Answer:

a=\$400,000

Step-by-step explanation:

We have been given that a $400,000 house increases its value at 2.25% each year. We are asked to find the value of a for our function.

We know that exponential growth function is in form y=a\cdot b^x, where,

a = Initial value,

b = For growth b is in for (1+r), where r represents growth rate in decimal form.

2.25\%=\frac{2.25}{100}=0.0225

Upon substituting our given values, we will get:

y=\$400,000\cdot (1+0.0225)^x

y=\$400,000\cdot (1.0225)^x

Therefore, the value of a is $400,000 for our given function.

An exponential equation is represented through the equation; 

y=abˣ

Here, a represents the starting value/point and 
b represents the number by which the equation exponentially increases/decreases by. 

In the given situation, a would be represented by the number $400,000.

Hope I helped :)

Triangle DEF has vertices D(−4, 1), E(2, 3), and F(2, 1) and is dilated by a factor of 3 using the point (1, 1) as the point of
CaHeK987 [17]

Answer: D'(-14,1);\ E'(4,7);\ F'(4,1)

Step-by-step explanation:

Since the center of dilation is not at the origin, we can use the following formula in order to find the coordinates of the vertices of the triangle D'E'F':

D_{O,k}(x,y)=(k(x-a)+a, k(y-b)+b)

Where "O" is the center of dilation at (a,b) and "k" is the scale factor.

In this case you can identify that:

(a,b)=(1,1)\\k=3

Therefore, susbtituting values into the formula shown above, you get that the coordinates ot the resulting triangle D'E'F, are the following:

Vertex D' → (3(-4-1)+1,\ 3(1-1)+1)=(-14,1)

Vertex E' → (3(2-1)+1,\ 3(3-1)+1)=(4,7)

Vertex F' → (3(2-1)+1,\ 3(1-1)+1)=(4,1)
