-9xy squared this is the answer
Answer:
1.6
Step-by-step explanation
You can use the angles given to figure out the degree of the angles given and then with that you set up your equation as v divided by Sin(16) is equal to 5.8 divided by sin(87) and cross multiply.
After you cross multiply you should get approximately 1.5987 is equal to v times sin(87)
you then fin out the approximation of sin(87) which should be around 0.9986 and divide both sides by 0.9986 so v is alone and your answer comes out to be v = 1.6
Given:
The function, f(x) = -2x^2 + x + 5
Quadratic equation: 0 = -2x^2 + x +5
where a = -2
b = 1
c = 5
The discriminate b^2 - 4ac = 41
To solve for the zeros of the quadratic function, use this formula:
x = ( -b +-√ (b^2 - 4ac) ) / 2a
x = ( 1 + √41 ) / 4 or 1.85
x = ( 1 - √41 ) / 4 or -1.35
Therefore, the zeros of the quadratic equation are 1.85 and -1.35.
