Answer:
Step-by-step explanation:
Formula for area of a triangle:
Height x Base /2
Base (b) = h +4
Height = h
h + 4 x h /2 = 30cm
=> h +4 x h = 60
=> h+4h =60
=> 5h = 60
=> h = 12
Height = 12
Base = 12 +4 = 16
Roughly 88-89 citizens died in automobile accidents per day.
32,300 is the number of people in one year, so in order to find the daily count we need to divide that number by the number of days in a year, 365.
32,300 ÷ 35 ≈ 88.5
This means that roughly 88-89 citizens died in automobile accidents per day.
The volume is 1562.4 cm^3
V = (173.6 cm^2)(9cm)
= 1562.4 cm^3
5x + 10y = 50
x + y = 8
x = 8 - y
5*(8-y) + 10y = 50
40 - 5y + 10y = 50
10y - 5y = 50 - 40
5y = 10
y = 2
x + y = 8
x + 2 = 8
x = 8 - 2
x = 6

Answer:
Step-by-step explanation:
when x=0,sin x=0
when x=30° or π/6
sinx=1/2=0.5
when x=45° or π/4
sin x=√2/2≈1.414/2≈0.707
when x=60° or π/3
sinx=√3/2≈1.732/2≈0.866
when x=90° or π/2
sin x=1
when x=120° 2π/3
sin 120=sin (180-60)=sin 60 ≈0.866
when x=135° or 3π/4
sin 135=sin (180-45)=sin 45≈0.707
when x=150° or 5π/6
sin 150=sin (180-30)=sin 30=0.5
when x=180 or π
sin 180=sin(180-0)=sin 0=0
when x=210° or 7π/6
sin 210=sin (180+30)=-sin 30=-0.5
when x=225° or 5π/4
sin x=sin (180+45)=-sin 45≈-0.707
when x=240° or 4π/3
sin 240=sin (180+60)=-sin 60≈ -0.866
when x=270° or 3π/2
sin 270=sin (180+90)=-sin 90=-1
when x=300° or 5π/3
sin 300=sin(360-60)=-sin 60≈ -0.866
when x=315°or 7π/4
sin 315=sin (360-45)= -sin 45≈ -0.707
when x=330° or 13π/6
sin 330=sin (360-30)= -sin 30 =-0.5
when x=360 or 2π
sin (360)=sin (360+0)=sin 0=0
plot all these points on the graph,you get the reqd. graph.
you see it starts on (0,0)
