Answer:
the duration of this event is 4 hours
Step-by-step explanation:
This function is a quadratic one
let Δ be the dicriminant :
- a = -16
- b = 48
- c= 64
- Δ = 48²-4*(-16)*64 = 6400
so there are two values that satisfy -16t²+48t+64 = 0 x and y
- x= (-48+80)/-16*2 = -1
- y= (-48-80)/-16*2= 4
x<0 so w won't take it since time is a positive value here
so t = y = 4h
The postulate that justifies the statement below the given diagram is the: angle addition postulate.
<h3>What is the Angle Addition Postulate?</h3>
According to the angle addition postulate, the sum of the measures of two angles that make up a bigger equals the measure of the bigger angle.
Two small angles, MRO and MRS add up to give the bigger angle, SRO, which contains both angles.
Therefore, the postulate that justifies, m∠MRO + ∠MRS = m∠SRO, is: angle addition postulate.

Answer:
the answer is a log 3 +3log2
This is actually pretty easy. Since we want lines, we can eliminate the bottom 2. The symbol for perpendicular is an upside down T so it is B
Answer:
(x+6)(x+3)
Step-by-step explanation:
The factors of 18 that sum to 9 are 6 and 3, so:
(x+6)(x+3)
