Answer:

A. Right angle -- if you multiply the slopes of 2 intersecting lines and you "-1" then the lines are perpendicular - in this case the line in quadrant 3 has a slope of "1" and the line in quadrant 4 has a slope of "-1", hence their product is "-1" and the angles formed at the intersection of the lines are right angles.

<u />

$\frac{3}{25} * 250,000 =$ Rs. 30,000

<u>2^nd businessman invested:</u>

<u />

<u /> $\frac{5}{25} * 250,000$ = Rs. 50,000

<u />

<u /> $\frac{7}{25} *250,000$ = Rs. 70,000

<u>4^th businessman invested:</u>

If they gained Rs. 50,000

(ii) The profit each one of them got is;

<u>1^st businessman got:</u>

<u />

<u /> $\frac{3}{25} * 50,000$ = Rs. 6,000

<u>2^nd businessman got:</u>

<u />

<u /> $\frac{5}{25} *50,000$ = Rs. 10,000

<u>3^rd businessman got:</u>

<u />

<u /> $\frac{7}{25} *50,000$ = Rs. 14,000

Answer:

See explanation

Step-by-step explanation:

We can see that the sequence is 90, 86,82,.......

The common difference is 86 - 90 = -4

82 - 86 = -4

Hence the sequence is arithmetic

The function is;

t(n) = 90 + (n - 1)(-4) = 90 + 4 - 4n

t(n) = 94 - 4n

Since it is AP, we have the sequence as;

90, 86, 82, 78, 74, 70, 66, 62......

He will no longer play football after the eighth quiz.

The total points earned is the sum of the first eight terms of the AP

Sn =n/2[2a + (n - 1) d]

Sn = 8/2[2(90) + (8 - 1) (-4)]

Sn = 608 points
