$76.5
51/6 = 8.5
8.5 x 9 = 76.5
Answer:
1/4
Step-by-step explanation:
coins have 2 sides, tails and heads, so for it to land on tails is a 1/2 chance. Dice have 6 sides and 1,3,5 are all odd so its a 3/6 chance. Simplify 3/6 to 1/2 and multiply by 1/2 to get 1/4. im not sure, its my guess.
Answer: 4 seconds
Step-by-step explanation:
Given: The function
can be used to model the height of the ball where t is the time in seconds after the ball kicked and h(t) is the height in feet.
Differentiate the given function with respect to t , we get

Put h'(t)=0

Also, 
By second derivative test, h(t) is maximum at t=4.
Hence, the time in Devon which the ball reaches it maximum height = 4 seconds
<h2>
Answer:</h2>
A pyramid is a polyhedron where the base is a polygon and whose lateral faces are all triangles. So a triangular pyramid is a pyramid that has a triangular base. The definition of a solid tells us that this is a three-dimensional shape. The figure below shows a triangular pyramid, so you can see that:
- This triangular pyramid has 4 faces
- The solid has 3 side faces and all are triangles
- The base is also a triangle
- This pyramid has 4 vertices
- It has 6 edges
Answer:
Choice A.
Step-by-step explanation:
Apply the vertical line test.
If a vertical line intersects 2 or more points on the graph, the relation is not a function.
If all vertical lines intersect at most 1 point on the graph, the relation is a function.
Any vertical line in Choice A. intersects 1 single point. Choice A. is a function.
There are vertical lines that would intersect 2 points of the graph in Choices B., C., and D., so they are not functions.
