Answer:Given that the graph shows tha the functión at x = 0 is below the y-axis, the constant term of the function has to be negative. This leaves us two possibilities:
y = 8x^2 + 2x - 5 and y = 2x^2 + 8x - 5
To try to discard one of them, let us use the vertex, which is at x = -2.
With y = 8x^2 + 2x - 5, you get y = 8(-2)^2 + 2(-2) - 5 = 32 - 4 - 5 = 23 , which is not the y-coordinate of the vertex of the curve of the graph.
Test the other equation, y = 2x^2 + 8x - 5 = 2(-2)^2 + 8(-2) - 5 = 8 - 16 - 5 = -13, which is exactly the y-coordinate of the function graphed.
Step-by-step explanation:
1) Write 3% as 3/100
2) Since, finding the fraction of a number is same as multiplying the fraction with the number, we have:
of 2500 = × 2500
Therefore, the answer is 75
If you are using a calculator, simply enter 3÷100×2500 which will give you 75 as the answer.
Commission = $75
Answer:
B, 150
Step-by-step explanation:
use pythagorean theorem, the sides of the triangle are 120 and 90, so when u square them and add them together, you get 120^2 +90^2 = 22500
square root 22500 to find the hypotanuse which is the length from one corner to another. the anwser is 150m which is b
