Answer:
The bacterial culture loses of its size every 7 seconds.
Step-by-step explanation:
The relationship between the elapsed time t, in seconds, and the number of bacteria, N(t), in the petri dish is modeled by the function:
Since the growth factor is less than 1, it is a decay equation.
Observe that the time t is divided by 7.
This is the period.
We can therefore say that the bacterial culture loses of its size every 7 seconds.
4. Multiple Representation Write a different equation to find the angle measures in Example 2. Will the answer be the same? Explain.
As we know that the sum of angles of a triangle is 180⁰.
In Mathematics, an equilateral triangle:
From the given equilateral triangle, the equation can be written as:
x + x + x = 180⁰
As each angle is 60°.
so
60° + 60° + 60° = 180⁰
Therefore, each angle measure = x = 60°.
Yes! the answer is same, as the sum of angles of a triangle is 180⁰. The reason is that an equilateral triangle is said to be a triangle in which all three sides are equal. All three internal angles are also congruent to each other, each having 60° measure.
<h2> Question # 5</h2>5. Draw Conclusion Triangle ABC is a right triangle. What conclusion can you draw about the measure of the angles of the triangle.
The Pythagorean Theorem defines the relationship in every right triangle such as:
A right isosceles triangle - having two same sides - has a 90° angle and two 90° angles.
Another kind of right triangle is the 30-60-90 degree triangle. Where one angle is right, 90°, and other two angles are 30° and 60°.
Another kind of right triangle is the 45-45-90 degree triangle. Where one angle is right, 90°, and other two angles are 45° and 45°.
So, we conclude that we have a variety of right triangles where one angle is the right angle, measuring 90° angle.
