Answer:
Therefore the maximum height that the reach is 49 feet after 1.75 seconds.
Step-by-step explanation:
Given that,
A ball is thrown vertically upward. After t seconds its height is given by the function
where h is height in feet.
Maximum value:
Given function f(x)= at²+bt+c.
- Find the value
- Putting
in the given function.
- The maximum value of the given function is
.
Here a= -16 , b=56 and c=0
The ball attains its maximum height when s.
Putting the value of t in the given function
=49 feet
Therefore the maximum height that the reach is 49 feet after 1.75 seconds.
Answer:
Therefore the value of x is 5.
Step-by-step explanation:
Given:
△ABC ≅ △DEF,
EF = x 2 - 7, and
BC = 4x - 2.
To Find:
the values of x. = ?
Solution:
△ABC ≅ △DEF ........Given
If two Triangles are congruent then the Corresponding Parts of Congruent Triangles are Congruent.
∴ BC ≅ EF ...................CPCTC
Substituting the values we get
Now By Factorizing we get
Therefore the value of x is 5.
