Answer:
Step-by-step explanation:
a true
b false
We can represent the base as z and the height as 2z+6. We are going to use the formula A=1/2*b*h and solve for z
180=1/2*z*(2z+6)
360=2z^2+6z
0=2z^2+6z-360
0=2(z^2+3z-180)
0=(z+15)(z-12)
So z=-15 and 12 but it must be positive so then the base is equal to 12
When we plug this into 2z+6 we get 30 for the height
2(12)+6=30
Hope this helps
Answer:
v= s/t = sqrt(360^2+480^2) x 0.3048/0.5 = 365.76(m/s)
Step-by-step explanation:
s =sqrt(360^2+480^2)
s-ft-to-m = s*0.3048
t = 0.5
