Answer: 64 ft
Step-by-step explanation:
We are given the following equation that models the baseball's parabolic path:
(1)
Where:
is the ball maximum height
is the time
is the initial height
With this information the equation is rewritten as:
(2)
Now, we have to find , and this will be posible with the following formula:
(3)
Where:
is the final velocity of the ball at the point where its height is the maximum
is the acceleration due gravity
Isolating :
(4)
(5)
(6)
Substituting (6) in (2):
(7)
Finally:
Answer:
(0,-8)
Step-by-step explanation:
90° rotation (x,y) > (-y,x)
180° rotation (x,y) > (-x,-y)
270° rotation (x,y) > (y,-x)
Given:
ABCD is a cyclic quadrilateral.
m∠C = 43°
To find:
The measure of ∠A.
Solution:
<em>In cylic quadrilateral, opposite angles are supplementary.</em>
⇒ m∠A + m∠C = 180°
⇒ m∠A + 43° = 180°
Subtract 43° from both sides.
⇒ m∠A + 43° - 43° = 180° - 43°
⇒ m∠A = 137°
The measure of ∠A is 137°.
C.all rhombuses are squares
Given:
Consider the given equation is
To find:
The solution of the equation for l.
Solution:
We have,
Substract 2W from both sides.
Divide both sides by 2.
Therefore, the correct option is 3.
