△BOK∼POS. Identify the coordinates of K and the scale factor.
O = 0, 0
B = 5, 0
P = 8, 0
S = 0, -12
Answers
The coordinates of K = (0, -7.5) and the scale factor is 8/5.
Consider the following figure of triangles.
△BOK and ΔPOS.
Since △BOK∼ ΔPOS, the sides of △BOK and ΔPOS must be in proportion. (from definition of triangle similarity)
i.e., OP / OB = OS / OK = PS/BK
Consider an equation,
OP / OB = OS / OK
From the diagram:
OP = 8, OB = 5, OS = 12
Substitute these values in above equation.
8/5 = 12/OK
OK = 60/8
OK = 7.5
We can observe that OK is the distance of point K from origin 'O'
So, the coordinates of K would be (0, -7.5)
And the scale factor is 8/5.

The response to the given domain range questions is [go f oh]. (9) = 5(18^2 - 1 )
What are the domain and range?Domain and range. A function's authorised range of values is known as its domain. The x values in a function like f make up this set (x). A function's range is the collection of values that it can take as input. When we enter an x value, the function outputs this set of values.
According to the given information:f(x) = x^5 – 1, g(x) = 5x^2, and h(x) = 2x
[g o f o h](9)=g(f(h(9))
Let's find h(9) first
h(x)= 2x
h(9)= 2(9) =18
Now plug in 18 for h(9)
[g o f o h](9)=g(f(h(9)) = g(f(18))
now we find f(18)
f(x) = x^5 – 1, f(18)= 18^5 -1
Now we plug in 18^5 -1 for f(18)
[g o f o h](9)=g(f(h(9)) = g(18^5 -1)
Plug it in g(x)
g(x)= 5x^2

Estimate 91 +94 by first rounding each number to the nearest ten.
Answers
90+90=180
Answer:
about 180
Step-by-step explanation:
(when rounding, numbers 0-4 "stay" meaning you'd round down. If the numbers are 5-9, you round up)
91 rounded to the nearest ten would be 90
94 rounded to the nearest ten would be 90 as well
So, 90 + 90 = 180
Technically though, 91+94 = 185. So rounding this to the nearest ten would be 190.

C. The system has a unique solution at (0,-4).
D. The system has infinitely many solutions.
Answers
The statement that is true on the system of equations is that A. The system has no solution.
Why is there no solution ?There is no solution in the given system of equations because the lines formed by the equations are parallel to each other. This means that they will never intersect with each other.
A solution is only derived at the points where the systems of equations intersect with each other. As there is no point where these equations intersect, it means there is no solution for these system of equations.

Write an equation of the line passing through the point (1,8) and parallel to y=−3x+10
Answers
The equation of the line is 3x + y - 11 = 0.
The slope-intercept formula y = mx + b is used when you know the slope of the line to be examined and the point given is also the y intercept (0, b). In the formula, b represents the y value of the y intercept point.
First we find the slope of the line y=-3x+10 by placing it into slope-intercept form:
y = -3 x + 10
Therefore, the slope of the line is m= -3
Now since the equation of the line with slope m passing through a point
(x₁ ,y₁) is y-y₁ = m(x-x₁)
Here the point is (1,8) and slope is m= -3, therefore, the equation of the line is:
y - 8 = -3(x - 1)
y - 8 = -3x +3
3x + y - 11 = 0
Hence, the equation of the line is 3x + y - 11 = 0.

(1 - sinθ)/ cosθ = 1/cosθ - sinθ / cosθ = secθ - tanθQuestion 2The first part without root:
(1 + cosθ) / (1 - cosθ) = (1 + cosθ)(1 + cosθ) / (1 - cosθ)(1 + cosθ) (1 + cosθ)² / (1 - cos²θ) = (1 + cosθ)² / sin²θIts square root is:

The direction of this transmission is always determined by the temperature differential between the bodies.
To achieve an equilibrium temperature, heat is transferred from the hotter to the cooler body.

Liam Brought 5/8 Pound of cherries. Harrison Brought more cherries than Liam. Which could be the amountOf cherries that Harrison brought ?
Answers
The amount of cherries bought by the Harrison is 62.5 pounds.
A fraction is a part of a whole. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator.
The amount of cherries bought by the Harrison should be more than the cherries bought by the Liam which is 5/8. Thus, The amount of cherries bought by the Harrison is more than the 5/8 or 62.5 pounds of cherries percent.
The cherries bought by the Liam is 5/8 pounds
The cherries bought by the Harrison is more than the Liam.
As in the problem the number of cherries bought Harrison (let) should be more than the cherries bought by the Liam (let ). Therefore,
H > L
As we know that the number of cherries bought by the Liam is 5/8 pounds. Keep the value of in the above equation, we get,
H > 5/8
This equation can be rewritten in the percentile form as,
h > (5/8) * 100 %
h > (5/2) * 25 %
h > 62.5 %
Hence, The amount of cherries bought by the Harrison is more than 5/8 pounds or 62.5 pounds of cherries percent.

The Almighty Formula
= -b ± √b² - 4ac/2a
Where ax + bx² + c = 0
From the above question
a = 1, b = 4, c= 7
Hence,
-4 ± √4² - 4 × 1 × 7/2 × 1
-4 ± √16 - 28/2
=( -4 ± √-12)/2
Since
b² - 4ac < 0
We have two complex roots
Simplifying
( -4 ± √-12)/2
= -4/2 ± √-12/2
= -2 ± 2√3i/2
= -2 ± √3i
Therefore,
