zmey [24]

Answer:

Use the Pythagorean theorem for right triangles to solve this

a^2 + b^2 = c^2 where 'a' and 'b' are the legs of the triangle and 'c' is the hypotenuse

so:

8^2 + b^2 = 17^2 solve for the second leg, b

64 + b^2 = 289

b^2 = 289 - 64= 225

b = 15

Fittoniya [83]

Answer:

Mr. Chang will have 15714.90 dollars.

Step-by-step explanation:

p = 650

r = $7.8/4/100=0.0195$

Number of periods or n = $5\times4=20$

Future value formula is : $p[\frac{(1+r)^{n}-1}{r} ]$

Putting the values in formula we get;

$650[\frac{(1+0.0195)^{20}-1}{0.0195} ]$

= $15714.90

Hence, Mr. Chang will have 15714.90 dollars.
