Answer:
AC and BD are vertically oposite
and both sides are equal (equilateral) so AC = BD
As i think
Answer:15b^2-5b^3+24b-16
Step-by-step explanation:
(4-b)(5b^2+5b-4)
Open the brackets
20b^2+20b-16-5b^3-5b^2+4b
Collect like terms
20b^2-5b^2-5b^3+20b+4b-16
15b^2-5b^3+24b-16
4w+5+33=90
4w=90-5-33
4w=52
w=13
Answer:
P(A and B) = 0.1 = 10%
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is

In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question, we have that:

What is P(A and B)?


P(A and B) = 0.1 = 10%
Answer:
The rate of change: 1/5
Initial value: (0,-1)
Step-by-step explanation:
The rate of change is easily 5/25, we just have to simplify it to 1/5.
To get the intial value, just subtract (2,9) by the rate of change twice.
