<h2>
Answer:</h2>
<u>The pressure will be 176 k Pa</u>
<h2>
Step-by-step explanation:</h2>
Boyle's law states that the product of volume and pressure gives us a constant value so we can write the expression as
P1V1 = P2V2
By arranging the equation we get
P1V1 / V2 = P2
Putting the values
(132 x 20 ) / 15 = P2
P2 = 176 k Pa
Answer: pool B has a greater circumference.
Step-by-step explanation:
The formula for determining the circumference if a circle is expressed as
Circumference = 2πr
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
Pool A has a radius of 48 feet.
1 foot ≈ 0.305 meters
48 feet = 48 × 0.305 = 14.64 meters
The circumference of pool A is
2 × 3.14 × 14.64 = 91.94 meters
Pool B has a diameter of 29.46 meters. Radius = diameter/2
Radius of pool B = 29.46/2 = 14.73 meters
The circumference of pool B is
2 × 3.14 × 14.73 = 92.5 meters
Therefore, pool B has a greater circumference.
Answer:
y = root under 24 (evaluate it if necessary)
or y = 2 root 6
Step-by-step explanation:
Let the reference angle be x
for the triangle in left,
b = 6-4 = 2
Now,
taking x as refrence angle,
cosx = b/h
or, cosx = 2/h
again,
for the bigger triangle,
taking x as reference angle,
cosx = b/h
or, cosx = b/6
As we can see base of bigger triangle is equal to hypotenuse of triangle at the left,
Let's suppose its a
so, cosx = a/6 = 2/a
now,
a/6 = 2/a
or, a² = 12
now,
for bigger triangle, using pythagoras theorem,
h² = p²+b²
or, 6² = y² + a²
or, 36 = y² + 12
or, y² = 24
so, y = root under 24

Step-by-step explanation:
The graph is a series of horizontal lines. A solid dot goes wherever there is an "or equal to" symbol in the inequality. An open dot goes where the point is not included in the function definition (but nearby points are).
