Answer:

Step-by-step explanation:

cos²x = 1-sin²x = 1-(5/13)² = 144/169

cosx = √(144/169) = 12/13

tanx = sinx/cosx = (5/13)/(12/13) = (5/13)×(13/12) = 5/12

Question:

aivan3 [116]

Answer:

part A) The scale factor of the sides (small to large) is 1/2

part B) Te ratio of the areas (small to large) is 1/4

part C) see the explanation

Step-by-step explanation:

Part A) Determine the scale factor of the sides (small to large).

we know that

The dilation is a non rigid transformation that produce similar figures

If two figures are similar, then the ratio of its corresponding sides is proportional

Let

z ----> the scale factor

$\frac{CB}{C'B'}=\frac{CD}{C'D'}=\frac{BD}{B'D'}$

The scale factor is equal to

$z=\frac{CB}{C'B'}$

substitute

$z=\frac{4}{8}$

simplify

$z=\frac{1}{2}$

Part B) What is the ratio of the areas (small to large)?

Area of the small triangle

$A=\frac{1}{2}(2)(4)=4\ units^2$

Area of the large triangle

$A=\frac{1}{2}(4)(8)=16\ units^2$

ratio of the areas (small to large)

$ratio=\frac{4}{16}=\frac{1}{4}$

Part C) Write a generalization about the ratio of the sides and the ratio of the areas of similar figures

In similar figures the ratio of its corresponding sides is proportional and this ratio is called the scale factor

In similar figures the ratio of its areas is equal to the scale factor squared

How is volume measured? i need a formula using cubes or unit cubes. PLEASE HELP!

gulaghasi [49]

Answer:

The volume of solids is measured in cubic measurements.

Step-by-step explanation:

Examples:

Volume of a cube: V = a^3

Volume of a sphere: 4/3 x pi x r^3

Volume of a triangle: 1/2 x b x h x l

For instance, a sphere with the radius of 5 feet:

4/3 x pi x 5^3 = V

V = 523.6 cubic feet

Write a function g whose graph is a translation 2 units to the left of the graph of f (x) = |x| - 5

White raven [17]

A function is g(x) = |x+2| - 5 whose graph is a translation 2 units to the left of the graph of f (x) = |x| - 5.

<h3>What is a function?</h3>

A function is defined as the expression that set up the relationship between the dependent variable and independent variable. A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

The given function f(x) = |x| - 5 after transaltion of the graph by 2 units left will become g(x) = |x+2| - 5.

The graph of the function is attached with the answer below. In which both functions are graphed.

Therefore, afunction is g(x) = |x+2| - 5 whose graph is a translation 2 units to the left of the graph of f (x) = |x| - 5.
