Identify the vertex, the axis of symmetry, the maximum or minimum value, and the domain and range of the function for f(x)=(x-9)

Rzqust [24]

Identify the vertex, the axis of symmetry, the maximum or minimum value, and the domain and range of the function for f(x)=(x-9)^2-29

we have

f(x)=(x-9)^2-29

This is a vertical parabola, open upward

The vertex represent a minimum

The vertex of the parabola is the point (9,-29)

The domain is all real numbers

The range is the interval {-29, infinite)

$y\ge-29$

The axis of symmetry of a vertical parabola is equal to the x-coordinate of the vertex

In this problem

axis of symmetry is x=9

What is the answer I will give brainlyest

Scorpion4ik [409]

Answer:

31.5 squared cm

Step-by-step explanation:

Let's start with the triangle part :)

We have a base half a base of 3, so let's add 3 more to make it complete, which gives us 6.

6cm (base) x 6 cm (height) = 36 cm.

Since it's a triangle, we must divide by 2 which gives us 18 cm.

Now let's move on to the circle.

we have a radius of 3.

in order to find area of a circle, we have to do pi x r squared.

We have a radius of 3 so let's square it, which give us 9. after that we multiply 9 by pi.

In the directions, it says use 3 for pi. So we do

3 x 9 which equals 27.

But WAIT- it's a half circle so we divide 27 by 2 which gives us 13.5 cm.

Let's add the two

18 cm + 13.5 cm = 31.5 cm squared (remember to square it since it's area!!)

I hope this helped!!! <3

Each tile is 3/2 feet by 3/2 feet. There are 10 tiles on the bathroom floor.

Yuki888 [10]

9514 1404 393

Answer:

22.5 square feet

Step-by-step explanation:

The area covered by one tile is the product of its dimensions:

A = lw

A = (3/2 ft)(3/2 ft) = 9/4 ft²

The area covered by 10 tiles is 10 times the area covered by one tile. The area covered is ...

covered by tiles = 10 × 9/4 ft² = 90/4 ft²

covered by tiles = 22.5 ft²

22 1/2 square feet is the area covered by tiles.

What is the simplified form of the expression 2 radical 18 - 5 radical 32

Alex Ar [27]

Answer:

-14√2

Step-by-step explanation:

Note that 18 = 2*9, and that 9 is a perfect square. Therefore,

2*√18 = 2*3*√2, or 6√2.

Next, note that 32 = 2*16, and that 16 is a perfect square. Therefore,

-5*√32 = -5*√2*√16, or -5*√2*4, or -20√2.

Combining these two results, we get:

6*√2 - 20√2, or -14√2
