525 is the constant of proportionality

Step-by-step explanation:

Answer:

y = 189.8

Step-by-step explanation:

Apply trigonometric function to find y.

Reference angle (θ) = 50°

Adjacent side = 122

Hypotenuse = y

Apply CAH, since the Hypotenuse and the Adjacent are involved.

Thus:

Cos θ = Adj/Hypo

Plug in the values

Cos 50° = 122/y

y*Cos 50° = 122

y = 122/cos 50°

y = 189.8 (beater tenth)

The value of x is 24/7, by setting up and solving a proportion based on the fact that the two triangles in the figure are similar.

To find the value of x, we need to use the fact that the two triangles in the figure are similar. This means that the corresponding angles are equal, and the corresponding sides are in proportion.

We can see that the angle marked y is the same in both triangles. Therefore, we can set up the following proportion:

x / 8 = 12 / (12 + 16)

Simplifying the right-hand side, we get:

x / 8 = 12 / 28

Multiplying both sides by 8, we get:

x = 8 × (12 / 28)

Simplifying the right-hand side, we get:

x = 96 / 28

Dividing both the numerator and denominator by their greatest common factor, which is 4, we get:

x = 24 / 7

Therefore, the value of x is 24/7.

Answer:

A: numerical

B:catergorical

C:catergorical

Step-by-step explanation:

Functions f(x) = x² + 1 and g(x) = x – 4, the value equivalent  to f(g(10)) is, 37

Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).

Vertical line test:-

Whenever we want to check whether a given expression is a function or not we can apply a vertical line test, in this test we check for a single image of x , we are getting a single image or more.

If we get more images then it will not be a function.

For example, let us take, y² = 4ax

y = ±√4ax

For single value of x we get two values of y

Hence, it will not be a function.

Given that,

f(x) = x² + 1

g(x) = x – 4

f(g(10)) = ?

f(g(x))  =  (x - 4)² + 1

           =  x² - 8x + 16 +1

           =   x² - 8x + 17

f(g(10)) =  10² - 8×10 + 17

            = 100 - 80 + 17

            = 37

The value of  f(g(10)) is 37

Missy will need a minimum of 570 square inches of wrapping paper to completely cover the box.

To calculate the minimum amount of wrapping paper needed to cover the box, we need to find the surface area of the box.

A rectangular box has six sides: a top, a bottom, two sides, and two ends.

The top and bottom sides have the same dimensions, which are 17.5 inches by 10 inches. So each of these sides has an area of 17.5 in × 10 in = 175 square inches.

The two side surfaces also have the same dimensions, which are 17.5 inches by 4 inches.

Each of these sides has an area of 17.5 in × 4 in = 70 square inches.

The two end surfaces have the same dimensions, which are 10 inches by 4 inches. Each of these sides has an area of 10 in × 4 in = 40 square inches.

To find the total surface area of the box, we add up the areas of all six sides:

175 in² (top) + 175 in² (bottom) + 70 in² (side 1) + 70 in² (side 2) + 40 in² (end 1) + 40 in² (end 2)

ANSWER

Arithmetic sequence. Common difference: (t - s)

EXPLANATION

The terms for a geometric sequence has this form:

So a = a1. In this case a = s. If this sequence were geometric, the second term should involve s. Therefore, it's not geometric.

The terms for an arithmetic sequence are:

The first term is also a = a1. In tihs case, the first term is s, so a = s

Assuming this is an arithmetic sequence, a2 = t. With this we can look for d, the common difference:

If d = (t-s), then the third term is:

Which is the same as the 3rd term of the given sequence. Therefore this is an arithmetic sequence and the common difference is (t - s)

Answer:

8/3

Step-by-step explanation:

Its simple, you are just taking the ratio and instead of the : ur putting a fraction. So it would be 8/3

Step-by-step explanation:

First equation: x-15=5

x-15+15=5+15

The answer will be x=20

Second equation: 2x+5=1

2x+5-5=1-5

2x=-4

Divide both sides by 2

The answer will be x=-2

Answer:

\(\huge\boxed{x = 20; x=-2}\)

Step-by-step explanation:

In equations, you can perform any operation (with a few exceptions), as long as it is to both sides of the equation.  As such, when approached with a problem such as x-15 = 5, isolate the variable, by adding 15 to both sides, changing the problem to x - 15 + 15 = 5 + 15.  Then, because -15 + 15 = 0, it becomes x + 0 = 5 + 15 --> x = 20.

