The correct answer is B.
-5*3^0=-5
-5*3^3=-135
-5*3^7=-10935
5 oz for 1.49.....1.49/5 = 0.298 per oz
12 oz for 3.59...3.59/12 = 0.299 per oz
when rounded, the unit rates are equal
The answer:
the vertex formula is V( -b/2a, f((-b/2a) )
so if The graph of y=ax^2+bx+c is a parabola that opens up and has a vertex at (0,5), then -b/2a = 0, implies b = 0, and when b =0 f((-b/2a = 0/2a=0))=f(0)
in our case, f(x)=<span>ax^2+bx+c, and it implies f(0) = c </span>≠ 5
so there is no value of a, b and c which verifies the equation of vertex, the set solution is {∅} (the empty set)
The variable being tested in an experiment is the (b) response variable
<h3>How to determine the variable name?</h3>
The statement is given as:
<em>what is the variable being tested in an experiment?</em>
As a general rule, the variable being tested in an experiment is referred to as the dependent variable
The dependent variable is represented with y and it is also known as the response variable
Hence, the variable being tested in an experiment is the (b) response variable

Answer:
B) 9 square units
Step-by-step explanation:
Split the shape into a right triangle and a rectangle.
The rectangle is 2 by 3, so multiply 2 x 3 for the area: 6.
The triangle has a height of 3 and a base of 2. Multiply to get 6. Then divide by 2 to get: 3.
Add 6 + 3 to get 9 square units.
Hope it helps!
