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)?

Answers

Answer 1

Answer:

The 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)

The graph in blue is the translation of the red to the left by 2 units.

So the equation is:

y = f(x + 2)Q4

y = h(x) is graphed

h(7) = 5h(h(7)) = h(5) = -1Q5

The 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 = 0

Find the area of a circle whose circumference is the same as the perimeter of a square of side 22 cm. (Take π = 22/7)

Answers

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

A map of a public park shows a circular pond. There is a bridge along a diameter of the pond that is 0.75 mi long. You walk across the bridge, while your friend walks halfway around the pond to meet you at the other side of the bridge. How much farther does your friend walk? Round your answer to the nearest hundredth. Use 3.14 for π.

Answers

C= πd, where C means circumference and d means diameter. 0.75 is the diameter of the pond, so 3.14 × 0.75 gives you 2.355mi.

You walked the diameter while your friend walked the HALF circumference. (2.355÷2) -0.75 is your answer

What is the Volume of the box 385 cubes?

Answers

Answer:You can calculate the volume of a box by multiplying length x width x height. Using the example of the single wall box this will be 102 x 102 x 102 which equals 1,061,208 cubic millimeters (㎣).

Step-by-step explanation:

The Volume of the box is 385/27 inch³.

What is Volume?

The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.

Many forms have various volumes. We have studied the several solids and forms that are specified in three dimensions, such as cubes, cuboids, cylinders, cones, etc., in 3D geometry. We will discover how to find the volume for each of these shapes.

Length = 11/3 inch

width - 5/3 inch

Height = 7/3 inch

So, the Volume of cuboidal box

= l w h

= 11/3 x 5/3 x 7/3

= 385/ 27 inch³

Also, Number of small cube = Volume of box/ Volume of small cube

385 = Volume of box / (1/27)

Volume of box = 385/ 27 inch³
