Write the expression as a sum and/or difference of logarithms. Express powers as factors. \( \ln \left(x^{2} \sqrt{5-x}\right), 0

The regression line for \( Y \) vs \( X \) is given by \( Y=0.82 X+59.1 \). The standard deviations for \( X \) and \( Y \) are 1.5 and 2.2 respectively. Suppose now we construct a regression line that uses \( Y \) to predict \( X \). The predicted average increase of \( X \) when \( Y \) is increased by 1 unit is (Give your answer correct to 2 decimal places.)

An unknown compound has the following chemical formula: where \( x \) stands for a whole number. Measurements also show that a certain sample of the unknown compound contains 8.2 mol of chlorine and 1.65 mol of phosphorus. Write the complete chemical formula for the unknown compound.

In Diagram, PQR is an arc of a circle with centre T. PRT is an equilateral triangle and RST is a semicircle with centre 0 . Given \( R T=5.6 \mathrm{~cm} \), find the nerimeter. in cm. of the whole diagram.

Find the function rule for \( g(x) \). The function \( f(x)=x^{2} \). The graph of \( g(x) \) is \( f(x) \) translated to the right 7 units and up 3 units. What is the function rule for \( g(x)^{\text {? }} \) \[ g(x)=(x+3)^{2}-7 \] o \( g(x)=(x-7)^{2}+3 \) \( g(x)=(x+7)^{2}-3 \) \( g(x)=(x-3)^{2}+7 \)
