Find the angle measure C in the parallelogram ABCD.​

Answer:

178.98 square feet

Step-by-step explanation:

Alright so we need to find two areas here and find the difference to find the area of the path.

The two shapes involved is a smaller circle inside a bigger circle.

Let's look at the smaller circle, the gardening area.

You are given is has a radius of 8 ft.

The area of a circle is [tex]\pi \cdot r^2[/tex] where r is the radius.

So the area of the smaller circle is [tex]\pi \cdot 8^2[/tex].

Now time to look at the bigger area (which will have some overlapping area with the smaller one which will subtract out to find the area of path).

The diameter of the smaller circle was (8+8)=16 feet.

What is the diameter of the bigger one.  The path is 3 ft wide so we have to add a 3 before the diameter of the smaller circle to another 3 after that diameter to get the diameter of the bigger circle.  So the diameter of the bigger circle is (3+16+3)=22 feet.  The radius is half the diameter so the radius is 22/2=11.

The area of the bigger circle is [tex]\pi \cdot 11^2[/tex].

The area of the path=

the area of bigger circle     -      the area of smaller circle=

[tex]\pi \cdot 11^2-\pi \cdot 8^2[/tex]

Type this into your calculator with 3.14 instead of the [tex]\pi[/tex] button.

178.98 square feet

The answer is:

[tex]PathArea=178.98ft^{2}[/tex]

To calculate the are of the path alone, we need to add the width of the path to the radius of the garden in order to know is radius, then, calculate the total  area (using garden radius plus path width) and then, subtract it the area of the circular garden.

We know that the radius of the circular garden is equal to 8 feet, and the circular path has a width of 3 feet, so, the radius of the circular path will be:

[tex]CPath_{radius}=8feet+Path_{width}\\\\Path_{radius}=8feet+3feet=11[/tex]

Now, calculating the areas, we have:

Garden Area:

[tex]CircularGardenArea=\pi *radius^{2}\\\\CircularGardenRadius=\pi *8ft^{2}=3.14*64ft^{2}=200.96ft^{2}[/tex]

Total Area:

[tex]TotalArea=\pi *(8feet+3feet)^{2}=\pi *(11ft)^{2}=3.14*121ft^{2}=379.94ft^{2}[/tex]

Now, calculating the area of the path, we have:

[tex]TotalArea=CircularGardenArea+PathArea\\\\PathArea=TotalArea-CircularGardenArea\\\\PathArea=379.94ft^{2}-200.96ft^{2}=178.98ft^{2}[/tex]

Hence, we have that:

[tex]PathArea=178.98ft^{2}[/tex]

Have a nice day!

Final answer:

The truth value of the conditional statement ¬q → ¬p, with p being true and q being false, is false.

Explanation:

The question is asking about the truth value of the conditional statement ¬q → ¬p, where p is true and q is false. In a conditional statement of the form 'if q then p', written symbolically as q → p, the statement is false only when q is true and p is false. Otherwise, the statement is true. In this case, ¬q means 'not q' and ¬p means 'not p'. Given that q is false, ¬q is true. Given that p is true, ¬p is false. Thus, the statement ¬q → ¬p is of the form 'true → false', which makes the entire conditional statement false.

Final answer:

The truth value for the conditional statement ¬q → ¬p when p is true and q is false is false. This is because the contrapositive of any conditional statement must have the same truth value as the statement itself, and the given condition does not maintain this logical equivalence.

Explanation:

The truth value for the following conditional statement ¬q → ¬p when p is true and q is false is what we are trying to determine. The proposition ¬q → ¬p is the contrapositive of the conditional p → q. According to logic, a conditional proposition and its contrapositive always have the same truth value. Since we are given that p is true and q is false (¬q is true), using the definitions of the logical operators, we find that the contrapositive of the original conditional should also be true if the original is true.

In this case, the contrapositive is ¬q → ¬p, which, when translated in terms of the given truth values, becomes true → false. This suggests that if ¬q is true, then ¬p is true as well; however, since we know p is true, the situation given (¬q is true, ¬p is false) is not possible because it would not uphold the truth of the original proposition. Thus, the provided sequence of truth values does not maintain the logical equivalence of the contrapositive, making it incorrect. Therefore, the truth value of ¬q → ¬p is false under the given conditions.

