There were 25 questions. 21/25 x 100 = 84%
Answer should be 40 if I did the math right
You solve by with by altitude! Hope it helps
Answer:
p(x)=x^4+9x^3-9x+2
p(-3)=(-3)⁴+9(-3)³-9×(-3)+2=81-243+27+2=-133 is you answer
Answer:
1. 2x
2. v(t) =2
3. 24mph
Step-by-step explanation:
1. W(t) = x^2 -3
dw/dt = 2x dx/dt
2. v(t) =2
Take the derivative to get the acceleration
dv/dt = 0
The choice you picked has 0 velocity so it is not in motion
3. To find the velocity
x(7) - x(5)
