Which of the following is a step in constructing a circle inscribed in a triangle? (6 points) Use a compass to locate the inters

ection of the midpoint of each side. Use the perpendicular bisectors to find the center of the circle. Use a compass to locate the intersection of the altitude of each side. Use the angle bisectors to find the center of the circle.

Answer:

d) Use the angle bisectors to find the center of the circle.

Step-by-step explanation:

Given that for a triangle a circle inscribed in a triangle is to be drawn.

For a incircle we must have the centre of the circle equidistant from the sides.

Then only the circle will touch all the three sides.

To get a point equidistant from all the three sides we must choose a point which lie on the three angle bisectors of the triangle.

Since angle bisectors are concurrent in a triangle, we can draw any two angle bisectors.

Option d is right

1. Daniel is working on a project for his math class. He is working with the rational
Hatshy [7]

Using translation concepts, it is found that the function that would meet Daniel's needs is:

g(x) = -cf(x) - b, c > 1, b > 0

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

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, the parent function is f(x).

The transformations are as follows:

  • Vertical stretch, hence the function has to be multiplied by a constant c that is greater than 1, that is, g(x) = cf(x),  c > 1.
  • Reflection over the x-axis, hence the function is multiplied by -1, that is, g(x) = -cf(x), c > 1.
  • Shift down, hence a constant b is subtracted from the graph, that is, g(x) = -cf(x) - b, c > 1, b > 0.

Dom runs a pizza business. Last year he took in $88 000 and it cost him $33 000
Natali [406]

Answer:

The percentage profit for the year is 62.50%

Step-by-step explanation:

Here, we want to calculate the percentage profit

That would be difference between the revenue (88,000) and the cost (33,000) divided by the revenue * 100%

We have this as;

(88,000-33,000)/88,000 * 100%

= 55,000/88,000 * 100%

= 62.50%

How many 2-letter combinations can be created from the distinct letters in the word "mathematician"? Assume that the
Rzqust [24]

Answer:

Option A.

Step-by-step explanation:

The given word is "mathematician".

Here, total number of letter is 13 and  

Number of distinct letters = 8

We need to select 2 distinct letters from word "mathematician".

It means we need to select 2 letters from 8 distinct letters.

Total ways =^8C_2

=\dfrac{8!}{2!(8-2)!}

=\dfrac{8\times 7\times 6!}{2\times 6!}

=28

Therefore, the correct option is A.
