what is the remainder of 2x^3-12x^2+11x+2 divided by x-5

Answer:

34.2°

Step-by-step explanation:

sinB/b = sinA/a

sinB/7 = sin(40°)/8

sinB = 7sin(40°)/8

B=arcsin(7sin(40°))/8

So, to the nearest tenth, B is 34.2°.

We currently have two fractions: y / 1 and (y - 3) / 3.

In both cases, we are only concerned with the denominator. Yes, the numerator will change when we change the denominator, but that will not affect the answer to this question.

As such, we need to find the least common multiple of 1 and 3. That is 3. Therefore, the common denominator is 3.

Answer:

T [1;11].

Step-by-step explanation:

x-coordinate of the point T is:

x(T)=2*x(W)-x(S); ⇒ x(T)=2*(-3)+7=1;

y-coordinate of the point T is:

y(T)=2*y(W)-y(S); ⇒ y(T)=2*1+9=11.

Finally, T(1;11).

Answer:

[tex]dy \ = \ 0.1[/tex]

Step-by-step explanation:

Considering the Leibniz notation to represent the derivative of [tex]y[/tex] with respect to [tex]x[/tex], suppose [tex]y \ = \ f\left(x\right)[/tex] is a differentiable function, let [tex]dx[/tex] be the independent variable such that it can be designated with any nonzero real number, and define the dependent variable [tex]dy[/tex] as

                                                  [tex]dy \ = \ f'\left(x\right) \ dx[/tex],

where [tex]dy[/tex] is the function of both [tex]x[/tex] and [tex]dx[/tex]. Hence, the terms [tex]dy[/tex] and [tex]dx[/tex] are known as differentials

Dividing both sides of the equation by [tex]dy[/tex], yield the familiar expression

                                                         [tex]\displaystyle\frac{dy}{dx} \ = \ f'\left(x\right)[/tex].

Given that [tex]f\left(x\right) \ = \ x[/tex] and [tex]dx \ = \ 64.1 \ - \ 64 \ = \ 0.1[/tex], hence

                                                 [tex]f'\left(x\right) \ = \ 1[/tex].

Subsequently,

                                               [tex]dy \ = \ f'\left(64\right) \ \times \ 0.1 \\ \\ dy \ = \ 1 \ \times \ 0.1 \\ \\ dy \ = \ 0.1[/tex].

Answer: 112.5 square cm

Step-by-step explanation:

The area of the rectangle is [tex](20)(9)=180[/tex] square cm.

The area of the white triangle is [tex]\frac{1}{2}(9)(20-3-2)=67.5[/tex] square cm.

So, the area of the shaded region is [tex]180-67.5=112.5[/tex] square cm.

The length of the rectangle that makes the area to be 273 square feet is 21 feet.

An equation is an expression that shows the relationship between two or more variables and numbers.

Let x represent the length of the rectangle, hence:

Length * width = area

13 * x = 273

x = 21 feet

The length of the rectangle that makes the area to be 273 square feet is 21 feet.

Answer:

the mean and the median of the set of scores are the same.

Step-by-step explanation:

median = 89

mean = 96+77+86+97+89 = 445 / 5

= 89

mode = none

The mean and the median of the set of scores are the same.

Introduction to Mean, Median, and Mode: In statistics, we frequently choose a representative value to roughly characterise the entire collection of data. The name "measure of central tendency" denotes that this representative value is one around which the data is centred. The mean, median, and mode are these central tendencies. The most typical way to measure central tendency is with the mean. In actuality, it represents the mean of the specified set of data. Both continuous and discrete data can be used with it. In most cases, the median shows the midpoint of the given set of data when it is arranged in a specific order.

Mean: - Average value

Median: - Middle term (after arranging in either accending or descending order)

Mean = 445/5 = 89

Median = Middle term = 3rd term = 89

Mean and median are equal.

