In mathematics, a real number is a value of a continuous quantity that can represent a distance along a line. The adjective real in this context was introduced in the 17th century by René Descartes, who distinguished between real and imaginary roots of polynomials.
In addition to measuring distance, real numbers can be used to measure quantities such as time, mass, energy, velocity, and many more. Real numbers can be thought of as points on an infinitely long line called the number line or real line, where the points corresponding to integers are equally spaced

divide the sum of £7890 between charlotte and ali. given that the shares of charlotte at the end of 6 years may be equal to the shares of ali at the end of 8 years. compound interest being 5% ?
Based on the sum and the share value after the relevant number of years, Charlotte's share is $4,137.46 and Ali's share is $3,752.54.
What are Ali and Charlotte's shares?This can be solved using the substitution method:
Alice share + Charlotte's share = 7,890
As + Cs = 7,890
As = Cs
(As x Future value factor, 5%, 8 years) = (Cs x Future value factor, 5%, 6 years)
(As x 1.47745) = (Cs x 1.3400)
Cs = (As x 1.47745) / 1.3400
Cs = As x 1.1025746
Slotting these back in the original formula gives:
As + (As x 1.1025746) = 7,890
2.1025746As = 7,890
,As = 7,890 / 2.1025746
= $3,752.54
Charlotte's share will be:
= 7,890 - 3,752.54
= $4,137.46

We need to find the product of zero point zero two times of hundred.
This we can do by using the operation multiplication.
Multiplication is a method of finding the product of two or more numbers
We know that 100 we can write in the form of 10²
When 0.02 is multiplied with 10² we get 2
Hence, the product 0.02 x 100 = 0.02 x 10² =2

Please solve with explanation
Step-by-step explanation:
Since the ball is going upwards, then down, we have a parabola.
In the form of
[tex] - {x}^{2} + bx + c = 0[/tex]
The leading coeffeicent is negative because we are increasing then decreasing.
Let use t for seconds and h is height.
So we have a function
[tex]h(t) = - {t}^{2} + b(t) + c[/tex]
Since I'm have no information: I'm use calculus and physics to solve this.
All objects fall at the speed of
[tex] - 9.8 \frac{m}{ {s}^{2} } [/tex]
Which is the unit for acclereation.
Since we have are trying to a poisition versus time function, note that the anti derivative of acclereation will give us velocity. So let calculate that
[tex] \frac{d}{dx} (a) = - 9.8x[/tex]
Then note that the anti derivative of velocity is poistion.
[tex] \frac{d}{dx} (v) = - 4.9 {x}^{2} [/tex]
So we know our leading coeffeicent, is -4.9x^2.
The ball is initially launched at a speed of 15 m/s. So the first derivative of the function at x=0, should be 15.
[tex] \frac{d}{dx} (x) = - 4.9 {x}^{2} + bx[/tex]
[tex]v = - 9.8x + b[/tex]
Since 0 times anything is 0, b must be 15 in order to have a first derivative of 15.
Since 0,1 is the y intercept, c will be 1.
So our answer is
[tex] - 4.9 {x}^{2} + 15x + 1 = 0[/tex]
b). When x=1, we get a height of 11.1. Plug in 1 into the function, and we get 11.1
c). Set the function equal to zero and use quadratic formula to solve. You will get 3.13 seconds.
d. The max occurs when the velocity is 0. So we can first differentiate the function, which we will get
[tex] - 9.8x + 15 = 0[/tex]
Then we solve for x.
We get 1.5 seconds. Then plug in 1.5 into the function, we get 12.5. So the max height is 12.5 and this occurs at 1.5 seconds.
e).
Evaluate geometric series
Answer:
7.50 (nearest hundredth)
Step-by-step explanation:
General form of geometric progression: [tex]a_n=ar^{n-1}[/tex]
(where [tex]a[/tex] is the initial term and [tex]r[/tex] is the common ratio)
Given progression:
[tex]5\left(\dfrac13\right)^{n-1}[/tex]
Therefore:
[tex]a=5[/tex][tex]r=\dfrac13[/tex]Sum of a geometric series:
[tex]S_n=\dfrac{a(1-r^n)}{(1-r)}[/tex]
Substituting a = 5, r = 1/3 and n = 10 to find the sum to n = 10:
[tex]\implies S_{10}=\dfrac{5(1-\frac13^{10})}{(1-\frac13)}[/tex]
[tex]\implies S_{10}=7.499873987...[/tex]
[tex]\implies S_{10}=7.50 \textsf{ (nearest hundredth)}[/tex]

Answer:
the answer is A im not sure tho
Step-by-step explanation:
if you divide 10 divided by 2 it gives you 5 and then subtract it by 2.2 = 2.8
there goes your answer.
which function has a greater slope and a greater y -intercept than the linear function represented in the table
Answer:
~Y/n here~ I would think that the greater the slope the steeper the line. b is the slope of the line. So the slope means that a unit change in x, so the independent variable will result a change in y by the amount of b. Slope can show both steepness and direction in a linear function.

There are 45 new houses being built in a neighborhood. Last month, 2/3 of them were sold. This month 2/5, of the remaining houses were sold. How many houses are left to be sold?
Answer: 9 houses
Step-by-step explanation:
Step 1:
Since 2/3 of the houses were sold last month, 1/3 of them were left.
45 * 1/3 = 15 houses left last month
Step 2:
Since 2/5 of the remaining houses were sold this month, 3/5 of them were left
15 * 3/5 = 9 houses left to be sold

Here s a patter made from sticks
Answer:
Recursive formula of an arithmetic sequence is given by the expression,
Tn=a+(n−1)d
Where, Tn= nth term
a= First term of the sequence
n= Number of term
d= Common difference
Therefore, number of sticks in the 6th pattern are 32.
And number of sticks in the nth pattern are Tn=5n+2
From the picture attached,
Number of sticks in 1st pattern = 7
Number of sticks in 2nd pattern = 12
Number of sticks in 3rd pattern = 17
Sequence formed is 7, 12, 17..... nth term
This sequence has a common difference of 5 in each successive term so it will be an arithmetic sequence.
Therefore, nth term of the sequence will be,
Tn=a+(n−1)d
Tn=7+(n−1)5
Tn=5n+2
If n=6,
Tn=7+(6−1)5
Tn=7+25
Tn=32
Hope it helps !
Have a great day!
