The standard form of the equation that represents the number of quarters, \( q \), and the number of dimes, \( d \), that Austin has in his piggy bank is \( 5 q+2 d=270 \). Explain what the intercepts mean in terms of the context and how to find them.

Learn with an example \( \sim \) or watch a video (D) \( f=\square \) and includes the points \( (1,-5) \) and \( (3, f) \). What is the value of \( f \) ? Submit

Question 7 ( 4 points) The force exerted by the wind on a plane surface varies jointly with the square of the velocity of the wind and with the area of the plane surface. If the area of the surface is 39 square feet surface and the wind velocity is 15 miles per hour, the resulting force is 16 pounds. Find the force on a surface of 69 square feet with a velocity of 33 miles per hour. (round off your answer to 2 decimal places) Your Answer: Answer

Write the expression as a single logarithm. \( 5 \log _{5}(7 y+1)+\frac{1}{2} \log _{5}(y+3) \) \( \log _{\square}(\square) \)

Write the expression as a single logarithm. \[ \frac{1}{3} \log _{b} x+5 \log _{b} z-\log _{b} y \] \( \log _{\square}(\mathbb{)} \)
