Suppose a city with population 100,000 has been growing at at rate of 6% per year. If this rate continues, find the pouplation in 17 years
Answer:
269277
Step-by-step explanation:
Suppose a city with population 100,000 has been growing at at rate of 6% per year. If this rate continues, find the pouplation in 17 years
We solve using the formula for exponential growth
Pt = P( 1 + r)^t
When
P = Initial population = 100000
Pt = Population after time t = x
r = Growth rate = 6%
t = Time in years = 17
Hence:
Pt = 100000( 1 + 0.06)¹⁷
Pt = 100000( 1.06)¹⁷
Pt = 269277.27858
Approximately the population in 17 years = 269,277

Another company charges $8 per month and $0.03 per minute used. Which equation below best respresents the total cost for the month, c, for m miuntes used?
Answer: c = 8 + 0.03m
Step-by-step explanation:
From the question, we are informed that a company charges $8 per month and $0.03 per minute used.
The equation that best respresents the total cost for the month, c, for m miuntes used will be:
c = 8 + (0.03 × m)
c = 8 + (0.03m)
c = 8 + 0.03m
For example if 10 minutes was used, the cost will be:
c = 8 + 0.03m
c = 8 + (0.03 × 10)
c = 8 + 0.3
c = $8.3

The mean marks of 100 students were calculated as 65. At the time of checking it was found the marks 40 and 50 was wrongly copied and weeded out Find the correct mean marks.
Answer:
[ Because those two numbers are removed you need to reduce the number of terms to 98. ]
☆Solution☆
N=100
Mean=65
(Wrong Numbers=40,50)
Now,
Mean=Sum/No. of items
or,65=Sum/100
▪Sum=65×100=6500
After removing the unnecessary numbers,
New Sum=6500-40-50=6410
New no.of terms(N)=100-2=98
Now,
New Mean=New Sum/New N
=6410/98
=65.41

Nina buys a small rug in the shape of a kite. The width of the rug is half its height. What are the width and area of the rug? (height 31 inches width 9 inches)
Answer:
[tex]Width = 20\ in[/tex]
[tex]Area = 400\ in^2[/tex]
Step-by-step explanation:
Given
See attachment for kite dimension
Required
Determine the width and the area
From the attachment, the height of the kite is:
[tex]Height = 31\ in + 9\ in[/tex]
[tex]Height = 40\ in[/tex]
The width which is half the height is:
[tex]Width = \frac{1}{2} * Height[/tex]
[tex]Width = \frac{1}{2} * 40\ in[/tex]
[tex]Width = 20\ in[/tex]
The area is:
[tex]Area = \frac{Height * Width}{2}[/tex]
[tex]Area = \frac{40\ in * 20\ in}{2}[/tex]
[tex]Area = 40\ in * 10\ in[/tex]
[tex]Area = 400\ in^2[/tex]

A map of Oklahoma uses a scale of 1.25 inches = 50 miles Ig Piedmont and Tulsa are 3.5 inches apart on the map how far is it to go from Piedmont to Tulsa AND Back
Answer:
280 miles
Step-by-step explanation:
It is given that :
Scale : 1.25 inches = 50 miles
In the map the distance between Piedmont and Tulsa is = 3.5 inches
So the actual distance between Piedmont and Tulsa in miles is given by :
1.25 inches = 50 miles
So, 3.5 inches = [tex]$\frac{50 \times 3.5}{1.25}$[/tex] miles
= 140 miles.
So when we go from Piedmont to Tulsa, it is 140 miles and we go back from Tulsa to Piedmont, it is another 140 miles.
Therefore, total distance = 140 + 140
= 280 miles

Answer:
x ≈ 7.1
Step-by-step explanation:
The circumference of this circle is 2πx.
65/360 of that circumference is said to be 8
so we can solve x from
65/360 · 2πx = 8
which can be simlified to
2πx = 8 · 360/65
πx = 288/13
x = 288 / (13π) ≈ 7.1
which answer choice is equivalent to the expression (x+2)^2 - 6x+2?
a. x^2 - 2x+8x
b. x^2 - 2x+6
c. x^2 - 6x+4
d. -5x^2 +6
Answer:
(x+2)^2 - 6x+2
(x+2)^2 = (x+2).(x+2)
= x(x+2) + 2(x+2)
= xx + x2 + 2x +4 ( x2 = 2x)
= x^2+ 4x +4
(x+2)^2 - 6x+2
x^2+ 4x +4- 6x+2
x^2+ 4x - 6x+2 +4
x^2- 2x+2 + 6 (b)

cos^2x + 2 cos x + 1 = 0 (4 points)
Answer:
cos^2x + (1+1)cos x + 1 = 0
or,cos^2x + cos x + cos x + 1 = 0
or,cos x(cos x + 1) + 1 (cos x + 1) = 0
or, (cosx + 1) + (cosx + 1) = 0
either
cosx + 1 =0 or cosx +1 =0
