Answer:
54 minutes
Step-by-step explanation:
We can write a proportion to solve this problem. Put the number of pages over the minutes
27 pages 324 pages
-------------- = ---------------
4.5 minutes x minutes
Using cross products
27 * x = 324 * 4.5
27x = 1458
Divide each side by 27
27x/27 = 1458/27
x =54
Answer: (-3,-3)
Step-by-step explanation:
(3+-9)/2=-3
(1+-7)/2=-3
1 / cos^2 O - 3 / cos O - 2 = 0
1 - 3 cos O - 2 cos^2 O = 0
2 cos^2 O + 3 cos O - 1 = 0
cos O = 0.2807 , -1.78 ( -1.78 cannot be a solution)
O = 74 degrees (from 0.2807) another solution is 360-74 = 286 degrees
Its D
Answer:
see explanation
Step-by-step explanation:
There is a common difference d in the values, that is
9 - 5 = 13 - 9 = 17 - 13 = 21- 17 = 4
To obtain a term in the sequence add 4 to the previous term, thus
t₉ = t₈ + 4 → C
(b)
Given the n th term formula 3n - 8
To find any term, substitute the term position n into the formula
(i) first term (n = 1), then
3(1) - 8 = 3 - 8 = - 5
(ii) tenth term (n = 10, then
3(10) - 8 = 30 - 8 = 22
(iii) 100 th term ( n = 100), then
3(100) - 8 = 300 - 8 = 292
