Answer:
Can not prove that
Step-by-step explanation:
In case of p=1 and v=0, or p=0 => two equation alway true.

Answer:
not tangent
Step-by-step explanation:
AB will be tangent to circle O if AB ⊥ BO. That can be tested by checking to see if AB, BO, and AO satisfy the Pythagorean theorem.
According to the Pythagorean theorem, the length of the hypotenuse of a right triangle with legs 3.75 and 8 will be ...
hypotenuse = √(3.75² +8²) = √78.0625 ≈ 8.835
The length of AO is somewhat greater than that, so AB cannot be a tangent to the circle.

The angle ABO is obtuse.
Answer:
The slope between the two given point is -1
Step-by-step explanation:
The rule of the slope between two points (x1, y1) and (x2, y2) is
m =
Let us use this rule to solve the question
∵ The given points are (-2, 9) and (1, 6)
∴ x1 = -2 and y1 = 9
∴ x2 = 1 and y2 = 6
→ Substitute them in the rule of the slope above
∵ m =
→ Remember (-)(-) = (+)
∴ m =
∴ m =
→ Divide up by down
∴ m = -1
∴ The slope between the two given point is -1
Answer:
60.633 is the sum of 56.743 and 3.89
The correct answer for this question is "<span>|x-6| > 4."
</span>All real numbers more than 4 units from 6 (in an absolute value inequality).
We need to translate this sentence into a mathematical inequality.
"... units from 6 ..."
This means that the distance from 6 to a certain number.
x - 6
Since, we are talking about distance, place it inside an absolute symbol.
