Step-by-step explanation:

When raising an exponential expression to a power, you need to multiply the exponents. Applying this rule to (y^3)^5, we get (y^3)^5 = y^(3*5) = y^15.

So, (y^3)^5 • y^4 = y^15 • y^4 = y^(15+4) = y^19.

Therefore, the simplified expression is y^19, and the answer is 2.

The formula for the Pythagorean theorem in 3 dimensions is [tex]d^2 = a^2 + b^2 + c^2.[/tex]

What is Pythagorean theorem?

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This can be extended to 3 dimensions using the same principle.

In the case of a cube with base a, width b, and height c, we can imagine a right triangle that is formed by one of the diagonals of the cube and one of the faces. Let d be the length of this diagonal.

By the Pythagorean theorem in 3 dimensions, we have:

[tex]d^2 = a^2 + b^2 + c^2[/tex]

To see why this is the case, imagine that we have a right triangle in three dimensions, with sides of length a, b, and c.

The hypotenuse of this triangle is the diagonal of a rectangular box with sides of length a, b, and c. By the Pythagorean theorem, the square of the length of the diagonal is equal to the sum of the squares of the lengths of the other two sides, which gives us the formula above.

The equation [tex]f(x) = -x^2 + 5x + 14[/tex] models the flight path of a quaffle thrown into the air during a game of quidditch.

The equation [tex]f(x) = -x^2 + 5x + 14[/tex] can be used to model the height of the quaffle, where x represents the time in seconds after the quaffle is thrown.

To find the maximum height of the quaffle, we need to find the vertex of the parabola described by the equation. The following formula can be used to determine the vertex's x-coordinate:

x = -b / 2a

where a, b, and c are the coefficients of the quadratic equation [tex]ax^2 + bx + c[/tex]. In this case, a = -1, b = 5, and c = 14, so we have:

x = -5 / 2(-1) = 5/2

The y-coordinate of the vertex can be found by plugging this value of x into the equation:

[tex]f(5/2) = -(5/2)^2 + 5(5/2) + 14 = 23.5[/tex]

Therefore, the maximum height of the quaffle is 23.5 feet, and it occurs 2.5 seconds after the quaffle is thrown.

5000 parts must be tooled by the machine to ensure 4500 are acceptable as One tenth of the parts tooled by a machine are rejects.

One-eighth of the parts tooled by a machine are rejected.

Now, let's take the number of parts made by the machine to be x.

Now, the number of acceptable parts will be:

Total number of parts - number of rejected parts

x - (x/10)

(10x-x)/10

9x/10

Now, we have the number of acceptable parts as 4500.

So, we have:

9x/10 = 4500

9x = 4500*10

x = (4500*10)/9

x = 5000

The correct statement is: The amplitude will decrease, and the sound will become quieter.

When the compressions in a sound wave are very close together, the amplitude of the wave decreases. Amplitude is the measure of the maximum displacement of the particles of the medium from their rest position.

a)The function that describes the height of the rocket in terms of time t can be expressed as: h(t) = -16t² + 224t + 98

b) the maximum height of the rocket is 1378 feet at t=7sec.

c)the rocket will be more than 702 feet above ground level during the time interval [1.95, 18.55].

d)14.13 seconds will take it to hit the ground

The quadratic formula is a formula that gives the solutions (or roots) of a quadratic equation of the form ax^2 + bx + c = 0, where a, b, and c are coefficients, and x is the variable:

x = (-b ± √(b² - 4ac)) / (2a)

a) The function that describes the height of the rocket in terms of time t can be expressed as:

h(t) = -16t² + 224t + 98

where h(t) represents the height of the rocket (in feet) at time t (in seconds).

The -16t² term represents the effect of gravity, which causes the rocket's height to decrease over time. The 224t term represents the initial velocity of the rocket, which causes its height to increase over time. The constant term 98 represents the initial height of the rocket (at t = 0).

b) To determine the time at which the rocket reaches its maximum height, we need to find the vertex of the parabolic function h(t). The x-coordinate of the vertex is given by:

t = -b / (2a)

where a = -16 (the coefficient of t²) and b = 224 (the coefficient of t). Substituting these values, we get:

t = -224 / (2×(-16)) = 7

Therefore, the rocket reaches its maximum height at t = 7 seconds.

