A parabola has a vertex at (0,0). The focus of the parabola is located at (4,0). What is the equation of the directrix? x=−4 y=−4 x=4 y=4
The equation of directrix of the parabola will be x = -4.
What is directrix ?Directrix is a straight line distance to which from any point of a conic section is in fixed ratio to the distance from the same point to a focus. The directrix is perpendicular to the axis of symmetry and does not touch the parabola.
We have,
Vertex of parabola = (0, 0),
Focus of the parabola = (4, 0),
Now,
The Equation of directrix is given by y = -a
Where,
The equation of the parabola, [tex]y^2 = 4ax[/tex],
And,
Focus at (a, 0),
i.e. a = 4 (As the given focus is (4, 0))
And,
The axis of the parabola is the positive x − axis.
So,
The equation of the directrix of this parabola,
x + a = 0,
i.e.
x + 4 = 0
⇒
x = -4
Hence, we can say that the equation of directrix of the parabola will be x = -4.

What is the measure of _Y, in degrees?
y
A. 116°
B. 32°
C. 640
D. Cannot be determined
Answer:
C. 116º
Step-by-step explanation:
Both sides are congruent, so the triangle is an isosceles triangle. So angle Z will have to be congruent to angle X. Add together the two angles, (32 + 32) and subtract the sum from 180º since all triangles add up to 180º.
32 + 32 = 64
180 - 64 = 116

which of the following statements is false about the area of a circle
Answer:
Step-by-step explanation:
All are true except for the second. Only the second is false.
(pi)(d) is the circumference (not the area) of a circle.
The incorrect statement is [tex]A = \pi d[/tex].
The correct option is 2.
What is Surface Area?The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface. Square units are used to measure it as well. The region that includes the base(s) and the curved portion is referred to as the total surface area. It is the overall area that the object's surface occupies. The total area of a form with a curved base and surface is equal to the sum of the two areas.
As per the given data:
We have to find out the incorrect statements out of the given options about the area of a circle.
[tex]A = \pi r^2[/tex]
This statement is correct, as the area of a circle is pi times square of the radius.
[tex]A = \pi d[/tex]
This statement is incorrect, as the area of a circle is given by:
[tex]A = \pi r^2 =\frac{ \pi d^2}{4}[/tex]
The area of a circle determines how much space is covered by the circle.
This statement is correct.
The area of a circle describes the number of square units that fit inside the circle.
This statement is correct.
Hence, the incorrect statement is [tex]A = \pi d[/tex].

The sum of 7 and Rita's score is 54
Answer:
the answer to your question is 61
Step-by-step explanation:
54+7=61
Answer:
47
Step-by-step explanation:
54-7=47
I'm assuming we are trying to find Rita's score. We know that the total is 54. "The sum" refers to addition, so we must reverse the problem to find her score
54- 7= 47
Total - 7 = her score
A new savings account is opened with 400 and gains 3% every year.what is the exponential function?
Answer:
Exponential function is:
y = 100 (1.03)ˣ
Step-by-step explanation:
We know that the exponential growth function is of the form
y = a (1 + r)ˣ
Here:
a = initial value
r = growth rate
x = number of time intervals that have passed
Given that A new savings account is opened with 400. Thus,
a = 400
Given that a new saving account gains 3% every year.
r = 3% = 0.03
now substituting a = 400 and r = 0.03 in the function
y = a (1 + r)ˣ
y = 100 (1 + 0.03)ˣ
y = 100 (1.03)ˣ
Therefore, exponential function is:
y = 100 (1.03)ˣ
Please note that the growth factor i.e. 1.03 is greater than 1, so the exponential function represents exponential growth.

The system of linear inequalities of the given points is required.
The system of inequality is
[tex]x-3y\leq -9[/tex]
[tex]3x-y>2[/tex]
Points of the first line
[tex](0,3)[/tex]
[tex](3,4)[/tex]
The equation of the line is
[tex]y-3=\dfrac{4-3}{3-0}(x-0)\\\Rightarrow y-3=\dfrac{1}{3}x\\\Rightarrow y-\dfrac{1}{3}x=3\\\Rightarrow 3y-x=9\\\Rightarrow x-3y=-9[/tex]
Let us take a point above this line [tex](2,4)[/tex]
It is also a solid line.
[tex]2-3\times 4=-10<-9[/tex]
So, the inequality is [tex]x-3y\leq -9[/tex]
Points of the second line
[tex](0,-2)[/tex]
[tex](1,1)[/tex]
The equation of the second line is
[tex]y+2=\dfrac{1+2}{1-0}(x-0)\\\Rightarrow y+2=3x\\\Rightarrow 3x-y=2[/tex]
Let us take a point towards the right of the line [tex](2,2)[/tex]
[tex]3\times 2-2=4>2[/tex]
Since, the line is dashed the second inequality will be [tex]3x-y>2[/tex]

Let f be the function defined by f(x)=x^3+x^2+x. Let g(x)=f^-1(x), where g(3)=1. What is the value of g'(3)?
Answer:
1/6
Step-by-step explanation:
Given the function
f(x)=x^3+x^2+x
Get the inverse. Let y = f(x)
y = x^3+x^2+x
Replace y with x
x = y³+y²+y
Differentiate with respect to x
1 =3y²dy/dx + 2ydy/dx + dy/dx
1 = (3y²+2y+1)dy/dx
dy/dx = 1/3y²+2y+1
g'(x) = 1/3(g(x))²+2g(x)+1
If x = 3
g'(3) = 1/3(g(3))²+2g(3)+1
g'(3) =1/3(1)²+2(1)+1
g'(3) = 1/3+2+1
g'(3) = 1/6
Hence g'(3) = 1/6
