Step-by-step explanation:
i) The best approach to estimate graphically the solution of [tex]4\cdot x^{2} - 4\cdot x - 1 = 0[/tex] is graphing the following system of equations:
[tex]y = 4\cdot x^{2}-4\cdot x - 1[/tex] (1)
[tex]y = 0[/tex] (2)
And labeling the points in which both intersects each other. We include the result in the image 'solution-i'. The approximate solutions are: [tex]x_{1} \approx -0.207[/tex], [tex]x_{2} \approx 1.207[/tex].

When melissa is born her parents invested 2,000 in a fund that paid an annual interest of 6%. How old will melissa be when the investment is worth at least $5,000?
Answer:
25 years
Step-by-step explanation:
Given data
Principal P= $2000
Interest rate r= 6%
FInal amount A=$5,000
The simple interest formula is given as
A=P(1+rt)
substitute and solve for t
5000=2000(1+0.06*t)
5000=2000+120t
5000-2000=120t
3000=120t
t= 3000/120
t= 25 years
Hence, for a simple interest investment, she will be 25 years

a cone is a solid made from a disc, a point not in the same plane as the discs and all points between them. true or flase?
Answer:
False.
Step-by-step explanation:
A cone is not a solid made from a disc, a point not in the same plane as the discs and all points between them.
Mathematically, the volume of a cone is given by the formula;
[tex] V = \frac{1}{3} \pi r^{2}h[/tex]
Where;
V is the volume of the cone.
r is the radius of the base of the cone.
h is the height of the cone.

Answer:
x = 31
Step-by-step explanation:
∠ A and ∠ B are vertical angles and are congruent, then
6x - 25 = 5x + 6 ( subtract 5x from both sides )
x - 25 = 6 ( add 25 to both sides )
x = 31

Ann and Bill share an amount of money in the ratio 7:n
Ann gets 28% of the money.
Work out the value of n
Answer:
48
Step-by-step explanation:
The value of n will be;
⇒ n = 18
What is mean by Ratio?A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.
Given that;
Ann and Bill share an amount of money in the ratio = 7 : n
And, Ann gets 28% of the money.
Now,
Since, Ann and Bill share an amount of money in the ratio = 7 : n
And, Ann gets 28% of the money.
Thus, Bill gets the money = 100 - 28%
= 72%
So, The unit ratio for the Ann = 28 / 7
= 4
Hence, Bill ratio will be = 72/4
= 18
Thus, The ratio of an amount of money = 7 : 18
Hence, The value of n = 18.

Answer:z=47
Step-by-step explanation:
You're doing this because if you have z-31=16 you have to + 31 to 16 which would give you 47 then that would be a one step equation
z-31=16
you would make a line between the equal sign so it is organized then plus 31 to sixteen then that would get you to 47
