Answer:
Right option is c 16 cm
Step-by-step explanation:
From the question,
The radius of the circle, the point drawn from the center of the circle to piont X and the length of the tangent drawn from point X to the point of tangency all form a right angle triangle.
Using pythagoras theorem,
a² = b²+c²...................... Equation 1
Where b = the length of the tagent, a = length of the point drawn outside the circle from the center, b = radius of the circle.
Given: a = 34 cm, b = 30 cm.
Substitute into equation 1
34² = 30²+c²
c² = 34²-30²
c² = 1156-900
c² = √256
c² = 16 cm.
Hence the right option is c 16 cm
Answer:
The time can not be negative. Thus, the domain of the given graph function must have the interval [0, ∞].
In other words, t ≥ 0.
Step-by-step explanation:
We know that the domain of a function is the set of input or argument values for which the function is real and is defined.
Given that the graph is showing the height of a thrown ball x seconds after it is thrown.
We must check that the time can not be negative. Thus, the domain of the given graph function must have the interval [0, ∞].
In other words, t ≥ 0.
Answer:
x = 3, x = 4
Step-by-step explanation:
To find the zeros of the function, equate f(x) to zero, that is
(x - 3)(2x - 8) = 0
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3 ← smaller solution
2x - 8 = 0 ⇒ 2x = 8 ⇒ x = 4 ← larger solution
Divide each side by ( I R ) .
