(Make sure you are in degrees instead of radians.)
We are given opposite and hypotenuse.
Use Soh-Cah-Toa:
In degrees, this is about 35.9°
y = (9 / (x^2)) + 2
Rewrite in terms of f(x):
y = (9/(g(x))) + 2
To get
g(x) = x^2
f(x) = 9/x + 2
Answer:
Let the test scores be x1, x2, x3, x4
(x1 + x2 + x3)/3 = 88
x1 + x2 + x3 = 264
(x1 + x2 + x3 + x4)/4 = 90
264 + x4 = 360
x4 = 360-264
x4 = 96
Therefore he should get 96 marks in his 4th test to raise his mean test score to 90
The mean score is the total of all scores divided by the total no. Of tests

it's difficult
Step-by-step explanation:
i hope if i know it
The 2 smallest lengths in a triangle have to add up to be greater that the longest side of the triangle. In this case, the longest side is 20. The 2 smallest sides are 5 and 10. 5+10=15, but 15<20. This is why these 3 lengths can’t create a triangle.
