Raul is performing an experiment. He pours water into a glass and measures the temperature of the water at 72.3°F. Then he adds a few ice cubes to the glass of water. He measures the temperature of the water again and finds that it has changed by -39.1°F.
Complete the steps below to learn more about the temperature change of the water.
Part A
Write an expression that represents the temperature (in degrees Fahrenheit) of the water after Raul added the ice cubes. Write the expression as the sum of two numbers.
Answers
The expression that represents the temperature of water after Raul added the ice cubes would be = x°F = 72.3°F + 39.1°F
What is temperature?Temperature is defined as the quantity that is used to measure the degree of hotness or coldness of a body which can be measured in degree fahrenheit or degree celsius.
The original temperature of the water in the glass before the addition of ice cube = 72.3 °F.
The temperature of water after the addition of ice cube = -39.1°F.
The temperature of ice cube = x°F
Therefore the expression that would represent the temperature of water after addition of ice cube =
-39.1°F = x°F - 72.3°F
make x°F the subject of formula;
x°F = 72.3°F + 39.1°F

PLEASE HELP !!!!!!!
Answers
Answer:
x ≈ 4.5
Step-by-step explanation:
Let y represent the hypotenuse of the smaller triangle. The Pythagorean theorem tells us the sum of the squares of the legs is equal to the square of the hypotenuse. This lets us write two equations:
1² +2² = y²
y² +x² = 5²
Using the first equation to substitute for y² in the second equation, we get ...
1² +2² +x² = 5²
1 + 4 + x² = 25 . . . . compute the squares
x² = 25 -5 = 20 . . . subtract 5
x = √20 ≈ 4.472 . . . . take the square root

A couple plans to save for their child's college education. What principal must be deposited by the parents when their child is born in order to have $44,000 when the child reaches the age of 18? Assume the money earns 5% interest, compounded monthly.
Answers
Answer:
$17,922.55
Step-by-step explanation:
The future value of a one-time investment is calculated using the formula ...
FV = P(1 +r/n)^(nt)
where principal P is invested at annual rate r compounded n times per year for t years.
__
You have FV = 44000, r = 0.05, n = 12, t = 18, and you want to find P.
44000 = P(1 +0.05/12)^(12·18) ≈ 2.455008P
P = 44000/2.455008 = 17,922.55
The couple must deposit $17,922.55 in order to have $44,000 in 18 years.

An open circle is at 5 and a bold line starts at 5 and is pointing to the right. A number line from negative 3 to 3 in increments of 1. An open circle is at negative 5 and a bold line starts at negative 5 and is pointing to the left.
Answers
An open circle at 5 and a bold line starting at 5 and pointing to the right (>) is the correct representations of the inequality
How to identify the correct representations of the inequality?An inequality compares two values, showing if one is less than, greater than, or simply not equal to another value e.g 5 < 6, x ≥ 2, etc.
Given: the inequality –3(2x – 5) < 5(2 – x)
First, we have to solve for x in the inequality
–3(2x – 5) < 5(2 – x)
Clear the parenthesis:
-6x + 15 < 10 - 5x
Collect like terms:
-6x + 5x < 10 - 15
-x < -5
Divide both sides by -1:
x > 5 ( Note: Dividing both sides by -1 will change the < to > )
This is what will determine our answer
Since our answer is x > 5. An open circle will be at 5 and a bold line starts at 5 and is pointing to the right (>)
Therefore, the correct representations of the inequality is an open circle is at 5 and a bold line starts at 5 and is pointing to the right

Let's roll two dice and find the probability of rolling a certain sum. Is this a simple or compound event?
Two dice - Red and Blue
Recall that a simple event has one and only one outcome of interest. In this example, we are rolling two dice, but we are only interested in one outcome, the sum of the two dice. This is a simple event.
What is the probability of:
Rolling a sum of 1?
Rolling a sum of 3?
Rolling a sum of 12?
Rolling a sum of 7?
Since we are rolling a pair of dice and looking for the sum, the sample space is a little more complicated than rolling one die. The chart below will help us determine the possible outcomes. The top row indicates the numbers on the sides of the blue die and the first column represents the number on the sides of the red die. The white area indicates the sum of the numbers in the row and column.

