Answer:
The cost of parts was $65.
Step-by-step explanation:
Let the cost of parts = x
35 + 21(3) + 1.10x = 169.50
98 + 1.10x = 169.50
71.50 = 1.10x
71.50/1.10 = 65
For 2x^2 + 3x = -1 => 2x^2 + 3x + 1 = 0 => a = 2, b = 3, c = 1
b^2 - 4ac = 3^2 - (4 x 2 x 1) = 9 - 8 = 1
Answer:
Step-by-step explanation:
Find the expression to represent how much you would expect a cub to weigh 
days after it's born as exponential growth function 
where 
is the initial panda's weight and 
is the rate of growth.
A newborn red panda weighs 100 grams, then 
A healthy cub gains about 7% of its newborn weight per day, then
Hence,
