The median is 11. Hope this helps!
Answer:
none
Step-by-step explanation:
y = -4x^2 +3x-2
To find the x intercepts, let y =0
0 = -4x^2 +3x-2
Using the discriminant
a=-4, b=3 c=-2
b^2 -4ac
3^2 -4(-4)(-2)
9 -32
-23
Since this is negative all the roots are complex, so it has no real roots
none
Answer: The equation shall be
8 = 4W
Step-by-step explanation: The perimeter has been given as 46 feet, whereas the length and the width are not yet given. But the clue we have states that “the length is 19 feet longer than the width,” which means, if the width is W then the length shall be 19 plus W. We can express the dimensions as;
Length = 19 + W
Width = W
We can now express the perimeter as follows;
Perimeter = 2(L + W)
46 = 2(19 + W + W)
46 = 2(19 + 2W)
46 = 38 + 4W
Subtract 38 from both sides of the equation
8 = 4W
Answer:
2nd graph
Step-by-step explanation:
Given
f(x) = x² + 3x - 4
To find the zeros let f(x) = 0 , that is
x² + 3x - 4 = 0 ← in standard form
(x + 4)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x - 1 = 0 ⇒ x = 1
The only graph with zeros at x = - 4 and x = 1 is the 2nd graph
