An expression is defined as a set of numbers, variables, and mathematical operations. The value of the given expression when simplified is equal to 25/27. The correct option is B.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The given expression can be simplified as shown below,

(3²·3⁻⁵) / (5⁻²)

Using the rule of exponentials, x⁻ⁿ = 1/xⁿ,

= 3² · 3⁻⁵ · 5²

Using the rule of exponentials, mⁿ · mᵇ = m⁽ⁿ⁺ᵇ⁾,

= 3⁽²⁻⁵⁾ · 5²

= 3⁻³ · 5²

Using the rule of exponentials, x⁻ⁿ = 1/xⁿ,

= 5²/3³

= 25/27

Hence, the value of the given expression when simplified is equal to 25/27.

For the values k = 9 and k = -9 the roots of the quadratic equation

3x²+ 2kx + 27 = 0 real and equal.

What is quadratic equation?

Any equation in algebra that can be rearranged in standard form as: \(ax^2 + bx + c = 0\)   is known as a quadratic equation (from the Latin quadratus, "square").

where a ≠ 0 and a, b, and c are known numbers, x is an unknown value, and a. The equation is linear, not quadratic, if a = 0 and b ≠ 0. The coefficients of the equation, denoted by the numbers a, b, and c, are the quadratic coefficient, linear coefficient, and constant or free term, respectively.

The given equation is,

\(3x^2 + 2kx + 27 = 0\)

⇒  a = 3, b = 2k, c = 27

It is given that roots are real and equal.

Therefore,

\(b^2 - 4ac = 0\)

Plug the values of a, b, c in the above equation.

⇒

\((2k)^2 - 4(3)(27) = 0\\4k^2 - 324=0\\4k^2 = 324\\k^2 = 81\)

k = ±9

Hence, for the values k = 9 and k = -9 the roots of the quadratic equation  3x²+ 2kx + 27 = 0 real and equal.

Answer:

it is b y=7 done okays hope you like it

Answer:
B, y = 7.

Step-by-step explanation:
If 6y = 42, then all we have to do is divide both sides by 6.

Therefore,
y = 42/6
y = 7.

A is wrong since the slopes are clearly different, f(x) goes up by 3 every time while g(x) goes up by 1 every time.

B is also wrong since they are both going up, if they were opposites, one would be going up while the other went down.

C is also wrong since the y-intercepts are not the same, in f(x), the y-intercept is at (0,-4), and in g(x) the y-intercept is at (0,4).

In this design, there are two or more independent variables (IVs) that are manipulated by the researcher.

And one or more measured variables, also known as participant variables (PVs), that are measured but not manipulated.

Factorial designs are used to investigate the effects of multiple independent variables on a dependent variable.

The cost of rent from 8:00 AM to 2:00 PM is $21 and for 2:15 PM is $22.5

A unit rate means a rate for one of something.

Given is a graph showing the cost of renting snowshoes for corresponding hours,

From 8:00 AM to 2:00 PM = 6 hours

According to graph,

The rent for 6 hours is $21

In an hour, the rent is $6

So, for 15 minutes = $1.5

Therefore, 8:00 AM to 2:15 PM = 6 hours + 15 minutes

Cost = 21+1.5

Cost = $22.5

Hence, The cost of rent from 8:00 AM to 2:00 PM is $21 and for 2:15 PM is $22.5

Step-by-step explanation:

We can see that the statement is not always true for any vectors u and v in V3.

The statement is not always true.

The cross product of vectors u and v in V3 is a vector that is orthogonal to both u and v. That is,

u x v ⊥ u and u x v ⊥ v

However, this does not necessarily mean that (u x v) * u = 0 for all u and v in V3.

For example, let u = <1, 0, 0> and v = <0, 1, 0>. Then,

u x v = <0, 0, 1>

(u x v) * u = <0, 0, 1> * <1, 0, 0> = 0

So in this case, the statement is true. However, consider the vectors u = <1, 1, 0> and v = <0, 1, 1>. Then,

u x v = <1, -1, 1>

(u x v) * u = <1, -1, 1> * <1, 1, 0> = 0

So in this case, the statement is also true. However, if we take the vector u = <1, 0, 0> and v = <0, 0, 1>, then

u x v = <0, 1, 0>

(u x v) * u = <0, 1, 0> * <1, 0, 0> = 0

So in this case, the statement is true as well.

