Answer:

46.8 cm²

Step-by-step explanation:

The diagonal of the square has length \(\sqrt{6^2+10^2}=2\sqrt{34}\). Therefore, the radius of the circle is \(\sqrt{34}\), meaning the area is \(\pi(\sqrt{34})^2 \approx 34(3.14)=106.76\).

The area of the rectangle is \((6)(10)=60\) cm².

Subtracting the areas, the answer is 46.76 cm², which is 46.8 cm² to the nearest tenth.

Answer:

Step-by-step explanation:

y = -x²+4 and y = 2x+1

Therefore,  -x²+4 = 2x+1

x²+2x-3 = 0

x = 1,-3

There are two solutions:

(1,3) and (-3,-5)

The solutions to the system of equations are (x, y) = (-3, -5) and (1, 3).

We have,

To solve the system of equations:

Set the expressions for y equal to each other:

-x² + 4 = 2x + 1

Rearrange the equation to bring all terms to one side:

-x² - 2x + 3 = 0

Solve the quadratic equation by factoring, completing the square, or using the quadratic formula. In this case, we will use factoring.

Factor the quadratic equation:

(-x - 3)(x - 1) = 0

Set each factor equal to zero and solve for x:

-x - 3 = 0 or x - 1 = 0

Solve the first equation:

-x = 3

x = -3

Solve the second equation:

x = 1

Substitute the values of x back into one of the original equations to find the corresponding values of y.

For x = -3:

y = 2(-3) + 1

y = -6 + 1

y = -5

For x = 1:

y = 2(1) + 1

y = 2 + 1

y = 3

Therefore,

The solutions to the system of equations are (x, y) = (-3, -5) and (1, 3).

Hi!

If we multiply the top equation by (-2), then we can cancel out the y's.

-2(2x + 5y = 15)

-4x - 10y = -30

Now we add the second equation and our new equation together, and get:

x = 5

Now, we plug this in to one of the other equations

2(5) + 5y = 15

distribute

10 + 5y = 15

subtract 10 from both sides

5y = 5

divide both sides by 5

y = 1

Therefore, your answer is (5, 1)

Have a great day! :D

Answer:

(5, 1).

Step-by-step explanation:

2x+5y=15

5x+10y=35          

Multiply the first equation by -2:

-4x - 10y = -30

Add this 2 second equation:

x = 5.

Plug x = 5 into the first equation:

10 + 5y = 15

5y = 5

y = 1.

To calculate the interest for 1/2 a month over a period of 8 years, we first need to calculate the total number of months in 8 years:

Total number of months = 8 years x 12 months/year = 96 months

Next, we can calculate the interest for half a month:

Interest = Principal x Rate x Time

Where:

- Principal = $90,900.00

- Rate = 8.25% (annual interest rate)

- Time = 0.5/12 years (half a month, expressed in years)

Rate needs to be converted to a monthly rate, so we divide it by 12:

Rate = 8.25% / 12 = 0.6875% (monthly interest rate)

Time needs to be expressed in years, so we divide it by 12:

Time = 0.5/12 years

Now we can calculate the interest:

Interest = $90,900.00 x 0.006875 x 0.0416667

Interest = $25.08 (rounded to the nearest cent)

Therefore, the interest for 1/2 a month on a principal of $90,900.00 with an annual interest rate of 8.25% over a period of 8 years is $25.08.

Answer:

The interest for 1/2 month is $312.47, and the total interest for 8 years is $30, 032.64

Answer:

The average rate of change of the cost of a pack is 22 cents per year.

Another name for the average rate of change is slope.

Step-by-step explanation:

The average rate of change of the cost of a pack (\(r\)), in monetary units per year, is equal to the change in the average cost of a pack (\(\Delta c\)), in monetary units, divided by the change in time (\(\Delta t\)), in years. Then, the average rate of change is:

\(r = \frac{\$\,5.31-\$\,0.88}{2000-1980}\)

\(r = \$\,0.22\,\frac{1}{yr}\)

The average rate of change of the cost of a pack is 22 cents per year.

