a square garden plot has an area of 24 ft2. a. find the length of each side in simplest radical form. b. calculate the length of each side to the nearest tenth of a foot.
The area of a square is equal to the side squared.
[tex]s^{2} = A[/tex]
We can plug in 24 for A and then take the square root of each side to
find s.
[tex]s^{2} = 24[/tex]
[tex]s = \sqrt{24}[/tex]
We can simplify √24.
The prime factorization of 24 is 2 x 2 x 2 x 3.
Since we have 2 x 2 inside the radical we can simplify to have 2
outside the racial.
[tex]\sqrt{24} = \sqrt{4*6} = 2 \sqrt{6}[/tex]
We can then use a calculator to find an approximate decimal value
2√6.
(You could technically calculate it by hend using the Babylonian
method, I don't think youre expectited to do that, though)

reference the right triangle shown below to write the quantity as a fraction in lowest terms
tan P
Answer:
A right angled triangle is a triangle where one of the internal angles is 90°.
Consider the general right angle triangle, in figure 1 below, with angle β and sides labeled as shown below
Right-Angle-Triangle
The sides are labeled with respect to the angle β, so that the nearest side is called the adjacent side, the side that is directly opposite is called the opposite side while the longest side is called the hypotenuse.
Therefore, given any angle in a triangle, it should be easy to identify the adjacent, the opposite side and the hypotenuse.
Example
Reference to the figure below.
Example1
1. Identify the right angle triangles in the above diagram.
Solution: A right angled triangle is a triangle where one of the internal angles is 90°. Such triangles are ABC, ABN, DAC and DNC.
2. Identify the adjacent sides to angles θ, α, β and µ.
Solution:
Angle θ is in triangle DAC. The angle is nearer to line AC hence, it is the adjacent line.
Angle α is in triangle ABN. The angle is nearer to line AB hence, it is the adjacent line.
Angle β is in triangle DNC. The angle is nearer to line DC hence, it is the adjacent line.
Angle µ is in triangle ABC. The angle is nearer to line AB hence, it is the adjacent line.
3. Identify the opposite sides to angles θ, α, β and µ.
Solution:
Angle θ is in triangle DAC. The angle is opposite to line DC hence, it is the opposite line.
Angle α is in triangle ABN. The angle is opposite to line AN hence, it is the opposite line.
Angle β is in triangle DNC. The angle is opposite to line CN hence, it is the opposite line.
Angle µ is in triangle ABC. The angle is opposite to line AC hence, it is the opposite line.
4. Identify hypotenuse with respect to angles θ, α, β and µ.
Solution:
Angle θ is in triangle DAC. The longest side in that angle triangle is AD hence, it is the hypotenuse.
Angle α is in triangle ABN. The longest side in that angle triangle is NB hence, it is the hypotenuse.
Angle β is in triangle DNC. The longest side in that angle triangle is DN hence, it is the hypotenuse.
Angle µ is in triangle ABC. The longest side in that angle triangle is CB hence, it is the hypotenuse.

