Joe is telling the truth because why would he lie about how many students were there?

Answer:

No.

Explanation:

I don't agree with Joe because if he is counting 40 students, then he has to count himself as well which will make 41 students.  

Hopefully, This helped out. :)

A racecar is traveling at a constant speed of 120 miles per hour. How many feet does it travel in 6 seconds? Remember that 1 mil
snow_tiger [21]

Answer:

1056 ft

Step-by-step explanation:

We need to convert the units from miles per hour to feet per second:

recall that i mile = 5280 ft, and one hour is 3600 seconds, so we do the conversion of the 120 miles per hour speed as follows:

120 \,\frac{mi}{h} = 120\,\frac{5280\,\,ft}{3600\,\,s} = \,176\,\,\frac{ft}{s}

which means that the car cover 176 ft in one second. Therefore, in 6 seconds it will cover 6 times this:

distance = 176 * 6 = 1056 ft

Find the 7th term of the expansion of (3c + 2d)9.
SIZIF [17.4K]
\bf (3c+2d)^9\\\\&#10;-------------------------------\\\\&#10;&#10;\begin{array}{crcll}&#10;term&&value\\&#10;-----&&-----\\&#10;1&&(3c)^9(2d)^0\\&#10;2&+9&9(3c)^8(2d)^1\\&#10;3&+36&(3c)^7(2d)^2\\&#10;4&+84&(3c)^6(2d)^3\\&#10;5&+126&(3c)^5(2d)^4\\&#10;6&+126&(3c)^4(2d)^5\\&#10;7&+84&(3c)^3(2d)^6\\&#10;\end{array}

now.. if you notice, the exponent for the 1st term, is dropping on each term subsequently, start with highest, 9 in this case, and drops drops drops, till on the last term, will be 0

the exponent for the second term, starts off at 0, and goes up up and up on each term

that part is simple... now, the coefficient for them

the first one will have a coefficient of 1, so we can take a closer look at the 2nd instead

the coefficient for the second is 1* 9/ 1
(1) the coefficient of the current term, (9) the exponent of the 1st term, and (1) the exponent of the 2nd term on the next term

for example, how did we get 84 for the 4th term?   (36 * 7) / 3 = 84

and so on for all subsequent terms
