Answer:
D
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
here (h, k) = (- 6, - 8), thus
(x + 6)² + (y + 8)² = r²
The radius is the distance from the centre to a point on the circle
Calculate r using the distance formula
r = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 6, - 8) and (x₂, y₂ ) = (0, 0)
r = 
= 
= 
= 10
Hence
(x + 6)² + (y + 8)² = 100 → D
Answer:
- <u><em>Option A. F T → F</em></u>
Explanation:
A conditional is represented by:
Where p is called the antecedent, and q is the consequent.
Thus, a conditional states that if the antecedent is true, its consequent is also true; also, if the consequent is false, then the antecedent must be false.
On the other hand, if the antecedent is true, the consequent can be either true or false.
<u>1. State the antecedent of the conditional and is truth value</u>
- Truth value: False, because 6 is not greater than 10.
<u>2. State the consequent of the conditional and its truh value</u>
- Truth value: True, because 8 times 3 is 24.
<u>3. Truth value of the conditional</u>
Hence, the truth value of the conditional is:
Which is the option A.
The decimal number is 0.9
Answer:
5q+9
Step-by-step explanation:
6q minus a is 5 q so then it would equal 5q+9
which is 4+5 equals 9
