Which part do you need help on?
F-1(x) = x\5 + 6/5
hope this helps
Answer:
C. 0.6625 square inches
Step-by-step explanation:
To get the area of the net of a square pyramid;
We need to find the are of the square base and the area of the four triangles;
Area of the square base = s²
= (0.25 in)²
= 0.0625 in²
Area of one triangle = 0.5 × b × h
= 0.5 × 0.25 in × 1.2 in
= 0.15 in²
Area of the four triangles = 0.15 in² × 4
= 0.6 in²
Therefore;
Area of the net square pyramid = 0.0625 in² + 0.6 in²
= 0.6625 square inches
Step-by-step explanation:
Part A:
car 1 => exponential function
car 2=> linear function
Part B:
car 1 => the function f(x) = 45,000 • (0.9)^x
car 2= > the function f(x) = 45,000 - (3,000)x
Part C:
after 13 years, the value of :
car 1 => 45,000 • (0.9)^13 = $ 11,438.40
car 2=> 45,000 - (3,000)(13) = $ 6,000
the difference is = 11,438.40 - 6,000
= $ 5,438.40
its better to Belinda to purchase car 1.
Multiply what she owed by 4
