The term "length" is used to describe an object's size or the separation between two points. Lindsey must buy 4 feet of the board for the ramp itself.

The term "length" refers to the measurement or size of something from end to end. In other terms, it is the greater of the upper two or third dimension of a geometric shape or object.

Distance exists estimated in length. The length contain the dimension of distance in the International System of Quantities. The majority of measurement systems select a base unit for length from which all other units exists derived. The meter serves as the foundational unit of length in the International System of Units.

A rectangle, for instance, has length and width as its dimensions.

1/x = 15°

x = 1/sin 15°

simplifying the above equation, we get

x = 3.9ft

x ≈ 4 ft

Therefore, the value of x ≈ 4 ft.

Using trigonometric functions, the value of 2 cos x is equals to √3.

One of the six mathematical functions used to express the side ratios of right triangles, the trigonometric function includes the sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). The graphic shows these six trigonometric functions in respect to a right triangle.

Cos (π/6) = √3/2

So. f(x) = 2 cos x

⇒ f(x) = 2 cos(π/6)

⇒ f(x) = 2 × √3/2

f(x) = √3

The initial amount and rate of change given a table for a linear function are $332 and $22.5, respectively

The table of linear function represents the given parameter

On the table, we have the following points

(x, y) = (6, 467) and (10, 647)

The rate of change is calculated as

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

So, we have

Rate = (647 - 467)/(10 - 2)

Evaluate

Rate = 22.5

This means that the rate of change is $22.5

The initial amount is calculated as

y = m(x - x1) + y1

Where

m = 22.5

So, we have

y = 22.5(x - x1) + y1

Using one of the points, we have

y = 22.5(x - 6) + 467

Set x = 0

So, we have

y = 22.5(0 - 6) + 467

Evaluate

y = 332

Hence, the initial amount and rate of change given a table for a linear function are $332 and $22.5, respectively

The inequality which can be used to determine the number of gigabytes is 58 + 3x < 70 and the solution is  x < 4

The given parameters are

Flat cost = $58

Rate = $3 per gigabyte

Budget = Under $70

The equation is represented as:

Total cost = Flat cost + Rate * Number of gigabyte

So, we have

y = 58 + 3x

The budget is under 70

So, we have

58 + 3x < 70

Subtract 58 from both sides

So, we have

3x < 12

Divide both sides by 3

So, we have

x < 4

Hence. the inequality which can be used to determine the number of gigabytes is 58 + 3x < 70 and the solution is  x < 4

The wavelength of the waves on a string that is vibrating at 220 MHz is 2.20 m. These waves move at a 4840 rpm rate as they move up and down the string.

A waveform signal that is carried in space or down a wire has a wavelength, which is the separation between two identical places (adjacent crests) in the consecutive cycles. This length is typically defined in wireless systems in meters (m), centimeters (cm), or millimeters (mm) (mm). According to the available data, the wavelength is more frequently expressed in nanometers (nm), which are units of 10-9 m, or angstroms (), which are units of 10-10 m, for infrared (IR), visible light (VL), ultraviolet (UV), and gamma radiation ().

The eighth term of the given geometric sequence is: 0.00183.

A geometric progression, sometimes referred to as a geometric sequence in mathematics, is a series of non-zero numbers where each term following the first is obtained by multiplying the preceding one by a constant, non-zero value known as the common ratio.

Given: -30, 7.5, -1.875, ....

Here, [tex]\frac{7.5}{-30}=\frac{-1.875}{7.5}=-0.25[/tex]

That is, the given geometric sequence has a₁ = -30 and r = -0.25

The nth term of a geometric sequence is given by: [tex]a_n=a_1(r^{n-1})[/tex]

The value of the factorial expression is 99/10

The expression is given as

98!/100! x 10

The above expression implies that we multiply 10 by the quotient of 98! and 100!

This can be done directly using a calculator, and it can be solved step by step

The step by step procedure is as follows

Expand the denominator

98!/100! x 10 = 98!/100 * 99 * 98! x 10

Evaluate the quotient

98!/100! x 10 = 1/100 * 99 x 10

This gives

98!/100! x 10 = 1/10 * 99

Evaluate the product

98!/100! x 10 = 99/10

The other root of the given quadratic equation is a = ± 3/√2.

Given that, x=2 and x²+ax+12=0.

The roots of a quadratic equation are the values of the variable that satisfy the equation. They are also known as the "solutions" or "zeros" of the quadratic equation.

Now, put x=2 in x²+ax+12=0 and find the value of a.

That is, 2²+2a+12=0

⇒4+12+2a=0

⇒16+2a=0

⇒2a=-16

⇒a=-8

So, the value of a is -8.

Put (0, 6) and (4, 6) in the function y=2x²+bx+c and find the value of b and c.

That is, 6=2(0)²+b(0)+c

⇒ c=6

6=2(4)²+b(4)+c

⇒ 6 = 32+4b+c

⇒ -26 = 4b + 6

⇒ 4b = -32

⇒ b = -8

So, the value of b is -8 and the value of c is 6.

Put x=a (root) in the equation 2x + x/a -9 = 0 and find the other root.

That is, 2a²+a/a -9 = 0

⇒ 2a² - 9 = 0

⇒ a²=9/2

⇒ a = ± 3/√2

Therefore, the other root of the given quadratic equation is a = ± 3/√2.
