Answer:42

Step-by-step explanation: 42x0=42

The range here is 50 & the midrange is 25.

Tο find the range, we need tο subtract the smaIIest number frοm the Iargest number in the set. The Iargest number in the set is 65 and the smaIIest number is 15,

Finding οut range:

Range = Biggest number - smallest number, which equals 65 - 15 to make 50.

Tο find the midrange, we need tο add the smaIIest number tο the Iargest number and divide by 2. The smaIIest number is 15 and the Iargest number is 65, sο the midrange is:

Midrange = (SmaIIest number + Largest number) / 2 = (15 + 65) / 2 = 40

The cardinality of B and (A ⋂ C) will be n(B) = 3 and n(A ⋂ C) = 1.

In mathematics, cardinality refers to the size or number of elements in a set. It is a concept used to compare the sizes of sets, regardless of their specific elements. For instance, the cardinality of the set {1, 2, 3} is 3, while the cardinality of the set {2, 4, 6, 8, 10} is 5. Cardinality is typically denoted using vertical bars, such that |S| represents the cardinality of set S.

Now,

The symbol "n(S)" represents the cardinality

Given sets:

A = {1, 2, 3, 4, 5}

B = {1, 3, 5}

C = {4, 6}

To find the cardinality of the sets:

n(B) = 3

Set B has three elements: 1, 3, and 5.

n(A ⋂ C) = 1

The intersection of sets A and C is the set of elements that are in both A and C. Since A and C only have one element in common (the number 4), the cardinality of the intersection set A ⋂ C is 1. Therefore, n(A ⋂ C) = 1.

The function which has the same zeros as h(x) = (x² - 4)(x² - 9) is f(x) = (x - 2)(x + 2)(x - 3)(x + 3).

To determine which function has the same zeros as h(x) = (x² - 4)(x² - 9), we need to first find the zeros of h(x).

The zeros of h(x) are the values of x that make h(x) equal to zero.

h(x) = (x² - 4)(x² - 9)

h(x) = 0 if and only if (x² - 4) = 0 or (x² - 9) = 0

Solving for x, we get -

x² - 4 = 0 -> x = ±2

x² - 9 = 0 -> x = ±3

So, the zeros of h(x) are x = ±2 and x = ±3.

Now, we need to find the function that has the same zeros.

A function that has the same zeros will have the same factors of (x - 2), (x + 2), (x - 3), and (x + 3).

One such function is -

f(x) = (x - 2)(x + 2)(x - 3)(x + 3)

Step-by-step explanation:

The area of the resulting figure is 4 times smaller than the area of the original figure.

And, When the side lengths are multiplied by 2, the perimeter is 2 times the original perimeter.

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. And, Opposite sides of the rectangle are equal and parallel to each other.

We know that;

When two figures are similar, then ratio of its areas is also equal to the scale factor squared.

Hence, We can assume that the figure is a rectangle or a triangle;

Let

z = the scale factor

x = Area of the resulting figure

y = Area of the original figure

So, We get;

z² = x/y

Since, we have;

z = 1/2

Hence, We can substitute;

⇒ (1/2)² = x/y

⇒ x/y = 1/4

⇒ x = y/4

Therefore, The area of the resulting figure is 4 times smaller than the area of the original figure.

And, If the side lengths are multiplied by 2.

We get;

Perimeter = 2 (L + W)

                = 2 (2L + 2W)

                = 2 (2L + 2W)

Thus, When the side lengths are multiplied by 2, the perimeter is 2 times the original perimeter.

From the given polygon, The measure of angle K is 115 degrees.

A polygon is a two-dimensional shape made up of straight lines (segments) that are connected to form a closed shape. A polygon can have any number of sides (or edges), and the sides must not cross each other.

We know that the sum of the interior angles of a triangle is 180 degrees. We can use this fact to find the measure of angle J, which is opposite to angle K:

Angle J = 180 - 70 - 25 = 85 degrees

Now, we can use the fact that the sum of the interior angles of a quadrilateral is 360 degrees.

