Is the length of DE is shown, what other length can you determine for this diagram? Help me please
Stels [109]

Answer:

Another length of this diagram FE=12.

Step-by-step explanation:

According to diagram

In triangle FED, EM is perpendicular bisector of FD.

In ΔFED, EM ⊥ FD and FM=MD

In ΔFME and ΔDME

FM=DM                       (Given)

∠FME=∠DME             (each 90°)

ME=ME                       (Common)

ΔFME ≅ ΔDME  (By SAS congruence property)

Therefore, FE≅DE  (by CPCT)

But DE=12

So, FE=12

Thus, Another length of this diagram FE=12.

Hayden invested $750 for 3 years at an interest rate of 0.035 how much interest did he earn in that time
4vir4ik [10]

Answer:

78.75 (simple)    81.54 (compound)

Step-by-step explanation:

Simple interest without compounding : I = P * (1 + rt) -P  

I: interest         P: primary investment       r: annual rate   t: time in year

I = =750 * (1+ 0.035*3) -750 =  78.75

Compound interest      I = (P *(1 +r)^ t)-P

I' = 750*(1+0.035)*(1+0.035)*(1+0.035) - 750 = 81.54
