Answer:
2/65 = 4 teachers for 130
3/100 = 9 teachers for 300
2/55 = 8 teachers for 220
3/85 = 6 teachers for 170
Step-by-step explanation:
f(x)=−7x 2 +8x+2f, left parenthesis, x, right parenthesis, equals, minus, 7, x, squared, plus, 8, x, plus, 2 What is the value o

The discriminant of the function is 120, and the function has 2 different x-intercepts
<h3>How to determine the discriminant?</h3>
The function is given as:
f(x) = -7x^2 + 8x + 2
The discriminant (d) is calculated using:
D =b^2 - 4ac
So, we have:
D = 8^2 - 4 * (-7) * 2
Evaluate
D = 120
Because the value of D is greater than 0, then the function has 2 different x-intercepts

A^2 + b^2 = c^2
the sides are 11, 13, and 25
11^2+13^2=290
25^2 = 625
11^2+13^2<25^2
So, this is an obtuse triangle
