3) Mary deposits £10000 in an account which pays 5.6% compound
interest per year.
How much will Mary have in her account after 5 years?
Answer:
FV= £13,131.66
Step-by-step explanation:
Giving the following information:
Initial Investment (PV)= £10,000
Interest rate (i)= 5.6%
Number of periods (n)= 5 years
To calculate the future value (FV), we need to use the following formula:
FV= PV*(1 + i)^n
FV= 10,000*(1.056^5)
FV= £13,131.66

Robert plays cricket. He hit the ball in such a way that it goes up 180 feet
in 45 seconds. What is the speed of ball in feet per second?
Answer:
4 feet per second
Step-by-step explanation:
Hi there!
[tex]v=D/t[/tex] where v is velocity (speed), D is distance and t is time
Plug in the known values (D=180 feet, t=45 seconds)
[tex]v=180/45\\v=4[/tex]
Therefore, the speed of the ball is 4 feet per second.
I hope this helps!
Answer:
Honestly, I will say 4? I apologize if it is wrong though
Step-by-step explanation:
Because I divided 180 by 45.
i have like 0 clue what this is. so can someone also explain it please.
Answer:
What they are asking is in which box do each of the following numbers go into.
[tex]\sqrt{2}[/tex] and [tex]\frac{\pi }{2}[/tex] would go in the 'Between 1 and 2' box.
[tex]\sqrt{5}[/tex] goes under the 'Between 2and 3' box.
([tex]\sqrt{3.5}[/tex])^2 is the exact same as 3.5, as the square root and square cancel each other out, so it goes in the 'Between 3 and 4' box.
Hope that this helps!
What is the area of a rectangle with side
lengths x - 4 and 5x + 7?
Help pleaseeeeeeeeee
9514 1404 393
Answer:
47 -6√10
Step-by-step explanation:
As you know, the area of a square is the square of the side length. It can be helpful here to make use of the form for the square of a binomial.
(a -b)² = a² - 2ab + b²
(√2 -3√5)² = (√2)² - 2(√2)(3√5) + (3√5)²
= 2 - 6√10 + 3²(5)
= 47 -6√10
__
Check
√2-3√5 ≈ -5.29399 . . . . . . . . note that a negative value for side length makes no sense, so this isn't about geometry, it's about binomials and radicals
(√2-3√5)² ≈ 28.02633
47 -6√10 ≈ 28.02633

Simran used a simulation to predict the number of days of rain in his town. A number 1 or 2 indicates a week in which it rained. Numbers 3, 4, or 5 indicate a week in which it did not rain. The results of the simulation are shown above. What is the experimental probability that it will rain in Simran’s town in at least 1 of the next 4 weeks?
Answer:
The answer that I got for mine was 40%
Step-by-step explanation:
This is because there were 10 trials and 4 of the trials had rain. so 40 percent of the trials had rain. Hope it helps!
PLEASE Help I need the area in cm2 THanks Have a nice day!!
Answer:
132 cm^2
Step-by-step explanation:
Area of trapezoid = 1/2 ( (7 + 19) * 8) = 26*4 = 104 cm^2
Area of rectangle = 4 x 7 = 28 cm^2
104 cm^2 + 28 cm^2 = 132 cm^2

Answer:
c and a because x = a smaller number
Need this ASAP please
Answer:
C
Step-by-step explanation:
Because if we multiply by 2 both member we have
(x-12)(x-4)= 0
A product has a result that is equal to iif at least one of its factor is equal to 0, so we can solve this two equations:
x-12 = 0
x = 12
x-4 = 0
x = 4

CALL ME BY YOUR NAAAAAAAAAAAAAAAMEUse the Quadratic Formula
Use the Quadratic Formula to find the zeros of the given
expression. Be sure to show your steps!
2x2-7x+3
Plz help no links
Answer:
1/2 and 3
Step-by-step explanation:
The quadratic formula is as given:
( -b±√(b^2-4ac) )/2a
To use it, plug in the a,b and c values.
ax^2+bx+c
In this case a is equal to 2, b is equal to -7, and c is equal to 3
plugging it into our formula gives us:
(-(-7)±√(-7^2-4*2*3) )/2*2
Which is equal to:
7±√(49-24) / 4
= 7±√25 / 4
=7±5 / 4
=2/4, 12/4= 1/2, 3
