Give one example of when you would use the friendly numbers strategy to subtract

In isosceles ∆ABC, points M and N belong to base

Anvisha [2.4K]

From the statements and reasons given below as regards the Isosceles Triangle, we have been able to prove that; ∆BAM ≅ ∆CAN

<h3>How to prove an Isosceles Triangle?</h3>

Isosceles Triangle means that two sides of the triangle are equal and also 2 angles are equal.

Now, we are told that triangle ABC is an Isosceles and as such, AB and AC are congruent.

We are given that BM and NC are congruent. Now, due to the fact that Triangle AMN is an isosceles triangle, it means that the sides AM and AN are congruent to each other.

Thus, from the proofs above and from the definition of the isosceles Triangle, we can say that triangles BAM and CAN are congruent.

The following diagram represents all of the stages of a shrinking iceberg. The iceberg is circular, and when it started out, it

A geometric progression is a sequence that involves a rate, causing a change in the subsequent values of the sequence with respect to the given rate.

The answers to the given question are as follows:

a. It is a geometric progression.

b. Radius of the 6th circle ≅ 23. 73 ft.

c. The total length, l, can be determined by: l = ∑0.75 $R_{i}$ , i = 1 to n.

Geometric progression involves a change in the subsequent values of a given sequence due to a rate. So considering the given question, the circular iceberg melts at a certain rate per hour. Thus its radius decreases at the given rate per hour.

a. Therefore it can be deduced that the question is on geometric progression.

b. To determine the radius of the 6th circle, the:

radius of the 1st circle = 100 ft

radius of the 2nd circle = 0.75 x 100

= 75 ft

radius of the t3rd circle = 0.75 x 75

= 56.25 ft

radius of the 4th circle = 0.75 x 56.25

= 42.1875 ft

radius of the 5th circle = 0.75 x 42.1875

= 31.640625 ft

radius of the 6th circle = 0.75 x 31.640625

= 23.73046875 ft

Thus the radius of the 6th circle is approximately 23. 73 ft.

c. Since the process is assumed to continue forever, let the number of hours required to be represented by n, and each radius of the iceberg be represented by R.

So then, we can say that the total length, l, of all the circles' radii is will be given by:

l = ∑0.75 $R_{i}$ , i = 1 to n

Matilda has been studying exponential functions in her algebra class and has started to notice a pattern.

dlinn [17]

Answer:

Most likely C

Step-by-step explanation:

This is most likely C because it always goes up and although a and c are the only ones with positive equations a makes you multiply by a decimal which can reduce the number so it's most likely C

If you flip the graph of the absolute value parent function, f(x)=|x|, over the x-axis, what is the equation of the new function

Natalija [7]

The equation of the new function is f'(x) = -|x|

<h3>How to determine the equation of the new function?</h3>

The function is given as:

f(x) = |x|

The rule of flipping the graph over the x-axis

(x, y) = (x, -y)

So, we have:

f'(x) = -f(x)

Substitute f(x) = |x|

f'(x) = -|x|

Hence, the equation of the new function is f'(x) = -|x|
