The vertex, focus and directrix of the parabola y = x²/4 are:
v = (0,0)f = (4, 0)d = y = -4What is a parabola?The parabola is a geometric shape that is formed from the intersection of a vertical plane in a cone.
The parabola is a quadratic function, it is composed of a vertex, or inflection point, a focus and a directrix.
In this case we have an expression given by:
x = y²/16
We must find the canonical equation:
(y - 0)² = 16 (x - 0)
has the form
(y - k)² = 4p(x - h)
This means that the vertex of this parabola is
v = (h, k)
v = (0,0)
To know the focus we must know the value of "p".
4p = 16p = 4f = (0 + 4, 0)
f = (4, 0)
Directrixd = y = 0 - 4
d = y = -4

In Euclidean geometry, any three points that are not collinear produce a singular triangle angle and a singular plane (i.e. a two-dimensional Euclidean space). In other words, every triangle angle is contained in a plane, and there is only one plane that contains that triangle. All triangles angle are enclosed in a single plane if all of the geometry is the Euclidean plane, however, this is no longer true in higher-dimensional Euclidean spaces.

Solve each system by substitution.
3u + 8 = 4v , 24v = 6 - 3u
By substitution, the solution of the system of equations, 3u + 8 = 4v and 24v = 6 - 3u, is (u , v) = (-2 , 1/2).
A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.
There are three methods that can be used to solve system of linear equations.
1. Elimination
2. Substitution
3. Graphing
Using substitution method, given two linear equations in u and v,
3u + 8 = 4v (equation 1)
24v = 6 - 3u (equation 2)
Using the first equation, find the value of one variable, lets say u, in terms of the other.
3u + 8 = 4v (equation 1)
3u = 4v - 8
u = (4v - 8)/3
Substitute the value of u to the second equation.
24v = 6 - 3u (equation 2)
24v = 6 - 3[(4v - 8)/3]
24v = 6 - (4v - 8)
24v = 6 - 4v + 8
Combining all terms containing the variable v on one side and the constants on the other side of the equality, and solve for v.
24v = 6 - 4v + 8
24v + 4v = 6 + 8
28v = 14
v = 1/2
Substitute the value of v in the equation for u and solve for u.
u = (4v - 8)/3
u = [4(1/2) - 8]/3
u = (2 - 8)/3
u = -6/3
u = -2
Hence, the solution of the given system of equations is (u , v) = (-2 , 1/2).

Write an equation in slope-intercept form for the line described.
passes through (-12,3), perpendicular to y=-2/3x-11
The equation in slope-intercept form for the line that passes through (-12,3), perpendicular to y = -(2/3)x-11 is y = (3/2)x + 21.
The slope intercept form of a line is:-
y = mx + b
Where:-
m represents the slope of a line
b represents the y-intercept of a line
x and y represent the ordered pairs (x,y) throughout a line
We are given the line y = - (2/3)x-11 is perpendicular to the line whose equation we have to find.
Hence,
slope of the line*(-2/3) = -1
slope of the line, m = 3/2
Also, (-12,3) passes through the line,
Hence,
3 = (3/2)*(-12) + b
3 = -18 + b
b = 21
Hence, the equation of the line in slope intercept form is y = (3/2)x + 21.

Can someone explain this to me??
Answer:

Step-by-step explanation:
You want the height drawn on each triangle corresponding to the base shown.
HeightThe height of a triangle is the perpendicular distance from the base to the opposite vertex. The point at which the height segment meets the base may or may not lie on the triangle.
The height segments for the two given triangles are shown in the attachment.
__
Additional comment
As this problem suggests, any side of a triangle may be designated the "base."
The height segment is also called an altitude. When all three altitudes are extended until they coincide, the point at which they meet is called the "orthocenter" of the triangle.
The orthocenter of an acute triangle lies inside the triangle. For a right triangle, it lies at the right-angle vertex. For an obtuse triangle, the orthocenter is outside the triangle.

