Write the equation of a line that is perpendicular to y= 3/2x - 4 and goes through the points (2,-2)

Let's call the tens digit "x" and the units digit "y". We know that the number is a multiple of 9, so:

x + y = 9

and the ratio of the units digit to the tens digit is 1:2, so:

y = 2x

Substituting the second equation into the first, we get:

x + 2x = 9

3x = 9

x = 3

So the tens digit is 3 and the units digit is 2 times that, or 6. The number is 36.

Answer:

63

Step-by-step explanation:

___________________

First, let's list all the 2-digit multiples of "9":

______________________________________________________

18, 27, 36, 45, 54, 63, 72, 81, 90, 99.

______________________________________________________

From this list, the only answer that has a ratio in which its "units digits to its tens digits" is "1:2" is: "63" . "3:6" = "1:2" .

The final price of Thomas Peters' new SUV  is $30,309 , can be calculated by subtracting the rebates from the initial cost.

The initial cost of the SUV was $32,984, and he received a $2,175 rebate from the car dealer and a $500 rebate from the manufacturer. So, the final price would be calculated as follows:

Final Price = $32,984 - $2,175 - $500

Final Price = $30,309

Therefore, the final price of Thomas Peters' new SUV is $30,309.

It is important to note that rebates can play a significant role in reducing the cost of a car purchase. In this case, Thomas Peters was able to receive a total of $2,675 in rebates, which reduced the cost of his new SUV by over 8%. This shows that it is often worth the time and effort to research available rebates and incentives when making a car purchase. Additionally, it is also a good idea to negotiate the price with the car dealer, as there may be room for further discounts.

By taking these steps, you may be able to save a significant amount of money on your car purchase and get a better value for your money. Ultimately, it is important to weigh the cost and benefits of each car option to determine the best choice for your needs and budget.

Step-by-step explanation:

Answer:

The simplified expression is a^(21/20).

Step-by-step explanation:

To simplify the expression, we can use the rule for multiplying two powers with the same base, which is to add the exponents.

a^(3/5) * a^(3/4) = a^(3/5 + 3/4) = a^(6/5 + 3/4)

We can then simplify the fractional exponent by finding a common denominator for the numerators, which is 20 in this case:

a^(6/5 + 3/4) = a^(6/20 + 15/20) = a^(21/20)

The simplified expression is a^(21/20).

Answer:

Step-by-step explanation:

Since the polynomial has a root of multiplicity 2 at x = 3, it can be written as (x - 3)^2 times another polynomial Q(x). Also, since it has roots of multiplicity 1 at x = 0 and x = -4, it can be written as (x - 3)^2 * (x - 0) * (x + 4) * Q(x).

Next, we can use the fact that the polynomial goes through the point (5, 144) to find the formula for Q(x). The polynomial P(x) must satisfy P(5) = 144, so we can write:

(5 - 3)^2 * (5 - 0) * (5 + 4) * Q(5) = 144

4 * 9 * 9 * Q(5) = 144

36 * Q(5) = 144

Q(5) = 4

So, the polynomial P(x) can be written as:

P(x) = (x - 3)^2 * (x - 0) * (x + 4) * 4

  = 4 * (x - 3)^2 * (x - 0) * (x + 4)

  = 4 * (x^2 - 6x + 9) * x * (x + 4)

  = 4x^4 - 84x^3 + 378x^2 - 648x + 576

This is the formula for P(x).

What are trigonometric ratios?

Trigonometric ratios are ratios of the sides of a right triangle that are used to define the relationships between the angles and the sides of the triangle. The three basic trigonometric ratios are sine, cosine, and tangent, which are commonly abbreviated as sin, cos, and tan, respectively.

The expression (sin 3x)(cos x) − (cos 3x)(sin x) is an example of a trigonometric identity known as the "sin of a difference" formula:

sin(A - B) = sin A cos B - cos A sin B

By comparing this formula to the given expression, we can see that:

A = 3x

B = x

Substituting these values into the formula, we get:

sin(3x - x) = sin 2x = (sin 3x)(cos x) − (cos 3x)(sin x)

Answer:

Both of them are correct.

