If a vector V is in standard position and the tip of the vector corresponds to the point (a, b), then we can write the vector in

Aliun [14]

Answer:

$V =$

Step-by-step explanation:

Given

$P= (a,b)$ --- Point

Required

Component of V

From the question, we understand that V is in standard position.

This implies that V starts at the origin (0,0) and ends at (a,b)

So, vector V is:

$V =$

This gives:

$V =$

Exponential Graphs. Can anyone help with this please? I don’t understand anything on this topic, so any explanation will help :)

Fed [463]

Answer:

The correct option is;

a > 1

Step-by-step explanation:

An exponential function can be expressed in the following general form;

f(x) = b·aˣ + k

Where;

b = The coefficient term

a = The base

x = The exponent

k = The vertical shift

The characteristic of an exponential function is that it increases if a > 1

From the graph, we have;

As 'x' increases to the right of the graph, f(x) = aˣ increases (upwards), therefore, a > 1

Find an equation for these points (-5,5) (4,2)

user100 [1]

Answer:

$\large\boxed{y=-\dfrac{1}{3}x+\dfrac{10}{3}}$

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have two points (-5, 5) and (4, 2).

substitute:

$m=\dfrac{2-5}{4-(-5)}=\dfrac{-3}{9}=-\dfrac{1}{3}$

Put the value os a slope and coordinates of the point (4, 2) to the equation of a line:

$2=-\dfrac{1}{3}(4)+b$

$2=-\dfrac{4}{3}+b$ add 4/3 to both sides

$2\dfrac{4}{3}=b\to b=3\dfrac{1}{3}\to b=\dfrac{10}{3}$
