10 degrees is in a 90 degree angle
90-10 =80
use sin
sin(80)=9/x
get x alone
x=9/sin(80)
Answer: 113.1
Step-by-step explanation: v=4/3(pie)r^3=4/3•(pie)•3^3= 113.09734
The correct answer for this question is "The discriminant is equal to −16, which means the equation has no real number solutions."
<span> −1 = 5x2 −2x
</span><span>5x2 −2x + 1 = 0
</span>
To get the discriminant value, use this formula
= b^2 - 4ac
= (-2)^2 - 4(5)(1)
= 4 - 20
= -16
