Given: NQ¯¯¯¯¯¯¯¯ is the bisector of ∠MNP and ∠NMQ≅∠NPQ
Prove: △MNQ≅△PNQ
Answers
△MNQ ≅ △PNQ by SAS congruence theorem.
What is the SAS Congruence Theorem?If two triangles are congruent by the SAS congruence theorem, then they have two pairs of corresponding congruent sides and a pair of corresponding included sides that are congruent.
∠MNQ ≅ ∠PNQ [congruent angles formed by angle bisector]
Therefore, opposite sides to the angles, MQ and PQ would also be congruent.
Thus, MQ ≅ PQ
NQ ≅ NQ [reflexive property]
This means that both triangles have two pairs of corresponding congruent sides and a pair of corresponding included sides that are congruent.
Thus, △MNQ ≅ △PNQ by SAS congruence theorem.

The following diagram represents all of the stages of a shrinking iceberg. The iceberg is circular, and when it started out, it had a radius of 100 feet. The iceberg shrank to a radius that was 75% of its original size every hour. Each circle in the drawing represents the size of the iceberg in each of the successive hours it was shrinking. Using this information, answer the questions having to do with the image:
a. Is this a geometric series or an arithmetic series? Explain why you chose this answer.
b. Describe the steps you would use to calculate the radius of the 6th circle.
c. Assuming this pattern continued forever, what would be the total length if you added all of the circles’ radii* together? Explain your answer.
Answers
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[tex]R_{i}[/tex], 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[tex]R_{i}[/tex], i = 1 to n

how to convert whole number as fraction
Answers
To convert an integer to a fraction you must choose an expression that does not alter the numerical value. You can do this with multiples of the number, for example, for 100:
100/1 = 200/2 = 300/3 = 400/4 = 100
The numerical value is not altered and the result will always be 100
Another example, for 500:
500 = 500/1 = 1000/2 = 1500/3 = 2000/4

3. Try It #3 Write the point-slope form of an equation of a line with a slope of -2 that passes through the point (-2,2). Then rewrite it in the slope-intercept form.
Answers
Answer:
Point-slope form of equation given as [tex]$y-2=-2(x+2)$[/tex].
Slope-intercept form of equation is given as [tex]$y=-2 x-2$[/tex].
Step-by-step explanation:
In the question, it is given that the slope of a line is -2 and it passes from (-2,2).
It is asked to write the point-slope form of the equation and rewrite it as slope-intercept form.
To do so, first find the values which are given in the question and put it in the formula of point-slope form. Simplify the equation to rewrite as slope-intercept form.
Step 1 of 2
Passing point of the line is (-2,2).
Hence, [tex]$x_{1}=-2$[/tex] and
[tex]$$y_{1}=2 \text {. }$$[/tex]
Also, the slope of the line is -2.
Hence, m=-2
Substitute the above values in point-slope form of equation given by [tex]$y-y_{1}=m\left(x-x_{1}\right)$[/tex]
[tex]$$\begin{aligned}&y-y_{1}=m\left(x-x_{1}\right) \\&y-2=-2(x-(-2) \\&y-2=-2(x+2)\end{aligned}$$[/tex]
Hence, point-slope form of equation given as y-2=-2(x+2).
Step 2 of 2
Solve y-2=-2(x+2) to write it as slope-intercept form given by y=mx+c.
[tex]$$\begin{aligned}&y-2=-2(x+2) \\&y-2=-2 x-4 \\&y=-2 x-4+2 \\&y=-2 x-2\end{aligned}$$[/tex]
Hence, slope-intercept form of equation is given as y=-2x-2.

Using the circle theorems, we have proven that m ∠RTW = 15°
Circle theoremsFrom the question, we are to prove that m ∠RTW = 15°
In the given diagram,
measure of arc ST = 30°
∴ m ∠SRT = 30°
m ∠SRT = ∠T + ∠W ( Exterior angle of a triangle equals the sum of the two remote angles)
Also,
∠T = ∠W (Radii of the same circle)
∴ m ∠SRT = ∠T + ∠T
m ∠SRT = 2 × ∠T
30° = 2 × ∠T
∠T = 30° /2
∠T = 15°
∴ m ∠RTW = 15°

Answer:
B- Jenny must have driven more than 48 miles.
Step-by-step explanation:
If Jenny rode for 60 at 48 mph, it would be exactly 48 miles. Though there is only 60 minutes in an hour, and Jenny rode 5 minutes longer than that, her drive being 65 minutes. To find how much she rode, 5 extra minutes into an hour would divide equally into 60, resulting in 12. Divide 48 by 12, and Jenny would have driven 4 miles in the 5 minutes drive after 60 minutes.

Computing the Equivalent Logarithmic Equation
The given exponential equation is,
[tex](4)^{c} = 256[/tex]
As per the fundamental properties of exponentiation, the logarithmic equivalent equation of any exponential equation has the same base as that in the corresponding exponential equation. Exponentiation refers to the act of raising a number to the power of another number.
In the exponential equation, [tex](4)^{c} = 256[/tex], $ is the base. So, the base in its equivalent logarithmic equation will also be 4.
The result of the exponential expression becomes the operand for the log.
