rotate (2,-3) 270 degree counterclockwise around (1,-2) then translate (x-2,y+5)
The image point of the transformation is (-1, 6)
How to determine the image of the transformation?The coordinate of the point is given as
(2, -3)
The transformations are given as
270 degree counterclockwise around (1,-2) Translation by (x-2,y+5)The rotation is around the point (1,-2)
So, the point becomes
Point = (2 - 1, -3 + 2)
Evaluate
Point = (1, -1)
The 270 degrees rotation has the algebraic rule of its rotation to be changed from (x, y) to (-y, x) i.e. (x, y) => (-y, x)
So, we have
(x, y) = (1, 1) after the rotation
The translation is given as
(x - 2, y + 5)
So, we have
(x, y) = (1 - 2, 1 + 5)
Evaluate
(x, y) = (-1, 6)
Hence, the coordinates of the image is (-1, 6)

Determine the equation of the parabola that opens up, has vertex (7, 7), and a focal
diameter of 16.
Answer:
Step-by-step explanation:
Question: Determine the equation of the parabola that opens up, has vertex (7,7), and a focal diameter of 16 . This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts.
Answer: ((x2)−14x+87)/16
Step-by-step explanation:
focal diameter = 16,
4a=16;
a=4.
(h,v)=(7,7-a)
==> (h,v)=(7,3)
the equation of the parabola = ((x-7)^2)=16(y-3)
=> y = ((x^2)-14x+87)/16.
Solve for x. Leave your answer in simplest radical form.
Answer:
√122
Step-by-step explanation:
first we have to find the missing side with x on the 5 and 9 triangle by using the theorem
a^2+b^2=c^2
9^2+5^2=c^2
81+25=c^2
106=c^2
√106=c
and now we can use this as a side to find x
4^2+√106^2=x^2
16+106=x^2
122=x^2
√122=x

Find the Maclaurin series of the following functions. Step by Step Please
The Maclaurin series of xcos(-x) up to n = 3 is
[tex]m(x)= xcos(-x)= x-\frac{1}{2}x^3+\frac{1}{24}x^5-\frac{1}{720}x^7+\frac{1}{40320}x^9+\ldots \:[/tex]
The function is given in the question as
m(x) = xcos(-x)
Taylor (Maclaurin) series of xcos(x) up to n=5
A Maclaurin series is given by f(x),
[tex]f\left(x\right)=f\left(a\right)+\frac{f^'\left(a\right)}{1!}\left(x-a\right)+\frac{f^{''}\left(a\right)}{2!}\left(x-a\right)^2+\frac{f^{'''}\left(a\right)}{3!}\left(x-a\right)^3+\ldots[/tex]
[tex]f\left(x\right)=f\left(0\right)+\frac{f^'\left(0\right)}{1!}\left(x\right)+\frac{f^{''}\left(0\right)}{2!}\left(x\right)^2+\frac{f^{'''}\left(0\right)}{3!}\left(x\right)^3+\ldots[/tex]
We need to do to get the desired polynomial is to calculate the derivatives, evaluate them at the given point, and plug the results into the given formula.
f⁽⁰⁾(x) = f(x) = xcos(x)
Evaluate the function at the point: f(0)=0
1st derivative: f(1)(x)=(f(0)(x))′=(xcos(x))′=−xsin(x)+cos(x)
1st derivative at the given point: (f(0))′=1
2nd derivative: f(2)(x)=(f(1)(x))′=(−xsin(x)+cos(x))′=−xcos(x)−2sin(x)
Evaluate the 2nd derivative at the given point: (f(0))′′=0
3rd derivative: f(3)(x)=(f(2)(x))′=(−xcos(x)−2sin(x))′=xsin(x)−3cos(x)
Evaluate the 3rd derivative at the given point: (f(0))′′′=−3
Now, use the calculated values to get a polynomial:
[tex]m(x)=0+\frac{1}{1!}x+\frac{0}{2!}x^2+\frac{-3}{3!}x^3+.....[/tex]
[tex]m(x)=x-\frac{1}{2}x^3+\frac{1}{24}x^5-\frac{1}{720}x^7+\frac{1}{40320}x^9+\ldots \:[/tex]
Thus, the Maclaurin series of xcos(-x) up to n = 3 is
[tex]m(x)= xcos(-x)= x-\frac{1}{2}x^3+\frac{1}{24}x^5-\frac{1}{720}x^7+\frac{1}{40320}x^9+\ldots \:[/tex]

Apply the distributive property to simplify the expression
8(12x – 20)
I believe the answer must be 96x-160
Because we have to multiply 8x12 which is 96. and there is x next to it. so keep the x as it is.
and next to it is minus ( - ) sign so keep it as it is.
now we have to multiply 8x20 which is 160.
so if we write it together it will be:
so if we write it together it will be:96x - 160.

A marching band needs to raise $13,500 for a trip to the Rose Bowl. The director told the band members that one-third of the amount that has been raised so far is equal to half of the amount that is still needed. How much more money needs to be raised for the trip?
Answer: $5400
Step-by-step explanation:
x = amount raised so far
13500 - x = amt. still needed
x/3 = (13500 - x)/2
2x = 3(13500 - x)
2x = 40500 - 3x
5x = 40500
x = 40500/5 = 8100 (amt. raised so far)
13500 - 8100 = 5400 (amt. still needed)

What is the range of the function f(x)=2x^3−3x for the domain {−1, 1, 2}?
The range of the function is {1,-1,10} for function f(x)=2x³−3x .
What is a function?A relation is a function if it has only One y-value for each x-value.
In a function what can go into a function is called the Domain. What may possibly come out of a function is called the Codomain. What actually comes out of a function is called the Range.
The given function is f(x)=2x³−3x
The domain is {-1,1,2}
Now f(-1)=2(-1)³-3(-1)
=-2+3=1
f(1)=2(1)³-3(1)=2-3=-1

In terms of angles, it is written as ratios of the sine, cosine, tangent, secant, and cotangent angles. A trigonometric equation is, for instance, cos2 x + 5 sin x = 0.
For angle 30 degrees adjacent side is 18 yard and opposite side is x.

The vertex angle of an isosceles triangle measures
15 degrees more than one of its base angles. How
many degrees are there in a base angle of the
triangle?
The required three angle is 55 , 55 and 70
What is an angle ?
An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.
When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together. The Latin word "angulus," which means "corner," is where the term "angle" originates.
Let each of the base angle of isosceles triangle = x
Vertex angle = (x+15)
Sum of the angle = 180
x + x + (x + 15) = 180
3x + 15 = 180
3x = 180 - 15
x = 165 / 3
x = 55
Each base angel = 55
Vertex angle = x + 15
= 55 + 15
= 70
Required three angles = 55 , 55 and 70
