Answer:

\text{The area of kite is }190.44 m^2  

Step-by-step explanation:

Given the kite in which length of diagonals are given

we have to find the area of kite.

Length of diagonals are

p=9.2+9.2=18.4 m

q=6.9+13.8=20.7 m

\text{Area of kite=}\frac{pq}{2}

Area=\frac{18.4\times 20.7}{2}=\frac{380.88}{2}=190.44 m^2

\text{Hence, the area of kite is }190.44 m^2

d_1=9.2m+9.2m=18.4m\\d_2=6.9m+13.8m=20.7m\\\\Area\ of\ the\ kite:A=\frac{d_1\times d_2}{2}\\\\A=\frac{18.4\times20.7}{2}=9.2\times20.7=190.44\ (m^2)

A rectangle has a perimeter of 14centimeters and an area of 10 square cm. find its dimensions
WARRIOR [948]
Perimeter is all the way around and area is l x w

So 5 x 2 would be 10.....and 5 + 5 + 2 + 2 = 14

So the dimenstions are 5 x 2

What percent of a present amount of radioactive radium (226Ra) will remain after 1200 years? The half life of 226Ra is 1599 year
sp2606 [1]

Answer:

59.44%

Step-by-step explanation:

<em>M_{R} = \frac{M_{O} }{2^{n} }</em>

<em>n=\frac{t}{t\frac{1}{2} }</em>

<em>Where M_{R} = mass remaining</em>

<em>M_{O} =original mass.</em>

<em>t= time </em>

<em>t\frac{1}{2} =half life</em>

t\frac{1}{2} =1599,  t= 1200, M_{O} =226,  M_{R} =?

n=\frac{1200}{1599}

n= 0.750469

M_{R} = \frac{226}{2^{ 0.750469} }

M_{R} =134.3367amu

percentage of mass remaining = \frac{134.3367amu}{226amu} *100%

                                                   = 59.44%

(1) In 2015, the population of a small town was 8,000. The population is
borishaifa [10]

Answer:

Step-by-step explanation:

y= a*b x  (a is initial value  b = growth rate) y= 8000(-1)^1 x= 1.018^1 x 1.8

x = 0.1527 = time x 12.

f(x)=x. f ( x ) = x .  = 0.1527 x 12

or we can square so that x^2 = 1.8  and x = 1.34164 note this can only be used for the first 5 decimal place.

This shows the exponential growth we expand and introduce y = 8000(-1)^12 to find one year.

One year y-1^12 this represents 144 the 1.8% of the y = 144 the starting point of 1/12 on axis.

f(x)=2x. f ( x ) = 2x add y (1)^1 would show year 2 at the same rate,
