option 1 is correct , trigonometric ratio to solve for the missing side is sine.

we have an angle of 54 degrees and a hypotenuse of 12 units. We can use trigonometric ratios to solve for the missing side, which is the perpendicular side.

In a right triangle, the three primary trigonometric ratios are:

Sine (sin): the ratio of the length of the side opposite the angle to the hypotenuse.

Cosine (cos): the ratio of the length of the side adjacent to the angle to the hypotenuse.

Tangent (tan): the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.

Given that we know the hypotenuse (12 units) and the angle (54 degrees), we can use the sine ratio to solve for the length of the perpendicular side. The sine ratio is defined as:

sin(x) = opposite/hypotenuse

Plugging in the given values:

sin(54 degrees) = opposite/12

To solve for the length of the perpendicular side (opposite), we can rearrange the equation:

opposite = sin(54 degrees) * 12

Using a calculator, we can find the value of sin(54 degrees) and multiply it by 12 to find the length of the perpendicular side.

Answer:

The formula for calculating the future value of an investment with compound interest is:

A = P(1 + r/n)^(nt)

where A is the future value, P is the principal (initial amount), r is the annual interest rate (as a decimal), n is the number of times the interest is compounded per year, and t is the time period in years.

In this case, P = $2500, r = 0.0125 (1.25% as a decimal), n = 12 (since the interest is compounded monthly), and t = 4.

Plugging these values into the formula, we get:

A = 2500(1 + 0.0125/12)^(12*4) ≈ $2,628.11

Therefore, the answer is $2628.11.

Answer: $ 2628.11

Step-by-step explanation:

Compound interest is nasty.

the formula (which you need to memorize) is:

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

A is the final amount, P is the principle, (original amount of money invested), r is the rate of return (as a decimal NOT percent), n is the number of times compounded annually, and t is the time, (in years), invested.

With all this information, our formula becomes:

[tex]A = 2500(1+\frac{0.0125}{12} )^4^8[/tex]

solving, we get A ≅ 2628.11

This corresponds to answer choice C

The perimeter of the rectangle is 72 cm.

Perimeter is the total distance around the boundary of a two-dimensional shape. It is the sum of the lengths of all sides or edges of the shape.

The perimeter is usually measured in units such as centimeters (cm), meters (m), feet (ft), or inches (in), depending on the unit of measurement used for the sides or edges.

Let's start by assigning variables to the length and width of the rectangle.

Let x be the width of the rectangle in cm.

Then, the length of the rectangle is double the width, which is 2x cm.

We know that the area of the rectangle is 288 cm², so we can set up an equation:

Area = Length x Width

288 = 2x * x

Simplifying the equation, we get:

288 = 2x²

Dividing both sides by 2, we get:

144 = x²

Taking the square root of both sides, we get:

x = ± 12

Since x cannot be negative (as it represents a length), we take x = 12 cm as the width of the rectangle.

The length of the rectangle is 2x, which is 24 cm.

Now we can find the perimeter of the rectangle, which is given by the formula:

Perimeter = 2(Length + Width)

Substituting the values we found, we get:

Perimeter = 2(24 + 12) = 72 cm

Therefore, the perimeter of the rectangle is 72 cm.

Knowing that t.05 = 1.812 when df = 10 helps us to determine the critical value of t for hypothesis testing in this scenario.

If we know that t.05 = 1.812 when df = 10, then it is correct to say that the critical value of t at the 5% significance level for a two-tailed test with 10 degrees of freedom is 1.812.

The t-distribution is a family of probability distributions that depend on the sample size and the degrees of freedom (df). The degrees of freedom represent the number of independent observations available to estimate the population parameters. In this case, when df = 10, the t-distribution has thicker tails compared to the standard normal distribution.

The value t.05 represents the critical value of t at the 5% significance level (or alpha level) in a two-tailed test. This means that if the calculated t-value falls outside the range of -t.05 to +t.05, then the null hypothesis can be rejected.

What is perimeter of triangle?

Finding the distance around a triangle entails determining its perimeter. The distance formula can be used to calculate the side lengths if you don't already know all of them. The simplest way to find a triangle's perimeter is to add up all of its sides' lengths.

The distance between two points (x1,y1) and (x2,y2) can be determined using the following formula: √(x₂-x₁)² + (y₂ - y₁)²

Let the given vertices are (-7, -2), (-2, -5) , and (2, 3).

