Answers

Answer 1

Answer:

1) Between 0 and 1 minute the rate of change is 25 ft./min

2) Between 1 and 2 minute the rate of change is 0 ft./min

3) Between 2 and 4 minute the rate of change is -12.5 ft./min

Step-by-step explanation:

1) Between 0, and 1 feet, we have;

The rate of change = (Final height - Initial height)/(Final time - Initial time)

The rate of change = (40 - 15)/(1 - 0) = 25 ft/min

Between 0 and 1 minute the rate of change = 25 ft./min

2) Between 1, and 2 feet, we have;

The rate of change = (40 - 40)/(2 - 1) = 0 ft/min

Between 1 and 2 minute the rate of change = 0 ft./min

3) Between 2, and 4 feet, we have;

The rate of change = (15 - 40)/(4 - 2) = -12.5 ft/min

Between 2 and 4 minute the rate of change = -12.5 ft./min

(-4, -7) and (-6, 9) in slope-intercept form. Show work

Answers

Answer:

Equation of line in slope-intercept form is: y = -8x-39

Step-by-step explanation:

Given points are:

(-4, -7) and (-6, 9)

The slope-intercept form is given by the equation

[tex]y = mx+b[/tex]

Here m is the slope of the line and b is the y-intercept.

m is found using the formula

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

Here

(x1,y1) = (-4-7)

(x2,y2) = (-6,9)

Putting the values in the formula

[tex]m = \frac{9+7}{-6+4} = \frac{16}{-2} = -8[/tex]

Putting slope in general equation

[tex]y = -8x+b[/tex]

Putting (-6,9) in the equation

[tex]9 = -8(-6)+b\\9 = 48+b\\b = 9-48\\b = -39[/tex]

Putting the value of b we get

[tex]y = -8x-39[/tex]

Hence,

Equation of line in slope-intercept form is: y = -8x-39

The angles of a triangle are in an extended ratio of 5:7:3. What is the measure of the
largest angle?

Answers

Answer:

84°

Step-by-step explanation:

Let the measures of the triangle be 5x, 7x, 3x.

By interior angle sum postulate of a triangle.

5x + 7x + 3x = 180°

15x = 180°

x = 180°/15

x = 12°

7x = 7*12°= 84°

Measure of the largest angle = 84°

Vertical Line Test - Tells us if a graph is a functionVertical Lines - slopes are undefined

Step-by-step explanation:

If the slope m was equal to 0, then it would be a horizontal line rather than a vertical line.

Using the Vertical Line Test, we also know that the graph is not a function.

Usually a vertical line has an undefined slope, as x equals a certain number, and m = unknown.

Answer: It's undefined, because it's vertical
