Hi , the answer is -1 , because -1 is the number that is closest to zero.
First u divide 39.39 to 3 and u get 13.13 so it is already rounded u dont need to round<span />

pythagorean theorem says legs a and b and hypotenuse c of a right triangle are related via the equation c²=a²+b². in other words, adding the sum of the squares of the legs get you the square of the hypotenuse
if the hypotenuse is 4 meters long, c = 4.
if one leg is 3 meters long, we can choose either a or b to be 3. it does not really matter. let us choose a = 3. now we have to find b.
if we have c²=a²+b², we can solve for b.
subtract a² both sides to get c²-a²=b², and then square root both sides to get
b = √(c²-a²)
plugging in our info we get
b = √(4²-3²) = √(16 -9) = √7
so the answer is √7 meters for 22

two triangles are similar, then the proportion of their sides are the same. the propotion between the smaller triangles' hypotenuse and 2cm leg is 5cm/3cm.
notice how the bigger triangle just have a doubled hypotenuse. therefore, the bigger triangle's x and y are just the corresponding smaller triangle values doubled.
x = 6 and y = 8
According to the graph, the value of the constant in the equation below is 80 and is denoted as option D.
What is a Graph?
This is defined as a pictorial representation of data or variables in an organized manner.
From the equation: Height = constant/width
We can pick any point(4,20) on the graph.
20 = c/ 4
c = 20 × 4 = 80
