### Upward Bound Math and Science

PRECALCULUS

Slope of Line

- The Slope of a Line is give by the formula
- Find the slope of the line (-1,4) and (2,-2)

Equation of Line

- The equation of line when one point on the line and slope is given by the formula
y-y1=m(x-x1)

Where

(x1,y1) are the point and m is the slope

Problem

- Find the equation of the line passing through the point (4,-3) with slope of -3

Distance between two points

- The distance between two points on the coordinate plane is given by the formula

Problem

- Find the distance between ( -1,23) and (23,-1)

Problem

- Solve Cos2q+Cosq = 0
- Hint : Cos2q = 2Cos2q-1

Problems

- A ladder leans against a building. The foot of the ladder is 6 feet from the building. The ladder reaches a height of 14 feet on the building.
- Find length of the ladder towards the nearest foot
- Find the angle between the ladder and building

Problems

- From a point on the ground 25 feet from the foot of a tree, the angle of elevation of the top of the tree is 32º. Find to the nearest foot, the height of the tree.

Problems

- The figure shown on the left is a trapezoid. Using the information given, find the area of this trapezoid to the nearest square unit.

Problems

- In the figure on the left, ABCD is a rectangle whose perimeter is 30. The length of BE is 12. Find to the nearest degree, the measure of angle E.
