If a triangle is a right triangle, then the triangle has one \( 90^{\circ} \) angle. \( \triangle A B C \) is a right triangle. Conclusion: \( \triangle A B C \) has one \( 90^{\circ} \) angle. Conclusion: \( \triangle A B C \) has one \( 180^{\circ} \) angle. Conclusion: \( \triangle A B C \) has one \( 0^{\circ} \) angle. Not possible: separate conclusions

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

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. \( C(x)=350+6 x \) 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? \( \$ \square \)
