What are the solutions to the quadratic equation below x^2+20x+100=7
First you must have the quadratic equal to zero. In order to do this you must subtract 7 to both sides
x^2 + 20x + (100 - 7) = 7 - 7
x^2 + 20x + 93 = 0
Now you must find two numbers who's sum equals 20 and their multiplication equal 93

A ball is dropped from the top of a building that is 1,000 feet high. Its height, in feet, as a function of the time, x, in seconds, after the ball was dropped, is given by the following equation, ƒ(x) = 1,000 - 16x 2. Which set of numbers is appropriate as the domain for this function?
Real numbers from 0 to sqrt(1000/16) = 0 to 2.5sqrt(10).
Before 0, it hadn't been dropped. After 2.5sqrt(10), it has hit the ground and stopped falling.Positive Real Numbers. This includes fractions of seconds, the other two don't.
The appropriate domain for the function describing the height of a ball dropped from a 1,000 feet high building as a function of time is 0 <= x <= 25 seconds, indicating the ball's descent time until it hits the ground.
The student has asked about the appropriate domain for a function describing a ball dropped from a height of 1,000 feet, given by the equation f(x) = 1,000 - 16x². To find the domain, we need to understand when the ball hits the ground, marking the end of its free fall and the function's practical use.
The height (f(x)) becomes 0 when the ball reaches the ground. Setting the equation to zero gives us 0 = 1,000 - 16x². Solving for x, we find x = 25 seconds. This means the ball will hit the ground after 25 seconds, indicating the end of its descent and the maximum value of x in the domain. Therefore, the appropriate domain for this function, representing the time from when the ball was dropped until it hits the ground, is 0 ≤ x ≤ 25 seconds.

A rectangle has perimeter of 20, if the length and width are halved. What is the new perimeter ?
Answer:
10
Step-by-step explanation:
The perimeter will also be halved: (1/2)(20) = 10.
Example: a rectangle of length 14 ft and width 8 ft has perimeter P = 2(14 ft) + 2(8 ft), or 28 ft + 16 ft = 44 ft.
If we halve the length and width, we get 7 ft and 4 ft, and the P is
2(7 ft) + 2(4 ft) = 14 ft + 8 ft = 22 ft, which is half of the original perimeter 44.
An engineer is designing a roller coaster. The tallest peak is 310 feet high.
The roller coaster travels 155 horizontal feet as it descends the hill.
What is the slope of the hill?
The answer is:
The slope of the hill is equal to 2.
Why?To solve the problem, we need to remember that the slope of a line, is the rate of increase or decrease of the line.
From the statement we know that the tallest peak of the roller coaster is 310 feet (y), while the roller coaster travels 155 horizontal feet (x), so, calculating we have:
[tex]Slope=\frac{height}{base}=\frac{y}{x}[/tex]
Then, substituting the given information and calculating, we have:
[tex]Slope=\frac{310ft}{155ft}=2[/tex]
We have that the slope of the hill is equal to 2.

ANSWER
The next term in the given geometric sequence is 4.
EXPLANATION
We want to find the next term in the geometric sequence
32,16,8,
We can observe that there is a common ratio of
[tex] \frac{16}{32} = \frac{1}{2} [/tex]
This implies that, we obtain the subsequent terms by multiplying the previous terms by ½.
To obtain the next term after 8, we multiply 8 by half to get.
[tex] 8 \times \frac{1}{2} = 4[/tex]
Therefore the next term is 4.
which expression is 444 times as large as the expression 34 -15
A
4 x 34 - 15
B
4 x (34 - 15)
C
(4 x 34) - 15
Final answer:
The expression that is 444 times as large as the expression 34 - 15 is (4 x 34) - 15.
Explanation:
To find the expression that is 444 times as large as the expression 34 - 15, we need to multiply the expression by 444. The correct expression is option C, which is (4 x 34) - 15. Let's break it down:
First, we perform the multiplication: 4 x 34 = 136.
Then, we subtract 15 from the result: 136 - 15 = 121.
Therefore, the expression (4 x 34) - 15 is 444 times as large as the expression 34 - 15.
Eight more than the product of a number and 4 is equal to 6
Answer:8>4n=6 or 8>4+n=6
Step-by-step explanation:
Let's solve the equation step by step. The problem statement can be translated into a mathematical equation:
"Eight more than the product of a number and 4 is equal to 6."
Let x be the number we are looking for. When the problem says "the product of a number and 4," we can express this as 4 * x or 4x. The phrase "eight more than" implies we are to add 8 to the product of the number and 4, making the expression 4x + 8. According to the statement, this expression is equal to 6. Thus, we write the equation as:
4x + 8 = 6
To find the value of x, we will follow these steps:
1. Subtract 8 from both sides of the equation to isolate the term with x on one side.
4x + 8 - 8 = 6 - 8
This simplifies to:
4x = -2
2. Divide both sides of the equation by 4 to solve for x.
4x / 4 = -2 / 4
This simplifies to:
x = -1/2
So the number we were looking for, represented as x, is -1/2.

