Use rulers and compasses to draw a line which is perpendicular to line AB at point C
Answers
Answer:
Draw a line AB
Take a point C on AB
Fix the tip of compass at C and with a fix radius, cut AB on both sides of C
Mark those points D and E
Fix the tip of compass on D, and with the same radius, draw an arc above C
Do the same with E
Those two arcs will intersect at a point, mark the point F
Make a line passing through both C and F
Line CF is perpendicular to AB

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

Answer:
B) Domain: All real numbers; Range: y > 3
Step-by-step explanation:
I. x can be any value in real number
but if you look at the graph, the y is near 3 but not 3
So y is more than 3 and x is all real number
When x is domain and y is renge.
That makes domain is real number and renge is more than 3.

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
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.

(5 marks)
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) =

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
