Answer:
Time = 149.688 seconds
Step-by-step explanation:
First the conversation rate of ft to miles is
1 foot = 0.000189 mile
So 3300 feet = 3300*0.000189
= 0.6237
3300 feet = 0.6237 mile
So the roller coaster traveled 0.6237 mile.
But the speed of the roller coaster is 15 mile/hour
To calculate for time
Speed = distance/time
Time = distance/speed
Time = 0.6237/15
Time = 0.04158 hour
Converting to seconds , we multiply time by 3600
Time in seconds = 0.04158*3600
Time = 149.688 seconds
Thank you
I dont understand the question?
to co.plete the square you have x2-10x+25+y2-14y+49=7+25+49 where 7+25+49 is the radius and -5,-7 is the center
Answer:
x = 3.556 or ![\frac{32}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B32%7D%7B9%7D)
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:
(3*x-5)^2-((x+x+25))=0
Evaluate:
= ![9x^{2} -30x+25](https://tex.z-dn.net/?f=9x%5E%7B2%7D%20-30x%2B25)
Pull like factors:
9x^2 - 32x = x • (9x - 32)
x • (9x - 32) = 0
Remember roots of a product:
A product of several terms equals zero. When a product of two or more terms equals zero, then at least one of the terms must be zero. We shall now solve each term = 0 separately. In other words, we are going to solve as many equations as there are terms in the product. Any solution of term = 0 solves product = 0 as well.
Solve : 9x - 32 = 0
Add 32 to both sides of the equation :
9x = 32
Divide both sides of the equation by 9:
x = 32/9 = 3.556
