At 1 hour the ship traveled 25 miles.
At constant speed, this means every 1 hour the ship travels 25 miles.
The speed would be 25 miles per hour.
Don't modify the equation. It is true that f(3)= 288 for f(t) = -16t^2 +144t
the maximum height of the ball will be where the derivative is zero. In other words you could find the height of the ball by converting this into vertex form, or you could find it by calculating the time needed for the ball to reach its maximum height.
0=-32t+144
t=3 till max and max is 288
224=-16t^2 +144t
0= -16t^2+144t-224
t=2 but then the ball will reach 224 ft again at t=7
the ball reaches its maximum height at t=3 seconds and a parabola is symmetric, so at t=6 seconds it will contact the ground again.
Answer:
-4/3
Step-by-step explanation:
:P
To solve a proof, you need to distinguish which is the hypothesis and which is the conclusion. The hypothesis is the starting point and the conclusion is the ending point. We go from hypothesis to conclusion. A conditional statement can be written as If A, then B. Where A is the hypothesis and B is the conclusion.
For example, take this theorem.
If two sides of a triangle<span> are congruent, then the angles opposite those sides are congruent.
</span>
We go from Two sides of a triangle are congruent to the angles opposite those sides are congruent.
The first statement's reason is pretty much always Given.
Statement | Reason
1. Two sides of a triangle are congruent 1. Given
.... After a bunch of steps
3. the angles opposite those sides are congruent. 3. Your postulate of definition of what reason you need to complete the last step.
Sorry if this is a little confusing.
