Step-by-step explanation:

In a right-angled triangle, by definition:

sinX = opposite side / hypothesis

= 5/13

tanX = opposity side / adjacent side

= 5/12

cosX = adjacent side / hypothesis

= 12/13

\(\\ \rm\hookrightarrow sinX=\dfrac{Perpendicular}{Hypotenuse}=\dfrac{5}{13}\)

\(\\ \rm\hookrightarrow cosX=\dfrac{Base}{Hypotenuse}=\dfrac{12}{13}\)

\(\\ \rm\hookrightarrow tanX=\dfrac{sinX}{cosX}=\dfrac{5}{12}\)

The aforesaid issue is easily resolved by doing the following:

Considering that,

Four Bs are worth three As.

It can be written as;

3A = 4B

determining B's value

B = 3A/4 (Equation 1) (Equation 1)

Now,

A B is worth five Cs.

So, 5B = C (Equation 2) (Equation 2)

Calculating B's value in equation 1

= 15A/4 = C

= 4C = 15A

2C = (15/2)A

2C = 7.5A

Therefore, the solution is 2C = 7.5A

The quadratic function of the distance of the diver from sea level is: d(t) = -2(t - 3)^2 - 8

A quadratic function can be represented in the form of d(t) = a(t - h)^2 + k where a is the leading coefficient, (t - h) is the horizontal shift, and k is the vertical shift.

To find this quadratic function, we need to find the values of a, h, and k.

To find the vertex, we can use the point where the diver reaches the maximum depth, which is 8 meters at 3 minutes,

So the vertex is at (h, k) = (3, -8).

When the time are converted to minutes:

To find the value of a, we can use the point (2,-10) and the vertex form equation:

d(t) = a(t - h)^2 + k

Substitute the coordinates of the point and the vertex form equation:

-10 = a(2-3)^2 -8

Solving the system of equation, we find a = -2

Therefore, the quadratic function is: d(t) = -2(t - 3)^2 - 8

Answer:

It would take 19 hours and 36 minutes until there are 1040 bacteria present.

Step-by-step explanation:

Given that in a lab experiment, 610 bacteria are placed in a petri dish, and the conditions are such that the number of bacteria is able to double every 23 hours, to determine how long would it be, to the nearest tenth of an hour, until there are 1040 bacteria present, the following calculation must be performed:

610X = 1040

X = 1040/610

X = 1.7049

2 = 23

1.7049 = X

1.7049 x 23/2 = X

39.2131 / 2 = X

19.6 = X

100 = 60

60 = X

60 x 60/100 = X

36 = X

Therefore, it would take 19 hours and 36 minutes until there are 1040 bacteria present.

The measures of the angles are 33°, 105° and 42°

We can call the top angle P, the bottom left angle Q, and the bottom right angle R. We are also given that angle P is (x - 9) degrees, angle Q is (x + 63)  degrees, and angle R is x degrees.

Now, we can use the fact that the sum of the angles in a triangle is 180 degrees to set up an equation:

Angle P + Angle Q + Angle R = 180

To find Angle, we can use the fact that the sum of the angles in a straight line is 180 degrees. We can see that Angle and Angle A are on a straight line, so we have:

(x – 9) + ( x + 63) +  x = 180

=> 3x + 54 = 180

=> 3x = 126

=> x = 42

We can now use this value to find the measures of the angles.

Angle P is (x -9) degrees, so Angle P = 42 - 9 = 33 degrees.

Angle Q is (x + 63) degrees, so Angle Q = 42 + 63 = 105 degrees.

Angle R is x degrees, so Angle R = 42 degrees.

An order-preserving function is a function that preserves the order of its inputs. In other words, if x is less than y, then f(x) will be less than f(y).

The statement "f is order-preserving if x < y implies f(x) < f(y)" means that if x is less than y, then f(x) must be less than f(y). This is a necessary condition for a function to be order-preserving. However, it is not a sufficient condition. For example, the function f(x) = x^2 is not order-preserving, because 2 < 3, but f(2) = 4 > f(3) = 9.

In summary, order-preserving functions are useful in situations where we need to preserve the order of a set of data.

Answer:

25 percent of 68 equals 17.

Step-by-step explanation:

Angle a + Angle d = 180 degreesAngle b + Angle c = 180 degrees.

