Mathematics

Sauron [17]2 years ago
5 0

Answer:

3

Step-by-step explanation:

Again, anything to the 0th power is equal to 1.

The 0th power is attached to the b, so this means that b = 1. Multiply 9 and (1) together to get 9.

Now you can subtract 9 from 12 to get 3 as your final answer.

What set of reflections would carry hexagon ABCDEF onto itself?
Marianna [84]

When a set of reflections that carry a shape onto itself, it means that the final position of the shape will be the same as its original location

Reflections <em>(a) y=x, x-axis, y=x, y-axis </em>would carry the hexagon onto itself

First; we test the given options, until we get the true option

<u>(a) y=x, x-axis, y=x, y-axis</u>

The rule of reflection y =x is:

(x,y) \to (y,x)

The rule of reflection across the x-axis is:

(x,y) \to (x,-y)

So, we have:

(y,x) \to (y,-x)

The rule of reflection y =x is:

(x,y) \to (y,x)

So, we have:

(y,-x) \to (-x,y)

Lastly, the reflection across the y-axis is:

(x,y) \to (-x,y)

So, we have:

(-x,y) \to (x,y)

So, the overall transformation is:

(x,y) \to (x,y)

Notice that, the original and final coordinates are the same.

This means that:

Reflections <em>(a) y=x, x-axis, y=x, y-axis </em>would carry the hexagon onto itself

A boat travels 60 km upstream
trapecia [35]

Answer:

16 km/h   ….. still water boat rate

4 km/h   …. Current rate

Step-by-step explanation:

The speed of the boat supposed to be x km/h

The current rate is y km/h

(x + Y) * 3 = 60

(x – y) * 5 = 60

3x + 3y =60 ….. ①

5x – 5y = 60 ….. ②

① * 5 … 15x + 15y = 300   … ①’

② * 3 … 15x – 15y = 180   … ②’

①’- ②’ … 30y = 120

Y = 4 km/h   …. Current rate

15x = 300 – 15*4 = 240

X = 16 km/h   ….. still water boat rate
