A car is traveling at a speed of 44 feet per second. what is the car's speed in miles per hour? how many miles will the car trav
Sladkaya [172]
44 feet. 3600 seconds. 1 mile
----------- ---------------------- -----------
1 second 1 hour. 5280 feet

I wrote it this way so the units cancel out. You are multiplying the fractions by each other

The car is going 30 mph, and will go 120 miles in 4 hours.

I do not understand what number I am supposed to use for “y=4x+__. I thought it would be 6 because that’s how many hexagons are
skad [1K]
Based on the table, it should be 2.
Y=4x+2 works for all x and y values in the table.

Which of the following statements regarding the expansion of (x + y)^n are correct?
kompoz [17]

Answer:

A, B and D are true statements.

Step-by-step explanation:

We are given a binomial expansion

(x+y)^n=^nC_0x^ny^0+^nC_1x^{n-1}y^1+^nC_2x^{n-2}y^2+...........+^nC_nx^0y^n

(x+y)^n=x^n+nx^{n-1}y+^nC_2x^{n-2}y^2+...........nxy^{n-1}+y^n

Now we will check each option

Option A: The coefficients of x^n and y^n both equal 1.

If we see first and last term of the expansion, This statement is true.

Option B: For any term x^ay^b in the expansion, a + b = n.

Let we take 3rd term of expansion ^nC_2x^{n-2}y^2

Here, a=n-2 and b=2

If we do  a+b = n-2+2=n

a+b=n is true statement.

Option C: For any term x^ay^b in the expansion, a - b = n.

Let we take 3rd term of expansion ^nC_2x^{n-2}y^2

Here, a=n-2 and b=2

If we do  a-b = n-2-2=n-4≠n

a-b=n is false statement.

Option D: The coefficients of x^ay^b and x^by^a are equal.

If we take second term from beginning and last of the expansion.

\text{Coefficient From beginning } nx^{n-1}y=n

\text{From last } nxy^{n-1}=n

This statement true.
