7 0
1 rational solution

4x² + 12x + 9 = 0
(2x+3)²=0
2x + 3 =0
2x +3 -3 = 0-3
2x = -3
2x/x = -3/2
x = -3/2

~~~~~~~~~~~~~~~~~~~~~~~~~~

Product Property: <span>Sometimes also referred to as the <em>Zero Product Property</em>, states that if AB=0 , than A=0 and/or B=0.</span>

Example: If AB=0, than A=0 and/or B=0.


Quotient Property: <span>Sometimes also referred to as the Quotient <em>of Powers Property</em>, states that when you have the same base, you subtract the exponents.</span>

Example: (5^3)/(5^7) = 5^-4 OR 1/(5^4)


Negative Exponent: <span>This simply means "<em>How many times I you divide by that number?</em>"</span>

Example: 5^-3 = 5/5/5 = 0.2


Power of a Power Property: <span>Sometimes also referred to as the <em>Product of Powers Property</em>, states that rather than adding the exponents of that base, you multiply them instead.  This is the way to find the single exponent of the base.</span>

Example: 5^3^3 = 5^(3*3*3) = 5^27


Power of a Product Property: For this property, rather than multiplying the exponents of the same base, you add them instead.

Example: 5^3 * 5^15 = 25^18

A builder buys 24.5 acres of land to develop a new community of homes and parks. The builder plans to use 0.25 of the land for a
const2013 [10]
0.25 is the same as 1/4 so we have to find what is 1/4 of 24.5. To find this we need to divide 24.5 by 4. 24.5 ÷ 4 = 6.125
The final answer is: The builder will use 6.125 acres for the park.

Can someone help me with this math hw ​
AveGali [126]

Answer:

Step-by-step explanation:

F(x) = x² - 2x + 1

      = (x - 1)²

By comparing this equation with the vertex form of the quadratic equation,

y = (x - h)² + k

Here, (h, k) is the vertex

Vertex of the parabola → (1, 0)

x-intercepts → (x - 1)² = 0

                       x = 1

y-intercepts → y = (0 - 1)²

                       y = 1

Now we can draw the graph of the given function,

From this graph,

As x → 0,

\lim_{x \to 0^{-}} (x-1)^2=1

\lim_{x \to 0^{+}} (x-1)^2=1

f(0) = (0 - 1)²

     = 1

Since, \lim_{x \to 0^{-}} (x-1)^2=\lim_{x \to 0^{+}} (x-1)^2=1

Therefore, given function is continuous at x = 0.
