Jennifer walks 9 blocks south and 5 blocks west. Approximately how many blocks is she from home if she were to take a direct pat
rodikova [14]

9514 1404 393

Answer:

  10.3

Step-by-step explanation:

Assuming the blocks are square, we can use the Pythagorean theorem to find the diagonal distance.

 d² = 9² +5² = 81 +25 = 106

 d = √106 ≈ 10.3

Jennifer is about 10.3 blocks from home.

1. Using the graph of the function f(x) shown below, answer the following questions.
Sphinxa [80]

Graphs can be used to represent functions, and vice verse

  • The values of f(-7), f(0), f(4) and f(9) are -6, 3, 1 and -4, respectively.
  • f(x) = 5 illustrate three values of x
  • The y-intercept is 3
  • The maximum and the minimum values of the graph are 5.5 and 6
  • The graph passes the vertical line test.

<u>(a) The values of f(-7), f(0), f(4) and f(9)</u>

  • At x = -7, the corresponding value of the function is -6.
  • At x = 0, the corresponding value of the function is 3.
  • At x = 4, the corresponding value of the function is 1
  • At x = 9, the corresponding value of the function is -4

Hence, the values of f(-7), f(0), f(4) and f(9) are -6, 3, 1 and -4, respectively.

<u>(b) The number of values of the x at f(x) = 5</u>

At f(x) =5, the values of x are -10, 1 and 3.

Hence, f(x) = 5 illustrate three values of x

<u>(c) The y-intercept</u>

This is the point where the graph crosses the y-axis, i.e. when x = 0.

Hence, the y-intercept is 3

<u>(d) The maximum and the minimum values of the graph</u>

The highest point on the graph is (2.5,5.5), while the least point is (-7,-6)

Hence, the maximum and the minimum values of the graph are 5.5 and 6, respectively.

<u>(e) Why the graph represents a function</u>

It represents a function because it passes the vertical line test.

This in other words means that, each x value has exactly one y value

4x^2-2x-4=0 solve using quadratic formula
MArishka [77]

Answer:

Step-by-step explanation:

Although you can start with 4x^2-2x-4=0, it's just slightly easier to reduce the coefficients.  4x^2-2x-4=0 becomes 2x^2 - x - 2 = 0.

The discriminant (part of the quadratic formula) is b^2 - 4ac.  Using b = -1. a = 1 and c = -2, we get (-1)^2 - 4(2)(-2), or 17.

                                                       -b ± √(b^2 - 4ac)

Then the quadratic formula   x = ---------------------------

                                                                 2a

                                         -(-1) ± √17           1 ± √17

takes on the values  x = -----------------  =  ---------------

                                                  4                      4
