The y-intercept of the equation is -10.

Equation is a mathematical statement that expresses the equality of two expressions, which are separated by an equals sign. It can be used to represent a variety of different relationships, such as equality, inequality, addition, subtraction, multiplication, and division. Equations can be used to solve a variety of problems in science, engineering, and mathematics.

The x-intercepts of the graph of the equation r(x) are those values of x for which the equation is equal to 0. To find the x-intercepts, we must solve the equation:

x²+ 3x - 10 = 0

Factoring the equation, we get:

(x+5)(x-3)(x+1) = 0

The solutions of this equation are x = -5, -1, and 3. Therefore, the x-intercepts of the equation are -5, -1, and 3.

To find the y-intercept, we must plug 0 in for x in the equation:

y = x² + 3x - 10/ (x+1)(x-3)(x+5)

When x = 0, we get:

y = -10/ (0+1)(0-3)(0+5)

Therefore, the y-intercept of the equation is -10.

The vertical asymptote of the equation is the line x = -1, since it is the only value of x that makes the denominator equal to 0.

Answer:

(2, -2)

Step-by-step explanation:

To rotate a point in a coordinate plane 90 degrees clockwise, we need to switch the x and y coordinates and negate the new x coordinate.

So let's apply this formula to the point (-2, -2):

- The new x-coordinate will be the original y-coordinate: -2

- The new y-coordinate will be the negation of the original x-coordinate: -(-2) = 2

Therefore, after rotating (-2, -2) 90 degrees clockwise, we get the point (2, -2).

We can visualize this by plotting both points on a coordinate plane and drawing a line of reflection that represents the rotation:

Answer:

x = 8

Step-by-step explanation:

Let x be the number of blue seats in each section.

Then the total number of seats in each section is:

14 + x

Since there are 4 identical sections, the total number of seats in the theater is:

4(14 + x) = 56 + 4x

We know that the theater has 88 seats, so:

56 + 4x = 88

Simplifying the equation:

4x = 32

x = 8

Therefore, each section has 14 red seats and 8 blue seats.

The expression for the number of blue seats in each section is x = 8.

The width of the rectangular tile is obtained to be 11 and 2/3 cm.

What is a rectangle?

A quadrilateral with parallel sides that are equivalent to one another and four equal vertices is known as a rectangle. It is also known as an equiangular rectangle for this reason.

The bathroom tile is in a rectangular shape.

Let's call the width of the tile "w".

From the problem, we know that -

w = (2 and 1/3) × h

We also know that the height of the tile is 5 cm.

Substituting this value in the equation above, we get -

w = (2 and 1/3) × 5 cm

w = 7/3 × 5 cm

w = 35/3 cm

The formula to calculate the circumference of a circle is:

Circumference = 2πr

where "r" is the radius of the circle and "π" is the mathematical constant pi, approximately equal to 3.14159.

Given that the circumference of the circle is 20 ft, we can plug in the values into the formula and solve for "r":

20 = 2πr

Divide both sides of the equation by 2π:

r = 20 / (2π)

Simplify the expression by using the approximation of π as 3.14159:

r = 20 / (2 x 3.14159)

r = 3.1831 ft (rounded to four decimal places)

Therefore, the radius of the circle is approximately 3.1831 feet.

Answer:

22 degree

Step-by-step explanation:

We know

∠1 and ∠2 combined must be 90 degrees. We know angle 2 is 68 degrees.

What is the measure of angle 1?

90 - 68 = 22 degrees

So, angle 1 is 22 degrees.

The rules that are functions on an appropriate domain are A and D, and other solutions are shown below

Given that

g(x) = 4x² + x + 7

For g(-2), we substitute -2 for x in g(x) = 4x² + x + 7

So, we have

g(-2) = 4(-2)² + (-2) + 7

Evaluate

g(-2) = 21

Here, we have

A(t) = 3- 2t² + 4^t.

To calculate A(2) - A(1), we calculate A(2) and A(1) and then subtract the values

So, we have

A(2) = 3 - 2(2)² + 4² = 11

A(1) = 3 - 2(1)² + 4¹ = 5

So, we have

A(2) - A(1) = 11 - 5

A(2) - A(1) = 6

Here, we have

g(x) = 3(x - 6)² + 1

The vertex above is

vertex = (6, 1)

Because the leading coefficient (a) is greater than 0

i.e. a = 3, then the vertex is a minimum

So, the range is y ≥ 1

Here, we have the following definition

a ♡ b = (a + b)/2.

This means that

(5 ♡ 7) ♡ 11 = (5 + 7)/2 ♡ 11

(5 ♡ 7) ♡ 11 = 6 ♡ 11

So, we have

(5 ♡ 7) ♡ 11 = (6 + 11)/2

(5 ♡ 7) ♡ 11 = 8.5

To factor completely using the GCMF (Greatest Common Monomial Factor), we first need to identify the common monomial factor of all three terms. In this case, the common monomial factor is 2x²:

10x^5 + 8x^4 - 4x² = 2x²(5x^3 + 4x^2 - 2)

Now, we can see that the expression can be factored further, but it cannot be factored using the GCMF. However, we can use other factoring techniques, such as grouping or factoring by grouping, to factor the remaining expression:

2x²(5x^3 + 4x^2 - 2) = 2x²(5x^3 + 10x^2 - 6x^2 - 2)

= 2x²(5x^2(x + 2) - 2(x + 2))

= 2x²(5x^2 - 2)(x + 2)

The answer of the given question based on the  number best describes a typical rating in the contest the answer is 7.9.

The median is  measure of central tendency in statistics that represents  middle value of  dataset. It is  value that separates  highest 50% of  values from the lowest 50%.

To find  median of a dataset, you first need to sort  data in ascending or descending order.

The median rating is 7.9, which means that half of the contestants scored above 7.9 and half scored below. This suggests that 7.9 is a representative value of the ratings overall.

Additionally, the interquartile range (IQR) is a measure of the spread of the middle 50% of the ratings, and it is given as 0.8. This means that the ratings between the 25th and 75th percentile fall within a range of 0.8, which suggests that the ratings are fairly tightly clustered around the median of 7.9.

To write Z in Euler form, we first need to find its magnitude and argument.

The magnitude of Z is given by:

|Z| = √(Re(Z)^2 + Im(Z)^2)

where Re(Z) is the real part of Z, and Im(Z) is the imaginary part of Z.

In this case:

Im(Z) = √3 i

So:

|Z| = √(√3^2 + (√3)^2) = √(3 + 3) = √6

The argument of Z is given by:

arg(Z) = tan^(-1)(Im(Z) / Re(Z))

In this case:

arg(Z) = tan^(-1)((√3) / √3) = tan^(-1)(1) = π/4
