Identify the open intervals on which the function is increasing or decreasing. (Enter your answers using interval notation.) f(x) = sin(x) + 9 0 < x < 2Ï€ increasing decreasing
Answers
The function is increasing on the open interval (0, 2Ï€) and decreasing on the open interval (-2Ï€, 0).
The derivative of a function tells us the slope of the function at any given point, and the sign of the derivative tells us whether the function is increasing or decreasing at that point. If the derivative is positive, the function is increasing at that point, and if the derivative is negative, the function is decreasing at that point.
The function f(x) = sin(x) + 9 is increasing on the interval (0, 2π) because the derivative of sin(x) is positive on this interval. The derivative of sin(x) is cos(x), which is positive for all values of x except for multiples of π.

Find the area of the shaded part.
19) The area of the shaded part is ___in²
Answers
The area of the shaded part of the rectangle given the total rectangle and unshaded part of the rectangle is 440 in²
What is the area of the shaded part?Total rectangle:
Length of the rectangle = 30 in
Width of the rectangle = 20 in
Area of total rectangle = Length of the rectangle × Width of the rectangle
= 30 in × 20 in
= 600 in²
Unshaded rectangle:
Length of the rectangle = 16 in
Width of the rectangle = 10 in
Area of unshaded rectangle = Length of the rectangle × Width of the rectangle
= 16 in × 10 in
= 160 in²
Area of the shaded part = Area of total rectangle - Area of unshaded rectangle
= 600 in² - 160 in²

Which of these events is not mutually exclusive?
A) the chance that you will get a heads or tails when you flip a coin once.
B) the chance that you will only study for the test alone or with a friend.
C) the chance that you will meet your friends for pizza or at a chinese restaurant for dinner today at 6.
D) the chance that you will answer the ringing phone or take a walk.
Answers
The chance that you will get a heads or tails when you flip a coin once (option A) is not mutually exclusive.
Mutually exclusive events are events that cannot occur at the same time, or that do not have any overlap. In the case of flipping a coin, the possibility of getting a head and the possibility of getting tails are independent of each other, and both can occur simultaneously. Therefore, the chance that you will get heads or tails when you flip a coin once is not mutually exclusive.
On the other hand, the other events listed (B, C, and D) are mutually exclusive. The chance that you will only study for the test alone or with a friend cannot occur simultaneously, as you can either study alone or with a friend, but not both. Similarly, the chance that you will meet your friends for pizza or at a Chinese restaurant for dinner today at 6 cannot occur at the same time, as you can either go to the pizza place or the Chinese restaurant, but not both. And the chance that you will answer the ringing phone or take a walk cannot occur simultaneously, as you can either answer the phone or take a walk, but not both.

Mutually exclusive events are those events that do not occur at the same time.
For example, when a coin is tossed then the result will be either head or tail, but we cannot get both the results. Such events are also called disjoint events since they do not happen simultaneously.

How do you change 5/8 to an equivalent fraction with a denominator of 100
Answers
We can multiply both the numerator and denominator by 12.5 to get the equivalent fraction:
5/8 = 62.5/100
How to find the equivalent fraction?We want to rewrite 5/8 as an equivalent fraction with a denominator of 100.
Remember that if we multiply both the numerator and denominator of a fraction by the same number, then we will get an equivalent fraction.
So if that number is x, we can write:
5/8 = (5*x)/(8*x)
First, we want a denominator of 100, then the value of x must be such that:
8*x = 100
x = 100/8
x = 12.5
Then the equivalent fraction is:
(5*12.5/8*12.5) = 62.5/100

