Answer:

The formula to determine the length of rectangle with perimeter and width is L = $\frac{P - 2W}{2}$

Step-by-step explanation:

Given as :

The perimeter of rectangle = P

The length of rectangle = L

The width of rectangle = W

∵ Perimeter of rectangle given as P = 2 × Length + 2 × Width

I.e P = 2 L + 2 W

Or, 2 L = P - 2 W

∴ L = $\frac{P - 2W}{2}$

Hence The formula to determine the length of rectangle with perimeter and width is L = $\frac{P - 2W}{2}$ Answer

Answer:

5842 people after 2 months

Step-by-step explanation:

Given

Initial Value: $a =10000$

Rate: $r = 20\%$ every 6 months

Required

Number of people using it after 2 months

The function follows an exponential model.

So, we need to first write out the function.

If Rate: $r = 20\%$ every 6 months

Then

Rate: $r = 40\%$ after 1 year

$r = 0.04$

The function is represented as:

$y = ar^x$

So:

$y = 10000 * 0.04^t$

For 2 months, we have:

$t = 2\ months$

Convert to years

$t = \frac{2}{12}$

$t = 0.167$

$y = 10000 * 0.04^t$

$y = 10000 * 0.04^{0.167}$

$y = 5842$

Let x represent the measurment of an acute angle in degrees. the ratio of the complement of x to the supplement of x is 2: 5. gu

Nadusha1986 [10]

Ratio of complement of x : supplement of x
2 : 5
⇒ 2 times the supplement of x will be equal to 5 times the complement of x

5(90 - x) = 2 (180 - x)
450 - 5x = 360 - 2x
5x - 2x = 450 - 360
3x = 90
x = 30°

Complement of x = 90 - x = 90 - 30 = 60
Supplement of x = 180 - x = 180 - 30 = 150
Ratio:
60 : 150
60 ÷ 30 : 150 ÷ 30
2 : 5 (checked)
