Select the correct answer. What is the range of y = sin 0 ? Ο Α. B. C. D. [-1.1] [0,⁰0) all real numbers 277
Answers
The range of the sine function is:
R: {x ∈ R| -1 ≤ x ≤1}
It can also be written as [-1, 1], so that is the correct option.
What is the range of the sine function?For a function y = f(x) we define the range as the set of the outputs, this is, the set of the possible values of y.
In this case, our function is y = sin(θ)
Remember that the maximum value of the sine is sin(π/2) = 1
And the minimum is sin(3π/2) = -1
So the maximum value of y is 1 and the minimum is -1, thus, the range is the set of all real numbers between these two, then we can write the range as:
R: {x ∈ R| -1 ≤ x ≤1}
It can also be written as [-1, 1]

Bonds Payable has a balance of $810,000, and Premium on Bonds Payable has a balance of $8,910. If the issuing corporation redeems the bonds at 102, what is the amount of gain or loss on redemption?
a. $8,910 gain
b. $8,910 loss
c. $7,290 loss
d. $7,290 gain
Answers
To determine the gain or loss on the redemption of the bonds, you need to compare the redemption price to the carrying value of the bonds. The carrying value of the bonds is the amount that the bonds are recorded as being worth on the issuing corporation's balance sheet. This is calculated by adding the Bonds Payable balance and the Premium on Bonds Payable balance.
In this case, the carrying value of the bonds is $810,000 + $8,910 = $818,910. If the bonds are redeemed at a price of $102, the gain or loss on the redemption can be calculated as follows:
Gain or loss on redemption = Redemption price - Carrying value of bonds
= $102 - $818,910
= -$817,810
Since the gain or loss on the redemption is a negative number, this indicates that the redemption price was lower than the carrying value of the bonds, resulting in a loss. The correct answer is therefore: c. $7,290 loss.

we want to find the number of hours (or rather days) until only 4.25% of the drives fail.
that means for an exponential distribution we have
P(X < x) = 1 - e^(-Lx)
L = 1/mean = 1/12500
and we need to find x, so that P(X <x) = 0.0425 (that is 4.25% converted into a probability).
so, we get
0.0425 = 1 - e^(-x/12500)
0.0425 - 1 = -e^(-x/12500)
-0.9575 = -e^(-x/12500)
0.9575 = e^(‐x/12500)
ln(0.9575) = -x/12500
-x = ln(0.9575)×12500
x = -ln(0.9575)×12500 = - -0.043429558...×12500 =

A rectangle piece of metal has an area of 32 square centimeters. Its perimeter is 24 centimeters. What are the dimensions of the piece
Answers
The dimensions of the piece are l = 8 and b =4.
What are dimensions?
The minimal set of coordinates required to specify any point within a mathematical space is the dimension of that space. Because only one coordinate is required to specify a point on a line, it has a dimension of one.
Here,
Let the length of a rectangular piece of metal = l cm
And the breadth of a rectangular piece of metal = b cm
Perimeter of a rectangular piece of metal = 2(l+b) = 24 cm
Or, l+b = 24/2
Or, l+b = 12 -------- (1)
Area of a rectangular piece of metal = l×b = 32 cm²
Or, l×b = 32 ------- (2)
We know that,
(l - b)² = (l+b)² - 4×l×b
(l - b)² = (12)² - 4×32
(l - b)² = 144 - 128
(l - b)² = 16
(l - b)² = 4
l - b = 4 --------- (3)
Adding equations (1) and (3), we get
l+b+l-b = 12 + 4
2l = 16
l = 8
Now, we put the value of l in equation(1) and we get
8 + b = 12
b =4
Hence, the dimensions of the piece are l = 8 and b =4.

prove that for every integer exists a multiple of that number that is composed of only ones and zeros in the decimal system
Answers
Let n be a positive integer. Consider the n+1 integers 1,11, 111,1111,... (where the last integer in this list is the integer with n+1 - 1s in its decimal expansion).
Note that there are n possible remainders when an integer is divided by n. Because there are n+1 integers in this list, by the pigeonhole principle there must be two with the same remainder when divided by n. The larger of these integers the smaller one is a multiple of n, which has a decimal expansion consisting entirely of 0s and 1s.
For example, take n=7
we have, 1,11, 111,1111,...,11111111
The remainder possible when any number is divided by 7 is 0,1,2,3,4,5,6
These are the remainders when the numbers in the first list are divided by 7 gives 1,4,6,5,2,0,1,4.
Now you can see that we have 7 pigeonholes {0,1,2,3,4,5,6} and 8 pigeons {1,11, 111,1111,...,11111111} so there needs to be at least one pigeonhole where 2 pigeons will reside.
In this case, we have 11%7=4 and 11111111%7=4
Their difference, i.e. 11111111-11=11111100 is divisible by 7.

