Answer:
103.5
Step-by-step explanation:
13 + (43 ÷ 2) × 5 - 17
13 + 21.5 × 5 - 17
13 + 107.5 - 17
107.5 - 4
103.5
The relationship between the trigonometric ratios are cos(X) = cos(A), cos(Y) = cos(C) and cos(Z) = cos(B)
<h3>The relationship between the trigonometric ratios</h3>
The given parameters are:
- Scale factor of dilation, k = 2
- cos(X) = 2.5/5/59
Since the transformation is a dilation, it means that both triangles are similar.
So, we have:
cos(X) = cos(A), cos(Y) = cos(C) and cos(Z) = cos(B)
<h3>The segments AC and AB. </h3>
In (a), we have:
Both triangles are similar.
This means that the corresponding points are:
X and A
Y and C
Z and B
So, we have:
AC = 2 * XY
AB = 2 * XZ

Average = sum of all numbers divided by how many numbers there are. so you do 1+0+1+5+6+3+4/7. this gives you 20/7, which is about 2.857
Answer:
All are rational except 2.36473....
Step-by-step explanation:
Any integers are rational, which means the top option (1000892) is rational.
Anything that can be written as a fraction is also rational, so 
is rational.
0.89 can also be written as a fraction as 
and 0.37373737... as 
Therefore the only number that is not rational is the last, as it never repeats itself so can't be written as a fraction.
Hope this helps! Let me know if you have any questions :)
