Since the first term is -5 and the difference is 6 so a2=1,a3=7,a4=13,a5=19. Hope that helped. if you have any questions regarding how I got the values, feel free to ask. :')
800/85 = 9.411764705882353 inches
ans = 9.411764705882353 inches
Answer:
9.9inches
Step-by-step explanation:
From the attachment, the opposite side is debited as "x" while the Hypotenuse is 10.9inches, we can find the third side by using trigonometry
From trigonometry, Sin(x)= opposite/Hypotenuse
Sin(65)=X/10.9
X= Sin(65) ×10.9
X=0.9063×10.9
=9.8688
Hence the third side of the triangle is approximately 9.9inches

1. v=d/t=7.5/1.5=5 km/h
2. v=d/t=(v1*t1+v2*t2+v3*t3)/(v1+v2+v3)=(15*10+20*10+25*5)/(10+10+5)=
=(150+200+125)/25=475/25=19 m/s