Suppose that you roll two dice. You will be paid $20 if you roll a double. You will not receive anything
for any other outcome. How much should you be willing to pay for the privilege of rolling the dice?
Please round your answer to the nearest cent.
Answers
There are 36 possible outcomes when rolling two dice, and only 1 of those outcomes results in a double. Therefore, the probability of rolling a double is 1/36, or approximately 0.028.
If you are willing to pay $20 to roll the dice, then you are effectively paying a premium of $20 for a probability of 0.028 of winning. This means that the expected value of rolling the dice is 0.028 * $20 = $0.56.
Therefore, you should be willing to pay up to $0.56 for the privilege of rolling the dice. Rounded to the nearest cent, this is $0.56.
Window Rock Recruitment Agency just placed Alejandro Rivera in a job as an assistant
pharmacist. The job pays $71,500 annually. The agency fee is equal to 40% of the first
5 weeks' pay. Demonstrate and explain how you would be able to determine what he will
earn during the first 4 weeks if he pays the agency fee weekly?
Answers
Answer: To determine Alejandro's earnings for the first 4 weeks, we first need to calculate his weekly pay. To do this, we divide his annual salary by the number of weeks in a year:
Annual salary / 52 weeks/year = weekly pay
$71,500 / 52 weeks/year = $1,375/week
Next, we need to determine the agency fee that Alejandro will pay each week. The agency fee is equal to 40% of the first 5 weeks' pay, so we multiply Alejandro's weekly pay by 40% to get the agency fee:
Weekly pay * 40% = agency fee
$1,375/week * 40% = $550/week
Finally, to determine Alejandro's earnings for the first 4 weeks, we multiply his weekly earnings by the number of weeks:
Weekly pay * number of weeks = earnings
$1,375/week * 4 weeks = $5,500
So, Alejandro will earn $5,500 during the first 4 weeks of his new job, after paying the agency fee each week.

Determine whether the quadratic function shown below has a minimum or
maximum, then determine the minimum or maximum value of the function.
f(x) = -2(x - 5)(x-7)
Answers
The vertex (3, -16) is the maximum point on our quadratic equation.
Maximum and minimum values of the function:When we compare the given Quadratic function with the general form
ax² +bx +c,
If the value of a is positive then the Quadratic function will have a minimum value, and the graph of the function opens up.
If the value of a is negative then the Quadratic function will have a maximum value, and the graph of the function opens downwards.
Here we have
f(x) = -2(x - 5)(x-7)
f(x) = -2 [x²-7x - 5x + 35 ]
f(x) = -2 [x²-12x + 35 ]
f(x) = -2x² + 12x - 35
Compare f(x) with ax²+ bx + c
=> a = -2, b = 12, and c = - 35
Here,
a = -2 is a negative value then the function f(x) will have maximum value
And the graph of the function opens down.
The formula for the x coordinate of the vertex = -b/2a
The coordinate of x = -(12)/2(-2) = 3
Now substitute x = 3 in f(x) to find y-coordinate
=> f(3) = - 2(3)² +12(3) - 35
=> f(3) = -2(9) + 36 - 35
=> f(3) = - 16

The inequality below represents x, the number of bags she can buy given the spending limit and how much she has already spent on streamers.
Answers
Ling can therefore purchase 0 to 12 bags, but no more is the right decision.
How to calculated the inequality?Ling has been instructed to spend no more than $40.00 on party décor. She has already spent $10.00 on streamers but also plans to purchase bags of balloons. The price of a bag of balloons is $2.50.
Given her spending cap and how much she has already spent on streamers, the inequality 10 + 2.5x ≤ 40 indicates x, the number of bags she can purchase.
Subtracting 10 from both sides of our inequality, let's find x by reversing the inequality.
10 - 10 + 2.5 x ≤ 40 - 10
2.5 x ≤ 30.
We will now divide our inequality by 2.5 on both sides.

How to determine which equation can be used to find the length of the side of the original square?Given that:
When the length of a side of a square is increased by 5, the perimeter of the new square is 60.
Let x represent the length of the side of the original square
when x is increased by 5, you have (x+5)
Perimeter (P) = 4 × length of the side
Thus, 4(x+5) = 60
Therefore, the equation to find the length of the side is 4(x+5) = 60
