Answer:
Perimeter of a square=circumference of circle
4×22=2πr
44=πr
r=14
Area of circle=πr2
22/7×14×14
28×22
616
Answer:
176cm²
Step-by-step explanation:
Side of square = 22cm
Perimeter of square = 88cm
Circumference of circle = perimeter of square
2π r = 88cm
2 x 22/7 x r = 88cm
44/7 x r = 88cm
r = 88 x 7/44
r = 14cm
Area of circle = π x r x r
= 22/7 x 14 x 14
= 44 x 4
= 176 cm²
The lines 2x - y = 8 and 4x - 2y = 16 intersect at _______.
The solution is Option C.
The system of equations are same and they have infinite number of points
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the first equation be P
2x - y = 8 be equation (1)
Let the second equation be Q
4x - 2y = 16 be equation (2)
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ ) = 2
Substituting the values in the equation , we get
Divide equation (2) by 2 , we get
2x - y = 8 be equation (1)
Therefore , the value of equation (1) = equation (2)
Hence , there are infinite number of solutions to the equations

Answer:
1 21/50
Step-by-step explanation:
3 3/4 = (3/4 x 4/4) = 3 9/12
2 1/3 = (1/3 x 3/3) = 2 4/12
3 9/12 - 2 4/12 = 1 21/50

1. The graph of y = f(x) is a parabola whose vertex is at (1, -2). The graph of y = f(x - 3) is also a parabola. Where is the vertex of the graph of y = f(x-3)? Write your answer as an ordered pair.
2. The graph of has the line as an axis of symmetry. The graph also passes through the point. Find another point that must lie on the graph of y = f(x).
3. The graph of y = f(x) is shown in the first picture in red. Find the equation that corresponds to the blue graph.
Enter your answer in the form "y = …".
4. The graph of y = h(x) is shown in red in the second picture. Compute h(h(7)).
(Assume grid lines are spaced 1 unit apart.)
5. In the third picture is a portion of the graph of a function, y=u(x):
What is the exact value of u(-2.72)+u(-0.81)+u(0.81)+u(2.72)?
Answer:
Q1The graph of y = f(x), has vertex at (1, -2)
The vertex of a function f(x - 3) is going to be:
(1 - 3, -2) = (-2, -2)Q2The graph of y = f(x) has the line x = 5 as an axis of symmetry. The graph also passes through the point (8,-7). Find another point that must lie on the graph of y = f(x).The axis of symmetry is at the same distance from the symmetric points.
x = 5 is a vertical line. The point (8, -7) is 3 units to the right. So the mirror point will be 3 units to the left and have same y-coordinate: x = 5 - 3 = 2
The point is (2, -7)
Q3The graph in blue is the translation of the red to the left by 2 units.
So the equation is:
y = f(x + 2)Q4y = h(x) is graphed
h(7) = 5h(h(7)) = h(5) = -1Q5The graph of the function y = u(x) given
This is a odd function.
The coordinates of u(x) and u(-x) add to zero because u(-x) = -u(x)
Therefore:
u(-2.72) + u(-0.81) + u(0.81) + u(2.72) = [u(-2.72) + u(2.72)] + [u(-0.81) + u(0.81)] = 0 + 0 = 0Which of these expressions is equivalent to 1/4x − 16 ?

Simplify the fraction below.
35/4
Answer:
8 3/4
Step-by-step explanation:
find the greatest common factor of 35 and 4, which is 1. Then divide both 35 and 4 by the greatest common factor to get the following simplified fraction: 35/4
If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. You could convert it into a whole number or mixed number fraction. Which would now be 8 3/4
