Answer:

Step-by-step explanation:

The zeros are the values of x for which y = 0

Quadratic formula

x = [5 ± √(5² – 4·1·6)] / [2·1]

= [5 ± √1] / 2

= [5 ± 1] /2

= 2, 3

sum of zeros = 5

igor_vitrenko [27]

Answer:

113.04 feet²

Step-by-step explanation:

Use the circle area formula, A = $\pi$ r²

Sine the diameter is 12 feet, the radius is 6 feet

Plug in 6 as r into the formula, and 3.14 as pi, then solve:

A = $\pi$ r²

A = (3.14)(6²)

A = (3.14)(36)

A = 113.04

So, the area of the circle is approximately 113.04 feet²

Answer:

The gradient of the graph below is $\mathbf{\frac{3}{2} }$

Step-by-step explanation:

We need to calculate the gradient of the graph

The gradient of graph is actually slope of the graph.

The slope of graph can be calculated using formula: $Slope=\frac{y_2-y_1}{x_2-x_1}$

Taking any 2 points on graph i.e

(1,0) and (-1,-3)

We have $x_1=1, y_1=0, x_2=-1,y_2=-3$

Putting values and finding gradient:

$Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-3-0}{-1-1}\\Slope=\frac{-3}{-2}\\Slope=\frac{3}{2}$

So, The gradient of the graph below is $\mathbf{\frac{3}{2} }$
