The zeroes of the equation x² + 3x - 40 is -8 or 5.

A quadratic equation is a second-order polynomial equation in a single variable x ax²+bx+c=0. with a ≠ 0 .

It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem.

Given:

F(x) = x² + 3x - 40

Now, solving the quadratic Equation

x² + 3x - 40 = 0

x² + 8x - 5x - 40 = 0

x(x + 8) - 5(x + 8)=0

(x+8) (x-5)= 0

So, x+8 = 0 or x-5=0

x=-8 or x= 5

Hence, the zeroes are -8 and 5.

The slope of the line that goes through the points (0, 2) and (1, -1) is -3.

What is the slope of the line?

The slope of a line is a number that describes the steepness of a line and the direction it is heading. It is also known as the "rise over run" or the "rate of change" of a line. The slope of a line is typically represented by the letter "m" and is found using the formula:

slope = (y2 - y1) / (x2 - x1)

To find the slope of a line, you need two points on the line (x1, y1) and (x2, y2) and substitute their coordinates into the slope formula.

To find the slope of a line, we use the formula:

slope = (y2 - y1) / (x2 - x1)

In this case, we have two points: (0, 2) and (1, -1). To find the slope between these two points, we can substitute their coordinates into the slope formula:

slope = (-1 - 2) / (1 - 0)

slope = -3

Hence, the slope of the line that goes through the points (0, 2) and (1, -1) is -3.

Since the midsegment of each trapezoid is parallel to each base and is half, it has a GH value of 0.85.

Having at least one pair of parallel sides, a trapezoid is a quadrilateral in American and Canadian English. In the UK and other nations that speak English, it is referred as as the Trapezium. A trapezoid is a convex quadrilateral according to Euclidean geometry. Its parallel sides make up the trapezoid's base. The trapezoid, a convex quadrilateral, is defined by an identical pair of opposite sides that are parallel to one another. On paper, the two-dimensional trapezoid shape seems like a table. The term "quadrilateral" in Euclidean geometry refers to a polygon with four sides and four vertices.

Using substitution method to solve the system of linear equation, the number of children is 90 and adults is 93.

In mathematics, a system of linear equations is the collection of two or more linear equations that share the same variables. The maximum power of the variable in the linear equations in this situation is 1, making them first-order equations. A linear equation may have one, two, or three variables. We can therefore create linear equations with n variables.

To solve this problem, we have to define our variables and then write the equations.

Let;

x + y = 183 ...eq(i)

1.75x + 2.5y = 390 ...eq(ii)

solving both equations

From equation (i)

x + y = 183

x = 183 - y ...eq(iii)

Put equation (iii) into equation (ii)

1.75(183 - y) + 2.5y = 390

y = 93

Put y = 93 into equation (i)

x + 93 = 183

x = 90

The number of child is 90 and adult is 93

So on solving the provided question, we can say that  y= |x| makes a starlight line, this equation is a linear function.

Two distinct but related concepts are referred to as linear functions in mathematics. A polynomial function of degree 0 or 1 is a linear function in calculus and related subjects if its graph is a straight line. Any function that depicts a straight line on a coordinate plane is said to be linear. For instance, y = 3x - 2 is a linear function since it depicts a straight line on the coordinate plane. f(x) = 3x - 2 can be used to represent the function since f(x) can be linked to y.

The integral represents a graph of the signed area, and the geometry is calculated. The area is found to be 100 units².

A plane that is created when two perpendicular coordinate axes cross each other is known as a cartesian plane. Everywhere in the Cartesian plane, the functions define the boundaries of regions with regular geometrical patterns. The right triangle and other regular regions are good examples of how the area of a region may be computed using the geometry of the region.

The given function is [tex]\int\limits^{10}_{-10} {|x|} \, dx[/tex].  The function of this integrand is defined as f(x)=|x| with -10 ≤ x ≤ 10. Now, the graph is drawn for this function.