Which of the following is true for the function f(x)=2cos(x2)
a. The period is π
b. The period is π2
c. The period is 2π
d. The period is 4π
e. The period is 2
Answers
Answer:
c. The period is 2π
Step-by-step explanation:
The period of a function is the smallest value of $p$ for which\( f(x+p) = f(x)\) for all x.
For the function f(x) = 2cos(x^2), we can see that f(x+2π) = f(x) for all x.
This is because the cosine function has a period of 2π. Therefore, the period of f(x) = 2cos(x^2) is \(\boxed{2\pi}\)

Step-by-step explanation:
3^x +1 = f(X)
2x-4 = g(x)
find f(2)-g(-1)
we substitute in function f(X) by value (2), and in function g(X) by value (-1)
1. 3^x +1 becomes 3^2+1 =9+1=10
2. 2(-1)-4= -2-4=-6
then f(2)-g(-1)

Mrs. Silva owns a cake shop and she is working on two wedding cakes this week. The first cake consists of 3 small tiers and 5 medium tiers, which will serve a total of 291 guests. The second one includes 1 small tier and 5 medium tiers, which is enough servings for 247 guests. How many guests does each size of tier serve?
Answers
Answer:
small = 22 ; medium = 45
Step-by-step explanation:
3s + 5m = 291
s + 5m = 247
s = -5m + 247
3(-5m + 247) + 5m = 291
-15m + 741 + 5m = 291
- 10m = 291 - 741
- 10m = - 450
m = -450/ -10
m = 45
s = -5(45) + 247
s = -225 + 247
s = 22

a quadratic function with a constant difference of 2
an exponential function with growth factors of 1, then 2, then 4, ..
Answers
The best description of the graph is "a quadratic function with a constant difference of 2."
A quadratic function is a function of the form f(x) = ax^2 + bx + c, where a, b, and c are constants. In a quadratic function, the graph forms a parabola.
In the given graph, if the differences between consecutive points on the graph are constant and equal to 2, it indicates a constant difference in the y-values (vertical direction) as the x-values (horizontal direction) increase. This is a characteristic of a quadratic function.
On the other hand, an exponential function with a growth factor of 2 would result in a graph that increases at an increasing rate, where the y-values grow exponentially as the x-values increase. This is not observed in the given graph.
Therefore, based on the information provided, the graph best represents a quadratic function with a constant difference of 2.

Drag and drop expressions into the function to correctly define S(a).
Answers
The function that correctly defines S(x) is S(x) = 5x - 2(20 - x) + 20
How to determine the function that correctly defines S(x)We have the following definitions in the question
Correct answers = xTotal questions = 20Points for correct answers = 5Points for incorrect answers = -2Bonus for finishing in one hour or less = 20If the total questions is 20, then
Incorrect answers = 20 - x
So, the points gained/lost are
Gained = 5 * x = 5x
Lost = -2 * (20 - x) = -2(20 - x)
Bonus = 20
Add the above points to get the function S(x)
S(x) = 5x - 2(20 - x) + 20
Hence, the definition is S(x) = 5x - 2(20 - x) + 20

Given the Right Triangle EFG, you know that:
\(\begin{gathered} EF=4 \\ EG=12 \end{gathered}\)By definition:
\(sin\theta=\frac{opposite}{hypotenuse}\)Since, in this case:
\(\theta=G\)You can identify that:
\(\begin{gathered} opposite=EF=4 \\ hypotenuse=FG \end{gathered}\)In order to find the hypotenuse of the Right Triangle, you need to use the Pythagorean Theorem, which states that:
\(c=\sqrt{a^2+b^2}\)Where "c" is the hypotenuse, and "a" and "b" are the legs of the Right Triangle.
You can set up that:
\(\begin{gathered} c=FG \\ a=EG=12 \\ b=EF=4 \end{gathered}\)Therefore:
\(FG=\sqrt{12^2+4^2}=4\sqrt{10}\)Now you can determine that:
\(sinG=\frac{4}{4\sqrt{10}}\)Simplify:
\(sinG=\frac{1}{\sqrt{10}}\)You can multiply the numerator and the denominator by:
\(\sqrt{10}\)In order to Rationalize the denominator:
\(sinG=\frac{1\cdot\sqrt{10}}{\sqrt{10}\cdot\sqrt{10}}\)\(sinG=\frac{1\cdot\sqrt{10}}{(\sqrt{10})^2}\)\(sinG=\frac{\sqrt{10}}{10}\)Hence, the answer is: Option A.
