<u>4x²y²</u> <em>- 2y⁴</em> - 8xy³ + 9x³y <em>+ 6y⁴ </em>- 2xy³ - 3x⁴ <u>+ x²y²</u>
= <u>5x²y²</u> <em>+4y⁴</em> - 10xy³ + 9x³y - 3x⁴ <em>combined like terms</em>
= -3x⁴ + 9x³y + 5x²y² - 10xy³ + 4y⁴ <em>descending exponent order based on "x"</em>
If Julian wrote his list in descending order based on "y", then the order would be reversed.
Answer: 4y⁴
<em>Note: I am assuming we have to determine the angle 'Ф'.</em>
Answer:
The value of Ф = 22.6°
Step-by-step explanation:
Given
hypotenuse = 13
To determine:
Angle = Ф = ?
Using the trigonometric ratio
cos Ф = adjacent / hypotenuse
here
so substituting adjacent = 12, hypotenuse = 13 in the equation
cos Ф = adjacent / hypotenuse
cos Ф = 12 / 13
Ф = arccos (12/13)
Ф = 22.6°
Therefore, the value of Ф = 22.6°
Can’t help DDDD: bcoz link is a scam
The formula for volume of a cylinder is V=π r^2 h.
So plug in,
320π=<span>π r^2 20
solve (sadmep (opposite of pemdas))
divide pi out
320=r^2 20
divide 20 out
16=r^2
square root of 16 is 4, so the radius is 4.
Since the 2r=d, the diameter is 8.
P.s. lol it thought I was copying an answer from online...
