Hi there! The answer is 102 mph.
A car travels at a steady speed and takes 5 hours to travel 510 miles.
To work out the average speed, we only need to find the speed per hour (miles per hour - mph). Since we now have our distance covered in 5 hours, we must divide by 5.
Distance covered per hour = 510 miles / 5 hours = 102 miles per hour.
Therefore the speed is 102 mph.
Answer:
32x² + 36x + 9
Explanation:
To answer the question, we will simply multiply each term from the first bracket by each term from the second bracket and then combine like terms to get the final expression.
This can be done as follows:
(8x + 3)(4x + 3)
8x(4x) + 8x(3) + 3(4x) + 3(3)
32x² + 24x + 12x + 9
32x² + 36x + 9
Hope this helps :)
The correct equation is P(t) = Po*e^(kt). Please enclose "kt" inside parentheses and use the " ^ " symbol to indicate exponentiation.
"k" is the growth constant, which here is 0.017. "t" is the number of yeasrs. P(7) is the population after 7 years. Po is the initial population, which in this case is 91 million.
The initial value, when t = 0, is 91 million.
After 7 years, the population, P(7), was P(7) = (91 million)*e^(0.017*7). This evaluates to P(7) = (91 million)*(1.070) = 96 million
Answer:
Step-by-step explanation:
The first step to solving this problem is verifying if this sequence is an arithmetic sequence or a geometric sequence.
This sequence is arithmetic if:
We have that:
This is not an arithmetic sequence.
This sequence is geometric if:
This is a geometric sequence, in which:
The first term is 40, so 
The common ratio is 
, so 
.
We have that:
The 10th term is 
. So:
Simplifying by 4, we have:
You have to use the formula cost over quantity
Divide 8 and $2.88
The answer is.
0.36
