The solution to the inequality is all values of x less than 5. We can write the solution set using interval notation as (-∞, 5).

To solve the inequality -5x - 3 + 2x > -18, we need to isolate the variable x on one side of the inequality sign.

Starting with the given inequality:

-5x - 3 + 2x > -18

Simplifying the left-hand side by combining the like terms:

-3x - 3 > -18

Adding 3 to both sides:

-3x > -15

Dividing both sides by -3, and reversing the inequality sign since we are dividing by a negative number:

x < 5

Therefore, the solution to the inequality is all values of x less than 5. We can write the solution set using interval notation as (-∞, 5).

Finally, we can divide both sides of the equation by -120/r to get r = -120/(t - 120).

Therefore, the inverse of Janine's equation is r = -120/(t - 120).

In algebra, an equation is a mathematical statement that establishes the equality of two mathematical expressions. Take a look at the formula 3x + 5 = 14, where 3x + 5 and 14 are two expressions that are separated by the word "equal."

Either identities or conditional equations are categories for equations. For each potential value, the variables provide an identity. Only certain combinations of the values for the variables allow a conditional equation to hold true. Two expressions are joined together in an equation by the equals sign ("=").

To find the inverse of Janine's equation, we need to solve for r in terms of t. Here is how we can do that:

First, we can rearrange the equation to get t - 120 = 1/r.

Then, we can divide both sides of the equation by 1/r to get t/r - 120/r = 1.

Finally, we can divide both sides of the equation by -120/r to get r = -120/(t - 120).

Therefore, the inverse of Janine's equation is r = -120/(t - 120).

The value of sin(7π/8) is 0.7071. This value can also be expressed as √2/2 or 1/√2.

When evaluating the function sin(7π/8), we will use the unit circle method and determine the value of sine at 7π/8 radians.The unit circle method is one way to figure out the value of the sine of an angle in radians. This method involves visualizing a circle of radius 1 unit that is centered at the origin of a Cartesian coordinate plane. In this unit circle, we can draw a ray originating from the center of the circle and passing through an angle θ on the terminal side.

The x-coordinate of the point of intersection of this ray and the unit circle is cos(θ), and the y-coordinate is sin(θ).First, we find the angle 7π/8 on the unit circle. As 7π/8 is an angle in the second quadrant, we will draw a circle of radius 1 unit centered at the origin of a coordinate plane and we will count the angles from the x-axis in a counterclockwise direction until we reach 7π/8 radians.

We will place a dot on the unit circle where the angle terminates.Then, we can drop a perpendicular line from the point of intersection of the ray with the unit circle to the x-axis to form a right triangle. This right triangle has hypotenuse 1 and adjacent side cos(7π/8).

By the Pythagorean theorem, the opposite side is sqrt(1 - cos²(7π/8)).Hence, the value of sin(7π/8) is:sin(7π/8) = opposite/hypotenuse= sqrt(1 - cos²(7π/8))/1Now, we can use the trigonometric identity sin²(x) + cos²(x) = 1 to find the value of cos²(7π/8):cos²(7π/8) = 1 - sin²(7π/8)

We know that sin(π/8) = sin(π/8), so we can use the double-angle identity sin(2θ) = 2sin(θ)cos(θ) to find the value of sin(π/4) = sin(2(π/8)):sin(π/4) = 2sin(π/8)cos(π/8)Now, we can use the Pythagorean identity sin²(x) + cos²(x) = 1 to find the value of cos(π/8):cos(π/8) = sqrt(1 - sin²(π/8))

Finally, we can use the double-angle identity cos(2θ) = cos²(θ) - sin²(θ) to find the value of cos(π/4) = cos(2(π/8)):cos(π/4) = cos²(π/8) - sin²(π/8)= (1 - sin²(π/8)) - sin²(π/8)= 1 - 2sin²(π/8)Therefore, the value of sin(7π/8) is:sin(7π/8) = sqrt(1 - cos²(7π/8))/1= sqrt(1 - (1 - 2sin²(π/8)))/1= sqrt(2sin²(π/8))/1= sqrt(2)/2= 0.7071 (rounded to four decimal places)

Therefore, the value of sin(7π/8) is 0.7071. This value can also be expressed as √2/2 or 1/√2.

