The x axis should be time periods and since the range of months is in 3 months, the increments should be every 3 months.

The y-axis should be the sales and since most of the amounts are in 6 digits, we use increments of $100,000.

Therefore, the answer is the 3rd options:
x-axis: time period in increments of 3 months; y-axis: sales in increments of $100,000

WRITE INEQUALITIE TO DESCRIBE A REGION CONSISTING OF ALL POINTS BETWEEN ( BUT NOT ON ) THE SPHERES OF RADIUS R AND r CENTERED AT

Andreas93 [3]

Answer:

$r^2$

Step-by-step explanation:

We are given the following in the question:

$r < R$

where r and r are the radius of the circle.

General equation of circle:

$(x-h)^2 + (y-k)^2 + (z-j)^2 = r^2$

where(h,k,j) is the center of the circle and r is the radius of circle.

If the circle is centered at origin, then,

$x^2 + y^2+z^2 = r^2$

Equation of circle with radius R centered on origin

$x^2 + y^2+z^2 = R^2$

Inequality to describe the region that consist of all points lying between the sphere of radius r and R but not on the sphere is given by:

$r^2$

For the curve with equation y = <img src="https://tex.z-dn.net/?f=x%5E%7B2%7D" id="TexFormula1" title="x^{2}" alt="x^{2}" align=

bixtya [17]

Answer:

Below.

Step-by-step explanation:

a) First we find the derivative of the function, which gives us the gradient in terms of x:-

y = x^2 + 4x + 3

Gradient at x = dy/dx = 2x + 4.

When the curve cuts the x-axis, y = 0:

x^2 + 4x + 3 = 0

(x + 1)(x + 3) = 0

so x = -1 and -3 where the curve cuts the x axis.

The gradients at these point are therefore:

At x = -1 gradient = 2(-1) + 4 = 2

at x = -3 gradient = 2(-3) + 4 = -2.

b) (i) Where the tangent is parallel to x axis the gradient = 0

so 2x + 4 = 0 giving x = -2.

We now need to substitute x = -2 into the original function to find the y coordinate.

So the coordinates are (-2, (-2)^2 + 4(-2) +3))

= (-2, -1)

(ii) First find the slope of the line 6x + 3y = 7:

3y = -6x + 7

y = -2x + 7/3.

So the slope is -2.

Thus -2 = 2x + 4

2x = -6

x = -3

So the coordinates are (-3, (-3)^2 + 4(-3) + 3)

= (-3, 0).
