Answer:
A. Discriminant = 116
B. Number of solutions for the quadratic equation = 2
C. Type of solutions (circle one):Imaginary
D. Type of solutions (circle one):irrational
Step-by-step explanation:
The given quadratic equation is
We rewrite in standard form to get;
The discriminant is
where a=1, b=8, c=-13
We substitute to get:
Since the discriminant is great than zero, we have two distinct real roots
Answer:
15
Step-by-step explanation:
Subtract 1.5r from both sides of the equation and you get ...
15 = r

Answer:
x=0, y=-2
Step-by-step explanation:
Let x=3y+6 be equation 1
and 2x-4y=8 be equation 2
sub equation 1 into equation2,
2(3y+6)-4y=8
6y+12-4y=8
2y=-4
y=-2
sub y=-2 into equation 1,
x=3(-2)+6
x=0
sub is an abbreviation for substitute
Answer: 1) 530.66 ft^2
Step-by-step explanation:
You need to find the area of the circles.
They gave you the formula to find them which is
Area = Pi * R^2 //// Pi times Radius squared will give you the area.
For example, the radius of the 1st question is 13ft. We use it with the formula given.
A = 3.14 * 13^2 /// 13 squared is just 13 x 13 = 169
A = 3.14 * 169 /// Now multiply Pi times 169
A = 530.66 /// Thats your answer.
530.66 ft^2
