What are two numbers that multiply to get -64 , but when added get 0?

1 answer:

5 0

The simplest way in solving this is to find the factors of 64, and its corresponding negative values.

So, x = {1, 2, 4, 8, 16, 32, 64}
So its corresponding x values to get -64 are:
x = {-64, -32, -16, -8, -4, -2, -1}

Now, we notice that 8 and -8 are the same magnitude, with opposite signs. That means when they are added, they will cancel.

Hence, your two numbers are 8 and -8

Larry bought 24 marbles little lost half of his marbles how many did he lose

emmasim [6.3K]

Answer:

Step-by-step explanation:

his he had lost 12 of his marbles then he would only have 12 left to begin with.

to do this we can do the equation:

24/0.5 (the 0.5 is the represent that the 24 marbles had been split into two, a half for each party)

this would then give use our quotient of 12 marble he had lost

Consider a particle moving around a circle with a radius of 38cm. It rotates from 10 degrees to 100 degrees in 11 seconds. Calcu

kifflom [539]

Step-by-step explanation:

Given that,

Radius of circle, r = 38 cm = 0.38 m

It rotates form 10 degrees to 100 degrees in 11 seconds i.e.

$\theta_i=10^{\circ}=0.174\ rad$

$\theta_f=100^{\circ}=1.74\ rad$

Let $\omega$ is the angular velocity of the particle such that, $\omega=\dfrac{\omega_f-\omega_i}{t}$

$\omega=\dfrac{1.74-0.174}{11}$

$\omega=0.142\ rad/s$

We need to find the instantaneous velocity of the particle. The relation between the angular velocity and the linear velocity is given by :

$v=r\times \omega$

$v=0.38\times 0.142$

v = 0.053 m/s

So, the instantaneous velocity of the particle is 0.053 m/s. Hence, this is the required solution.
