Answer: Choice B
Equation of a circle with (0,0) as its center and radius = 1
---------------------------------------------------------------
Explanation:
Recall that the unit circle is the equation
x^2 + y^2 = 1
This is a circle with center (h,k) = (0,0) and radius r = 1
It is in the form
(x-h)^2 + (y-k)^2 = r^2
We can write the first equation mentioned in the form sin^2(t)+cos^2(t) = 1
Using
x = cos(t)
y = sin(t)
t = angle
The point P(x,y) on the unit circle has an x coordinate of cos(t) and a y coordinate of sin(t). We can see this through drawing a right triangle.
Answer: 7^5 or 7 to the fifth power.
Step-by-step explanation: This is an exponent meaning you count the 7’s and in the first picture there’s 5 7’s. This means that the number your putting to a power is the yellow box so that’s 7 and the exponent is 5 not 4 because if you did 7 to the first power it’s still 7 so it would be 7 to the 5th power or 7^5

Answer: 34,788967
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given that in the weekly ad 5 pound bag of organic apples will cost 13.95 dollars
To find unit rate
Unit rate can be found in two ways either cost of 1 apple or no of apples for 1 dollars
I part:
5 apples = 13.95 dollars
1 apple = 13.95/5 (since direct variation)
Unit rate for one apple= 2.79 dollars
Part II:
13.95 dollars = 1 apple
1 dollar = 1/13.95 = 0.071
=0.07
But normally since apples are countable as 1,2 ... we use the first type of rate only unit rate per apple
