1) true2) true3) true4) false5) true.Which statements are correct?
Here we have the quadratic function:
f(x) = (x + 6)*(x + 2)
Let's analyze each statement to see which ones are correct.
1) "The vertex is the maximum value."
True, the leading coefficient is positive, so the parabola opens up, meaning that the vertex is the minimum.
2) " The axis of symmetry is x= -4."
The two roots are x = -6 and x = -2, the axis of symmetry is right between these two values, so it is at x = -4, so this is true.
3) "The domain is all real numbers."
For all quadratic functions, this is true.
4) "The function is increasing over (-0, -4)"
(I don't know what -0 means, the segment (-0, -4) does not exist, so i will take this as false).
5) "The function is negative over (-6, -2)."
This is true, the two roots are at -6 and -2, so between these values the function must be negative.

Triangle A B C is shown. Angle A C B is a right angle. The length of the hypotenuse is 20.
What additional information would be necessary to determine sin(A) without using the Pythagorean theorem? Explain.
The length of AC is needed because it is the side adjacent to ∠A.
The length of AC is needed because it is the side opposite ∠A.
The length of BC is needed because it is the side opposite ∠A.
The length of BC is needed because it is the side adjacent to ∠A.
Answer:
The length of BC is needed because it is the side opposite ∠A.
Step-by-step explanation:
Given the right angles triangle as shown in the attachment, we can get sin(A) without using Pythagoras theorem. Instead we will use SOH CAH TOA trigonometry identity.
According to SOH:
Sin(A) = Opposite/Hypotenuse
Sin(A) = |BC|/|AB|
Opposite side of the triangle is the side facing ∠A.
Based on the formula, we will need to get the opposite side of the triangle which is length BC for us to be able to determine sinA since the hypotenuse is given.
Answer:
Bc is needed because it is opposite of A

The diameter of a cylindrical construction pipe is 6 ft. If the pipe is 30 ft long, what is its volume?
Use the value 3.14 for pi, and round your answer to the nearest whole number.
Be sure to include the correct unit in your answer.
Answer:
848 ft³
Step-by-step explanation:
The volume of a cylinder is given as:
V = pi * r² * h
Where r = radius of the cylinder
h = length of the cylinder.
The diameter of the cylindrical pipe, d = 6 ft
The radius of the cylindrical pipe, r = d/2 = 6 / 2 = 3 ft
The length of the cylindrical pipe, h = 30 ft
The volume of the cylindrical pipe is:
V = 3.14 * 3² * 30
V = 847.8 ft³ = 848 ft³ (to the nearest whole number)
The volume of the cylindrical pipe is 848 ft³.
The volume of a cylindrical construction pipe with a diameter of 6 ft and length of 30 ft can be calculated using the formula for the volume of a cylinder (V = πr²h). Given the specifics, the volume of the pipe is approximately 848 cubic feet.
Explanation:The subject of this question is determining the volume of a cylinder, in this case, a construction pipe. The formula used to calculate the volume of a cylinder is V = πr²h. Here, the diameter of the cylindrical pipe is 6 ft, therefore radius (r) is half of diameter which is 6/2 = 3 ft and the length of the pipe, h, is 30 ft. Substituting r and h into the equation, we have V = 3.14 * (3ft)² * 30ft = 3.14 * 9ft² * 30ft = 847.8 cubic feet. Rounding to the nearest whole number, the volume of the pipe is approximately 848 cubic feet. The unit of volume in this instance is cubic feet, which is a measure of space occupied by a three-dimensional object.

Solve:
3x - 4+2(x-5)= 9x + 8- 2x
Answer:
x = -11
Step-by-step explanation:
3x - 4 + 2(x - 5) = 9x + 8 - 2x
3x - 4 + 2x - 10 = 9x + 8 - 2x
3x + 2x - 9x + 2x = 8 + 10 + 4
- 2x = 22
- x = 22/2
- x = 11
x = - 11
The equation 3x - 4+2(x-5)= 9x + 8- 2x can be solved by first simplifying to 5x - 4 = 7x + 8. After re-arranging, it simplifies to -12 = 2x, and therefore, x = -6.
Explanation:To solve this equation, first simplify and combine like terms on each side of the equation. That gives us: 5x - 4 = 7x + 8. Next, let’s get all the x terms on one side. To do that, we subtract 5x from both sides, which gives us -4 = 2x + 8. Then, subtract 8 from both sides to isolate the 'x', resulting in -12 = 2x. Finally, divide both sides by 2 to find the value of x, which is -6.

