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.
The total number of hamburgerssold were 17.
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.

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)
What is the function written in vertex form?
A.f(x) = 5(x + 4) – 80
B.f(x) = 5(x + 8) – 80
C.f(x) = 5(x + 4)2 – 80
D.f(x) = 5(x + 8)2 – 80
Use the formula for quadratic trinomial. Then you can form from a quadratic trinomial perfect square:
.
From the last given step you have that
.
Since 5·16=80, you can substitute the previous expression for perfect square into function expression and get:
.
This means, when x=-4, f(-4)=-80 and vertex has coordinates (-4,-80).
Answer: correct choice is C.

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
