Answer:
Solution given:
<u>A.coordinate are</u>
A(-2,3)
B(0,-3)
C(4,5)
<u>B</u><u>.</u><u>Each</u><u> </u><u>length</u><u> </u><u>are</u><u> </u><u>:</u>
we have
length
now
AB:=
units
BC:=
units
AC:=
units
<u>C.</u><u> the </u><u>figure</u><u>:</u>
<u>By</u><u> </u><u>using</u><u> </u><u>Pythagoras</u><u> </u><u>law</u>
base[b]=AB=perpendicular [p]=AC
hypotenuse [h]=BC
we have
h²=p²+b²
substituting value
()²=2p²
16*5=2*()²
80=2*4*10
80=80
<u>SO</u><u> </u><u>IT</u><u> </u><u>IS</u><u> </u><u>RIGHT</u><u> </u><u>ANGLED</u><u> </u><u>ISOSCELES</u><u> </u><u>TRIANGLE</u><u>.</u>
Jason's insurance pays 80% of the cost after he pays a $200 deductible. The deductible is Jason's responsibility. The insurance does not pay this and calculates the 80% AFTER it is subtracted from the total cost.
That's 1200 - 200 = 1000.
The insurance pays 80% of 1000. Percent means "out of 100" (per means "for every" and "cent" means 100 --> think CENTury...100 years). So 80% means 80 out of 100. That is,
. To find 80% of 1000 we multiply: 
If decimals are more your thing then represent 80% as .80 and multiply (1000)(.80) = 800.
Now, that's what the insurance pays. So out of that $1,000 the insurance pays $800 leaving Jason with a bill of $200 plus the deductible (another $200). That means Jason pays $400.
