The graph of the parent absolute value function is decreasing over the interval (-∞, 0). The function exhibits a decreasing behavior as x moves from negative infinity towards zero, where the absolute value decreases.

The parent absolute value function is defined as f(x) = |x|. To determine where the graph of this function is decreasing, we need to identify the intervals where the function's slope is negative.

Let's analyze the behavior of the parent absolute value function:

For x < 0, the function can be rewritten as f(x) = -x. In this interval, the function is a linear function with a negative slope of -1. As x decreases, f(x) also decreases, indicating a decreasing behavior.

For x > 0, the function remains f(x) = x. In this interval, the function is a linear function with a positive slope of 1. As x increases, f(x) also increases, indicating an increasing behavior.

At x = 0, the function is not differentiable since the slope changes abruptly from negative to positive. However, it is worth noting that the function does not strictly decrease or increase at x = 0.

Therefore, we can conclude that the graph of the parent absolute value function is decreasing over the interval (-∞, 0).

In this interval, as x moves from negative infinity towards zero, the function values decrease. The farther away x is from zero (in the negative direction), the larger the absolute value, resulting in a decrease in the function values.

On the other hand, the graph of the parent absolute value function is increasing over the interval (0, ∞), as explained earlier.

Answer:

it will be 14.14

Step-by-step explanation:

you have to find the square root

Answer:

m∠B = 43°

b = 26.1

c = 38.3

Step-by-step explanation:

By applying triangle sum in the given triangle,

47° + 90° + m∠B = 180°

137° + m∠B = 180°

m∠B = 43°

By applying sine ratio to the angle measuring 47°.

sin(47°) = \(\frac{\text{Opposite side}}{\text{Hypotenuse}}\)

            = \(\frac{28}{c}\)

c = \(\frac{28}{\text{sin}(47^{\circ})}\)

c = 38.28

c ≈ 38.3

By applying cosine rule,

cos(47°) = \(\frac{\text{Adjacent side}}{\text{Hypotenuse}}\)

             = \(\frac{b}{c}\)

             = \(\frac{b}{38.3}\)

b = 38.3[cos(47°)]

b = 26.1

The property that should be used to continue simplifying the above equation is A-^1A = 1. So, correct option is C.

We can start with the equation AB = AC and multiply both sides by A^-1 on the left:

A^-1(AB) = A^-1(AC)

Using the associative property of matrix multiplication, we can simplify the left-hand side:

(A^-1A)B = (A^-1A)C

Using the fact that A^-1A = I (the identity matrix), we get:

IB = IC

Simplifying further using the fact that I times any matrix is that matrix itself, we obtain:

B = C

Therefore, the equivalent equation to AB = AC using A^-1 that simplifies to B = C is A^-1(AB) = A^-1(AC), and the property used to continue simplifying the equation is A^-1A = I.

The correct option is (C) A^-1A = 1, which is equivalent to A^-1A = I, since the identity matrix is denoted as 1 in some contexts.

Two terms, \(-4z^2\) and \(-5z^2,\) both involving the variable z of degree 2, form an equation. We combine these similar concepts to make the expression more concise.

Adding or deleting terms raised to the same power(s) with the same variable(s) is known as combining like terms. Since both terms contain z2 in this example, we can add them.

The example of systematic sampling is option c) in a population of 1000 at a school, every 64th person is chosen.

In systematic sampling, the population is first divided into a sampling frame (for example, a list or a map) and then every kth individual is selected from the list. In this example, every 64th person is chosen from the list of 1000 individuals, which is an example of systematic sampling. In the example given, there is a list of 1000 individuals, and every 64th person is chosen from the list. This means that the sampling interval k is 64, and the first individual is selected randomly from the first 64 individuals in the list. From then on, every 64th individual is selected to be included in the sample.

Answer:

The temperature at the start is 35F

The temperature of the room is 74F

Step-by-step explanation:

Given

\(T(m) = 74 - 39(0.87)^m\)

Solving (a): The temperature at the start.

To do this, we set: \(m = 0\)

So, we have:

\(T(0) = 74 - 39(0.87)^0\)

\(T(0) = 74 - 39*1\)

\(T(0) = 74 - 39\)

\(T(0) = 35\)

Hence, the temperature at the start is 35F

Solving (b): The room temperature

We have:

\(T(m) = 74 - 39(0.87)^m\)

To get the temperature of the room, we simply remove the exponential function.