A raindrop was 24 meters above the ground, falling straight down at a constant velocity. It took the raindrop 3 seconds to fall half the distance to the ground. What was the raindrops velocity?
Answer:
4 m/s downwards
Step-by-step explanation:
Velocity is given by dividing the distance by time taken to cover the diatance. Therefore, expressed as v=d/t
The distance is given as 24 m but the time given covers only half the distance. Therefore, the distance is 0.5*21=12 m
Time taken is given as 3 s
Substituting 12 m for d and 3 s for t then
V=12/3= 4 m/s
Velocity must have direction component hence velocity is 4 m/s downwards

Answer:
A. electrons will fill orbitals of lower energy first, paring up only after each orbital of the same energy already has one electron
Step-by-step explanation:
The rule states that for a given electron configuration, the lowest energy term is the one with the greatest value of spin multiplicity. This implies that if two or more orbitals of equal energy are available, electrons will occupy them singly before filling them in pairs.
6. Calculate Suppose Cory's
blood pressure is 125 at its
highest point. To return his
blood pressure to normal,
Cory must reduce it by what
percentage? (Show your
work.)
Answer:
Let's suppose that the ideal blood pressure is 100 (the ideal values are between 90 and 110, i am taking the middle value)
If 125 is the 100%, and we want to go to 100, then we need to decrease by:
125 - 100 = 25
now, to calculate the percentage that represents the 25, we need to calculate:
(25/125)*100% = 20%
So to reduce his blood pressure to normal, he must reduce it by 20%
To find out by what percentage Cory must reduce his blood pressure to normal, subtract the normal from Cory's blood pressure, divide the result by Cory's initial blood pressure, and then multiply by 100. For instance, if normal blood pressure is 120, Cory must reduce his blood pressure by approximately 4%.
Explanation:To calculate the percentage that Cory needs to reduce his blood pressure, we first need to know the normal blood pressure level. For example, if the normal blood pressure is considered to be 120, then we can proceed as follows:
First find the difference between Cory's actual blood pressure and the normal blood pressure. In this case, it would be 125 - 120 = 5. Then, divide this difference by the initial (Cory's) blood pressure, which is 5 / 125 = 0.04. Multiply the result by 100 to get it in percentage terms: 0.04 * 100 = 4%.
So, Cory would need to reduce his blood pressure by approximately 4% to return to a normal level, assuming normal blood pressure is 120.

(AKS 16/17): You have earned $200 doing chores around the house. How long will it
take to triple your money if you keep it in an account earning 4.25% compounded
continuously? Use the formula:
Answer:
It will take 26 years
Step-by-step explanation:
In this question, we are tasked with calculating the time it will take for an amount of money earned to be tripled if compounded continuously.
To calculate this amount of time, we are going to use the formula for compound interest. Mathematically, for an interest compounded, the amount is as follows;
[tex]A = P(1 + r/n)^{nt}[/tex]
Where;
A is the amount at the end of compounding; which is 3 times the original amount = 3 × $200 = $600
P is the initial amount = $200
r is the rate of compounding = 4.25% = 4.25/100 = 0.0425
n is the number of times in which the amount is compounded annually, we take this as 1
t is the time taken to reach the amount
We substitute these values in the equation;
600 = 200(1 + 0.0425/1)^t
Divide through by 200
3 = (1.0425)^t
Take the logarithm of both sides
log 3 = log(1.0425)^t
log 3 = tlog 1.0425
t = log 3/log1.0425
t = 26.4 which is approximately 26 years

