Round your answer to the nearest hundredth.

Answer:

Step-by-step explanation:

P = efe =4.8

f =0.26

substitute the value of P and f into the equation to obtain the value of e

4.8 = e*0.26*e

4.8 = 0.26*e^2

make e^2 the subject of the formula

e^2 =4.8/0.26 =18.62

find the square root of e

e =\(\sqrt{x} 18.46\\\)

e = 4.3

Lower bound of P = 4.8 - 4.79 = 0.01

Answer:

x ≈ 2.76

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan78° = \(\frac{opposite}{adjacent}\) = \(\frac{AB}{BC}\) = \(\frac{13}{x}\) ( multiply both sides by x )

x × tan78° = 13 ( divide both sides by tan78° )

x = \(\frac{13}{tan78}\) ≈ 2.76 ( to 2 dec. places )

B. 2 and OD. 15 are not possible lengths for the third side of the triangle.

To determine the possible values for the length of the third side of a triangle, we need to consider the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Given that two sides have lengths 6 and 9, we can analyze the possibilities:

6 + 9 > x

x > 15 - The sum of the two known sides is greater than any possible third side.

6 + x > 9

x > 3 - The length of the unknown side must be greater than the difference between the two known sides.

9 + x > 6

x > -3 - Since the length of a side cannot be negative, this inequality is always satisfied.

Based on the analysis, the possible values for the length of the third side are:

A. 7

C. 4

□E. 10

O F. 12

B. 2 and OD. 15 are not possible lengths for the third side of the triangle.

Answer:

Step-by-step explanation:

(1) T(x, y) = (x+3, y-2)

going to the right is x directions and that right means it's +

going down means y direction and down means -

(2) F(x,y) = (-x, y)

When a point goes across the y-axis only x changes

(3) R(x,y) = (-y,x)

When you draw the point to origin and rotate that point 90 degrees

(B)  In algebra you have something that is unsolved and you use equations that describe lines.  For part A, you are using a cartesian plane and are moving your points around.

(C)For S(x,y)

First R(x,y)= (-x,-y)                 >This is rotation 180°

Then T(-x, -y) = (-x-6, -y)         >This is for 6 left

Last F(-x-6, -y) = (-y, -x-6)            >this is for reflection over y=x

S(x,y) = = (-y, -x-6)

Answer:

\(\textsf{A-1)} \quad T(x, y)=(x+3,y-2)\)

\(\textsf{A-2)} \quad F(x, y) = (-x, y)\)

\(\textsf{A-3)} \quad R(x, y) = (-y,x)\)

\(\textsf{B)}\quad \rm See\; below.\)

\(\textsf{C)} \quad S(x,y)=(-y, -x - 6)\)

Step-by-step explanation:

When a point (x, y) is translated n units right, we add n to the x-value.

When a point (x, y) is translated n units down, we subtract n from the y-value.

Therefore, the function to represent the point (x, y) being translated 3 units right and 2 units down is:

\(\boxed{T(x, y)=(x+3,y-2)}\)

\(\hrulefill\)

When a point (x, y) is reflected across the y-axis, the y-coordinate remain the same, but the x-coordinate is negated.

Therefore, the mapping rule for this transformation is:

\(\boxed{F(x, y) = (-x, y)}\)

\(\hrulefill\)

When a point (x, y) is rotated 90° counterclockwise about the origin (0, 0), swap the roles of the x and y coordinates while negating the new x-coordinate.

Therefore, the mapping rule for this transformation is:

\(\boxed{R(x, y) = (-y,x)}\)

\(\hrulefill\)

Functions that work with Cartesian points (x, y), such as f(x, y), are different from algebraic functions, like f(x), because they accept two input values (x and y) instead of just one, and produce an output based on their relationship.

While functions such as f(x) deal with one variable at a time, functions with two variables allow for more complex mappings and transformations in two-dimensional Cartesian coordinate systems. They are useful when you need to figure out how points relate to each other in a two-dimensional space.

\(\hrulefill\)

To write a function S to represent the sequence of transformations applied to the point (x, y), we need to consider each transformation separately.

The first transformation is a rotation of 180° clockwise about the origin.

If point (x, y) is rotated 180° clockwise about the origin, the new coordinates of the point become (-x, -y).

Therefore, the coordinates of the point after the first transformation are:

The second transformation is a translation of 6 units left.

If a point is translated 6 units to the left, subtract 6 from its x-coordinate.

Therefore, the coordinates of the point after the second transformation are:

Finally, the third transformation is a reflection across the line y = x.  

To reflect a point across the line y = x, swap its x and y coordinates.