Hence, option D is correct

Step-by-step explanation:

So the general formula for compound interest is [tex]A = P(1+\frac{r}{n})^{nt}[/tex] where r is the interest rate, t is the time in years, and n is the amount of compounds per year. So plugging in the values for both equations you'll get

Opportunity Loans:

 [tex]A = 1600(1+\frac{0.0345}{12})^{(12)(1)}[/tex]

 [tex]A = 1600(1.002875)^{12}[/tex]

 [tex]A \approx 1600(1.035)[/tex]

 [tex]A = \$1,656.08[/tex]

  Now to find the interest accrued on this loan you simply subtract 1600 from the A or final amount

 [tex]Interest=1656.08-1600\\Interest=56.08[/tex]

General Loans:

 [tex]A = 1600(1+\frac{0.042}{4})^{(4)(1)}[/tex]

 [tex]A = 1600(1.0105)^4[/tex]

 [tex]A \approx 1600(1.042)[/tex]

 [tex]A = 1,668.27[/tex]

 To find the interest we do the same thing we did in the previous problem

Answer:

16, 100

Step-by-step explanation:

A perfect square is a number that can be achieved by multiplying a number by itself.

Example: 100 = 10 x 10, so it is a perfect square

2 is not a perfect square because it has no factors that can be multiplied with each other to equal 2. An easy way to check is to use the square root function on your calculator.

If the result is a whole number then it's a perfect square.

Answer:

Length = 120 ft

Total cost = 1500$

Step-by-step explanation:

First, to find the length of the backyard we reverse the formula (A = l * w) and divide 10,800 by 90.

10,800 ft^2 / 90 ft = 120 ft.

we can check this by plugging the length of 120 ft into the formula:

120 ft * 90 ft = 10,800 ft^2.

Next, to find the cost of the single length of fence we multiply our length (120 ft) by the cost ($12.50):

120 * 12.50 = $1500

Step-by-step explanation:

the travel paths of the plane build a right-angled triangle.

one travels north, which creates the vertical leg.

the other travels west, which creates the horizontal leg.

their distance is the Hypotenuse (the baseline opposite of the 90° angle), which we can get via Pythagoras

c² = a² + b²

c being the Hypotenuse, a and b being the legs.

how long are the legs ?

the plane going north travels at 240 km/h for 90 minutes.

the plane going west travels at 180 lm/h for 90 minutes.

90 minutes = 1.5 hours (1 hour 30 minutes).

so,

plane 1 went 240×1.5 = 360 km.

plane 2 went 180×1.5 = 270 km.

distance² = 360² + 270² = 129600 + 72900 = 202500

distance = sqrt(202500) = 450 km

2A

again Pythagoras :

130² = 80² + (2nd leg)²

16900 = 6400 + (2nd leg)²

10500 = (2nd leg)²

2nd leg = 102.4695077... m

so, the full perimeter is

130 + 80 + 102.4695077... = 312.4695077... m

312.4695077... = 100%

1% = 100%/100 = 3.124695077... m

how many % are 220 m ? well as many as how often 1% fits into 220 m :

220 / 3.124695077... = 70.40686998... %

3A

again Pythagoras :

the legs of that inner right-angled triangle are (as you correctly wrote) 40 m and 45 m.

the fence is the Hypotenuse, and we get

fence² = 40² + 45² = 1600 + 2025 = 3625

fence = 60.20797289... m ≈ 60 m

please burn that into your brain forever for any right-angled triangle situations :

The set when z = -5 is {-27, -9, -5}

The set is given as:

{(4z-7,z-4,z) |z is any real number}

When z=-5, we have:

4z - 7 = 4(-5) - 7 = -27

z - 4 = -5 - 4 = -9

z = -5

So, we have:

{(4z-7,z-4,z) |z is any real number} ⇒ {-27, -9, -5}

Hence, the set when z = -5 is {-27, -9, -5}

Each one of those has 5 sticks for the ties, which in turn each have 6 leaves to represent the jackets and therefore a complete outfit. The solution is found by getting the total number of leaves on the tree.
