Answer:
c]
Step-by-step explanation:
We know
In a function
x represents the input and y represents output
So
x is time
So
f(30) represents distance traveled in 30mins
Answer:
89.8 feet
Step-by-step explanation:
In ΔBCD, the measure of ∠D=90°, the measure of ∠B=75°, and DB = 93 feet. Find the length of BC to the nearest tenth of a foot.
We would solve the above question using Sine rule
The formula is given as:
DB/sin D = BC/sin B
93/sin 90 = BC/sin 75
We cross multiply
sin 90 × BC = 93 × sin 75
BC = 93 × sin 75/sin 90
BC = 89.83 feet
Approximately BC = 89.8 feet
Answer:
x=3a+19/2a; a inequality 0
Step-by-step explanation:
2(ax+3)/2=25/2+3a/2
ax+3=25+3a/2
ax+3-3=25+3a/2-3
ax=25+3a/2-3
ax/a=25+3a/2/a-3/a; a inequality 0
x=3a+19/2a; a inequality 0
