Focus at (8,0), directrix x = -8
Answers
The equation of a parabola for the focus at (8,0), directrix x = -8 is found as y² = 32x.
What is meant by the term parabola?A parabola is an open plane symmetrical curve created by the intersection of the a cone and a plane parallel towards its side. A projectile's path under the effect of gravity ideally continues to follow a curve of the this shape.The standard equation of parabola,
(y−n)² = 4p(x−m),
In which,
Vertex is (m,n)Axis of symmetry is y = mFocus is (p+m,n)Directrix is x =m−p.For the given value in question;
p+m = 8
n = 0
m−p = -8
m = 0
p = 8
Put the obtained values in general equation;
y² = 4×8(x+0)
y² = 32x
Thus, the equation of a parabola for the focus at (8,0), directrix x = -8 is found as y² = 32x.

Pls help: find the rational expression state any restrictions on the variable

Simplification of Rational Expressions
Given the rational expression:
[tex]\frac{n^4-10n^2+24}{n^4-9n^2+18}[/tex]Simplify and state the restriction for the variable n.
Let's work on the numerator and denominator independently. Factoring the numerator:
[tex]\begin{gathered} n^4-10n^2+24=n^4-4n^2-6n^2+24 \\ n^4-10n^2+24=n^2(n^2-4)-6(n^2-4) \\ n^4-10n^2+24=(n^2-6)\mleft(n^2-4\mright) \end{gathered}[/tex]The denominator can be factored in a similar way:
[tex]\begin{gathered} n^4-9n^2+18=n^4-3n^2-6n^2+18 \\ n^4-9n^2+18=n^2(n^2-3)-6(n^2-3) \\ n^4-9n^2+18=\mleft(n^2-3\mright)(n^2-6) \end{gathered}[/tex]Thus, rewriting the expression:
[tex]\frac{n^4-10n^2+24}{n^4-9n^2+18}=\frac{(n^2-4)(n^2-6)}{(n^2-3)(n^2-6)}[/tex]Before simplifying, we must state the restrictions for the variable. The denominator cannot be 0, thus:
[tex]\begin{gathered} n^2-3\ne0\Rightarrow n\ne\pm\sqrt[]{3} \\ n^2-6\ne0\Rightarrow n\ne\pm\sqrt[]{6} \end{gathered}[/tex]Now simplify:
[tex]\frac{n^4-10n^2+24}{n^4-9n^2+18}=\frac{(n^2-4)}{(n^2-3)}[/tex]Combining the final expression with the restrictions, we stick with choice a.

5. Given: Line segment AD bisects
Answers
Given information:
AD bisects
We are in a triangle that has been bisected , and therefore, the segment AD cuts the side BC of the triangle in two equal parts.
Also, since AD bisects the angle, <1 equals <2.
Step 1: Angle bisector defines two equal angles, then <1 = <2
They also tell us that angle <3 = <1 (premise)
Then, using transitive property we have:
<1 = <3
and <1 = <2 due to result of a bisection
then using transitive property:
<3 = <1 = <2
<3 = <2
Just lmake sure you use "transitive" property as the reason for the congruency in the last step.

Explanation:
For an investment whose interest is compounded continuously, the amount in the account after t years is determined using the formula:

Substitute the given values into the formula:
[tex]6000=4000e^{0.035t}[/tex]Then solve for t:
[tex]\begin{gathered} \text{ Divide both sides by 4000} \\ \frac{6000}{4000}=\frac{4000e^{0.035t}}{4000} \\ 1.5=e^{0.035t} \\ \text{ Take the ln of both sides:} \\ \ln(1.5)=\ln(e^{0.035t}) \\ 0.035t=\ln(1.5) \\ \text{ Divide both sides by }0.035 \\ \frac{0.035t}{0.035}=\frac{\operatorname{\ln}(1.5)}{0.035} \\ t=11.58 \\ t\approx12\text{ years} \end{gathered}[/tex]It will take Dennis 12 years (rounded to the nearest year) before he has $6,000 in his account.

I need to use the formula for a trapezoid and find the area and perimeter
Answers
Hello there. To solve this question, we'll have to remember some properties about trapezoids and right triangles.
Given the following trapezoid:
We have to determine its area and perimeter.
For this, remember that:
The area of a trapezoid with bases B and b (larger and smaller, respectively) and height h can be found by the formula
[tex]A=\dfrac{(B+b)\cdot h}{2}[/tex]The perimeter is the sum of the measures of all sides of the figure.
For the perimeter, we'll use the pythagorean theorem to determine the measure of the legs of the trapezoid.
Okay. Notice that in the trapezoid, the larger base B measures 41, the smaller base measures 21 and the height is 18.
By the formula for area, we get
[tex]A=\dfrac{(41+21)\cdot18}{2}=62\cdot9=558[/tex]Now, notice we can determine a right triangle on the left:
To determine the legs of the triangle, we make
[tex]\dfrac{41-21}{2}=\dfrac{20}{2}=10[/tex]Now we have a right triangle with legs 10 and 18.
Using the Pythagorean theorem:
[tex]a^2+b^2=c^2[/tex]For a triangle with legs a and b and hypotenuse c, the sum of the squares of the legs is equal to the square of the hypotenuse.
Using a = 10 and b = 18, we get
[tex]\begin{gathered} 10^2+18^2=c^2 \\ 100+324=c^2 \\ 424=c^2 \\ 4\cdot106=c^2 \\ c=2\sqrt{106} \end{gathered}[/tex]Since the other right triangle is the same, the other leg have the same measure, hence we add
[tex]\text{ Perimeter }=21+41+2\cdot2\sqrt{106}=62+4\sqrt{106}[/tex]We can approximate this value using a calculator

Given:
The coordinates of triangle ∆ABC are (1,4), (5,6) and (3,10).
The triangle is reflected across y axis forming ∆A'B'C'.
The objective is to find the vertices of the new triangle.
Explanation:
If a triangle with coordinate (a,b) is reflected across y axis, then the change in reflected coordinate will be (-a,b).
If a triangle with coordinate (a,b) is reflected across x axis, then the change in reflected coordinate will be (a,-b).
To find vertices:
Since, the given triangle is reflected across y axis, then the vertices of new triangle will be,
