64y^18 -1000z^6 = (4y^6)^3 -(10z^2)^3

Answer:

64y^{18} - 1000z^{6} = (4y^{6} )^3 - (10z^2)^3 =  (4y^6 - 10z^2) (16y^{12} + 40y^6z^2 +100z^4)

Step-by-step explanation:

The given expression is 64y^{18} -1000z^{6}

Here we can rewrite the given expression.

64 can be written as 4*4*4 = 4^{3}

y^{18} =( y^{6}) ^3 using the power of power rule of exponent.

So. 64y^{18} = (4y^6)^{3}

Now we can write 1000z^{6} = (10z^2)^3

Therefore, 64y^{18} - 1000z^{6} = (4y^{6} )^3 - (10z^2)^3

This can be written as using the formula (a - b)^3 = (a - b)(a^2 + ab + b^2)

Here a = 4y^6 and b = 10z^2

= (4y^6 - 10z^2) (16y^{12} + 40y^6z^2 +100z^4)

The triangle on the grid will be translated two units left. which shows the triangle translated 2 units left
Mariana [72]

Answer:

Take the coordinates of each vertex (corner point) and subtract 2 from the x-coordinate; leave the y-coordinate alone.

Step-by-step explanation:

Example: If one vertex is the point (5, 3), then it moves left 2 units to (3, 3).

If a vertex is at (-3, 1), then it moves 2 units left to (-5, 1).

100m In 9 3/5 seconds
Nostrana [21]

Answer:

Speed = 10.42 m/secs

Step-by-step explanation:

We have been given with:-

Distance = 100m

Time taken = 9\frac{3}{5} secs

1) First, we need to convert the mixed number 9\frac{3}{5} to an improper fraction.

<u>Method to convert a mixed number to an improper fraction</u>

<u>a\frac{b}{c} = \frac{c*a+b}{c}</u>

Applying the above formula, we get

9\frac{3}{5} = \frac{5*9+3}{5}

= \frac{45+3}{5}

= \frac{48}{5}

2) Now we need to convert \frac{48}{5} into a decimal by dividing 48 by 5.

We get time taken as 9.6 secs

3) We need to find the speed using the below formula:-

Speed = \frac{Distance}{Time taken}

Plugging the values of Distance and Time taken into the formula, we get

Speed = \frac{100}{9.6}

= 10.416 m/secs

4) Upon rounding it to the nearest hundredth, we get

Speed = 10.42 m/secs
