Step-by-step explanation:

Given:

Graphs of f(x) and g(x) are given

From the given graphs:

Finding g ( f (-3) ):

-----> g ( f (-3) )

-----> g(5)

-----> -9

so,

Two numbers add to be 5 multiply to be -6

FrozenT [24]

Answer:

-1, 6

Step-by-step explanation:

x + y = 5

xy = -6

Take first equation and rewrite it. y = -x + 5

Then substitute the new equation in the second one.

x(-x + 5) = -6

-x^2 + 5x + 6 = 0

Divide by -1

x^2 - 5x - 6

(x + 1)(x - 6) = 0

x = -1, 6

John wants to nail a thumbtack on his circular board, pictured below. If the thumbtack is equally likely to be placed anywhere o

Nikitich [7]

Answer: A. 51%

Step-by-step explanation:

Area of circle = $\pi r^2$ , where r = radius of the circle.

In the figure below, we have the complete question.

According to that,

Radius of outer circle = 7ft

Radius of inner circle = 5ft

The probability that the thumbtack will be placed on the inner circle

$=\dfrac{\text{Area of inner circle}}{\text{Area of outer circle}}\\\\=\dfrac{\pi (5)^2}{\pi (7)^2}\\\\=\dfrac{25}{49}$ [π is canceled from numerator and denominator

in percent, $\dfrac{25}{49}\times100=51.0204081633\%\approx51\%$

So, the probability that the thumbtack will be placed on the inner circle = 51%

Hence, the correct option is A. 51%.
