Complete question:
A wheel of radius 10 cm is turning at a rate of 5 revolutions per minute.
Calculate the angle subtended at the centre by the minor arc after 1 second.
Answer:
the angle subtended at the centre by the minor arc is 30⁰
Step-by-step explanation:
Given;
radius of the wheel, r = 10 cm = 0.1 m
angular speed of the when, ω = 5 rev/min
duration of the motion, t = 1 second
Determine the angular speed in radian per second,
After 1 second, the angular distance turned by the wheel is calculated as;
Therefore, the angle subtended at the centre by the minor arc is 30⁰
Answer:
Option (A)
Step-by-step explanation:
Parent function is given as G(x) = x²
If this function is reflected over the x-axis then the new function will be,
G'(x) = -x²
Then shifted 2 units right,
G"(x) = -(x - 2)²
Followed by the shifting of 1 unit down,
F(x) = -(x - 2)² - 1
Therefore, translated function of the given parent function will be,
F(x) = -(x - 2)² - 1
Option (A) is the answer.
For each of the numerators you multiply by 2 .
8*2=16
Answer: 16/61
Answer:
So in order to find the missing number, we must find the difference with the numbers that we were given.
Problem #1
42-30= 12 and 84-69= 15. It's possible that each difference increases by one Let's see...
30+12= 42
42+13= 55
55+14 = 69
69+15 = 84
So for 1., all you have to do is keep adding the difference and increase it by 1 each time. If you wanted to keep increasing, you would add 84+16, then 100+17, etc.
Problem #2: As for the second one, I had trouble solving it, sorry :(.
Problem #3
3. For the third problem, 27-22= 5 and 9-1=8. It looks like each difference increased by 1.
27-22 = 5
22-6 = 16
16-7 = 9
9-8= 1