Find the range of the function. f(x) =10-x^2
Answer: ( - ∞ , 10 ] , { y| y ≤ 10 }
Step-by-step explanation: You have to find the domain by finding where the function is defined. The range is the set of the values that correspond with the domain.
The range of the function f(x) = 10 - x^2 is all real numbers less than or equal to 10.
To find the range of the function f(x) = 10 - x^2, we need to consider the maximum and minimum values that f(x) can take. The parabola opens downwards since the coefficient of x^2 is negative, which means it has a maximum value and no minimum value. The vertex of this parabola occurs at x = 0, which gives us the maximum value of f(0) = 10. Therefore, the range of f(x) is all real numbers less than or equal to 10, which can be expressed as f(x) ≤ 10 or in interval notation, \\[10, -∞).
A toy boat is bobbing in the water.
Its distance D(t) (in m) from the floor of the lake as a function of time t (in seconds) can be modeled by a sinusoidal expression of the form a×sin(b×t) + d.
At t=0, when the boat is exactly in the middle of its oscillation, it is 1 m above the water's floor. The boat reaches its maximum height of 1.2 m after pi/4 seconds.
Find D(t).
Answer:
[tex]D(t) = 1\,m + (0.2\,m)\cdot \sin \left[\right(2\,\frac{rad}{s} \left)\cdot t\right][/tex]
Step-by-step explanation:
The sinusoidal expression has the following form:
[tex]D(t) = D+A\cdot \sin (B\cdot t)[/tex]
Where:
[tex]D[/tex] - Initial distance from the floor of the lake, in meters.
[tex]A[/tex] - Amplitude of oscillation, in meters.
[tex]B[/tex] - Angular frequency, in radians.
Now, each coefficient is derived as follows:
Initial distance from the floor of the lake
[tex]D = 1\,m[/tex]
Amplitude of oscillation
[tex]A = 1.2\,m - 1\,m[/tex]
[tex]A = 0.2\,m[/tex]
Angular frequency
From the statement it is known that boat reaches its maximum height in a quarter of its oscillation. Then, the angular frequency is:
[tex]B = \frac{\frac{1}{2}\pi \,rad}{\frac{1}{4}\pi \,s}[/tex]
[tex]B = 2\,\frac{rad}{s}[/tex]
The expression is:
[tex]D(t) = 1\,m + (0.2\,m)\cdot \sin \left[\right(2\,\frac{rad}{s} \left)\cdot t\right][/tex]

NEED ANSWER ASAP!!!Keiko and Eric each randomly surveyed people with cell phones. They recorded peoples'
ages (a years) and how many texts they send per day on average (t texts). For their respective data, they each drew a line of best-fit and determined its equation. They then compared equations and made inferences based only on the equations they calculated.
In this Age and Texting question, The true statement based on this information is that the younger a person is, the more likely they are to text. So the correct answer is option 3rd.
The two equations given represent the lines of best fit for the data collected by Keiko and Eric regarding peoples' age and the number of texts they send per day on average.
By analyzing the equations, we can make inferences about the relationship between age and the number of texts. Keiko's equation, t = -1.63a + 92.14, suggests that as age increases, the number of texts decreases.
Eric's equation, t = -1.05a + 80.97, also indicates a negative relationship between age and the number of texts, but with a slightly smaller slope. Therefore, the true statement based on this information is that the younger a person is, the more likely they are to text.

A. 1/80
B. 1/16
C. 15/16
D. 79/80
Answer:
Option C.
Step-by-step explanation:
It is given that Rusty’s favorite meal consists of a corn dog, tater wedges, and a fudgesicle.
Rusty has decided to order a corn dog and to choose his side and dessert randomly.
We need to find the probability that Rusty will not end up with his favorite meal.
Total number of sides = 4
Total number of desserts = 4
Total possibilities = 4 × 4 = 16
Possible ways of selecting tater wedges and a fudge sickle = 1
Probability that Rusty will end up with his favorite meal is
[tex]P=\dfrac{1}{16}[/tex]
Probability that Rusty will not end up with his favorite meal is
[tex]P'=1-P=1-\dfrac{1}{16}=\dfrac{15}{16}[/tex]
Hence, the correct option is C.

What is the volume, in cubic ft, of a cylinder with a height of 17ft and a base radius of 5ft, to the nearest tenths place?
Answer: 1335.2 ft^2
Step-by-step explanation: The volume of a cylinder formula is V=πr^2h. Just plug in 17 into h and 5 into r. Also the 2 is an exponent
The volume of the cylinder with a height of 17ft and a base radius of 5ft is approximately 1335.2 cubic feet.
What is the volume of a substance?The volume of a substance is the total space occupied by the substance in the three-dimensional space.
How do we determine the volume of a cylinder?The volume of a cylinder with the radius of the base r units, and a height of h units is given by the formula:
The volume of a cylinder = πr²h cubic units.
How do we solve the given question?In the question, we are asked to determine the volume of a cylinder with a base radius of 5ft and a height of 17ft.
We are given base radius r = 5ft, height h = 17ft.
To determine the volume, we use the formula of the volume of a cylinder:
The volume of a cylinder = πr²h cubic units.
or, Volume = π*(5²)*17 cubic feet
or, Volume = 3.1415*25*17 cubic feet (Taking π ≈ 3.1415)
or, Volume = 1335.1768 cubic feet ≈ 1335.2 square feet (Nearest tenths)
