We know that
Applying the Pythagoras Theorem
c²=a²+b²
in a square
a=b
c is the diagonal-----> 84 m
c²=2a²--------> a²=c²/2-----> a²=84²/2-----> a²=3528-----------> a=√3528 m

the answer part a) is
√3528 m or 59.40 m

the area of the pen is a²------> 3528 m²

the answer Part b) is
3528 m²

Answer:

$f(a) = \frac{(a+5)}{(a-1)}$

Step-by-step explanation:

Given : $f(x) = \frac{(3+x)}{(x-3)}$

In order to find $f(a+2)$ we will substitute $(a+2)$ for $x$ in the given function, that is :

$f(a) = \frac{(3+a+2)}{(a+2-3)}$

$f(a) = \frac{(a+5)}{(a-1)}$

Julie invested 3000 in a simple interest account for 2 years. At the end of the 2 years, she had earned $75 in interest. What wa

Dahasolnce [82]

The simple interest rate was: 1.25%

Step-by-step explanation:

Simple interest is given by:

$A = Prt\\Here\\A => Interest\\P=>Principal\ Amount\\r => Rate\\t => Time\ in\ years$

Given

Principal amount =$3000

Time = t = 2 years

Interest amount = A = $75

putting the values in the formula

$75 = 3000 * r * 2\\75 = 6000r$

Dividing both sides by 6000

$\frac{6000r}{6000} = \frac{75}{6000}\\r = 0.0125\\$

So,

The rate is:

0.0125 * 100 = 1.25%

Hence,

the simple interest rate was: 1.25%
