The graph shown depicts the path of a line drive baseball hit during practice. the x-axis is time (in seconds) and the y-axis is the height of the ball (in meters). at what time did the ball reach its maximum height, and how long was the ball in the air?

a. 5 seconds, 2 seconds
b. 2 seconds, 5 seconds
c. 2 seconds, 4 seconds
d. 2.3 seconds, 5 seconds

B. 2 seconds, 5 seconds

Step-by-step explanation:

Looking at the graph, you can see that the vertex, or the point where the graph is at it's highest point, is at 2 seconds and a little over 2 meters in height.  So, the time the ball reached it's maximum height was 2 seconds.  Looking at the x-axis, which shows the overall time of the ball in the air, you see the ball does not reaching the ground (0 meters) until 5 seconds, so the total time in the air is 5 seconds.  

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
