Answer:
n=1+√47 or n=1−√47
Step-by-step explanation:
Let's solve your equation step-by-step.
n2−2n−48=−2
Step 1: Subtract -2 from both sides.
n2−2n−48−(−2)=−2−(−2)
n2−2n−46=0
For this equation: a=1, b=-2, c=-46
1n2+−2n+−46=0
Step 2: Use quadratic formula with a=1, b=-2, c=-46.
n=
−b±√b2−4ac
2a
n=
−(−2)±√(−2)2−4(1)(−46)
2(1)
n=

The population of a city in 2000 was 18,500 people. Since then the population has increased 4.8% every year. Determine the correct equation that would represent what the population would be in the year 2028.
Answer:
see below
Step-by-step explanation:
Consider the year 2000 to be year 0. This would make year 2028 year 8.
Population growth or decay function: [tex]A = Pe^{rt}[/tex]
where A is the final amount, P is the principal amount, r is the rate, and t is time.
[tex]A = 18,500e^{(0.048)(8)}[/tex]
This can be simplified to
[tex]A = 18,500e^{0.384}[/tex]

Can i get brainliest?
Hi there!
[tex]\large\boxed{x = 18}[/tex]
3x + 2x + 90 = 180
Begin by combining like terms:
5x + 90 = 180
Subtract 90 from both sides to isolate for x:
5x + 90 - 90 = 180 - 90
5x = 90
Divide both sides by 5 to further isolate:
5x/5 = 90/5
x = 18.

hat is the surface area of a cylinder that has a volume if 785.4in3 and a radius of 5 in?
A 471.2in2
B 10in2
C 150in2
D 4712.3in2
Answer:
A. 471.2 in²Step-by-step explanation:
Cylinder volume:
V = πr²hCylinder surface area:
A = 2πr(r + h)Find h from the first equation:
h = V/(πr²) = 785.4/(3.14*5²) = 10 inFind surface area:
A = 2π(5)(5 + 10) = 471.23 in²Correct choice is A
Answer:
volume of cylinder=πr²h
785.4=22/7×5²×h
h=785.4×7/(22×25)=9.99=10in
Step-by-step explanation:
surface area of cylinder =2πr(r+h)=2π×5(5+10)=
471.238898038in²
A 471.2in2 is your answer.

the cost of a ticket increases by 10% to £19.35 work out the original cost
Answer:
£17.59
Step-by-step explanation:
100 + 10 = 110% (Price of a ticket after increase)
110% = 19.35
1% = 19.35 ÷ 110 = 0.1759
100% = 0.1759 x 100 = 17.59
20, 18, 21, 18, 22, 24, 18, 23, 23, 24 Explain the meeting of the interquartile range as it relates to the number of students in the kindergarten classes
The interquartile range of the data-set is of 5.5, which means that the middle 50% kindergarten classes has a number of students that differ by at most 5.5.
What are the median and the quartiles of a data-set?The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.The first quartile(Q1) is the median of the first half of the data-set, and is also the 25th percentile.The third quartile(Q3) is the median of the second half of the data-set, and is also the 75th percentile.The interquartile range(IQR) represents the middle 50% of the distribution, and is given by Q3 - Q1.For this problem, the ordered data-set is given by:
18, 18, 18, 20, 21, 22, 23, 23, 24, 24.
There are 10 elements, hence:
The first half is 18, 18, 18, 20, which has median (18 + 18)/2, hence Q1 = 18.The second half is 23, 23, 24, 24, which has median (23 + 24)/2, hence Q3 = 23.5.Then the IQR is:
Q3 - Q1 = 23.5 - 18 = 5.5.
The IQR is of 5.5, which means that the middle 50% kindergarten classes has a number of students that differ by at most 5.5.

Answer and Step-by-step explanation:
You got the triangle at front, half of 6 is 3, so then you do 4 times 3 divided by 2, which is 6.
There are 4 of those triangles, so 4 times 6 is 24.
Now, we got two rectangles on top. 5 times 12 is 60, and 60 + 60 is 120.
the bottom rectangle is 6 times 12, which is 72.
Now we add.
24 + 120 + 72 is 216
