What is an equation of the line that passes through the point (−2,−2) and is parallel to the line 5x−y=4?
Answers
Answer:
It is -5
Step-by-step explanation:
Answer: y=5x+8
Step-by-step explanation:
first you solve for y:
5x - y = 4
-5x -5x
↓
[tex]\frac{-y}{-1}[/tex] = [tex]\frac{-5x+4}{-1}[/tex]
↓
y = 5x - 4
slope of given line: 5
slope of a parallel line: 5
plug in slope:
y = 5x + b
find b, which is 8 :)
plug it in!
y = 5x + 8

Answer:
[tex]\boxed{\sf{y=-5x+8}}[/tex]Step-by-step explanation:
You can solve this problem using the slope formula and slope-intercept formula.
Slope formula:
[tex]\Longrightarrow: \sf{m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{rise}{run} }[/tex]
Slope-intercept formula:
[tex]\Longrightarrow: \sf{y=mx+b}[/tex]
M: represents the slope.B: represents the y-intercept.(1,3) and (2,-2)
y2=(-2)
y1=3
x2=2
x1=1
Rewrite the problem.
[tex]\sf{\dfrac{-2-3}{2-1}=\dfrac{-5}{1}=-5 }[/tex]
The slope is -5.y-intercept is 8.Rewrite the problem.
y=-5x+8
Therefore, the correct answer is y=-5x+8.I hope this helps you! Let me know if my answer is wrong or not.

A school psychologist at a large high school took a random sample of 16 students and asked how much sleep they get on a typical weekend night. The sample data were roughly symmetric with a mean of 8.75 hours and a standard deviation of 1.5 hours
Answers
Answer:
8.75 +/- 0.657
Step-by-step explanation:
The 90% confidence interval for the mean amount of sleep this population of students gets on a typical weekend night is 8.75±0.617
What is confidence interval?A confidence interval is a range around a measurement that conveys how precise the measurement is.
Given that, The sample data were roughly symmetric with a mean of 8.75 hours and a standard deviation of 1.5 hours, the confidence level value is 90%
confidence interval = x ± z·s/√n
= 8.75±1.645·1.5/√16
= 8.75±0.617
Hence, the 90% confidence interval for the mean amount of sleep this population of students gets on a typical weekend night is 8.75±0.617

What is volume of thi shown below?
Answers
Answer:
13613.46 cm^3
Step-by-step explanation:
Height of the conical top= 25 cm
Diameter of the conical top = 20 cm
Radius of the conical top = 10 cm
[tex]We\ know\ that,\\Volume\ of\ a\ cone\ = \frac{1}{3}\pi r^2h\\Hence,\\Volume\ of\ the\ conical\ top\ = \frac{1}{3}\pi 10^2*25 = \frac{1}{3} \pi 100*25\\= 833.3\pi\ cm^3[/tex]
Height of the cylindrical base = 35 cm
Diameter of the cylindrical base = 20 cm
Radius of the cylindrical base = 10 cm
[tex]We\ know\ that\ ,\\Volume\ of\ a\ cylinder\ = \pi r^2h\\Hence,\\Volume\ of\ the\ cylindrical\ base = \pi* 10*10*35\\=3500\pi\ cm^3[/tex]
[tex]Hence,\\Volume\ of\ the\ given\ figure\ = Volume\ of\ the\ conical\ top\ + Volume\ of\ the\ cylindrical\ base\ \\Hence,\\Volume\ of\ the\ given\ figure\ =833.3\pi +3500\pi \\=(3500+833.3)\pi \\=4333.3\pi \\=13613.46 cm^3[/tex]
Answer:
13,614cm³
Explanation:
There are 2 solid shapes in the object;
A cylinder and A cone
Volume of the cylinder = πr²h
Volume of the cone is 1/3πr³h
h of cone = 25cm
h of cylinder = 35cm
d of the cylinder and cone = 20cm
r = d/2 = 10cm
Volume of the cylinder = πr²h
= π(10)²×35 = 10,996cm³
Volume of the cone = 1/3πr²h
= 1/3π(10)²×25 = 2618cm³
Therefore the total volume of the object above =
Volume of the cylinder + Volume of the cone =
10,996cm³ + 2618cm³ = 13,614cm³

•Angle DEC is an exterior angle
•Angle ABE and EBC are supplementary angles
•Angle BCF and DEC are supplementary angles
•Angle BEC us a remote interior angle to exterior angle BCF
Answers
Triangle EBC have interior angles and exterior angles. The three appropriate options to the given question are:
B. Angle DEC is an exterior angle
C. Angle ABE and EBC are supplementary angles
E. Angle BEC is a remote interior angle to exterior angle BCF
An exterior angle is one that lies outside a given figure. Thus, it is not an interior angle of the figure. While an interior angle is an angle within the boundaries of the figure.
Supplementary angles are two or more angles whose measures add up to the value of angle on a straight line (i.e [tex]180^{o}[/tex]).
Thus considering the given triangle EBC, the appropriate options to the question are:
B. Angle DEC is an exterior angle
C. Angle ABE and EBC are supplementary angles
E. Angle BEC is a remote interior angle to exterior angle BCF
These three options best describes the relationships among the angles of the triangle.
