Answer 1

Answer:

a. True

b. False

c. True

d. True

e. False

f. True

g. False

h. True

i. True

j. True

Step-by-step explanation:

The statement a and i are true. The predicates can be defined without an input variable. These numerical variables can be defined without an input variable. The statement b is false since the p to q is not in conjunction rather its contradiction.

Answer:

slope = 10/1

Step-by-step explanation:

slope is the vertical rise over the horizontal rise

if you select two points on the line -- I used (10, 0) and (20, 20) -- and subtract the y-values you will get the vertical rise (20 - 0 = 20); if you now subtract the x-values (20 - 10 = 10) you will get the horizontal rise

so, 20/10 or 10/1

if you go from point (10, 0) to (20, 20) then you go up by 10 and over to the right by 1

Answers

Answer:

The function f is graphed.

f is an even function as it has U- form.

As per the graph there is one local maximum at (0, 4) and one local minimum at (6, 1).

The global minimum is (-9, -2) and the global maximum is infinity.

The minimum and maximums are the borders of the increasing or decreasing intervals.

If you divide both sides of your inequality by five, you see that k must be less than 9

k < 9 that is equivalent.

You can make another equivalent inequality by multiplying both sides by 3.

3k < 27

Answer:

-1, 4, 6, 8

k<9

Step-by-step explanation:

Two ways to do this

One is to substitute the values in for k and then see if the inequality is still true.

-1, 4, 6, 8, when substituted in for k and then multiplied by 5, will be less then 45.

9, however, does not work because 9 times 5 is 45, which makes the inequality untrue. So, k has to be less than 9.

The faster, more mathematical way is to divide both sides by 5. 5 divided by 5 is 1 and 45 divided by 5 is 9, so the new inequality would be k<9.

if i walk 120 meters per minute slower than i cycle. my cycling speed is 3 times faster than my walking. What is my walking speed. meters per minute

Answers

Answer:

His walking speed is 60 meters per minute.

Step-by-step explanation:

Given that the person walks 120 meters per minute slower than he cycles, and his cycling speed is 3 times faster than his walking, in order to known his walking speed in meter per minute, the following logical reasoning has to be made:

The person walks 120 meters per minute slower than he rides a bicycle, and in turn, rides a bicycle three times faster than he walks. Therefore, those 120 meters per minute is 2/3 of his speed on a bicycle, which makes up the remaining third with the speed at which he walks. Thus, since 120/2 is 60, and 60 x 3 is 180, the person walks at 60 meters per minute, and bicycles at 180 meters per minute.