However, if we take the vector u = <1, 1, 1> and v = <0, 1, 0>, then

u x v = <1, 0, 1>

(u x v) * u = <1, 0, 1> * <1, 1, 1> = 2

So in this case, the statement is not true.

Therefore, we can see that the statement is not always true for any vectors u and v in V3.

Thus answer is ∥u(x)∥ = 2√(65)/5 and ∥v(x)∥ = √(7/2).

To verify if two functions u(x) and v(x) are orthogonal on the interval [−1,1], we need to check if their inner product over that interval is zero. The inner product of two functions u(x) and v(x) is given by:

⟨u,v⟩ = ∫[−1,1] u(x)v(x) dx

Let's calculate the inner product and check if it equals zero:

∫[−1,1] u(x)v(x) dx = ∫[−1,1] (x^3 - x) (3x^2 + 1) dx

Expanding and integrating:

∫[−1,1] (3x^5 + x^3 - 3x^3 - x) dx = ∫[−1,1] (3x^5 - 2x^3 - x) dx = 0

Since the inner product is zero, we can conclude that the functions u(x) and v(x) are orthogonal on the interval [−1,1].

Next, let's calculate the norms of u(x) and v(x):

∥u(x)∥ = √(∫[−1,1] (x^3 - x)^2 dx) = √(52/5) = √(260/25) = 2√(13/5) = 2√(65)/5

∥v(x)∥ = √(∫[−1,1] (3x^2 + 1)^2 dx) = √(7/2)

Therefore, ∥u(x)∥ = 2√(65)/5 and ∥v(x)∥ = √(7/2).

A function is a relation between sets where for each input, there is exactly one output.

A mathematical phrase, rule, or law establishes the link between an independent variable and a dependent variable (the dependent variable). Functions can be found everywhere in mathematics, and they are essential for building physical connections in the sciences.

The German mathematician Peter Dirichlet initially offered the contemporary definition of function in 1837: A variable y is said to be a function of the independent variable x if there is a relationship between them such that whenever a numerical value is assigned to x, there is a rule that determines a specific value of y.

If the line has a positive slope, it means that the amount is increasing, and if it has a negative slope, it means that the amount is decreasing.

Based on the given information, the function models the amount of money a new business has made over x months. Therefore, we can assume that the function is a linear function, and its graph is a straight line.

Given that negative values represent debt, we can assume that the slope of the line is positive over the interval where the function takes positive values. Therefore, the interval over which the amount is increasing is from zero to infinity, which means that the business is making money and not in debt.

It's essential to note that if the function has a negative slope over any interval, then the amount is decreasing, and the business is losing money. However, we cannot determine this information from the given function's information.

If you make annual payments of $1400 for 8 years at a 6% interest rate compounded annually, the total amount accumulated over the 8-year period would be approximately $12,350.

To explain further, when you make annual payments of $1400 for 8 years, you are essentially depositing $1400 into an account each year. The interest rate of 6% compounded annually means that the interest is added to the account balance once a year.

To calculate the total amount accumulated, you can use the formula for the future value of an ordinary annuity:

FV = P * ((1 + r)^n - 1) / r

where FV is the future value, P is the payment amount, r is the interest rate per compounding period (in this case, 6% or 0.06), and n is the number of compounding periods (in this case, 8 years).

Plugging in the values, we have:

FV = $1400 * ((1 + 0.06)^8 - 1) / 0.06

≈ $12,350

Therefore, the total amount accumulated over the 8-year period would be approximately $12,350.

The index number indicates that the value in period 7 has increased by about 119.83% compared to the value in period 1.

Based on the information provided, we will calculate the simple index number for period 7 (i7) using the given values for y1 and y7.

The simple index number formula is:

i7 = (y7 / y1) × 100

Where y1 represents the value in period 1 (116) and y7 represents the value in period 7 (255).

Plugging in these values, we get: i7 = (255 / 116) × 100 i7 ≈ 219.83

Thus, the simple index number for period 7 (i7) is approximately 219.83.

This index number is a measure that compares the value of y7 to the value of y1, with y1 being the base period.

In this case, the index number indicates that the value in period 7 has increased by about 119.83% compared to the value in period 1.
