You measure your height and the height of your shadow the you measure the height of the poles shadow and you then have the equation
y(your height)/s(your shadows height)=x(flagpoles height)/z(flagpoles shadow)
then to find the answer you just multiply the z by y/s

One of the roots of the equation x^2-13x+q=0 is 12. Find the other root in the value of the coefficient Q.

fenix001 [56]

Considering that 12 is a root of the function, the value of coefficient Q is of 12.

<h3>What does it means that x is a root of a function f(x)?</h3>

It means that f(x) = 0.

In this problem, the function is given by:

f(x) = x² - 13x + q.

Since 12 is a root, we have that f(12) = 0, hence:

12² - 13 x 12 + q = 0

q - 12 = 0.

q = 12.

Solve the following quadratic function by utilizing the square root method. y = 100 – x2

Anna [14]

Answer:

x = ± 10

Step-by-step explanation:

To solve the equation let y = 0 , that is

0 = 100 - x²( add x² to both sides )

x² = 100 (I take the square root of both sides )

x = ± $\sqrt{100}$ = ± 10

Then solution is x = - 10, x = 10
