The values that, the function intersect the x axis at 2 different points is -4 < b < 4. So correct option is D.

A function in mathematics is a relationship between a set of inputs (also known as independent variables or arguments) and a set of outputs (also known as dependent variables or values). The output of a function is determined by the inputs, and the function assigns exactly one output value to each input value.

A function can be represented in many ways, including a formula, a table, or a graph. The formula of a function defines the relationship between the inputs and outputs, and can be used to calculate the output for a given input. A table lists input and output values, and a graph represents the function by plotting the input and output values.

Functions are a fundamental concept in mathematics and are used in many areas, including algebra, calculus, and other branches of mathematics, as well as in science, engineering, and other fields. Functions can be simple, such as linear functions, or complex, such as exponential functions or trigonometric functions.

For the function f(x) = x^2 + bx + 4 to intersect the z-axis at two different points, it must have two real roots. This means that the discriminant of the quadratic equation must be greater than 0. The discriminant of the quadratic equation is given by b^2 - 4(1)(4). Hence, b^2 - 16 > 0, or b^2 > 16, which simplifies to -4 < b < 4.

Therefore, the answer is D: -4 < b < 4.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Slope= 501.60-349.60/33-23

=152/10

=15.2

Now let us find the y intercept

228=15.2(15)+b

228=228+b

b=0

Now let us find how much he earns in 15.5 hours.

Probability theory, a subfield of mathematics, gauges the likelihood of an occurrence or a claim being true. An event's probability is a number between 0 and 1, where approximately 0 indicates how unlikely the event is to occur and 1 indicates certainty. A probability is a numerical representation of the likelihood or likelihood that a particular event will occur.

Answer:

Yolanda served 13 times , Kareem served 38 times and Jose served 19 times.

Step-by-step explanation:

No of orders served by Yolanda = x

No of orders served by Kareem = y

No of orders served by Jose = z

x + y + z = 82  ------------- (1)

y = 2z  ------------ (2)

x = z - 6  ---------(3)

substituting (2) and (3) in (1) :-

z - 6 + 2z + z = 82

4z - 6 = 82

4z = 76

z = 19

y = 2(19)

y = 38

x = 19 - 6

x = 13

The equation of the circle that has a diameter with endpoints located at (5, –3) and (11, 5) is;   (x – 8)² + (y – 1)² = 25

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

here, we have,

The midpoint of the diameter of a circle is it's center.

As such; the coordinates of its center are;

x = (5+11)/2

x = 8

y = (-3 + 5)/2

y = 1

The coordinates of the center are then; (8, 1)

The radius of a circle is half the length of the diameter;

Radius, r = d/2

where; d = √(11-5)² + (5-(-3))²

d = √36 + 64

d = √100

d = 10

Therefore, radius, r = 10/2 = 5.

Therefore, the equation of the circle usually takes the form;

(x -f)² + (x -g)² = r²

(x – 8)² + (y – 1)² = 25.

According to the question, the solution to the equation is x = -7.

The equation is a representation of a mathematical relation between two or more variables. It is usually expressed as an equation, where one side of the equation is equal to the other. For example, the equation y=mx+b is a linear equation with two variables, m and b, which are known as the slope and the y-intercept, respectively.

To solve this equation, we must first combine like terms on both sides of the equals sign.

-3x + 3 - x + 10 = -3x + 6

Next, we can subtract 3 from both sides of the equation to isolate the x-term.

-4x + 13 = -3x + 6

Finally, we can subtract -3x from both sides of the equation to isolate the constant term.

-7x = 7

We can then divide both sides of the equation by -7 to solve for x.

x = -7

Therefore, the solution to the equation is x = -7.

Answer:

The equation of a circle can be represented in the form (x-h)^2 + (y-k)^2 = r^2, where (h,k) is the center of the circle and r is the radius.

A diameter of a circle is a straight line passing through the center of the circle and has endpoints on the circle.

Given that the equation of the diameter of a circle is x+y-14=0 and 2x-y-4=0, we can find the center of the circle by solving for the intersection of these two lines.

