Answer: x= 12.4

Step-by-step explanation:

you should use trigonometry for this question, and you will have to follow tan to find the opposite side of the right-angled triangle.

tanθ = [tex]\frac{O}{A}[/tex]

tan(54°)= [tex]\frac{x}{9}[/tex]

tan(54)°x 9 = x (you should cross multiply)

x= 12.39

x= 12.4

The jam recipe that has more strawberry flavour would be recipe A with 1 cup of sugar to 6 cups of strawberries.

A recipe is defined as the a structured list that contains all the substances that are used for the preparation of a meal.

Strawberries = 3 cups

sugar = 1/2

Therefore 1 cup of sugar = 6 cups of strawberries

Strawberries = 5 cups

sugar = 1

Therefore 1 cup of sugar = 5 cups of strawberries

It can be concluded that jam recipe that has more strawberry flavour would be recipe A with 1 cup of sugar to 6 cups of strawberries.

The exact area of the circle is 4π [tex]units^2[/tex].

The center of the circle is at the origin (0,0)

The diameter of the circle = 4 units.

So, the radius of the circle = 2 units.

The circle passes through points (2,0) and (-2,0). The given points are on the x-axis and they are exactly 2 units away from the origin

The area of a circle  A = π [tex]r^2[/tex],

where A is the area, π is approximately 3.14 and r is the radius of the circle.

So, the area of the circle with a radius of 2 units is A = π [tex]r^2[/tex] = π([tex]2^2[/tex]) = 4π [tex]units^2[/tex]

One example of a function that is its own inverse is the square root function. The square root function takes a number and returns its inverse, which is always negative.

For example, the square root of 4 is equal to -2, and the square root of -3 is equal to 3. This means that you can multiply a number by -1 and then take the square root to get the same number as the original number. This proves that the inverse of a number is always a negative number. The opposite of a square is known as a rectangle. This shows that the square functions as its inverse. Another example of a function that is its own inverse is the exponential function. The exponential function takes two numbers and returns the reciprocal of their product. This means that the exponential function is also its own inverse because the reciprocal of a product is equal to the product of the reciprocals.

Answer: The formula for compound interest is A = P(1 + r/n)^(nt) where A is the amount, P is the principal (initial deposit), r is the interest rate, t is the time in years, and n is the number of times compounded per year.

To find out how many years it will take for the money to grow to 500 naira, we can set A equal to 500, P equal to 400, r equal to 5% (or 0.05), and n equal to 1 (since the interest is compounded annually).

Plugging these values into the formula, we get:

500 = 400(1 + 0.05)^t

By solving this equation, t = 3.32 years.

So, it will take 3.32 years for the money in the savings account to grow to 500 naira.

The multiplication functions are given as follows:

7) (f x g)(x) = 2x³ - 3x² - 21x - 18.

8) (f x g)(x) = (4)^x(2x + 8) - 10^x + 8.

The functions are multiplied first applying the associative property, multiplying all the terms among themselves, and then combining the like terms.

For item 7, the multiplication of the terms is given as follows:

(2x + 3)(x² - 3x - 6) = 2x³ - 6x² - 12x + 3x² - 9x - 18

Combining the like terms, the product is given as follows:

(2x + 3)(x² - 3x - 6) = 2x³ - 3x² - 21x - 18.

For item 8, the multiplication of the terms is given as follows:

(4^x - 5)(2x + 8) = 2x(4)^x + 8(4)^x - 10x + 8

One can solve basic algebraic expressions by following these steps.

In grade 6, students typically learn to solve basic algebraic expressions by following these steps:

Identify the variable and the coefficient (number in front of the variable) in the expression.

Use the order of operations (PEMDAS) to simplify any arithmetic within the expression.

Use the distributive property to combine like terms.

Isolate the variable on one side of the equation by using inverse operations (such as adding or subtracting the same value from both sides, or dividing or multiplying both sides by the same non-zero value).

Substitute in a value for the variable to find the numerical value of the expression.

It's good to practice with a lot of examples and check the solutions and ask for help if needed.

Example:

Solve for x: 3x + 2 = 12

variable is x, coefficient is 3

nothing to simplify

nothing to combine

subtract 2 from both sides: 3x = 10

divide both sides by 3: x = 10/3 or 3.3333

x = 3.3333

The statements that are true about the reflectional symmetry of a regular heptagon are:

A heptagon is a type of shape.

A two-dimensional shape having seven sides and seven angles is called a heptagon. It is a member of the two-dimensional geometry polygon class. Polygons are closed geometric shapes with only straight edges. In Greek, "hepta" denotes seven, while "gonia" denotes an angle.

A line of symmetry will connect a vertex and a midpoint of an opposite side.

It has 7-fold symmetry.

A regular heptagon has 7-fold symmetry, which means that it can be divided into 7 identical parts by rotating it by 360/7 = 51.43 degrees. Since it has 7 sides, a line of symmetry will connect a vertex and a midpoint of an opposite side.

It has only 1 line of symmetry, and a line of symmetry will not connect 2 vertices or the midpoints of 2 opposite sides.

Answer:

Step-by-step explanation:

The distance between the points (2, 0) and (-3, 2) = 5.4 units.

As we know according to the distance formula the distance between points (x₁, y₁) and (x₂, y₂) is given by,

[tex]d = \sqrt{[(x_2 - x_1)^2 + (y_2 - y_1)^2]}[/tex]

Here we have been given points (2, 0) and (-3, 2)

Let us assume that  (x₁, y₁) = (2, 0)

and (x₂, y₂) = (-3, 2)

Let d represents the distance between points (2, 0) and (-3, 2)

Using above distance formula the distance d between given points would be,

[tex]\Rightarrow d = \sqrt{[(x_2 - x_1)^2 + (y_2 - y_1)^2]}\\\\\Rightarrow d = \sqrt{[(-3 - 2)^2 + (2 - 0)^2]}\\\\\Rightarrow d = \sqrt{[(-5)^2 + (2)^2]}\\\\\Rightarrow d = \sqrt{25+4}\\\\\Rightarrow d = \sqrt{29}\\\\\Rightarrow d = 5.4~units[/tex]

Step-by-step explanation:

[tex]1^{2}[/tex] + 2 = 3

[tex]2^{2}[/tex] + 2 = 6

[tex]3^{2}[/tex] + 2 = 11

[tex]4^{2}[/tex] + 2 = 18

[tex]5^{2}[/tex] + 2 = 27

The linear equation that gives the rule for this table is y = 19x - 12.

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

The standard linear equation can be represented as:

y = mx + b

where, m is the slope and b is the y-intercept of the line.

From the table we can see the two points through which the point passes is:

(x1, y1) = (2, 26)

(x2, y2) = (3, 45)

The slope of the line is given by:

m = (y2 - y1) / (x2 - x1)

m = (45 - 26) / (3 - 2)

m = 19 / 1 = 19

The slope m = 19.

The point-slope form of the line can be written as:

y - y1 = m (x - x1)

y - 26 = 19 (x - 2)

y - 26 = 19x - 38

y = 19x - 38 + 26

y = 19x - 12

Hence, the linear equation that gives the rule for this table is y = 19x - 12.
