1 answer:

Karolina [17]2 years ago

7 0

Answer:

How do we calculate the area of this quadrilateral using the coordinates of the four vertices? The answer is simple. We divide the quadrilateral in two triangles (using either of the diagonals), calculate the (positive value of) the areas of each triangle, and add these values to obtain the total area.

Simplify 5 to the negative 4th power over 5 to the 3rd

Licemer1 [7]

"<span>5 to the negative 4th power over 5 to the 3rd</span>" translates to

5⁻⁴ / 5³

So you can just combine exponents.

5⁻⁴ / 5³ = 5⁻⁴ ⁻ ³ = 5⁻⁷ = 1/5⁷

Final answer: 1/5⁷

Use graphing to find the solution of the system of equations. -x^2+y=1, -x+y=2

vladimir2022 [97]

ANSWER

$x=-0.62$ or $x=1.62$

EXPLANATION

For $-x^2+y=1$

We make y the subject to obtain,

$y=x^2+1$

We can easily graph this function, because we just have to transform the graph of $y=x^2$ by shifting the intercept up to $1$ .

As for the straight line, $-x+y=2$ ,

We find the intercepts as follows,

When $y=0,x=-2$ .

When $x=0,y=2$ .

We plot the points $(-2,0)$ and

$(0,2)$ .

We now draw the two graphs on the same graph sheet. The intersection of the two graphs gives the solution to be

$x=-0.62$ or $x=1.62$
