Final answer:

The slope for a line passing through two points can be found using the formula m = (y2 - y1) / (x2 - x1). By substituting the given points into the formula, the slope for the line passing through (1, 0.1) and (7, 26.8) is found to be 4.5.

Explanation:

The formula for the slope of a line passing through two points (x1, y1) and (x2, y2) is given by:

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

To find the slope for the given points (1, 0.1) and (7, 26.8), we can substitute the values into the formula:

m = (26.8 - 0.1) / (7 - 1) = 4.5

Therefore, the slope for the line passing through the given points is 4.5.

a. The equation for the line in point-slope form is [tex]\( y + 1 = \frac{5}{6}(x - 2) \).[/tex]

b. The equation in standard form is ( 5x - 6y = 16 ).

a. To find the equation of the line in point-slope form, we use the formula [tex]\(y - y_1 = m(x - x_1)\)[/tex], where (m) is the slope and [tex]\((x_1, y_1)\)[/tex] is a point on the line. Given the points (2, -1) and (8, 4), we can calculate the slope (m) as [tex]\(\frac{{y_2 - y_1}}{{x_2 - x_1}}\)[/tex]. Substituting the values, we get:

[tex]\[ m = \frac{{4 - (-1)}}{{8 - 2}} = \frac{5}{6} \][/tex]

Now, using the point-slope form, we substitute the values for (m) and [tex]\((x_1, y_1)\)[/tex]:

[tex]\[ y + 1 = \frac{5}{6}(x - 2) \][/tex]

b. To convert the equation to standard form, we want to eliminate fractions and express it as (Ax + By = C), where (A), (B), and (C) are integers. Multiply both sides of the equation by 6 to clear the fraction:

6(y + 1) = 5(x - 2)

Distribute the terms:

(6y + 6 = 5x - 10)

Bring all terms to one side:

[ 5x - 6y = 16 ]

So, the equation in standard form is (5x - 6y = 16). This form is preferred for certain applications, making it easier to identify coefficients and intercepts.

Final answer:

The company must sell either 2,000 or 5,000 items to break even, as determined by setting the profit function to zero and factoring the resulting quadratic equation.

Explanation:

To determine how many items must be sold for the company to break even, we need to set the profit function p(x) equal to zero and solve for x. In this case, the profit function is given by p(x) = -4x^2 + 28x - 40. Setting this to zero, we have:

-4x^2 + 28x - 40 = 0

Now, we need to solve this quadratic equation for x. To do this, we can factor the equation, use the quadratic formula, or complete the square. Since the coefficients are manageable, we'll try to factor first:

-4(x^2 - 7x + 10) = 0

Let's look for two numbers that multiply to 10 and add up to 7, which are 5 and 2. We can now factor further:

-4(x - 5)(x - 2) = 0

From the factored form, we get two potential solutions for x when the profit is zero:

x = 5

x = 2

Since x represents the number of items sold in thousands, the company must sell either 2,000 or 5,000 items to break even.

The weight of each tire in pounds is approximately:

Full steel bead tire: 1.76 pounds.

Lighter wheel: 1.54 pounds.

Given that the weight of a full steel bead tire is approximately 800 grams, while a lighter wheel weighs only 700 grams.

We need to convert the weights into pound.

To convert the weight of each tire from grams to pounds, we'll use the conversion factor that there are 453.592 grams in one pound.

Weight of a full steel bead tire in pounds:

800 grams x (1 pound / 453.592 grams) ≈ 1.76 pounds

Weight of a lighter wheel in pounds:

700 grams x (1 pound / 453.592 grams) ≈ 1.54 pounds

Rounded to 2 decimal places:

Weight of a full steel bead tire = 1.76 pounds

Weight of a lighter wheel = 1.54 pounds

2/9 divided by 5/12 simplifies to 2/15

Here we have to divide,

2/9 divided by 5/12

To divide fractions,

We have to flip the second fraction and multiply it by the first fraction. This gives us,

⇒ (2/9) ÷ (5/12) = (2/9) x (12/5)

We can simplify this expression by canceling out any common factors between the numerators and denominators.

