Answer:
I think the dad is 54 and the son is 20
In 6 years he would be 60 which is three times 20
Answer: The term to term rule is an Arithmetic progression for the two question. B) 1Oth term for the first is 30 and for the second series is 59
Step-by-step explanation:
4.1) 3 6 9 12 15
For the sequence above, we can see that the next term is gotten by addition of 3 with the previous term and so It is an Arithmetic progression.
Having in mind the nth term of an AP as Tn = a + (n - 1)d.
where a is the first term =3
And d common difference =3(6-3,9-6,12-9)
10th term=
T10 = 3+ (10 - 1)3.
T10 = 3+ (9)3.
T10 = 3+ 27.
T10 =30
4.2) 5 11 17 23 29
For the sequence above, we can see that the next term is gotten by addition of 6 with the previous term and so It is an Arithmetic progression.
Having in mind the nth term of an AP as Tn = a + (n - 1)d.
where a is the first term =5
And d common difference =6 (11-5, 17-11,23-17)
10th term=
T10 = 5+ (10 - 1)6.
T10 = 5+ (9)6.
T10 = 5+ 54.
T10 =59
Answer:
Speed of car (M) = 65 Unit/hour
Step-by-step explanation:
Given:
Speed equation;
455 = Mx
Time taken (x) = 7 hours
Find:
Speed of car (M)
Computation:
455 = Mx
455 = M(7)
Speed of car (M) = 65 Unit/hour
After a decimal point, you can always put 0's on the end and the value won't change.
So you just put two 0's at the end and get 6.600
Answer:
12. sometimes
13. always
14. always
Step-by-step explanation:
Exponential functions with a positive base are defined for all real numbers. Such functions will always have a positive value.

<h3>12)</h3>
The larger the base, the faster the decay for x < 0. In that part of the domain, 2^x > 10^x. (sometimes)
