Area of a parallelogram = b × h
Let the heights of first and second parallelogram be h and h' respectively.
Given that,
h = ½h'
Area of first parallelogram= bh ...(i)
Area of second parallelogram = bh'
but, h = ½h'
Replacing h by ½h' in equation (i)

Therefore, area of first parallelogram = ½bh'

Ratio - ½bh' : bh'
= 1:2

How do I find out what f(x) is if the graph defines h(x)
const2013 [10]

Answer:

f(x) = \frac{-h(x) + 7}{4}

Step-by-step explanation:

h(x) is defined by the formula,

h(x) = -4f(x) + 7

If the graph attached is of the function 'h' and we have to find the function 'f',

h(x) - 7 = -4f(x)

4.f(x) = -h(x) + 7

f(x) = \frac{-h(x) + 7}{4}

Therefore, function 'f' will be defined by,

f(x) = \frac{-h(x) + 7}{4}

Joan and her brother Justin left a hotel at the same time, driving in opposite directions at constant rates. After traveling for
inessss [21]

Answer:

Joan drive with a speed of 55 miles per hour.

Step-by-step explanation:

Given:- Travelling time (t) = 4 hours.

Travelled distance (d) = 480 miles.

Speed of Justin is 10 miles per hour faster than Joan.

To find:- Speed of Joan = ?

Solution:-

Let speed of Joan be x,

therefore speed of Justin = x+10          ---------------(from given)

Now, Total speed of Joan and Justin = x+x+10

Total speed of Joan and Justin = 2x+10 ------------(1)

Now formula for speed is,

Speed = \frac{distance}{time}

2x+10=\frac{480}{4}                        -------------(from 1 and given)

2x+10=120

2x=120-10

2x=110

\therefore x=\frac{110}{2}

\therefore x= 55

as x is the speed of Joan,

Therefore Joan drive with a speed of 55 miles per hour.
