Answer:
1
Step-by-step explanation:
The given equation of the function is y = -a·(x - h)² + 1
The positive constants of the equation = <em>a</em>, and <em>h</em>
The points the function crosses the x-axis = 2, and 4
Where the function crosses the x-axis, y = 0, and x = 2, and 4, therefore, when x = 2, we have;
y = 0 = -a·(2 - h)² + 1
When x = 4, we have;
0 = -a·(4 - h)² + 1
-a·(2 - h)² + 1 = -a·(4 - h)² + 1
-a·(2 - h)² = -a·(4 - h)²
(2 - h)² = (4 - h)²
±(2 - h) = +#±(4 - h)
When
(2 - h) is negative, and (4 - h) is positive, but the same magnitude, we have';
-(2 - h) = +(4 - h)
2·h = 4 + 2 = 6
h = 3
0 = -a·(4 - h)² + 1 = -a·(4 - 3)² + 1 = -a + 1
Therefore, a = 1
Answer:
4 flowers
Step-by-step explanation:
First we need to calculate the circumference of the plate.
C = πd
Given
diameter d = 20cm
C = 3.14(20)
C = 62.8 cm
If there is a flower painted every 15.7 centimeters around the edge of the plate, the amount of flower on the plate will be;
Number of flower = Circumference of the plate/length of flower
Amount of flower = 62.8/15.7
Amount of flower = 4
Hence there are 4 flowers painted on the plate

Answer:
wait do u have a word bank or anything like words to go with it or numbers ????
Answer: a) x= 68, b) 108°, c) 72°, d) 255°.
Step-by-step explanation:
Since we have given that
The interior angles of hexagon:
(2x+17), (3x - 25), (2x+49), (x+40), (4x-17) and (3x - 4).
So, it becomes :
ii. Find the smallest interior angle of the quadrilateral.
iii. Find the largest exterior angle of the quadrilateral.
iv. Find the largest interior angle of the quadrilateral.
Hence, a) x= 68, b) 108°, c) 72°, d) 255°.