Therefore, the coordinates of the point after the third transformation are:

Therefore, the mapping rule for the sequence of transformations is:

\(\boxed{S(x, y) =(-y, -x - 6)}\)

Answer: x= 1, 5

Step-by-step explanation:

First, isolate the absolute value. Subtract two from the equation to get -l3x-9l=-6, and then divide by -1 to get l3x-9l=6.

Since an absolute value measures how far away a value is from zero, it's always positive. For example, -10 and 10 have the same absolute value, 10, because they're both 10 units away from zero.

Because of this, you create two equations; 3x-9=6, and 3x-9=-6.

For the first equation, add 9 to 6 and divide that by 3 to get x=5.

For the second equation, add 9 to -6 and divide that by 5 to get x=1.

The value of f[g(x)] is - 64x³ - 336x² - 588x - 340 and the value of g[f(x)] is -4x³ + 19

The functions are as follows; f(x) = -x³ +3 and g(x) = 4x+7

The value of f[g(x)] is obtained by replacing every x in f(x) with the value of g(x) as given below

f[g(x)] = f(4x + 7) = - (4x + 7)³ + 3

When we expand (4x + 7)³, it gives us 64x³ + 336x² + 588x + 343

Then

f[g(x)] = - 64x³ - 336x² - 588x - 340

Similarly, g[f(x)] is obtained by replacing every x in g(x) with the value of f(x) as shown below;

g[f(x)] = g(-x³ + 3) = 4(-x³ + 3) + 7g

[f(x)] = -4x³ + 19

Therefore,

f[g(x)] = - 64x³ - 336x² - 588x - 340

By using the concept of simple interest, it can be calculated that

Brionny has invested £8400.

What is simple interest?

Simple interest is the interest earned on a certain principal at a certain rate over a certain period of time

For the first year-

Principal = £P

Rate = 2%

Time = 1 year

Interest = \(\frac{P \times 2 \times 1}{100}\) =  £\(\frac{P}{50}\)

Amount = £\((P + \frac{P}{50})\)

             = £\((\frac{50P + P}{50})\)

             = £\(\frac{51P}{50}\)

For the Second year:

Principal =  £\(\frac{51P}{50}\)

Rate = 1%

Time = 1 year

Interest = \(\frac{51P \times 1 \times 1}{50 \times 100}\) =  £\(\frac{51P}{5000}\)

Amount = £\((\frac{51P}{50} + \frac{51P}{5000})\)

             = £\((\frac{5100P + 51P}{5000})\)

             = £\(\frac{5151P}{5000}\)

By the problem,

\(\frac{5151P}{5000} = 8653.68\\P = \frac{8653.68 \times 5000}{5100}\\\)

The exact value of tan(2arcsin(x)) is 2x / √(1 - x²), where |x| ≤ 1.

To find the exact value of tan(2arcsin(x)), we start by considering the definition of arcsin. Let θ = arcsin(x), where |x| ≤ 1. From the definition, we have sin(θ) = x.

Using the double angle identity for tangent, we have tan(2θ) = 2tan(θ) / (1 - tan²(θ)). Substituting θ = arcsin(x), we obtain tan(2arcsin(x)) = 2tan(arcsin(x)) / (1 - tan²(arcsin(x))).

Since sin(θ) = x, we can use the Pythagorean identity sin²(θ) + cos²(θ) = 1 to find cos(θ). Taking the square root of both sides, we have cos(θ) = √(1 - sin²(θ)) = √(1 - x²).

Now, we can determine the value of tan(arcsin(x)) using the definition of tangent. We know that tan(θ) = sin(θ) / cos(θ). Substituting sin(θ) = x and cos(θ) = √(1 - x²), we get tan(arcsin(x)) = x / √(1 - x²).

Finally, substituting this value into the expression for tan(2arcsin(x)), we obtain tan(2arcsin(x)) = 2x / (1 - x²).

Therefore, the exact value of tan(2arcsin(x)) is 2x / √(1 - x²), where |x| ≤ 1.

Let the height be y as well as the side length of a square base be x. The rectangular solid's surface area is then determined by:

When we simplify this equation, we obtain:

The rectangular solid's volume is determined by:

V = x² × y = x² × (433.5 - 4x²) / (2x)

When we simplify this equation, we obtain:

V = 216.75x - 2x³

We must determine the value of x that maximizes V in order to determine the dimensions that lead to a solid with the maximum volume. Using V's derivative with x as the base, we can calculate:

dV/dx = 216.75 - 6x²

By setting this to 0 and figuring out x, we obtain:

216.75 - 6x² = 0

x² = 36.125

x ≈ 6.005

When we rewrite the equation for y using this value of x, we obtain:
