C is the only logical answer here. The slope of 6 represents how many trees are planted a year, while 4 represents the starting number.
Once put into the quadratic formula the numbers in the square root of they are negative no solutions if it is 0 then 1 solution if more then more than one solution
Answer:
- The surface area of the sphere in terms of r is 4πr^2 square units.
- The surface area of the cylinder in terms of r is 4πr^2 square units.
- The surface area of the cylinder and sphere are the same.
Step-by-step explanation:
The surface area of the sphere is given by the formula ...
A = 4πr^2
The surface area of the cylinder is given by the formula ...
A = 2πr^2 +2πrh
Here, the height (h) is equal to r, so this simplifies to ...
A = 2πr^2 +2πr·r = 4πr^2 . . . . . the same area as the sphere
If the two buses are 640 miles apart after 5 hours. Then the rate of each bus will be 57 miles per hour and 71 miles per hour.
<h3>What is speed?</h3>
The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
Two buses leave a station at the same time and travel in opposite directions.
One bus travels 14 miles faster than the other.
Let x be the speed of first bus. Then the speed of the second bus will be (x + 14).
If the two buses are 640 miles apart after 5 hours.
Then the rate of each bus will be
Then the relative speed of the buses will be
S = x + x + 14
S = 2x + 14
Then the value of x will be
2x + 14 = 640 / 5
2x + 14 = 128
2x = 114
x = 57 miles per hour
Then the speed of the other bus will be
⇒ 57 + 14
⇒ 71 miles per hour

9.26>.926, because 9.26 has a whole number and .926 is just thousandths which is smaller. Hope I helped! :-)
