Step-by-step explanation:

The value of Sin(90) is equal to 1.

In mathematics, trigonometric functions are real functions that relate an angle of a right-angled triangle to ratios of two side lengths. The six trigonometric functions are Sine, Cosine, Tangent, Secant, Cosecant, and Cotangent.

Given here: Sin(90) and to find the value using the unit circle

Rotate ‘r’ anticlockwise to form a 90° angle with the positive x-axis.

The sin of 90 degrees equals the y-coordinate(1) of the point of intersection (0, 1) of unit circle and r.

The value of sin 90 degrees can be calculated by constructing an angle of 90° with the x-axis, and then finding the coordinates of the corresponding point (0, 1) on the unit circle. The value of sin 90° is equal to the y-coordinate (1). ∴ sin 90° = 1.

Hence, Sin (90) is equal to 1.

Answer:

I would use elimination in this scenario. Because in both equations there is a coefficient on both variables, it would be difficult to isolate one variable and would leave the equation as a fraction. Instead, use elimination. Multiply the first equation by -15, which changes it to 10x + 225y = -90, and then subtract the second equation, thus cancelling out the 10x's and letting you solve for Y. Hope this helps!

Step-by-step explanation:

(a) To determine if the relationship between the amount of dry ingredients and the amount of wet ingredients is proportional, we need to check if the ratios of dry to wet ingredients are the same for each row of data. Let's calculate the ratios for the first three rows:For 2.5 cups of dry ingredients and 12.5 oz of wet ingredients:

Dry/wet = 2.5/12.5 = 0.2For 12.5 cups of dry ingredients and 15 oz of wet ingredients:

Dry/wet = 12.5/15 = 0.83For 3 cups of dry ingredients and 25 oz of wet ingredients:

Dry/wet = 3/25 = 0.12

Since the ratios are not the same for each row of data, we can conclude that the relationship between the amount of dry ingredients and the amount of wet ingredients is not proportional.(

b) We can set up a proportion using one of the ratios from part (a) to find the amount of dry ingredients needed for 7.5 oz of wet ingredients:

Dry/wet = 2.5/12.5Dry/7.5 = 2.5/12.5Dry = (2.5/12.5) * 7.5Dry = 1.5

Therefore, 1.5 cups of dry ingredients are needed for 7.5 oz of wet ingredients.

a

yes.  the dry ingredient amount is always five times the amount of the wet ingredients in oz.

12.5/2.5 = 5

15/3 = 5

25/5 = 5

b

5 * 7.5 = 37.5

note that because the units remain the same, we are able to continually use multplying by 5 to find the amount in cups from the amount in oz.  you could change cups to oz, but you would get a different number that you multiply by for using oz wet ingredients to oz dry ingredients.

hope this helps,

The function f(x)* = 1 + x^2 is defined for all real numbers x, so the domain is all real numbers, or (-∞, ∞).

In determining the function's output values, one must consider its collection of feasible results to extract the range. Reviewing f(x)* exhibits a minimum value of 1 due to x^2 being perpetually non-negative, while adding another factor merely preserves positivity.

Concurrently as x skyrockets, so too does the value of f(x)* given that approaching infinity generates infinitely larger powers than any constant coefficient subordinated by it. Consequently, the overall range of f(x)* becomes [1, ∞), enwrapping all feasible solutions equivalent or superior to 1.

By using the graph, the average rate of change of the function f from 2 to 5 is equal to -1.

In Mathematics, the average rate of change of f(x) on a closed interval [a, b] is given by this mathematical expression:

Average rate of change = [f(b) - f(a)]/(b - a)

Next, we would determine the average rate of change of the function f from the graph over the interval [2, 5]:

a = 2; f(a) = 4

b = 5; f(b) = 1

Substituting the given parameters into the average rate of change formula, we have the following;

Average rate of change = (1 - 4)/(5 - 2)

Average rate of change = -3/3

Average rate of change = -1.