In a standard deck of cards there are four suits: spades, clubs, hearts, and diamonds. Each suit has one each of 13 cards: ace, king, queen, jack, 2, 3, 4, 5, 6, 7, 8, 9, and 10.
If event A is choosing a king, event B is choosing a heart, and event C is choosing a jack, which Venn diagram could represent this description?
Answer:
The answer would be graph A.
Step-by-step explanation:
Since the cards all belong to four suites, the king can be a heart as well as the jack, but they cannot be the same card. So the choice is graph A.
A Venn diagram displaying events A, B, and C, with overlaps representing the king of hearts (A intersect B) and the jack of hearts (B intersect C), correctly describes the description given.
The Venn diagram that represents the description given should consist of three overlapping circles, one for each event: choosing a king (event A), choosing a heart (event B), and choosing a jack (event C).
Since there is one king and one jack in the hearts suit, the events are not mutually exclusive and the intersections between the circles will represent these possibilities.
There will be an overlap between events A and B, which represents the king of hearts, and an overlap between events B and C, which represents the jack of hearts. However, there will not be an overlap between events A and C since a card cannot be a king and a jack simultaneously.

What is the missing measure on the small rectangle?
Answer:
4 inches
Step-by-step explanation:
If you divide 18 by 6, the answer is three, so it is scaled down 3x.
So, you have to divide 12 by 3, and the answer is 4.
Answer: 4 Inches
Step-by-step explanation: The rectangle on the left shows that the length is 18 inches and the height is 12 inches. Now, to find the height on the right, First we must realize what changed has been made from the left to the right. We know that our length has decreased to 6 inches from 18. 18 can be divided by 3 and that will give us the quotient of 6. Now, we must divide our height on our original rectangle by 3 as well. Once we divide, our new height of our rectangle also known as X will be 4 Inches Long.

H - height
We have r = 6cm and H = 8cm. Substitute:
[tex]V=\pi(6^2)(8)=\pi(36)(8)=288\pi\ cm^3[/tex]
[tex]\pi\approx3.14\to V\approx(288)(3.14)=904.32\ cm^3[/tex]
Answer:
904.32 cm³
Step-by-step explanation:
The volume (V) of a cylinder is calculated using the formula
V = πr²h ( r is the radius of the base and h the height )
here r = 6 and h = 8, so
V = 3.14 × 6² × 8
= 3.14 × 36 × 8 ≈ 904.32 cm³

which of the following is not equal to cos(-576)
A.cos 216
B. -cos(-36)
C. sin 126
d. -sin 54
e. cos 144
ANSWER
C. sin 126°
EXPLANATION
-576° is coterminal with ±216,±144.
Therefore
cos (-576°)=cos(±216°)=cos(±144°)
The principal angle for -576° is 36° .
Since the terminal side of -576° is in the second quadrant and the cosine ratio is negative in the second quadrant,
cos (-576°)=-cos (±36°)
Also from complementary angles
cos (-576°)=-cos (36°)=-sin (90-36)=-sin(54°)

Final answer:
The probabilities are matched as follows: A-24%, B-76%, C-19%, and D-25%. These are calculated based on the total number of balls of each color and the fraction that are labeled to win a prize.
Explanation:
The question provides a scenario where there are 24 yellow balls and 76 red balls in a box, and one-fourth of each color are labeled "Win a prize." We are asked to match descriptions of probabilities with their corresponding percent values.
A: Probability that a randomly selected ball labeled "Win a prize" is yellow = (1/4 * 24) / ((1/4 * 24) + (1/4 * 76)) * 100 = 6 / (6 + 19) * 100 = 24%.
B: Probability that a randomly selected ball labeled "Win a prize" is red = (1/4 * 76) / ((1/4 * 24) + (1/4 * 76)) * 100 = 19 / (6 + 19) * 100 = 76%.
C: Probability that a randomly selected ball is labeled "Win a prize" and is red = (1/4 * 76) / 100 = 19%.
D: Probability that a randomly selected yellow ball is labeled "Win a prize" = (1/4 * 24) / 24 * 100 = 25%.
