Answer:
(8) d. 4/3 (9) a. (X - 4)^2 + (y-4)^2= 25
Step-by-step explanation:
8. CENTER OF CIRCLE: O (2,6)
radius of circle : r = √4 = 2
if m = 4/3 line: y = 4/3 x
perpendicular distance (d) from center of circle to line y = 4/3 x is
d = |((4/3 x 2) + (-1) x 6)| / √((4/3)² + (-1)²) = |(-10/3)| / √(25/9) = (10/3) / (5/3) = 2
d = r means line touch with circle
9. center of circle is the intersection of the diagonals of rectangle (4,4) and its radius is 5 (illustrated)
the equation of circle: (X - 4)^2 + (y-4)^2= 25
Answer:
The best answer is C
Step-by-step explanation:
A is not correct because the total amount of people that participated is 300
B is no correct because the 75% would be more than 20
C is correct because 20% of 100 is 20
D is wrong because A has more people supporting raising it.
correct me if I am wrong.
Okie
First find D
In this case it is log x
Now find those terms which are log x, log 2x, log 3x, ….. log 8x
Now add them
You will get log x36 :)
Answer:
72
Step-by-step explanation:
If the rates d and c are flowers per day, we have ...
150/d = 120/c
d -c = 18
__
Multiplying the first equation by cd/30, we have ...
5c = 4d
Multiplying the second equation by 4 gives ...
4d -4c = 72
Adding these equations together, we get ...
5c +4d -4c = 4d +72
Simplifying and subtracting 4d leaves ...
c = 72
Charlie can plant 72 flowers per day.
This exercise is about creating two-dimensional shapes. The resulting shape is a quadrilateral - Square. See the attached for the lines drawn.
What was noticed about the two lines drawn?
- The two lines are drawn each had parallel pairs; and
- They were perpendicular to one another.
<h3>What is the meaning of perpendicularity?</h3>
When two lines intersect with one another such that they create a right angle, perpendicularity has occurred and both lines are said to be perpendicular to one another.
Hence:
- AB ⊥ BC
- BC ⊥ CD
- CD ⊥ DA; and
- DA ⊥ AB.
