Hi,
So this might be telling you the letters of the angles eg: an angle that has the letter next to it like PKS is an acute angle so you put that in the first column and find an obtuse and right angle and put all the letters of the angle in that column and then ask me what to do next when you have done !
Hope this helps you :)
Bank 1:
$5550 for 5 years with interest 2.3% paid twice a year.
5550 x 1.023^(5 x 2) = 5550 x 1.023^10 = $6967.06 (to 2 decimal places)
(amount of money) x (multiplier - a bit like saying x (100% + 02.3%) because it's increasing the original 100% by 2.3%)^(The time the money is in the account for (years) x how many times a year interest is paid)
6967.06 -5550 = $1417.06 added during the 5 years
bank 2:
$5550 for 5 years with interest 2.2% paid 12 times a year.
5550 x 1.022^(5 x 12) = 5550 x 1.022^60 = $20480.79
20480.79 -5550 = $14930.79 added during the 5 years
comparison:
(bank 1 = + $1417.06 ) < (bank 2 = + $14930.79 )
therefore bank 2 offers the most interest.
hope this helps
Answer:
<h2>735 J</h2>
Step-by-step explanation:
The potential energy of a body can be found by using the formula
PE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
From the question we have
PE = 15 × 9.8 × 5
We have the final answer as
<h3>735 J</h3>

So the test he scored lowest is 69 so discard this score and put x for it
average=numbers added together then summ is divided by number of numbers exg
average of 2 and 4 and 5 is 2+4+5=11 then 3 numbers so 11/3 is average or aprox 3 and 2/3 so
![\frac{76+84+x+74+91}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B76%2B84%2Bx%2B74%2B91%7D%7B5%7D%20)
=average
he wants his new average to be at least 82 so
![\frac{76+84+x+74+91}{5} \geq 82](https://tex.z-dn.net/?f=%20%5Cfrac%7B76%2B84%2Bx%2B74%2B91%7D%7B5%7D%20%5Cgeq%2082%20)
solve
![\frac{76+84+x+74+91}{5} \geq 82](https://tex.z-dn.net/?f=%20%5Cfrac%7B76%2B84%2Bx%2B74%2B91%7D%7B5%7D%20%5Cgeq%2082%20)
treat as equation
first add like terms in top
![\frac{325+x}{5} \geq 82](https://tex.z-dn.net/?f=%20%5Cfrac%7B325%2Bx%7D%7B5%7D%20%5Cgeq%2082%20)
multiply both sides by 5 to clear fraction
325+x
![\geq](https://tex.z-dn.net/?f=%20%5Cgeq%20)
410
subtract 325 from both sides
x
![\geq](https://tex.z-dn.net/?f=%20%5Cgeq%20)
85
he must get
![\geq](https://tex.z-dn.net/?f=%20%5Cgeq%20)
85 to get an average of at least 82
