27 students are going on a field trip4 students can ride in each carHow many cars will they need for the field trip?

Leviafan [203]

They need 7 cars for the field trip.

Step-by-step explanation:

The given is,

27 students are going to field trip

4 students in each car

Step:1

Let, T = Total students are going field trip

X = Students in each car

Y = Number of cars need for field trip

Step:2

From given,

T = 27

X = 4

Step:3

Numbers of cars need for field trip,

Y = $\frac{Total students are going field trip}{Students in each car}$

Y = $\frac{T}{X}$

= $\frac{27}{4}$

Y = 6.75 ( For the car, we need to convert the answer into whole number)

Y = 7 cars

Result:

They need 7 cars for the field trip, If 27 students are going on a field trip 4 students in each car.

Determine which values of p the following integrals converge. Give your answer in each case by selecting the appropriate inequal

sashaice [31]

Answer:

Step-by-step explanation:

$\int\limits^2_1 {\frac{1}{x(lnx)^p} } \, dx$

this can be done by substitute lnx = u

dx/x = du

When x =1, u =0 and when x =2, u = ln 2

So integral = $\int\limits^{ln2} _0 {du/u^p} \\\=\frac{u^{-p+1} }{-p+1}$

We find that this integral value is not definid for p =1

Hence for values of p other than 1, this converges.

When we substitute limits

$\frac{1}{1-p} ((ln2)^{1-p} -1)$

and converges for p ≠1

b) $\int\limits^1_0 {lnx}/x^p \, dx \\\int \frac{\ln \left(x\right)}{x^p}dx=\frac{1}{-p+1}x^{-p+1}\ln \left(x\right)-\frac{x^{-p+1}}{\left(-p+1\right)^2}+C$

So not converging for p =1

But ln x is defined only for x >0

So integral 0 to 1 makes this integral not valid and hence not convergent.
