Answer:
$287.50
Step-by-step explanation:
31.25 x 9.20 = $287.50
Step-by-step explanation:
sin 0 = opposite ÷ hypothenus
sin 0 = 3 / 5
3 / 5 = x / 15
5 × n = 15
n = 3
x = 3 × 3 = 9
y = use pythagoras
= 12
tan 0 = opposite ÷ adjacent
tan 0 = 9/12
"The discriminant is prime?" I haven't heard that one before.
Here are the general rules:
1. a positive discriminant results in two real, unequal roots.
2. a zero discr. results in two real, equal roots.
3. a negative discr. results in two complex roots, which sometimes means two imaginary roots.
Answer:
x = 
Step-by-step explanation:
First, you have to leave 2x by itself on the left side of the equation:
2x = 60/8
Then divide,
x = 15/4
Simplified fraction: x = 
No because 9/1,000 in decimals would be 0.009 because if the number was a 3 number then it would go in the tenths
