A club had 600 members. 60% of them were males. When 200 new members joined the club, the percentage of male members was reduced to 50%. How many of the new members were males?

Answer:   To find the time at which the temperature is maximum, we need to find the vertex of the quadratic function T(x) = -0.07x^2. Recall that the x-coordinate of the vertex of a quadratic function f(x) = ax^2 + bx + c is given by -b/2a. In this case, a = -0.07 and b = 0 (since there is no linear term), so the x-coordinate of the vertex is x = -b/2a = -0/(-0.14) = 0.

Since x is the number of hours after 6 a.m., the time corresponding to x = 0 is 6 a.m. Therefore, the temperature is a maximum at 6 a.m.

To find the maximum temperature, we evaluate T(0) = -0.07(0)^2 = 0. Therefore, the maximum temperature is 0 degrees Fahrenheit. Note that this result makes sense, since the quadratic function T(x) = -0.07x^2 is a downward-facing parabola, which means that the temperature decreases as the number of hours after 6 a.m. increases.

Step-by-step explanation:

The probability of picking a 7 and then picking a 7 is 8.33%.

Since we are not replacing the first card before drawing the second one, the probability of drawing a 7 on the first card is 1/4. After drawing the first card, there are three remaining cards, and only one of them is a 7. Therefore, the probability of drawing a 7 on the second card given that the first card was a 7 is 1/3.

Using the multiplication rule of probability, the probability of drawing a 7 on the first card and then drawing a 7 on the second card without replacement is

P(7 on the first card) x P(7 on the second card | 7 on the first card) = (1/4) x (1/3) = 1/12

P(7 on the first card and then a 7 on the second card) = 1/12 x 100% = 8.33%

An equation is a mathematical statement that shows that two expressions are equal. It typically includes variables, constants, and mathematical operators such as addition, subtraction, multiplication, and division. Equations can be used to model a wide range of real-world situations, and they are an essential tool in many fields of study, including physics, engineering, and economics.

To solve for y, we need to isolate y on one side of the equation. We can do this by first distributing the 3 on the right-hand side:

24 = 3y + 18

Next, we can isolate 3y by subtracting 18 from both sides:

24 - 18 = 3y

6 = 3y

Finally, we can solve for y by dividing both sides by 3:

y = 2

Therefore, the solution to the equation 24 = 3(y + 6) is y = 2.

A diagonal is a line segment that connects two polygonal corners (vertexes), although it is not an edge (side). In other words, it connects any two polygonal vertices that are not neighboring. So, when we directly link any two vertices that are not connected by any sides, we may draw the diagonals in a polygon. A diagonal is a line that runs straight across the vertices of a polygon and joins its opposing corners. In other terms, a line segment connecting any two non-adjacent corners is a polygon's diagonal. Depending on how many sides a polygon has, distinct polygons may have a variable number of diagonals.

Given that the length of the wind chime is 16 inches thus,

Book value of ARL = Present value of estimated cash flows for ARL - Accumulated depreciation and amortization

PV = PMT x (1 - 1 / (1 + r)ⁿ) / r

The formula for weighted average is:

Weighted average = (Cash flow 1 x Probability 1) + (Cash flow 2 x Probability 2) + (Cash flow 3 x Probability 3)

PV = (700,000 x 0.25 x (1 - 1 / (1 + 0.08)⁵) / 0.08) + (750,000 x 0.4 x (1 - 1 / (1 + 0.08)⁵) / 0.08) + (850,000 x 0.35 x (1 - 1 / (1 + 0.08)⁵) / 0.08)

PV = $2,317,283.36

Since this is the end of the first year, the accumulated depreciation and amortization is simply the present value of the estimated cash flows for the first year:

Accumulated depreciation and amortization = (700,000 x 0.25 / (1 + 0.08)) + (750,000 x 0.4 / (1 + 0.08)) + (850,000 x 0.35 / (1 + 0.08))

Accumulated depreciation and amortization = $1,830,532.21

Finally, we can calculate the book value of the ARL at the end of one year:

Book value of ARL = Present value of estimated cash flows for ARL - Accumulated depreciation and amortization

Book value of ARL = $2,317,283.36 - $1,830,532.21

Book value of ARL = $486,751.15

Therefore, the book value of the asset retirement liability at the end of one year is $486,751.15.

Loss = Actual restoration costs - Book value of ARL

Loss = $796,000 - $486,751.15

Answer: V(x) = -5x^2 + 70x

Step-by-step explanation:

Let the length and width of the rectangular base be represented by x and y, respectively.

