What is the length of side BC if AC is 5 square root 2 m?

1 answer:

4 0

This is a right triangle, so AC is a hypotenuse. The other angles are each 45 degrees, so the legs AB and BC are equal length. a^2 + b^2 = c^2 a = b 2a^2 = (5sqrt2)^2 = 50 a^2 = 25 a = 5 Answer: 5

Answer:

$v=-1.46 \ m/s$

Step-by-step explanation:

So, as balloon reaches its maximum height i.e. 11 m , its velocity become 0.

Therefore, $v_{top}=0 \ m/s$ .

It is given that acceleration due to gravity should be taken as , $g=-9.8 \ m/s^2$ .(because it direction is down)

Now it is also given that upward direction is positive and downward direction is negative. So velocity should be negative.

Using equation of motion,

$v_{final}^2 - v_{initial}^2 =2\times a\times displacement$ .....eqn 1.

where , displacement = -11 m(because it displace towards down) and $a=g=-9.8\ m/s^2$

Putting these values in eqn 1 .

$v_{final}^2-0^2 =2\times 9.8 \times 11$

$v = \pm1.46 m/s.$

But as we know direction of velocity is downward.

Therefore, $v=-1.46 \ m/s$

where negative sign indicates its direction is downward.

What is the product of 3.6 x 4.2<br><br> How did you find it.

mixas84 [53]

Answer:

15.12

Step-by-step explanation:

3.6 x 4.2

first aline the decmials like you would regularly do to multiply.

Then multiply 2 x 6=12 and then 2 x 3=6 and put them down were you would already do noramly multiplying.

and then muliply 4x6=24 and 4x3=12 and do the same thing as you would do normaly and then add 72 and 144 to get 1512 and then count your decmail placing. which is 2 placeing in total which makes 1512 into 15.12

and now you done!

Example of how it should look...

3 . 6

× 4 . 2

+ 7 . 2

+ 1 4 4

= 1 5 1 2
