Answers

Answer 1

The value of this expression if a = -7 and b = -3 is -352

Equation

Equation is an expression used to show the relationship between two or more numbers or variables.

Given that a = -7 and b = -3

Hence:

a³ - b²

Substituting the values of a and b:

= (-7)³ - (-3)²

= -343 - 9

Simplifying the equation:

= -352

a³ - b² = -352

The value of this expression if a = -7 and b = -3 is -352

The quadratic regression equation that fits these data is -1.107 X² +3.736 X +10.643 .

What is Quadratic Regression ?

A quadratic regression is the process of finding the equation of the parabola that best fits a set of data. As a result, we get an equation of the form:

y=ax2+bx+c where a≠0 .

The best way to find this equation manually is by using the least squares method.

That is, we need to find the values of a ,b,  and  c such that the squared vertical distance between each point (xi,yi) and the quadratic curve y=ax2+bx+c is minimal.

After solving we get the values of a , b, and c and thus we form the equation

-1.107 X² +3.736 X +10.643

What is the inverse of the function y = 2x + 3?

Answers

Answer:

y = x/2 - 3/2

Step-by-step explanation:

Answer:

y = x/2 - 3/2

Step-by-step explanation:

First, get x on its own:

Subtract 3 from each side

y - 3 = 2x

Divide through by 2

y/2 - 3/2 = x

or x = y/2 - 3/2

Now simply switch labels: x↔y

y = x/2 - 3/2

Find (f - g)(x).

Answers

Answer:

  (f -g)(x) = -3x^3 +x^2 +2x

Step-by-step explanation:

We assume the expression for g(x) has a typo, and the first term should be 3x^3.

(f -g)(x) = f(x) -g(x) = (3x^2 -2x -9) -(3x^3 +2x^2 -4x -9)

  = 3x^2 -2x -9 -3x^3 -2x^2 +4x +9

  = -3x^3 +(3 -2)x^2 +(-2+4)x +(-9+9)

(f -g)(x) = -3x^3 +x^2 +2x

Maggie bought c CDs for $12 each, b books for $7 each, and a purse costing $24.

a. Write an expression to show the total amount of money Maggie spent.

b. If Maggie bought 4 CDs and 3 books, how much money did she spend?

Answers

Step-by-step explanation:

Given that,

Maggie bought c CDs for $12 each, b books for $7 each, and a purse costing $24.

(a) Cost of c CDs = 12c

Cost of b books = 7b

Cost of p purse = 24p

Total amount = 12c+7b+24p

(b) Cost of 4 CDs = 12(4) = $48

Cost of 3 books = 7(3) = $21

Hence, this is the required solution.

h^2 = p^2 + b^2

90×90=p^2+50×50

90×90-50×50=p^2
