Find the values of x and y

Mathematics
1 answer:
const2013 [10]3 years ago
7 0

Answer:

x = 79 y = 22

Step-by-step explanation:

x would be the same as the other side so 79 * 2 would be 158. A whole triangle is 180. 180 - 158 = 22

What is the square of √4​
Elan Coil [88]

Answer:

4

Step-by-step explanation:

To find the square of a number, you multiply it by itself. This means √4 * √4 gives the answer. √4 can be simplified to 2 because 2^2 is 4. So, 2 *2 gives the answer, which is 4.

I’ll give someone brainliest if they answer this
Dimas [21]

Answer:

2. The answer should be the last one.

3. The answer should be the first three.

Step-by-step explanation:

<u>Question 2</u>

KE = (1/2)mv²

2KE = mv²

v² = 2KE/m

v = ±√(2KE/m)

Therefore the answer should be the last one.

<u>Question 3</u>

b^(1/2) * b^(5/2)

Remember that the <u><em>product rule</em></u> states that b^x * b^y = b^(x+y)

So this means b^(1/2) * b^(5/2) = b^(1/2+5/2) = b^(6/2) = b^3

Also remember that the <u><em>power rule</em></u> states that √b = b^(1/2)

so this means b^(6/2) can also be written as (√b)^6

Therefore the answer should be the first three.

<em>If you want to double check all of your answers, just replace b with a number (for example, 2), and plug all of the choices into the calculator. Just </em><u><em>make sure</em></u><em> you are </em><u><em>very careful</em></u><em> when typing into the calculator.</em>
