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 required answer is 100 units².

The number of flowers that can be planted in 1 hour is 6 flowers.

To solve equations or determine the value of a variable, cross multiplication is employed in mathematical operations. In this procedure, the numerator of one side is multiplied by the denominator of the other side.

Given that the time required to plant trees is:

3. 5 hours = 21 flowers

Convert 3.5 hours into minutes.

3 hours 60 = 180 minutes,

Additional half hour can be represented as: 1/2 hours 60 = 30 minutes.

Total hours is 180 + 30 = 210 minutes.

So it takes, 210 minutes to plant 21 flowers.

The time taken to plant flowers in 60 minutes is:

Step-by-step explanation: Start by saying the question out loud in a different format:

60% of what is $54?

We know that of means multiplication and is means equals. This helps us create the equation:

60% x what= $54

Then, we need to make 60% a number we can work with by changing it into a decimal: 0.6. We also need to make 'what' something easier to use as well, so we will use x in place of what:

0.6x=54

Then, get x by itself, which is also called isolating the variable. You do this by dividing by 0.6 on both sides, which is known as using inverse operations.

You should get x=90.

This means that $54 is 60% of $90 and $90 is Noah's goal.

A quadratic equation is x ax2+bx+c=0, which is a quadratic polynomial in a single variable. a 0. The Fundamental Theorem of Algebra ensures that it has at least one solution since this polynomial is of second order. Solutions may be simple or complicated. An equation that is quadratic is a quadratic equation. This indicates that it has at least one word that has to be squared.

systolic pressure for a person of age 45 years, just plug in y = 45:

systolic pressure is 127.54 mm Hg, plug in P = 127.54

P = 0.004y2 - 0.02y + 120

127.54 = 0.004y2 - 0.02y + 120

0 = 0.004y2 - 0.02y - 7.54

Use the quadratic formula to solve this. The quadratic formula (for ay2 + by + c = 0) is:

y = [-b ± √(b2 - 4ac)]/(2a)

In this case a = 0.004, b = - 0.02 and c = - 7.54 so:

[tex]y = [-b + \sqrt{(b2 - 4ac)]/(2a)}\\y = [-(-0.02) +\sqrt{((0.02)2 - 4(0.004)(-7.54))]/(2(0.004))}\\y = [0.02 + \sqrt{(0.0004 + 0.12064)]/0.008}\\y = [0.02 + \sqrt{0.12104]/0.008}\\y = [0.02+ 0.3479]/0.008\\ y = [0.02 + 0.3479]/0.008 or y = 0.3679/0.008 = 45.989\\ y = [0.02 - 0.3479]/0.008 or y = -0.3279/0.008 = -40.989\\[/tex]

1. y = -1.15x + 102.8 is the equation of the line of best fit.

2. Using the line of best fit's equation, the estimated price is: $62.55.

A mathematical statement that has a "equal to" symbol between two expressions with equal values is called an equation.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

We have LHS = RHS (left hand side = right hand side) in every mathematical equation.

To determine the value of an unknown variable that represents an unknown quantity, equations can be solved.

A statement is not an equation if it has no "equal to" sign.

According to our question-

1. Making use of the two points (20, 80) and (72, 20)

Slope (m) is equal to change in y/change in x, or (80 - 20)/(20 - 72) = 60/-52.

Slope is -1.15 meters.

Change y - b = m to m = -3 and (a, b) = (72, 20). (x - a)

y - 20 = -1.15(x - 72) (x - 72)

y - 20 = -1.15x + 82.8

y = -1.15x + 82.8 + 20

y = -1.15x + 102.8

The best line of fit is the equation y = -1.15x + 102.8.

2. To calculate the monthly heating expense, y, for a month with an average temperature of 35°F (x), enter x = 35 into the formula: y = -1.15x + 102.8.

y = -1.15(35) + 102.8

y = 62.55

Answer: X = 88, Y = 26, Z = 11.2

Step-by-step explanation:

First thing is use any linear pair equation that only has one variable.

1. 2x-30 + 34 = 180, Y = 88

Plug in the value of X to a two-variable equation to find the value of y.

2. 2y +88 + 40 = 180, Y = 26

Lastly repeat this step for finding the value of z.

3. 88 + 39 + 5z - 3 = 180, Z = 11.2

Answer: x = 88, y = 26, z = 26

Step-by-step explanation:

The shape shown in the picture is a heptagon.

Sum of interior angle = 900 degrees

Add all the interior angles

x+40+x+22+142+x+39+133+2x-30+114

=5x+460

5x+460=900

5x = 440

x = 88

2y is the exterior angle of x+40

to get 2y, you need to subtract x+40 from 180.

x = 88,

x+40 = 128

2y = 180-128 = 52

y = 26

5z-3 is the exterior angle of x+39

same thing for 5z-3

x = 88,

x+39 = 127

5z-3 = 127

5z = 130

z = 26

In mathematics, a revolution is a full rotation, or a full 360-degree turn. The item starts and ends in the same location during a 360-degree revolution.

The circumference of the wheel is equal to the length of a full revolution, or 2*pi*radius. The whole rotation of the wheel is 360 degrees.

The eight of the point is 6 feet, and the wheel's radius is 1 feet.

The point will be in its initial position, which is 6 feet high.

The height will thus be a = 6 + 0 = 6 ft.

The point will reach half the whole height of the wheel, or 2 feet, when the distance travelled is pi/2.

Height of b = 6 + 1 = 7 feet will result.

The point will be at the top of the wheel, which is 2 feet higher than the lower point of the wheel, when the distance travelled equals pi.

The height will thus be c = 6 + 2 = 8 ft.

The point will be half the whole height of the wheel, or 2 feet, when the distance travelled is 3 pi/2.

The height will thus be d = 6 + 1 = 7 ft.
