Question 9 of 12, Step 1 of 1 Factor the given trinomial. If the trinomial cannot be factored, indicate "Not Factorable". \[ x^{2}+8 x+15 \] Answer How to enter your answer (opens in new window) Selecting a radio button will replace the entered answer value(5) with the radio button value. If the radio button is not selected, the entered answer is used. Keyboard

Outside temperature over a day can be modelled using a sine or cosine function. Suppose you know the high temperature for the day is 62 degrees and the low temperature of 42 degrees occurs at 7 AM. Assuming \( t \) is the number of hours since midnight, find an equation for the temperature, \( D \), in terms of \( t \). \( D(t)= \)

In the xy-plane, the line determined by the points \( (3, m) \) and \( (m, 12) \) passes through the origin. Which of the following could be the value of \( m \) ? A. -6 B. 9 C. 1 D. 0

b.) \( \sqrt{28 x \cdot x}= \)

b) \( \frac{\sqrt{1,3}\left(\frac{5}{4}+\frac{1}{3}\right)}{\left(\frac{6}{5}\right)^{-1}}=\frac{2 x-0,4}{x+1,2} \)

Write the complex number \( \frac{3+2 i}{1-4 i} \) in the form \( a+b i \)
