Answer: see graph below
<u>Step-by-step explanation:</u>
The equation of a circle is: (x - h)² + (y - k)² = r² where
- (h, k) is the center
- r is the radius
(x - 4)² + (y - 2)² = 9
- (h, k) = (4, 2)
- r² = 9 ⇒ r = 3
To graph the circle, mark an x at the center (4, 2). Then plot a point 3 units (the radius) to the right of the center, another point 3 units up from the center, a third point 3 units to the left of the center, and a fourth point 3 units down from the center. "Connect the dots" to form a circle.
Answer:Answer: the total number of views that the video got over the course of the first 27 days is 718833
Step-by-step explanation:
The number of views that the video got each day increased by 18% per day. It means that the number of views is increasing in geometric progression. The formula for determining the sum of n terms(days), Sn of a geometric sequence is expressed as
Sn = (ar^n - 1)/(r - 1)
Where
n represents the number of terms(days) in the sequence.
a represents the first term in the sequence.
r represents the common ratio.
From the information given,
a = 1500
r = 1 + 18/100 = 1.18
n = 27 days
Therefore, the sum of the first 27 terms, S27 is
S27 = (1500 × 1.18^(27) - 1)/1.18 - 1
S27 = (1500 × 86.26)/0.18
S27 = 718833
Hopefully It helps:)
Answer:
x-6
Step-by-step explanation:
The mistake when expanding the bracket 3(x-6),3 was supposed to multiply 6 but instead it was added to 6 instead
the correct working
3(x-6)+(4x+12)-6x
3x-18+4x+12-6x
(3x+4x-6x)+(-18+12)
=x-6
Answer:
36
Step-by-step explanation:
I just have a feeling
Move all terms that don't contain
y to the right side and solve.
Your answer would be
Y= 10+2x
