Step-by-step explanation:
(a×b^-3×c^-3)⁵ / (a^-3×b⁴×c⁴)^-5
let's look at the numerator (the top) first :
a⁵×b^-15×c^-15
and now the denominator (the bottom) :
a¹⁵×b^-20×c^-20
both divided are (due to the commutative rules of multiplication we can split this first into the parts of the individual variables, and then multiply them all with each other) :
a⁵/a¹⁵ = 1/a¹⁰
b^-15 / b^-20 = b^(-15 ‐ -20) = b⁵
c^-15 / c^-20 = c⁵
so we get as result :
b⁵c⁵/a¹⁰
There is no picture added. I can not help with that then.
Answer:
32
Step-by-step explanation:
The problem above can be solved by using the <em>multiplication operation</em>.
Given: 400 people
8% of the people with green eyes
Let's solve:
Let x be<em><u> the number of people with green eyes.</u></em>
x = 400 x 8%
x = 400 x (0.08)
x = 32
So, the number of people surveyed with green eyes is 32. The rest of the surveyed people (368) have a different eye color.
Answer:
2
Step-by-step explanation:
Take the absolute value of the lowest y value.
So

Take the absolute value of highest y value.

Add those two together and divide by two.

So the amplitude is 2
Answer:
Radius, r = 61 cm
Step-by-step explanation:
According to the attached figure, we have,
Length of chord, AB = 22 cm
Such that, AP = PB = 11 cm
OP = 60 cm
It is required to find the radius of the circle. We know that radius of a circle is perpendicular to chord. So, APO forms a right angled triangle. Using Pythagoras theorem to find the radius of circle. Let it is r. So,

So, the radius of the circle is 61 cm.
