Matchsticks are used to make a sequence of
patterns:
3 , 5 , 7 ...
Find the nth term rule for the number of
matchsticks in pattern n
Answer:
Tn = 1 + 2n
Step-by-step explanation:
Given the arithmetic sequence
3 , 5 , 7 ...
The nth term of an AP is expressed as;
Tn = a + (n-1)d
a is the first term = 3
d is the common difference = 5-3 = 7-5 = 2
n is the number of terms
Substitute
Tn = 3 + (n-1)(2)
Tn = 3 + 2n-2
Tn = 1 + 2n
Hence the nth term rule for the number of matchsticks in pattern n is 1 + 2n
Below is the table of values of a function. Write the output when the input is n.
Answer:
when input = n, Output = 4n
Step-by-step explanation:
Output = k(input)
Where,
k = constant
Find k When output = 8 and input = 2
Output = k(input)
8 = k(2)
8 = 2k
k = 8/2
k = 4
Find k When output = 28 and input = 7
Output = k(input)
28 = k(7)
28 = 7k
k =28/7
k = 4
Find output when input = n
Output = k(input)
= 4(n)
= 4n
Output = 4n
when input = n, Output = 4n

The four small circles are identical. The total area of the small circles is 36π square inches. What is the area of the larger circle?
Answer:
Check pdf
Step-by-step explanation:
The radius of the larger circle is 12 inches. Then the area of the larger circle will be 144π square inches.
What is the area of the circle?Let r be the radius of the circle. Then the area of the circle will be
A = πr² square units
The four small circles are identical. The total area of the small circles is 36π square inches. Then the radius of each small circle is given as,
36π = 4 × (πr²)
r² = 9
r = 3 inches
Then the radius of the larger circle is calculated as,
R = 4r
R = 4 × 3
R = 12
Then the area of the larger circle will be given as,
A = π × (12)²
A = 144π square inches
The radius of the larger circle is 12 inches. Then the area of the larger circle will be 144π square inches.

A survey of 7th grade students found that 18 out of 32 students prefer to buy their lunch at school instead of bring it from home. What percent of students is that? Write your final answer as a percentage.
Answer: 56.25%
Step-by-step explanation: You would divide 18 over 32, which would get the decimal 0.5625. Then you would multiply this by 100/100 which would get 56.25/100. This would get you 56.25%.
(b) A farmer uses of his land to plant
cassava, of the remaining land to plant
maize and the rest vegetables. If
vegetables cover an area of 10 arces, what
is the total area of the farmer's land.
Answer:
Cassava = ⅓ or 33.333%
Maize = ⅔x⅔ = 44.444%
total so far =77.777%
Remaining vegetable area =(100–77.777%) = 22.222%
If remaining area vegetables = 22.222% = 10 acres
Maize = ⅔x⅔ = 44.444% or 20 acres
Cassava = ⅓ or 33.333% or 15 acres
Total land area = 45 acres.

April, x, slept 9 hours; Evelyn slept 2/3
less than that.
Evelyn slept _______________ hours. Write the equation as both a decimal and fraction.
live to be 80 years old and sleep 8 hours a day, How many years have I slept
Solution
A day has 24 hours
24 = 8 + 8 + 8
So you spent 1/3 of your time sleeping.
You can get the same answer if you do 8/24
8/24 = (8 ÷ 8) / ( 24 ÷ 8) = 1/3
All you need to do now is to find 1/3 of 80
1/3 of 80 = 1/3 × 80 = 80/3
80 / 3 = (78 + 2) / 3 = 78 / 3 + 2 / 3 = 26 + 2/3
So that is 26 years + ( 2/3 of a year)
What is 2 / 3 of a year?
Since 2 /3 of a year is a fraction of a year, the answer for 2 / 3 of a year will be in months.
1 year = 12 months.
Just find out what 2/3 of 12 is
2/3 of 12 is 2/3 times 12
2/3 times 12 = (2 times 12) / 3 = 24 / 3 = 8 months
Putting everything together, you slept for 26 years and 8 months during your lifetime.

The value of the computer decreased exponentially throughout the five-year period.
What was the average annual of decrease (in dollars per year) over the two-year interval from t=2 to r=4?
table:
_Time___/_Value__

Therefοre , the sοlutiοn οf the given prοblem οf functiοn cοmes οut tο be the average yearly rate οf decrease (in dοllars per year) is $100.
Explain functiοn.

A service is made up οf many unique parts that wοrk tοgether tο prοduce unique οutcοmes fοr each input.
Here,
[tex]= > V(t) = V(0) * e^{(-kt)[/tex]
By using the numbers at times t=1 and t=3, we can determine the decay cοnstant k:
[tex]= > V(1) = 400 = V(0) * e^{(-k1)[/tex]
[tex]= > V(3) = 100 = V(0) * e^{(-k3)[/tex]
[tex]= > 100/400 = e^{(-k3) / e^{(-k1)[/tex]
[tex]= > 1/4 = e^{(-2k)[/tex]
[tex]= > ln(1/4) = -2k[/tex]
[tex]= > k = ln(4)/2[/tex]
[tex]= > k ≈ 0.69315[/tex]
The value οf the cοmputer at times t=2 and t=4 can nοw be determined using the algοrithm fοr V(t):
[tex]= > V(2) = V(0) * e^{(-k2)[/tex]
[tex]= > V(4) = V(0) * e^{(-k4)[/tex]
[tex]= > V(4)/V(2) = e^{(-k4) / e^{(-k2)[/tex]
[tex]= > V(4)/V(2) = e^{(-2k)[/tex]
[tex]= > V(4)/V(2) = e^{(-0.69315*2)[/tex]
[tex]= > V(4)/V(2) =0.5[/tex]
Over this time periοd, the average yearly rate οf decline (in dοllars per year) is:
Ratiο οf decline equals value shift. (time interval)
=> V(2) - V(4) = (rate οf decline) / (4 - 2)
=> (amοunt οf reductiοn) is equal tο (V(2) * (1 - 0.5)) / 2.
=> (amοunt οf decline) is equal tο (V(2) * 0.5) / 2.
=> V(2) / 4 equals (rate οf decline)
=> (rate οf reductiοn) equals 400 / 4
=> rate οf decline) = $100 annually
As a result, οver the twο-year periοd frοm t=2 tο r=4, the average yearly rate οf decrease (in dοllars per year) is $100.

Quadrilateral abcd is rotated 90 degrees clockwise about the origin. What are the coordinates of A'B'C'D?
Answer:
your answer is A
Step-by-step explanation:
have a nice day!! ^_^
The coordinate of A` is (5,5) , the coordinate of B` is (5,1), the coordinate of C` is (2,1) and the coordinate D` is (1,5).
What is the coordinate of a point?A pair of number that describes the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinate of a point. Coordinates are usually denoted by (x, y).
From the figure we can see that A` is 5 unites right of vertical line and 5 unit upward the horizontal line. So, the coordinate of A` is (5,5).
Similarly, B` is 5 unit right of vertical line and 1 unit upward the horizontal line. So, the coordinate of B` is (5,1).
C` is 2 unit right of vertical line and 1 unit upward the horizontal line. So, the coordinate of C` is (2,1).
And, D` is 1 unit right of vertical line and 5 unit upward of horizontal line. So, the coordinate of D` is (1,5).
Hence the coordinates of A`B`C`D` is (5,5), (5,1), (2,1) and (1,5) respectively.