A paper has an area of 598 square centimeters. What is the paper's area in square inches? Use the following conversion: 1 square inch is 6.5 square centimeters.
Answers
Answer:
[tex]92.0 in.^{2}[/tex]
Step-by-step explanation:
The prompt said to use the conversion 1 square inch to 6.5 square centimeters.Keeping this in mind, we will divide the value of 598 square centimeters by a ratio of [tex]6.5cm^{2} : 1 in.^{2}[/tex].To do this, we will use the following equation: [tex](A_{I}) = \frac{598}{6.5} \frac{cm^{2}}{cm^{2} /in.^{2} }[/tex]
where [tex]A_{I}[/tex] represents the area of the paper in inches.\
Next, divide the numerical value of 598 by 6.5, receiving the quotient [tex]\frac{598}{6.5} \frac{cm}{cm/in.^{2} } = 92.0 \frac{cm}{cm/in.^{2} }[/tex].
Now we can adjust to find the proper units.Cancel the [tex]cm^{2}[/tex] (square centimeters unit) existing in both the numerator and the denominator, thereby leaving [tex]92.0 \frac{1}{1/in.^{2} }[/tex].
Finally, since the inverse of the inverse of a number is that same number itself ([tex]\frac{1}{1/b} = b[/tex]), we rewrite the measuring units of this quotient as [tex]92.0 in.^{2}[/tex].
Now our answer is clean and finalized for submission.
An ideal gas occupies a volume of 0.50 liter (L) at a pressure of 0.20 atmosphere. What volume will the gas occupy at 0.40
atmosphere if the temperature remains constant?
A) 0.25 L
B) 0.50 L
C) I L
D) 2L
Correct answer is 0.25, but please show the work
Answers
Answer:
To find the volume of the gas at a pressure of 0.40 atm if the temperature is held constant, we can use the ideal gas law:
PV = nRT
Where P is the pressure of the gas, V is the volume of the gas, n is the number of moles of gas, R is the ideal gas constant, and T is the temperature of the gas.
Since the number of moles and the temperature of the gas are constant, we can rearrange the equation to solve for V:
V = (nRT)/P
Plugging in the given values, we have:
V = (nRT)/P = (nRT)/(0.40 atm)
We know that the original volume of the gas was 0.50 L, so the new volume will be:
V = (0.50 L)(0.20 atm)/(0.40 atm) = 0.50 L / 2 = 0.25 L
So the volume of the gas at a pressure of 0.40 atm will be 0.25 L. The correct answer is A) 0.25 L.
Answer:
A) 0.25 L
Step-by-step explanation:
Use Boyle's Law:
[tex] P_1V_1 = P_2V_2 [/tex]
[tex] 0.20~atm \times 0.5~L = 0.40~atm \times V_2 [/tex]
[tex] V_2 = \dfrac{0.20~atm \times 0.5~L}{0.40~atm} [/tex]
[tex] V_2 = 0.25~L [/tex]

B)Calculate the probability of children with both cystic fibrosis and polydactyly when parents are each heterozygous for both genes.
C)Calculate the probability of each of four children having cystic fibrosis if the parents are both heterozygous.
D)Calculate the probability of a child having only sickle-cell anemia or cystic fibrosis if each parent is each heterozygous for both traits.
Answers
If probability each parent is heterozygous for both features, determine the likelihood that a child will only have cystic fibrosis or sickle-cell anaemia.
P(Sickle-cell Anemia)
= 0.25
P(Cystic Fibrosis)
= 0.25
P(Sickle-cell Anemia or Cystic Fibrosis) = P(Sickle-cell Anemia) + P(Cystic Fibrosis)
P(Sickle-cell Anemia or Cystic Fibrosis)
= 0.25 + 0.25
P(Sickle-cell Anemia or Cystic Fibrosis)
= 0.5
The likelihood that a child will have either cystic fibrosis or sickle-cell anaemia is 0.5 or 50%. This is because both parents are heterozygous for both features. This means that each parent has a 25% chance of passing on either one of the conditions to their child. The probability of having either one of the conditions is the sum of the individual probabilities, which is 0.25 + 0.25 = 0.5 or 50%.

Answers
Given a rectangle of which its length is nine more than triple the width. The width is _10_inches. The length is 39 inches.
Let:
l = length of the rectangle
w = width of the rectangle
"The length of a rectangle is nine more than triple the width" can be translated as:
l = 9 + 3w
perimeter = 2 l + 2w
Substitute perimeter = 98 and l = 9 + 3w into the perimeter equation:
98 = 2 x (9 + 3w) + 2w
98 = 18 + 8w
8w = 98 - 18
8w = 80
w = 80/8 = 10 inch.
Substitute w = 10 into the length equation:
l = 9 + 3w

The length of the shadow when the sun altitude is 60 degrees is 8.7 feet.
How to find the side of a right triangle?The clock tower is 15 feet tall. The length of the shadow when the sun is at an altitude of 60 degrees can be calculated as follows:
This situation forms a right angle triangle.
Hence, using trigonometric ratios,
tan 60 = opposite / adjacent
where
opposite side = 15 feet
adjacent side = x
tan 60 = 15 / x
cross multiply
x tan 60° = 15
divide both sides by tan 60
x = 15 / tan 60
x = 15 / 1.73205080757
