Find the measure of x

For the given expression, the correct answer is C, 7x².√2x⁴.6√2x¹² = 84x¹⁰.

Finding the value of an algebraic expression when a specified integer is used to replace a variable is known as evaluating the expression. We use the given number to replace the expression's variable before applying the order of operations to simplify the expression.

A variable is a letter, like x, y, or z, that stands in for an arbitrary number. You must substitute a number for each variable and carry out the arithmetic operations in order to evaluate an algebraic expression. Since 6 + 6 equals 12, the variable x in the example above is equal to 6.

Given,

the expression is 7x².√2x⁴.6√2x¹²,

Solving the under root,

⇒ 7x².√2x².6√2x⁶

⇒ 7x² . √2 x². 6. √2 . x⁶     [√2 × √2 = 2]

⇒ 7 × 6 × 2 × x¹⁰ = 84 x¹⁰

The equation of this parallel line using point slope is  y = 4x - 31.

The equation of a straight line that passes through a particular point and is inclined at a specific angle to the x-axis may be found using the point slope form. Every point on a line must satisfy the equation for the line in order for it to exist. This implies that a line is represented by a linear equation in two variables.

Given that the equation of a line is y = 4x - 2.

Here, we observe that the slope m = 4

Parallel lines have the same slope. So, the slope of the new line is:

m = 4

Given that points (x1, y1) = (5, -11) are also in the new parallel line.

Using the Point-Slope form we can write:

y - y1 = m (x - x1)

Substitute the value of x and y coordinates in the above equation:

y - (-11) = 4 (x - 5)

y + 11 = 4x - 20

y = 4x - 20 -11

y = 4x - 31

Hence, the equation of this parallel line using point slope is  y = 4x - 31.

The position of the sprinter is equal to the value of definite integral of the given velocity function v(t). The position at t = 4, 7, and 9 is 8, 8, 0.

The velocity is the first derivative of the position function. The position function is given in the attached picture.

s'(t) = v(t)

The position at time t is therefore equal to the definite integral from t = 0 to time t.

Since the graph is linear, the evaluation of each definite integral is equal to the area of triangles underneath the lines.

∫₀⁴ v(t) dt = (1/2) x 2 x 6 = 6

∫₄⁷  v(t) dt = (1/2) x 1 x 8 - (1/2) x 2 x 4  = 0.

∫₇⁹  v(t) dt = 2 x (-4) = -8

The position at t = 0 is s(0) = 2

Hence,

s(4) = s(0) + ∫₀⁴ v(t) dt  = 2 + 6 = 8

s(7) = s(0) +  ∫₀⁴ v(t) dt + ∫₄⁷  v(t) dt = 2 + 6 + 0 = 8

s(9) = s(0) +  ∫₀⁴ v(t) dt + ∫₄⁷  v(t) dt  + ∫₇⁹  v(t) dt = 2 + 6 + 0 - 8 = 0

Algebra is a branch of mathematics that deals with mathematical symbols and the rules for manipulating these symbols. Algebra is used to solve problems and to describe patterns and relationships between variables. It is a powerful tool for modeling and understanding many types of real-world situations.

In algebra, letters or other symbols are used to represent numbers or quantities that are not known. These symbols can be manipulated using mathematical operations, such as addition, subtraction, multiplication, and division. Equations and inequalities involving these symbols can be solved to find the values of the unknowns. Algebraic equations can also be graphed to visualize the relationship between the variables.

To find the total number of vegetable seeds Frank is going to plant, we can add the number of seeds he is planting in each garden:

d + (3d + 6) = d + 3d + 6 = 4d + 6

A: The differential equation can be expressed in the form f(x ,y) = g(x)h(y) = 0, indicating that it is homogeneous. Divide both sides of the equation by y to observe this, which results in  dy/dx + sin^2(x) = cos^2(x)

B: Since there is just one function y and its derivative dy/dx involved in the equation, it is an ODE.

D: Because there is only one function y and its derivative  dy/dx involved in the equation, first-order differential equations are what it is.

G: The formula for the equation is a(x)y' + b(x)y = c(x), where a(x)=1, b(x) = sin^2(x), c(x) = cos^2(x) . Given that x and the coefficients of y and dy/dx are constants, the equation is linear.

H: The equation may be written as dy / y =  (cos^2(x))dx/(1+sin^2(x)),and it is a candidate for integrating factors because we can multiply both sides by (1+sin^2(x))dx .

I: The variables x and y can be separated by integrating both sides of the equation, which can be represented as  (dy/y) = (cos^2(x))dx/(1+sin^2(x)) + (sin^2(x))dx .

J: The equation is self-sufficient; it is not dependent on any explicit function of t.

A linear function consists of functions where the variables has exponents of 1. the relationship is expressed in the slope intercept form as below.

y = mx + c

definition of variable to suit the problem

y = output variable

m = slope

x = input variable

c = y intercept

The given equation is rewritten in slope intercept form as follows

8x + 13y = 26

y = 2 - 8/13 x

the slope is 8/13

For a perpendicular line the slope = -1/m

= -1/(8/13)

For a line to have a slope of -13/8, the points will be

-13/8 = (1 - 3) / (-4 - k)

The resulting quadratic equation is x^2 - x - 7 = 0.

The x-values for which f(x) < 1 can be determined by solving the inequality f(x) < 1.

Since f(x) is not given in the question, we must first define it. Let's assume f(x) = x^2 - 2x + 1.

The resulting equation is (x - 1)^2 < 0.

The function f(x) is defined as f(x) = x^2 - x - 6.

From here, the equation can be solved for x using the quadratic formula, which gives us x = [7 + sqrt(73)]/2 and x = [7 - sqrt(73)]/2.
