he diagram shows a circle with centre O. A and B lie on the circumference of the circle. C and A lie on a tangent to the circle. C and B lie on a tangent to the circle. Given that ∠ACB = 76°, work out ∠OBA. The diagram is not drawn accurately.

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. x^2 - 4x - 5 = 0

Acoffee shop orders at most $3,500 worth of coffee and tea. the shop needs to make a profit of at least $1,900 on the order. the possible combinations of coffee and tea for this order are given by this system of inequalities, where c = pounds of coffee and t = pounds of tea: 6c + 13t ≤ 3,500 3.50c + 4t ≥ 1,900 which graph's shaded region represents the possible combinations of coffee and tea for this order?
