An object is launched from a platform.

Mathematics
1 answer:
Bess [88]4 years ago

Answer:

60 feet

Step-by-step explanation:

The height, h (in meters), of the object launched from a platform is represented by the equation

h=h(x)=-5x^2+20x+60

where x is the time (in seconds) passed after the launch.

The time of launch is x=0 (0 seconds passed after the launch)

Substitute x=0 to find the height:

h=h(0)=-5\cdot 0^2+20\cdot 0+60=60\ feet

Draw and shade figures that represent 50%, 25%, and 150%. Label each figure and described it in words. How do I answer this ques
muminat
See photo for drawing. 
Words: 
Suppose a square is 100%, 
50%: the square is divided into two equal parts, and one of them is shaded, therefore it is 50%. 
25%: the square is divided into 4 equal parts, and one of them is shaded, therefore it is 25%. 
150%: there are two squares, each divided into 2 equal parts, and 3 of them is shadowed, therefore it is 150%.

Answer:

The answer to your question is the third option

Step-by-step explanation:

To know if two lines are parallel we must get their slopes if the slopes are equal, the lines are parallel.

Data

A (2,2)

B (3,6)

C(0,5)

D(1,9)

Formula

slope = \frac{y2 - y1}{x2 - x1}

Process

1.- Calculate the slope of line 1

slope 1 = \frac{6 - 2}{3 - 2}

slope 1 = \frac{4}{1}

slope 1 = 4

2.- Calculate slope 2

slope 2 = \frac{9 - 5}{1 - 0}

slope 2 = \frac{4}{1}

slope 2 = 4

3.- Compare the slope

slope 1 = 4 and slope 2 = 4, both slope are equals, then the lines are parallel.

Answer:

The other point on the diameter which is also on the circle is; (-3, 2)

Step-by-step explanation:

The center of the circle, also a point where the diameter crosses, is (3, 6)

The diameter touches the circle at point (9, 10)

The displacement is (9 - 3, 10 - 6) = (6, 4)

This means that we move, +6 units along the x-axis and +4 units along the y-axis , from the center of the circle in order to reach point (9, 10)

If we want to reach the other point on the diameter which also on the circle, we move -6 units along the x-axis and -4 units along the y-axis to get;

(3, 6) - (6, 4) = (-3, 2)