Since the perimeter of the rectangular base is 28 cm, we have:

2x + 2y = 28

x + y = 14

The height of the box is given as 5 cm.

The volume of the box is given by:

V = lwh = xy(5)

V = 5xy

We can solve for y in terms of x from the equation x + y = 14:

y = 14 - x

Substituting this into the equation for the volume, we get:

V = 5x(14 - x)

Simplifying:

V = 70x - 5x^2

The square of the binomial that represents the trinomial is [tex](0.1b+10c)^{2}[/tex], and the missing monomial is 10bc.

What is Trinomial ?

A trinomial is a polynomial that consists of three terms. In algebra, a term is a combination of a constant and one or more variables, multiplied together. A trinomial, therefore, is a polynomial that has three such terms.

To represent the trinomial 0.01[tex]b^{2}[/tex]+ ∗ +100[tex]c^{2}[/tex] as a square of a binomial, we need to find a monomial that can be added to it to form a perfect square trinomial.

To do this, we can take the square root of the first and last terms of the trinomial and multiply them together:

√(0.011[tex]b^{2}[/tex]) = 0.1b

√(100[tex]c^{2}[/tex]) = 10c

Multiplying these square roots together, we get:

0.1b * 10c = b * 1c * 10 = 10bc

So, the missing monomial is 10bc. Adding this monomial to the original trinomial gives us:

0.011[tex]b^{2}[/tex] + 10bc + 100[tex]c^{2}[/tex] =  [tex](0.1b+10c)^{2}[/tex],

Therefore, the square of the binomial that represents the trinomial is   [tex](0.1b+10c)^{2}[/tex], and the missing monomial is 10bc.

First, we need to find the cross-sectional area of each figure:

Since the cross-sectional areas are equal at every level, we can set up the following equation:

5x = 9π

Solving for x, we get:

x = 9π/5

Now, we can find the volume of the rectangular prism:

V = 5x * 8 = 72π cubic meters

And the volume of the cylinder:

V = π(3^2) * 8 = 72π cubic meters

Since the volumes are equal, we can set up the following equation:

72π = 72π

Simplifying, we get:

9πx = 40π

Solving for x, we get:

x = 40/9

Rounding to the nearest tenth, we get:

x ≈ 4.4 meters

Therefore, the width of the rectangular prism is approximately 4.4 meters.

The leading coefficient of the polynomial is 4.

The leading coefficient of a polynomial, we first need to understand what the leading term of the polynomial is.

The leading term is the term with the highest degree in the polynomial.

For example, in the polynomial [tex]3x^4 + 2x^3 - 5x^2 + 4x - 1[tex], the leading term is 3x^4.
To determine the leading coefficient of a polynomial, we simply look at the coefficient of the leading term. For example, in the polynomial [tex]3x^4 + 2x^3 - 5x^2 + 4x - 1[/tex], the leading coefficient is 3.
Now, let's apply this concept to the polynomial graphed below. From the graph, we can see that the polynomial has a degree of 2, meaning that the highest power of x in the polynomial is 2.

Therefore, the leading term of the polynomial is [tex]ax^2[/tex], where a is the leading coefficient.
The vertex is the point on the graph where the polynomial reaches its maximum or minimum value. In this case, the vertex is located at [tex](-2, 4)[/tex]
Since the vertex is the highest point on the graph, we know that the coefficient of x^2 must be positive.

In this case, the value of y at the vertex is 4.

Therefore, the leading coefficient of the polynomial is 4.

The average change in field position on each run was a loss of 7/4 yards.

A mixed number in mathematics is a number that combines a whole number and a fraction. The entire number and the fraction are often separated by a space or a plus sign when writing mixed numbers. As an illustration, the mixed number 2 1/3 stands for the sum of 2 and 1/3. By dividing the entire number by the fraction's denominator and adding the numerator, mixed numbers can be transformed into improper fractions. For instance, we would multiply 2 by 3 and add 1 to get 7, which is an incorrect fraction of 2 1/3. In order to obtain 7/3, we would then write the fraction using the same denominator as the original fraction.

The total change in position for a total loss of 15/3/4 yards is:

Total change in field position = - (15 + 3/4) yards

Given the, number of runs = 9

Thus:

Average change in field position = Total change in field position / Number of runs

Average change in field position = (- 15 - 3/4) yards / 9

To find approximately how many times larger an elephant is than a 5-year-old child, we need to know the mass of an elephant. According to National Geographic, an average elephant can weigh between 2,700 and 6,000 kg. Assuming an average weight of 4,350 kg for an elephant, we can calculate the ratio of elephant mass to child mass as follows:
