Answer:
my acc just got yeeted by a penguin pfp
Step-by-step explanation:
So hmm check the picture below
a)
well, clearly is 80 ft/s
b)
when t = 1? well 80(1)
c)
in the picture, x-axis is the time and y-axis is the height
so, it reaches its maximum at the vertex, after "x" seconds
so it reached the vertex after
d)
the maximum height of the ball is
Definition
An irrational number is a number that cannot be expressed in as a fraction. It has decimal expression that does not terminate.
An example will be √2.
Reason:
(1) √2 cannot be expressed as a fraction form
(2) √2 has decimals that does not terminate
The equation of function g(x) = 2(x -7)² - 1, and the values of h and k are 7 and -1, respectively.
<h3>What is a quadratic equation?</h3>
A quadratic equation is the second-order degree algebraic expression in a variable.
The standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
The function is given as:
f(x) = 2x² - 1
When the function is translated with 7 units left, the transformation rule is:
(x,y) -> (x + 7, y)
So,
g(x) = 2(x -7)² - 1
A quadratic function is expressed as:
g(x) = a(x -h)² + k
By comparison, the values of h and k are 7 and -1, respectively.
