Answer:
6
Step-by-step explanation:
600 divided by 100= 6
ANSWER:D
Explained:
When in form y=mx+c , the c is the y intercept
Y^2=-x^2 +64
Y=-x + 8
For circle to cut x axis y must = 0
So Y=-x+8 becomes...
0=-x+8 |minus 8 from both sides
-8=-x
So x=8
Y=4x+5.
4 is the gradient
+5 is the y intercept
Answer:
The answer is 235.6

Step-by-step explanation:
The question has missing details, as the scale factor is not given. However, I will give a general explanation on how to calculate the area and perimeter of a dilated shape (triangle).
The following assumptions, apply:
(1) Scale factor of 1/2 from the blue to the yellow triangle.
(2) The dimension of the blue triangle are:



First, calculate the dimensions of the yellow triangle.
The dimension will be the product of the scale factor and the dimensions of the blue triangle.
So, we have:



The perimeter of the blue triangle is:


The perimeter of the yellow triangle is:


Factorize
![P_2 = \frac{1}{2}[x + y + z]](https://tex.z-dn.net/?f=P_2%20%3D%20%5Cfrac%7B1%7D%7B2%7D%5Bx%20%2B%20y%20%2B%20z%5D)
Recall that: 
So:

<em>This implies that the perimeter of the yellow triangle is a product of the scale factor and the perimeter of the blue triangle.</em>
<em></em>
The area of the blue triangle is:



The area of the yellow triangle is:


Rewrite as:
![A_2 = \frac{1}{2}* \frac{1}{2} [\frac{1}{2}x h]](https://tex.z-dn.net/?f=A_2%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2A%20%5Cfrac%7B1%7D%7B2%7D%20%5B%5Cfrac%7B1%7D%7B2%7Dx%20h%5D)
![A_2 = (\frac{1}{2})^2 *[\frac{1}{2}x h]](https://tex.z-dn.net/?f=A_2%20%3D%20%28%5Cfrac%7B1%7D%7B2%7D%29%5E2%20%2A%5B%5Cfrac%7B1%7D%7B2%7Dx%20h%5D)
Recall that:
So:

<em>This implies that the area of the yellow triangle is a product of the square of the scale factor and the area of the blue triangle.</em>
