Answer:
PS = 7
k = 9
Step-by-step explanation:
RS = PQ Given
3x - 7 = x - 1 Substitute algebraic terms. Subtract x from both sides
3x-x - 7 = x - 1 - x Combine
2x - 7 = - 1 Add 7 to both sides.
2x - 7+7 = -1+7 Combine
2x = 6 Divide by 2
2x/2 = 6/2
x = 3
Length of PS = x - 1 + x + 3x - 7
Length of PS = 5x - 8
Length of PS = 5*3 - 8
Length of PS = 7
=========================
f(x) = k - x^2
x = 2
f(x) = 5 is the given point
5 = k - x^2 Substitute for x^2
5 = k - 2^2 Expand
5 = k - 4 Add 4 to both sides.
5+4=k-4+4 Combine
k = 9
Answer:
True
Step-by-step explanation:
We have the serie:
To test whether the series converges or diverges first we must find the rule of the series
Note that:
Then we can write the series as:
Then:
The series that have the form:
are known as "p-series". This type of series converges whenever 
.
In this case, 
and 
. Then the series converges
I just want points idek the answer....hehe
You have to add the ratio, which is 1:3:5 and 1+3+5= 9. Then you must do £77.40 divided by 9. This gives you £8.6. So 1 part is £8.60, also how much Paul got. To find out Brian, you must do 5 multiplied by £8.60 which gives you £43. Then, to get the difference, you must do £43 take away £8.60, giving you £34.40. Your final answer will be £34.40. I hope this helped!
