There are 4 triangles and 8 squares. What is the simplest ratio of triangles to squares?

Answer:

(−12,2)

Step-by-step explanation:

1:

Dividing the function by 2 divides all the y-values by 2 as well. So to get the new point, we will take the y-value

(4) and divide it by 2 to get 2

.

Therefore, the new point is

(−12,2)

2:

Subtracting 2 from the input of the function makes all of the x-values increase by 2 (in order to compensate for the subtraction). We will need to add 2 to the x-value

(−12) to get −10

.

Therefore, the new point is

(-10,4)

3:

Making the input of the function negative will multiply every x-value by

−

1

. To get the new point, we will take the x-value

(−12) and multiply it by −1 to get 12.

Therefore, the new point is

(12,4)

4:

Multiplying the input of the function by 4 makes all of the x-values be divided by 4 (in order to compensate for the multiplication). We will need to divide the x-value

(−12) by 4 to get −3

.

Therefore, the new point is

(−3,4)

5:

Multiplying the whole function by

4

increases all y-values by a factor of

4

, so the new y-value will be

4

times the original value

(4), or 16.

Therefore, the new point is

(−12,16)

6:

Multiplying the whole function by

−1

also multiplies every y-value by

−1

, so the new y-value will be

−1

times the original value

(4), or −4.

Therefore, the new point is

(−12,−4)

By using trigonometric formulas and integration rules, we conclude that the integral is approximately equal to - 7.764 units.

In this problem we must determine the solution to a definite integral of trigonometric equations, which requires the use of trigonometric formula and integration rules to be found. The integral can be simplified by using the following formulas:

sin⁴ x = (1 / 8) · (3 - 4 · cos 2x + cos 4x)

sin² x = (1 /2) · (1 - cos 2x)

Then, the integral is simplified into this form:

[tex]I = \pi \int \limits_{\frac {\pi}{6}}^{\frac{3\pi}{4}} \sin^{4} x \,dx + 4\pi \int \limits_{\frac {\pi}{6}}^{\frac{3\pi}{4}} \sin^{2} x \,dx[/tex]

[tex]I = \frac{\pi}{8} \int \limits_{\frac {\pi}{6}}^{\frac{3\pi}{4}} (3 - 4\cdot \cos 2x + \cos 4x) \,dx + 4\pi \int \limits_{\frac {\pi}{6}}^{\frac{3\pi}{4}} (1 - \cos 2x) \,dx[/tex]

[tex]I = \frac{3\pi}{8}\cdot x - \frac{\pi}{4} \cdot \sin 2x + \frac {\pi}{32}\cdot \sin 4x - 4\pi \cdot x - 2\pi\cdot \sin 2x[/tex], for x ∈ [π / 6, 3π / 4]

And the definite integral is:

I = 2.159 + 1.466 - 0.085 - 23.028 + 11.724

I = - 7.764

The definite integral of f(x) = sin⁴ x + 4 · sin² x for x ∈ [π / 6, 3π / 4] is approximately equal to - 7.764.

The percent markup is 124.30%.

The wholesale cost of one candle is $5.35

The selling price of the candle is $12

The profit she earns = 12 - 5.35

                                  = $6.65

Here we have to find the percent markup.

The formula for the percent markup =( profit/ wholesale cost )× 100

Markup percent = 6.65 / 5.35 × 100

                          = 1.24299 × 100

                          = 124. 30%

Therefore the markup percentage is 124.30%.

1. The scenario represents a payout annuity.

2. Marcy can withdraw $1,833.60 per quarter until after 3 years when the inheritance will be exhausted.

A periodic withdrawal is the opposite of a periodic payment.

In a periodic withdrawal, the investor withdraws a constant amount from the investment that earns interest until it is exhausted.

A periodic withdrawal is the same as a payout annuity, which involves periodic receipts from the invested capital.

Using an online finance calculator, we can compute the quarterly withdrawals as follows:

N (# of periods) = 12 quarters (3 x 4)

I/Y (Interest per year) = 6%

PV (Present Value) = $20,000

FV (Future Value) = $0

Results:

Withdrawals = $-1,833.60

Sum of all periodic payments = $-22,003.20

Total Interest $2,003.20

Thus, in this payout annuity, Marcy can withdraw $1,833.60 quarterly for 3 years.

I hope it will be helpful for you.

As per the given condition for the system of equation, the two numbers are equal to 4 and 3.

As given in the question,

To begin with the solution, let the two unknown numbers be x and y. Now, translating the two mathematical statements into system of equations,

When three times the first of two numbers decreased by the second number equals 9.

3 x - y = 9 ____(1)

Twice the first number increased by the second number equals 11,

2 x + y = 11   ____(2)

By solving resultant system of equations we get,

3 x - y = 9

2 x + y = 11

5x        = 20                    (by adding the two equations)

=> x = 4

Substituting the value of x in second equation,

y = 11 - 2x

Answer:

if x=0than 3×0×(6×0)_< 9

Answer:

40

Step-by-step explanation:

Answer:  [tex]-4 < m \le -3[/tex]

=========================================================

Reason:

If m = -4, then f(x) = m becomes f(x) = -4. This yields the single solution x = -4

How do we get this solution? Start at -4 on the y axis. Move horizontally until reaching the curve. You should arrive at (-4,-4) which is the lowest point of this curve. Then move upward until reaching the x axis to arrive at x = -4

All of this says that the input x = -4 leads to the output y = f(x) = -4

---------------

We've gone over m = -4 leading to one solution, so that's out of the question since we want two solutions.

But if m = -3 for instance, then notice how tracing a horizontal line to the curve arrives at two locations instead of one. We arrive at x = -2 and x = -5 as the solutions to f(x) = -3

All of these solutions mentioned are negative which fits the criteria we're after. If m is in the interval from -4 to -3, excluding -4 but including -3, then we'll have f(x) = m with two negative solutions for x.
