- Penny free fall
A man drops a penny from the top of a 500 m tall building. After t seconds, the penny has fallen a distance of s meters, where s(t)=500-5t². Determine the average velocity between 1 s and 5 s. - The kitchen
The kitchen has the shape of a square with a side of 5 m. We place linoleum on the floor, the price of which is 450 CZK per 1 m². The glue costs 750 CZK. How much do we pay in total? - Grass seed calculation
How many g of grass seed do we have to buy in the eight-square garden with a side of 20 m if we need 100 g of seed per 8 m²? - Extending square garden
Mrs. Petrová's garden had a square shape with a side length of 15 m. After its enlargement by 64 m² (square), it became a square again. How many meters has the length of each side of the garden been extended? - Half of halves
We cut half of the square off, then half of the rest, etc. Five cuts we made in this way. What part of the area of the original square is the area of the cut part? - Two brothers
The two brothers were to be divided according to the will of land at an area of 1ha 86a 30 m² in a ratio of 5:4. How many will everyone get? - Rifle recoil
A projectile weighing m1 = 0.01 kg is fired at a velocity v1 = 800 m/s from a rifle weighing m² = 4 kilograms. - Rope slack
Between two streets, 20 m away, give the lamp in the middle and hang 60 cm below the taut rope. Can it be done with a 20.5 meters rope? - Quadratic function
It is given a quadratic function y = -4x²+5x+c with an unknown coefficient c. Determine the smallest integer c for which the graph of f intersects the x-axis at two different points. - Rectangles
How many rectangles with an area of 8855 cm² have sides that are natural numbers? - Booth perimeter calculation
The sales stand floor plan consists of squares and has an area of 48 m². What is the perimeter of these booths? a. 34 m b. 36 m c. 40 m d. 44 m - Square area increase
The area of the square is 36 cm². What will be the area of the square if we increase the length of a side by 25%? - The cost 4
The cost to tile a floor that measures 7 x 6 square feet is $ 2,100. How much will tile a floor measuring 11 x 13 square feet cost? - Chi square
A phone battery manufacturer claims that his battery lives are approximately normally distributed with a standard deviation equal to 0.9 years. Suppose a random sample of 10 of these batteries has a standard deviation of 1.2 years. Do you think that the s - Corresponding
Suppose that the country has had the following inflation rates over the past 14 years: 6.0, 6.7, 10.4, 11.9, 7.2, 3.5, 8.4, 7.5, 2.8, 4.3, 1.9, 3.9, 0.9, 0.7. Use the χ² goodness-of-fit test to determine whether the random variable ξ corresponding to this - Square side
If we enlarge the square side a = 5 m, its area will increase by 10,25%. How much percent will the side of the square increase? How many percent will it increase the circumference of the square? - Car braking calculation
The car starts to brake with an acceleration of -6.5 m/s² and stops on the track at 45 m. What were the initial speed and braking time? - The land
The land in the shape of a square has 9 ha. How big a side will the land have at a scale of 1:5000? - Car acceleration distance
How far must a car travel to reach a speed of 72 km per hour if it starts from rest in a uniformly accelerated motion with an acceleration of 0.2 meters per second²? - Water tube pressure
Water flows in a horizontal tube at a speed of 2.24 m/s and has a pressure of 0.1 MPa. How fast does the water flow in the narrowed part of the tube if its pressure is 0.09 MPa?
