the question is on the sheet .The shaded region is the area within the figure but not the corner squares

quester [9]

Based on the information given in the exercise, you know that the shaded region has this area:

$6x^2-2xy+3y^2$

And the area of each square region in the corners is:

$4x^2$

Since there are four square regions, you can multiply that the area of any of them by 4, in order to find the total area of them:

$4(4x^2)=16x^2$

Then, in order to find the total area of the figure, you must add the area of the shaded region and the total area of the square regions:

$(6x^2-2xy+3y^2)+(16x^2)=22x^2^{}-2xy+3y^2$

Therefore, the total of the figure is:

$22x^2-2xy+3y^2$

What is the y-intercept of the function f(x) = -3x Ο Ο on who wire on Ο Ο

morpeh [17]

Answer:

see the explanation

Step-by-step explanation:

we know that

The y-intercept is the value of the function when the value of x is equal to zero. Also is called the initial value of the function

I will analyze two cases

Part 1) we have

$f(x)=-3x$

For x=0

substitute

$f(0)=-3(0)=0$

therefore

The y-intercept is the point (0,0)

Part 2) we have

$f(x)=-3^x$

For x=0

substitute

$f(0)=-3^0=-1$

therefore

The y-intercept is the point (0,-1)

Given that f(x) = x^3 + 2x^2 + 1, g(x) = −x^3 −x^2 −4x+ 4, h(x) = f(x) +g(x), and h(x) = 1, what is the value of x?

Studentka2010 [4]

Answer:

x = 2

Step-by-step explanation:

h(x) = f(x) + g(x) = x³ + 2x² + 1 - x³ - x² - 4x + 4 ← collect like terms, thus

h(x) = f(x) + g(x) = x² - 4x + 5

Given

h(x) = 1, then

x² - 4x + 5 = 1 ( subtract 1 from both sides )

x² - 4x + 4 = 0 ← in standard form

(x - 2)² = 0 ← in factored form ( perfect square ), thus

x - 2 = 0 ⇒ x = 2