A rectangular painting measures 13 inches by 20 inches and contains a frame of uniform width around the four edges. The perimeter of the rectangle formed by the painting and its frame is 98 inches. Determine the width of the frame.
The width of the frame is 8 inches.
We are given that:
The measures of the rectangular painting are:
Length = 13 inches
width = 20 inches
Now, the frame is of uniform with around the corner.
Let it be x inches.
So the new dimensions will be:
Length = 13 + x inches
Width = 20 + x inches.
Also, we are given that:
Perimeter = 98 inches
So, we get that:
P = 2(l + b)
Substituting the values, we get that:
98 = 2 (13 + x + 20 + x)
98 = 2( 33 + 2 x)
98 = 66 + 4 x
4 x = 98 - 66
4 x = 32
x = 32 / 4
x = 8 inches.

Abdoulaye is driving on a long road trip. He currently has 11 gallons of gas in his car. Each hour that he drives, his car uses up 1 gallon of gas. How much gas would be in the tank after driving for 3 hours? How much gas would be left after tt hours?
The amount of gas he would have in the tank after 3 hours is 8 gallons.
The gas left after tt hours is 11 - tt.
How much gas would be left in the tank?In order to determine the amount of gas that would be left in the tank, the amount of gas used would have to be subtracted from the initial amount of gas in the car.
Subtraction is the mathematical operation that is used to determine the difference between two or more numbers. The sign that is used to represent subtraction is -.
Amount of gas left = initial amount of gas - (gas used per hour x number of hours travelled)

Find the sum of each series. Σ⁵ n=1 (3 n+1)
The sum of the given series is 50
The summation notation or sigma notation is used to simplify the writing of long summation into a single formula.
The given series in sum notation is:
[tex]\sum\limits^5_{n=1} {(3n+1)}[/tex]
Substitute n = 1 ...5 into the nth term formula inside the sum notation:
a(1) = 3 . (1) + 1 = 4
a(2) = 3. (2) +1 = 7
a(3) = 3. (3) +1 = 10
a(4) = 3. (4) +1 = 13
a(5) = 3. (5) +1 = 16
Hence, the series:
4 + 7 + 10 + 13 + 16
We can evaluate the sum directly by adding all the terms:
S(5) = 4 + 7 + 10 + 13 + 16 = 50
Or we can also use the sum formula of an arithmetic series:
S(n) = n/2 [a(1) + a(n)]
For n = 5
S(5) = 5/2 (4 + 16)
S(5) = 5/2 . 20 = 50

the correct statement is the first one.
The inverse of 6^2 is 6^(1/2), then 6^(1/2) is the square root of 6.
Which statement explains why 6^(1/2) is equal to √6?Well, this is just a notation thing.
We know the following property for exponents:
(a^n)^m = a^(n*m)
And we know that the square rooth is the inverse of the square power (exponent equal to 2) such that:
√x^2 = 2
Then if we define the square root as an exponent, let's say that is an exponent "a" we will have:
√x = x^a
Rewritting the above relation again, we can write:
√(x^2) = (x^2)^a = x^(2*a)
And we know that it must be equal to x, so we get:
x^(2*a) = x
This means that 2*a = 1
then a = 1/2
√x = x(1/2)
Then the correct statement is the first one.
The inverse of 6^2 is 6^(1/2), then 6^(1/2) is the square root of 6.

b. What is the volume of the larger can? Round to the nearest tenth.
The volume of the larger cylindrical can of tuna with radius 5.2 centimeters is 419.6 cubic centimeters.
Solids of the same type that have proportional corresponding linear measures are similar solids. In the case of similar cylinder:
height of A / height of B = radius of A / radius of B
Using this scale, if the larger and similar can of tuna has a radius of 5.2 centimeters, and the small cylindrical can of tuna has a radius of 4 centimeters and a height of 3.8 centimeters, then:
radius of larger cylinder / radius of smaller cylinder = 5.2 cm/4cm = 13/10
height of larger cylinder / height of smaller cylinder = 13/10
height of larger cylinder = 13/10 (3.8 cm)
height of larger cylinder = 4.94 cm
Solving for the volume of the larger can using the formula for the volume of cylinder:
V = πr^2h
V = π(5.2 cm)^2(4.94 cm)
