we are given
we are given relation between speed and distance
distance ( when speed =70mph) is
=328feet
so, 
distance ( when speed =50mph) is
=183feet
so, 
now, we can find percentage in decrease
now, we can plug values
%...........Answer
Answer:
V=1,840in
Step-by-step explanation:
divide the shape into 2 rectangles V=l x w x h find the volume for the 2 rectangles and then add the answers
5x8x10=400
20x8x9=1,440
400+1,440=1,840in
Answer:
Step-by-step explanation:
The position equation is given as
and we are looking for the times when the position of the ball is 9 feet. That means that we simply plug in a 9 for s(t) and factor to solve for t:
and
and this is what we factor to find t:
t = .42 sec and then again on its way back down at t = .89 sec
Using the function concept, it is found that this sequence is a function because it passes the vertical line test.
A function relates <u>each value of the input to one value of the output</u>, hence, option b is incorrect.
- On a graph, each value of x(horizontal axis) is mapped to a value of y(vertical axis), hence, a vertical line test can be applied to determine whether the relation is a function.
In this problem:
- For each day, there is only one output, which is her balance, hence, it passes the vertical line test.

Answer:
6 goldfish = $4.50. You can buy 66 goldfish with $50
Step-by-step explanation:
We know that dozen is 12, so 12 goldfish would be $9. To find how much one goldfish costs we would divide 9 and 12. 9÷12 is 0.75. So one goldfish is $0.75.
To find 6 goldfish just multiply 0.75 to 6. 6 goldfish would be $4.50.
We know that 0.75 times 100 would be 75 so you can only buy less than 100 goldfishes. You can buy 66 goldfishes with $50.
If this helped, I would appreciate it if you marked me brainliest. Have a nice day!
