Answer:
4 seconds
Step-by-step explanation:
where h=height reached after t seconds
= Initial Height of the ball
The ball is dropped from a height of 205 feet,
= 205 feet
We want to determine the time it takes the ball to reach the ground.
i.e. when height of the ball, h=0
Substituting = 205 feet and h=0 into the formula
Add to both sides
Divide both sides by 16
≈ 4 Seconds
It takes approximately 4 seconds for the ball to reach the ground.
The value of the x-coordinate when the y-coordinate is 0 is given below.
Step-by-step explanation:
- The point in which the graph crosses the x-axis is called the x-intercept and the point in which the graph crosses the y-axis is called the y-intercept. The x-intercept is found by finding the value of x when y = 0, (x, 0), and the y-intercept is found by finding the value of y when x = 0, (0, y).
- The intercepts of a line are the points where the line intercepts, or crosses, the horizontal and vertical axes.
The straight line on the graph below intercepts the two coordinate axes. The point where the line crosses the x-axis is called the [x-intercept]. The [y-intercept] is the point where the line crosses the y-axis. the y-intercept occurs where x = 0, and the x-intercept occurs where y = 0.
- The y-intercept occurs where x = 0, and the x-intercept occurs where y = 0.The horizontal axis is called the x-axis and the vertical axis is called the y-axis
.The center of the coordinate system (where the lines intersect) is called the origin. The axes intersect when both x and y are zero. The coordinates of the origin are (0, 0).
An ordered pair contains the coordinates of one point in the coordinate system. A point is named by its ordered pair of the form of (x, y). The first number corresponds to the x-coordinate and the second to the y-coordinate.
Answer:
Height of parallelogram = 5.07 inches
Step-by-step explanation:
We are given Area of Parallelogram = 32 in^2
Height of Parallelogram = ?
Base of Parallelogram = 6.3 in
The formula to find the Area of Parallelogram is:
Area of Parallelogram = Base * Height
32 = 6.3 * Height
=> Height = 32/6.3
=> Height = 5.07 inches
So, height of parallelogram = 5.07 inches
Answer:
Point above the line is an outlier
Step-by-step explanation:
If the point is above the given line then it is clear that it does not fit the best fit curve (which is in this case is the line represented by equation y=4.413x+0.377)
Point above this line means that the point is an outlier which does not fit the curve.
Finde the difference between each one:
d = A2 - a1 = 4-2 = 2
sequence formula:
an = a1 + (n-1) *d
a10 = 2 + (10-1) * 2
a10 = 2+9 *2
a10 = 2+18
a10 = 20
The answer is D.
