Answer:Corey was travelling at 9 miles per hour and Tom was travelling at 13 miles per hour.
Step-by-step explanation:
Let x represent Corey's speed.
If Tom travels 4 mph faster than Corey, it means that Tom's speed would be (x + 4) mph
Corey is 176 miles from Tom and they are traveling towards each other. If they meet after 8 hours, it means that they travelled a total distance of 176 miles in 8 hours.
Distance = speed × time
Distance travelled by Corey in 8 hours would be
8 × x = 8x miles
Distance travelled by Tom in 8 hours would be
8(x + 4) = (8x + 32) miles
Since the total distance travelled by Tom and Corey is 176 miles, then
8x + 8x + 32 = 176
16x = 176 - 32 = 144
x = 144/16 = 9 miles per hour
Tom's speed would be
9 + 4 = 13 miles per hour
To find the length of the 3rd side, you would use the pythagorean theorem
a^2 + b^2 = c^2
132^2 + b^2 = 157^2
17424 + b^2 = 24649
b^2 = 7225
b = square root of 7225
<span>D. It is incorrect because the length of the unknown side is the square root of 7,225.</span>
Hey there!
First, set up an exponential equation that represents the rate at which your original amount, 1000, gains interest:
y = 1000(1.24)^x
Y represents the value after X years. 1.24 represents the rate at which the money gains interest, 1 + 0.24 (your 24% interest rate in decimal form). 1000 is your original amount.
Now, set this equation equal to 64000, graph y = 64000 and y = 1000(1.24)^x on a graphing calculator, and see where the two equations intersect in order to solve for x.
They intersect when x is about 19.334, as seen in the graph below (it is very zoomed in so that you can see where the two functions intersect). Therefore, it will be about 19 years after the year in which you deposited the 1000 dollars before the money is worth 64000 dollars.
