Identify each symbol in the formula: \( f^{\prime}=f \frac{\left(v_{\text {wave }}+V_{\text {bbeserver }}\right)}{\left(V_{\text {bowe }}-V_{\text {source }}\right)} \)

What is the correct number of significant figures resulting from the following calculation? \[ 14.73 \times(9.7+3.35) \]

4) \( \frac{\csc ^{2} A-1}{\cot A \cdot \cos A}=\frac{1}{\operatorname{sen} A} \)

Jimmy decides to mow lawns to earn money. The initial cost of his electric lawnmower is \( \$ 350 \). Electricity and maintenance costs are \( \$ 6 \) per lawn. Complete parts (a) through (c). a) Formulate a function \( C(x) \) for the total cost of mowing \( x \) lawns. b) Jimmy determines that the total-profit function for the lawn mowing business is given by \( P(x)=9 x-350 \). Find a function for the total revenue from mowing \( x \) lawns. \( R(x)=15 x \) How much does Jimmy charge per lawn? \( \$ 15 \) c) How many lawns must Jimmy mow before he begins making a profit? (Round to the nearest integer as needed.)

2. What composition created the function? a. \( \sin \sqrt{x} \) b. \( 3 \sin ^{3} x \) c. \( \sin \left(\sqrt{\sin \left(3 x^{3}\right)}\right) \)

\( \int _ { 0 } ^ { 1 } \int _ { 0 } ^ { 2 \pi } \int _ { 0 } ^ { 2 n } 15 x ^ { 2 } z ^ { 2 } d z d y d x \)
