Answer:
? = 7.2
Step-by-step explanation:
Remark
Is that a misshapen circle or is it an ellipse? I'm going to assume it is a circle, but if I am wrong, leave a comment. A tangent will meet a diameter's end at right angles which allows you to use the Pythagorean theorem.
Formula
a^2 + b^2 = c^2
Givens
c = 12
a = 9.6
b = ?
Solution
c^2 - a^2 = b^2
144 - 92.16 = b^2
b^2 = 51.84 Take the square root of both sides
sqrt(b^2) = sqrt(51.84)
b = 7.2
Answer:
A is a subset of B while B is the universal set.
Step-by-step explanation:
AB = A U B
A is a subset of B. That is A is contained in B.
Ans:C.
Remember equation Y=MX, and M is Slope.
now we know the line through the given point <span>(8,3)
</span>so put (8,5) into the equation
then equation Y=MX → (Y-3)=M(X-8)
and Slope M=5
so (Y-3)=5(X-8)
Answer:
14) y = 81
15) n = 6
Step-by-step explanation:
14)
54:30 = y:45
cross multiply: 45(54) = 30y, so y = 81
15)
6:3 = 12:n
cross multiply: 12(3) =6n, so n = 6
