The Measures Of All Of The Interior Angles Of A Triangle Are In The Extended Ratio 1 : 2 : 3. The Value

Answers

Answer 1

Answer:

30 degrees

Explanation:

Let the ratio's be in x, 2x, 3x

Total Interior Angle of a triangle sum ups to 180°

x + 2x + 3x = 180°6x = 180°x = 180°/6 = 30°

The smallest angle which is x is 30°

Answers

The equation of the hyperbola with directrices at x = ±2 and foci at (5, 0) and (−5, 0) is [tex]\frac{x^2}{10} + \frac{y^2}{15} = 1[/tex]

How to determine the equation of the hyperbola?

The given parameters are:

Directrices at x = ±2 Foci at (5, 0) and (−5, 0)

The foci of a hyperbola are represented as:

Foci = (k ± c, h)

The center is:

Center = (h,k)

And the directrix is:

Directrix, x = h ± a²/c

By comparison, we have:

k ± c = ±5

h = 0

h ± a²/c = ±2

Substitute h = 0 in h ± a²/c = ±2

0 ± a²/c = ±2

This gives

a²/c = 2

Multiply both sides by c

a² = 2c

k ± c = ±5 means that:

k ± c = 0 ± 5

By comparison, we have:

k = 0 and c = 5

Substitute c = 5 in a² = 2c

a² = 2 * 5

a² = 10

Next, we calculate b using:

b² = c² - a²

This gives

b² = 5² - 10

Evaluate

b² = 15

The hyperbola is represented as:

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

So, we have:

[tex]\frac{(x - 0)^2}{10} + \frac{(y - 0)^2}{15} = 1[/tex]

Evaluate

[tex]\frac{x^2}{10} + \frac{y^2}{15} = 1[/tex]

Hence, the equation of the hyperbola is [tex]\frac{x^2}{10} + \frac{y^2}{15} = 1[/tex]

Answers

Answer:

[tex]x = 2, 4[/tex]

Step-by-step explanation:

Given :

[tex]\frac{4-x}{x^{2} -5x+4} + \frac{2}{x-1} =1[/tex]

=============================================================

Factorize the denominator of the first term :

⇒ x² - 5x + 4

⇒ x² - x - 4x + 4

⇒ x(x - 1) - 4(x - 1)

⇒ (x - 4)(x - 1)

============================================================

Hence, the equation now is :

[tex]\frac{4-x}{(x-1)(x-4)} + \frac{2}{x-1} =1[/tex]

============================================================

Multiply the second term by (x - 4) in the numerator and denominator :

[tex]\frac{4-x}{(x-1)(x-4)} + \frac{2(x-4)}{x-1(x-4)} =1[/tex]

============================================================

Combine the numerator of both terms and bring the denominator to the other side :

[tex]\frac{4-x+2(x-4)}{(x-1)(x-4)} = 1[/tex]

[tex]4 - x+2x-8 = x^{2} - 5x + 4[/tex]

[tex]x - 4 = x^{2} - 5x + 4[/tex]

[tex]x^{2} -5x-x+4+4=0[/tex]

what are the ways to determine if a relation is a function? select EACH correct answer

Answers

Answer:

the two selected are correct.

Step-by-step explanation:

A relation is a function only if it relates each element in its domain to only one element in the range. When you graph a function, a vertical line will intersect it at only one point. You can determine whether each element of the domain is paired with exactly one element of the range. For example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function. The best way to find out whether an equation represents a function or not is by graphing the equation and then applying the vertical line test. Graph the two-variable equation on graph paper. For a straight line this means graphing two or more points on the line and connecting the dots.

Suppose that y varies directly with x and inversely with z, hence the required expression will be:

If  y = 4 when x = 8 and z = 14 then;

4 = k(8)/14

8k = 56

k = 7

To  find z when x = 36 and y = 6, we  will have:

Answers

It will take approximately 5.5 years for the investment to be worth $23,000

Compound interest

From the question, we are to determine when the investments will worth $23,000

Using the compound interest formula,

[tex]A = P (1+\frac{r}{n})^{nt}[/tex]

Where A is the amount

P is the principal

r is rate

n is the number of times it is compounded

and t is the time in years

From the given information,

A = $23000

P =$18000

r = 6.7%

n = 4

t = ?

Putting the parameters into the formula, we get

[tex]23000 = 18000(1+\frac{6.7}{100 \times 4})^{4t}[/tex]

[tex]\frac{23000}{18000} = (1.01675)^{4t}[/tex]

PAINT TYPE COST(dollars per gallon) GALLONS(sq ft per gallon)
regular $35 200
metallic $100 80

The regular paint will require 2 coats, and the metallic paint will require 1 coat. Both paint types are sold only by the gallon. Based on the table, what is the least amount of money that should be budgeted to paint the monument?

Answers

The least amount of money that should be budgeted to paint the monument is $1692.

Least amount of money that should be budgeted

First step

Using Pythagorean theorem to find the surface area

Since POR is a right triangle

Hence:

PO=20

BR=12

OR=12

PR=√20²+12²

PR=400+144

PR=544

Area of PBC=1/2×24×√544

Area of PBC=12√544

Lateral surface area=4×12√544

Lateral surface area=48√544

Lateral surface area=1119.54²ft

Second step

Since regular paint is  2 coats 200 sq. ft per gallon

Hence:

Number of gallons=1119.54×2/200

Number of gallons= 11.2 gallons

11.2×35= 392

1119.54/80=13 gallons

13×100 =1300

Last step

Least amount=392+1300

Least amount= $1692

Therefore the least amount of money that should be budgeted to paint the monument is $1692.

Inaccuracy of the test = 1 - 97% = 3%

1.5% of the pigeons are infected. Thus;

1 - 1.5% = 98.5% pigeons are un-infected.

Inaccuracy of test is 1 - 99% = 1% .

Thus;

0.03 and 0.01 are the probability of an error being made in infected and un-infected respectively.

Meanwhile, probability of infected and un-infected are 0.015 and 0.985 respectively.
