Step-by-step explanation:
Answer:
(-1,-0.5)
Step-by-step explanation:
We can see from our given graph that Fernando is at point (-4,-2) and Maria is at point (4,2). They will meet at the fountain located somewhere between them.
We can see that fountain will divide our given line segment internally, so we will use section formula, when a point internally divides a segment in ratio m:n.
![[\frac{m*x_2+n*x_1}{m+n},\frac{m*y_2+n*y_1}{m+n}]](https://tex.z-dn.net/?f=%5B%5Cfrac%7Bm%2Ax_2%2Bn%2Ax_1%7D%7Bm%2Bn%7D%2C%5Cfrac%7Bm%2Ay_2%2Bn%2Ay_1%7D%7Bm%2Bn%7D%5D)
Let location of Maria be point
and location of Fernando be
.
Upon substituting m=3 and n=5 in section formula we will get,
Therefore, the fountain is located at point (-1,-0.5).
First, we know the area of a square is side length side length = Area. For this square, the area would be:
18*18=A
324 = A
Now that we know the area that is being referened, we can look at the formula for the area of a rectangle, which is width * length = Area. We know the length and we know the area, so we can fill in these known values and solve for the unknown width.
w*l = A
w*6=324
w=324/6
w=54
So our rectangle has the width of 54 and the length of 6. Lastly, the formula for perimeter is 2w + 2l = P. We can again fill in our knowns and solve for the unknown.
2(54) + 2(6) = P
108 + 12 = P
120 = P
The perimeter of the rectangle is 120 cm.
Answer:

Step-by-step explanation:
The Two triangles are Similar, so using the property of the similar triangles.

On cross multiplication of the fraction:


Dividing by '10' both the sides:


So, the side(m) of the small triangle is '6'
57.3333 the three is infinite
