Answer:

$6y^3+17y^2+22y+15$

Step-by-step explanation:

This is the product of a binomial (two terms) in the variable y with a trinomial (three terms) in the variable y as well. Arrange the terms of each expression as noted in the attached image, and complete the boxes with the products of each vertical header with each horizontal header in the appropriate cell of the table. Then combine all like terms (marked in orange and green) to get the final answer:

$6y^3+17y^2+22y+15$

4 of 7 June rolls a fair dice 234 times. How many times would June expect to roll a one?

alexandr402 [8]

Answer: 39 times

Step-by-step explanation: A fair dice has 6 sides with each side having a different number between 1 and 6. Therefore, the probability of rolling a 1 is 1/6. To find out how many times June would expect to roll a 1 after rolling the dice 234 times, you must multiply 234 by 1/6 to get the answer of 39.

siniylev [52]

Answer:

Step-by-step explanation:

1. Isolate Y by subtracting 6x from both sides.

2. Divide everything by 5, since 5 is the coefficient of Y

Final equation:

Y = $-\frac{6}{5} x -3$

Hope this helps!

Prove the identity. cosx sin (x+y) - sinx cos(x+y) = siny

Jet001 [13]

Answer:

In the explanation

Step-by-step explanation:

Going to start with the sum identities

sin(x+y)=sin(x)cos(y)+sin(y)cos(x)

cos(x+y)=cos(x)cos(y)-sin(x)sin(y)

sin(x)cos(x+y)=sin(x)cos(x)cos(y)-sin(x)sin(x)sin(y)

cos(x)sin(x+y)=cos(x)sin(x)cos(y)+cos(x)sin(y)cos(x)

Now we are going to take the line there and subtract the line before it from it.

I do also notice that column 1 have cos(y)cos(x)sin(x) in common while column 2 has sin(y) in common.

cos(x)sin(x+y)-sin(x)cos(x+y)

=0+sin(y)[cos^2(x)+sin^2(x)]

=sin(y)(1)

=sin(y)
