Answer:
No real solutions.
Step-by-step explanation:
x² + 6x + 10 = 0
a = 1
b = 6
c = 10
D = b² - 4ac = 6² - 4*1*10 = 36 - 40 = - 4
- 4 < 0,
so this equation has no real solutions.
Answer:
Mean: 6
Median: 6
Range: 8
Step-by-step explanation:
Mean is found by adding up all the values in the set and dividing by the amount of numbers in the set (in this one there are 8) 2+3+4+5+7+8+9+10=48. 48 divided by 8 = 6.
Median is the number in the middle, when the numbers in the set are ordered from least to greatest. Since there are two middle numbers in this set we add them together and divide by 2. 5+7=12. 12 divided by 2 = 6.
Range is found by taking the largest number and subtracting the smallest number from it. 10-2=8.
Answer: arc length = r * θ = (3 in) * (135°) = (3 in) * (3π / 4 rad) = 9π / 4 in.
Step-by-step explanation:
1. 102°
2. 56°
3. 104°
4. 138°
5. 95°
6. 133°
Answer:
Rational, irrational, rational, irrational
Step-by-step explanation:
-115.5: all negative numbers are rational
23.083: 3 is recurring- recurring numbers are irrational
2 under root 9 = 6
the number goes on without a pattern= irrational
