Chemical Company D is producing two polymers A and B as binders for paint formulation. At 10,000 g/mol polymer A has Tg 2 degree (all in Celsius), while at 11,000 g/mol polymer B has Tg 90 degree; at 15,000 g/mol polymer A has Tg 16 degree, while at 20,000 g/mol polymer B has Tg 95 degree. Now a scientist is using a formulation to mix polymer A and B at 1:1 weight ratio, and both has molecular weight of of 12,000 g/mol, please estimate the Tg of the mixture. Assume 1/Tg=w1/Tg1+w2/Tg2 and all the molecular weight is number molecular weight.

Find the distance between the parallel planes $x - 3y - 2z = 2$ and $-2x + 6y + 4z = -3$. (Hint: It is enough to pick a point P on one of the planes and find the distance between P and the other plane.) $\frac{7}{\sqrt{14}}$ $\frac{4}{\sqrt{14}}$ $\frac{5}{\sqrt{14}}$ $\frac{1}{\sqrt{56}}$ $\frac{1}{56}$

The following will help you become familiar with writing code that creates objects that are checked by the R autograder. Create three objects in R named a, b, and c respecitvely. • a: an integer vector of the integers from 1 to 100. • b: a character vector. • The first element should be "Hello, World!". • The second element should be "Welcome to STAT 385!". • c: a character vector containing the letters of the alphabet, from a to z, one letter per element, and all lowercase. The following code solves this question: a = 1:100 b = c("Hello, World!", "Welcome to STAT 385!") c = letters Copy-paste it below, then click "Save & Grade" to obtain results.

Texts: A car traveling at 31.0 km/h speeds up to 39.0 km/h in a time of 6.00 s. The same car later speeds up from 61.0 km/h to 69.0 km/h in a time of 6.00 s. Let the +𝑥 direction point in the direction the car is traveling. Calculate the magnitude 𝑎1 of the constant acceleration for the first time interval. 𝑎1= ___?__ m/s^2 Determine the distance 𝑑1 traveled by the car during the first time interval. 𝑑1= ___?__ m Calculate the magnitude 𝑎2 of the constant acceleration for the second time interval. 𝑎2= ___?___ m/s^2 Determine the distance 𝑑2 traveled by the car during the second time interval. 𝑑2= ___?__ m
