Answer:
x = 18; y = 20
Step-by-step explanation:
6.
Triangles KLM and KNO are similar, so the ratios of the lengths of corresponding sides are equal.
KL/KN = LM/NO
10/30 = 6/x
Cross multiply.
10x = 6 * 30
10x = 180
x = 18
KL + LN = KN
10 + y = 30
y = 20

Answer:
47 degrees
Step-by-step explanation:
Add all the numbers we know
the line is 180

Answer:
480m
Step-by-step explanation:
First we have to find the perimeter of the field.
We know that the area is 144m and that the field is a square.
Since a squares sides are all equal, we can do
, which is 12m.
So, one side of the field is 12m; now we just find the perimeter which is easy since its a square. 12*4=48m
If Andrea walked around it 10 times, then we just multiply the perimeter by 10
48*10=480m
Using an exponential function, it is found that the value of the function when x = 4 is of f(4) = 15.95.
<h3>What is an exponential function?</h3>
It is modeled by:

In which:
- b is the rate of change, as a decimal.
In this problem, we have that f(-1)=5, hence:


a = 5b
We also have that f(7)=32, hence:

Since a = 5b:

![b = \sqrt[8]{\frac{32}{5}}](https://tex.z-dn.net/?f=b%20%3D%20%5Csqrt%5B8%5D%7B%5Cfrac%7B32%7D%7B5%7D%7D)
b = 1.2612.
a = 5b = 5 x 1.2612 = 6.306.
Hence the function is given by:

Then, when x = 4, we have that:
