Answer:

Incentre

Step-by-step explanation:

A triangle is a closed area in a plane bounded by three lines known as sides of a triangle.

There will be 3 angles in a triangle.

Consider the point of concurrency of three bisectors.

Let ABC be one triangle and AI and BI are bisectors of A and B meeting at I.

Then we have since AI is angle bisector of A, I would be equidistant from sides BA and AC. Similarly since BI is angle bisector of B, I would be equidistant form BC and BA.

It follows that I is equidistant from all the sides, and hence a centre can be drawn touching all sides of the triangle.

The circle is called in circle and the point I, the point of concurrency of the angle bisectors of a triangle, is the incentre of the triangle.

Choose the slope-intercept equation of the line that passes through the point (4, -6) and is parallel to y = - 1/2 x + 5. (3 poi

telo118 [61]

First, it is important to understand that parallel lines have the same slope. Therefore, based on the formula y=mx+b in which m represents slope and based on the equation y=-1/2x+5, the slope of the unknown line is also -1/2. Then, there are two different ways to solve this problem using different formulas.

The first method to find the unknown equation is easy but not widely known. We can use the point slope formula which is (y-y1)=m(x-x1) in which we can plug a point and slope to find the equation. When we plug in the values given, we get y+6=-1/2(x-4) or y+6 =-1/2x+2 which simplifies to y=-1/2x-4.

The other method is using the slope intercept form or y=mx+b. When we plug in our slope and our point, we get -6=-1/2*4+b or -6=-2+b so b must equal -4, therefore we have all the information we need to plug values into y=mx+b. When we plug in our slope and y-intercept, we get y=-1/2x-4 which is the answer.

I hope this helps!

The order of transformation which best describes how to sketch the graph of h(x) = ∛1 - x is: A. Starting with the graph of the basic function y = ∛x, horizontally shift the graph to the left one unit, and then reflect the graph about the y-axis.

<h3>The types of transformation.</h3>

Generally, there are different types of transformation and these include the following:

Rotation
Translation
Dilation
Reflection

<h3>What is a reflection?</h3>

A reflection can be defined as a type of transformation which moves every point of the object by producing a flipped but mirror image of the geometric figure.

In this context, we can reasonably infer and logically deduce that the order of transformation which best describes how to sketch the graph of h(x) = ∛1 - x is to start by plotting the graph of the basic function y = ∛x, and then horizontally shift the graph of function y = ∛x to the left one unit, and then reflect the graph about the y-axis.

Complete Question:

Which of the following order of transformations best describes how to sketch the graph of h(x) = ∛1 - x?

A. Starting with the graph of the basic function y = ∛x, horizontally shift the graph to the left one unit, and then reflect the graph about the y-axis.

B. Starting with the graph of the basic function y = ∛x, vertically shift the graph up one unit, and then reflect the graph about the y-axis.

C. Starting with the graph of the basic function y = ∛x, horizontally shift the graph to the left one unit, and then reflect the graph about the x-axis.

D. Starting with the graph of the basic function y = ∛x, horizontally shift the graph to the right one unit, and then reflect the graph about the y-axis.

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!! I CANNOT RETAKE THIS!!

vazorg [7]

500 (2^(t/12)) = 800 , where t is in hours
2^(t/12) = 1.6
take logs of both sides, and use the rules of logs
t/12 log2 = log 1.6
t/12 = log 1.6/log 2
t = 12(log 1.6/log 2)
= appr 8.1 hours

(btw not sure about this)
