Use the Pythagorean theorem:
Answer: C. 7.5
Answer:
Step-by-step explanation:
Given function:
where:
- h = height (in feet)
- t = times (in seconds)
Rewrite in the form
The quickest way to do this is to expand and compare coefficients with the original function.
Comparing coefficients with
Therefore, substituting the found values into the equation:
Answer:
3 AND 5
Step-by-step explanation:
LET THE TWO NUMBERS BE X AND Y
THEN
X + Y = 8 …….1
X – Y = 2 …… 2
WE SOLVE SIMULTANOUSLY
SUBTRACTNG EQATION 2 FROM 1
X – X + Y – (-Y) = 8 – 2
Y + Y = 6
2Y = 6
DIVIDING EACH TERM BY 2
2Y/2 = 6/2
Y = 3
THEN PUTTING Y = 3 IN EQUATION 1
X + 3 = 8
X = 8 – 3
X = 5
