4. (5 pts) Let $g(x) = \int_2^x \frac{1}{\ln t} dt$. (a) Find $g'(x)$. Determine if g is increasing or decreasing over its domain $(1, \infty)$. (b) Let $f(x) = \int_{1+x^2}^x \frac{1}{\ln t} dt$. Find $f'(x)$. (c) Use a substitution to show that $g(x) = \int_{\ln 2}^{\ln x} \frac{e^u}{u} du$. (This is a well-known function that has no elementary antiderivative.)

Q4: A Coaxial cable with connected voltage between inner and outer conductor of 500V. A Mica insulator fills the space between the two cylinders. The internal cylinder diameter is 2A, while the outer diameter is 2B, where A=5cm & B=8cm, the cable length is L=20cm. The outer cylinder is grounded while the inner is connected to Vo=500V. There is no volume charge pv=0. - Derive an expression for V, E, Q, - Calculate the capacitance C. -Plot the equipotential voltage line V=f(radius) -Plot the field intensity lines E=f(radius)

Three decimal places on parts that need decimals. The distance of fly balls hit during a baseball season are normally distributed with a mean of 250 ft and a standard deviation of 50ft. Taking samples of size 49 fly balls hit, the sample means are normally distributed with mean 250 and standard deviation 7.14 What is the probability that a sample mean of 49 fly balls is a distance less than 240 ft? -1.40 What is the 80th percentile of sample means in this case? 292.08

d) The following C program is used to send a byte of data serially through pin 3 of Port C. [1, 3 pts] i. How is the data sent out? LSB or MSB first? ii. Rewrite the program such that it sends out the data from the opposite end. #include <avr/io.h> #define serPin 3 int main(void) { unsigned char conbyte = 0x44; unsigned char regA; unsigned char x; regA = conbyte; DDRC |= (1<<serPin); for (x=0;x<8;x++) { if (regA & 0x01) PORTC |= (1<<serPin); else PORTC &= ~(1<<serPin); regA = regA >> 1; } return 0; }

The roller with the mass m and radius R can rotate without friction around the point O. Around the roller, a weightless and non-stretchable rope is thrown at the ends of which blocks of mass m1, m2 are attached. Block with mass m1 is pulled by the force P on the rough horizontal surface with coefficient of friction. Calculate the angular acceleration of the roller. Given: m, m1, m2, R, P = ?
