5x + 10y = 18
x = y -6, we substitute this into first equation.
5x + 10y = 18
5*(y - 6) + 10y = 18
5y - 30 + 10y = 18
So it the last option from the top.
Surface area of a prism=2(long x wide)+2(long x high )+2(wide x high)
Data:
long=5 m
wide=2 m
high=2 m
Surface area of this prism=2(5 m * 2 m)+2(5 m*2 m)+2(2 m*2m)
=2(10 m ²)+2(10 m²)+2(4 m²)
=20 m²+20 m²+8 m²
=48 m²
Answer: C 48 m²
A. (x+8)^ 2 + 1
B. (x-3)^ 2 - 8
C. ( x - 3/2) ^ 2 - 1/4
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:)
