11. What is the location of the vertex of the parabola defined by f(x) = −3x2 − 18x − 35 and in what direction does the parabola

lbvjy [14]

11. The given parabola has equation: $f(x)=-3x^2-18x-35$

We complete the square to have the function in the vertex form: $f(x)=-3(x^2+6x)-35$

$f(x)=-3(x^2+6x+9)+3*9-35$

$f(x)=-3(x^2+6x+9)+27-35$

$f(x)=-3(x+3)^2-8$

The vertex is (-3,-8), the graph opens down because a=-3<0

Ans: B. Vertex: (−3, −8), opens downward

12. We know the graph of $y=x^2$ is a parabola that opens up and has its minimum point at the origin.

The range of this function is $y\ge 0$

A straight line that has its y-intercept below the x-axis (y=3x-6) will not intersect $y=x^2$ and hence will form a system with no solution.

Ans: D. y equals x squared, y equals 3x minus 6

14. We want to find the zeros of $x^2+21x=5x-63$

$x^2+21x-5x+63=0$

$x^2+16x+63=0$

The factored form is $(x+7)(x+9)=0$

$x=-7\:or\: x=-9$

Ans: C. x = −7, −9

15. The given quadratic expression is $6x^2-17x+10$

We split the middle term to obtain:

$6x^2-12x-5x+10=0$

We factor by grouping to get:

$6x(x-2)-5(x-2)=0$

$(x-2)(6x-5)=0$

Ans: D. 6x − 5

Two gardens are being fenced in. Both gardens will require the same amount of fencing (both gardens have the same perimeter in

Tresset [83]

Answer:

Dimensions of the square garden = 9 meters by 9 meters

Dimensions of the triangular garden = 12 meters

Step-by-step explanation:

Let the measure of a side of the square garden = x meters

Perimeter of the square = 4x meters

Since each side of the triangle is 3 meters longer than each side of the square, side of the triangle will measure = (x + 3)

Perimeter of the equilateral triangle = 3(x + 3) meters

Perimeter of the square = perimeter of equilateral triangle

4x = 3(x + 3)

4x = 3x + 9

4x - 3x = 9

x = 9 meters

Dimensions of the square garden = 9 meters by 9 meters

Dimensions of the triangular garden = 12 meters
