8.49/4 = 2.1225
Sunblock 1 costs $2.12 per ounce of sunblock.
10.29/5 = 2.058
Sunblock 2 costs $2.06 per ounce of sunblock.
Sunblock 2 is the better buy because it is cheaper ounce-per-ounce.
Answer:
{(0,-5), (1, -3), (2, -1), (3, 1)
Step-by-step explanation:
If you plug in 1 for x you get f(x)=2(1)-5 which equals 2-5=-3
You would repeat these steps just going up by one number every time
The answer is 2:1.
The centroid separates the median, or the point from the midpoint of a side of a triangle with its opposite angle, at a ratio of 2:1, meaning that one segment is 1/3 the length of the median and the other segment is 2/3 the length of the median.
Answer:
504 m³
Step-by-step explanation:
There is only one statement that is true: B. The graph of the function is a parabola.
<h3>How to study and interpret the characteristics of quadratic equations</h3>
In this question we have a <em>quadratic</em> equation, whose characteristics have to be inferred and analyzed. We need to prove each of the five choices presented in the statement:
Choice A:
If we know that x = - 10, then we evaluated it at the function:
f(- 10) = (- 10)² - 5 · (- 10) + 12
f(- 10) = 162
False
Choice B:
By analytical geometry we know that all functions of the form y = a · x² + b · x + c always represent parabolae.
True
Choice C:
The <em>quadratic</em> function opens up as its <em>leading</em> coefficient is greater that 0.
False
Choice D:
If we know that x = 20, then we evaluate it at the function:
f(20) = 20² - 5 · (20) + 12
f(20) = 312
False
Choice E:
If we know that x = 0, then we evaluate it at the function:
f(0) = 0² - 5 · (0) + 12
f(0) = 12
There is only one statement that is true: B. The graph of the function is a parabola.
