Kilo means 1000 so 1 kiometer=1000 meter
so every 1000 meter=1 kilometer
to convert,, just divide meters by 1000 and get km
2950/1000=2.95km

Find the distance between parallel lines whose equations are y = x - 6 and y = x + 8.

Sidana [21]

Answer:

Step-by-step explanation:

Distance between y2 = x + 8 and y1 = x - 6

y2 - y1 = (x + 8) - (x - 6) = 14

A store has 7 red shirts, 15 black shirts, 13

AleksAgata [21]

Answer:First you have to add all of the shirts together, which gives you: 40

Since 15 of those are black, then you need to put those 15 over the total number of 40, making it 15/40.

Then you must simplify by the highest number that will go into both, and since that number is 5, it will then go into 15 three times and it will go into 40 eight times.

That leaves you with the answer of: 3/8

Assuming that the equations define x and y implicitly as differentiable functions x=f(t),y=g(t) find the slope of the curve x=f(

Mumz [18]

The given equations are
$x(t+1)-4t \sqrt{x} =9$ (1)
$2y+4y^{3/2}=t^{3}+t$ (2)

When t=0, obtain
$x=9 \\ 2y+4y^{3/2}=0 \,\,=\ \textgreater \ \, y(1+2 \sqrt{y} )=0 \,=\ \textgreater \ \,y=0$

Obtain derivatives of (1) and find x'(0).
x' (t+1) + x - 4√x - 4t*[(1/2)*1/√x = 0
x' (t+1) + x - 4√x -27/√x = 0
When t=0, obtain
x'(0) + x(0) - 4√x(0) = 0
x'(0) + 9 - 4*3 = 0
x'(0) = 3
Here, x' means $\frac{dx}{dt}$ .

Obtain the derivative of (2) and find y'(0).
2y' + 4*(3/2)*(√y)*(y') = 3t² + 1
When t=0, obtain
2y'(0) +6√y(0) * y'(0) = 1
2y'(0) = 1
y'(0) = 1/2.
Here, y' means $\frac{dy}{dt}$ .

Because $\frac{dy}{dx} = \frac{dy}{dt} / \frac{dx}{dt}$ , obtain
$\frac{dy}{dx} |_{t=0}\, = \frac{1/2}{3}= \frac{1}{6}$

Answer:
The slope of the curve at t=0 is 1/6.

Which statement is modeled by the expression?

Afina-wow [57]

A librarian has 150 books to be placed on shelves with an equal number of books on each shelf. If k is the number of shelves to be used, then 150/k is the number of books on each shelf.

Example : lets say there are 10 shelves.....so k = 10
150/10 = 15 books on each shelf.

There is a population of 15,500 bacteria in a colony. If the number of bacteria doubles every 234 hours, what will

saveliy_v [14]

Answer:

2,48,000

Step-by-step explanation:

Initial population of bacteria = 15,500

Bacteria doubles after every 234 hours

So, after 0 (zero) hours, no of bacteria = 15,500

After 234 hours, no. of bacteria = 2(15,500) = 31,000

After 468 hours, no. of bacteria = 2(31,000) = 62,000 (2*234 = 468)

After 702 hours, no. of bacteria = 2(62,000) = 124,000 (3*234 = 702)

After 936 hours, no. of bacteria = 2(124000) = 2,48,000 (4*234 = 936)
