The x axis is labeled as Number of days.

<h3 /><h3>What is graph?</h3>

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

let x be the number of days and y be money.

So, the equation is

y = -7x + 150.

Hence, the x axis is labeled as Number of days.

Identify the initial amount a and the growth factor b in the exponential function.

alina1380 [7]

Given the equation A (x) = 30 x 8.3 ^x, we can get the initial amount of A when x is equal to zero. Therefore:

A (0) = 30 * 8.3^0

A (0) = 30

In this case the equation grows by 8.3 times as x increases. Therefore the growth factor is 8.3.

Answers:

initial amount = 30

growth factor = 8.3

The answers are not in the given choices. I believe you are giving the wrong equation. If the correct equation here is:

A (x) = 680 x 4.3 ^x

Then the answers are:

initial amount = 680

growth factor = 4.3

The answers are now in the choices given.

Given the points A(-3, -2) and B(6, 1), determine the coordinates of point P on directed line segment that partitions in the rat

serg [7]

Answer:

$P = (3,0)$

Step-by-step explanation:

Given

$A = (-3,-2)$ ---- $(x_1,y_1)$

$B = (6,1)$ --- $(x_2,y_2)$

$m:n =2:1$

Required

The coordinates of P

This is calculated as:

$P = (\frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n}]$

So:

$P = (\frac{2*6+1*-3}{2+1},\frac{2*1+1*-2}{2+1})$

$P = (\frac{9}{3},\frac{0}{3})$

$P = (3,0)$

Question 9 of 10 What is the equation of the following line? Be sure to scroll down first to see all answer options. 10 110 (0,0

Papessa [141]

Answer:

C) $y=-\frac{1}{5}x$

Step-by-step explanation:

The equation of a straight line is given by:

y = mx + b

where m is the slope of the line, b is the y intercept (value of x when y is 0) and y, x are variables.

The equation of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by:

$y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)$

From the graph, the line passes through (0, 0) and (10, -2), hence the equation of the line is:

$y-0=\frac{-2-0}{10-0}(x-0)\\\\y=-\frac{1}{5}x \\\\$

A bird drops a stick from the top of Miami Tower. The height of the stick after x seconds is given by f(x) = 625 - 16x^2.

Leni [432]

ANSWER

The maximum value is 625

EXPLANATION

The height of the stick that the bird dropped is modeled by the function;

$f(x) = 625 - 16x^2$

This function is already in the vertex form.

Let me rewrite it clearly for you to see.

$f(x) = - 16(x - 0)^2 + 625$

When we compare this to;

$f(x)=a(x-h)^2+k$

we have h=0 and k=625.

k=625 is the y-value of the vertex.

This is the maximum value on the graph of this function.
