Answer:

$48 {m}^{5} {n}^{6}$

Step-by-step explanation:

$6{m}^{3} {n}^{3} \times 8 {m}^{2} {n}^{3}$

$8 \times 6 = 48$

$6{m}^{3} {n}^{3} \times 8 {m}^{2} {n}^{3} = 48 {m}^{3 + 2} {n}^{3 + 3}$

Therefore

$48 {m}^{5} {n}^{6}$

If angle x=55% and angle y=35, calculate the following 1.cos(x+y)

Setler79 [48]

Answer:

cos(X+Y) = cos(55+35) = cos(90) = 0

Step-by-step explanation:

cos(X+Y) = cosXcosY - sinXsinY

cos(55+35) = cos(55)cos(35) - sin(55)sin(35)

cos(55+35) = cos(55)cos(35) - cos(90-55)cos(90-35)

cos(55+35) = cos(55)cos(35) - cos(35)cos(55)

cos(55+35) = 0

cos(90) = 0

A standard die is rolled 600 times. How many times would you expect to roll a number

jekas [21]

Their are 3 numbers less than 4 on a die with 6 sides so 3 is 50% of 6 so then it should land on a number less than 4 50% of the 600 rolls to get 300
