Answer:
Wrong: Linear functions, cubic functions
Step-by-step explanation:
Both can decrease. Cubic functions nearly always decrease at some point and, if there is a negative slope, linear functions can decrease as well.
Answer:

Step-by-step explanation:
A rectangle is a closed planer quadrilateral with four right angles and its opposite sides are the same length. The fence around it including the gates is 200 feet long, so basically they are providing the perimeter of the rectangle. The perimeter of a rectangle is equal to the sum of all its sides. Hence:

The ectangular playground is 40 feet wide, so:

Therefore:

Solving for h:

The area of a rectangle is equal to the product of two of its contiguous sides, hence:

I attached you a picture of the rectangle

Answer:
cos(x) = 0.6
Step-by-step explanation:
First, we need to find UQ.
UQ = UP·cos(y°) = UP·√(1 -sin²(y°)) = (26 cm)√(1 -25/169) = (26 cm)(12/13)
UQ = 24 cm
Then TQ is ...
TQ = 1/3UQ = 1/3(24 cm) = 8 cm
And cos(x°) is ...
cos(x°) = √(1 -sin²(x)) = √(1 -64/100)
cos(x°) = 6/10 = 3/5
cos(x°) = 3/5 = 0.6
Answer : The Susana swam the fastest.
Step-by-step explanation :
Speed : It is defined as the distance traveled per unit time.
Formula used :

First we have to determine speed of the following persons.
<u>For Tawni :</u>
Distance = 50 m
Time = 40.8 s

The speed of Tawni is, 1.225 m/s
<u>For Pepita :</u>
Distance = 100 m
Time = 60.2 s

The speed of Pepita is, 1.661 m/s
<u>For Susana :</u>
Distance = 200 m
Time = 112.4 s

The speed of Susana is, 1.779 m/s
From this we conclude that, in this problem meter affects the response and the speed of Susana is more than the Pepita and Tawani.
Thus, Susana swam the fastest.
