For a body moving with increasing acceleration, the graph will be in the form of an exponential function. An example of the exponential function is shown in the attached diagram.

Mathematically exponential function can be expressed by the following equation.

F(a) = e^a, where a>0.

Write down the coordinates of the image of the point (2-3) under reflecting about the line joining the points (3, 5) and (3,7)

Murrr4er [49]

Answer:

(4 , -3)

Step-by-step explanation:

the points (3 , 5) and (3 , 7) have the same x-coordinates 3

then ,the line D joining them has the equation

D : x = 3

the image of the point A(2 , -3) under reflecting about The line D ,

lie on the line ∆ perpendicular to D and passes through A.

∆ perpendicular to D then the equation of ∆ is :

∆ : y = a ,where a is a real number.

Calculating ‘a’ :

∆ passes through A

Then

-3 = a

Therefore

the final equation of ∆ is :

∆ : y = -3

Obviously, the lines D and ∆ intersect at the point M(3 , -3)

FINAL STEP :

Calculating the coordinates of the point B(x , y) image of the point A(2 , -3)

M is the midpoint of the line segment AB :

Then

3 = (2 + x)/2 and -3 = (-3 + y)/2

Then

x = 4 and y = -3.

Using the formula A = 6s2, solve when s = 2?

rosijanka [135]

Answer:

When s=2, A=24

Step-by-step explanation:

We are given the formula $A = 6s^2$

We need to solve and find value of A , when s=2

So, putting value of s in the given formula we can find value of A

The formula given is:

$A=6s^2\\Put\:s=2\\A=6(2)^2\\A=6(4)\\A=24$

So, by putting s= 2, We get A=24
