Suppose a, b, and c are all negative numbers. How do you find the distance between the points (a,b) and (a,c)?

Alex787 [66]

Answer:

Step-by-step explanation:

Let's say if b = -2 and c = -3

-2-(-3) = 1 that would be the distance between them. If it was D then you would need absolute value.

Hope this helps! Have a nice day!

The population of a certain species of insect is given by a differentiable function P , where P(t) is the number of insects in t

Dmitriy789 [7]

Answer:

Option C, dP/dt=1/5P

Step-by-step explanation:

The change is population of insects is directly proportional to the rate of change of population

Hence,

$\frac{dP}{dt} \alpha P$

Or $\frac{dP}{dt} = kP$

where K is the proportional constant

We will find the value of k

Keeping the given values of rate of change of population and population in above equation, we get -

$\frac{2}{10} = k\\k = \frac{1}{5}$

Hence,

$\frac{dP}{dt} = \frac{1}{5} P$

Prove that for every two positive integers a and b that

Aleks [24]

$$(a+b)(\frac{1}{a}+\frac{1}{b}) \ \textgreater \ or = 4$
\\
1+a/b+b/a + 1 \geq 4
$ $$(a+b)(\frac{1}{a}+\frac{1}{b}) \ \textgreater \ or = 4$
$

distributed

choose 1 as your lowest positive integer

plug 1 into a and b

1 + 1 + 1 + 1 $\geq 4$

The equation ac=5 represent a(n) ___ variation

TEA [102]

Answer:

Direct Variation

Step-by-step explanation:

The relationship between two variables such that y = kx if k is a nonzero number. Also, as one quantity increases, the second quantity increases or as one quantity decreases, the second quantity decreases. Therefore ac=5 is a direct variation
