The function f ( x ) = 2 ⋅ 5 ^x can be used to represent an exponential growth curve. Which of the following points is NOT on the curve?

Group of answer choices

(3, 250)

(1, 10)

(2, 20)

(2, 50)

Point (2, 20) does not lie on the given curve.

Step-by-step explanation:

Let us see explanation:

(2, 20) is not on the curve.

Step-by-step explanation:

When x = 3,  f(x) =  2*5^3 = 250 .  So (3, 250) is on the curve.

When x = 1, f(x) = 2*5^1 = 10 .  So (1, 10) is on the curve.

When x = 2, f(x) =  2*5^2 = 50 .   So (2, 50) is on the curve.

From the last line we see that (2, 20) is NOT  on the curve.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
