Answer:

Part 1) [tex]sin(\theta)=-\frac{5\sqrt{61}}{61}[/tex]  or [tex]sin(\theta)=-\frac{5}{\sqrt{61}}[/tex]

Part 2) [tex]csc(\theta)=-\frac{\sqrt{61}}{5}[/tex]

Part 3) [tex]cot(\theta)=\frac{6}{5}[/tex]

Step-by-step explanation:

we know that

The point (-6,-5) lies on the III Quadrant

so

sin(theta) is negative

csc(theta) is negative

cot(theta) is positive

Part 1) Find the sine of angle theta

we know that

The function sine is equal to divide the opposite side to the angle theta by the hypotenuse

[tex]sin(\theta)=\frac{y}{r}[/tex]

we have

[tex]x=6\ units,y=5\ units[/tex]

Applying the Pythagoras Theorem

[tex]r^{2}=x^{2}+y^{2}[/tex]

substitute

[tex]r^{2}=6^{2}+5^{2}[/tex]

[tex]r^{2}=61[/tex]

[tex]r=\sqrt{61}\ units[/tex] -----> the hypotenuse

substitute

[tex]sin(\theta)=\frac{5}{\sqrt{61}}[/tex]

Simplify

[tex]sin(\theta)=\frac{5\sqrt{61}}{61}[/tex]

Remember that the sin(theta) is negative

so

[tex]sin(\theta)=-\frac{5\sqrt{61}}{61}[/tex]

Part 2) Find the cosecant of angle theta

we know that

The function cosecant is equal to divide the hypotenuse by the opposite  side to the angle theta

[tex]csc(\theta)=1/sin(\theta)=\frac{r}{y}[/tex]

we have

[tex]sin(\theta)=-\frac{5}{\sqrt{61}}[/tex]

so

[tex]csc(\theta)=-\frac{\sqrt{61}}{5}[/tex]

Part 3) Find the cotangent of angle theta

we know that

The function cotangent is equal to divide the adjacent side to the angle theta by the opposite side to the angle theta

[tex]cot(\theta)=\frac{x}{y}[/tex]

we have

[tex]x=6\ units,y=5\ units[/tex]

substitute

[tex]cot(\theta)=\frac{6}{5}[/tex]

The exact values of sin theta, csc theta, and cot theta for a point (-6, -5) on the terminal side are -5/sqrt(61), sqrt(61)/-5, and 6/5 respectively.

In this problem we have a point (-6, -5) on the terminal side of theta. The x-coordinate corresponds to the cosine of theta and the y-coordinate corresponds to the sin theta.

Answer:

31.5 litres

Step-by-step explanation:

If Mel uses all 30 litres of yellow paint, then:

5 / 2 = 30 / x

5x = 60

x = 12

Mel would need 12 litres of blue paint, but she only has 9 litres.  So the amount of yellow paint she needs is:

5 / 2 = x / 9

2x = 45

x = 22.5

Mel will use 22.5 litres of yellow paint with 9 litres of blue paint to make a total of 31.5 litres of green paint.

She can make a maximum of 28 litres of green paint.

To find the maximum amount of green paint Mel can make with her yellow and blue paint, we must use the ratio of 5:2 (yellow to blue) given for mixing the green paint.

Firstly, calculate the number of batches of green paint that can be made with the available yellow paint:

Mel has 30 litres of yellow paint and needs 5 litres per batch of green paint, so she can make 30 ÷ 5 = 6 batches from the yellow paint.

Next, calculate the number of batches that can be made with the blue paint:

Mel has 9 litres of blue paint and needs 2 litres per batch of green paint, so she can make 9 ÷ 2 = 4.5 batches from the blue paint.

However, since we cannot have half a batch, the maximum number of full batches Mel can produce from the blue paint is 4.

The limiting reactant here is the blue paint since it allows fewer batches to be made. Therefore, Mel can only make 4 full batches of green paint.

To find the total amount of the green paint from the batches:

Combine the ratios, which add up to 7 parts (5 parts yellow and 2 parts blue).

Multiply the number of batches by the sum of the parts: 4 batches × 7 parts per batch = 28 litres of green paint.

Thus, the maximum amount of green paint Mel can make is 28 litres.

The third option,

c) [tex]h(x)=2.25x-22[/tex]

We are given the functions E(x) and K(x), since they both are function of the same variable, we need to calculate the difference between them.

From the statement we know the functions:

[tex]f(x)=9.75x+62[/tex]

and

[tex]g(x)=7.5x+84[/tex]

So, calculating the difference the functions we have:

[tex]h(x)=f(x)-g(x)[/tex]

[tex]h(x)=(9.75x+62)-(7.5x+84)[/tex]

[tex]h(x)=(9.75x+62)-(7.5x+84)[/tex]

[tex]h(x)=9.75x-7.5x+62-84[/tex]

[tex]h(x)=2.25x-22[/tex]

Have a nice day!

Answer: Option C

[tex]h(x)=2.25x-22[/tex]

Step-by-step explanation:

To find the function h(x) that models the difference between Hector's and Cari's gains, subtract the functions f(x) with g(x)

That is to say:

[tex]h (x) = f (x) -g (x)[/tex]

We know that

[tex]f (x) = 9.75x + 62\\\\g (x) = 7.5x + 84[/tex]

Then we can find the function h(x)

[tex]h(x) = 9.75x + 62 - (7.5x + 84)\\\\h(x) = 9.75x + 62 -7.5x -84[/tex]

[tex]h(x)=2.25x-22[/tex]

Therefore, Option ( C ),P(Microbial Contamination from Salmonella | Capsule A)=0.31%

The probability of capsule B having microbial contamination is greater than the probability of capsule D having it.

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

It is given that the table shows the probabilities of contamination in medicine capsules from the presence of heavy metals and different types of microbes.

Now, By given table, we have;

The probability of capsule B having microbial contamination is, 0.33%

And, the probability of capsule D having it is, 0.22%

Hence, The probability of capsule B having microbial contamination is greater than the probability of capsule D having it.

Above is the table of conditional probabilities of contamination from various sources given type of capsules.

P(Microbial Contamination from Salmonella | Capsule A)=0.31%

40% of the figure is shaded.

The image depicts many grids. These small squares has 10 rows and 10 columns. So, the total number of squares are:

10 x 10=100 squares.

Out of 100 squares, 4 rows and their 10 columns are shaded. So,

4*10=40 squares

So, 40 squares are shaded. To find the percentage we can use the formula:

Shaded/ Total Squares x 100

= 40/100 x 100

= 40%

Therefore, 40 percent of the figure is shaded.

To find what percent of a figure is shaded, calculate the shaded area divided by the total area and multiply by 100. In probability distributions, shading indicates the probability that a variable falls within a specific range, such as the 80th or 90th percentile of a distribution.

To determine what percent of the figure is shaded, one must first understand the concept of percentage calculations. The percentage is computed by dividing the part (shaded area) by the total area, then multiplying by 100. In the case of probability distributions, the shaded area represents a probability, such as the probability of a variable falling between two values, or the specific percentile of a distribution.

For example, if we have a graph with a horizontal axis for X, and we need to shade the region corresponding to a certain probability or percentile, we need to identify the region under the curve that equates to that percentage. This could involve calculating the area between two x-values or finding a value that corresponds to a given area under the curve, such as the 80th percentile or 90th percentile. To express the result as a percentage, multiply the probability by 100.

Sometimes, the question may provide specific conditions, such as indicating that the shaded area under one curve is equal to the area of another shape, like a rectangle or another curve. In this case, we can assume the two percentages are equal and express the probability of one as the same percentage as the other.
