Answer:

Summary. If the equation ends with a false statement (ex: 0=3) then you know that there's no solution. If the equation ends with a true statement (ex: 2=2) then you know that there's infinitely many solutions or all real numbers

Step-by-step explanation:

The velocity v of the flow of blood at a distance r from the central axis of an artery of radius R is given below, where k is th
andrew11 [14]
The average rate of blood flow is given by

\displaystyle\frac1{R-0}\int_0^Rv(r)\,\mathrm dr=\frac kR\int_0^R(R^2-r^2)\,\mathrm dr
=\dfrac kR\left(R^2r-\dfrac13r^3\right)\bigg|_{r=0}^{r=R}
=\dfrac kR\left(R^3-\dfrac13R^3\right)
=\dfrac{2kR^2}3

Question 2 Two trains leave the station at the same time, one heading west and the other east. The westbound train travels at 95
lianna [129]

Answer:

it will take 1.4 hours for the two trains to be 294 miles apart

Step-by-step explanation:

Let t be the time taken for each train

The westbound train travels at 95 miles per hour.

Speed of westbound train = 95

time = t

Distance = speed * time = 95 t

The eastbound train travels at 115 miles per hour

Speed of eastbound train = 115

time = t

Distance = speed * time = 115 t

both trains are 294 miles apart means the distance between both trains are 294 miles

So we add the distance of both trains and set it equal to 294

95t + 115t = 294

210 t =294

t = 1.4

So, it will take 1.4 hours for the two trains to be 294 miles apart

Which point corresponds to the real zero of the graph of y=log3(x+2)-1?
insens350 [35]

The point that corresponds to the real zero of the graph of y=log3(x+2)-1 is (1, 0)

<h3>Logarithm function</h3>

Given the logarithmic function expressed as:

y=log3(x+2)-1

The point that  corresponds to the real zero of the graph is at the point where y = 0

log3(x+2)-1 = 0

log3(x+2) = 1

log3(x+2) = log3 3
x + 2  = 3

x = 3 - 2

x = 1

Hene the point that corresponds to the real zero of the graph of y=log3(x+2)-1 is (1, 0)
