Answer:
28
Step-by-step explanation:
7 x 4 = 28
:)
An approximate number, that can be calculated mentally, is by using the rule of 72: Divide 72 by the interest in % to give the number of years needed to double the money.
In this case, the approximate number of years
n= 72/4=18 years (approximately)
Precise value by compound interest formula:
2P=P*(1.04)^n
=>
1.04^n=2
take logs on both sides
nlog(1.04)=log(2)
n=log(2)/log(1.04)=17.673 years
Answer with explanation:
Given: △ABC is an isosceles triangle with legs AB and AC.Also, △A Y X is also an isosceles triangle with legs A Y and AX.
To Prove: △ABC ~ △A Y X
Proof with Statement
1. △ABC is isosceles with legs AB and AC; △A Y X is also isosceles with legs A Y and AX.
2.AB ≅ AC and A Y ≅ AX.→definition of isosceles triangle
3.AB = AC and A Y = AX →→ definition of Congruency.
4.→→A Y × AC=AX × AC⇒[Multiplication property of equality]
5.≡A Y × AC=AX × AB⇒[Substitution property of equality]

----------------[Division property of equality]
7.Also, ∠A is common angle between two triangles.That is,
∠A=∠A------------[Reflexive property]
⇒Missing statement and Reason in the entire proof.
8.△ABC ~ △AYX----[SAS]
