A circular grassy area of(172 square
feet is being watered by a sprinkler
set in the middle. How far does the
water spray from the sprinkler as it
rotates? Round your answer to the
nearest foot.
The distance the water sprays as the sprinkler rotates is 7.34 ft
Since the grassy area is circular, its area is the area of a circle.
Area of a circleSo, A = πr² where r = radius of circle = distance sprinkler sprays
The distance the water spraysMaking r subject of the formula, we have
r = √(A/π)
Since A = 172 ft², substituting the values of the variables into the equation, we have
r = √(A/π)
r = √(172 ft²/π)
r = √(172 ft²/3.142)
r = √(54.749 ft²)
r = 7.34 ft
So, the distance the water sprays as the sprinkler rotates is 7.34 ft

What is the exact circumference of a circle with a radius of 15 cm?
o 10 pi cm
o 15 pi cm
o 30 pi cm
o 60 pi cm
Answer:

The axis of symmetry for the graph of the function f(x)=3x2 bx 4 is x equals three-halves. What is the value of b?.
The axis of symmetry for the graph of the function f(x) = 3x2 + bx + 4 is x = 3/2 , the value of b is -9.
What is an axis of symmetry?
Axis of symmetry is a line that divides an object into two equal halves, thereby creating a mirror-like reflection of either side of the object.
Given
The axis of symmetry for the graph of the function f(x) = 3x2 + bx + 4 is x = 3/2 .
The axis of the symmetry is given by;
[tex]\rm x=\dfrac{-b}{2a}[/tex]
The value of x is 3/2 and a is 3.
Substitute all the values in the formula
[tex]\rm x=\dfrac{-b}{2a}\\\\\dfrac{3}{2}=\dfrac{-b}{2 \times 3}\\\\\dfrac{3}{2}=\dfrac{-b}{6}\\\\ -b = \dfrac{6 \times 3}{2}\\\\ b = \dfrac{=18}{2}\\\\b =-9[/tex]
Hence, the value of b is -9.

Find cot and cos
If sec = -3 and sin 0 > 0
Answer:
Second answer
Step-by-step explanation:
We are given [tex]\displaystyle \large{\sec \theta = -3}[/tex] and [tex]\displaystyle \large{\sin \theta > 0}[/tex]. What we have to find are [tex]\displaystyle \large{\cot \theta}[/tex] and [tex]\displaystyle \large{\cos \theta}[/tex].
First, convert [tex]\displaystyle \large{\sec \theta}[/tex] to [tex]\displaystyle \large{\frac{1}{\cos \theta}}[/tex] via trigonometric identity. That gives us a new equation in form of [tex]\displaystyle \large{\cos \theta}[/tex]:
[tex]\displaystyle \large{\frac{1}{\cos \theta} = -3}[/tex]
Multiply [tex]\displaystyle \large{\cos \theta}[/tex] both sides to get rid of the denominator.
[tex]\displaystyle \large{\frac{1}{\cos \theta} \cdot \cos \theta = -3 \cos \theta}\\\displaystyle \large{1=-3 \cos \theta}[/tex]
Then divide both sides by -3 to get [tex]\displaystyle \large{\cos \theta}[/tex].
Hence, [tex]\displaystyle \large{\boxed{\cos \theta = - \frac{1}{3}}}[/tex]
__________________________________________________________
Next, to find [tex]\displaystyle \large{\cot \theta}[/tex], convert it to [tex]\displaystyle \large{\frac{1}{\tan \theta}}[/tex] via trigonometric identity. Then we have to convert [tex]\displaystyle \large{\tan \theta}[/tex] to [tex]\displaystyle \large{\frac{\sin \theta}{\cos \theta}}[/tex] via another trigonometric identity. That gives us:
[tex]\displaystyle \large{\frac{1}{\frac{\sin \theta}{\cos \theta}}}\\\displaystyle \large{\frac{\cos \theta}{\sin \theta}[/tex]
It seems that we do not know what [tex]\displaystyle \large{\sin \theta}[/tex] is but we can find it by using the identity [tex]\displaystyle \large{\sin \theta = \sqrt{1-\cos ^2 \theta}}[/tex] for [tex]\displaystyle \large{\sin \theta > 0}[/tex].
From [tex]\displaystyle \large{\cos \theta = -\frac{1}{3}}[/tex] then [tex]\displaystyle \large{\cos ^2 \theta = \frac{1}{9}}[/tex].
Therefore:
[tex]\displaystyle \large{\sin \theta=\sqrt{1-\frac{1}{9}}}\\\displaystyle \large{\sin \theta = \sqrt{\frac{9}{9}-\frac{1}{9}}}\\\displaystyle \large{\sin \theta = \sqrt{\frac{8}{9}}}[/tex]
Then use the surd property to evaluate the square root.
Hence, [tex]\displaystyle \large{\boxed{\sin \theta=\frac{2\sqrt{2}}{3}}}[/tex]
Now that we know what [tex]\displaystyle \large{\sin \theta}[/tex] is. We can evaluate [tex]\displaystyle \large{\frac{\cos \theta}{\sin \theta}}[/tex] which is another form or identity of [tex]\displaystyle \large{\cot \theta}[/tex].
From the boxed values of [tex]\displaystyle \large{\cos \theta}[/tex] and [tex]\displaystyle \large{\sin \theta}[/tex]:-
[tex]\displaystyle \large{\cot \theta = \frac{\cos \theta}{\sin \theta}}\\\displaystyle \large{\cot \theta = \frac{-\frac{1}{3}}{\frac{2\sqrt{2}}{3}}}\\\displaystyle \large{\cot \theta=-\frac{1}{3} \cdot \frac{3}{2\sqrt{2}}}\\\displaystyle \large{\cot \theta=-\frac{1}{2\sqrt{2}}[/tex]
Then rationalize the value by multiplying both numerator and denominator with the denominator.
[tex]\displaystyle \large{\cot \theta = -\frac{1 \cdot 2\sqrt{2}}{2\sqrt{2} \cdot 2\sqrt{2}}}\\\displaystyle \large{\cot \theta = -\frac{2\sqrt{2}}{8}}\\\displaystyle \large{\cot \theta = -\frac{\sqrt{2}}{4}}[/tex]
Hence, [tex]\displaystyle \large{\boxed{\cot \theta = -\frac{\sqrt{2}}{4}}}[/tex]
Therefore, the second choice is the answer.
__________________________________________________________
Summary
Trigonometric Identity[tex]\displaystyle \large{\sec \theta = \frac{1}{\cos \theta}}\\ \displaystyle \large{\cot \theta = \frac{1}{\tan \theta} = \frac{\cos \theta}{\sin \theta}}\\ \displaystyle \large{\sin \theta = \sqrt{1-\cos ^2 \theta} \ \ \ (\sin \theta > 0)}\\ \displaystyle \large{\tan \theta = \frac{\sin \theta}{\cos \theta}}[/tex]

