In the evening, Zuzana measured the air temperature at -2.4 °C. In the morning, she measured the temperature three times higher. What temperature did Zuzana measure in the morning? - Number axis point
On the number axis, point P is the image of the number -2.54, and point Q is the image of the number 10.71. Find which number is the point R such that Q is the center of the line PR. - Difference in temperatures The temperature in the number line shows minus 15 degrees celsius and 8-degree celsius. What is the difference between the temperatures?
- Integer Find the integer whose distance on the numerical axis from number 1 is two times smaller than the distance from number 6.
- Equation of the circle
Find the equation of the circle with the center at (1,20), which touches the line 8x+5y-19=0 - Function value calculation
1) The function f is given: y = I 2-x I + 2. Determine the values of the function in points, i.e., f(-2), f (0), f (1), f (4,8). - Clock angle
Calculate the magnitude of the angle formed by the lines p and q, which connect 1, 6 (line p), and 5, 8 (line q) on the clock face. - Angle between line and plane
Find the angle between the line given parametrically by x = 5 + t y = 1 + 3t z = -2t t ∈ R and the plane given by the equation 2x-y + 3z-4 = 0. - Two chords
In a circle with a radius of 8.5 cm, two parallel chords are constructed, the lengths of which are 9 cm and 12 cm. Find the distance of the chords in a circle. - Coordinate axes
