Answer:
Option (a).
Step-by-step explanation:
1) Pedro decided to build a rectangular enclosure with an area of 36 m². How many meters of canvas will he have to buy to make the enclosure considering that one side will be 3 meters more than the other?
Let the length of the rectangle be x then the width will be (3+x) m
The area of a rectangular enclosure is 36 m².
To find how may meter of canvas will he have to buy to make the enclosure, we can find its perimeter. Firstly finding length and breadth using formula of area of rectangle.
Neglecting negative value, we get the length is 4.64 m
Width, b = (3+x) = (3+4.64) = 7.64 m
The perimeter of rectangle is :
P = 2(l+b)
P = 2(4.64 m+7.64 m)
P = 24.56 m
or
P = 25 m
Hence, 25 m of canvas will he have to buy to make the enclosure.
Answer:
50 feet
Step-by-step explanation:
According to the Pythagorean theorem a^2+b^2=c^2 and if you put it into this equation it is 30^2 + 40^2 =50^2 which does work out
One theme of the poem Dream variations is the desire to live freely and expressively (option A).
In poems and other literary texts, themes are deep ideas about life that are indirectly expressed by the author. In the case of the poem "Dream variations", the author Langhtons Hughes refers to life and death.

Answer:
The graph of h(x) is shown below.
Step-by-step explanation:
The given function is
The general form of sine function is
Where, a is amplitude, b is period, c is phase shift and d is vertical shift.
So, the amplitude of the given function is 7, period is 1, phase shift is 0 and vertical shift is 0.
It means the minimum value of function is -7 and maximum value is 7.
Therefore the points on the function are (0,0), .
The graph of function is shown below.
Simply follow the units into quantities
E/(mT) = c
Where
E = energy
m = mass
T = temperature
c = specific heat
Solving for T
358/(15*T) = 0.385
T = 62°C
