Answer:

Step-by-step explanation:

sec (thita) = squrt (5)

squaring on both sides:

sec^2 (thita) = 5 - equation 1

1 + tan^2 (thita) = 5

tan^2 (thita) = 4

tan (thita) = 2.

= tan (thita) - squrt(5)sin(thita)

= 2 - squrt(5) x 2/ squrt(5)

= 0

from eqn - 1

sec(thita) = squrt(5)

cos(thita) = 1/ squrt(5)

sin(thita) = squrt ( 1- 1/(squrt (5))^2)

sin(thita) = 2/ squrt(5) .

(-3, 3) (2,0)
slope = (3-0)/(-3-2) = -3/5

3)

Hi guys, I need help to solve this. I can’t understand how the percentage is calculated in (a) and (b) and how the rent is calcu

Answers :

(A) 18.33%
(B) 21.65%
(C) about 173.33
(D) i really have no way of finding the angles for you, you could try to find them yourself; or maybe just leave it blank?

<h3>OK, so judging from the bar shown : </h3>

It looks like <u>Rent</u> takes up 1/3 of the space so 33.33..%

It also looks like <u>Loan Repayment</u> + <u>Savings</u> is another 33.33..% but Savings is slightly larger than Loan Repayment so you could just estimate Savings to be 55% and LR to be 45% of the 1/3 space.

55% of 33.33.. = 18.33%

45% of 33.33.. = 14.99%

LR looks equal to <u>Entertainment</u> making it another <u>14.99.</u>

It also looks like Entertainment + Electricity + Groceries = the last 33.33..%

And since we know <u>Entertainment</u> = 14.99 / 45% of 33.33..

Making <u>Electricity and Water</u> <em>ABOUT</em> 35% of 33.33... which is <u>11.66</u>

And Groceries is somehow 20% of 33.33 = <u>6.66</u>

Rent = 33.33..%
Savings = 18.33%
Loan Repayment 14.99%
Entertainment 14.99%
Electricity and Water 11.66%
Groceries = 6.66%

<h3>All of these added together equal <u><em>ABOUT</em></u> 100%</h3>

There is a correlation between height and speed of the serve

<h3>How to interpret the player statistics?</h3>

From the question, we understand that:

The taller a player, the faster the serve

This means that:

Height implies speed

In other words, there is correlation between the height and the speed of the service
