Answer:
Step-by-step explanation:
This is arithmetic since adding 4 to each term gets us to the next term in the sequence. That means that the common difference, d, is 4. The general arithmetic explicit formula is
[tex]a_n=a_1+d(n-1)[/tex] and using the info given when a1 = 3 and d = 4:
[tex]a_n=3+4(n-1)[/tex] or, if you want to make it easier to deal with:
[tex]a_n=4n-1[/tex] (I just distributed through the parenthesis and then combined like terms. As you can see, arithmetic sequences are linear).

Question 10 of 10 Classify the following triangle. Check all that apply. 7 A. Right B. Acute C. Isosceles D. Scalene E. Equilateral F. Obtuse
D & F
Step-by-step explanation:
D scale because all sides are different lengths
F obtuse because one angle is greater than 90 degrees
Look up definition of the other properties and you will see they don't apply
The given triangle is a obtuse and scalene triangle
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
The given triangle is an obtuse triangle and scalene triangle.
A triangle whose any one of the angles is an obtuse angle or more than 90° is known as obtuse triangle.
A triangle in which all the three sides have different lengths then it is called as scalene triangle.
Hence, the given triangle is a obtuse and scalene triangle.

What is m angle KNL?
Enter your answer in the box.
Answer:
KNL = 102
Step-by-step explanation:
The angles are vertical angles and vertical angles are equal
5x+2 = 3(x+14)
5x+2 = 3x+42
Subtract 3x from each side
5x-3x+2 = 3x+42-3x
2x+2 = 42
Subtract 2 from each side
2x+2-2 = 42-2
2x = 40
Divide by 2
2x/2 = 40/2
x = 20
We want to find KNL
KNL = 3(x+14) = 3(20+14) = 3 ( 34) = 102

Situation: Find the substance's half-life, in days. Round your answer to the nearest tenth. A 33 gram sample of a substance that's used for drug research has a k-value of 0.1081. Enter the correct answer. N = Noe DONE No = initial mass (at time t = 0) 000 OO N = mass at time t k= = a positive constant that depends on the substance itself and on the units used to measure time t = time, in days
Answer:
1051 or..
10.51
Step-by-step explanation:
Since 33=30 and 0.1081 is supposed to be as a percentage since its already a decimal you could just round it and make it into a fraction then once you get the answer to the fraction it would either be 1081 since 0.1081 as a fraction is 1081/10000 or you could make into 10.81 as a decimal but after that you subtract "30 - 1,081" or 10.81 -30" either one of them and each of those numbers would give you the same exact number. Answer: 1051 or as a decimal 10.51

Find the value of g in the figure given below.
Assume that the lines are parallel.
Answer:
d=60-degree (Vertically opposite angles)
e=d=60-degree (Alternate angles)
e+g=180-degree (Being in a straight line)
60+g=180
g=180-60
g=120-degree
Answer:
angle g = 20 degree
Step-by-step explanation:
60 degree + angle g = 180 degree (being co exterior angles)
angle g = 180 - 60
angle g = 120 degree
Note : co interior angles are the angles formed on the exterior of the two parallel lines and which are on the same side of the transversal .
The volume of a cylinder is 156 pi centimeters cubed. What is the volume of a cone with the same base and height as the cylinder?
Answer:
52 pi centimeters cubed
Step-by-step explanation:
volume of a cylinder = πr^2h
Volume of a cone 1/3(πr^2h)
π = 22/7
r = radius
The volume of a cone is one-third that of a cylinder
volume of cone = 156/3 = 52

14. A cellular telephone company recently conducted research into the length of calls (in
minutes) made by customers. In a random sample of 30 calls, the sample mean was
x= 18.6 minutes and the standard deviation was s=5.2 minutes. Construct and interpret
a 90% confidence interval for true mean call length. (4-step process)
Answer:
The correct answer is "16.987, 20213".
Step-by-step explanation:
Given that,
[tex]n=30[/tex]
[tex]\bar x=18.6[/tex]
[tex]s = 5.2[/tex]
[tex]df=30-1[/tex]
[tex]=29[/tex]
[tex]\alpha = 0.10[/tex]
By using the table, the critical values of t will be:
= [tex]\pm 1.699[/tex]
Now,
The confidence interval will be:
= [tex]\bar x \pm \frac{t\times s}{\sqrt{n} }[/tex]
By putting the values, we get
= [tex]18.6 \pm \frac{1.699\times 5.2}{\sqrt{30} }[/tex]
= [tex]16.987,20.213[/tex]
