Find the gradient of the line segment between the points (-4,2) and (4,5).
Give your answer in its simplest form.

Answers

Answer 1

Answer:

slope= (5-2)/ 4--4

= 3/8

y=3/8x+c

5=3/8(4)+c

5=3/2+c

5-3/2=c

3.5=c

y= 3/8x +3.5

Step-by-step explanation:

Answer 2

The gradient of the line segment between the points (-4, 2) and (4, 5) is 3/8.

What is Gradient of a Line?

Gradient of a line is actually the slope of the line.

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

Slope can also be defined as the tangent of the angle that the line is making with the positive X axis.

Gradient of a line when two points (x, y) and (x', y') are given is,

Gradient, m = (y' - y) / (x' - x)

Here, given are two points (-4, 2) and (4, 5).

x = -4, y = 2, x' = 4 and y' = 5

Gradient = (5 - 2) / (4 - -4) = 3/8

Hence the gradient of the line segment between the given points is 3/8.

Answer:

8 = 4.5

10 = 3.6

12 = 3

14 = 2.57 (2.6 simplified)

Step-by-step explanation:

You can solve this by dividing 36 (the whole amount of meter of fences)

by each number of the length

area                    width

36 divided by 2 = 18

36 divided by 4 = 9

36 divided by 6 = 6

36 divided by 8 = 4.5

36 divided by 10 = 3.6

36 divided by 12 = 3

36 divided by 14 = 2.57 (2.6 simplified)

36 divided by 16 = 2.25 (2.3 simplified)

Find p(–4) if p(x) = 3x^3 – 2x^2 + 6x – 4



If r(x) = x^3 – 2x + 1, find r(2a^3).

Answers

Answer:

I think that the first part would be -252, but I'm not sure about the second part

Step-by-step explanation:


Find p(–4) if p(x) = 3x^3 – 2x^2 + 6x – 4

p(-4) = 3x^3 – 2x^2 + 6x – 4

p(-4) = 3(-4)^3 – 2(-4)^2 + 6(-4) – 4
= 3(-64) - 2(16) + 6(-4) - 4
= -192 - 32 - 24 - 4
p(-4) = -252


r(x) = x^3 – 2x + 1, find r(2a^3)

r(x) = (x^3 – 2x + 1) (2a^3)
= (2a^3) x^3 + (2a^3) (-2x) + (2a^3) * 1
= x^3 (2a^3) - 2x (2a^3) + 1 * (2a^3)
r(x) = 2a^3x^3 - 4a^3x + 2a^3
