Answer:
Step-by-step explanation:
The trigonometric equations associated with the figure are, respectively:
The components with the unknown angle are cleared and used in the fundamental trigonometric relation:
The following second-order polynomial is presented below:
Roots of the polynomial are described hereafter:
and 
Only the first root is reasonable, as length is a positive variable. The length is .
Answer:
There is NO solution
Step-by-step explanation:
Considering 'y' be the number
Considering x be the smaller number
As 'y' is equal to twice a smaller number plus 3.
so
also
y is equal to twice the sum of the smaller number and 1.
so
so the system of equations become
solving
Therefore, there is NO solution.
Answer:
True, false, true, true.
Step-by-step explanation:
The roots zeros of a quadratic function are the same as the factors of the quadratic function. This is true because your roots are your factors—>(x-3) is a factor, x=3 is the root.
The roots zeros are the spots where the quadratic function intersects with the y-axis. No! Those are called y-intercepts!
The roots zeros are the spots where the quadratic function intersects with the x-axis. True. X-intercepts are your solutions. (x-3) graphed would the (3,0). That’s a solution.
There are not always two roots/zeros of a quadratic function, True. No solution would be when your quadratic doesn’t intersect the x-axis. One solution would be when your vertex would be on the x-axis. Two solutions is when your quadratic intersects the x-axis twice. Can there be infinite solutions? No. It’s either 0, 1, or 2 solutions.
