Answer:
C.
Step-by-step explanation:
the given graph touches the Y-axis in the point (5;0), it means the only zero.
To the additional: the graph is y=(x-5)².
Answer:
x = 1.5
Step-by-step explanation:
using the sine ratio in the right triangle and the exact value
sin60° = , then
sin60° = = = ( cross- multiply )
2x = 3 ( divide both sides by 2 )
x = 1.5
So discriminant gives us 3 possibilites connected with result of the equation b^2-4ac. If it is bigger than zero, there are 2 solutions, if answer is exactly 0, then there is one answer and if the number is lower than 0, there are no solutions.
Discriminant of your quadratic equation is (-4)^2-4*1*5=16-20=-4, so there are no solutions.
2t^2+1
Subtract t^2 from 3t^2 you get 2t^2
which is 2t^2+1 answer
Answer:
(-4,-3)
Step-by-step explanation:
The x value is -4 and the y value is -3
