Answer:
<h2>Slope = 2</h2>
<u>Step-by-step explanation:</u>
co-ordinates = (2,2) and (-1,-4)
Slope = (y² - y¹) / (x² - x¹)
= (-4 - 2) / (-1 - 2)
= -6 / -3
= 6/3
= 2
Answer:
The maximum will be 78
Step-by-step explanation:
Answer:
RS = 4.8
OT = 3.6
From the Pythagorean Theorem we know:
OR^2 = ST^2 + OT^2
OR^2 = 4.8^2 + 3.6^2
OR ^2 = 23.04 + 12.96
OR^2 = 36
OR = 6
