If f(x) = 3x and g(x)=2x, what is (g o f)(x)?
5x
5x2
6x
6x2

Answers

Answer 1
Answer:

If you would like to solve (g ° f)(x), you can calculate this using the following steps:

(g ° f)(x) = g(f(x))

(g ° f)(x) = g(f(x)) = g(3x) = 2 * 3x = 6x

The correct result would be 6x.

Which terms and 45p4q have a GCF of 9p3? Check all that apply. 18p3r
27p4q
36p3q6
63p3
72p3q6

Answers

Answer:

 18p^3r

and  63p^3

Step-by-step explanation:

We have to check which term and 45p^4q has GCF  9p^3

GCF of  18p^3r   and  45p^4q= 9p^3

GCF of  27p^4q   and  45p^4q= 9p^4q

GCF of  36p^3q^6   and  45p^4q= 9p^3q

GCF of  63p^3   and  45p^4q= 9p^3

GCF of  72p^3q^6   and  45p^4q= 9p^3q

Hence, the correct answer is:

  18p^3r

and  63p^3
18p^3r and 63p^3 are the answer

Answers

Answer:

√(3) :1

Step-by-step explanation:

Given:

\vec{a}_{\vec{b}}=√(3)* \vec{b}_{\vec{a}}

|\vec{a}|cos\theta=√(3) *|\vec{b}|cos\theta

|\vec{a}|=√(3) *|\vec{b}|

|\vec{a}|:|\vec{b}|=√(3) : 1

If the rate 30 hot dogs per 5 minutes is reduced to a unit rate, the result is . Do not include units in your answer.

Answers

The notion of a unit rate is how much will happen in a unit of measurement. The question indicates there are 30 hotdogs in a total of 5 minutes, averaging 6 hotdogs per minute, or .1 hotdogs per second. This is done by dividing the total into equal 'chunks' of that unit of time.The question therefore does not make sense to "not include units".
I think it would be 6 hotdogs per 1 minute. Because that's a rate, and rates can be written as fractions,and fractions are division problems, so 30 divided by 5 is 6.