In the other scenario: 2x + 5 = 1:

2x + 5 - 5 = 1 - 5

2x = -4

2x ÷ 2 = -4 ÷ 2

x = -2

Answer: 19.6

Step-by-step explanation:

The correct statement is that the theoretical probability of swimming, P(swimming), is one half, but the experimental probability is 16 over 40.

We know that there are 40 students at summer camp who are divided into two groups for either swimming or hiking. Each camper flips a coin, where heads represents swimming and tails represents hiking. The outcome frequency for swimming is 16 and for hiking is 24.
To compare the probabilities, we need to first understand the difference between theoretical probability and experimental probability. Theoretical probability is the expected probability of an event occurring based on mathematical calculations and assumptions, whereas experimental probability is the actual observed probability of an event occurring based on data from experiments or observations.
Option 1 states that the theoretical probability of swimming is one half, but the experimental probability is 24 over 40. This statement is incorrect because the theoretical probability of swimming is actually 50%, which is equal to one half, and the experimental probability of swimming is also 40%, which is equal to 16 over 40. Therefore, this option is false.
Option 2 states that the theoretical probability of swimming is one half, but the experimental probability is 16 over 40. This statement is correct because the theoretical probability of swimming is 50%, which is equal to one half, and the experimental probability of swimming is also 40%, which is equal to 16 over 40. Therefore, this option is true.
Option 3 states that the theoretical probability of swimming is 16 over 24, but the experimental probability is one half. This statement is incorrect because the theoretical probability of swimming is actually 50%, which is not equal to 16 over 24, and the experimental probability of swimming is also 40%, which is not equal to one half. Therefore, this option is false.
Option 4 states that the theoretical probability of swimming is 24 over 40, but the experimental probability is one half. This statement is incorrect because the theoretical probability of swimming is actually 50%, which is not equal to 24 over 40, and the experimental probability of swimming is also 40%, which is not equal to one half. Therefore, this option is false.
In conclusion, the correct statement is that the theoretical probability of swimming, P(swimming), is one half, but the experimental probability is 16 over 40.

The value of the x for the given angles will be 37°.

The alternate interior angles are the angles formed inside two parallel lines when they are intersected by a transversal and are equal to their alternate pairs.

It is given that the one angle is 143° made by the transversal line.

The value of the other angle by the application of the supplementary angle property will be,

143 + x' = 180

x' = 180 - 143

x' = 37°

Since, the value of angle x and angle x' will be the same as they are alternate angles,

x = x' = 37°

Therefore, the value of the x will be 37°.

Step-by-step explanation:

instantaneous rate of change of the search length 0.1667 seconds per

We need to take the derivative of the function S(n) with respect to n and evaluate it at n=12 in order to determine the instantaneous rate of change of the search length for a set of 12 articles.

Taking the derivative of S(n) with respect to n using the chain rule, we get:

S'(n) = 1.6 * (1/(0.8n)) * 0.8 = 2/n

Evaluating this expression at n=12, we get:

S'(12) = 2/12 = 0.1667 seconds per article

This indicates that the search time will increase by approximately 0.1667 seconds per article if the set contains 12 articles by one unit. Alternately, the search time per article will decrease by approximately 0.1667 seconds if the set's number of articles decreases by one unit from 12.

Therefore, the units for the instantaneous rate of change are "seconds per article", indicating the change in search time for each additional or fewer article in the set.

There are 5 possible combinations for Jacob's lock combination with increasing digits from left to right, and the product of the digits being 84.

Multiplication is a mathematical operation that involves combining two or more quantities to find their total or product. It is often represented by the "x" symbol or the multiplication sign "⋅". Multiplication is a fundamental operation in arithmetic and is used to calculate the total or result of repeated addition or groups of equal quantities.

The product of the digits being 84 implies that the possible combinations of digits are limited to those whose product is 84. The prime factorization of 84 is 2^2 * 3 * 7. Since the digits must be increasing from left to right and cannot repeat, the possible combinations of digits are:

1, 2, 42

1, 3, 28

1, 4, 21

2, 3, 14

Answer:

y = 1x + -3

Step-by-step explanation:

y=mx + b where m is the slope and b is the y intercept.

The y intercept is -3.

Let's calculate the slope. Pick 2 points. I'll choose (0,-3) and (3,0).

The slope should be positive; our line is pointing UP and as x increases, y increases.

Slope = rise/run = (y2-y1)/(x2-x1)

= (-3-0)/(0-3)

= -3/-3 = 1

So y = 1x + -3

We can try another point from the graph to check that we're right. Let's use (1,-2)

y = 1(1) +-3

y = 1-3

y = -2, which is exactly our coordinate from the graph.
