3. If an object is dropped from a height of 100 ft, the function h(t) = -16f+

Mathematics
1 answer:
Sliva [168]3 years ago
7 0

Answer:

When t = 25/4 the object his the ground.

Step-by-step explanation:

When the object hit the ground, the distance from it to the ground (or height) will be 0.

Thus,

if when the object touch the ground is when h = 0 then h(t) = 0

So we can set up this equation :

0 = -16t + 100

-100 = - 16t

-100/-16= 25/4 = t

The contrapositive of a conditional statement is "If an item is not worth five dimes, then it is not worth two quarters.”
balandron [24]
Example of use of terms:
Statement:  If it is far, we take a bus.
Inverse:       If it is not far, we do not take a bus.
Converse:   If we take a bus, it is far.
Contrapositive:  If we do not take a bus, it is not far.

We also know that
1. The inverse of the inverse is the statement itself, and similarly for converse and contrapositive.
2. Only the contrapositive is logically equivalent to the original statement.
This means that the converse and inverse are logically different from the original statement.

Now back to the given statement.
To find the original statement, we find the contrapositive of the contrapositive.
We then find the converse from the original statement, as in the example above.

Original statement
(note that in English, if it is not worth X dollars, means if it is not worth AT LEAST X dollars")
contrapositive of 
<span>
"If an item is not worth five dimes, then it is not worth two quarters.”
is the negation of the converse, which become
"If an item is worth two quarters, then it is worth (at least) five dimes."


The converse of the previous statement is therefore
"If an item is worth (at least) five dimes then it is worth two quarters"

In this particular case, we can also take advantage of the fact that the contrapositive is the negation of the converse.  So all we have to do is the provide the negation of each component of the contrapositive to get the converse:
"If an item is worth (at least) five dimes, then it is worth two quarters".
as before.

Note that the converse does NOT logically mean the same as the original statement.

Which statements about the graph of f(x) =√x are true?
marshall27 [118]

Answer:

Step-by-step explanation:

So let's think about what values you can take square root of...

anything but negative values!

So the first one is not correct because you can also take square root of 0,

squareroot of 0 is 0.

So because of this, C and D are both correct, E is correct because root  x is an increasing function. B is incorrect because (0,0) is an intercept.
