Two blocks are connected to point A which is supported by two ropes as shown. One rope connects point A (3.7,1.3) to point B (6.3,5.7). The second rope is at an angle $\theta = 64^\circ$ from the ceiling. The mass of block 1, $m_1 = 30$ kg, and the mass of block 2, $m_2 = 124$ kg. Resolve the tension holding both blocks into force in each rope AB and AC.

3. The points P and Q are moving along the graph of a twice-differentiable function $y = f(x)$ in the \\ xy-plane in such a way that their coordinates are differentiable functions of time $t$, and the tangent line \\ to the graph at the point P intersects the graph also at the point Q at all times. (Assume that the \\ coordinates are measured in meters and the time is measured in seconds.) \\ Find $f''(2)$ if \\ ? the $x$-coordinate of Q is $-1$ and decreasing at a rate of 3 m/s when the $x$-coordinate of P is 2 \\ and increasing at a rate of 4 m/s, \\ ? $y = 9x - 8$ is an equation for the tangent line to the graph of $f$ at the point with $x = 2$, and \\ ? $y = -6x - 23$ is an equation for the tangent line to the graph of $f$ at the point with $x = -1$.

Calculate the directional derivative of $f(x, y) = \cos^{-1}(xy)$ in the direction of $\mathbf{v} = -3\mathbf{i} - 2\mathbf{j}$ at the point $P = (0.5, 0.5)$. Remember to normalize the direction vector. $D_\mathbf{v}f(0.5, 0.5) = $

Suppose a professor wants to know how the time spent studying affects student performance on microeconomic exams. She collects a random sample of observational data on students in 2019. Her data contain the number of hours students study per week and their final microeconomics exam scores. If she estimates the following bivariate model using OLS, will her estimates of beta0 and beta1 be unbiased? Why or why not? examscore_i = beta0 + beta1 * hrsstudy_i + u_i