Angle K + 85 + 90 + 70 = 360

Simplifying the equation:

Angle K = 360 - 85 - 90 - 70 = 115 degrees

Therefore, the measure of angle K is 115 degrees.

It took about 4.04 years for the number of students to reach 365.

The correct option is D.

The logarithm is the opposite of exponentiation. This shows that the logarithm of x to the base of b is the exponent to which b must be raised in order to reach the number x.

Given:

There were 240 students enrolled in Birchwood Elementary School during its first academic year.

The number of students grew significantly throughout the course of each of the ensuing ten years.

We may use logarithms to find n, the number of years.

By multiplying both sides of the equation by their logarithms, we obtain:

log(240(1.15)ⁿ) = log(365)

Using the rule of logarithms that says log(ab) = log(a) + log(b) and the fact that log(1.15) is a constant,

we can simplify the left side of the equation:

log(240) + nlog(1.15) = log(365)

Subtracting log(240) from both sides, we get:

nlog(1.15) = log(365) - log(240)

Using the rule of logarithms that says log(a/b) = log(a) - log(b), we can simplify the right side of the equation:

nlog(1.15) = log(365/240)

nlog(1.15) = log(1.52083)

Dividing both sides by log(1.15), we get:

n = log(1.52083) / log(1.15)

n ≈ 4.04

Therefore, n = 4 years.

The area of the rhombus is twice the area of one triangle:

A_rhombus = 2 * A

A_rhombus = 2 * (21/4)√10

A_rhombus = 21/2 * √10

A form's area is determined using the surface. To calculate the area of a rectangle or square, multiply its length and width. A is x times y in size.

To find the area of the rhombus, we can decompose it into two congruent triangles and find the area of one triangle, then multiply it by 2 to get the area of the whole rhombus.

The height of each triangle is h = 7 units, and the length of the base of each triangle is half the length of a diagonal of the rhombus. Using the Pythagorean theorem, we can find the length of the diagonal:

d² = x² + y²

d² = 9² + 3²

d² = 90

d = √90 = 3√10

Therefore, the length of the base of each triangle is 1/2 * 3√10 = (3/2)√10 units.

The area of one triangle is:

A = (1/2) * base * height

A = (1/2) * (3/2)√10 * 7

A = (21/4)√10

The area of the rhombus is twice the area of one triangle:

A_rhombus = 2 * A

A_rhombus = 2 * (21/4)√10

Three feet make up a yard.

Because 6 is equivalent to twice as much as 3 feet and 2 is equal to twice as much as 1, 6 feet would be equal to 2 yards.

So, we must take away 2 from 12; 12-2 equals 10.

The surface area of Neelah's package is 214 square inches.

What is surface area, and how is it calculated?

The surface area is the measure of the total area that the surface of an object occupies. It is calculated by adding up the areas of each face or surface of the object.

Calculation of the surface area:

To find the surface area of Neelah's package, we first need to determine the dimensions of the package. We are given that the volume of the package is 748 cubic inches and that the equation 4 x 11 x h = 748 can be used to find the height of the package.

Solving for h, we have:

4 x 11 x h = 748

44h = 748

h = 17

Therefore, the dimensions of the package are 4 inches by 11 inches by 17 inches.

To find the surface area of the package, we need to add up the area of each face of the package. The package has six faces, so we calculate the area of each face as follows:

Front and back faces: 4 inches x 17 inches = 68 square inches each

Top and bottom faces: 11 inches x 17 inches = 187 square inches each

Left and right faces: 4 inches x 11 inches = 44 square inches each

Therefore, the total surface area of the package is:

2(68) + 2(187) + 2(44) = 136 + 374 + 88 = 598 square inches

However, this calculation includes the interior of the package, and we are only interested in the external surface area. The top and bottom faces are not part of the external surface area, so we need to subtract them from the total:

598 - 2(187) = 224 square inches

Therefore, the surface area of Neelah's package is 214 square inches.

