What is division?Division is an arithmetic operation that involves the splitting or sharing of a quantity into equal parts or groups. It is the inverse operation of multiplication. When we divide one number by another, we are determining how many times the divisor can be subtracted from the dividend.
The division process involves repeatedly subtracting the divisor from the dividend until no more subtractions are possible, or until the remainder is less than the divisor.
We can see here that as we subtract x from x, we have 0 and then we bring the 1 down. The 1 brought down is the remainder.

2) f(x) 0.4 (x + 2)(x - 5)
3) f(x) -0.4 (x - 2)(x + 5)
4) f(x) 0.4 (x - 2)(x + 5)
The quadratic equation in vertex form is f(x) = 0.4(x - 2)² + 5
How to determine the equation in vertex form
From the question, we have the following parameters that can be used in our computation:
The graph
Where, we have the vertex to be
(h, k) = (2, 5)
A quadratic equation in vertex form is represented as
f(x) = a(x - h)² + k
So, we have
f(x) = a(x - 2)² + 5
Using the points, we have
a = 0.4
Substitute the known values into the equation
f(x) = 0.4(x - 2)² + 5
Hence, the equation in vertex form is f(x) = 0.4(x - 2)² + 5
Joe and mike both ran the same race. Joe finish the race 4 minutes before mike. If mike finish the race at 4:02pm what time did joe finish the race

Joe finished the race at 3:58 PM, 4 minutes before Mike, who finished at 4:02 PM. Subtract 4 minutes from 4:02 PM to get Joe's finish time. The result is 3:58 PM.
Joe and Mike both participated in the same race, but Joe finished 4 minutes earlier than Mike. We know that Mike finished the race at 4:02 PM. To determine Joe's finish time, we need to subtract 4 minutes from 4:02 PM.
Here are the steps:
Start with Mike's finish time: 4:02 PM.Subtract 4 minutes from 4:02 PM: 4:02 PM - 4 minutes = 3:58 PM.Therefore, Joe finished the race at 3:58 PM.
Find any 3 (x,y) pairs that are solutions for the equation 2x-5y=10 . Show your work
Answer:
(0,-2), (5,0) and (10,2).
Step-by-step explanation:
Given equation is [tex]2x-5y=10[/tex].
Now we need to find 3 pairs of solutions in (x,y) form for the given equation.
As [tex]2x-5y=10[/tex] is a linear equation so we are free to pick any number for x like x=0, 5, 10
Plug x=0 into [tex]2x-5y=10[/tex], we get:
[tex]2(0)-5y=10[/tex]
[tex]0-5y=10[/tex]
[tex]-5y=10[/tex]
[tex]y=\frac{10}{-5}[/tex]
[tex]y=-2[/tex]
Hence first solution is (0,-2)
We can repeat same process with x=5 and 10 to get the other solutions.
Hence final answer is (0,-2), (5,0) and (10,2).
The answers is:
The three points that are solution for the equation are:
[tex](5,0)\\(0,-2)\\(6,0.4)[/tex]
Why?To find 3 pairs (x,y) or points that are solutions for the equation, we could find where the function intercepts the x-axis and y-axis, we must remember that the domain of a line is all the real numbers, so by using any input, we will find a solution, which means finding a point that belongs to the line.
So,
Finding the axis intercepts of the line, we have:
x-axis intercept:
Making "y" equal to 0, we have:
[tex]2x-5y=10[/tex]
[tex]2x-5*(0)=10[/tex]
[tex]2x=10[/tex]
[tex]x=\frac{10}{2}=5[/tex]
We have that the interception point with the x-axis is (5,0)
y-axis intercept:
Making "x" equal to 0, we have:
[tex]2x-5y=10[/tex]
[tex]2*(0)-5y=10[/tex]
[tex]0-5y=10[/tex]
[tex]5y=-10[/tex]
[tex]y=\frac{-10}{5}=-2[/tex]
We have that the interception point with the y-axis is (0,-2)
As we know, the domain of a line is equal to the real numbers, Now, we have that any between the points (5,0) and (0,-2) will belong to the line, so, let's try with a point wich x-coordinate (input) is equal to 6 and then find the y-coordinate (output) if the point satisfies the equality, it belongs to the equation to the line.
Substituting x equal to 6, we have:
[tex]2*(6)-5y=10[/tex]
[tex]12-5y=10[/tex]
[tex]12-10=5y[/tex]
[tex]y=\frac{12-10}{5}=\frac{2}{5}[/tex]
So, the obtained point is:
[tex](6,\frac{2}{5})[/tex]
or
[tex](6,0.4)[/tex]
Now, let's prove that it belongs to the equation of the line by substituting it into the equation:
[tex]2*(6)-5*\frac{2}{5}=10[/tex]
[tex]12-2=10[/tex]
[tex]10=10[/tex]
We can see that the equality is satisfied, it means that the point belongs to the line.
Hence, the three points that are solutions for the equation are:
[tex](5,0)\\(0,-2)\\(6,0.4)[/tex]

