7. Hannah invests £750 and after 4 years has £844.13. Find the compound interest rate.
Answers
If the amount after 4 years is 844.13. Then the rate of the compound interest will be 3%.
What is compound interest?A loan or deposit's interest is computed using the starting principle and the interest payments from the ago decade as compound interest.
We know that the compound interest is given as
A = P(1 + r)ⁿ
Where A is the amount, P is the initial amount, r is the rate of interest, and n is the number of years.
Hannah contributes £750 and following 4 years has £844.13. Then the compound interest rate is given as,
844.13 = 750 (1 + r)⁴
(1 + r)⁴ = 1.1255
1 + r = 1.02999
r = 0.0299
r = 2.99%
r ≈ 3%
If the amount after 4 years is 844.13. Then the rate of the compound interest will be 3%.

the degree of f(x) is ?
the end behavior is the left side is ?
and the right side is ?
Answers
The degree of the polynomial is 5, and the end behavior is:
as x → ∞, f(x) → -∞
as x → -∞, f(x) → ∞
How to get the degree of a polynomial?
For any given polynomial, we define the degree as the largest exponent on the polynomial.
On this case we have:
f(x) = 2x^3 - 3x^5 - x^2 + 1
We can see that the largest exponent is 5, so the degree is 5.
Now, for the ending behavior.
If we have an odd degree (like in this case) we will have opposite ending behaviors in both ends of the domain.
If the leading coefficient is negative (like in this case, it is -3) then the end behavior will be:
as x → ∞, f(x) → -∞
as x → -∞, f(x) → ∞

What is perimeter?The perimeter of a shape is its boundary's length, regarded as a whole. A form's circumference can be calculated by adding the lengths of all of its sides and edges. Utilizing linear length units like centimeters, millimeters, yards, and feet, it is determined.
The total of all a parallelogram's sides is its perimeter.
Firstly, solve for vertices AB:
AB = √(17- 1)² + (1 - 1)² = 16
Then,
BC = √(22 - 17)² + (13 - 1)² = 13
Then,
CD = √(6 - 22)² + (13 - 13)² = 16
Lastly,
AD = √(6 - 1)² + (13 - 1)² = 13

What is the equation of the line that passes through the points (-2, -6) and (1, 2)?
Answers
The equation of the line that passes through the points (-2,-6) and (1,2) is y = 8x/3-2/3.
According to the question,
We have the following information:
Points through which line is passing = (-2,-6) and (1,2)
Now, we have the following values:
x1 = -2, y1 = -6
x2 = 1 and y2 = 2
We know that the following formula is used to find the slope of the line:
m = (y2-y1)/(x2-x1)
m = (2+6)/(1+2)
m = 8/3
Now, the following formula is used to find the equation of the line:
y-y1 = m(x-x1)
y+6 = 8/3(x+2)
y+6 = 8x/3+16/3
Subtracting 6 from both sides:
y = 8x/3+16/3-6
y = 8x/3-2/3
Hence, the equation of the line that passes through the points (-2,-6) and (1,2) is y = 8x/3-2/3.

if
x/y=y/z=z/x
show that x=y=z
Answers
Step-by-step explanation:
x/y = y/z = z/x
x = y²/z = zy/x and y = z²/x
x = y²/z
putting this into the 3rd part of the original equation :
z/x = z/ y²/z = z²/y²
now using the y identity of the second part there :
y = z²/x
z²/y² = z² / z⁴/x² = x²/z² (= z/x per previous equation)
so,
x²/z² = z/x
x³/z³ = 1
x/z = 1
x = z
then
y/z = y/x = z/x (= 1)
and therefore,
y/x = z/x meaning
y = z (and therefore = x)

x = y = z

The POINT of a hyperbola is one of two points such that the difference of the distances from any point on the hyperbola to the foci is a constant.
What is hyperbola?A hyperbola is a significant conic section in mathematics that is created by the intersection of a double cone with a plane surface, though not always at the center. A hyperbola is symmetric along its conjugate axis and resembles the ellipse in many ways. A hyperbola is subject to concepts like foci, directrix, latus rectus, and eccentricity. Examples of hyperbola that are frequently seen include the path taken by the tip of a sundial's shadow, the scattering trajectory of subatomic particles, etc.Here, we'll use instances that have been solved to better grasp the definition, formula, derivation, and standard forms of hyperbolas.Hence, The POINT of a hyperbola is one of two points such that the difference of the distances from any point on the hyperbola to the foci is a constant.

the initial number of views for a reader board was 25. the number of views is growing exponentially at a rate of 18% per week. what is the number of views expected to be four weeks from now? round to the nearest whole number.
Answers
The number of views in the four weeks round to the whole number is 48.
Here it is given that the initial number of views for a reader board was 25 and it gets increased at the rate of 18% per week.
We have to find the number of views in the fourth week.
On the first week the increase = 25 + 25× 18%
= 25 + 25 × 18/100
= 25 + 4.5
= 29.5
The second week increase = 29.5 + 29.5 × 18%
= 29.5 + 5.31
= 34.81
The third week increase = 34.81 + 34.81 × 18%
= 34.81 + 6.2658
= 41.0758
The fourth week increase = 41.0758 + 41.0758 × 18%
= 41.0758 + 7.393644
= 48.469444
Therefore the number of views in the four weeks is 48.
