Solve for y2. d = y2- y1

1 answer:

8 0

D=y2-y1
D+y1= y2-y1+y1 add y1 to both sides to cancel it out.

D+y1=y2 that drops -y1 for the right side but the left remains.

And that's your answer.

Answer the question and make sure it is squared and in meters please i need help

Readme [11.4K]

Answer:

10,000 square meters.

Step-by-step explanation:

First, let's split this shape into a rectangle and a triangle to make it easier.

Rectangle:

A = bh

We know the base is 120m and the height is 30m. So simply plug those into the equation.

A = (120)(30) = 3,600 square meters.

Triangle:

A = 1/2bh

Since we split the shape up, we have to calculate the triangles base and height.

To find the base, take the 120 and subtract the 40, giving us 80.

To find the height, take the 190 and subtract the 30, giving us 160.

Now take those numbers and plug them into the equation.

A = 1/2(80)(160) = 1/2(12,800) = 6,400 square meters.

Total:

Simply add the area of the rectangle to the area of the triangle to find the area of the entire shape.

A = 3,600 + 6,400 = 10,000 square meters.

Which graph represents the function f(x)= 0.2^x + 3

Dennis_Churaev [7]

The third graph or bottom left graph represents $f(x) = 0.2^{x} + 3.$

Step-by-step explanation:

Step 1:

To determine which of the given graphs represents the equation $f(x) = 0.2^{x} + 3$ , we substitute some values in the place of x.

When $x=0,$ $f(x) = 0.2^{x} + 3, f(0) = 0.2^{0} + 3= 4.$

Anything with an exponent of 0 will equal 1.

So the graphs on the right side cannot be the answers.

Step 2:

Now we substitute another value to determine which graph represents $f(x) = 0.2^{x} + 3.$

When $x=1,$ $f(x) = 0.2^{x} + 3, f(1) = 0.2^{1} + 3= 4.2.$

The value of f(x) when $x=1$ is lesser than the value of f(x) when $x =0.$

So the third graph or bottom left graph represents $f(x) = 0.2^{x} + 3.$
