In 10 seconds Lauren counts 5 vehicles passing by her house at that rate how many vehicles would passing by in one hour

Dafna11 [192]

Answer:

1,800 vehicles

Step-by-step explanation:

We need to find what fraction of an hour 10 seconds is, so we will divide 60 (minutes) by 1/6 (minutes). From solving this, we will get 360. That is how many 10 second chunks pass in an hour. We will multiply 360 by 5, and we get 1,800 vehicles!

Simplify thise expression 6ab + (–3x) + 2ab

Thepotemich [5.8K]

Simplify the following:

6 a b - 3 x + 2 a b

Grouping like terms, 6 a b - 3 x + 2 a b = -3 x + (6 a b + 2 a b):

-3 x + (6 a b + 2 a b)

a b 6 + a b 2 = 8 a b:

Answer: -3 x + 8 a b

How do i do 3 part a ?

WINSTONCH [101]

In general the binomial expansion is

$(a+b)^n = {n \choose 0} a^0 b^n + {n \choose 1} a^1 b^{n-1} + {n \choose 2} a^2 b^{n-2} + ... + {n \choose n} a^n b^0$

So in our case, because we want ascending powers of x we'll write,

$(-3x + 1)^{11} = {11 \choose 0} (-3x)^0 1^{11} + {11 \choose 1} (-3x)^{1} 1^{10} + {11 \choose 2} (-3x)^{2} 1^9 + {11 \choose 3 } (-3x)^3 1^8 + ...$

We need to calculate the binomial coefficients:

${11 \choose 0} = 1$

${11 \choose 1} = 11$

${11 \choose 2} = \dfrac{11 \times 10}{2} = 55$

${11 \choose 3} = \dfrac{11 \times 10 \times 9}{3 \times 2} = 165$

$(-3x+1)^{11} = 1 (-3x)^0 1^{11} + 11(-3x)^{1} 1^{10} + 55 (-3x)^2 1^{9} + 165 (-3x)^3 1^8 + ...$

$(1-3x)^{11} = 1 -33 x + 495 3x^2 - 4455 x^3+ ...$
