The volume of Ganymede is approximately 3.48 times the volume of the Moon, based on the given diameters of the two moons and the formula for the volume of a sphere.

The volume of a sphere is the amount of space occupied by the sphere in three-dimensional space. It can be calculated using the formula V = (4/3)πr³, where V is the volume of the sphere, r is the radius of the sphere, and π (pi) is a mathematical constant approximately equal to 3.14159. This formula states that the volume of a sphere is four-thirds of the product of pi and the cube of the sphere's radius.

In the given question,

The volume of a sphere can be calculated using the formula V = (4/3)πr³, where r is the radius of the sphere. Since we are given the diameters of the two moons, we can calculate their radii by dividing the diameters by 2. Therefore, the radius of Ganymede is 3,388/2 = 1,694 km, and the radius of the Moon is 1,245/2 = 622.5 km.

Now, we can calculate the volumes of the two moons:

V_Ganymede = (4/3)π(1694)³ ≈ 7.66 x 10^10 km³

V_Moon = (4/3)π(622.5)³ ≈ 2.2 x 10^10 km³

To find how many times larger Ganymede's volume is compared to the Moon's volume, we can divide the volume of Ganymede by the volume of the Moon:

V_Ganymede / V_Moon ≈ (7.66 x 10¹⁰) / (2.2 x 10¹⁰) ≈ 3.48

Therefore, the volume of Ganymede is approximately 3.48 times the volume of the Moon.

Answer: y = 3.75x + 2.50

Step-by-step explanation:

The equation that can be used to find y, the total cost of renting a bike, if x represents the number of hours Violet rents the bike is:

y = 3.75x + 2.50

Explanation:

Violet pays an initial fee of $2.50, which is a fixed cost that does not depend on the number of hours she rents the bike. Additionally, she pays $3.75 per hour she rents the bike, which is a variable cost that depends on the number of hours. Therefore, the total cost of renting a bike (y) can be expressed as the sum of the fixed cost ($2.50) and the variable cost ($3.75x), which gives the equation:

The series can be represented in summation notation as follows: ∑(n = 7 to 207) (4n - 1)

In this notation, the Greek letter sigma (∑) represents the summation symbol, and n represents the index of summation. The series starts from n = 7 and goes up to n = 207, with each term being (4n - 1). The notation "n = 7 to 207" indicates the range of values that n takes on in the summation. The expression (4n - 1) represents the general term in the series, which changes as n varies from 7 to 207.

Summation notation, denoted by the Greek letter sigma (∑), is a shorthand way to represent the sum of a sequence of numbers. In this case, the series you provided is:

7 + 11 + 15 + … + 203 + 207

The general term of the series, which changes as "n" varies, is (4n - 1). This means that for each value of "n", we substitute it into the expression (4n - 1) to get the corresponding term in the series. For example, when "n" is 7, the corresponding term is (4 * 7 - 1) = 27. When "n" is 11, the corresponding term is (4 * 11 - 1) = 43, and so on, up to "n" = 207.

The summation notation "∑(n = 7 to 207) (4n - 1)" represents the sum of all the terms in the series, where "n" takes on values from 7 to 207, and the term for each "n" is (4n - 1). This notation allows us to compactly represent the entire series in a concise mathematical form.

Answer:

the amplíetude of the function is 1.5

Step-by-step explanation:

.

Every vector b in R3, the equation Ax = b has a solution if every row of A has a pivot.

The statement is true.

True.

If a reduced echelon matrix in R3 is obtained by row operations from a matrix A, then the reduced echelon matrix is in row echelon form and is equivalent to the original matrix A.

If every row of A has a pivot, then every row has a leading non-zero entry in the row echelon form of A.

This means that each row of the row echelon form of A has a pivot, and so the matrix has full row rank.

The number of pivot columns in the reduced echelon matrix equals the row rank of A, which is also the same as the column rank of A.

Vector b in R3, the equation Ax = b has a solution if and only if b is a linear combination of the columns of A.

If A has full column rank, then the columns of A span the column space of A, which means that any vector in the column space can be expressed as a linear combination of the columns of A.

If every row of A has a pivot, then A has full row rank, full column rank, and the columns of A span R3.

