B. 1+2√x3

C. 3x3−x2+12

D. x4−16

Answers

Answer 1
Answer:

The cubic binomial expression with a positive leading coefficient is 1+2x^3

How to determine the cubic binomial expression?

A cubic binomial expression has the following properties:

  • It has 2 terms
  • One of its variable term has a power of 3

This means that a cubic binomial expression is represented as:

ax^3 + b or b + ax^3

From the question, we understand that it has a positive leading coefficient.

This means that:

a > 0

From the list of options, we have:

1+2x^3

Hence, the cubic binomial expression with a positive leading coefficient is 1+2x^3

The graph of a linear equation may not be a straight line.

Answers

If this is a true false question. The answer is false. The idea behind a linear equation is that it is a straight line. Proof for this is the y=mx+b equation. Where m defines a constant slope(or in other words, a straight line) and b represents how high the line appears.
As you can see there is nothing that could bend the line into a more curvy shape (things that do bend are polynomials and such)

The integral diverges.

Answers

Answer:

The integral diverges

Step-by-step explanation:

∫₁³ 2 / (x − 2)^(8/3) dx

∫₁³ 2 (x − 2)^(-8/3) dx

There is a discontinuity in the function at x = 2.  Splitting this into two integrals:

∫₁² 2 (x − 2)^(-8/3) dx + ∫₂³ 2 (x − 2)^(-8/3) dx

(-6/5) (x − 2)^(-5/3) |₁² + (-6/5) (x − 2)^(-5/3) |₂³

your school sells tickets for its winter concert. Student tickets are $5 and adult tickets are $10. If your school sells 85 tickets and makes $600, how many of each ticket did they sell?

Answers

Let s be the number of student tickets and a be the number of adult tickets.
s + a = 85; a = 85 - s
Also,
5s + 10a = 600

Substituting a from the first equation
5s + 10(85 - s) = 600
-5s = -250
s = 50
a = 85 - 50 = 35
The school sold 50 student tickets and 35 adult tickets.
