The graph of a proportional relationship passes through the points (15,3) and (5,y). Find y.
snow_tiger [21]
Y is equal to 1 because to change 15 into 5 you have to divide by 3. 15/3=5. So you do the same to the other coordinate. Divide 3 by 3 to get 1.

Write a polynomial function of least degree with integral coefficients that has the given zeros. ​
Triss [41]

Answer:

Step-by-step explanation:

To get the equation, you must create the factors containing the roots.

So for example the first set of roots can be produced from

(x -2)(x^2 + 9)

which equals (when expanded) x^3 + 9x - 2x^2 - 18 which when put in the correct order gives

x^3 -2x^2 + 9x - 18

The second one is a bit more difficult to judge.

-5  and -3+  square root(2)

I don't think this is a polynomial. The coefficent is not integral. (-3 +√2)

Find the x value of x. If necessary round to the nearest tenth. A=49sq.in.
Sophie [7]

Answer:

Step-by-step explanation:

Alright, lets get started.

Area is given as 49 square inches.

The formula for area A =  

base is given as x

Height is given as x

Hence area is A

A =  

Multiplying 2 in both sides

Taking square root on both sides

hence the answer is x = 9.9 in   :  Answer

Hope it will help :)
