Answer:

x = 9.9 in.

Step-by-step explanation:

area of triangle = base * height /2

49 = x*x /2

49*2 = x^2

\sqrt{98} = x

7\sqrt{2} = x

4. Don designed a triangular-shaped garden. Use the diagram to answer each question.
mote1985 [20]
This is a 45-45-90 triangle or a right triangle created by the sides.

Because of this being a right triangle and 45 degrees being given already for one angle you would add 90 and 45 which will give you 135. You would subtract 135 from 180 because all the angles of a triangle add up to 180°. 180-135=45. X=45°

       (number of ways it can come out the way you want it to)
divided by
       (total number of ways it can come out).

Total number of ways it can come out =

                    number of bottles in the cooler

                 = (10 + 15 + 13) = 38 .

Number of ways it can come out the way you want it to =

                   (soda + lemonade)

                = (10 + 15) = 25 .

Probability of coming out the way you want it to =

                     25 / 38  =  about 65.8 % .

State the value of the discriminant for <br><br>y = <img src="https://tex.z-dn.net/?f=5x%5E2%2B9x-3" id="TexFormula1" title="5x^
Nostrana [21]

Answer:

141, meaning that there will be two real solutions

Step-by-step explanation:

The discriminant of a quadratic is b^2-4ac, which in this case is:

9^2-4(5)(-3)=81+60=141

Since the discriminant is positive and not zero, there will be two real solutions to this equation. This is because when the discriminant is negative, and you take the square root of it, you get a negative number. If you take the square root of 0, you get 0, which means that there will only be one solution to the equation.

Hope this helps!