Answer

sqrt 419 and 5.215...

Step-by-step explanation:

Irrational numbers are numbers that cannot be expressed with a fraction. The square root of 419 and 5.215... never terminates + never repeats and therefore it is an irrational number.

Rounded to the nearest tenth, the acceleration in inches per second squared is approximately 15222.8 in/s².

To convert the acceleration from meters per second squared (m/s²) to inches per second squared (in/s²), we need to use the conversion factor between the two units.

1 meter is equal to 39.37 inches.

To convert the units, we can set up the following conversion factor:

1 m/s² = (39.37 in/m)^2 = 1550.0031 in/s²

Now, we can multiply the given acceleration in m/s² by the conversion factor to obtain the acceleration in in/s²:

Acceleration in in/s² = 9.81 m/s² * 1550.0031 in/s²

Acceleration in in/s² ≈ 15222.7568 in/s²

Rounded to the nearest tenth, the acceleration in inches per second squared is approximately 15222.8 in/s².

The required domain of the function If g(x) = f(-2x) is [-16, 8] in interval notation.

The domain of g(x) is the set of all x for which the function g(x) is defined. If g(x) = f(-2x), then the domain of g(x) is the same as the domain of -2x, subject to the restriction that f(x) is defined for the corresponding values of x.

In interval notation, the domain of -2x is (-∞, ∞).

However, since f(x) is defined only on the interval [-8, 4], the domain of g(x) must be restricted to values of x that correspond to values of -2x within the interval [-8, 4].

To find the corresponding values of x, we need to solve the equation -2x = t for x, where t is a number in the interval [-8, 4].

Solving for x, we get x = -t/2. So, the domain of g(x) is the set of all x such that -t/2 is in the interval [-8, 4], or equivalently, t is in the interval [-16, 8]. In interval notation, this is [-16, 8].

So, the domain of g(x) is [-16, 8] in interval notation.

Hope This Helps!!!

The rational function f(x) = (x² + 3x - 1) / (x + 1) has a vertical asymptote at x = -1, a horizontal asymptote at y = 0, and x-intercepts approximately at -3.3028 and 0.3028.

It approaches positive infinity for both positive and negative x values.

Graph is attached.

To graph the rational function f(x) = (x² + 3x - 1) / (x + 1), follow these steps,

In the attached graph.

Determine the vertical asymptote(s) by finding the values of x that make the denominator equal to zero.

Here, set x + 1 = 0 and solve for x:

x + 1 = 0

x = -1

So, there is a vertical asymptote at x = -1.

Determine the horizontal asymptote by comparing the degrees of the numerator and denominator.

If the degree of the numerator is less than the degree of the denominator, the horizontal asymptote is y = 0.

If the degrees are equal, the horizontal asymptote is the ratio of the leading coefficients.

here, the degree of the numerator (2) is less than the degree of the denominator (1), so the horizontal asymptote is y = 0.

Find the x-intercepts by setting the numerator equal to zero and solving for x:

x² + 3x - 1 = 0

Use the quadratic formula to find the x-intercepts, which are approximately -3.3028 and 0.3028.

Find the y-intercept by setting x = 0 in the function:

f(0) = (0² + 3 × 0 - 1) / (0 + 1) = -1

So, the y-intercept is (0, -1).

Determine the behavior of the function as x approaches positive and negative infinity.

As x becomes very large, the leading terms dominate the function's behavior.

Since both the numerator and denominator have a squared term, the function approaches positive infinity as x goes to either positive or negative infinity.

Now, plot the vertical asymptote, the horizontal asymptote, the x-intercepts, the y-intercept, and sketch the curve according to the behavior described above.

Therefore, the graph of the rational function f(x) = (x² + 3x - 1) / (x + 1) is attached.
