Answer:

40 ft

Step-by-step explanation:

The maximum height of the ball is the y- coordinate of the vertex

Given a parabola in standard form then the x- coordinate of the vertex is

$x_{vertex}$ = - $\frac{b}{2a}$

h(t) = - 16t² + 48t + 4 ← is in standard form

with a = - 16, b = 48 , thus

$x_{vertex}$ = - $\frac{48}{-32}$ = 1.5

Substitute t = 1.5 into h(t) for max. height

h(1.5) = - 16(1.5)² + 48(1.5) + 4

= - 36 + 72 + 4

= 40

a circle has an area of 225 square inches. if the radius of the circle is multiples by 6, then what is the new area of the circl

Lesechka [4]

Answer:

D: 8,100π in²

Step-by-step explanation:

The formula for area of a circle is

A = πr²

The radius is squared, so if the radius or a new circle is 6 times larger (multiplied by 6), the difference in area will be 36 times greater. So the area is

225π(36) = 8,100π

Answer:

The sequence of functions $\{x^{n}\}_{n\in \mathbb{N}}$ converges to the function

$f(x)=\begin{cases}0&0\leq x$ .

Step-by-step explanation:

The limit $\lim_{n\to \infty }c^{n}$ exists and converges to zero whenever $\lvert c \rvert$ . But, if $c=1$ the sequence $\{c^{n}\}$ is constant and all its terms are equal to $1$ , then converges to $1$ . Using this result, consider the sequence of functions $\{f_{n}\}$ defined on the interval $[0,1]$ by $f_{n}(x)=x^{n}$ . Then, for all $0\leq x$ we have that $\lim_{n\to \infty}x^{n}=0$ . Now, if $x=1$ , then $\lim_{n\to \infty }x^{n}=1$ . Therefore, the limit function of the sequence of functions is
