Answer:
b = 24 ft
h = 10 ft
Step-by-step explanation:
120 = ½hb
120 = ½h(3h - 6)
240 = h(3h - 6)
240 = 3h² - 6h
80 = h² - 2h
0 = h² - 2h - 80
0 = (h - 10)(h + 8)
h = 10 ft or -8 ft
we ignore -8 as it makes no sense for a triangle side length.
b = 3(10) - 6 = 24 ft
The perimeter of the triangle is 13.56 units.
The perimeter of a shape on a coordinate plane is found by finding the distance between all points, and then adding them together. It's easier to write it out than to type so I'll attach a photo of my work.
Answer:
it a
Step-by-step explanation:
Answer:
14.6328% , $5836.03
Step-by-step explanation:
Here we are going to use the formula

= 39000
r=?
= 11000
n=8
Hence








Hence r= 0.1463
In percentage form r = 14.63%
Now let us see calculate the value of car in 2003 that is after 12 years
we use the main formula again

= 39000
r=0.1463
= ?
n=12




Hence the car's value will be depreciated to $5840.34 (approx) by 2003.
