Marcus states that the polynomial expression 3x3 – 4x2y + y2 + 2 is in standard form. Ariel states that it should be y2 – 4x2y +
lora16 [44]

Answer:

Here Ariel is wrong because 3x^3 is higher power than y^2

3x^3 goes first

then the mixed term -4x^2y

then the y^2

then the 2

So, Marcus is right

Standard form means that you write the terms by descending degree. here's main rules how to write polynomial expression in the standard form:

1. write the term with the highest exponent first (terms of third degree in our case 3x^3 );

2. write the terms with lower exponents in descending order (term -4x^2y followed by y^2 );

3. remember that a variable with no exponent has an understood exponent of 1 (here are no such terms);

4. a constant term (a number with no variable) always goes last (term 2).

Answer:

H = V0y t - 1/2 g t^2     equation for vertical height of object with initial speed     (V0y = V0 sin theta)

If H is to be considered an absolute value from t = 0

h = H + 3 = V0y t - 1/2 g t^2  + 3  where h is height from ground

Given the geometric sequence where a_1 = 3 and r = √2 find a_9
sesenic [268]
To find n-therm of a geometric sequence, we are going to use the formula a_{n} =a _{1} r^{n-1}
where:
a_{n} is the term we are looking for
a _{1} is the first term 
r is the ratio 
n is the position of the number in the sequence 

From the question we now that a _{1} =3, r= \sqrt{2}, and n=9. Lets replace those values into our formula to get:
a _{9} =3( \sqrt{2} )^{9-1}
a_{9} =3 \sqrt{2} ^{8}
a_{9} =48

We can conclude that in our geometric sequence a_{9} =48; therefore, the answer is A.