We have two right-angled triangles that share a common side, with side lengths 6 and 10. Let's label the sides of the triangles as follows:

Triangle 1:

Side adjacent to the right angle: 6 (let's call it 'a')

Side opposite to the right angle: x (let's call it 'b')

Triangle 2:

Side adjacent to the right angle: x (let's call it 'c')

Side opposite to the right angle: 10 (let's call it 'd')

Using the Pythagorean theorem, we can write the following equations for each triangle:

Triangle 1:\(a^2 + b^2 = 6^2\)

Triangle 2: \(c^2 + d^2 = 10^2\)

Since the triangles share a common side, we know that b = c. Therefore, we can rewrite the equations as:

\(a^2 + b^2 = 6^2\\b^2 + d^2 = 10^2\)

Substituting b = c, we get:

\(a^2 + c^2 = 6^2\\c^2 + d^2 = 10^2\)

Now, let's add these two equations together:

\(a^2 + c^2 + c^2 + d^2 = 6^2 + 10^2\\a^2 + 2c^2 + d^2 = 36 + 100\\a^2 + 2c^2 + d^2 = 136\)

Since a^2 + 2c^2 + d^2 is equal to 136, we can conclude that x (b or c) is between 11 and 12

\(\frac{3}{4}\)

Step-by-step explanation:

\(\frac{3}{5} = \frac{36}{x}\)

3x = 36 x 5

3x = 180

x = 60

Michael has 60 marbles.

Nick recieves 9 more marbles so he has 36 + 9 = 45 marbles

The new ratio will be:

\(\frac{45}{60}\)  = \(\frac{3}{4}\)

To change to spherical coordinates, we can use the following formula:

x = ρ sin φ cos θ

y = ρ sin φ sin θ

z = ρ cos φ

We also note that the region of integration is a hemisphere with radius 3, and that the integrand contains x^2z+y^2z+z^3. Since we are integrating over a hemisphere, the bounds of ρ can be from 0 to 3, φ can be from 0 to π/2, and θ can be from 0 to 2π.

Next, we need to express the integrand in terms of ρ, φ, and θ. Substituting x, y, and z, we get:

x^2z + y^2z + z^3 = ρ^4 sin^2 φ cos^2 θ (ρ cos φ) + ρ^4 sin^2 φ sin^2 θ (ρ cos φ) + (ρ cos φ)^3

Simplifying, we get:

x^2z + y^2z + z^3 = ρ^5 cos^2 φ + ρ^3 cos^3 φ

Thus, the new integral is:

∫0^(2π) ∫0^(π/2) ∫0^3 (ρ^5 cos^2 φ + ρ^3 cos^3 φ) ρ^2 sin φ dρ dφ dθ

Integrating with respect to ρ, we get:

∫0^(2π) ∫0^(π/2) [ 1/6 ρ^6 cos^2 φ + 1/4 ρ^4 cos^3 φ ]_|ρ=0^3 sin φ dφ dθ

Simplifying and integrating with respect to φ, we get:

∫0^(2π) [ 9/5 sin^5 φ - 27/14 sin^7 φ ]_|φ=0^(π/2) dθ

Evaluating the limits, we get:

∫0^(2π) [ 9/5 - 27/14 ] dθ

Finally, evaluating the integral, we get:

∫0^(2π) [ 33/35 ] dθ = 66π/35

Therefore, the value of the integral after changing to spherical coordinates is 66π/35.

Y intercept is the Y value when x is equal to 0. In the point (0,1) x is 0 and y is 1, so the y-intercept is 1.Slope is-1/4.

When a line crosses the y-axis on a graph, that location is known as the y-intercept.It is always 0 for the associated x-coordinate.

By calculating rise over run, the slope can be determined.This is accomplished by splitting the discrepancies between the y- and x-coordinates. The values of the y-intercept and slope reveal details on the nature of the relationship between the two variables, x and y.

The slope is the change in Y over the change in x:

Slope = (0-1) / 4-0) = -1/4

Slope = -1/4

Y intercept is the Y value when x is equal to 0. In the point (0,1) x is 0 and y is 1, so the y-intercept is 1.
