Answer:

x^2 - 10x + 21

Step-by-step explanation:

Sum of zeros

= 7 + 3

= 10

Product of zeros

= 7 x 3

= 21

x^2 - ( sum of zeros )x + product of zeros

= x^2 - 10x + 21

The Quadratic polynomial is x^2 - 10x + 21.

if the zeroes of a <u>quadratic polynomial</u> are a and b, then the polynomial can be written as :

\boxed{{x}^{2}  - (a + b)x + ab}

So,

\hookrightarrow \:  {x}^{2}  - (7 + 3)x + (7 \times 3)

\hookrightarrow \:  {x}^{2}  - 10x + 21

As shown in the diagram, a ship sails 16 nautical miles east from a harbor. It then sails 18 nautical miles in the direction of
Tresset [83]

The angle between the legs of length 16 and 18 has measure 90 + 55 = 145 degrees.

Now use the law of cosines: it says d satisfies

d^2=16^2+18^2-2(16)(18)\cos145^\circ

and solving for d gives

d=\sqrt{16^2+18^2-2(16)(18)\cos14^\circ}\implies d\approx32

so the answer is C.

Which linear inequality is represented by the graph?
aalyn [17]

Answer:

y ≤ 1/3 x - 1.3.

Step-by-step explanation:

First find the equation of the line:

The slope = (-0.3 - (-1.3) / (3 - 0).

= 1/3 so the equation is y = 1/3x + b where b is a constant.

b is the y-intercept which is the value of y when x  = 0 . We see that it is -1.3 ( from the point 0, -1.3).

Since the line is continuous and the shading is below this line the inequality sign is 'less than or equal to',  ≤.
