Answer:

The vertex form of the quadratic function, f(x) = a·(x - h)² + k

Step-by-step explanation:

The general form of a quadratic function is given as follows;

f(x) = a·x² + b·x + c

The vertex form of the quadratic function is f(x) = a·(x - h)² + k

Where;

(h, k) = The coordinates of the vertex of the parabola

h = -b/2·a, k = f(h)

ANTONII [103]

Answer:

9670 feet

Step-by-step explanation:

The height given (8219.5 ft) is 85% OF ORIGINAL, hence original is much higher. But how do we figure this out?

we translate word problem to equation.

8219.5 IS 85% of TOTAL

Firstly, 85% = 85/100 = 0.85

Remember, is means =

of means multiplication

So we have:

8219.5 = 0.85 * Total

Hence, total = [let total be 7]

8219.5 = 0.85 * t

t = 8219.5/0.85 = 9670 feet

Work out the number of sides tile A has.<br> Both tile A and tile B are regular polygons
finlep [7]

Answer:

12

Step-by-step explanation:

since tile B is a regular polygon means it is an equilateral triangle. The angle inside B would be  60.

(360 - 60)/2 = 150 (interior angle of tile A)

180 - 150 = 30 (exterior angle of tile A)

therefore number of sides = 360 /30 = 12

Let the measure of an angle be 'x'
Then the reflex angle will be measured by the formula (360-x)
x +(360-x) = 360
