Which strategy can be used to multiply 6 x 198 mentally?

2 answers:

6 0

use estimation(i think). round 198 to 200 and multiply that by 6 in your head. 2*6=12 then add the two zeros for tens and ones place. 12+0+0= 1200

hope this helped!

What is the y-intercept of the function f(x) = -3x Ο Ο on who wire on Ο Ο

morpeh [17]

Answer:

see the explanation

Step-by-step explanation:

we know that

The y-intercept is the value of the function when the value of x is equal to zero. Also is called the initial value of the function

I will analyze two cases

Part 1) we have

$f(x)=-3x$

For x=0

substitute

$f(0)=-3(0)=0$

therefore

The y-intercept is the point (0,0)

Part 2) we have

$f(x)=-3^x$

For x=0

substitute

$f(0)=-3^0=-1$

therefore

The y-intercept is the point (0,-1)

Which expression is a perfect cube?

Alex17521 [72]

Answer:

Only $y^{24}$ is a perfect cube.

Step-by-step explanation:

$x^{8}$ is not a perfect cube because 8 is not a multiple of 3.

Now, $y^{24}$ is a perfect cube since 24 is a multiple of 3.

So, $y^{24}$ can be expressed as

$y^{24} =y^{8+8+8}= y^{8} \times y^{8} \times y^{8}= (y^{8}) ^{3}$

Again, $m^{28}$ is not a perfect cube as 28 is not a multiple of 3.

And also $s^{64}$ is not a perfect cube as 64 is not a multiple of 3.

Therefore, only $y^{24}$ is a perfect cube. (Answer)
