I think it's probably D. 0.0115 to 0.0125
Answer:
Centre = (-2,7) B
radius = 6
Step-by-step explanation:
The general formula for finding the equation of a circle is expressed as shown:
(x-h)²+(y-k)² = r² where (a,b) is the centre and r is the radius of the circle
Given the equation of the circle C in question (x+2)²+(y−7)²=36. We will compare the given equation to the general equation.
On comparison;
-h = 2
h = -2
-k = -7
k = 7
r² = 36
r = √36
r = ±6
From the answers gotten, it can be inferred that the centre of the circle (h,k) is (-2,7) and the radius of the circle is 6.
Radius of a circle cannot be a negative value so we will ignore the negative value of 6.
Answer:
sin(D) = cos(F)
cos(D) = sin(F)
tan(D) = 1/tan(F) which means tan(F) = 1/tan(D)
Step-by-step explanation:
First it is important to know that the sine of an angle is the fraction of the opposite side over the hypotenuse side, while cosine is the adjacent over the hypotenuse and finally tangent is opposite over adjacent. You can't take the sine, cosine or tangent of the right angle like this though.
sine is o/h
cosine is a/h
tangent is o/a
So let's do each angle.
Keep in mind E is the right angle so we can't take any trig function of it with SOH CAH TOA so let's do D first.
D has an adjacent side of f since e is the hypotenuse, which leaves d as the opposite so lets go throught he trig functions.
sin(D) = d/e
cos(D) = f/e
tan(D) = d/f
Now let's do the same with F. d is adjacent, e is the hypotenuse and f is opposite.
sin(F) = f/e
cos(F) = d/e
tam(F) = f/d
Now, you can actually match them up
sin(D) = cos(F)
cos(D) = sin(F)
tan(D) = 1/tan(F) which means tan(F) = 1/tan(D)
And just looking at that we've answered the question. let me know if that doesn't make

Answer:
Breaking up the multiplicand 8 into (5+3) allows us to apply the associative property of multiplication. See below.
Step-by-step explanation:
5*7 = 35. We want the product 8*7. Note that 8 = 5+3. Thus, 8*7=(5+3)(7) = 35 + 21, or 56.