It is well-documented that watching TV, working on a computer, or any other activity involving artificial light can be harmful to sleep patterns. Researchers wanted to determine if the artificial light from e-Readers also disrupted sleep. In the study, 12 young adults were given either an iPad or printed book for four hours before bedtime. Then, they switched reading devices. Whether the individual received the iPad or book first was determined randomly. Bedtime was 10 P.M. and the time to fall asleep was measured each evening. It was found that participant took an average of 10 minute s longer to fall asleep after reading on an iPad. The P-value for the test was 0.009.
(a) What is the research objective?
(b) What is the response variable? It is quantitative or qualitative?
(c) What is the treatment?
(d) Is this a designed experiment or observational study? What type?
(e) The null hypothesis for this test would be that there is no difference in time to fa ll asleep with an e-Reader and print ed book. The alternative is that there is a difference. Interpret the P-value.
Answer:
(a) the objective is to determine if the artificial light from e-Readers also disrupted sleep.

You are taking a class in which your grade is determined from: Quizzes: 15%
Exam (3): 15% for each
Homework: 10%
Final: 30%
Your scores are: Average quiz mean = 85 Exam = 78,81, 92 Homeworks mean = 85 Your final = 89
If the minimum average for B + is 87, did you get B + at the end of the semester. (Show your working.)
Answer:
No, you did not get a B+, you got an 85.6% for the class
Step-by-step explanation:
So, let's split the grades into different parts:
Quiz: 15%
Exam1: 15%
Exam2: 15%
Exam3: 15%
Homework: 10%
Final: 30%
Each part of the grade adds up together to be 100%, so here, we are going to multiply each weighting of the grade with the average amount of points you got for each assignment then add it all up.
(Notice how I convert the percentages to decimals to make it easier to multiply)
Quiz: 0.15(85) = 12.75
Exam1: 0.15(78) = 11.70
Exam2: 0.15(81) = 12.15
Exam3: 0.15(92) = 13.80
Homework: 0.10(85) = 8.50
Final: 0.3(89) = 26.70
Adding these all up:
12.75 + 11.70 + 12.15 + 13.80 + 8.50 + 26.70 = 85.6
You got an 85.6% for the class, which is not a B+

Relative to the sinusoidal axes (dotted lines) what is the equation of this sinusoid?
Step-by-step explanation:
We know that the function period is 3 so the b value is
[tex] \frac{2\pi}{b} = 3[/tex]
[tex]b = \frac{2\pi}{3} [/tex]
So our b is 2 pi/3.
The midline is -3 and the amplitude is 2.Since this function isn't symmetric about y axis, and looks symmetric about orgin, we trig function will be Sine so we have
[tex]2 \sin ( \frac{2\pi}{3}x ) - 3[/tex]
The function passes through 0,-3 and our function on the graph passes through 1,-3 so we shift one unit to left.
[tex]2 \sin(\frac{2\pi}{3}(x + 1) ) - 3[/tex]
