Answer:
850,000
Step-by-step explanation:
The ten thousand place is the second digit to the left of the comma. In this case, the number is 5. When rounding, you look at the number to the right of it. If the number is five or greater, you round up. If the number is four or less, you round down. The number next to 5 is 4. So you round down to 850,000 instead of 860,000.
Answer:
£37
Step-by-step explanation:
£1.90x20
= £38
£75-£38
=£37
The 400th term is 425.There are floor(√400) = 20 squares in the range 1..400, so the 400th term will be at least 420. There are floor(∛420) = 7 cubes in the range 1..400, so the 400th term may be as high as 427. However, there are
![\lfloor\sqrt[6]{427}\rfloor=2](https://tex.z-dn.net/?f=%5Clfloor%5Csqrt%5B6%5D%7B427%7D%5Crfloor%3D2)
numbers that are both squares and cubes. Consequently, the 400th term will be 427-2 =
425.
Answer:
-90° = 3π/2 radians
Step-by-step explanation:
Keep in mind that -90° represents a 90° clockwise rotation from the positive x-axis. This is the same as a 360°-90°=270° counter-clockwise rotation from the positive x-axis.
To convert from degrees to radians, we simply multiply the degrees by π/180 radians. So, the answer is (270)(π/180)=(270π/180)=3π/2 radians
