A is the answer cause 5x6 equals 30 and you have to multiple the top by 6 two which will give you 12 (2x6)

Answer:

12 because 12/30 is equal to 40% and 2/5 is is equal to 40% too

First let's calculate the measure of our angle.

360 degrees - 296 degrees = 64 degrees.

Now, we can set the sum of our tiny angles equal to the whole angle.

64 degrees = 29 degrees + (x - 24) degrees.

Combine like terms.

64 degrees = 5 degrees + x

Subtract 5 degrees from both sides.

59 = x

$V_1$ - volume without <span>pots and pans
$V_2$ - volume with </span>pots and pans
$V_2-V_1$ - volume of pots and pans

$V_1=17\cdot23\cdot h=391h\ in^3\\ V_2=391(h+0.6)=391h+234.6\ in^3\\
V_2-V_1=391h+234.6-391h\\
V_2-V_1=234.6 \ in ^3$

Write the equation of the parabola that has its x-intercepts at (1+<img src="https://tex.z-dn.net/?f=%5Csqrt%7B5%7D" id="TexForm

Answer:

$y=2x^2-4x-8$

Step-by-step explanation:

<u>Factored form of a parabola</u>

$y=a(x-p)(x-q)$

where:

p and q are the x-intercepts.
a is some constant.

Given x-intercepts:

(1+√5, 0)
(1-√5, 0)

Therefore:

$\implies y=a(x-(1+\sqrt{5}))(x-(1-\sqrt{5}))$

$\implies y=a(x-1-\sqrt{5})(x-1+\sqrt{5})$

To find a, substitute the given point (4, 8) into the equation and solve for a:

$\implies a(4-1-\sqrt{5})(4-1+\sqrt{5})=8$

$\implies a(3-\sqrt{5})(3+\sqrt{5})=8$

$\implies4a=8$

$\implies a=2$

Therefore, the equation of the parabola in factored form is:

$\implies y=2(x-1-\sqrt{5})(x-1+\sqrt{5})$

Expand so that the equation is in standard form:

$\implies y=2(x^2-x+\sqrt{5}x-x+1-\sqrt{5}-\sqrt{5}x+\sqrt{5}-5)$

$\implies y=2(x^2-x-x+\sqrt{5}x-\sqrt{5}x+\sqrt{5}-\sqrt{5}+1-5)$

$\implies y=2(x^2-2x-4)$

$\implies y=2x^2-4x-8$

Answer:

When N is an even number, use the first equation in the matrix. When N is negative use the second equation.