To find the maximum height, we can substitute t = 7 into the function h(t) and simplify:

h(7) = -16(7)²+ 224(7) + 98 = 1378

Therefore, the maximum height of the rocket is 1378 feet.

c) To find the time interval during which the rocket is more than 702 feet above ground level, we need to solve the inequality:

h(t) > 702

Substituting the expression for h(t), we get:

-16t² + 224t + 98 > 702

Simplifying and rearranging terms, we get:

16t² - 224t - 604 < 0

Using the quadratic formula, we can solve for the roots of the equation:

t = [224 ± √(224²- 4(16)(-604))] / (2(16))

t ≈ 1.95 or t ≈ 18.55

Therefore, the rocket will be more than 702 feet above ground level during the time interval [1.95, 18.55].

d) To find the time at which the rocket hits the ground, we need to find the root(s) of the function h(t) where h(t) = 0. This occurs when the rocket returns to ground level (i.e., h(t) = 0) after reaching its maximum height.

Substituting the expression for h(t), we get:

-16t²+ 224t + 98 = 0

Using the quadratic formula, we can solve for the roots of the equation:

t = [224 ± √(224² - 4(-16)(98))] / (2(-16))

t ≈ 14.13 or t ≈ -0.38

the rocket hits the ground after approximately 14.13 seconds.

The measure of angle T in the given quadrilateral is 92.5 degrees.

A quadrilateral is said to be inscribed in a circle if all four of its vertices are located on the circumference of the circle. In other terms, the quadrilateral is "enclosed" by the circle. The opposing angles of a quadrilateral are supplementary (add up to 180 degrees) and the product of the measurements of the two diagonals equals the sum of the products of the measures of the pairs of opposite sides when a quadrilateral is inscribed in a circle, both of which are important features. Inscribed quadrilateral geometry difficulties can be resolved by using these characteristics.

The sum of the angles in a quadrilateral is 360 degrees.

angle R + angle S + angle T + angle U = 360 degrees

79 degrees + 96 degrees + x + angle U = 360 degrees

Angle T and angle U are opposite angles in quadrilateral RSTU, therefore congruent.

175 degrees + 2x = 360 degrees

2x = 185 degrees

x = 92.5 degrees

Short answer? x is 52 degrees and y is 38 degrees.

But how did I get it you probably did not ask?

Let's run it back to the definitions of complementary and supplementary angles.

Complementary angles: 2 angles that add to get you a CLEAN 90 degrees

Supplementary angles: 2 angles that add to get you a CLEAN 180 degrees

So if x is supplementary to 128 degrees, it has to be 52 degrees to fit the definition. So yeah 180-128= 52 degrees

Now for x to be complementary to y, y has to 38 degrees. 90-52=38 degrees.

The standard deviation for the given Poisson distribution is 0.8.

A Poisson distribution is used to model the number of events occurring in a fixed time interval when the events occur independently and at a constant rate. The mean and variance of a Poisson distribution are equal, and both are given by λ, the rate parameter.

Here, the given information is that the company receives an average of 0.64 purchase orders per minute. Therefore, λ = 0.64.

The formula for the variance of a Poisson distribution is σ² = λ, where σ is the standard deviation. Thus, substituting λ = 0.64 in this formula, we get σ² = 0.64. Taking the square root of both sides, we get σ = √0.64 = 0.8.

An equation in mathematics is a declaration of the equality of two expressions. Two sides of an equation are divided using the algebraic symbol (=). As an example, the assertion "2x + 3 = 9" is supported by the argument that it is true. Finding the value or values of the variable(s) needed to make the equation true is the aim of equation solving. It is possible to create regular or nonlinear, straightforward or complex equations that include one or more elements.

Let's name Waymon's usual hourly wage for the first 40 hours of labour "x". Based on the facts provided, we can then construct the following equation:

[tex]40x + 3(x + 1.5x) = 479.27[/tex]

Waymon's normal compensation for 40 hours of work is represented by the first term, while his overtime pay for 3 hours of work at time-and-a-half is represented by the second term (or 1.5 times his regular rate).

When we simplify this equation, we get:

[tex]40x + 4.5x = 479.27 - 48.4744.5x = 430.80 \\x = 9.68[/tex]

Waymon's hourly wage for the first 40 hours of labour was thus S9.68.
