The first one u circled is a single rotation
Answer:
Step-by-step explanation:
Given
Required
Gaps: -2( )-2( )=8
<em>Fill in in the gaps</em>
The are numerous solutions to this.
One of them is:
Assume y = 0.
So, we have:
Divide through by -2
Fill in the gaps with these values of x and y respectively:
Hence; one solution is:

Answer:</h3>
B) 6 hours
<h3>
Step-by-step explanation:</h3>
Let h represent the total trip time. Then h/2 is the time spent traveling at each speed. The distance covered is ...
... distance = speed · time
The sum of the distances in each mode is the total distance.
... 1020 = 55·h/2 +285·h/2
... 2040 = h·(55+285) . . . . multiply by 2
... 2040/340 = h = 6 . . . . . . . divide by the coefficient of h
The trip took a total of 6 hours.
Answer:
4
Step-by-step explanation:
The sum of n terms of a geometric series with first term a1 and common ratio r is given by ...
Sn = a1·(r^n -1)/(r -1)
for r=5 and n=6, this becomes ...
15624 = a1·(5^6 -1)/(5 -1) = a1·(15624/4)
Then we have ...
1 = a1/4 . . . . . divide by 15624
4 = a1 . . . . . . multiply by 4
The first term of the series is 4.
By dividing 5 by 6 you will find the answer which is 0.83333333
(Tip: fraction is just division, divide the dividend [top] with the divisor[bottom](☞ ͡° ͜ʖ ͡°)☞)