In a parallelogram, adjacent angles are supplementary. As a result, we can express c in terms of the angles adjacent to it as follows: Angle a + Angle c = 180 degreesAngle c + 46 degrees = 180 degreesAngle c = 180 degrees - 46 degrees = 134 degreesTherefore, the size of angle c is 134 degrees.

A parallelogram is a four-sided quadrilateral that has opposite sides parallel and equal in length. Each of the opposite angles is also equal in size.In general, if we label the angles of a parallelogram as follows: Angle a, Angle b, Angle c, and Angle d,.

we have the following:Angle a = Angle c (opposite angles are equal)Angle b = Angle d (opposite angles are equal)Adjacent angles in a parallelogram are supplementary, which means they add up to 180 degrees.

Step-by-step explanation:

In this scenario, the confidence interval represents the possible range of differences in the proportion of employees who skip breakfast when free breakfast is offered and when it's not. A confidence interval that does not include zero indicates that there is statistically significant evidence to suggest a difference in proportions between these two groups.

Therefore, for the first interval (-0.44,-0.16), since it does not include zero, we can be confident that offering free breakfast results in a decrease in the proportion of employees who skip breakfast.

For the second interval (-0.25, 0.05), since it contains zero, we cannot be confident that there is a difference in the proportion of employees who skip breakfast between the two groups.

Similarly, for the third interval (-0.23, 0.15), since it contains zero, we cannot be confident that there is a difference in the proportion of employees who skip breakfast between the two groups.

So, the correct answer is:

For the interval (-0.44,-0.16), we can be confident that employees will skip breakfast less when free breakfast is offered than when it's not.

For the intervals (-0.25, 0.05) and (-0.23, 0.15), our confidence interval shows that there could be no difference in the proportion of employees who skip breakfast.

Answer:

108 in²

Explanation:

The area of the recycled part can be calculated as the difference between the area of the sheet of paper and the area of the triangle.

So, the area of the sheet of paper can be calculated as:

Ar = Base x Height

Ar = 10 in x 12 in

Ar = 120 in²

Then, the area of the triangle can be calculated as:

At = (1/2) x Base x Height

At = (1/2) x 6 in x 4 in

At = 12 in²

Therefore, the area of the recycled part is equal to:

A = Ar - At

A = 120 in² - 12 in²

A = 108 in²

So, the answer is 108 in²

In linear equation, 9 is the constant of variation k.

What in mathematics is a linear equation?

An algebraic equation with simply a constant and a first-order (linear) component, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation.

                             Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables. Equations with variables of power 1 are referred to be linear equations. axe+b = 0 is a one-variable example in which a and b are real numbers and x is the variable.

given x varies inversely with y then

xy = k ← k is the constant of variation

to find k use the condition x = - 4 when y = - 9, hence

k = -4 × -9 = 36

 x = 36/y

 when x = 4 , then  y = 36/4

The true statements are

The value of f(–10) = 82

The graph of the function is a parabola.

The graph contains the point (20, –8).

A parabola is a type of conic section that is formed when a plane intersects a cone in such a way that the angle between the plane and the vertical axis of the cone is equal to the angle between the plane and a generator (a straight line passing through the vertex and the base of the cone).

The resulting shape is a symmetrical, U-shaped curve. The standard form of the parabola is a quadratic function.

Here we have

The quadratic function f(x) = x²/5 – 5x + 12

Now check each option as follows

1. The value of f(–10) = 82

To check this find f(-10) as follows

f(-10) =1/5 (-10)²– 5(-10) + 12 = 20 + 50 + 12 = 82

Hence, The value of f(–10) is equal to  82

2. The graph of the function is a parabola.

As we know the standard equation of a parabola is a quadratic function that is in the form of ax² + bx + c

Hence, the quadratic function represents a parabola

3. The graph of the function opens down.

In the given function f(x) = x²– 5x + 12, the coefficient of the x² term is 1. Since the coefficient of x² is positive, the parabola opens upwards.

Hence, The graph of the function opens down is false

4. The graph contains the point (20, –8).

To check this substitute the point in f(x)

=> –8 = 1/5(20)²– 5(20) + 12

=> –8 = 80 – 100 + 12

=> –8 = –8   [ Which is true ]

Hence, The graph contains the point (20, –8).

5. The graph contains the point (0, 0).

=>  0 = (0)²– 5(0) + 12

=>  0 = 12   [ which is not true ]

Hence, The graph doesn't contain the point (0, 0).

Therefore,

The true statements are

The value of f(–10) = 82

The graph of the function is a parabola.

The graph contains the point (20, –8).