The function C(F) represents the temperature of F degrees Fahrenheit converted to degrees Celsius.

The function C(F) represents the temperature of F degrees Fahrenheit converted to degrees Celsius. Temperature conversion is the process of converting between different temperature scales, such as Fahrenheit (°F), Celsius (°C), and Kelvin (K).

Each scale measures temperature differently, so conversions are necessary for various applications. The most common conversion formulas are: Celsius to Fahrenheit: °F = (°C × 9/5) + 32, and Celsius to Kelvin: K = °C + 273.15. These conversions are vital for international communication, weather reports, and scientific calculations.

Answer:

946

Step-by-step explanation:

To find just the remainder when dividing a polynomial by x-3, you could just plug in 3 into that polynomial.

If you were dividing by x+3, the remainder would just be the polynomial evaluated at x=-3.

Anyways plugging in 3 gives

7(3)^4 + 12(3)^3 + 6(3)^2 - 5(3) + 16

Just put this into your nearest calculator .

It should output 946.

You could use synthetic division or even long.

Synthetic Division.

We put 3 on outside because we are dividing by x-3.

3. | 7. 12. 6. -5. 16

| 21. 99. 315. 930

________________________

7. 33. 105. 310. 946

The remainder is the last number in the last column.

Hope this helps!

Final answer:

The value of 10!/(10-2)! simplifies to 90 after canceling out the common factorial terms, hence the correct answer is option C (90).

Explanation:

The expression 10!/(10-2)! represents a calculation involving factorials. The factorial of a number n is denoted n! and means the product of all positive integers from 1 up to n.

So, to simplify this expression, we can expand both factorials:

10! means 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1,
and (10-2)! or 8! means 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1.

When we divide 10! by 8!, the terms 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 (which is 8!) cancel out, leaving us with:

10 x 9 = 90.

Therefore, 10!/(10-2)! simplifies to 90, which is option C.

Answer:

y = - x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (4, - 3)

m = [tex]\frac{-3-2}{4+1}[/tex] = [tex]\frac{-5}{5}[/tex] = -1, hence

y = - x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 1, 2), then

2 = 1 + c ⇒ c = 2 - 1 = 1

y = - x + 1 ← equation in slope- intercept form

The equation is y = –x + 1.

To find the slope-intercept form of a line passing through two points, calculate the slope using the given points and then use one point to find the y-intercept. The final equation for the line through the points (–1, 2) and (4, –3) is y = –x + 1.

To write an equation in slope-intercept form for the line passing through the points (–1, 2) and (4, –3), we first need to calculate the slope (m) using the formula
m = (y2 - y1) / (x2 - x1). Plugging in our points gives us m = (–3 – 2) / (4 – (–1)) = –5 / 5 = –1. Now that we have the slope, we can use one of the points to find the y-intercept (b). Using the point (–1, 2) and the slope-intercept formula y = mx + b, we plug in the values to get 2 = (–1)×(–1) + b, simplifying to 2 = 1 + b, which yields b = 1. Thus, the equation is y = –x + 1.

[tex]f(x) = {2}^{x } \\ f(x) = 8 \\ \\ {2}^{x} = 8 \\ \\ {2}^{x } = {2}^{3} \\ \\ x = 3[/tex]

The value of x when f(x) = 8 is 3 in f(x) = 2^x

from the question, we have the following parameters that can be used in our computation:

f(x) = 2^x

To find the value of x when f(x) = 8, we need to solve the equation 2^x = 8.

We can rewrite 8 as 2^3

So, the equation becomes:

2^x = 2^3

Since the bases are the same, we can equate the exponents:

x = 3

Hence, the value of x when f(x) = 8 is 3.

Step-by-step explanation:

1 / tan(90 - x) = -√3/3                   Cross multiply

3 = -√3 * tan(90 - x)                     Divide by -√3

3/-√3 = tan(90 - x)                       Rationalize the denominator

3 * √3 /  (- √3 * √3  ) =tan(90-x)

3 * √3 / - 3 = tan(90 - x)               Divide

- √3           = tan(90 - x)               Take the inverse tan of -√3

tan-1(-√3) = 90 - x

-60 = 90 - x                                  Add x to both sides.

x - 60 = 90                                   Add 60 to both sides