Distance formula for two points is = √(x₂-x₁)² + (y₂ - y₁)²

Using the formula,

AB = √((-2)-(-7))² +((-5)-(-2))²

= √(-2+7)² + (-5+2)²

= √5² + (-3)²

= √25 + 9

= √31

Similarly, BC = √(2 - (-2))² + (3-(-5))²

= √(2+2)² + (3+5)²

= √4² + 8²

= √16+64

= √80

CA = √((-7)-2)² + (-2 + 3)²

Answer:

Step-by-step explanation:

To determine which function has the greatest y-intercept, we need to look at the constant term, which represents the y-intercept, of each function. The function with the largest constant term will have the greatest y-intercept.

For example, consider the following three functions:

1. f(x) = 2x + 5

2. g(x) = 3x - 7

3. h(x) = -4x + 10

The constant term for each function is 5, -7, and 10 respectively. Therefore, h(x) has the greatest y-intercept of 10, since its constant term is larger than those of f(x) and g(x).

The population N(t) at any time t≥0 is given by the function N(t) = 100t^2 + 800t + 1332.

a) To find the population after 14 days, we need to integrate the given rate function from 0 to 14:

N(14) - N(0) = ∫(0 to 14) N'(t) dt

N(14) - 1500 = ∫(0 to 14) [200(t+2) - 12] dt

N(14) - 1500 = [100[tex]t^2[/tex] + 800t - 168] evaluated from t=0 to t=14

N(14) = 1500 + [100(14[tex])^2[/tex] + 800(14) - 168] - [100(0[tex])^2[/tex] + 800(0) - 168]

N(14) = 1500 + 17,512

N(14) = 19,012

So the population after 14 days is 19,012 cells.

To find the population after 34 days, we can use the same method:

N(34) - N(0) = ∫(0 to 34) N'(t) dt

N(34) - 1500 = ∫(0 to 34) [200(t+2) - 12] dt

N(34) - 1500 = [100[tex]t^2[/tex] + 800t - 168] evaluated from t=0 to t=34

N(34) = 1500 + [100(34[tex])^2[/tex]+ 800(34) - 168] - [100(0[tex])^2[/tex] + 800(0) - 168]

N(34) = 1500 + 116,768

N(34) = 118,268

So the population after 34 days is 118,268 cells.

b) To find the population N(t) at any time t≥0, we can integrate the given rate function from 0 to t:

N(t) - N(0) = ∫(0 to t) N'(x) dx

N(t) - 1500 = ∫(0 to t) [200(x+2) - 12] dx

N(t) = 1500 + ∫(0 to t) [200(x+2) - 12] dx

N(t) = 1500 + [100[tex]x^2[/tex] + 800x - 168] evaluated from x=0 to x=t

N(t) = 1500 + 100[tex]t^2[/tex] + 800t - 168

N(t) = 100t^2 + 800t + 1332

To find out how many gallons of paint are needed to cover the walls, we need to first find the total area of the walls.

The four walls are rectangles with a length of 20 feet and a height of 12 feet. So, the area of one wall is:

20 feet x 12 feet = 240 square feet

Since there are four walls, the total area of the walls is:

4 x 240 square feet = 960 square feet

We know that one gallon of paint can cover approximately 320 square feet. To find how many gallons of paint are needed, we can divide the total area of the walls by the area covered by one gallon of paint:

960 square feet ÷ 320 square feet per gallon = 3 gallons of paint

Therefore, you need approximately 3 gallons of paint to cover the walls.

Game theory applies to “games” as varied as economics, politics, chess, and tic-tac-toe. In each case, there are some rules, some “players” or “agents”, and a set of strategies available to them.

Each player has a concept of “utility” – a “currency” they seek to individually maximize through the strategies they play.

The currency of evolution is the concept of fitness.

That is, the chance of being represented in the next generation. Genes and traits which increase the odds of survival to reproductive age are more likely to be passed on to future generations. Therefore, they confer a greater fitness to the individual which "hosts” them.

The evolutionary game theory takes the concepts from game theory and applies them in an evolutionary context.

In the hawk-dove game, at what value of c do doves and hawks have equal payoffs when hawks are extremely rare? The answer is that there is no such value. This is because when hawks are extremely rare, their payoff is higher than that of doves regardless of the value of c. Therefore, there is no point at which their payoffs will be equal.

Answer:

b

Step-by-step explanation:

The  probability that this particular fuel pump system  when put into the required condition would not remain functional  for the full 50 hours is 0.0199.

Therefore, the probability of a fuel pump failing in a mission can be evaluated using the formula designed for probability of failure in a system with two pumps in series connection

P(failure) = P(pump 1 fails) + P(pump 2 fails) - P(both pumps fail)

Here  
P(pump 1 fails) = P(pump 2 fails) = 0.01
P(both pumps fail) = (0.01)² = 0.0001.

Now,

P(failure) = 0.01 + 0.01 - 0.0001 = 0.0199

The  probability that this particular fuel pump system  when put into the required condition would not remain functional  for the full 50 hours is 0.0199.
