Hello,
To solve we need to factor y^2-2y-35:
(y-7)(y+5)=0
Now solve for :
(When will (y-7)(y+5)equal zero?)
When y-7=0 or y+5=0
Solve for the 2 equations above and;
y= 7,-5
Hope this helps, have a great day!
Using Pythagorean theorem.
16^2 + (RT)^2 = 20^2
256 + (RT)^2 = 400
(RT)^2 = 144
RT = 12
Using altitude theorem to find ST:
16/12= 12/ST
16ST = 144
ST = 9
Using Pythagorean theorem again:
12^2 + 9^2 = SR^2
144 + 81 = SR^2
225 = SR^2
SR= 15
Final answer: SR= 15
Hope this helps!
Answer:
IQR is 3.5
Step-by-step explanation:
<u>Step 1: Organize the numbers in numerical order</u>
0,0,2,2,3,4,6,8
<u>Step 2: Break the set up into quartiles (4 parts)</u>
0 0 | 2 2 | 3 4 | 6 8
<u>Step 3: Find the average of each quartile</u>
0 | 2 | 3.5 | 7
<u>Step 4: Find the IQR (Q3-Q1)</u>
3.5-0=3.5
Therefore, the IQR is 3.5
