14. Explain why triangle ABC is similar to triangle ADE. (Hint: rays of light are parallel.)

Answer:

d

Step-by-step explanation:

the square root of 121 is 11

the square root of 64 is 8

soooo

(11x+8y)(11x-8y) makes the most sense

Answer:

D. (11x + 8y) (11x - 8y)

Step-by-step explanation:

Step 1: Rewrite 121x² - 64y² as (11x)² - (8y)²

Step 2: The difference of squares can be factored using the rule:

a² - b² = (a - b) (a + b)

(11x - 8y) (11x + 8y)

or

you can write it as

(11x + 8y) (11x - 8y)

Answer:

0.0000638

Step-by-step explanation:

all you need to do is move the decimal point over 5 times but this will only work if your multiply by 10 and that it has a negative exponent

The number 6.38×10⁻⁵ written in ordinary form is 1/638000.

In scientific notations numbers are written in the form of a base that is

0  ≤ b < 10 and multiplied by 10ⁿ where n represents integers.

We write large standard numbers in scientific form in a compact manner.

Given, A number in scientific form as 6.38×10⁻⁵.

Now, We know an exponent must be written as a positive value.

Therefore,

6.38×10⁻⁵.

= 1/ 6.38×10⁵.

Now, The ordinary form of the number is when we write without the exponent.

So,

1/ 6.38×10⁵ is,

= 1/638000.

For trade between countries of Brazil, Argentina, Ecuador, and Venezuela, the difference of the highest  and lowest balance of trade is $500,300,000.

Table is a way to represent the data of the two or more variable. To read the data from the table look for the value of one variable, and get the resultant value of other variable from the corresponding block.

Suppose that the countries of Brazil, Argentina, Ecuador, and Venezuela have interdependent economies.

The following table shows the imports and exports between each of these countries.

All prices given in millions of equivalent US dollars.

The trade of all the countries can be calculated as,

Brazil Argentina 4,691, Brazil Ecuador 4,791, Brazil Venezuela 1,526

[tex]B=4,691 +4,791 +1,526 =11008\rm millon[/tex]

Venezuela Brazil 4,535 Venezuela Argentina 1,577 Venezuela Ecuador 1,871

[tex]V=4,535 +1,577 +1,871=7983\rm million[/tex]

The highest trade is for Brazil and lowest is for Argentina. The difference between two is,

we need to remember :

tan(angle) = sin(angle) / cos(angle)

x>8 and x<2 are the two possible inequalities of |x - 5| > 3

a relationship between two expressions or values that are not equal to each other is called 'inequality.

Let x be the number

|x - 5| > 3

Now solve for x.

Suppose x - 5 is positive.  Then

x - 5 > 3

x > 8

Suppose x - 5 is negative.  Then |x - 5| = -(x - 5) = 5 - x

5-x>3

5-3>x

2>x

Step-by-step explanation:

the general equation for a line is usually

y = ax + b

a is the slope (the inclination) of the line indicating how flat or steep (and up or down) the line goes. it is the ratio of "y coordinate change / x coordinate change" when going from one point on the line to another.

and b is the y-intercept, the y value for x=0, the point, where the line intercepts the y-axis.

the origin is the point (0, 0).

that gives us the y-intercept (b) right away, as this is therefore clearly the point, where the line intercepts the y-axis. so, b = 0.

and going from (0, 0) to (-2, 10) we see

x changes by -2 (from 0 to -2).

y changes by +10 (from 0 to 10).

so, the slope is +10/-2 = -5.

and the line equation is

y = -5x

[tex]\huge \text{Hello there! :)}[/tex]

Answer:

[tex]y=-5x[/tex]

Step-by-step explanation:

Given that the equation of a line passes through the origin and the point (-2,10), we can get the equation of the line below.

The slope-intercept form of the equation of the line is given as;

[tex]y=mx+b[/tex]

where m = slope and y = intercept

The formula for the slope is given as

[tex]\frac{y^{2-yx^{1} } }{x^{2-x^{1} }}[/tex]

The given points are the origin are (0,0) and (-2, 10)

[tex]m=\frac{10~-~0}{-2~-0} =\frac{10}{-2} =-5[/tex]

Now use the point-slope formula to solve for the equation of the line.

[tex](y-y^{1})=m(x-x^{1})[/tex]

For this situation, we are given the slope of -5 and (-2,10)

[tex]y-10=-5(x-(-2))[/tex]

[tex]y-10=5x-10[/tex]

[tex]Y+5x=+10-10[/tex]

[tex]y+5x=0[/tex]

[tex]y=-5x[/tex]

Therefore, the Answer is [tex]y=-5x[/tex]
