Answer:

Raul's claims are not correct

The equation of the graph is $y=\frac{10}{15}x$

Step-by-step explanation:

Part a)

we know that

The fact that the data form a straight line does not imply that it is a proportional relationship. In order for it to be a proportional relationship, in addition to the fact that a straight line must be formed, it must pass through the origin.

In this problem the graph shows a proportional relationship because the data forms a straight line and passes through the origin (0,0)

therefore

The claim that the graph shows a proportional relationship because the data forms a straight line is not correct

Part B)

<u>Find the slope of the straight line</u>

Let

$A(0,0),B(15,10)$

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

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

substitute the values

$m=\frac{10-0}{15-0}$

$m=\frac{10}{15}=0.67\frac{pages}{minute}$

therefore

The claim that he reads 1.5 pages per minute is not correct

Part C)

The equation of the graph is equal to

$y=\frac{10}{15}x$

Se implicit differentiation to find an equation of the tangent line to the curve at the given point.7x2 + xy + 7y2 = 15, (1, 1)

suter [353]

F'(x, y) = 14x +xydy/dx + 14ydy/dx = 0
(xy+14y)|dy/dx = -14x
dy/dx = -14x /(xy+14y)
dy/dx |(x=1,y=1) : -14(1) / (1+14) = -14/15

using
y-y1=/x-x1 = -14/15
y-1/x-1 = -14/15
15y-15 = -14x+14
15y+14x -15-14=0
14x +15y = 29

A business could not collect $5,000 that it was owed. The total owed to the business was $100,000. What fraction of the total wa

son4ous [18]

Total owed to the business = $100,000

amount that could not be collected = $5000

Fraction of total not collected

$\text{fraction not collected=}\frac{5000}{100000}=\frac{5}{100}=\frac{1}{20}$

Rewrite the equation to solve for the speed of light, c. Use rational exponents instead of roots.

Simora [160]

E=mc^2 is one of the most recognizable equations in the world. In this task, you’ll attempt to understand it better. Let’s start with what the letters mean. The letter E stands for energy, the letter m stands for mass, and the letter c stands for the speed of light. The meaning of this equation is that you can completely convert mass into energy.

c^2 = E/m
c = (E/m)^(1/2)
