What similarity property, if any, can be used to show that the following two triangles are similar ?
Natalka [10]

Answer:

A) SSS

Step-by-step explanation:

We have,

\frac{AC}{DF}=\frac{10}{15}=\frac{2}{3}\\\frac{AB}{DE}=\frac{12}{18}=\frac{2}{3}\\\frac{BC}{EF}=\frac{8}{12}=\frac{2}{3}\\\text{Thus,}\\\frac{AC}{DF}=\frac{AB}{DE}=\frac{BC}{EF}\\

Since the sides are in proportion, the two triangles are similar by the SSS test.

Sebastian invested $7,100 in an account paying an interest rate of 8 1 4 \% compounded monthly. Eva invested $7,100 in an accoun
Alexxx [7]

Answer:

Given:

Sebastian :

Principal(invested)= $7,100

Rate of interest=  8.14% compounded monthly

Eva:

Principal(invested)= $7,100

Rate of interest= 8.12% compounded continuously

Step-by-step explanation:

After 5 years,

In Sebastian case:

Amount= Principal*(1+R/100)^{t}

Amount = 7100*(1+8.14/100)^{12*5}

Amount= 7100*1.0814^{60}

Amount=7100*109.4415

Amount= $777,034.43

In Eva case,

Amount= Principal*e^{Rt/100}

Amount = 7100*e^{0.0812*12*5\\}

Amount= 7100*130.5818

Amount= $927,130.92

Difference between their money=$927,130.92-777034.43

                                                 =$150,096.49

Eva has $150,096 more money than Sebastian.