The formula for determining the frequency, f, of a note on a piano is f=440(2)^h/12 where h is the number of half-steps from the A above middle C on the keyboard. A note is six half-steps away from the A above middle C. The frequency of the A above middle C is 440 Hz. How much greater is the frequency of the new note compared with the frequency of the A above middle C?
A)29.3%
B)41.4%
C)70.7%
D)182.3%
Answer:
i think it is c
Step-by-step explanation:
Answer:
41.4%
Step-by-step explanation:
The formula for determining the frequency: [tex]f(h)=440(2)^{\frac{h}{12}}[/tex] --A
where h is the number of half-steps from the A above middle C on the keyboard.
A note is six half-steps away from the A above middle C.
Now we are supposed to find How much greater is the frequency of the new note compared with the frequency of the A above middle C?
Now initially there is no half steps .
So, substitute h =0
[tex]f(0)=440(2)^{\frac{0}{12}}[/tex]
[tex]f(0)=440[/tex]
Now we are given that A note is six half-steps away from the A above middle C
So, substitute h =6
[tex]f(6)=440(2)^{\frac{6}{12}}[/tex]
[tex]f(6)=622.25[/tex]
Now To find change percentage
Formula: [tex]=\frac{\text{final} - \text{initial}}{\text{Initial}} \times 100[/tex]
[tex]=\frac{622.25- 440}{440} \times 100[/tex]
[tex]=0.414 \times 100[/tex]
[tex]=41.4\%[/tex]
Hence the frequency of the new note is 41.4% greater with the frequency of the A above middle C.
Erin discovered a relationship between numbers. The Venn diagram shows how Erin sorted a group of numbers. Using the Venn diagram, where should Erin put the number 49?
Answer:
W
Step-by-step explanation:
On the venn diagram, you can see that everything in the W section is a multiple of 7. Everything in the Z section is an even number and everything in Y(the middle section) is both an even number and a multiple of 7. Since 49 is a multiple of 7 but not an even number, it would go in the W section.
The number 49 should be placed in the 'W' portion of the venn diagram
From the venn diagram, we can make the following inference;
W = 7, 21, 35
Y = 14, 28
Both W and Y contains numbers that are multiples of 7
Y contains numbers that are even numbers which are multiples of 7
W contains numbers that are odd and are multiples of 7
The number 49 is also a multiple of 7 and odd.
Hence, 49 would belong to the 'W' portion of the Venn.

1. The product of a number x and 6 is 21
2. The sum of the quantity x- 3 and y
3. The quotient of x and z is y
4. The difference of 2 and x is p.
Answer:
1) 6x = 21
2) x + y - 3
3) x/z = y
4) 2-x = p
Step-by-step explanation:
1. The product of a number x and 6 is 21
A product is a multiplication. A product of a and b is a * b.
We then have a product of x and 6, that x * 6, which we write usually in the format 6x.
is 21: that means it's equal to 21....
so 6x = 21.
2. The sum of the quantity x- 3 and y
The sum is an addition. The sum of a and b is a + b.
In this case, the first part is x - 3, the second part is y
So, x - 3 + y, which we usually rewrite as x + y - 3
3. The quotient of x and z is y
A quotient is a division.
So, quotient of x and z is x/z.
x/z = y
4. The difference of 2 and x is p.
A difference is a subtraction.
Difference of 2 and x is 2 - x
2 - x = p
The verbal sentences/phrases are translated into algebraic expressions or equations as: 1) 6x = 21, 2) (x - 3) + y, 3) y = x/z, and 4) p = 2 - x. Each expression/equation captures a different mathematical relationship, such as product, sum, quotient, and difference.
Explanation:To translate each verbal sentence/phrase into an algebraic expression or equation, we will take them one at a time:
The product of a number x and 6 is 21: This can be translated into the equation 6x = 21.The sum of the quantity x - 3 and y: The algebraic expression for this is (x - 3) + y.The quotient of x and z is y: This corresponds to the equation x/z = y, or as an expression, y = x/z.The difference of 2 and x is p: This translates to the equation p = 2 - x.Remember to check your final expressions or equations to ensure they make sense and are simplified where possible.

