Answer: A
Step-by-step explanation:
7
pi is an irrational number and multiply it by 7 which is an rational number makes it irrational.
Answer:
(1, 4)
Step-by-step explanation:
It can work well to try the solutions to see which works:
- (1, 4) -- 4 > 1/2·1 +2 . . . true
- (-1, 1) -- 1 > 1/2(-1) +2 . . . false; 1 < 3/2
- (2, 3) -- 3 > 1/2·2 +2 . . . false; a number is not greater than itself
- (0, 2) -- 2 > 1/2·0 +2 . . . false; a number is not greater than itself
I believe the answer will be 0.035, hope this helped!
Answer: <em>S</em> ≈ 48.2°
Step-by-step explanation:
We can use trigonometry functions to solve.
Looking at angle <em>S</em>, t = 18 is the hypotenuse and r = 12 is the adjacent side. This means we can use the cosine function.
Answer:
B . Yes
Step-by-step explanation:
Recall: a tangent of a circle is perpendicular to the radius of a circle, forming a right angle at the point of tangency.
Therefore, if segment ST is tangent to circle P, it means that m<T = 90°, and ∆PST is a right triangle.
To know if ∆PST is a right triangle, the side lengths should satisfy the Pythagorean triple rule, which is:
c² = a² + b², where,
c = longest side (hypotenuse) = 37
a = 12
b = 35
Plug in the value
37² = 12² + 35²
1,369 = 1,369 (true)
Therefore we can conclude that ∆PST is a right triangle, this implies that m<T = 90°.
Thus, segment ST is a tangent to circle P.
