Me ajudem com a 3º questão

Alisiya [41]

I can't read that language but I'll guess it says write a second degree equation then solve for n when d=10.

$10 = \dfrac{n(n-3)}{2}$

$20 = n^2 - 3n$

$n^2 - 3n - 20 = 0$

Answer: n² - 3n - 20 = 0

That doesn't factor so there is no integer n solution.

That means there are no polygons with 10 diagonals.

$n = \frac 1 2(3 \pm \sqrt{89})$

What is the equation of the exponential graph shown?

Evgesh-ka [11]

Answer:

f(x) = 100*(1/2)ˣ

Step-by-step explanation:

Exponential function is:

f(x) = a*bˣ

Use two points on the graph to determine the value of a and b:

(0, 100), (1, 50)

Find the values of a and b:

f(0) = a*b⁰ = a = 100
f(1) = a*b¹ = ab = 100b = 50 ⇒ b = 50/100 = 1/2

The function is:

f(x) = 100*(1/2)ˣ
