SOLUTION
From the sequence give
–3, 1, 5, 9, . . .
The first term, a = -3
The common difference, d = 4 (gotten by adding 4 to the next term).
The number of terms required n = 6.
Formula for sum of an arithmetic sequence is given by
Substituting these values into the equation above we have
Hence, the answer is 42, option B
Answer:
12 in
Step-by-step explanation:
sin(28°)=
a=sin(28°)*25
=11.7367
≈12
Answer:
See answer below
Step-by-step explanation:
x² - 10x + 30 = 0
x² - 10x = -30
x² - 10x + 25 = -30 +25 1/2 of the x term and square that number and add to
both side.
x² -10x + 25 = -5
(x - 5)(x - 5) = -5
=
If you are in Algebra II , then the answer is not a real answer it will be
(x - 5)² = ±5i
Answer:
29
Step-by-step explanation:
There would be 29 highways connecting 2 cities
Answer:
4/9
Step-by-step explanation:
If you add the ratios, it gives you the total, so 4 + 5 = 9. 9 total students. Since boys is represented by 4, then 4/9 is the fraction for boys and 5/9 is the fraction for girls.
