Answer:is there another triangle or is it just that one?
Step-by-step explanation:
Check the picture below
make sure your calculator is in Degree mode.
To find the perimeter of a triangle you simply add up all the sides. Because your possible answers are in fractions, I would convert the decimal values into fractions.
2.2 becomes 2 & 1/5
3.25 becomes 3 &1/4
1 & 5/6 is already a fraction, so you can leave it as it is. To combine these you need to find a common denominator (here it is 60). *It may help to convert the mixed numbers to improper fractions to add them, which is what I did*
You get:
132/60 + 110/60 + 195/60
When you add all that up you get 437/60, which is 7&17/60, so D
I know that was long and wordy, but I hope I helped!!
Answer: d. s=16-t²
Step-by-step explanation: the answer is s=16-t², because for this case is really important to keep in mind which is the value with the quadratic expression, when we have a quadratic expression the graphic representation will be a parabola, in a parabola you will find a point that never change which is constant in the diagram.
also keep in mind that the values which are placed in the axis of the ordinates are the independent variables and in parabola the quadratic values are placed in the axis of the ordinates , and for this case is t² because of the quadratic expression, then we can find that t² is the independent variable and s is the dependent variable.
