Use the vertex ( h, k ) and a point on the graph ( x, y ) to find the standard form of the equation of the quadratic function: Vertex = (-10,-6) Point = (3,-5)
The standard form of the equation of the quadratic function is y = 1/169x² + 20/169² - 5.41.
What is quadratic form of equation?A polynomial with all terms of degree two is known as a quadratic form in mathematics ("form" is another term for a homogeneous polynomial). It is common to refer to a quadratic form over K when the coefficients are typically members of an external factors K, such as the real or complicated numbers.
The vertex form of the quadratic equation is given as:
y = a(x - h)² + k
Substitute the value of the vertex and the point to find the value of a:
-5 = a(3 + 10)² - 6
-5 = a(169) - 6
1 / 169 = a
Substitute the value of a in the equation along with the vertex:
y = 1/169(x + 10)² - 6
y = 1/169(x² + 20x + 100) - 6
y = 1/169x² + 20/169² + 100/169 - 6
y = 1/169x² + 20/169² - 5.41
Hence, the standard form of the equation of the quadratic function is y = 1/169x² + 20/169² - 5.41.

Step-by-step explanation:
Given
\(18e^2f^3-12e^2f\)
Required
Factorize:
\(18e^2f^3-12e^2f\)
Express 18 as 6 * 3 and 12 as 6 * 2
\(18e^2f^3-12e^2f = 6*3e^2f^3-6*2e^2f\)
Factor out 6
\(18e^2f^3-12e^2f = 6(3e^2f^3-2e^2f)\)
Factor out \(e^2\)
\(18e^2f^3-12e^2f = 6e^2(3f^3-2f)\)

Which tool can you use to find the measure of an angle? explain how to use the tool to find the measure of an angle.
The tool which can be used to find the measure of an angle is protractor.
Protractor is a geometrical tool which are basically used to find the measure of an angle.
A protractor consists of angle measures from 0 degree to 10 degrees.
First draw a line segment.
Let the angle we need to measure is 80 degrees.
There will be a point on the middle of protractor from where lines goes all ways.
Put that point on where you need the angle on the line segment.
If the other side of the line is extended to the right of the protractor, measure 80 degrees starting from 0 from the right.
If the line is at the left, do the measure from 0 at the left.
Hence the tool used is protractor.

For each value of u determine whether it is a solution to -2u-6<-20
Answer:
u > 7
Step-by-step explanation:
-2u -6 < -20 Add 6 to both sides
-2u - 6 + 6 < -20 + 6
-2u < -14 Divide both sides by -2. When you multiply or divide both sides by a negative number, you must flig the sign.
\(\frac{-2u}{-2}\) > \(\frac{-14}{-2}\)
u > 7
Helping in the name of Jesus.
The answer is:
u > 7
In-depth explanation:
You haven't told me what the values of u are, but I'll solve the equation for u.
Add 6 on each side:
\(\bf{-2u-6 < -20}\)
\(\bf{-2u < -14}\)
Divide each side by -1 and reverse the sign:
\(\bf{2u > 14}\)
Now divide each side by 2

31. The gravitational force between two bodies is inversely proportional to the square of the distancebetween the bodies. Suppose two objects 12 kilometers apart are attracted by a gravitationalforce of 40 Newtons Use a calculator to determine the gravitational force between the objectswhen they are 8 kilometers apart.
From the question the gravitational force G between two bodies is inversely proportional to the square of the distance d between the bodies.
\(G\propto\frac{1}{d^2}\)using the constant of proportionality k, we have;
\(\begin{gathered} G=\frac{k}{d^2} \\ k=Gd^2 \end{gathered}\)Given;
\(\begin{gathered} d_1=12\operatorname{km} \\ G_1=40N \end{gathered}\)Substituting this value to derive the value k;
\(\begin{gathered} k=Gd^2 \\ k=40(12)^2 \\ k=5760 \end{gathered}\)So, for distance of 8 km, the gravitational force between the bodies is;
\(\begin{gathered} d_2=8\operatorname{km} \\ G_2=\frac{k}{d^2}=\frac{5760}{(8)^2} \\ G_2=90N \end{gathered}\)Therefore, the gravitational force between the objects when they are 8 kilometers apart is 90N
Find the partial derivative of the function f(x,y)=Integral of cos(-7t^2-6t-1)dt. Find fx(x,y) and fy(x,y)
Answer:
\(\mathbf{\dfrac{\partial f}{\partial x}= cos (-7x^2 -6x - 1)}\)
\(\mathbf{\dfrac{\partial f}{\partial y}= cos ( -7y^2 -6y-1)}\)
Step-by-step explanation:
Given that :
\(f(x,y) = \int ^x_y cos (-7t^2 -6t-1) dt\)
Using the Leibnitz rule of differentiation,
\(\dfrac{d}{dt} \int ^{b(t)}_{a(t)} f(x,t) dt= f(b(t),t) *b'(t) -f(a(t),t) * a' (t) + \int^{b(t)}_{a(t)} \dfrac{\partial f}{\partial t} \ dt\)
To find: fx(x,y)
\(\dfrac{\partial f}{\partial x}= \dfrac{\partial }{\partial x} [ \int ^x_y cos (-7t^2 -6t -1 ) \ dt]\)
\(\dfrac{\partial f}{\partial x}= \dfrac{\partial x}{\partial x} cos (-7x^2 -6x -1 ) - \dfrac{\partial y}{\partial x} * cos (-7y^2 -6y-1) + \int ^x_y [\dfrac{\partial }{\partial x} \ \{cos (-7t^2-6t-1)\}] \ dt\)
\(\dfrac{\partial f}{\partial x}= cos (-7x^2 -6x - 1) -0+0\)
\(\mathbf{\dfrac{\partial f}{\partial x}= cos (-7x^2 -6x - 1)}\)
To find: fy(x,y)
\(\dfrac{\partial f}{\partial y}= \dfrac{\partial }{\partial y} [ \int ^x_y cos (-7t^2 -6t -1 ) \ dt]\)
\(\dfrac{\partial f}{\partial y}= \dfrac{\partial x}{\partial y} cos (-7x^2 -6x -1 ) - \dfrac{\partial y}{\partial y} * cos (-7y^2 -6y-1) + \int ^x_y [\dfrac{\partial }{\partial y} \ \{cos (-7t^2-6t-1)\}] \ dt\)
