Remark
I didn't know this was a calculus question. How dumb of me.

The h's will disappear when the limit is taken.

answer - 1/6 which is A. If anyone else answers take their answer.

What is the fourth term in the binomial expansion (a+b)^6)
Dafna11 [192]

Answer:

20a^3b^3

Step-by-step explanation:

<u>Binomial Series</u>

(a+b)^n=a^n+\dfrac{n!}{1!(n-1)!}a^{n-1}b+\dfrac{n!}{2!(n-2)!}a^{n-2}b^2+...+\dfrac{n!}{r!(n-r)!}a^{n-r}b^r+...+b^n

<u>Factorial</u> is denoted by an exclamation mark "!" placed after the number. It means to multiply all whole numbers from the given number down to 1.

Example:  4! = 4 × 3 × 2 × 1

Therefore, the fourth term in the binomial expansion (a + b)⁶ is:

\implies \dfrac{n!}{3!(n-3)!}a^{n-3}b^3

\implies \dfrac{6!}{3!(6-3)!}a^{6-3}b^3

\implies \dfrac{6!}{3!3!}a^{3}b^3

\implies \left(\dfrac{6 \times 5 \times 4 \times \diagup\!\!\!\!3 \times \diagup\!\!\!\!2 \times \diagup\!\!\!\!1}{3 \times 2 \times 1 \times \diagup\!\!\!\!3 \times \diagup\!\!\!\!2 \times \diagup\!\!\!\!1}\right)a^{3}b^3

\implies \left(\dfrac{120}{6}\right)a^{3}b^3

\implies 20a^3b^3

Plz help and show work
scoundrel [369]

Answer:  If the 40% off coupon is used, the subtotal will be $12.69

The gratuity would be exactly $4.23   (He will probably leave $4.25)

Step-by-step explanation: To find out the amount  of the discount

.40 × 21.15 = 8.46

To find the new subtotal, subtract  12.15 - 8.46 = 12.69

To figure the tip:  .20 × 21.15 = 4.23

Changing the percent to a decimal means divide the 20 by 100.

The diameter of the circle above is 22 cm. What is the circumference of the circle? (Use = 3.14.)
postnew [5]

Answer:

69.08cm

The formula for the circumference is

pi times diameter=circumference

Since we are using 3.14 and we know the diameter we can plug that in

3.14 times 22= circumference

69.08=circumference
