The pattern in that you add 3 each time. 2+3=5, 5+3=8, 8+3=11
Figure 4 would be 11

Three functions are given below: f(x), g(x), and h(x). Explain how to find the axis of symmetry for each function, and rank the
vredina [299]

9514 1404 393

Answer:

  f, h, g

Step-by-step explanation:

The axis of symmetry for a vertically-opening parabola is the line ...

  x = constant

where the constant is the x-coordinate of the vertex.

__

<u>h(x)</u>

The equation of f(x) is given in vertex form ...

  f(x) = a(x -h)² +k . . . . . vertex: (h, k)

where (h, k) = (-4, 1).

The axis of symmetry of f(x) is x = -4.

__

<u>g(x)</u>

The equation of g(x) is given in standard form ...

  g(x) = ax² +bx +c

The line of symmetry for this parabola is ...

  x = -b/(2a) = -(-16)/(2(2)) = 16/4 = 4

The axis of symmetry of g(x) is x = 4.

__

<u>h(x)</u>

The x-coordinate of the vertex can be read from the graph:

  x = 1

The axis of symmetry of h(x) is x = 1.

__

From smallest to largest, the rank is f(x), h(x), g(x).

A loan of £1000 has a compound interest rate of 2.7% charged monthly. Express the original loan as a percentage of the total amo
const2013 [10]

Answer:

£1054.729

Step-by-step explanation:

To find compound interest you need to use the equation 1000(1.027)^x.

To find the interest rate (1.027):

100 + 2.7 = 102.7

102.7 / 100 = 1.027

The value of x is the amount of months if no payment is made in this situation, so 2 would be the x value for this problem.

Hope this helps!

Skew lines a and b represent Donna's and Charlie's paths as they simultaneously walk on the first and second level of a shopping
vlabodo [156]

Answer: They cannot meet because two skew lines do not intersect each other.


Explanation:


Skew lines is a concept used in geometry to define lines that do not intersect each other but are not parallel.


In this case, the lines are not parallel because they lie in different planes, which in turn, do not intersect each other.


Therefore, runing the lnes in different planes and in different directions, they cannot not, in spite of not being parallel, intersect each other, which is called that the lines are skewed.


Donna's and Charlie's paths are an exelent illustration of what skew lines are: since Donna's and Charlie are in different levels, as long as each remains in parallel levels, their paths wiil not meet each other.
