Answer:

A. Q(2, -1), S(-6,5)

Step-by-step explanation:

Reflection rule across the x-axis:

(x, y) → (x, -y)
P(2, 1) → Q(2, -1)
R(-6, -5) → S(-6, 5)

Correct choice is A

Solve each equation. Write null if the equation has no solution. Write all if all numbers solve the equation. Write fractions in

Mademuasel [1]

1) 33+a=12a
33 = 11a
33/11 = a
a = 3

2) -6n+2=4n-5
2 = 10n-5
7=10n
n = 7/10
n = 0,7

3) 2.4b-7=b+15.4
2.4b=b+22.4
1.4b=22.4
b = 22.4/1.4
b = 16

What are the coefficients for the binomial expansion of (a + b)^3?

sashaice [31]

Answer:

Required coefficient :coefficient of 1st, 2nd, 3rd and 4th term are 1, 3,3,1 respectively.

Explanation:

Formula for binomial expansion is $(a+b)^n=^nC_0\cdot a^n\cdot b^0+^nC_1\cdota^(n-1)\cdot b^1+------b^n$

We will substitute the values a=a, b=b and n=3 in the formula for binomial expansion we will get

$^3C_0\cdot a^3\cdot b^0+^3C_1\cdot a^2\cdot b^1+^3C_2\cdot a^1\cdot b^2+^3C_3\cdot a^0\cdot b^3$

After simplification of the terms we will get

$a^3+3\cdot a^2\cdot b+3\cdot a\cdot b^2+b^3$

Since, $^nC_r=\frac{n!}{(r!)(n-r)!}$

Therefore the required coefficient : coefficients of 1st, 2nd, 3rd and 4th term are 1, 3,3,1 respectively.

anyanavicka [17]

We know that

The angular velocity is 10π rad/sec
step 1
convert to rad/min
1 min-----60 sec
X min----> 1 sec
X=1/60 min
V=10π rad/(1/60)------> V=600 π rad/min

the answer is the option
D)The angular velocity is 600π rad/min.
