Answer 1

Step-by-step explanation:

x = number of t- shirts

the function for the incurring costs is

c = 5x + 45

the function for the accumulating sale is

s = 20x

the break even point is when both functions deliver the same result.

20x = 5x + 45

15x = 45

x = 3

c = s = 5×3 + 45 = 20×3 = $60

they need to sell 3 t-shirts to break even.

at that point they will have incurred $60 in costs and collected the same amount in sales.

Find the center and radius of a circle that has a diameter with the given endpoints.

(7, -5) and (-1, 10)

Answers

Answer:

center: (3, 2.5)radius: 8.5 units

Step-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.

How many committees can be formed by choosing 4 men from an organization of a membership of 15 men?


​

Answers

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 selection

The 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

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

Answers

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.
