If length AM = AK then it is isosceles.

M(-1,-6), A(-4,5)

AM=((5-(-6))²+(-4-(-1)))^(1/2)=11.401

A(-4,5) and K(5,-2)

AK=((-2-5)²+(5+4)²)^(1/2)=11.401

so the triangle is isosceles.

steposvetlana [31]

Answer:

$307.5.

Step-by-step explanation:

We have been given that Elena's aunt bought her a $150 savings bond when she was born.When Elena is 20 years old, the bond will have earned 105% in interest.

To find bond's value after 20 years we will add 105% of 150 to 150.

$\text{Bond's value after 20 years}=150+(\frac{105}{100}\times 150)$

$\text{Bond's value after 20 years}=150+(1.05\times 150)$

$\text{Bond's value after 20 years}=150+157.5$

$\text{Bond's value after 20 years}=307.5$

Therefore, the bond will be worth $307.5, when Elena will be 20 years old.
