Pie

Answer:

Given,

Base(b)= 4.5 cm

Height(h)= 3 cm

Now,

Area of parallelogram= base * height

= 4.5 * 3

=13.5 cm^2

Hope this helps...

Good luck on your assignment...

Determine the center and radius: x2 + y2 - 10x + 8y -8 = 0

Kipish [7]

So our equation currently is ⇒ $x^2+y^2-10x+8y-8 = 0$

Let's first move all the constant to one side and group 'like variables' together:

$(x^2-10x)+(y^2+8y) = 8$

Now lets complete the square of both equations

$(x^2-10x+25)+(y^2+8y +16) = 8 + 25 + 16\\(x-5)^2+(y+4)^2 = 49\\(x-5)^2+(y+4)^2 = 7^2$

Now we know the circle's general equation format is:

⇒ $(x-h)^2+(y-k)^2 = r^2$

(h, k) ⇒ coordinate of the center of the circle
r ⇒ length of radius of circle

Thus the radius of the circle is 7

Hope that helps!

What is the value of the power a if 5 to the power of a is equal to 1/125

padilas [110]

First of all, you should know/notice that

$125=5^3$

You should also know how negative exponents work:

$a^{-m}=\dfrac{1}{a^m}$

So, if you wanted

$5^x=125$

the answer would be x=3, but since you want 125 to be at the denominator, the answer is x=-3:

$5^{-3}=\dfrac{1}{5^3}=\dfrac{1}{125}$
