How do you number 3 and can you explain everything for detail please

Answers

-y = x + 3   . . . . this is the sides for the double lines

2y + 24 = x + 9 . . . . this is the sides for the single lines

To solve you need to substitute one equation into the other

-y = x + 3
y = -x - 3  . . . place this equation into the other equation where (Y) is

2y + 24 = x + 9
2 ( -x - 3) + 4 = x +9
-2x - 6 + 24 = x + 9
-2x +18= x+9
-3x = -9
x = 3  . . . substitute this answer into the equation and solve for (Y)

-y = x + 3
- y = 3 +3
-y = 3 + 3
 y= -6

Determine whether the infinite geometric series is convergent or divergent. If it is convergent, find its sum. (If the series is divergent, enter DIVERGENT.)

(1)-(1/6)+(1/36)-(1/216)+... ...?

Answers

The geometric series can be rewritten as
1 + (-1/6) + (-1/6)^2 + (-1/6)^3 + ...
Since the magnitude of the common ratio is less than 1. The series is then convergent and it has a sum.

Suppose that a "code" consists of 4 digits, none of which are repeated. (a digit is one of the 10 numbers 0,1,2,3,4,5,6,7,8,9) how many codes are possible?

Answers

The answer is 5040.

This is permutation without the repetition:
P = n!/(n - r)!

n - the number of choices
r - the number of chosen

We have:
n = 10
r = 4

P = 10!/(10 - 4)!
   = 10!/6!
   = (10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1) / (6 * 5 * 4 * 3 * 2 * 1)
   = 10 * 9 * 8 * 7
   = 5040

a radius is a segment that connects any point on the circle to any point inside of that circle

true or false?

Answers

False.

The radius is a line that connects any point on the circle to center. Radius is a constant size line and not line that changes its size therefore it cannot connect any point on circle to any point inside of that circle. 

Answer:

If the question is to the center of that circle instead of "any point inside of that circle" then the answer is true.

Step-by-step explanation:

I got it wrong because I didn't read it all but it is true if it is to any point inside of that circle.

Is this function linear or nonlinear? y=1x

Answers

A linear function is in the form y = mx + b or f(x) = mx + b, where m is the slope or rate of change and b is the y-intercept or where the graph of the line crosses the y axis.  This function is linear, this is because y = 1x is in the form y = mx, there the + b is just + 0 since there is nothing adding into it.

The degree of the function is one. Then function y = x will be a linear function.

at the flower shop, there are 5 times as many roses as sunflowers. if there are 252 roses and sunflowers altogether, how many roses are there? how many sunflowers are there?

Answers

since there are 5 times as many roses as sunflowers, that should mean the sunflower is 1 times.

now you divide 252 and 6 to get 42.

sunflowers= 42

A conical paper cup has dimensions as shown in the diagram. How much water can the cup hold when full?

Answers

94.2 cm divided by pi which is 3.14 equals to 30 evenly hoped this helped yall out

The volume of the conical cup is approximately 94.25 cm³. This is the amount of water it can hold when full.

To find the volume of the conical paper cup, we'll use the formula for the volume of a cone:

[tex]\[ V = \frac{1}{3} \times \pi \times r^2 \times h \][/tex]

Where:

- ( V ) is the volume of the cone

- ( pi ) is a constant (approximately 3.14159)

- ( r ) is the radius of the circular base of the cone

- ( h ) is the height of the cone

Given:

- ( r = 3 ) cm (half the diameter)

- ( h = 10 ) cm

Substituting the given values into the formula:

[tex]\[ V = \frac{1}{3} \times \pi \times (3^2) \times 10 \][/tex]

[tex]\[ V = \frac{1}{3} \times \pi \times 9 \times 10 \][/tex]

[tex]\[ V = \frac{1}{3} \times 90\pi \][/tex]

[tex]\[ V = 30\pi \][/tex]

Now, let's calculate the approximate value of [tex]\( \pi \)[/tex] which is 3.14159:

[tex]\[ V \approx 30 \times 3.14159 \][/tex]

V≈94.2477

So, the volume of the conical paper cup is approximately [tex]\( 94.2477 \, \text{cm}^3 \) or \( 94.25 \, \text{cm}^3 \)[/tex] rounded to two decimal places. This is the amount of water the cup can hold when full.

The length of a rectangle is 6 yards longer than its width. If the perimeter of the rectangle is 32 yd, find its area in square yards.

Answers

Let, width = x
Length = x + 6

Now, perimeter, 2(l+b) = 2(x+6+x)
2(2x+6) = 32
4x + 12 = 32
4x = 20
x = 5 &
x+6 = 5+6 = 11

As rectangle's dimensions are 11*5, it's area would be: 11 * 5 = 55 yards²

So, your final answer is 55 Yd²

Hope this helps!
Final answer:

First, find the width by using the perimeter formula for a rectangle, solve the equation, and then calculate the length by adding 6 yards. With both widths, calculate the area. The rectangle's area is 55 square yards.

Explanation:

To solve for the area of the rectangle, we must find its length and width first. The given condition is that the length is 6 yards longer than the width. If we denote the width as w yards, then the length would be w + 6 yards.

Since the perimeter is the sum of all sides, for a rectangle, it can be calculated by the formula P = 2l + 2w, where P is the perimeter, l is the length and w is the width. Substituting the given perimeter (32 yd) and the expressions for length and width, we have:

32 yd = 2(w + 6 yd) + 2w32 yd = 2w + 12 yd + 2w32 yd = 4w + 12 yd32 yd - 12 yd = 4w20 yd = 4ww = 5 yd (width)l = w + 6 yd = 5 yd + 6 yd = 11 yd (length)

Now that we have both dimensions, the area of the rectangle can be calculated using the formula A = l × w. Substituting the found values:

Area = 11 yd × 5 yd = 55 yd²

Therefore, the area of the rectangle is 55 square yards.

Find the secant of both angle A and angle B.

A. sec A = 13/5; sec B = 13/12
B. sec A = 13/12; sec B = 13/5
C. sec A = 12/13; sec B = 5/13
D. sec A = 24/10; sec B = 10/24

Answers

Final answer:

The secant of angle A is 13/5 and the secant of angle B is 13/12. Option A is correct.

Explanation:

To find the secant of angle A and angle B, we need to use the reciprocal function of cosine which is secant. The secant of an angle is equal to the reciprocal of the cosine of that angle.

So, if sec A = 13/5, it means that the cosine of angle A is equal to 5/13. Similarly, if sec B = 13/12, it means that the cosine of angle B is equal to 12/13.
