- Pentagon
The signboard has the shape of a pentagon ABCDE, in which the line BC is perpendicular to the line AB and EA is perpendicular to the line AB. Point P is the heel of the vertical starting from point D on line line AB. | AP | = | PB |, | BC | = | EA | = 6dm - Peter's rectangle
Peter had a rectangle 2 cm wide and of unknown length. The line had a 2 cm rectangle whose length was equal to the perimeter of Peter's rectangle. When they put the rectangles together with their widths, they got a new rectangle with a circumference of 63 - Direct proportion
y varies directly as x and y=32 when x=4. Find the constant of variation. - Linear temp change

What is the equation of the line whose x - intercept is - 3 and y - intercept is -4? Find coefficients A, B, C in normal line equation: Ax + By = C - Two places
The actual distance of the two places is 105 km. Find the scale of the map on which this distance is marked by a line 1.2 dm long. - Two midpoints
Point A is on a number line halfway between -17 and 5 . Point B is halfway between Point A and 0. What integer does Point B represent? - The satellite
The satellite orbiting the Earth at an altitude of 800 km has a speed of 7.46 km/s. For how long would it have to move from the start to the orbit to reach this speed if it evenly accelerated its motion in a straight line? What is the acceleration of sate - RS ABS
Find the distance between points R and S on a number line, with coordinates -4 and -7, respectively. - The castle
The castle moat is shown on the map by a line 2 cm long. In fact, the moat is 500 meters long. Determine the scale of the map. - Touch circle
Point A has a distance IA, kl = 10 cm from a circle k with radius r = 4 cm and center S. Calculate: a) the distance of point A from the point of contact T if the tangent to the circle is drawn from point A b) the distance of the contact point T from the l - Straight-line depreciation
Olsen Inc. Purchased a $580,000 machine to manufacture a specialty tap for electrical equipment. The tap is in high demand and Olsen can sell all that it could manufacture for the next 10 years. To encourage capital investments, the government exempts tax - Approximation of tangent fx