Total Surface Area?
Answer: Total Surface Area
Step-by-step explanation:
Hi, to calculate the amount of cardboard needed to create a cereal box we have to calculate the total surface area.
The volume is used to calculate the amount of cereal that the box can contain, and the lateral surface area will not include all the cardboard needed for the complete box.
Feel free to ask for more if needed or if you did not understand something.
To calculate the amount of cardboard needed to create a cereal box, we would be solving for the Total Surface Area. This is the sum of the areas of all the faces (or sides) of the box.
Explanation:When we talk about the amount of cardboard needed to create a cereal box, we are interested in determining the
Total Surface Area
of the box. The surface area is the measure of the total amount of material needed to cover the surface of an object. If we're considering a cereal box, which is a three-dimensional rectangular prism, its total surface area is calculated by summing up the areas of all its six faces (top and bottom, front and back, left and right). Specifically, the formula for the total surface area of a box or rectangular prism is 2lw + 2lh + 2wh where l is the length, w is the width, and h is the height.

14 girls and 17 boys attend a party. 6 girls and 7 boys brought balloons. What is the probability of randomly choosing a girl or someone who did not bring a balloon
Answer:
[tex]\dfrac{24}{31}[/tex]
Step-by-step explanation:
Given information:
Total number of girls = 14
Total number of boys = 17
Total number of peoples = 14 + 17 = 31
6 girls and 7 boys brought balloons.
Let A and B are two events, such that
A = Choosing a girl
B = Choosing someone who did not bring a balloon.
[tex]A\cup B[/tex] = Choosing girl or someone who did not bring a balloon.
[tex]n(S)=31,n(A)=14,n(B)=18,n(A\cup B)=14+10=24[/tex]
The probability of randomly choosing a girl or someone who did not bring a balloon is
[tex]P=\dfrac{n(A\cup B)}{n(S)}[/tex]
[tex]P=\dfrac{24}{31}[/tex]
Therefore, the required probability is [tex]\dfrac{24}{31}[/tex].
The probability of randomly choosing a girl or someone who did not bring a balloon at a party is 24 out of 31, which simplifies to the fraction 24/31.
To solve this problem, we can use the concept of probability and the addition rule since the events are not mutually exclusive.
First, let's define the total number of people at the party: 14 girls + 17 boys = 31 people.
Next, we look at the number of girls who brought balloons, which is 6, meaning there are 14 - 6 = 8 girls who did not bring balloons.
Similarly, 17 boys - 7 boys who brought balloons = 10 boys who did not bring balloons.
Now, let's calculate the number of ways to choose a girl or someone who did not bring a balloon. For the girls, it's simply the total number of girls, 14. For those who did not bring balloons, we need to add the number of girls who did not bring balloons to the number of boys who did not bring balloons: 8 girls + 10 boys = 18 people who did not bring a balloon.
Combining these, the event of choosing a girl overlaps with the event of choosing someone who did not bring a balloon, so we have to subtract the number of girls who did not bring a balloon once to avoid double-counting: 14 + 18 - 8 = 24.
Thus, the probability is: 24 out of 31, which we can write as 24/31.

0.0025 as a square root
Answer:
Accoridng to your question we have to find the square root of 0.0025
However students face some problem in finding square roots of number in decimal but it is too easy to find .
√0.0025
0.05 is the square root of 0.0025
after decimal there are two zero and by square root there will be one zero and 25 is the square root of 5 .
so thus we find the square root amd the correct answer is 0.05
The square root of 0.0025 is 0.05, which follows the rule that the square root of a decimal results in half the number of decimal places in the square root, compared to the original number.
Explanation:The student has asked to find the square root of 0.0025. When expressed as a square root, the number 0.0025 is equal to 0.05 because (0.05 * 0.05 = 0.0025). This can be understood by recognizing that the decimal places need to be managed correctly when finding the square root of a decimal. For instance, the square root of 25 is 5, and since 0.0025 has four decimal places, the square root will have half as many decimal places, resulting in 0.05. This concept is further emphasized by using fractional powers, such as re-expressing a number squared (x²) as the square root ( √x ), where x to the power of 2 is the same as x to the power of 1/2.

