Step-by-step explanation:

Penny is falling under gravity

acceleration due to gravity is constant

Velocity is the integral of acceleration, which is linear

Displacement is the integral of velocity, which is quadratic

Answer: Quadratic

Explanation: Because the penny is falling, the penny will gain speed as it falls. This means that the penny will get rid of height in a shorter time making the line curved.

3. Find the area of the shaded region. Leave your answer in terms of pi. (1 point)
anygoal [31]

ANSWER

B.

(4 - \pi) {ft}^{2}

EXPLANATION

The area of the square is

{l}^{2}

The length of the square is

l = 2ft

The area of the square is

=  {2}^{2}  = 4 {ft}^{2}

Area of the circle is

= \pi \:  {r}^{2}

The radius of the circle is

r =  \frac{2}{2}  = 1ft

Area of circle is

= \pi \:  \times  {1}^{2}  = \pi {ft}^{2}

The area of the shaded region is

= (4 - \pi) {ft}^{2}

The triangular numbers are defined by the recursive formula t1 = 1, tn = tn - 1 + n, where n ∈N and n > 1. What are the first
GalinKa [24]

ANSWER

C) 1, 3, 6, 10, 15, 21, 28, 36, 45

EXPLANATION

The recursive formula is,

t_1=1,t_n=t_{n-1}+n

when n is a natural number greater than 1.

When n=2,

t_2=t_{2-1}+2

t_2=t_{1}+2 = 1 + 2 = 3

when n=3,

t_3=t_{2}+2 = 3 + 3= 6

when t=4,

t_4=t_{3}+2 = 6+ 4= 10

When t=5,

t_5=t_{4}+5 = 10 + 5 = 15

when t=6,.

t_6=t_{5}+6 = 15 + 6 = 21

when t=7

t_7=t_{6}+7 = 21 + 7 = 28

When t=8,

t_8=t_{7}+8 = 28 + 8 = 36

When t=9,

t_9=t_{8}+9 = 36 + 9 = 45

Hence the first nine triangular number are

C) 1, 3, 6, 10, 15, 21, 28, 36, 45

Answer:

The answer is 156.25π or about 490.625

Step-by-step explanation:

To find the area of a circle, you use the formula πr² (pi times radius times radius.) The radius is 12.5, so you plug it in to the equation. Once you plug the radius into the equation, you get π times 12.5 times 12.5. This simplifies to 156.25 times pi. If you want to use 3.14 as pi, the final answer is about 490.625. I hope this helps and that you have an fantastic day!!! Hope you stay safe!!!
