Answer:
A.
Step-by-step explanation:
Circle with centre (0,2) will have the equation
(x)²+(y-2)² = r²
Finding r² by distance formula using P(-7,2)
r² = (-7-0)²+(2-2)²
r² = (-7)²
r² = 49
So substituting in the equation
x²+(y-2)² = 49
Answer:
63.7 inches
Step-by-step explanation:
half the base is 9 inches, so the equal legs are each
L = √(9² +21²) = 22.8473...
Perimeter = 2(22.8473) + 18 = 63.6946... ≈ 63.7 inches.
Answer:
a = 10/3
Step-by-step explanation:
This can be written as:
Anything to the power of 1/3 means to find the cube root. We can simplify this to:
I just multiplied 4 and 1/3 (because of the second index law 
). Now, we can add the powers because the bases are the same and we are multiplying (first index law):
a = 10/3
Hope this helps!
Answer:
If your asking for the Value of X the answer would be (-8)
Step-by-step explanation:
when your subtracting a negative, it's the same as addition, and if the equation should be equal to 2, then the answer would be (-8), because
(-8) - (-6) = -2.
