Answer:
25
Step-by-step explanation:
a2+b2=c2
3^2+4^2=c^2
9+16=25
25^2=625
Sqrt of 625 = 25
Answer:
1
Step-by-step explanation:
note (g - f )(a) = g(a) - f(a)
g(a) - f(a)
= 2a + 4 - (a - 4)
= 2a + 4 - a + 4
= a + 8
Thus
(g - f)(- 7) = - 7 + 8 = 1
Answer:
the second one
Step-by-step explanation:
because g(x) and f(x) is bout the same
Answer:
a) The arithmetic sequence with common difference 2 that has 8 as the first term.
b) The arithmetic sequence of common difference -5 and first term 15.
Step-by-step explanation:
Let's use for example the arithmetic sequence with common difference 2 that has 8 as the first term. Then the first two terms of this sequence are:
8, and (8+2) = 10 Therefore the second term is 10.
Another arithmetic sequence of common difference -5 and first term 15. The firs two terms of this sequence are:
15, and (15 - 5) = 10. Therefore again a 10 as second term.
