A figure has vertices at the points (6,5), (6,-4), (-4,-4) and (-4,5). What is the area of the figure

Oxana [17]

Answer:

90 units²

Step-by-step explanation:

The rectangular figure is 10 units wide (from -4 to +6) and 9 units high (from -4 to +5), so its area is 10·9 = 90 square units.

What is 4/7 divided by 2/7

Nina [5.8K]

To divide one fraction by another, invert (turn upside-down) the second fraction, then multiply.
Divide: 4(/7) / 2 = 4/7 · 1/2 = 4*1/ 7*2 = 4/14 = 2/7

Nathaniel measured the height of one shelf on his bookcase. He wants to know which books will fit on the shelf. The shelf is 22.

UkoKoshka [18]

PART A - So the ruler is 22.86 centimeters tall, and after measuring with an inch ruler, is also 9 inches tall.
ruler = 22.86cm
ruler = 9 in
You can equate 22.86cm and 9in because they both equal the length of the ruler (transitive property).
22.86cm = 9in
Then you can write a proportionality equation.
$\frac{22.86cm}{9in} = \frac{x}{1in} \\$

Part B -
Cross multiplying,
$(9in)x = (22.86cm)1 \\ 
x = \frac{22.86cm}{9in}= 2.54cm/in$

Part C - We can use something called dimensional analysis - multiplying 12 cm by (1in/2.54cm) - in order to change the units from inches to cm. This is possible because 1in = 2.54cm, the fraction 1in/2.54cm = 1. And also the units cm will cancel out.
$\frac{12cm}{1} * \frac{1in}{2.54cm} = 4.72in$

Use the drop-down menus to complete the statements. in order for f–1(x) to be a function, the domain of f(x) can be restricted t

zmey [24]

Using concepts of the inverse function, it is found that:

The domain of f(x) has to be restricted to x >= 1. Under this restriction, the domain of f-1(x), would be (2,∞), having the same minimum value as the original function f(x).

<h3>How to find the inverse of an equation or a function?</h3>

To find the inverse, we have to exchange x and y and then isolate y. This can only happen if the function f(x) is injective, that is, each value of the output is related to only one value of the input. Then:

The domain of f(x) is the range of the inverse function f-1(x).

The range of f(x) is the domain of the inverse function f-1(x).

Researching this problem on the internet, we are given an absolute value function with vertex at x = 1, meaning that for the inverse, the domain of f(x) has to be restricted to x >= 1. The domain of the inverse would be the range of f(x), which is (2,∞).

Then:

The domain of f(x) has to be restricted to x >= 1. Under this restriction, the domain of f-1(x), would be (2,∞), having the same minimum value as the original function f(x).
