A circle fits in a square with sides of 12 inches. What is the approximate area of the shaded region between the square and the circle? (Use 3.14 for and round to the nearest whole number.) 12 inches 12 inches​

Answers

Answer:

Step-by-step explanation:

Thus this area is 12^2 which is 144 sq. in. The area for the circle is dependent on the radius which would be half the diameter or length of the square. The formula for the area of a circle is πr^2 so 36π is the area of the circle

quadratic form to vertex form with a vertex of (-4,-1) and a y-intercept of 7

Answers

The quadratic function in vertex form is:

y = a(x - h)^2 + k

Where:

vertex = (h, k)
Axis of symmetry: x = h

The value of “a” determines whether the graph opens up or down, and makes the parent function wider or narrower.

The value of “h” determines how far left or right the parent function is translated.

The value of “k” determines how far up or down the parent function is translated.

Now that we have these definitions, we can substitute the given values into the vertex form to solve for “a”:

Use vertex = (-4, -1) and y-intercept, (0, 7):

7 = a(0+ 4)^2 - 1
7 = a(4)^2 - 1
7 = a(16) - 1

Add 1 to both sides:

7 + 1 = a(16) - 1 + 1
8 = 16a

Divide both sides by 16 to solve for “a”:

8/16 = 16a/16
1/2 = a

Since a = 1/2 (which is positive, implying that the parabola opens upward), and the vertex occurs at point (-4, -1) as the minimum point:

The quadratic equation in vertex form is:

y = 1/2(x + 4)^2 - 1

Line R passing through point P(-2, -1) and point (3,5). Find the slope of line R.

Answers

Answer:

Slope: 6/5

Step-by-step explanation:

For this problem, you'll need to apply the slope formula Y2-Y1

                                                                                             X2-X1.

Let's now assign each number their position in the formula. The first set of parentheses, (-2,-1) is going to translate to (x1,y1). (3,5) will translate to (x2,y2). Now, when you put it all together, you get 5-(-1) / 3-(-2). This would give you 6/5. That would be your slope. You can then proceed to graph it. Hope this helped! :))

Answers

Answer:

The identity is: cos(x+y)cos(x-y) = cos^2(x) - sin^2(y).  Answer to part (b) is 1/4

Step-by-step explanation:

cos(x+y) = cos(x) cos(y) - sin(x)sin(y)

cos(x-y) = cos(x)cos(y) + sin(x)sin(y)

For convenience, let A = cos(x) cos(y), and B = sin(x) sin(y).

Thus,

cos(x+y) = A - B

cos(x-y) = A + B, and

cos(x+y) cos(x-y) = (A-B)(A+B) = A^2 - B^2 = cos^2(x) cos^2(y) - sin^2(x)sin^2(y) = (1 - sin^2(x))(1 - sin^2(y)) - sin^2(x) sin^2(y) =

1 - sin^2(x) - sin^2(y) + sin^2(x) sin^2(y) - sin^2(x) sin^2(y) =

1 - sin^2(x) - sin^2(y) =

cos^2(x) - sin^2(y)

(b) Let x=45, and y=30, so we have that

cos(75)cos(15) = cos(45+30) cos(45-30) =

cos^2(45) - sin^2(30) =

(sqrt(2)/2)^2 - (1/2)^2 =

Is x = -2 a function?

Answers

Answer:

yes

Step-by-step explanation:

Answer:

No

Step-by-step explanation:

If you graph this function, you'll find that it looks like a vertical line, straight up and down. In a function, each x-value has to have exactly one y-value. In this function, however, any y-value you plug in gives you the same x-value: -2.

The one x-value, -2, has an infinite number of corresponding y-values, so this is definitely not a function.

1. Two planes departed from an airport at the same time. One flew east at the rate of 180 mph.
The other flew west at the rate of 330 mph. In how many hours will they be 1530 miles apart?

Answers

9514 1404 393

Answer:

  3 hours

Step-by-step explanation:

After 1 hour, the planes are separated by a distance of 180 +330 = 510 miles. At that rate, the time it takes for them to be 1530 miles apart is ...

  time = distance/speed

  time = (1530 mi)/(510 mi/h) = 3 h

After 3 hours, the planes will be 1530 miles apart.

The total of 3 suitcases is 127 lb. The gray suitcase weighs 11 lb more than the pink suitcase. The pink suitcase weighs 5 lb than the blue suitcase. How much does the blue suitcase weigh?

Answers

If the gray suitcase weighs 11 lb more than the pink suitcase, the pink suitcase weighs 5 lb than the blue suitcase, and the total of 3 suitcases is 127 lb, then the blue suitcase weighs 35.3 lb

Let the gray suitcase be represented by g

Let the pink suitcase be represented by p

Let the blue suitcase be represented by b

The gray suitcase weighs 11 lb more than the pink suitcase

g    =   p   +   11........(1)

The pink suitcase weighs 5 lb than the blue suitcase.

p   =  b  +  5

b  =  p  -  5...........(2)

Total of 3 suitcases = 127 lb

p  +  b  +  g    =  127............(3)

Substitute equations (1) and (2) into equation (3)

p  +  p  - 5 + p  +  11   =  127

3p  +  6   =  127

3p   =  127  -  6

3p   =  121

p  =  121/3

p  = 40.3 lb

Substitute p = 40.3 into equation (2)

b = p - 5

b  = 40.3  - 5

b  =  35.3

The blue suitcase weigh 35.3 lb
