A shopkeeper sold 12 bags on the first day. The number became four times
every subsequent day. Find the total number of bags sold in seven days.
48
84
65,532
65,535
The total number of the bags sold by the shopkeeper will be 65532.
What is number series?The sequence formed by using the numbers is termed as the number series.So in this question from day one to day seven each day the sold items are multiplied by 4.
So the mathematical expression will be given as:
[tex]=(12\times 4^0)+(12\times 4^1)+(12\times 4^2)+(12\times 4^3)+(12\times 4^4)+(12\times 4^5)+(12\times 4^6)[/tex]
[tex]=12+48+192+768+3072+12288+49152\\\\=65532[/tex]

A table has a length of 9 and a width of 4. What is the perimeter?
Answer:
26
Step-by-step explanation:
Assume the table is a rectangle.
A rectangle has 2 sides with the length of the length and 2 sides with the length of the width.
perimeter = sum of the lengths of the sides
perimeter = 9 + 9 + 4 + 4
perimeter = 26
Answer:
26
Step-by-step explanation:
Assuming the table is rectangular...
Rectangles = 4 sides
2 sides = 9
Other 2 sides = 4
Perimeter = adding up the sides

Step-by-step explanation:
the length of the side sqaure A is 50% OF THE LENGTH OF THE SIDE SQUARE b
Let's say the side length of square A is x, which means the side length of square B is 2x.
Then, the area of square A can be written as , and the area of square B can be written as .
There's no diagram here with shaded region, so I'll just find the area of square A as a percentage of the area of square B:

How do we find coterminal angles for
degrees? Radians?
Answer:
To find coterminal angles, add or subtract 360 degrees of the terminal angle as many times possible.
To find radians, use this formula:
Degrees × π/180°
Coterminal angles point in the same exact direction.
In degree mode, you can add on 360 degrees to get a coterminal angle.
Example: 90 degrees is coterminal to 450 degrees because 90+360 = 450. Both angles 90 and 450 point directly north.
You can also subtract 360 from the angle to get a coterminal counterpart.
Example: Given the angle 700, it is coterminal to 340 since 700-360 = 340
This process of adding or subtracting 360 can be done as many times as you like.
------------------------------
For radian mode, you'll add or subtract 2pi radians to get a coterminal angle. This is because 2pi radians = 360 degrees by definition.
Examples:
pi is coterminal to 3pi because pi+2pi = 3pi, both point directly westpi/4 is coterminal to 9pi/4 because pi/4 + 2pi = pi/4 + 8pi/4 = 9pi/421pi/4 is coterminal to 13pi/4 because 21pi/4 - 2pi = 21pi/4 - 8pi/4 = 13pi/4Find the amount you would pay for a jacket that costs $52 that is advertised at 25% off.

What amount of money must you invest at 6.8% compounded monthly, in order to have $10,000 after 10 years? Round your answer to the nearest dollar.
The amount of money which is invested at 6.8% compounded monthly, in order to have $10,000 after 10 year is $5076.
What is compound interest?
Compound interest is the amount charged on the principal amount and the accumulated interest with a fixed rate of interest for a time period.
The formula for the final amount with the compound interest formula can be given as,
[tex]A=P\times\left(1+\dfrac{r}{n\times100}\right)^{nt}\\[/tex]
Here, A is the final amount (principal plus interest amount) on the principal amount P of with the rate r of in the time period of t.
The rate of interest is 6.8% on the amount which is compounded monthly
The value of final amount is $10,000 after the time period of 10 years. There are total 12 months a year. Thus, the value of principal amount using the above formula is,
[tex]10000=P\times\left(1+\dfrac{6.8}{12\times100}\right)^{12\times10}\\10000=P\times1.97\\P=\dfrac{10000}{1.97}\\P=5076.14\\P\approx5076[/tex]

Step-by-step explanation:
From the graph/image that you have provided said translated shift of
f(x) -> g(x)
f(x) = x^2 , g(x) = a(x -h)^2 +k
h is shift right/left
k is shift up/down.
It appears that the shift is left 2 and up 1.
h = -2 and k = 1
g(x) = (x - (-2))^2 +1
g(x) = (x + 2)^2 + 1