So, we have:

\(Initial = 74\)

Hence, the temperature of the room is 74F

The initial temperature of the liquid is 35 F and the room temperature is 74 F.

The melting point is the temperature at which the solid starts converting into liquid.

Given here,

\(T_m = 74- 39(0.87)^m\)

Leat the \(m = 0,\)

So,

\(T_0 = 74- 39(0.87)^0\\\\T_0 = 35 \rm \ F\)

Thus the initial temperature is 35 F.

Now remove the exponential to get the room temperature,

So,

\(T_{RT} = 74\)

Therefore, the initial temperature of the liquid is 35 F and the room temperature is 74 F.

Of means multiply

84 % * 300

Change to decimal form

.84 * 300

252

Step-by-step explanation:

You need to set up a proportion. Percents always over percents, so our first fraction would be \(\frac{84}{100}\), which just means that out of 100%, we are given 84. We need to find a variable to solve for: x. We need to find the number that is 84% of 300, which means that 300 is 100%. Knowing this, it would be in the denominator, since both 100 and 300 are 100% of something. This would give us the fraction \(\frac{84}{100} = \frac{x}{300}\). I like to use the cross-multiply method, which just means you multiply by a diagonal and then divide by what's left. This would give us 300 x 84 = 25,200/100 = 252. Hope this helps!

A function f such that f '(x) = 3x^3 and the line 81x + y = 0 is tangent to the graph of f is f(x) = 3x^4/4 + 729/4.

In the given question, we have to find a function f such that f'(x) = 3x^3 and the line 81x + y = 0 is tangent to the graph of f.

The given function is f'(x) = 3x^3.

No integrating on both side,

f(x) = \(\int3x^3dx\) + C

f(x) = 3x^4/4 + C

As given, the line 81x + y = 0 is tangent to the graph of f.

So, slope at point of tangent; f'(x) = -81

So, 3x^3 = -81

Divide by 3 on both side, we get

x^3 = -27

Taking cube root on both side, we get

x = -3

So putting the value of x in 81x + y = 0, we get

y = 243

Thus, f(x) passes through (-3, 243).

So, 243 = 3/4(81) + C

Multiply by 4 on both side, we get

972 = 243 + 4C

Subtract 243 on both side, we get

4C = 729

Divide by 4 on both side, we get

C = 729/4

The equation of the line in standard form that satisfies the provided conditions is 6x - y = -2.

To obtain the equation of a line in standard form that satisfies the provided conditions, we'll first convert the provided equations into slope-intercept form (y = mx + b), where m represents the slope and b represents the y-intercept.

1. We have the equation:

  6x - y = 5

  Subtract 6x from both sides:

  -y = -6x + 5

  Multiply through by -1 to isolate y:

  y = 6x - 5

  From this equation, we can see that the slope is 6.

2. We have the equation:

  4y - 9x = 8

  Add 9x to both sides:

  4y = 9x + 8

  Divide through by 4 to isolate y:

  y = (9/4)x + 2

  From this equation, we can see that the y-intercept is 2.

Now, we have the slope (m = 6) and the y-intercept (b = 2).

We can substitute these values into the standard form equation of a line, which is Ax + By = C, to obtain the equation in standard form.

Using the slope-intercept form equation (y = mx + b), we can rewrite it as -mx + y = b.

Rearranging, we get mx - y = -b.

Substituting the provided values:

6x - y = -(2)

Multiplying through by -1 to make the leading coefficient positive, we have:

-6x + y = 2

Now, rearranging the terms to obtain the standard form Ax + By = C, we get:

The coordinates of the midpoint M are (-1, 4).

To find the midpoint M of the line segment AB with endpoints A(2, 1) and B(-4, 7), we can use the midpoint formula.

The midpoint formula states that the coordinates of the midpoint M(x, y) of two points A(x₁, y₁) and B(x₂, y₂) can be found by taking the average of their respective x-coordinates and y-coordinates:

x = (x₁ + x₂) / 2

y = (y₁ + y₂) / 2

Let's apply the formula to find the midpoint M of AB:

x = (2 + (-4)) / 2

= -2 / 2
