Answer:
B) 0.0073 mm/s
Step-by-step explanation:
The rate of change of area is the product of the circumference and the rate of change of radius:
dA/dt = C·dr/dt
dr/dt = (dA/dt)/C
Of course, C = 2πr, so ...
dr/dt = (7 mm²/s)(2π·152 mm) ≈ 7/955.04 mm/s ≈ 0.0073 mm/s

Step-by-step explanation:
Hi there!
Linear equations are typically organized in slope-intercept form:
where <em>m</em> is the slope and <em>b</em> is the y-intercept (the value of y when the line crosses the y-axis)
Given that the slope is 3, we can plug this into y=mx+b as <em>m</em>:
Now, to solve for <em>b</em>, simply plug in the given point:

Therefore, the y-intercept is 5. Plug this back into the equation:
I hope this helps!
Answer and explanation:
Stellar is a Brazilian cryptocurrency that is used to facilitate low cost and flexible payment. It was renamed lumens and is denoted XLM.
One stellar lumen is currently equal to $0.219096
For the purpose of the question and since it does not specify exchange rates for each bank, let's assume:
Bank A= 0.219097 to 1 US dollar
Bank B= 0.219099 to 1 US dollar
Using Bank A to exchange $1700 for stellars= $1700*0.219097= 372.464 stellars
Using Bank B to exchange $1700 for stellars= $1700*0.229042= 389.3714 stellars
From the above, we can see that Bank B has a better exchange rate as it is cheaper than Bank A(gives more stellar) . She should therefore use Bank B for her exchange.
