Please remember the rule of dilation
If a point (x,y) dilated for the scale factor of 'k', we do get image as (kx,ky)
Using this concept, we know scale factor is [tex]\frac{1}{2}[/tex] , we could get image as [tex](\frac{1}{2} (-8), \frac{1}{2} (-2))[/tex]
Let's simplify it
We do get (-4,-1)
PLEASE HELP!! A circle is divided into three central angles that have measures in the ratio 2:13:15. find the measure of the largest angle.
Answer:
First angle = 24'
Second angle = 156'
Third angle = 180'
Step-by-step explanation:
Given:
Ratio of circles angle = 2:13:15
Find:
All three angle
Computation:
Sum of all angle from center = 360'
So,
First angle = 360[2/(2+13+15)]
First angle = 360[2/(30)]
First angle = 24'
Second angle = 360[13/(2+13+15)]
Second angle = 360[13/(30)]
Second angle = 156'
Third angle = 360[15/(2+13+15)]
Third angle = 360[15/(30)]
Third angle = 180'
What is m∠G to the nearest tenth?
Answer: The answer is 133.4 degrees.
Sorry if it’s wrong, and hopes this is helps.
The measure of the angle ∠G to the nearest tenth will be 31.6°.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.
The length of the perpendicular is 28.2 units and the length of the base is 45.8 units, Then the measure of the angle ∠G is calculated as,
tan G = Perpendicular / Base
Substitute the value, then the angle is given as,
tan G = 28.2 / 45.8
tan G = 0.6157
G = 31.6°
The measure of the angle ∠G to the nearest tenth will be 31.6°.

Let's start form the product `x^{2}+11x+30,` and get back to the binomials we started with. Show your steps.
Answer:
Then, the polynomial [tex]x^{2}+11\cdot x + 30[/tex] is equal to the product of the binomials [tex](x+5)[/tex] and [tex](x+6)[/tex].
Step-by-step explanation:
The polynomial [tex]x^{2}+11\cdot x + 30[/tex] is a polynomial of the form [tex]x^{2} - (r_{1}+r_{2})\cdot x + r_{1}\cdot r_{2} = (x-r_{1})\cdot (x-r_{2})[/tex], where [tex]r_{1}[/tex] and [tex]r_{2}[/tex] are the roots of the polynomial. Then, we find the following system of equations:
[tex]-r_{1}-r_{2} = 11[/tex] (1)
[tex]r_{1}\cdot r_{2} = 30[/tex] (2)
After some algebraic handling, the solution of this system is [tex]r_{1} = -5[/tex] and [tex]r_{2} = -6[/tex].
Then, the polynomial [tex]x^{2}+11\cdot x + 30[/tex] is equal to the product of the binomials [tex](x+5)[/tex] and [tex](x+6)[/tex].

Solve the simultaneous equation
Log(x-1)+2 log y=2 log 3
Log x + log y = log 6
Answer:
x = 2, y = 3
Step-by-step explanation:
Log x + log y = log 6 Log xy = Log 6 xy = 6
y = 6/x
Log(x-1)+2 Log y=2 Log 3
Log(x-1) = 2 Log 3 - 2 Log y = Log 3² - Log y² = Log 9 - Log y² = Log (9 / y²)
x - 1 = 9/y²
x - 1 = 9 / (6/x)² = 9 /(36/x²) = x²/4
4x - 4 = x²
x² -4x + 4 = 0
(x-2)² = 0
x = 2
y = 6/x = 3

Answer:
x = - 8 and (- 8, 0 )
Step-by-step explanation:
Given a quadratic in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the equation of the axis of symmetry which is also the x- coordinate of the vertex is
x = - [tex]\frac{b}{2a}[/tex]
y = x² + 16x + 64 ← is in standard form, with
a = 1 and b = 16, then
x = - [tex]\frac{16}{2}[/tex] = - 8
Equation of axis of symmetry is x = - 8
Substitute x = - 8 into the quadratic and evaluate for y
y = (- 8)² + 16(- 8) + 64 = 64 - 128 + 64 = 0
vertex = (- 8, 0 )

A river guide buys protein bars and bottles of water for participants on a rafting trip. Including taxes, the river guide pays $ 2.50 for each protein bar and $ 1.25 for each bottle of water, spending a total of exactly $ 22.50 . Which combinations of protein bars and bottles of water are possible for the given amounts? Select ALL that apply.
Answer:
Step-by-step explanation:
2.50 for water
1.25 for protein bar interesting that is exactly half of the water
22.50 exactly was spent
I couldn't come up a slick equation, so I just applied some logic and used brute forced (trail and error) to solve the problem.
2.5Water + 1.25Protein = 22.5
8W + 2P = 22.5
6W + 6P = 22.5
4W + 10P = 22.5
2W + 14P = 22.5
There are the possible combinations of both protein bars AND water, since he bought both. He could have also bought 10 water or 18 protein bars, but that is not part of the combination.

Pam's eye–level height is 256 feet above sea level and Adam's eye–level height is 400 feet above sea level. What expression shows how much farther Adam can see to the horizon? In simplest terms, Adam can see a√b feet farther than Pam.
Answer:
B
A=2
B=6
Step-by-step explanation:
The expression that shows how much farther Adam can see to the horizon should be considered as the d = 400 - 256 and d = 256 - 400.
Calculation of the expression:Since
Pam's eye–level height is 256 feet above sea level and Adam's eye–level height is 400 feet above sea level.
So here the expression be like The expression that shows how much farther Adam can see to the horizon should be considered as the d = 400 - 256 and d = 256 - 400.

Answer:
Uriel's stick is LONGER by 7/24 feet
Step-by-step explanation:
Uriel's hiking stick is 3 2/3 feet long, and Nat's is 3 3/8 feet long. Whose walking stick is longer and by how much?
The above question is solved as
Uriel's stick - Nat's stick
= 3 2/3 feet - 3 3/8 feet
= 7/24 feet
Hence, Uriel's stick is LONGER by 7/24 feet
