A quantity with an initial value of 4000 grows exponentially at a rate of 0.05% every 5 decades. What is the value of the quanti
icang [17]

The value of the quantity after 1 year, to the nearest hundredth is 4000.00

<h3>The exponential form of an equation</h3>

The standard exponential equation is eexpressed as:

P(t)=P_0e^{kt}

Given the following parameters

P_0=4000\\r =0.0005\\t = \frac{1}{50} =0.02 (yearly)

Substitute into the formula to have:

P(t)=4000e^{0.0005(0.02)}\\P(1)=4000e^{0.00001}\\P(1)=4000

Hence the value of the quantity after 1 year, to the nearest hundredth is 4000.00

Short answer
y >-x + 4
y <= 2(x - 1)^2 - 18

Comment

Let's establish what we are talking about. The question says purple and to me purple means the shaded area above the blue and to the upper right of the parabola. 

Not so. It is the wine colored area right above the parabola according to the direction of he inequalities.

Second thing: the question is trying to see if you can read all he information you need from a graph. 

Step One
Find the equation of the line.
We can read 2 points right away the x and y intercepts.
(4,0) is the x intercept
(0,4) is the y intercept

The general equation for the slope intercept equation is
y = mx + b So when x = 0 then b = y
4 = m*0 + b
b = 4

This far we have
y = mx + 4
when x = 4, y = 0
0 = m*4 + 4 Subtract 4 from both sides.
-4 = m*4      Divide by 4
-4/4 = m
m = - 1

Complete equation is y = -1x + 4
The inequality is y > -x + 4            Top answer block.

Step Two

Find the equation for the parabola

You could just read the minimum point which is (1,-18) There is a catch. (Isn't there always?) This may have a constant in front of the (x - a)^2 term. We'll check that out in the next step.

y = (x - 1)^2 - 18 is the basic vertex solution

Step Three
Find the value of a in
y = a(x -  1)^2 - 18
You have to do this because the answer has a space before the brackets. We need another point. The y intercept might work. 

y = a(0 -1)^2 - 18
Use the point (0,-16)
-16 =  a(1) - 18 
-16 = a - 18 Add 18 to both sides.
2 = a

So the equation of the quadratic is
y <= 2(x - 1)^2 - 18 <<<<<< answer second section down on your question sheet.

Triangle RST was transformed using the rule (x, y) → (–x, –y). The vertices of the triangles are shown.
Gnoma [55]

Triangle RST was transformed by using the rule (x,y) → (-x,-y) and the transformation is described by the transformation of 180° rotation about the origin.

Transform the shapes on a coordinate plane by rotating, reflecting, or translating them. Here we have transformed the triangle using the rotation method.

Rotation is the geometric transformation that revolves each point in a shape a predetermined number of degrees around that point. When the number of degrees is positive, the shape spins counterclockwise; when the number of degrees is negative, it rotates clockwise. The following is a broad description of how rotation about the origin can be transformed.

  • (X,Y) to rotate 90° (-y, x)

  • 180° rotation (x, y) (-x,-y)

  • To rotate (x,y) 270° (y, -x)

Here the points change to R'(-1,-1) , S'(-3,-1) and T'(-1,-6).

A 180° rotation about the origin will be the transformation.

The triangles RST and R'S'T' are first plotted on a graph. The graph is provided for your reference below.

The original triangle RST, which was in quadrant 1, has changed to triangle R'S'T', which is in quadrant 3, as shown in the graph. The rotation around the origin is 180° from quadrant 1 to quadrant 3.

<em>Your question was incomplete. Please check below for full content.</em>

Triangle RST was transformed using the rule (x, y) → (–x, –y). The vertices of the triangles are shown.

R (1, 1)

S (3, 1)

T (1, 6) R' (–1, –1)

S' (–3, –1)

T' (–1, –6)

Which describes the transformation?

The transformation was a 90° rotation about origin.

The transformation was a 180° rotation about origin.

The transformation was a 270° rotation about origin.

The transformation was a 360° rotation about origin.
