Answer:
The correct answer is option C and D.
C). DC = 6√3
D). AC = 12√3
Step-by-step explanation:
Answer: In your problem, you said that they are squared. However, it is not written as squared. We just have to multiply them.
We can use the FOIL method.
(3b - 5c)(3x + 5y)
6bx + 15by - 10cx - 25cy
There are no like terms, so that expression is our final answer.
Z=22
180-120=60
2x+16=60
2x=44
Z=22
Answer:
Given: 
and 
.
Prove: 
Since , By the definition of perpendicular lines angles 1, 2, 3 and 4 are 90 degree. similarly , it means angles 5, 6, 7 and 8 are 90 degree.
We can say that,
, 
, 
and 
From figure it is noticed that the angle 1 and 5 are corresponding angles.
If two parallel lines are intersected by a transversal, then the corresponding angles are equal.
Since corresponding angles are congruent, therefore the line must be parallel to each other.
Hence proved that .
Answer:
1. 56.52 inches
2. 141,300 inches
Step-by-step explanation:
One turn of the tire is the circumference. Therefore, we have to find the circumference first. C = πd = 18π = 18 × 3.14 = 56.52 in
2500 rotations would be 2500 ⋅ 56.52 in = 141,300 in