Step-by-step explanation:

Let's review both of their methods and check their validity.

This method is the most straight forward and seems to be correct as we're simply calculating the total value of each, and then subtracting the difference. We can write the expression as: [tex]2.25(4.25)-2.25(2.85)[/tex] and this should give us the difference assuming the prices and math is done correctly.

While this method is a bit difference, it actually does work! Think of this way, we first calculate the difference in the prices and then for each pound we increase it by, the difference also increases by this amount. It also helps to look at our original expression: [tex]2.25(4.25)-2.25(2.85)[/tex], notice how we have a factor of 2.25 on both sides? Well we can just factor that out to get: [tex]2.25(4.25 - 2.85)[/tex] and this is essentially what Ariel's method is. This should give us the difference in prices and is likely easier than Kaylee's method as we do less multiplication and with smaller numbers.

The dimensions of the sticker are 11 millimeters and 3 millimeters.

Area of a two dimensional shape is the total region which is bounded by the object's shape.

Perimeter of a straight sided figures or objects is the total length of it's boundary.

Given is a sticker which is rectangular in shape.

Area of the sticker = 33 millimeters²

Perimeter of the sticker = 28 millimeters

Area of a rectangle = Length × Width

Perimeter of a rectangle = 2(Length + Width)

Let x be the length and y be the width of the rectangle.

x y = 33

2(x + y) = 28 ⇒ 2x + 2y = 28 ⇒ 2y = 28 - 2x ⇒ y = 14 - x

Substituting y = 14 - x in x y = 33,

x(14 - x) = 33

14x - x² = 33

-x² + 14x - 33 = 0

x² - 14x + 33 = 0

Factorizing the quadratic equation,

(x - 11) (x - 3) = 0

x - 11 = 0 or x - 3 = 0

x = 11 or x = 3

If x = 11, then y = 33/11 = 3

If x = 3, y = 33/3 = 11

Answer:

Step-by-step explanation:

o find F'(4), we need to use the chain rule of differentiation. The chain rule states that if F(x) = f(g(x)), then F'(x) = f'(g(x)) * g'(x).

Given that f(-2) = 5, f'(-2) = 9, f'(4) = 3, g(4) = -2, and g'(4) = 4, we can calculate F'(4) as follows:

F'(4) = f'(g(4)) * g'(4) = f'(-2) * g'(4) = 9 * 4 = 36

Therefore, F'(4) = 36.

Jade and Juliette 44.7days  more days to complete their trip.

To calculate how many more days Jade and Juliette need to ride, we can use the equation:

Total distance = Distance on first day + Distance on second day + Distance on remaining days

We know the first and second day distances, and the daily distance for the remaining days, so we can substitute those values in the equation:

2878 = 45.4 + 56.3 + 62x

where x is the number of remaining days they need to ride.

Simplifying the equation:

2878 - 101.7 = 62x

2776.3 = 62x

Dividing both sides of the equation by 62

x = 44.7

hence, Jade and Juliette need to ride for 44.7 more days to complete their trip.

The chances are that your gain will be $40 if you purchase two shares of ABC stock and no shares of XYZ stock, and if it is not $40 the gain is:

1) 50%, $0

2) 25%, $20

3) 75%, $30

4) 50%, $20

So, the option (4) 50%, $20 is the correct option.

The given question is asking what the chances are that your gain will be $40 if you purchase two shares of ABC stock and no shares of XYZ stock, and what the gain will be if it is not $40.

Mathematically, this can be broken down as follows:

There is a 50% chance that the temperature will be lower than average, in which case the stock price for ABC will increase by $20. Thus, the expected gain from investing in ABC is 50% x $20 = $10.

There is a 25% chance that the temperature will be higher than average, in which case the stock price for XYZ will increase by $20. Since you are not investing in XYZ, your expected gain from this is 0.

Therefore, the expected gain from investing in ABC and not investing in XYZ is 50% x $10 + 25% x $0 = $10 + $0 = $10.

Since you are investing in two shares of ABC stock, your expected gain is 2 x $10 = $20. Thus, there is a 50% chance that your gain will be $40, and otherwise your gain will be $20.
