Which quadratic function has a leading coefficient of 2 and a constant term of –3?f(x) = 2x^3 – 3

f(x) = –3x^2 – 3x + 2

f(x) = –3x^3 + 2

f(x) = 2x^2 + 3x – 3

Answers

Answer 1

Answer: quadatic means 2nd degree, means highest exponent of placeholder is 2
leading coefient is the number that is in front of the highest power x
constant term is the one that doesn't have an x witht it

quadratic
2nd and last fn are quadratic

leading coefient of 2 is first and last fn

constant term is -3 for first and last fn

answer is last function

Find the 4th term of (x+2)^10

Answers

(x + 2)¹⁰

Would take the terms in reducing powers of x, and increasing powers of 2.

1st term = ¹⁰C₀ x¹⁰(2)⁰ = x¹⁰

Second term = ¹⁰C₁ x¹⁰⁻¹(2)¹ = ¹⁰C₁ x⁹(2)¹

Third term =    ¹⁰C₂ x¹⁰⁻²(2)² = ¹⁰C₂ x⁸(2)²

Fourth term = ¹⁰C₃ x¹⁰⁻³(2)³ = ¹⁰C₃ x⁷(2)³

So we shall now simplify the fourth term which is = ¹⁰C₃ x⁷(2)³

ⁿCr = n! /( r!(n -r)! )

¹⁰C₃ = 10! /( 3!(10 -3)! ) = 10! / (3!*7!) = (10 *9 * 8* 7!) / (3!*7!)

= 10*9*8 / 3! = (10*9*8) / (3*2*1) = 120

4th term = ¹⁰C₃ x⁷(2)³ = 120 *x⁷*(2)³ = 120*2³*x⁷

   = 120*8x⁷

   = 960x⁷

So the fourth term in reducing powers of x = 960x⁷

Give a description of a 3/4- turn of the minute hand on a clock face.

Answers

Answer: This turn will make a change of 45 minutes.

Step-by-step explanation: Now, a full turn of the minute hand in a clock face is an hour or 60 minutes.

Now, if we only do a 3/4 of a turn, the number of minutes passed is equal to:

3/4*60min = 45min

So in a 3/4 turn of the minute hand, the "change" in the time will be one of 45 minutes.

If the minute hand has turned 3/4 of the way around the face, it is equal to 45 minutes. (45/60)

Which term describes a fraction that has a variable or variable expression in its numerator, its denominator, or both?A. Variable fraction
B. Rational expression
C. Rational fraction
D. Variable expression

Answers

The right answers is B. Rational expression.

This is true given that the statement establishes a term that describes a fraction that has a variable or variable expressionin its numerator, denominator or both, that is, this is the concept of the quotient of two polynomials called rational expression. Finally, we can get the following rational expressions that matches with this concept, namely:

$(1) \ (1)/(x) \n \n (2) \ (2x-1)/(x+1) \n \n (3) \ (x^(2)-1)/(x^(2)+1)$
