The scenario represents a linear function. The rate is at a constant increase therefore it is linear.
Linear because it’s a constant rate
Since it’s doubled, and doesn’t go at a constant rate, it is a exponential function
Exponential since it increases by a multiplicative rate. It’s not constant
Answer:
B, E
Step-by-step explanation:
2:9 is the simplified ver. of 4:18
8:36 is 2x 4:18
(NOT C: Included because the order does matter and this is a common mistake.)
Step-by-step explanation:
The given equation is
As a check for exactness we have
Hence the given equation is an exact differential equation and thus the solution is given by
thus the solution is given by
Similarly we have
Comparing both the solutions we infer
Hence the solution becomes
given boundary condition is that it passes through (1,1) hence
thus solution is
Answer:
(2, ∞)
Step-by-step explanation:
The function is not defined to the left of x=2 (assuming the independent variable is x). There is a vertical asymptote at x=2, so the function is not actually defined for x=2. However, the function is defined for all values of the independent variable greater than 2, so that is its domain.
(We don't actually know what the indpendent variable is, so we have expressed the domain in interval notation—avoiding the problem of naming the independent variable.)
Answer:
Step-by-step explanation:
ntroduction. Percent, p%
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100
80% = 80/100 = 80 ÷ 100 = 0.8
100% = 100/100 = 100 ÷ 100 = 1
Percentage of 80% of what number = 40?
80% of what number = 40 is equivalent to:
80% × ? = 40
80% × ? = 40
? =
40 ÷ 80% =
40 ÷ (80 ÷ 100) =
(100 × 40) ÷ 80 =
4,000 ÷ 80 =
50
