The given function is of quadratic type. Therefore, the correct option is option C among all the given options.

A mathematical phrase, rule, or law that establishes the link between an independent variable and a predictor variables (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

Expressions of well-known functions can be found in many frequently used mathematical formulas. As an illustration, the formula A = r2 for both the area of either a circle plots the predictor variables A (this same area) as little more than a consequence of the regression coefficient r. (the radius).

Mathematical functions with more than two variables, often known as multivariable or multivariate functions, are frequently used; this is seen by the triangle's area formula. The given function is of quadratic type.

Therefore, the correct option is option C.

Answer:

x=8 , x=-1

Step-by-step explanation:

let the number is x

According to the condition

[tex] {x}^{2} - 8 = 7x \\ {x}^{2} - 7x - 8 = 0 \\ {x}^{2} - 8x + x - 8 = 0 \\ x(x - 8) + 1(x - 8) = 0 \\ (x - 8)(x + 1) = 0 \\ x - 8 = 0 \: or \: x + 1 = 0 \\ x = 8 \: or x = - 1[/tex]

Answer:

[tex]\displaystyle \begin{aligned} \displaystyle (n+1)^2 - n^2 &= 2n +1 \\ &= n (n+1)\end{aligned}[/tex]

Where ? = 2.

Step-by-step explanation:

We want to prove that the difference of the squares of two successive integers is equal to the sum of the integers.

In other words, we want to show that for any given integer n:

[tex]\displaystyle (n+1)^2 - n^2 = n + (n+1)[/tex]

From the original equation, expand:

[tex]\displaystyle = (n^2 + 2n + 1) - n^2[/tex]

Combine like terms:

[tex]= 2n +1[/tex]

And rewrite. Hence:

[tex]\displaystyle = n + (n + 1)[/tex]

Therefore:

[tex]\displaystyle \begin{aligned} \displaystyle (n+1)^2 - n^2 &= 2n +1 \\ &= n (n+1)\end{aligned}[/tex]

In conclusion, ? = 2.

Answer:

To find cosθ, use the formula for the area of a triangle i.e. AREA=1/2 x a x b x sinC.=> For this case: 15= 1/2 x 10 x 5 x sinC to find sinC.=> SinC = 3/5 thus, Arcsin(3/5)=+- 4/5 or +-0.8

To find the exact length of BC, use the cosine rule.=> c(sq)=a(sq)+b(sq)-2abCosC=> c(sq)=10(sq)+5(sq)-2(10)(5)(+-4/5)=> c(sq)= Square root of 205

Step-by-step explanation:

a=31

b=27

A = 46 degree

now, Area of ️ABC =ab siny÷2

=31×27 sin46÷2

The profitability of the restaurant is when the function gives a value greater than 0. The franchise does not make a profit after 5, 3, 2 or 1 month of opening.

Given that:

[tex]P(t) = t^4 - 9t^3 + 24t^2 - 20t[/tex]

To calculate the profit, we simply substitute the values of t in the above equation.

(a) 5 months

This means [tex]t =5[/tex]

So, we have:

[tex]P(5) = 5^4 - 9\times 5^3 + 24 \times 5^2 - 20 \times 5[/tex]

[tex]P(5) = 0[/tex]

(b) 3 months

This means that [tex]t=3[/tex]

So, we have:

[tex]P(3) = 3^4 - 9 \times 3^3 + 24 \times 3^2 - 20 \times 3[/tex]

[tex]P(3) = -6[/tex]

(c) 2 months

This means that [tex]t = 2[/tex]

So, we have:

[tex]P(2) = 2^4 - 9 \times 2^3 + 24 \times 2^2 - 20 \times 2[/tex]

[tex]P(2) = 0[/tex]

(d) 1 month

This means that [tex]t = 1[/tex]

So, we have:

[tex]P(1) = 1^4 - 9 \times 1^3 + 24 \times 1^2 - 20 \times 1[/tex]

[tex]P(1) = -4[/tex]

For the restaurant to make a profit, the equation has to give a positive value. Since none of the values of t gives a positive value for P(t).

Then, we can say the franchise does not make a profit after 5, 3, 2 or 1 month of opening.

  (c)  symmetric property

Step-by-step explanation:

The symmetric property of equality lets you swap sides of the equal sign.

__

Reflexive: A = A

Substitution: if A=B and A=C, then C=B

Symmetric: A = B  ⇔  B = A

Transitive: if A = B and B = C, then A = C.

  note that the substitution and transitive properties are almost indistinguishable.

The properties that justify each line is:

The expressions are given as:

[tex]c(bd)[/tex]

[tex](cb)d[/tex]

Notice that only the positioning of the variables are changed, the operator within the variables remain the same (i.e. the multiplication)

Hence, the properties that justify the three lines is the associative property of multiplication
