Step-by-step explanation:

Answer:

The function is an exponential,

f(x) = A exp(log(3)x) = 2×3^x = 2(3)^x

The first point you graph for any exponential is (0,A), here (0,2). After (1,6), the next point might be (2,18).

Step-by-step explanation:

(0,2×3^0) = (0,2)

(1,2×3^1) = (1,6)

(2,2×3^2) = (2,2×9) = (2,18)

2(3)^x ought to be written 2×3^x, that is, two times three raised to the x power. x can be any real number.

Since 3 = exp(log(3)), we can substitute for 3 and write 2×exp(log(3))^x. Since exp(p)^q = exp(p×q), the function is also written 2×exp(log(3)x).

exp(x) is also written e^x. exp(x) is the unique function with exp(0)=1, and with the slope of the tangent line at exp(x) equal to exp(x). For instance, the slope at exp(0) is 1, the slope at exp(1) = e is e, slope at exp(2) is exp(2).

for A exp(b x), the slope at x is A b exp(b x).

For 3^x = exp(log(3)x), we have

3^0=1, slope log(3)

3^1=3, slope 3log(3),

3^2=9, slope 9log(3).

Step-by-step explanation: Put 2 as the exponent to get 3x3=9, then do 9x2=18. So x = 2 is y = 18 = (2,18).

Final answer:

To determine the sale price with a 65% markup on a skirt bought for $4.50, calculate the markup in dollars, add it to the original cost, and round to the nearest cent to get the final price of $7.43.

Explanation:

To find the sale price of the skirt after a markup of 65%, we first calculate the amount of the markup by multiplying the cost by the markup rate. The markup on the skirt that costs $4.50 would be:

$4.50 times 0.65 = $2.925.

Now, add the markup to the original cost to find the sale price:

$4.50(original cost) + $2.925(markup) = $7.425

However, prices are not typically listed with three decimal places, so we would round to the nearest cent, making the final sale price of the skirt $7.43.

Answer:

x = 4.057682724 pts

Step-by-step explanation:

A pint is equal to 473.176473 milliliters

473.176473 milliliters         1920 ml

-------------------------------   = -------------------------

1 pt                                        x pts

using cross products

473.176473  * x = 1902

 divide each side by 473.176473

x = 1920 /473.176473

x = 4.057682724 pts

U.S. liquid pint:

1 pint = 473.2 ml therefore 1 ml = 1/473.2 pints = 0.0021 pints.

1,920 ml = 1,920 · 0.0021 pints = 4.032 pints

U.S. dry pint:

1 pint = 550.6 ml therefore 1 ml = 1/550.6 pints = 0.0018 pints

1,920 ml = 1,920 · 0.0018 pints = 3.456 pints

The inequalities 12x + 4 > 16 and 3x - 5 < -14 simplify to x > 1 and x < -3 respectively. In graphical form, both inequalities represent lines extending from the points x = 1 and x = -3, with x > 1 going towards the right and x < -3 moving leftward.

To solve this inequality problem, we first isolate the variable on one side of the inequality for both expressions. Let's begin with 12x + 4 > 16. We can start by subtracting 4 from both sides to get 12x > 12, then divide each side by 12, resulting in x > 1.

Solve 12x + 4 > 16:

Subtract 4 from both sides to isolate 12x:

12x > 16 - 4

12x > 12

Divide both sides by 12:

x > 1

Solve 3x - 5 < -14:

Add 5 to both sides to isolate 3x:

3x < -14 + 5

3x < -9

Divide both sides by 3:

x < -3

Now, you have two separate solutions:

For the first inequality, x > 1.

For the second inequality, x < -3.

This means the solution graph includes all values of x that are greater than 1 or less than -3. In graphical terms, it's the union of two intervals:

Solution Graph: (-∞, -3) ∪ (1, ∞)

This represents all real numbers less than -3 and all real numbers greater than 1.

For a cleaning solution with a ratio of 4 cups of baking soda to 3 cups of water, each cup of water would require approximately 1.33 cups of baking soda. Hence, the correct answer is B) 4/3.

Alice's cleaning solution uses a ratio of 4 cups of baking soda to 3 cups of water. This ratio can be expressed as a fraction, 4/3. To find out how much baking soda is needed for each cup of water, we need to simplify this ratio. In other words, we divide the number of cups of baking soda by the number of cups of water.

When we divide 4 by 3, we get 1.33 (repeating). That means, for each cup of water, Alice will need approximately 1.33 cups of baking soda. So, the answer is B) 4/3.

Answer:

Number 95 is bigger than number 85.

Step-by-step explanation:

If we want to find which number is the bigger one; we subtract the numbers in  two orders:

95 - 85 = 10

and

85 - 95 = -10

Since the first order (95 - 85) gives a positive answer;

Then it implies that number 95 is bigger than number 85.

Since the second order (85 - 95) gives a negative answer;

Then it implies that number 85 is smaller than number 95.

Answer:

The equation would be y = 8x - 38

Step-by-step explanation:

To find the equation of this new line, we first need to identify the slope of the first line. In slope-intercept form, the slope is always the coefficient of x. This makes the slope of the first equation 8. Since parallel lines have the same slope, our new slope will also be 8.

Given that and the point, we can solve for the equation using point-slope form.

y - y1 = m(x - x1)

y - 2 = 8(x - 5)

y - 2 = 8x - 40

y = 8x - 38

The equation of the line in point slope form is y = 8x - 38

The formula for calculating the equation of a line in point slope form is expressed as:

[tex]y-y_0=m(x-x_0)[/tex]

Given the equation of a line as y = 8x - 8

Slope m = 8

Point = (5, 2)

Get the required equation in point slope form as shown:

[tex]y-2=8(x-5)\\y-2 = 8x - 40\\y = 8x - 40 + 2\\y =8x-38[/tex]

Hence the equation of the line in point slope form is y = 8x - 38

Step-by-step explanation:

The pair of polygons in the image are not similar. Although they are both rectangles, they do not have the same corresponding side ratios.

A rectangle is defined by having four right angles and two pairs of parallel sides. The corresponding sides of similar rectangles are in proportion. In the image, the rectangle on the left has side lengths of 11 ft and 10 ft, while the rectangle on the right has side lengths of 9.4 ft and 8.4 ft.

The ratio of the corresponding sides is not the same for both pairs of sides. The ratio of the left side lengths is 11 ft / 9.4 ft, which is about 1.17. The ratio of the right side lengths is 10 ft / 8.4 ft, which is about 1.19. Because the corresponding side ratios are not the same, the rectangles are not similar.
