Helena wrote the equation using point-slope form for the line that passes through the points (5, 1) and (3, 5). Analyze the step

viva [34]

Answer:

In step 2, she didn’t use an x and y from the same coordinate pair

Step-by-step explanation:

see the attached figure to better understand the problem

we have the points (5, 1) and (3, 5)

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute

$m=\frac{5-1}{3-5}$

$m=\frac{4}{-2}$

$m=-2$

step 2

The equation of the line in point slope form is

$y-y1=m(x-x1)$

take the point (3,5)

$m=-2$

substitute

$y-5=-2(x-3)$

$y-5=-2x+6$

$y=-2x+6+5$

step 3

$y=-2x+11$

therefore

In step 2, she didn’t use an x and y from the same coordinate pair

The length of the chord CE is 24.46 in

To find the length of the chord CE, we solve the question using pythagoras' theorem

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

A chord is a line segment touching two points in a circle.

<h3>What is pythagoras' theorem?</h3>

Pythagoras' theorem states that in any right angled triangle with sides a, b and c where c is the hypotenuse side, we have that

c² = a² + b²

<h3>The required triangle</h3>

Now form the diagram the radius of the circle BE forms a right angled triangle with the perpendicular to the chord, BO and the midway between the chord, OE.

BO = BD - OD

= 20 in - 5 in

= 15 in

From pythagoras,

BE² = DE² + BO²

making DE subject of the formula, we have

DE = √(BE² - BO²)

DE = √((20 in)² - (15 in)²)

DE = √(400 in² - 225 in²)

DE = √(175 in²)

DE = 13.23 cm

<h3>The length of the chord</h3>

Since the chord CE = 2DE,

So, CE = 2 × 13.23 in

= 26.46 in

So, the length of the chord CE is 24.46 in

A sports agent made one million dollars by charging a 12.5% commission to negotiate a long-term contract for a professional athl

Hatshy [7]

$1,000,000 = 12.5% of the contract

"12.5%" means 0.125

"of" means "times"

1,000,000 = 0.125 C

Divide each side by 0.125 :

C = 1,000,000 / 0.125 = <em>$8 million</em>
