F(-5)= 18
F(0)= -2
F(3)= -14
Step-by-step explanation:
F(x)= -4x -2
F(-5)= -4(-5) -2
=> 20 - 2
=> 18
F(0)= -4(0) -2
=> -2
F(3)= -4(3) - 2
=> -12 -2
=> -14
The answer is in the image
For every 8 cars there are 7 trucks
Therefore,
Cars:Truck=8:7
Answer is B)8:7
Speed=Distance/time
Here,
distance=15m
time=1sec
speed=15/1=15m/sec
Distance=Speed*time
time=15min=15*60sec=900sec
Distance travelled in 15 min=15*900=13,500m
=13500/1000 km=13.5Km
Volume of rectangular prism=length * width * height
Given,
length=3/8cm
breadth=5/8cm
height=7/8cm
therefore volume=(3/8)*(5/8)*(7/8)
=105/512 cm3
