Answer:
173%
Step-by-step explanation:
So, if one big square represents one whole it means each small square represents 1% as there are 100 of them in each large square.
The first square is completely shaded (100%) and the second square has 73 squares shaded (73%), so 100 + 73= 173%
Hope this helped! :)
Answer:
The function f(x) = 1/5x2 – 5x + 12 is a quadratic function, because the higher exponent is 2.
The correct statements are:
- The value of f(-10) = 82
- The graph of the function is a parabola
- The graph contains the point (20,-8)
Step-by-step explanation:
- The value of f(-10) = 1/5(-10)2 – 5(-10) + 12 = 1/5(100)+50+12 = 82 (<em>True</em> s<em>tatement</em>).
- The graph of the function is a parabola, as all the quadratic functions. (<em>True</em> s<em>tatement).</em>
- The graph of the function opens down: The parabola opens up or down depending on the "a". It is the important part of the function that determines whether it opens up or down, the parabola will open up when "a" is greater than zero.
When "a" is smaller than zero the parabola will open down. In our example a = 1/5 (greater than zero, so the parabola opens up). <em>(False Statement)</em>
- The graph contains the point (20,-8). For f(20) = 1/5(20)2 - 5(20) +12 = 1/5(400) - 100 + 12 = 80 - 100 + 12 = -8 <em>(True Statement).</em>
- The graph contains the point (0,0). For f(0) = 1/5(0)2 - 5(0) + 12 = 12, the correct point is (0,12) <em>(False Statement)</em>.
The answer should be 2+5+n.
Answer:
20x
Step-by-step explanation:
A certain map scale in which 1/2 inch on the map represents an actual distance of 10 miles. A distance of x miles is represented by how many inches on this map?
From the above question:
1/2 inch = 10 miles
x inches = m
Cross Multiply
1/2m = 10x
m = 10x ÷ 1/2
m = 10x × 2
m = 20x
