The money that she earns in total, after paying the vendor fees and repaying her brother's loan is $95.

From the information, Mia borrowed $800 from her brother to start a small business and she then applies to sell her products at a vendor fair.

Also, it should be noted that the vendor fair requires all businesses to pay a $50 entry fee, plus 10% of their sales.

The amount that she will earn after selling $1050. worth of product will be;

= $1050 - Amount borrowed - Entry fee - Percentage on sales

= $1050 - ($800) - $50 - (10% × $1050)

= $1050 - $800 - $50 - $105

= $95

300 milligrams is 0.3 grams of protein.

A conversion factor is a number that is used to multiply or divide one set of units into another. If a conversion is required, it must be done using the correct conversion factor to get an identical value. For instance, 12 inches equals one foot when converting between inches and feet.

To convert a value or expression between two different forms. • Measurement: converting between different units, for as from inches to millimeters or liters to gallons. For instance, change 12 inches to millimeters. 304.8 millimeters are equal to 12 inches multiplied by the inch-to-millimeter ratio of 25.4.

Given Data

100 grams of honey  contains about 0.3 grams of protein.

1 gram = 1000 milligrams

To find milligrams in protein:

0.3 grams multiplied by 1000

0.3(1000)

By evaluating the function f(x) = x² - 5 · x, the range of the function is {- 6, - 4, 14}.

In this problem we have a domain, that is, an input set, formed by three natural numbers and a quadratic equation that represents a function that allows us to find the corresponding elements of the range, that is, the output set. The elements of the range are found by evaluating the quadratic equation at each element from domain:

A scatter plot which best represents the data in the table is scatter plot B.

A scatter plot is also referred to as scatter chart, scatter diagram or scattergram and it can be defined as a type of graph which is used for the graphical representation of the values of two (2) variables, with the resulting points showing any association (correlation) between the data set.

In this scenario, the altitude (thousand feet) would be plotted on the x-axis of the scatter plot while the air pressure (pounds per square inch) would be plotted y-axis of the scatter plot as depicted in the image attached below.

In conclusion, we can reasonably infer and logically deduce that scatter plot B best represents the data in the table.

Answer:

220 meters

Step-by-step explanation:

20 seconds is 5 times larger than 4 seconds, so the distance it runs in 20 seconds should be 5 times longer than 44 meters
so:
20/4 = 5
since x is 5 times larger than 44, set up the equation
5 = x/44
multiply both sides by 44
x= 44 * 5 = 220 meters

The number of cups of sugar that is required to make 16 pies is equal to 8 cups.

Mathematically, a direct proportion can be represented the following mathematical expression:

y = kx

Where:

Since the cups of sugar varies directly (direct proportion) with the number of pies, the cups of sugar and number of pies must remain in a constant ratio.

Next, we would determine the constant of proportionality (k) as follows:

Constant of proportionality (k) = y/x

Constant of proportionality (k) = (1 1/2)/3

Constant of proportionality (k) = 0.5 or 1/2

From the above mathematical expression for direct proportion, an equation which models the situation or relationship is:

y = kx

y = 0.5x

Now, we can determine the number of cups of sugar at x = 16:

y = 0.5 × 16

y = 8 cups of sugar.

The value of the quotient is 1.207

The statement is given as

Divide 306.67 and 254.00

Rewrite the above statement properly

So, we have

Divide 306.67 by 254.00

Rewrite the above statement as a quotient expression

So, we have

306.67/254.00

Express 306.67 as 254.00 + 52.67

So, we have

306.67/254.00 = (254.00 + 52.67)/254.00

Evaluate the quotient of 254 and 254

So, we have

306.67/254.00 = 1 + 52.67/254.00

Evaluate the other quotient

So, we have

306.67/254.00 = 1 + 0.207

306.67/254.00 = 1.207

When working with unknowable numbers, we can simplify equations by using the distributive property. If the equation be 10x² - (9x + 4x²) + 7 + (5x - 8) then we get 6x² - 4x - 1.

The distributive property of binary operations in mathematics generalizes the distributive law, which states that in elementary algebra, equality is always true.

Let the equation be 10x² - (9x + 4x²) + 7 + (5x - 8)

Apply rule: a +(b + c) = a + b + c

7 + (5x - 8) = 7 + 5x - 8

= 10 x²- (9 x + 4 x²) + 7 + 5x - 8

simplifying the above equation, we get

= -(9x + 4x²) + 10x² + 5x + 7 - 8

Subtract the numbers: 7 - 8 = -1

= -(9x + 4x²) + 10x² + 5x - 1

Apply the distributive law: -(a + b) = -a - b = 0

-(9x + 4x²) = - 9x - 4x²

= -9x - 4x² + 10x² + 5x - 1

Add similar elements:

-4x² + 10x² = 6x² = -9x + 6x² + 5x - 1

simplifying the above equation, we get

= 6x² - 9x + 5x - 1

Add similar elements: -9x + 5x = -4x

= 6x² - 4x - 1

Therefore, by simplifying the equation, we get 6x² - 4x - 1.

[tex]f(x)=3x^4+51x^2+48[/tex]

Step-by-step explanation:

As n = 4, the degree of the polynomial is 4.

Therefore, the function cannot have more than 4 distinct roots.

[tex]\implies f(x)=a(x-p)(x-q)(x-r)(x-s)[/tex]

If a complex number z is a root of f(z) = 0 then its complex conjugate is also a root.  Therefore:

[tex]\implies f(x)=a(x-i)(x+i)(x-4i)(x+4i)[/tex]

[tex]\implies f(x)=a(x^2-i^2)(x^2-16i^2)[/tex]

[tex]\implies f(x)=a(x^2-(-1))(x^2-16(-1))[/tex]

[tex]\implies f(x)=a(x^2+1)(x^2+16)[/tex]

Given f(-1) = 102, then:

[tex]\begin{aligned}\implies f(-1)=a((-1)^2+1)((-1)^2+16)&=102\\a(1+1)(1+16)&=102\\a(2)(17)&=102\\34a&=102\\a&=3\end{aligned}[/tex]

Therefore:

[tex]\implies f(x)=3(x^2+1)(x^2+16)[/tex]

[tex]\implies f(x)=3(x^4+17x^2+16)[/tex]

We can show z = 1 ± i satisfies the equation [tex]z^2-2z+2=0[/tex] by putting the values of z in the given equation.

z = 1 ± i

Equation:

[tex]z^2-2z+2=0[/tex]

We have to show that z satisfies the given equation.

Complex numbers

A complex number is an element of a number system that extends the real numbers with a specific element denoted i, called the imaginary unit and satisfying the equation [tex]i^2 = -1[/tex]; every complex number can be expressed in the form a + bi, where a and b are real numbers.

Putting z = 1 + i in the given equation, we get

[tex](1+i)^2-2(1+i)+2 = 1 + i^2+2i -2-2i+2[/tex]

= (1 - 1 -2 +2) + (2i - 2i)  

= 0 + 0 = 0

Putting z = 1 - i in the given equation, we get

[tex](1-i)^2-2(1-i)+2 = 1 + i^2-2i -2+2i+2[/tex]

= ( 1 - 1 - 2 + 2) + (-2i+2i)

= 0 + 0 = 0

As we can see that putting z = 1 ± i  in the given equation, we get 0, hence, we have shown that z satisfies the given equation.