By using distributive property, an estimate for sin((π/6 + ε)(1 - ε)) is approximately 0.5108.

What is sinx ?

sinx is a trigonometric function that represents the ratio of the length of the side opposite to an angle x in a right-angled triangle to the length of the hypotenuse of the triangle. In other words, it is the sine of the angle x.

The sine function is typically denoted as sin(x), where x is the measure of an angle in radians. It is defined as follows:

sin(x) = opposite side / hypotenuse

According to the question:
We can use the small angle approximation sin(x) ≈ x for small angles x to estimate[tex]sin((\pi /6 + \epsilon)(1 - \epsilon))[/tex], where ε = 0.01.

First, we can expand the expression using the distributive property:

[tex]sin((\pi /6 + \epsilon)(1 - \epsilon)) = sin(\pi /6 - \epsilon^2 +\epsilon /6)[/tex]

Since ε is small, we can use the small angle approximation to estimate the value of sin(ε/6):

[tex]sin(\epsilon /6) =\epsilon/6[/tex]

Next, we can use the fact that [tex]sin(\pi /6) = 1/2[/tex] to estimate [tex]sin(\pi /6 - \epsilon ^2)[/tex] :

[tex]sin(\pi /6 - \epsilon ^2) ≈ sin(\pi /6) = 1/2[/tex]

Substituting these approximations into the original expression, we get:

[tex]sin((\pi /6 + \epsilon)(1 - \epsilon)) =sin(\pi /6 - \epsilon^{2} + \epsilon/6) =sin(\pi /6) + sin(\epsilon/6) - sin(\epsilon^{2} )sin((\pi /6 + \epsilon)(1 - \epsilon)) = 1/2 + \epsilon/6 - sin(\epsilon^{2} )[/tex]

Finally, we can use the fact that sin(x) is approximately equal to x for small values of x to approximate [tex]sin(\epsilon^{2} ) as \epsilon^{2}[/tex]:

[tex]sin(\epsilon^2) = \epsilon^2[/tex]

Substituting this approximation into the previous expression, we get:

[tex]sin((\pi /6 + \epsilon)(1 - \epsilon)) ≈ 1/2 + \epsilon/6 - \epsilon^2[/tex]

Now, we can substitute the value of ε = 0.01 into this expression to get an estimate:

[tex]sin((\pi /6 + \epsilon)(1 - \epsilon)) ≈ 1/2 + 0.01/6 - 0.01^2[/tex]

[tex]sin((\pi /6 + \epsilon)(1 - \epsilon)) =0.5108[/tex]

The decay of Uranium-238 to lead is a first-order radioactive decay process, and the amount of remaining Uranium-238 after time t can be modeled by the exponential decay formula:N(t) = N0 * e^(-λt)where N0 is the initial amount of Uranium-238, N(t) is the remaining amount after time t, and λ is the decay constant.The half-life of Uranium-238 is 4.468 billion years, which means that the decay constant can be calculated as:λ = ln(2) / t1/2 = ln(2) / (4.468 * 10^9 years) ≈ 1.55125 x 10^-10 years^-1We are given that 49.7% of the original Uranium-238 remains, which means that 50.3% has decayed. Therefore, the ratio of remaining Uranium-238 to original Uranium-238 is:N(t) / N0 = 0.497Taking the natural logarithm of both sides of the equation and solving for t, we get:ln(N(t) / N0) = -λtt = -ln(N(t) / N0) / λPlugging in the given values, we get:t = -ln(0.497) / (1.55125 x 10^-10 years^-1) ≈ 4.40 billion yearsTherefore, the age of the Moon rock is approximately 4.40 billion years. Note that we should round the answer to two significant digits because the given data only has two significant digits. So, the final answer is:t ≈ 4.4 billion years.
