Find the value of y. Express in simplest radical form.

Mathematics
1 answer:
Helga [31]2 years ago
8 0

Answer:

11

Step-by-step explanation:

If a^{2} +b^{2}=c^{2}

Then 5^{2} + 10^{2} = y^{2}

25 + 100 = y^{2}

125 = y^{2}

\sqrt{125} = \sqrt{y^{2}

11.18 = y

11.2 = y

11 = y

(I may be wrong because I am kind of new to this stuff)

Without solving, determine whether the solution of x = 21 is greater than or less than 21. Explain.
astraxan [27]

Without solving, the solution is greater than 21.  The can be proven because a fraction of x is equal to 21, therefore x cannot be less than 21.

What is the slope of the line y=5?
IceJOKER [234]

Answer:

0

Step-by-step explanation:

if you slightly change the equation to better fit standard form (without actually changing its meaning) you get

y = 0x + 5

which means the slope is 0

Also, a shortcut:

<h2><u>Horizontal lines always have a 0 slope while vertical lines have an undefined slope</u></h2>

A circle is graphed with its center on the origin.The area of the circle is 49 square units.What are the coordinates of the x-in
neonofarm [45]

Answer:

3.95 and -3.95

Step-by-step explanation:

To graph a circle you can use the formula or (x – h)^2 + (y – k)^2 = r^2. So substituting in the given, we get x^2+y^2=49/pi. The x intercept is when y=0. So x^2=49/pi and so

x = sqrt(49/pi) and rounding to the nearest tenth, we get 3.95 and -3.95 because it isn’t a principal square root.
