1 answer:

Answer:

Step-by-step explanation:

a)

The mistaken assumption is that Apple spends "far less" on Research and Development than any of its rivals.

b)

The assumption is incorrect because it took cognizance of the percentage used, and not the actual money spent. In truth, Apple generates far more income than the other two rivals. With Apple generating over $100bn in the said time span, and Google generating $37bn. At the end of the day, Apple spends $2.1bn on Research and Development, while Google spends $5.3bn on the same. This is quite close than the quoted distance of 14% - 2%

c)

Yes, I think so. But only when the 3 companies generate almost the same revenue.

Write the equation of the line that is perpendicular to the line y = 2x + 2 and passes through the point (6, 3).

Mama L [17]

For this case we have that by definition, the equation of the line in a slope-intersection form is given by:

$y = mx + b$

Where:

m: It's the slope

b: It is the cut-off point with the y axis

We have the following equation:

$y = 2x + 2$

Thus, the slope is $m_ {1} = 2$

By definition, if two lines are perpendicular then the product of the slopes is -1.

$m_ {1} * m_ {2} = - 1$

We find $m_ {2}:$

$m_ {2} = \frac {-1} {m_ {1}}\\m_ {2} = \frac {-1} {2}$

Thus, the equation of the line is:

$y = - \frac {1} {2} x + b$

We substitute the given point to find "b":

$3 = - \frac {1} {2} 6 + b\\3 = -3 + b\\b = 6$

Thus, the equation of a line perpendicular to the given line and passing through the given point is:

$y = - \frac {1} {2} x + 6$

Answer:

$y = - \frac {1} {2} x + 6$

A customer buys 17.01 in gas and requests one five dollar [$5] lottery ticket, two one dollar [$1] lottery tickets, and one [$3]

Alik [6]

17.01+5+2+3= 27.01 (total expense)
100-27.01= 72.99 (change)
5+2= 7 (total winnings)
72.99+7.00= 79.99 (total change).

the oval track below is formed by a straight section on each side and a semicircle at each end. what is the approximate distance

nikklg [1K]

Answer:

1040

Step-by-step explanation:

Circumference of the Circle: 439.82

Add that to the length of the rectangle time two: 439.82+(300x2)

That will give you the perimeter around the entire track:

439.82+(300x2)

439.82+600

1039.82

Rounded that is: 1040
