You must add 6 to complete the square.
x^2+12x+(6)=-5(6)
Answer:
1.5
Step-by-step explanation:
Answer: 4.2
Step-by-step explanation:
when you square root 18 you get 4.242. When rounded to the nearest tenth you get 4.2 since 4 is not nor is 5 and exceeds it.
Let
b---> the original amount of blue balls in the bag
p---> the original amount of pink balls in the bag
we know that
b=8+p
p=5
so
b=8+5----> b=13
step 1
Find the total of balls originally in the bag
total =13+5-----> 18
step 2
find <span>the probability that a person will pick a blue ball first
</span>Find P(b)
P (b)=13/18
step 3
Find the probability that a person will pick a pink ball second <span>without replacement
the total of balls now is (18-1)-------> 17
P(p)=5/17
step 4
Find </span><span>the probability that a person will pick a blue ball first and then a pink ball without replacement
</span>(13/18)*(5/17)-----> (13*5)/(18*17)------> 65/306-----> 0.21
the answer is
0.21
Step-by-step explanation:
we know that:
using this, we can see that x = 73 and y = 13
using this, tan(x-y) = tan(73-13) = tan(60)
therefore, A = 60
we know that tan(60) = √3
therefore, B = 3
