To find the solution set we must factor the quadratic equation first.
7
- 28
= 7( [tex] q^{2} [/tex - 4)
= 7(x + 2)(x - 2) = 0
x = {-2, 2}
This means that if x equals -2, or 2 the whole expression would equal zero. Hope this helps!
Find the common ratio r for the geometric sequence, and use r to find the next 3 terms n 1, 2, 3, 4, 5, 6, 7 f(n) 1,4,16,64
mote1985 [20]
Divide the given terms:
4/1 = 4
16/4 = 4
64/16 = 4
R = 4
The next term is the previous term multiplied by 4.
64 x 4 = 256
256 x 4 = 1024
1024 x 4 = 4096
The next three terms are: 256, 1024, 4096
Answer:
a = sqrt(b^2 + c^2 - 2bc cosA) = sqrt(13^2 + 6^2 - 2 * 13 * 6 * cos 50) = sqrt(169 + 36 - 156 cos 50) ≈ sqrt(205 - 100.3) ≈ sqrt(104.7) ≈ 10.2
a ≈ 10.2
c / sin C = a / sin A
sin C = c sin A / a = 6 sin 50 / 10.2 ≈ 0.4491
C = arcsin(0.4491) ≈ 26.7
C ≈ 26.7°
B = 180 - A - C ≈ 180 - 50 - 26.7 ≈ 103.3
B ≈ 103.3°
Step-by-step explanation:
There is no relationship between the grade level and the number of siblings each student has.
Explanation:
All the points are scattered
The answer would be X= 19, Y=33, R=24
