Answer:
see below
Step-by-step explanation:
given: size of television is height = 37 in, length = 71 in.
A. using Pythagorean theorem:
parts given are legs which is the sides
looking for the hypotenuse.
B. formula:
a² + b² = c² or H² + L² = D²
where H = height = 37
L = length = 71
D = diagonal (which is req'd)
C. D² = 37² + 71²
D =
D =
D = 80 in (missing length)
D. size of television:
37 x 71 in
Diagonal is 80 in
hope it helps and good luck!
Answer:
a) The car will be worth $8000 after 2.9 years.
b) The car will be worth $6000 after 4.2 years.
c) The car will be worth $1000 after 12.7 years.
Step-by-step explanation:
The value of the car after t years is given by:
According to the model, when will the car be worth V(t)?
We have to find t for the given value of V(t). So
(a) $8000
V(t) = 8000
The car will be worth $8000 after 2.9 years.
(b) $6000
V(t) = 6000
The car will be worth $6000 after 4.2 years.
(c) $1000
V(t) = 1000
The car will be worth $1000 after 12.7 years.