In this case,

2 and 12 have a common factor of 2, while 9 and 5 don't have any common factors. This gives us,

⇒ (2/9) x (12/5) = 24/45

To express this fraction in its simplest form,

we can divide both the numerator and denominator by their greatest common factor, which in this case is 3.

This gives us,

6/45 = (24 ÷ 3) / (45 ÷ 3)

        = 8/15

Therefore, 2/9 divided by 5/12 simplifies to 8/15.

12) 10.77 + 2.09 + 0.75 = 13.61

13.61 x 1.07 = $14.56

 total amount = $14.56

14) C shows the possible combinations

Answer:

The correct option is B) $680.

Step-by-step explanation:

Consider the provided information.

Her total amount invested was $1,500. At the end of the year, she had earned $106.40 in interest.

Let she invested x amount with 8% interest rate.

Total amount she invested was $1,500, thus the amount she invested with 6% interest rate was 1500-x.

Total interest she earn was $106.40

Write this information into mathematical form.

[tex]x\times \frac{8}{100}+\frac{6}{100}(1500-x)=106.40[/tex]

[tex]x\times 0.08+0.06(1500-x)=106.40[/tex]

[tex]0.08x+90-0.06x=106.40[/tex]

[tex]0.08x-0.06x=106.40-90[/tex]

[tex]0.02x=16.4[/tex]

[tex]x=820[/tex]

Hence, she invested $820 with 8% interest rate.

The amount she invested with 6% interest rate was 1500-x.

Substitute the value of x in above.

1500-820=680

Hence, she invested $680 with 6% interest rate.

The correct option is B) $680.

The correct conversion from scientific notation to standard notation are:

            b)   [tex]8.05\times 10^5[/tex]

            e)   [tex]7.09\times 10^{-6}[/tex]

We know that when we have  a power of 10 as positive then the decimal is shifted to the right and if the power of 10 is negative then we shift the decimal to the left.

a)

         [tex]1.71\times 10^3[/tex]

As the power of 10 is positive hence we shift the decimal to the right 3 places.

Hence, the conversion is:

         [tex]1.71\times 10^3=1710[/tex]

b)

           [tex]8.05\times 10^5[/tex]

Again the power of 10 is positive and hence we will shift the decimal 5 places to the right and the conversion is done as follows:

        [tex]8.05\times 10^5=805000[/tex]

c)

       [tex]2.4\times 10^4[/tex]

Since, the power of 10 is positive and hence we will shift the decimal 4 places to the right and we convert the number to standard notation as:

      [tex]2.4\times 10^4=24000[/tex]

d)

           [tex]8.25\times 10^{-3}[/tex]

Since, the power of 10 is negative and hence we will shift the decimal 3 places to the left and we convert the number to standard notation as:

        [tex]8.25\times 10^{-3}=0.00825[/tex]

e)

             [tex]7.09\times 10^{-6}[/tex]

Since, the power of 10 is negative and hence we will shift the decimal 8 places to the left.

Hence, we convert our number to standard notation:

[tex]7.09\times 10^{-8}=0.00000709[/tex]

It is accurate to convert scientific notation to standard notation in the following ways:

B [tex]8.05x10^5=805,000[/tex]

Using the formula for compound interest, if you deposit $2,000 at 10% each year, the future balance in your account after 10 years would be approximately $5,187.12. This is due to the effect of compounding where the interest is calculated on both the principal and the accumulated interest.

The subject of this question is compound interest which is a Mathematics topic typically covered in High School. The formula A=p(1+r)^t is used to calculate the future balance in your savings account considering compound interest. Here, 'A' represents the future balance, 'p' is the current principle or balance, 'r' is the rate of interest, and 't' is time in years.

To answer your specific question: If you deposit $2,000 at a 10% rate each year, how much money will be in your account in 10 years? Let's plug the numbers into the formula. In this case, p=$2000, r=0.10 (as 10% equals 0.10 in decimal), and t=10 years.

So, A = 2000*(1 + 0.10)^10. Solving this, the future balance in your account after 10 years would be approximately $5,187.12. This is significantly more than simple interest ($100 × 0.05 × 3 = $15 in your example) due to the effect of compounding, as the interest is calculated on the principal plus the accumulated interest.
