Question 1 (1 point)

Naily [24]

Answer:

P ( -1, -3)

Step-by-step explanation:

Given ratio is AP : PB = 3 : 2 = m : n and points A(5,6) B(-5,-9)

We will calculate coordinates of the point P which divides line segment AB in the following way:

xp = (n · xa + m · xb) / (m+n) = (2 · 5 + 3 · (-5)) / (3+2) = (10-15) / 5 = -5/5 = -1

xp = -1

yp = (n · ya + m · yb) / (m+n) = (2 · 6 + 3 · (-9)) / (3+2) = (12-27) / 5 = -15/5 = -3

yp = -3

Point P( -1, -3)

If f(3) = 3^x and g(x) = 7^x then the graph of g(x) will be — the graph of f(x) when x<0.

Allushta [10]

Using the given exponential functions, it is found that the graph of g(x) will be less than than the graph of f(x) when x < 0.

<h3>What are the exponential functions?</h3>

The given exponential functions, f(x) and g(x), are respectively given by:

$f(x) = 3^x$

$g(x) = 7^x$

When x < 0, one possible value is x = -1, hence evaluating the functions at these values:

$f(-1) = 3^{-1} = \frac{1}{3}$

$g(-1) = 7^{-1} = \frac{1}{7}$

$\frac{1}{3} > \frac{1}{7}$ , hence, the graph of g(x) will be less than than the graph of f(x) when x < 0.
