6. A little girl's tricycle has a front wheel whose diameter is 20 inches and rear wheels whose diameters are 8 inches. As she rides down the sidewalk one afternoon, she is pedaling the front wheel at 30 revolutions per minute. How many revolutions per second are the rear wheels making?
The nurse explains to Mr. Perry that the peritoneal fluid was sent to the lab for culture and sensitivity testing. Mr. Perry is curious about the test and asks the nurse what that involves. The nurse explains that culture and sensitivity testing is completed for which of the following reasons? Identifies the correct pathogen responsible for the infection and then an appropriate drug is selected to control the microorganism in the culture Screens for an infection, an inflammation, or a condition that affects the white blood cell (WBC) count Determines the range of bacteria against which an anti-infective is effective Determines the ability of pathogens to adapt to an anti-infective to produce cells that are no longer affected by a particular drug

Line Tangent to a Curve at a Point. PART 1. Using the definition of derivative of a function at a point, $f'(a) = \lim_{h \to 0} \frac{f(a+h) - f(a)}{h}$, find the slope of the tangent to the curve at the given point $f(x) = \sqrt{x} + 1$; $a = 121$ The slope of the tangent to the curve at $a = 121$ is Note: Enter a numerical value for the slope. PART 2. The equation of the line tangent to the curve at $a = 121$ is Note: Type answer in form $y = mx + b$.
Sec. Ex. 3 - Real Part Complex Time-Varying Current 1 out of 5 attempts Let the real part of the complex time-varying current $i(t)$ be $Re[i(t)]$. Find $Re[i_A(0.6)]$ if $i_A(t) = K_A e^{S_A t}$, where $K_A = 8 - j4$ and $S_A = 3 + j14$. Round intermediate calculations and final answer to two decimal places. $Re[i_A(0.6)] \approx$
Problem 2 (25 points): Given the source voltage $V_s(t) = A \sin(2\omega t)$, the resistance R and capacitor C derive the differential equation satisfied by the output voltage V(t) of the \"low pass filter\" presented in the figure. Assuming the initial condition V(0) = 0 solve the differential equation and find the output voltage V(t). Based on this solution explain why this circuit is called a \"low pass\" filter?