Given LaTeX: f\left(x\right)=x^{^3}-3x+4f ( x ) = x 3 − 3 x + 4, determine the intervals where the function is increasing and where it is decreasing.
Answer:
Increasing: [tex]x<-1[/tex] and [tex]x>1[/tex].
Decreasing: [tex]-1<x<1[/tex]
Step-by-step explanation:
We have been given a function [tex]f(x)=x^3-3x+4[/tex]. We are asked to determine the intervals, where the function is increasing and where it is decreasing.
First of all, we will find critical points of our given function by equating derivative of our given function to 0.
Let us find derivative of our given function.
[tex]f'(x)=\frac{d}{dx}(x^3)-\frac{d}{dx}(3x)+\frac{d}{dx}(4)[/tex]
[tex]f'(x)=3x^{3-1}-3+0[/tex]
[tex]f'(x)=3x^{2}-3[/tex]
Let us equate derivative with 0 as find critical points as:
[tex]0=3x^{2}-3[/tex]
[tex]3x^{2}=3[/tex]
Divide both sides by 3:
[tex]x^{2}=1[/tex]
Now we will take square-root of both sides as:
[tex]\sqrt{x^{2}}=\pm\sqrt{1}[/tex]
[tex]x=\pm 1[/tex]
[tex]x=-1,1[/tex]
We know that these critical points will divide number line into three intervals. One from negative infinity to -1, 2nd -1 to 1 and 3rd 1 to positive infinity.
Now we will check one number from each interval. If derivative of the point is greater than 0, then function is increasing, if derivative of the point is less than 0, then function is decreasing.
We will check -2 from our 1st interval.
[tex]f'(-2)=3(-2)^{2}-3=3(4)-3=12-3=9[/tex]
Since 9 is greater than 0, therefore, function is increasing on interval [tex](-\infty, -1) \text{ or } x<-1[/tex].
Now we will check 0 for 2nd interval.
[tex]f'(0)=3(0)^{2}-3=0-3=-3[/tex]
Since -3 is less than 0, therefore, function is decreasing on interval [tex](-1,1) \text{ or } -1<x<1[/tex].
We will check 2 from our 3rd interval.
[tex]f'(2)=3(2)^{2}-3=3(4)-3=12-3=9[/tex]
Since 9 is greater than 0, therefore, function is increasing on interval [tex](1,\infty) \text{ or } x>1[/tex].
Two of the steps in the derivation of the quadratic formula are shown below.
Step 6: StartFraction b squared minus 4 a c Over 4 a squared EndFraction = (x + StartFraction b Over 2 a EndFraction) squared
Step 7: StartFraction plus or minus StartRoot b squared minus 4 a c EndRoot Over 1 a EndFraction = x + StartFraction b Over 2 a EndFraction
Which operation is performed in the derivation of the quadratic formula moving from Step 6 to Step 7?
subtracting StartFraction b Over 2 a EndFraction from both sides of the equation
squaring both sides of the equation
taking the square root of both sides of the equation
taking the square root of the discriminant

I have 420 apples & its 35% of what I needed how many apples do I need
Answer:
1200 apples.
Step-by-step explanation:
The way I thought about this was, you need to figure out how many apples per percent. Thus, I divided 420 by 35, which gave me 12.
We have deduced that every percent = 12 apples.
Multiply 12 by 100 (apples per percent x total percentage)
12 x 100 = 1200
x + 3/3+x=?

Question
Segments AC and BD are diameters of circle Q.
a. Find the measure of arc AB
b. Find the measure of arc AD
Answer:
Arc AB = 80°
Arc AD= 100°
Step-by-step explanation:
Arc AB
Since AC is the diameter, it would be 180°, and since arc BC is given (100°), arc AB would be 80°
Arc AD
Since BD is a diameter, it would also be 180°. Arc ED is given and previously you found arc AB. So subtract 50 and 80 from 180 and you'll get 50° for arc AE. Add that with arc ED and you'll get 100°
A ratio of the number of items within a defined unit of area measures
Answer:
Density
Step-by-step explanation:
Density is the number of items per unit area. It is gotten by dividing the number of items by the area it occupies. It measures the compactness of an item in a given area. The higher the density, the more compact items are per unit area and the lesser the density, the less compact items are per unit area. It is measured in items/m²