Answer:

AB = 28 , BC = 17.5 , X = 13.2

Step-by-step explanation:

since the figures are similar then the ratios of corresponding sides are in proportion, that is

\(\frac{AB}{PQ}\) = \(\frac{AD}{PS}\) ( substitute values )

\(\frac{AB}{8}\) = \(\frac{14}{4}\) ( cross- multiply )

4 AB = 8 × 14 = 112 ( divide both sides by 4 )

AB = 28

and

\(\frac{BC}{QR}\) = \(\frac{AD}{PS}\) ( substitute values )

\(\frac{BC}{5}\) = \(\frac{14}{4}\) ( cross- multiply )

4 BC = 5 × 14 = 70 ( divide both sides by 4 )

BC = 17.5

similarly for the 2 similar figures

\(\frac{x}{6}\) = \(\frac{11}{5}\) ( cross- multiply )

5x = 6 × 11 = 66 ( divide both sides by 5 )

x = 13.2

Answer:

\(\overline{AB}=28\)

\(\overline{BC}=17.5\)

\(x=13.2\)

Step-by-step explanation:

If quadrilateral PQRS is similar to quadrilateral ABCD, their corresponding sides are in the same ratio:

\(\overline{PQ} : \overline{AB} = \overline{QR} : \overline{BC} = \overline{RS} : \overline{CD} = \overline{SP}:\overline{DA}\)

From inspection of the two quadrilaterals, the given side lengths are:

\(\overline{PQ} = 8\)

\(\overline{QR} = 5\)

\(\overline{RS} = 6\)

\(\overline{SP} = 4\)

\(\overline{DA} = 14\)

Substitute these into the ratio equation:

\(8 : \overline{AB} = 5 : \overline{BC} = 6 : \overline{CD} = 4:14\)

Solve for AB:

\(8 : \overline{AB} = 4:14\)

   \(\dfrac{8}{\overline{AB}}= \dfrac{4}{14}\)

 \(8 \cdot 14=4 \cdot{\overline{AB}}\)

   \(\overline{AB}=\dfrac{8 \cdot 14}{4}\)

  \(\boxed{\overline{AB}=28}\)

Solve for BC:

\(5 : \overline{BC} = 4:14\)

  \(5 \cdot 14=4 \cdot \overline{BC}\)

    \(\overline{BC}=\dfrac{5 \cdot 14}{4}\)

   \(\boxed{\overline{BC}=17.5}\)

\(\hrulefill\)

Assuming the two figures are similar, their corresponding sides are in the same ratio. Therefore:

\(x:6=11:5\)

   \(\dfrac{x}{6}=\dfrac{11}{5}\)

   \(x=\dfrac{11 \cdot 6}{5}\)

   \(x=\dfrac{66}{5}\)

  \(\boxed{x=13.2}\)

To find the average rate of change on the interval [2,2+h],

Answer:

the collection center should be located at Collection Option (D).

Step-by-step explanation:

To determine the best location for the collection center, you can calculate the average coordinates of the four collection points and choose the location that is closest to this average.

To calculate the average coordinates, you can add the coordinates of each collection point and divide the result by the number of collection points. For example, to find the average X coordinate, you can add the X coordinates of all four collection points and divide by 4. Similarly, to find the average Y coordinate, you can add the Y coordinates of all four collection points and divide by 4.

Using this method, the average coordinates for the four collection points are (5.75,3.25). The collection point that is closest to these average coordinates is Collection Point D, which is located at (7,3). Therefore, the collection center should be located at Collection Point D.

I hope this helps to clarify the process for determining the best location for the collection center. Please let me know if you have any other questions.

The probability that Kyle takes at least one purple ball is 0.9

Probability is used to measure the likelihood of an event given a set of circumstances.

The probability that Kyle takes at least one purple ball is calculated by the formula P(A) = 1 – P(A’).

In this scenario, A is the event of taking at least one purple ball and A’ is the event of not taking any purple balls.

The probability of taking at least one purple ball (A) is calculated by subtracting the probability of not taking any purple balls (A’) from 1.

There are 20 balls in the bag, 18 of which are purple. This means the probability of not taking any purple balls (A’) is 2/20 = 0.1.

Therefore, the probability of taking at least one purple ball (A) is

1 – 0.1 = 0.9.

In conclusion, the probability that Kyle takes at least one purple ball is 0.9.