Answer:

Equation for Angle 3- 90-38=52

Angle 3= 52

Angle 5= 38

Angle 6= 52

Step-by-step explanation:

Angle is 90 degrees.

Angle 2 is 38 degrees.

If you are just looking at the bottom half(Angle 6, Angle 1, and Angle 2) They are all supposed to add up to equal 180 degrees because it is a supplementary angle.

So you add 90 and 38 and it gives you 52(Angle 6).
90+38+52=180

Then a complementary angle is two angles that equal 90 degrees.

So if you take Angle 2(38 degrees) and subtract it from 90, you get 52. Which is Angle 3.

You do the same with Angle 6 and Angle 5.

Angle 6(52 degrees) subtract from 90 and you get 38.

Then you add 38 and 52 and you get 90.

Then 180-90=90, so Angle 4 is 90 degrees.

The function f has a relative maximum at x = -√[(2 + sqrt(2))/5], so the answer is (b) - root 5/5.

To find the relative maximum of a function, we need to find the critical points of the function, where the derivative of the function is zero or undefined.

Let's start by finding the derivative of f(x)

f'(x) = 15x⁴ - 12x² - 3

Now, we can find the critical points by solving the equation f'(x) = 0

15x⁴ - 12x² - 3 = 0

We can factor this equation by substituting y = x²

15y² - 12y - 3 = 0

Solving for y, we get

y = (2 ± √(2))/5

Substituting back x² for y, we get

x² = (2 ± √(2))/5

Taking the square root of both sides, we get

x = ± √[(2 ± √(2))/5]

Therefore, the critical points are

x = -√[(2 + √(2))/5], √[(2 - √(2))/5]

Now, we need to determine whether these critical points are relative maximum or minimum.

We can use the second derivative test to determine the nature of the critical points. The second derivative of f(x) is

f''(x) = 60x³ - 24x

Plugging in the critical points, we get

f''(-√[(2 + √(2))/5]) = -48√(2) < 0 (relative maximum)

f''(√[(2 - √(2))/5]) = 48√(2) > 0 (relative minimum)

Therefore, the relative maximum of the function f(x) is at

x = -√[(2 + √(2))/5]

So, the correct answer is (b) - root 5/5.

The Laplace transform of the given function f(t) = {0, 0 < t < 1, t², t ≥ 1} is 2s⁻³.

Given the function f(t) = {0, 0 < t < 1, t², t ≥ 1}, we need to find its Laplace transform. The Laplace transform of a function f(t) is denoted by F(s) and is defined as follows:

F(s) = L{f(t)} = ∫[0,∞) f(t)e⁻ᵃˣdt,

where s is a complex variable.

To find the Laplace transform of the given function, we need to split the function into two parts: one for 0 < t < 1 and another for t ≥ 1. For 0 < t < 1, f(t) = 0, so the integral becomes:

L{0} = ∫ 0e⁻ᵃˣdt = 0.

For t ≥ 1, f(t) = t², so the integral becomes:

L{t²} = ∫ t²e⁻ᵃˣdt.

To evaluate this integral, we can use integration by parts. Let u = t² and dv = e⁻ᵃˣdt, then du/dt = 2t and v = (-1/s) e⁻ᵃˣ. Using the integration by parts formula, we get:

L{t²} = ∫ t²e⁻ᵃˣdt = (-t²/s)e⁻ᵃˣ∣∣∣[0,∞) + (2/s)∫[0,∞) te⁻ᵃˣdt.

The first term in the above equation evaluates to zero because e⁻ᵃˣapproaches zero as t approaches infinity. Using integration by parts again for the second term, we get:

L{t²} = (-t²/s)e⁻ᵃˣ∣∣∣[0,∞) + (2/s)(-t/s)e⁻ᵃˣ∣∣∣[0,∞) + (2/s²)∫[0,∞) e⁻ᵃˣdt.

The first two terms in the above equation evaluate to zero for the same reason as before. The integral in the last term evaluates to (1/s²), so we get:

L{t²} = 2/s³.

Therefore, the Laplace transform of the given function f(t) is:

L{f(t)} = L{0} + L{t²} = 0 + 2/s³ = 2s⁻³.
