\text{Other favorite subject}&\rm Total\\\text{Male}&0.35&0.65&1.0\\\text{Female}&0.45&0.55&1.0\\\rm Total &0.41&0.59&1.0 \end{array}[/tex]

It is given that:

We have to find how many students in the survey said that math was their favorite subject.

From males, 0.35 out of 1 male said math was their favorite subject. (since total in male is 1, showing that the row of males got conditional relative frequency conditional to the gender male, and relative to the total count of males).

Thus, as out of 1, there was 0.35 supporter of math (from males), so from 120 male students, there were [tex]120\times 0.35 = 42[/tex] male students who had chosen math as their favorite subject.

Similarly, 0.45 per 1 female student chose their favorite subject as math.

Since there are 180 female students, therefore, total [tex]180\times 0.45 = 81[/tex] female students had chosen math as their favorite subject.

So, total 42+81=123 students had chosen math as their favorite subject.

Thus, the number of students in the survey said that math was their favorite subject is given by: Option D: 123

The equation of the value of the car over a year is 2357.14x + y = 33,000. Then the value of the car 4 years after it was purchased is $23571.43.

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

A new car is purchased for $33,000 and overtime its value depreciates by one half every 7 years.

Then the value of the car is given by the linear equation. Then the line is passing through (0, $33,000) and (7, $16,500). Then we have

Let y be the value of the car and x be the number of years. Then we have

[tex]\rm y \ - \ 33000 \ \ = -\dfrac{16,500}{7} (x-0)\\\\y+2357.14x = 33000[/tex]

Then the value of the car 4 years after it was purchased, to the nearest hundred dollars will be

[tex]\begin{aligned} \rm y +2,357.14 \times 4 &= 33,000\\\\\rm y + 9,428.57 &= 33,000\\\\\rm y &= 23,571.43 \end{aligned}[/tex]

Step-by-step explanation:

2820 = 2 * 2 * 3 * 5 * 47

Prime factors:

Largest prime factor:

47

Step-by-step explanation:

The largest prime factors of 2820 is 2*2*3*5*47 is the answer

The equation is  4^{3x} is equal to 8^{1/x} 2^{x+3} and the values of x are x is equal to (3+√69)/(10) or x is equal to (3-√69)/(10)

It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent [tex]\rm y = a^x[/tex]

where 'a' is a constant and a>1

After following the rules to model the equation.

The equation becomes:

[tex]\rm 4^3^x= 8^{1/x}\times 2^{x+3}[/tex]

After solving, we get:

[tex]2^{6x}= 2^{3/x \ +x+3}[/tex]  (power rule)

Taking log on both sides with base 2

[tex]\rm log_2(2^{6x})= log_2(2^{3/x \ +x+3})[/tex]

After solving, we will get a quadratic equation:

[tex]\rm 5x^2-3x-3 = 0[/tex]

After using quadratic formula, we will get,

[tex]\rm x=\dfrac{3+\sqrt{69}}{10}[/tex] or

[tex]\rm x=\dfrac{3-\sqrt{69}}{10}[/tex]

Thus, the equation is  4^{3x} is equal to 8^{1/x} 2^{x+3} and the values of x are x is equal to (3+√69)/(10) or x is equal to (3-√69)/(10)

Answer:

csc C  = 5/3 = 1. (6)

Step-by-step explanation:

Given:

∠B = 90° is a right angle

AB = 30

We know that:

sec A = 5/3 = 1/ cos A = 1/ ( adjacent side/hypothenuse) =

hypothenuse/ adjacent side to angle A

csc C = 1/ sin C = 1/ sinC = 1/ (opposite side /hypothenuse) =

hypothenuse/ opposite side to angle C

Note that :

adjacent side to angle A is the same as opposite side to angle C

Therefore sec A = csc C  = 5/3 ( fraction form) = 1.(6) (decimal form)
