If x1 and x2 are the roots of the equation x^2 +5x-3=0, determine the value of x1^2 + x2^2. I know that I have to use vietas for
Arturiano [62]

Answer:

31

Step-by-step explanation:

Given

x² + 5x - 3 = 0

with a = 1, b = 5, c= - 3 , then

sum of roots x₁ + x₂ = - \frac{b}{a} = - \frac{5}{1} = - 5

product of roots = \frac{c}{a} = \frac{-3}{1} = - 3

Now

(x₁ + x₂)² = x₁² + 2x₁x₂ + x₂² , that is

(- 5)² = x₁² + 2(- 3) + x₂²

25 = x₁² - 6 + x₂² ( add 6 to both sides ), then

x₁² + x₂² = 31

For the graphed function f(x) = (4)x − 1 + 2, calculate the average rate of change from x = 1 to x = 2.
lorasvet [3.4K]

Average rate of the function: 3

Step-by-step explanation:

The function in this problem is

f(x)=4^{x-1}+2

The average rate of change of a function over an interval (x_1,x_2) is given by

r=\frac{f(x_2)-f(x_1)}{x_2-x_1}

where

f(x_1),f(x_2) are the values of the function calculated in x_1,x_2 respectively

For the function in this problem we have:

x_1=1, so

f(x_1)=f(1)=4^{1-1}+2=4^0+2=1+2=3

x_2=2, so

f(x_2)=f(2)=4^{2-1}+2=4^1+2=4+2=6

So, the average rate of change is

r=\frac{6-3}{2-1}=\frac{3}{1}=3

Simplify quantity 15 x squared minus 18 end quantity over 6. 15x + 3 x + 3 quantity 5 x squared minus 18 end quantity over 2 qua
Maru [420]

The expressions are:

  • (5x² - 6)/ 2
  • 5x² - 18/2
  • 5x² -6 /2
<h3 /><h3>What is expression?</h3>

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:

  • An absolute numerical number is referred to as a constant.
  • Variable: A symbol without a set value is referred to as a variable.
  • Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.
  • Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.

Given:

15 x squared minus 18 end quantity over 6.

= 15x² - 18 / 6

= 3(5x² - 6)/ 6

= (5x² - 6)/ 2

and, 5 x squared minus 18 end quantity over 2

= 5x² - 18/2

and, 5 x squared minus 6 end quantity over 2

= 5x² -6 /2
