Which statement is true? All constants are of degree 0. All monomials are of degree 1. All binomials are of degree 1. All trinomials are of degree 3.

Answers

Answer 1
Answer: Among the statements only the First statement is true, All constants are of degree 0. Because monomials can have any degrees while binomials will always be in the 1 degree. Also, trinomials will always have a degree of 2.
Answer 2
Answer:

Answer:

Option 1 is correct.

Step-by-step explanation:

Given the following statements we have to choose the true statement.

First option: All constants are of degree 0

The constant term of a polynomial is the term in which the variable does not appear i.e no variable include in that term i.e of degree 0.

Second option: All monomials are of degree 1

Monomials are the polynomials containing 1 term not necessarily of degree 1. Hence, the above statement not true.

Third option: All binomials are of degree 1

Binomials are the polynomials containing 2 term not necessarily of degree 1. Hence, the above statement not true.

Fourth option: All trinomials are of degree 3

Trinomials are the polynomials containing 3 terms not necessarily of degree 3. Hence, the above statement not true.

Hence, option 1 is correct.

What is equation modelling? What is a mathematical equation and expression?

  • Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
  • A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.
  • A mathematical equation is used to equate two expressions.

Given is that on Sunday, a local hamburger shop sold a combined total of 428 hamburgers and cheeseburgers. The number of cheese burgers sold was three times the number of hamburgers sold.

Assume that the number of hamburgers sold are [x]. Then, the number of cheese burgers sold will be [3x]. Then, we can write -

x + 3x = 428

4x = 428

x = 17

Therefore, the total number of hamburgerssold were 17.

The equation you can use is x + 3x = 428 with x as the number of cheeseburgers and 3x the number of hamburgers 
you solve for x and get 4x= 428 and x=107

so 321 hamburgers were sold that day.

C.f(x) = 5(x + 4)2 – 80
D.f(x) = 5(x + 8)2 – 80

Answers

The right answer for the question that is being asked and shown above is that: "C.f(x) = 5(x + 4)2 – 80." Write the function in standard form. f(x) = 5x2 + 40x. Factor a out of the first two terms. f(x) = 5(x2 + 8x). Form a perfect square trinomial. = 16. f(x) = 5(x2 + 8x + 16) – 5(16). The vertex form is C.f(x) = 5(x + 4)2 – 80

Use the formula (a+b)^2=a^2+2ab+b^2 for quadratic trinomial. Then you can form from a quadratic trinomial perfect square:

x^2 + 8x + 16=x^2+2\cdot x\cdot 4+4^2=(x+4)^2.

From the last given step you have that

f(x) = 5(x^2 + 8x + 16)-5\cdot 16.

Since 5·16=80, you can substitute the previous expression for perfect square into function expression and get:

f(x)=5(x+4)^2-80.

This means, when x=-4, f(-4)=-80 and vertex has coordinates (-4,-80).

Answer: correct choice is C.

Answers

Answer:

5.8%

Step-by-step explanation:

H= 1/r (in P - in A)

H=24

P=2000

A=5000

24= 1/r (in2000 - in5000)

24r = in 2000 - in 5000

r = in 2000 - in 5000
