Geometry work number 6
The geometry work number 6 has line MN parallel to line YX, line WY is parallel to line NX and line WX is parallel to line MO.
What are parallel linesIn geometry, parallel lines are straight lines that do not intersect or meet at any point.
Considering the triangle in the geometry work number 6,
the straight lines MN and YX can continue in same plene and will never meet at any point, so there are said to be parallel to each other.
the straight lines WY and NX can continue in their direction and will not intersect each other, so they are said to be parallel to each other.
and also, the straight lines WX and MO are parallel to each other because they can not intersect each other at any point.
Therefore, we can say that line MN is parallel to line YX, line WY is parallel to line NX and line WX is parallel to line MO.

Which equation represents how to determine the speed of an object?
The equation that the speed of an object is speed = distance/time
How to determine the equation of an objectFrom the question, we have the following parameters that can be used in our computation:
Parameter = Object
Argument = Speed
By definition, the speed of an object is the ratio of the distance moved by the object and the time travelled by the object
Mathematically, this can be represented as
Speed = Distance : Time
Express as fraction
Speed = Distance/Time

Todd is planning a vacation and is adding $5 per day towards his savings account for it. After 20 days he has a total of $150 in his savings
account.
a). Assuming this is linear relationship write an equation to model it.
b). How many days will it take Todd to build his savings up to a total of $250.
A) The equation of the model is 20x=100.
B) Todd will take 50 days to build his savings up to a total of $250.
What is meant by an equation?An assertion that two expressions containing variables or numerical values are equivalent is known as an equation. The first step in resolving a variable equation is to identify the values of the variables that lead to the equality being true. The variables that must be changed in order to solve the equation are referred to as the unknowns, and the unknown values that satisfy the equality are referred to as the equation's solutions.
1 day ------ $5
20 days -------?
x=20×5
x=$100
A) Let the savings per one day =$5
For 20 days it will be $100
And it is given as 20x=100
Where x=time in days
B) Todd has $150 dollars for 20 days
Actual savings for 20 days=100
? --------250
x=(20×250)/100

dellana company tested 50 products for 75 hours each. during this time, it experienced four breakdowns. compute the number of failures per hour, 937.50 hours is the mean time between failures.
What is mean time?The span of time before something occurs or before a given time frame expires. We can utilise the current computers while waiting for the new ones to arrive next week.
Given that,
dellana company tested 50 products
time =75 hours
Thus, total products in hours
= 50 products × 75 hours each
= 3750 product hours
Also said that, 4 breakdowns in 3750 product hours,
so, (4/3750) = 1.067 × 10⁻³ = 0.001067 breakdowns per hour.
Also, an average of 0.001067 breakdowns per hour = λ
therefore, mean time between failures:
= 1/ λ
= 1/0.001067
= 937.50 hours

If the derivative of y, dy/dx i the rate of change of y (alo known a the lope or gradient)
How can we ue the 2nd derivative of y, d2y/dx2 to determine whether the vertex of a quadratic i a maximum or minimum?
Why i thi the cae?
As d2y/dx2 is positive, the rate of change of gradient is positive, that means (2,-10) is a minimum point.
As stated in the video, the rate of change of dy/dx is the second derivative ( d2y/dx2 )
Thus, at a stationary point (dy/dx = 0), when d2y/dx2 < 0 meaning the rate of change of the gradient is negative the point is a maximum point. We can see that in the image below.
And at minimum points the rate of change of gradient is positive. Thus d2y/dx2 > 0 at minimum points.
A curve has equation y=x3 -12x +6 Find the coordinates of each stationary point, and the nature of these points (minimum or maximum).
Find when dy/dx = 0
dy/dx=3x2 -12
3x2 – 12 = 0
x2 =4
x = 2 or x=-2
when x = 2 y=-10 when x= -2 y=22
Thus, coordinates of stationary points are (2,-10) and (-2,22)
Now in order to find whether they are maximum or minimum points, we have to calculate d2y/dx2
d2y/dx2 = 6x
when x=2 d2y/dx2 = 12
As d2y/dx2 is positive, the rate of change of gradient is positive, that means (2,-10) is a minimum point.
when x= -2 d2y/dx2 = -12
As d2y/dx2 is negative, the rate of change of the gradient is negative, which means that (-2,22) is a maximum point

what is the greatest number of cups that can be completely filled with water from the container
The greatest number of cups that can be completely filled with water is 2.
What is the greatest number of cups that can be completely filled with water from the container?A fraction is simply a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split. In a simple fraction, the numerator as well as the denominator are both integers.
The greatest number of cups that can be completely filled with water will be:
1000ml = 1 liter
2/3l = 667ml
Therefore, the number of cups will be:

log base 25
The logarithm bases can you use to solve for x in the exponential equation [tex]4^{3+x}[/tex]= 25 is log base 4. So, option 3 is correct.
What is meant by exponential equation?Finding the slope (m) and y-intercept (b) of a line's graph will allow us to build a linear function with the formula y=mx+ b. We may build an exponential function of the form y=a+ bx given an exponential curve graph by locating the common ratio (b) and y-intercept (a) on the graph. If your function has the formula y = a + b x, where and are constants, a 0 and b > 0 and b 1, then it must be exponential. Your functions in quadratic equations were always to the second power. The exponent of exponential functions is a variable.
Given equation is [tex]4^{3+x}[/tex]= 25
Applying logarithm with base 4 to both sides.
log [tex]4^{3+x}[/tex]=log 25
(3+x)log 4=log25/log 4

The fifth number in the 7853rd row as required to be determined is; 47,116.
What is the 7,853rd term of the arithmetic sequence?It follows from the task content that the fifth number on the 7853rd row of the sequence is to be determined. By observation, each column of the sequence of numbers represents an arithmetic sequence of numbers in which case;
The common difference is; 6 - 0 = 12 - 6 = 17 - 11 = 6.
Therefore, since the nth term of an arithmetic sequence is given by the formula;T (n) = a + (n - 1) d.
where a = does term
n = number of terms
d = common difference
In this scenario, the first term is the fifth number on the first row = 4.Therefore, the fifth number on the 7853rd row is; T (7853) = 4 + (7853 - 1) × 6T = 4 + (7852 × 6)T = 4 + 47,112T = 47, 116.

The circumference of a circle is 7π ft. What is the area, in square feet? Express your answer in terms of
π
Answer:
49/4 π sq feet
Step-by-step explanation:
The circumference is the distance around a circle. The formula for circumference is:
C = πd
d stands for diameter. The circumference was given, 7π.
C = πd
= 7π
The diameter is 7. This is double the radius. The radius is half the circumference, so this radius is 7/2.
The area of the circle is:
Area = πr^2
= π(7/2)^2
= π(49/4)
=49/4 π
The area is 49/4 π