From the graph, we can tell the base and height of the two right-angle triangles are 10 units and 10 units. Then, the area is,

[tex]\begin{aligned}A&=2\left(\frac{1}{2}\times b\times h\right)\\&=2\times \frac{1}{2}\times 10 \times 10\\&=\mathrm{100\;{units}^2}\end{aligned}[/tex]

The area can also be calculated by solving the integrals,

[tex]\begin{aligned}\int\limits^{10}_{-10} {|x|} \, dx &=\int\limits^0_{-10} {-x} \, dx +\int\limits^{10}_0 {x} \, dx\\&=\left[\frac{x^2}{2}\right]^{0}_{-10} +\left[\frac{x^2}{2}\right]^{10}_{0}\\&=\frac{1}{2}(100+100)\\&=\mathrm{100\;units^2}\\\end{aligned}[/tex]

The tangent of an acute angle in a right triangle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.

The given linear relationship slope of the line is D) 6.

What is slope?

An indication of how steep a line is is its slope. When calculating slope mathematically, "rise over run" is used (change in y divided by change in x). The ratio of how much y grows as x grows by a certain amount is known as the slope of a line. A line's slope, or the amount by which y rises as x rises, indicates how steep a line is. The slope is constant (the same) along the line.

Here from given tables lets take any two points to find slope, then

[tex](x_1,y_1)=(0,-6) and (x_2,y_2)=(1,0)[/tex]

Now using slope formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] then

=> m = [tex]\frac{0-(-6)}{1-0}[/tex]

=> m =[tex]\frac{6}{1}[/tex]

=> m = 6.

Hence the slope of the given table is D)6.

The probability of getting a household income of $75,000 in Maryland is 0.3989.

The normal distribution formula is given by:

P(x) = 1/√(2πσ^2) * e^[-(x-μ)^2 / (2σ^2)]

Where,

P(x) - Probability of getting a household income of x

μ - Mean annual household income in Maryland

σ - Standard deviation of annual household income in Maryland

Assuming that the mean annual household income in Maryland is $75,000 and the standard deviation is $10,000, the probability of getting a household income of $75,000 can be calculated using the formula given above.

P(75000) = 1/√(2π10000^2) * e^[-(75000-75000)^2 / (2*10000^2)]

Variation is a relation between a set of values of one variable and a set of values of other variables

If the value Q of a material is directly proportional to the square of its weight W. We can write:

Q α W²

Q = kW²   (where k is constant of proportionality)

If a material weighing 20 kg is worth 500, we have:

Q = kW²

500 = k × 20²

500 = 400k

k = 500/400

k = 5/4

k = 1.25

(a)the value of a material weighing 5 kg

Q = kW²

Q = 1.25 × 5² = 31.25

Before I solve the system, I am going to rewrite it to make it easier for me to understand it.

[tex]y=(x-3)^2+1\\y=-3x+10[/tex]

Notice that f(x) and g(x) have been changed into y. The reason is because f(x) and g(x) are the same and stand for y, but we only use f and g to distinguish between the 2 equations. We can use equal values to solve.

[tex](x-3)^2+1=-3x+10[/tex]              [exponent]

[tex]x^2-6x+9+1=-3x+10[/tex]        [add both sides by 3x]

[tex]x^2-3x+10=10[/tex]                        [subtract both sides by 10]

[tex]x^2-3x=0[/tex]                                  [factor]

[tex]x(x-3)=0[/tex]

Notice that x=0 and x-3=0. This means the solutions are x=0 and x=3.

To find the actual full solution, we have to plug those points back into the original equations.

The equation of the line with a slope of 2/3 passing through (-4, 1) is y = (2/3)x + 11/3

An equation is an expression relating two or more numbers and variables.

The slope - intercept form of a linear equation is:

y = mx + b

Where m is the rate of change(slope) and b is the y intercept.

The equation of a line passing through (x₁, y₁) with a slope of m is given by:

y - y₁ = m(x - x₁)

The line has a slope of 2/3 and pass through point (-4, 1). Hence:

y - 1 = (2/3)(x - (-4))

y - 1 = (2/3)(x + 4)

y = (2/3)x + 11/3
