The curve y = ax^n, where a and n are constants, passes through the points (2.25, 27), (4, 64) and (6.25, p). Without using logarithms, calculate the value of a, of n and of p.
a. The value of n is 3/2
b. The value of a is 8.
c. The value of p is 125
The curve is an exponential function
What is an exponential function?An exponential function is a function of the form y = axⁿ where a and n are constants
a. How to find the value of n?
Since y = axⁿ where a and n are constants, passes through the points (2.25, 27), (4, 64) and (6.25, p), substituting these points into the equation, we have
y = axⁿ
27 = a(2.25)ⁿ (1)
64 = a(4)ⁿ (2)
P = a(6.25)ⁿ (3)
Dividing (2) by (1), we have
64/27 = a(4)ⁿ/a(2.25)ⁿ
4³/3³ = (4 ÷ 2¹/₄)ⁿ
4³/3³ = (4 ÷ ⁹/₄)ⁿ
4³/3³ = (4 × 4/9)ⁿ
4³/3³ = (16/9)ⁿ
4³/3³ = (4²/3²)ⁿ
(4/3)³ = (4/3)²ⁿ
Equating exponents, we have
2n = 3
n = 3/2
The value of n is 3/2
b. What is the value of a?Using equation (2)
64 = a(4)ⁿ
a = 64/(4)ⁿ
substituting n = 3/2 into the equation, we have
[tex]a = \frac{64}{4^{\frac{3}{2} } } \\= \frac{64}{(\sqrt{4 } )^{3} } \\= \frac{64}{2^{3} } \\= \frac{64}{8} \\= 8[/tex]
So, the value of a is 8.
c. What is the value of p.Using equation (3), we have
P = a(6.25)ⁿ (3)
substituting the values of a and n into the equation,we have
[tex]P = 8(6.25)^{\frac{3}{2} } \\= 8(\sqrt{6.25}) ^{3} \\= 8(2.5}) ^{3} \\= 8(15.625})\\= 125[/tex]
The value of p is 125

B
Both functions have a domain of all real numbers.
C
The x-intercept of k(x) is greater than the x-intercept of j(x).
D
Function j(x) is greater than function k(x) for all values of x.
The correct statement regarding the logarithmic functions is:

The equation for the variable 'c' is c = d(q² + 1)/(q² - 1). By using simple arithmetic operations on the original equation, the required equation can be obtained.
What is an equation?An equation is a relationship between two expressions given by a mathematical statement.
There are different types of equations. They are linear equations, quadratic, polynomial, etc.
Solving for c in the given equation:The given equation is
q = √((c + d)/(c - d))
Squaring on both, root gets canceled out
⇒ q² = (c + d)/(c - d)
⇒ q²(c - d) = (c + d)
⇒ cq² - dq² = c + d
Separating like terms aside,
cq² - c = d + dq²
⇒ c(q² - 1) = d(q² + 1)
⇒ c = d(q² + 1)/(q² - 1)
Therefore, the required equation is c = d(q² + 1)/(q² - 1).

Do you remember that we cannot add fractions when they have unlike denominators? We can onyl add fractions as long as they have the same denominator!
So here's the big idea: fractions must have the same denominator.
If we multiply the first fraction by 2, then both fractions will have the same denominator. *
* Why 2??
- Because:
We need to find the least common multiple of 3 and 6, which is 6. Next, what should 3 be multiplied by to result in 6? That's right, 2.
Also, we can only multiply the denominator by 2 as long as we multiply the numerator by 2!
So that's why we multiply the whole fraction by 2

Drag each length to the correct location on the image. Each length can be used more than once, but not all lengths will be used.
What are the missing segment lengths shown in the image?
By applying Pythagoras theorem, the missing segment lengths of this triangles include:
CD = 10√2AC = 10√2BC = 10AB = 10How to find the missing segment lengths?Since triangle ACD is a right-angle triangle, we would use Pythagoras theorem to find the missing segment lengths of this triangles as follows:
c² = a² + b² ≡ AD² = CD² + AC²
Next, we would use cos trigonometric ratio to find side CD,
cos45 = adjacent/hypotenuse
cos 45 = CD/20
1/√2 = CD/20
CD = 1/√2 × 20
CD = (20√2)/2
CD = 10√2
For side AC, we have:
AD² = CD² + AC²
AC² = AD² - CD²
AC² = 20² - (10√2)²
AC² = 400 - 100(2)
AC = √200
AC = 10√2
From triangle ABC, we have:
cos45 = BC/10√2
BC = 10√2 × cos45
BC = 10√2 × 1/√2
BC = (10√2)/√2
BC = 10
For side AB, we have:
AB² = (10√2)² - 10²
AB² = 200 - 100
AB² = 100
AB = 10.

Select the correct answer.
Consider function g.
9(z) = 3 sin (TZ)
Function g is horizontally stretched by a factor of 2 and then translated 2 units down to obtain function f. Which graph matches the described
transformation?
The y-intercept exists reduced by 2 units. Hence there exists a translation of 2 units down.
How to find the graph of the given function?
Let the function be g(z) = 3 sin (TZ).
A vertical stretch by a factor of k indicates that the point (x, y) on the graph of f (x) exists transformed to the point (x, ky) on the graph of g(x), where k < 1.
If k = 1, then the same graph we get, and if k > 1 we get a vertically shrink graph.
In our question, there exists a vertical stretch of 2. This means the new graph would have points as (x, y/2)
i.e. instead of f(x) = y, we have now f(x) = y/2
So transformation is g(x) = 3f(x)
The y-intercept exists reduced by 2 units. Hence there exists a translation of 2 units down.
Therefore, the correct answer is option C.

What is the following simplified product? Assume x greater-than-or-equal-to 0 2 StartRoot 8 x cubed EndRoot (3 StartRoot 10 x Superscript 4 Baseline EndRoot minus x StartRoot 5 x squared EndRoot)
24 x cubed StartRoot 5 x EndRoot minus 4 x squared StartRoot 10 x EndRoot
24 x cubed StartRoot 5 x EndRoot minus 4 x cubed StartRoot 10 x EndRoot
24 x cubed StartRoot 5 EndRoot minus 4 x cubed StartRoot 10 x EndRoot
24 x cubed StartRoot 5 x EndRoot + 4 x cubed StartRoot 10 x EndRoot
The simplified expression of 2√8x³(3√10x⁴ - x√5x²) is 24x³√5x - 4x³√10x
How to determine the simplified product?The complete question is added as an attachment
From the attached figure, the product expression is:
2√8x³(3√10x⁴ - x√5x²)
Evaluate the exponents
2√8x³(3√10x⁴ - x√5x²) = 2 *2x√2x(3x²√10 - x²√5)
Evaluate the products
2√8x³(3√10x⁴ - x√5x²) = 4x√2x(3x²√10 - x²√5)
Open the bracket
2√8x³(3√10x⁴ - x√5x²) = 12x³√20x - 4x³√10x
Evaluate the exponents
2√8x³(3√10x⁴ - x√5x²) = 24x³√5x - 4x³√10x
Hence, the simplified expression of 2√8x³(3√10x⁴ - x√5x²) is 24x³√5x - 4x³√10x
