Step-by-step explanation:
We must realise that the image of the quadratic curve shown is not showing the full curve. Instead it extends further out.
For all quadratic curves, the domain is all x-values.
We see here that this quadratic curve has an absolute minimum at y = -4 and the curve stretches towards positive infinity.
Hence the range is y >= 4.
The correct answers are the 1st and 5th options.
Answer:
6 days
Step-by-step explanation:
You have to subtract 25.5 from 76.5 and divide that number by 8.5.
66.5 square centimeters.
Start by separating the figure into a triangle and a rectangle.
We know the base of the triangle is 7 cm, so find the height by subtracting the total height of the figure by the height of the rectangle. 11 cm - 8 cm = 3 cm
Now, find the area of each shape. The area of a rectangle is length (base) times width (height). This is 7 cm * 8 cm, or 56 cm^2.
Then, find the area of the triangle. The area of a triangle is base times height times 1/2. So, it is 7 cm * 3 cm * 1/2.
21 cm^2 * 1/2
10.5 cm^2
Finally, add the areas together. 56 cm^2 + 10.5 cm^2 = 66.5 cm^2
