Triangle P Q R is shown. Angle P Q R is a right angle. The length of Q R is p, the length of R P is q, and the length of P Q is r. Which sine ratios are correct for ΔPQR? Check all that apply.
A. sin (P) = StartFraction r Over q EndFraction
B. sin (P) = StartFraction p Over q EndFraction
C. sin (Q) = StartFraction r Over p EndFraction
D. sin (R) = StartFraction q Over r EndFraction
E. sin (R) = StartFraction r Over q EndFraction
Step-by-step explanation:
answer is in the picture
Option A (sin(P) = r/q), Option C (sin(Q) = r/p), and Option D (sin(R) = q/r) are correct sine ratios for ΔPQR. Option B (sin(P) = p/q) and Option E (sin(R) = r/q) are not correct sine ratios for ΔPQR.
To determine the correct sine ratios for ΔPQR, let's recall the definitions of sine for each angle in a right-angled triangle.
In a right-angled triangle ΔPQR:
1. sin(P) = opposite side / hypotenuse = r / q (Correct) [By definition of sine in a right triangle, sin(P) = opposite/hypotenuse]
2. sin(Q) = opposite side / hypotenuse = r / p (Correct) [By definition of sine in a right triangle, sin(Q) = opposite/hypotenuse]
3. sin(R) = opposite side / hypotenuse = q / r (Correct) [By definition of sine in a right triangle, sin(R) = opposite/hypotenuse]
Option A (sin(P) = r/q), Option C (sin(Q) = r/p), and Option D (sin(R) = q/r) are correct sine ratios for ΔPQR. Option B (sin(P) = p/q) and Option E (sin(R) = r/q) are not correct sine ratios for ΔPQR.

How many committees can be formed by choosing 4 men from an organization of a membership of 15 men?
The selection of the committee members is an illustration of combination
There are 150150 different ways of selecting the committee
How to determine the total selectionThe number of members (n) is:
n = 15
The members on the committee are (r):
r = 4
So, the number of selection is:
[tex]^nC_r = \frac{n!}{(n - r)!r!}[/tex]
This gives
[tex]^{15}C_4 = \frac{15!}{(15 - 4)!4!}[/tex]
Evaluate the differences
[tex]^{15}C_4 = \frac{15!}{9!4!}[/tex]
Expand
[tex]^{15}C_4 = \frac{15* 14 * 13 * 12 * 11 * 10 * 9!}{9!4!}[/tex]
This gives
[tex]^{15}C_4 = \frac{15* 14 * 13 * 12 * 11 * 10}{4!}[/tex]
[tex]^{15}C_4 = 150150[/tex]
Hence, there are 150150 different ways of selecting the committee

as the question told you, if there're 5 counselors, there's a maximum for students of 15. and for 15 counselors, there's a maximum for students of 45. we can easily see that every one counselor can only have 3 students. therefore, you should draw each dot with respect to the counselors' amount, but because two points determine one line, all you need to do is draw (5,15), (15,45) and line them from 0 to 50.

Find the center and radius of a circle that has a diameter with the given endpoints.
(7, -5) and (-1, 10)
Answer:
center: (3, 2.5)radius: 8.5 unitsStep-by-step explanation:
The center of a circle is the midpoint of any diameter. The midpoint of a segment has coordinates that are the average of the coordinates of the segment end points.
The length of the radius is the distance from the center to an end point of a diameter. Alternatively, it is half the length of the diameter.
__
Center = (A +B)/2 = ((7, -5) +(-1, 10))/2 = (6, 5)/2 = (3, 2.5)
Radius = 1/2|AB| = 1/2√((7 -(-1))² +(-5 -10)²) = 1/2√(64 +225) = 1/2√289
= 17/2 = 8.5
The center of the circle is (3, 2.5), and the radius is 8.5 units.
__
Additional comment
The differences of diameter end point coordinates are 8 and 15, suggesting the Pythagorean triple {8, 15, 17} will come into play. It does.

[tex]\textsf{quotient rule: }a^b \div a^c=a^{(b-c)}[/tex]
[tex]\textsf{power rule: }(a^b)^c=a^{(b \times c)}[/tex]
a) Use product rule:
[tex]3^2 \times 3^x=3^{(2+x)}[/tex]
[tex]\implies 3^{(2+x)}=3^7[/tex]
[tex]\implies 2+x=7[/tex]
[tex]\implies x = 5[/tex]

[tex]7^8 \div 7^y=7^{(8-y)}[/tex]
[tex]\implies 7^{(8-y)}=7^6[/tex]
[tex]\implies 8-y=6[/tex]
[tex]\implies y=2[/tex]