We can find the intersection point of these lines by solving the system of equations using the substitution method:

x+y-14=0 and 2x-y-4=0

x = 14/3, y = 10/3

So the center of the circle is (14/3, 10/3)

Since we know that the point (3,4) lies on the circle, we can use the distance formula to find the radius of the circle.

r = sqrt((x-h)^2 + (y-k)^2)

r = sqrt((3-(14/3))^2 + (4-(10/3))^2) = sqrt(5)

Therefore, the equation of the circle is (x-14/3)^2 + (y-10/3)^2 = 5^2

or (x-14/3)^2 + (y-10/3)^2 = 25

So, the equation of the circle passing through point (3,4) and having equation of its diameter x+y-14=0 and 2x-y-4=0 is (x-14/3)^2 + (y-10/3)^2 = 25

Answer:

Step-by-step explanation:

You want the measures of 5 marked angles in the figure showing two transversals crossing parallel lines.

Angle 1 forms a linear pair with the angle marked 88°, so is supplementary to it.

  Angle 1 = 180° -88°

  Angle 1 = 92°

Angle 3 is a corresponding angle to the one marked 64° where the horizontal transversal crosses the parallel lines. Corresponding angles are congruent.

  Angle 3 = 64°

Angles 2 and 3 are "remote interior angles" with respect to the exterior angle marked 88°. Hence their sum is 88°.

  Angle 2 = 88° -Angle 3 = 88° -64°

  Angle 2 = 24°

Angles 3, 4, and 81° combine to form a straight angle of 180°.

  Angle 4 = 180° -64° -81°

  Angle 4 = 35°

Angle 5 is an alternate interior angle with respect to the one marked 81° where the downward-sloping transversal crosses the parallel lines. Alternate interior angles are congruent.

  Angle 5 = 81°

The correct solution for the area of this triangle is 20 inches².

The area of a triangle is a measure of the amount of two-dimensional space enclosed by its three sides. It is represented by the symbol A and is calculated by multiplying the base of the triangle by its height and dividing the result by 2.

A = (1/2)b×h

In other words, the height of the triangle is a line segment perpendicular to the base that divides the triangle into two smaller triangles of equal area. The area of a triangle is important in many real-world applications, such as in construction and architecture, where it is used to determine the amount of material needed for a project, and in geometry, where it is used to solve problems related to triangles.

No, Kevin's solution is not correct. The formula for the area of a triangle is

The equation of the linear function represented by the table in slope intercept form is f(x) = 2x + 2.

A linear function can be defined as the function whose graph is a straight line. It can also be defined as the function with one or more variables and the exponent of the variable is 1.

Equation of the linear function in slope intercept form can be represented as y = mx + d, where m is the slope and d is the y intercept.

Slope is the change in y coordinates divided by the change in x coordinates.

y intercept is the point on the line where the line touches the Y axis.

Given points are (-2, -2), (2, 6), (6, 14) and (10, 22).

Consider the points (-2, -2) and (2, 6).

Slope, m = (6 - -2) / (2 - -2) = 8 / 4 = 2

So the equation becomes y = 2x + d

Substituting one of the points (2, 6) in the above equation,

6 = (2 × 2) + d

d = 2

So the equation is y = 2x + 2.

Hence the given linear function can be represented as f(x) = 2x + 2.

Step-by-step explanation: You multiply 3*750, then multiply the product by 0.12 because 0.12 = 12%.

Let the width be [tex]w[/tex] inches and the length be [tex]w+15[/tex] inches.

So, the dimensions of the box are [tex]w-6[/tex], [tex]w+9[/tex], and [tex]3[/tex] inches.

[tex]3(w-6)(w+9)=1350 \\ \\ (w-6)(w+9)=450 \\ \\ w^2+3w-54=450 \\ \\ w^2+3w-504=0 \\ \\ (w+24)(w-21)=0 \\ \\ w=-24,21[/tex]

Rejecting the negative case, [tex]w=21[/tex].

So, the dimensions are 21 by 36 inches.
