C + A = 33    (even if all were the higher paying  adults, that would only be 33x2.25=74.25  far less than <<786.75)

A polynomial function that has zeros,

5 and -2+2i, is x² -x(3 +2i) +10(i - 1).

An expression that consists of variables, constants, and exponents that are combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial.

Given:

A polynomial function has zeros,

5 and -2+2i.

Firstly, we will write the zeros as factors of the polynomial,

(x-5) and (x +2 - 2i).

Now, multiply the factors,

⇒ x²+2x -2ix -5x -10 + 10i

⇒ x² -x(3 +2i) +10(i - 1)

Therefore, x² -x(3 +2i) +10(i - 1) is the required polynomial.

Answer:

Step-by-step explanation:From the issue, we may deduce that:

x + y = 50 She desires to produce 50 ounces of the combination (because to this).

(0.35x) + (0.60y) = 0.55(x+y) (because we're calculating the amount of salt in each solution and the combination contains 55% salt)

We may take the first equation and replace it in the second equation:

(0.35x) + (0.60y) = 0.55(50) (50)

0.35x + 0.60y = 27.5 when x is substituted.

A system of two equations with two variables is now available:

x + y = 50\s0.35x + 0.60y = 27.5

To determine one of the variables in terms of the other, we may utilize the first equation. Let's figure out y:

y = 50 - x

We now change y in the second equation to the following expression:

0.35x + 0.60(50-x) = 27.5

Finding the value of x:

0.35x + 30 - 0.6x = 27.5

0.25x= -2.5

x= -10

Since the number of ounces cannot be negative, the answer is illogical. As a result, you should double-check your calculations or determine if the issue statement contains a mistake.

To get the answer, you can also try an alternative approach like substitution or elimination. Then, double-check your calculations.

The given expression is not an equivalent expression.

What is an equivalent expression?

An equivalent expression is a mathematical expression that has the same value as another expression, even though they may appear to be different. Equivalent expressions are obtained by using the same operations or by making substitutions that preserve the value of the expression.

The expressions -6z + (-5.5) and 3.5z - 5y - 2.5 are not equivalent. They have different coefficients for the variables z and y, and different constants. To determine if two expressions are equivalent, you need to check that they have the same value for all possible values of the variables. If the values are the same for all inputs, then the expressions are equivalent. If the values are not the same for all inputs, then the expressions are not equivalent.

Hence, the given expression is not an equivalent expression.

The difference between the largest 5-digit number and the smallest 6-digit number is 1.

The aim is to find the largest 5-digit and the smallest 6-digit numbers, and then we need to identify the difference between these two values.

Let's start by finding the smallest 6-digit number.

We know that 0 is the smallest digit that can not be used in the highest place value, so we will consider the next smallest digit; that is, 1 and 1 can be used in the highest place value.

Thus, we can create the required 6-digit smallest number with 0 and 1.

Hence, the smallest 6-digit number is 100000.

Now, we will discover the largest 5-digit number.

As we know, the largest digit is 9, which can be used anywhere. So, we will form the largest 5-digit number with the digit 9.

Thus, the largest 5-digit number is 99999.

Next, we need to find the difference between these two values.

So, we can determine the difference between the smallest 6-digit number and the largest 5-digit number by subtracting the smallest from the largest.

Thus, we get,

⇒100000 - 999999

⇒1

Hence, 1 is the difference between the smallest 6-digit and the largest 5-digit numbers.

The length of TS  in ΔTRS using Similarity of triange is 12 cm .

If two items have the same shape or have the same shape as their mirror images, they are said to be Similar. One can be produced from the other more accurately by evenly scaling it, perhaps with the addition of further translation, rotation, and reflection.

If the sides are in the same ratio or proportion and the angles are equal (corresponding angles), two triangles will be comparable (corresponding sides). Similar triangles may have varying individual side lengths, but they must have equal angles and the same scale factor or matching ratio of the side lengths. If two triangles resemble one another, then

To find the sine of an angle in a right triangle, we can use the following relationship:

[tex]sin(angle) = opposite side / hypotenuse\\[/tex]

What is right triangle?

A right triangle is a type of triangle that has one angle that measures exactly 90 degrees (also known as a right angle). This angle is formed by the intersection of two legs of the triangle, which are not the hypotenuse of the triangle. The side opposite the right angle is called the hypotenuse and it is always the longest side of the triangle.

To find the sine of an angle in a right triangle, you can use the following relationship:

[tex]sin(angle) = opposite side / hypotenuse\\[/tex]

This relationship holds true for any angle in a right triangle, not just the acute angles.

For example, if you have a right triangle with an angle of 30 degrees and the opposite side is 5 units and the hypotenuse is 12 units, you can find the sine of the angle by dividing the opposite side by the hypotenuse:

[tex]sin(30) = 5/12 = 0.4166\\[/tex]

It's also important to note that the sine of an angle is always between -1 and 1, and the sine of an acute angle is always positive.

Mixed fractions are type of fractions which consist of a whole number part and a fractional part.

Mixed fractions are of the form a b/c where a is the whole number part and b/c is the fractional part.

Given that,

Area of the patio = 2 1/4 square yards

The complete question is as follows :

A patio has an area of 2 1/4 square yards. 3/4 of the patio is carpeted. What is the area of the carpeted part of the patio?

Correct option is A,  f(x) -2 has changed the parent function f(x) = (0.5)x to its new appearance.

The parent function f(x) = log5x has been modified by reflecting it over the x-axis, extending it vertically by a factor of three, and moving it down by three units.

In the picture below you can see the blue line is the graph of the function

f(x) = log(5x) and the green line is the graph of the function

g(x) = log[5(x + 4)] - 2

Since the function f passes at point (2, 1), we must reduce it by 2 units to ensure that it also passes at position (-2, -1). To do this, we add 2 to the function f.

We only need to add 4 to the variable x to have the function go left when we obtain log(5x) - 2.

The function shifts to the left when you add a number to x;

The function moves to the right when you remove a number from x;

The function increases when you add a number to it;

The function decreases when you take a number away from it.

Then we get a function g(x) = log[5 (x + 4)] - 2.

The slope and y-intercept of the linear function y = -10x + 1 are -10 and (0,1) respectively.

The given linear function is y = -10x + 1.

The slope of a linear function is the coefficient of the x-term. In this case, the slope is -10.

The y-intercept of a linear function is the point at which the line crosses the y-axis. To find the y-intercept, we can substitute x = 0 into the equation and solve for y.

y = -10(0) + 1

y = 1

So, the y-intercept is (0,1).

Therefore, the slope and y-intercept of the linear function y = -10x + 1 are -10 and (0,1) respectively.

What is axis ?

An axis is a straight line around which an object or a geometric shape can rotate or be symmetrical. In a coordinate system, an axis is a line that serves as a reference for the location of points in space.

When a function f(x) is reflected over the x-axis, it changes the sign of the y-coordinate values. By reflecting the graph of f(x) over the x-axis, the new function g(x) will have the same shape as f(x) but with all y-coordinate values inverted.

Additionally, by shifting the function up 3 units, it means that the y-coordinate values of the new function g(x) will be 3 units greater than the y-coordinate values of the original function f(x).

So the transformation can be represented as:

g(x) = f(x-1) + 4

It is the horizontal shift of 1 unit to the right, and a vertical shift of 3 units up
