5x² + 25x = 0
5x(x) + 5x(5) = 0
5x(x + 5) = 0
5 5
x(x + 5) = 0
x = 0 or x + 5 = 0
- 5 - 5
x = -5
Answer:
$16.43
Step-by-step explanation:
15.50 x .06 [wonder how i got .06? 6%= .06]
= .93
here's where most people mess up, the usually forget to add the tax to the original cost.
15.50 + .93
= $16.43
Let us say that y = vertical height and z =
hypotenuse <span>
dz/dt = 600
dy/dt = 0 since y (altitude) is constant
sin(θ) = 2/3
Calculating for the angle: θ = arcsin(2/3) = 0.729728 radians
sin(θ) = y/z
z sin(θ) = y
<span>We then differentiate the two sides with respect to time t:
dz/dt sin(θ)+ z cos(θ) dθ/dt = dy/dt
(600) (2/3) + (3) cos (0.729728) dθ/dt = 0
400 + [3 / cos (0.729728) ] dθ/dt = 0
400+ 4.0249 dθ/dt = 0
dθ/dt = -98.38 radians/hour
= -99.38/60 radians / min
= -1.66 radians / min = 2PI - 1.66 radians / min
<span>= 4.62 radians / min (ANSWER)</span></span></span>
