Answer:

3

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

here [ a, b ] = [ 1, 3 ]

f(b) = f(3) = 3² - 3 - 3 = 9 - 3 - 3 = 3

f(a) = f(1) = 1² - 1 - 3 = 1 - 1 - 3 = - 3

average rate of change = \frac{3+3}{3-1} = \frac{6}{2} = 3

Answer: \\ f(1) =  - 3 \\ f(3) = 3 \\ Average \:  rate \:  of \:  change: \\  \frac{f(3) - f(1)}{3 - 1}  =  \frac{6}{2}  = 3

Find the distance between the two points rounding to the nearest tenth (if necessary).
QveST [7]

The distance between two points having coordinates (4, -4) and (9, -2) plotted on the cartesian plane, and rounded to the nearest tenth, will be 5.40 units.

As per the question statement, two points having coordinates (4, -4) and

(9, -2) plotted on the cartesian plane.

We are required to calculate the distance between the above mentioned two points, rounded to the nearest tenth.

To solve this question,  we need to know the Distance-formula which goes as,

"The distance between any two points (x₁, y₁) and (x₂, y₂) can be given by √[(x₂ - x₁)² + (y₂ - y₁)²]"

Assuming that [(x₁, y₁) = (4, -4)] and [(x₂, y₂) = (9, -2)], and substituting these values in the above-mentioned distance formula, we get,

√[(9 - 4)² + {(-2) - (-4)}²]

= √[(9 - 4)² + {(-2) + 4}²]

= √[(9 - 4)² + (4 - 2)²]

=√[(5)² + (2)²]

=√(25 + 4)

=√29

= 5.38 units.

Therefore, rounding (5.38) to the nearest tenth, we get, 5.40.

That is, the distance between two points having coordinates (4, -4) and (9, -2) plotted on the cartesian plane, and rounded to the nearest tenth, will be 5.40 units.

  • Distance: In Mathematics, physics or daily life, distance is a numerical or occasionally qualitative measurement of how far objects or points are from each other.
  • Coordinates: In geometry, coordinates are a pair of numbers that can uniquely determine the position of points or other geometric elements on a Euclidean or Cartesian Plane.

Please help me with acellus
Bezzdna [24]

Answer:

66

Step-by-step explanation:

angle 1 and 4 are supplementary so the 2 added together equal 180. 180-124=56.

The sum of the triangles angles equal 180

180-56-58=66 which is the value of angle 2

What is a polynomial function in standard form with zeroes 1, 2, -2. and -3
Juli2301 [7.4K]
<span>A polynomial with the given zeros can be represented as
   f(x) = (x-1)(x-2)(x+2)(x+3).
   Note that if you set f(x) = 0, then 1,2,-2, and -3 certainly are the solutions. From here, we simply multiply/expand out the polynomial. We can do this in a variety of ways, one of which is taking the left two and right two products separately. We have
   (x-1)(x-2) = x^2 - 3x + 2
   and
   (x+2)(x+3) = x^2 + 5x + 6.
   This gives that
   f(x) = (x^2 - 3x + 2) (x^2 + 5x + 6).
   Expanding this expression out then gives us our answer as
    f(x) = x^4 + 2x^3 - 7x^2 - 8x + 12
   or answer choice B.</span>
