Answer:
Step-by-step explanation:
1.

c+9=±8
either c=8-9=-1
c=-8-9=-17
so c=-1,-17
D
2.
8x^2-3=2
8x^2=5


so A
3.

so D
or
answer:
61.712
Step-by-step explanation:
60 feet = 18.288
left wire = 80-18.288 = 61.712
Answer:
Let E denote the event of choosing a jury with 10 men and 2 women.
The sample space for selecting 12 members from the pool contains 55C12 elements.
The number of ways of selecting 10 men and 2 women is 26C10 29C2.
The probability of event E =
The probability of selecting a jury with 10 men and 2 women is 0.005 (0.5%).

Answer:
RS = √(b² +(c -a)²)
Step-by-step explanation:
Put the given point coordinates in the given formula:
- R = (x₁, y₁) = (0, a)
- S = (x₂, y₂) = (b, c)
RS = √((b -0)² +(c -a)²)
RS = √(b² +(c -a)²)
Answer: Correct
Step-by-step explanation:
The conclusion is valid. Since
and
, we know that ABCD is a parallelogram because it has two pairs of parallel sides. Also, since
, we know that ABCD is a parallelogram with a pair of consecutive congruent sides, making it a rhombus.