Which linear inequality is represented by the graph?
Answer:
The graph of an inequality in two variables is the set of points that represents all solutions to the inequality. A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality. The boundary line is dashed for > and < and solid for ≤ and ≥.
At the beach, Pancho and his sister both built sandcastles and then measured their heights. Pancho's sandcastle was 3/5 of a foot tall and his sister's was 2/5 of a foot tall. How much taller was Pancho's sandcastle than his sister's?
1/5 of a foot
Simply subtract the height of Pancho’s sandcastle (3/5 of a foot) minus the height of his sister’s sandcastle (2/5 of a foot) to find a difference of 1/5 of a foot, meaning Pancho’s sandcastle was 1/5 of a foot taller than his sister’s sandcastle.

Where a and b are legs and c is the hypotenuse.
If we had the measurements 27, 36, and 45...
[tex]a^2+b^2=c^2 \\ \\ 27^2+36^2=45^2 \\ \\ 729+1296=2025 \\ \\ 2025 = 2025[/tex]
So it is a right triangle because [tex]a^2+b^2=c^2[/tex]
The values of a, b, and c are given.
[tex]a=27 \\ b=36 \\ c=45[/tex]
Converse blanks: the sum of the legs squared is equal to the square of the hypotenuse; right.
a = 27, b = 36 (a and b can be switched), c = 45 --> the hypotenuse is always the longest side.
a² + b² = c²
Substitute: 27² + 36² = 45²
Simplify: 729 + 1296 = 2025
Simplify: 2025 = 2025
This is a right triangle because the sum of the lengths of the legs squared is equal to the length of the hypotenuse squared.
(also good note, the sides have a ratio of 3 : 4 : 5, which will always make a right triangle)

Answer: D) 10 sin (πx) - 5
Step-by-step explanation:
The range (maximum - minimum) is 5 - (-15) = 20
The amplitude (A) is range (20) ÷ 2 = 10
The vertical shift (D) is maximum (5) - amplitude (10) = -5
Of the given options, only A & D are candidates. Now we need to decide if it is a cos graph (A) or a sin graph (D). If we shift the graph up 5 units (to eliminate the vertical shift) , the graph would pass through the origin. Thus it is a sin graph and the answer must be option D.
work out the area of this quarter circle of radius 8cm, Give you answer in terms of pi
Answer:
The area of the quarter circle is [tex]16\pi\ cm^{2}[/tex]
Step-by-step explanation:
we know that
The area of a quarter circle is equal to
[tex]A=\frac{1}{4}\pi r^{2}[/tex]
we have
[tex]r=8\ cm[/tex]
substitute the value
[tex]A=\frac{1}{4}\pi (8)^{2}[/tex]
[tex]A=16\pi\ cm^{2}[/tex]
The area of a quarter circle with a radius of 8cm is 16π square cm. This result is obtained by first calculating the area of a full circle using the formula A = πr² and then dividing by 4 (since a quarter circle is one-fourth of a full circle).
Explanation:The area of a full circle is given by the formula A = πr², where 'r' is the radius of a circle and 'π' is a mathematical constant, approximately 3.14. However, we are dealing with a quarter circle, not a full circle. A quarter circle is simply one-fourth of a full circle. Therefore, you have to divide the area of the full circle by 4 to get the area of the quarter circle.
So here's how you calculate the area of the quarter circle having a radius of 8cm:
First calculate the area of the full circle: A = πr² = π * 8² = 64π square cm. Then calculate the area of the quarter circle: Quarter Circle Area = A/4 = 64π/4 = 16π square cm.So, the area of the quarter circle with a radius of 8 cm is 16π square cm.

A particular lawn mower is on sale at two different stores the original price at both stores was $130. Watson’s garden shop is advertising the lawn mower for 50% off. Hartman’s home center reduced the mower 40%, and then took an additional 15% off the reduced price. Which lawn mower is the better deal?
Answer:
Watson's garden shop has the better deal on the lawn mower.
Hope this helped :)
Step-by-step explanation:
Watson's $130 - 50% = $65
Hartman's $130 - 40% = $78
$78 - 15% = About $66
Answer:
The deal of Watson’s garden shop is better.
Step-by-step explanation:
Given,
The original price = $ 130,
After 50% off,
The new price would be,
[tex]P_1=130\times \frac{(100-50)}{100}[/tex]
[tex]=\frac{130\times 50}{100}[/tex]

The average man takes 7192 steps a day about how many steps does the average man take in a year
Answer:
2625080
Step-by-step explanation:
The average man takes about 2,625,080 steps in a year, assuming 365 days in a non-leap year.
As we know:
No. of days in a year = 365 days ( non-leap year)
Given:
No. of steps the average man takes = 7192 steps in a day
So, in a year he will take:
7192 steps/day × 365 days/year
= 2,625,080 steps/year
So, the average man takes about 2,625,080 steps in a year.
Note: This calculation assumes a non-leap year with 365 days.
