[Been stuck on it for weeks, help me or I will fail. I will give Brainlist to anyone who has a well written descriptive answer p

lease.]
A bucket of paint has spilled on a tile floor. The paint flow can be expressed with the
function p(t) = 6t, where t represents time in minutes and p represents how far the paint is
spreading.
The flowing paint is creating a circular pattern on the tile. The area of the pattern can be
expressed as A(p) = лp².
Part A: Find the area of the circle of spilled paint as a function of time, or A[p(t)]. Show your
work. (6 points)
Part B: How large is the area of spilled paint after 8 minutes? You may use 3.14 to
approximate in this problem. (4 points)

Answer:

Part A: 28.26t²

Part B: 2,826 square unit

Explanation:

Part A:  

A[p(t)] = π (3t)² = 3.14 * 9t² = 28.26t²

Part B:

p(10) = 3(10) = 30

A(p) = 3.14 * 30² = 3.14 * 900 = 2,826 square unit

Answer:

Option d)

H_{0}: p = 0.75\\H_A: p \neq 0.75

Step-by-step explanation:

We are given the following in the question:

Three of four people believed that the state of the economy was the country's most significant concern.

They would like to test the new data against this prior belief.

The null hypothesis will state that the three of four people believed that the state of the economy was the country's most significant concern.

The alternate hypothesis will state that this is not true. It states that people believed that the state of the economy was the country's most significant concern is not the same.

p =\dfrac{3}{4} = 0.75

We design the null and the alternate hypothesis  

H_{0}: p = 0.75\\H_A: p \neq 0.75

fiasKO [112]
Using ur calculator you should get  15 degrees ( Use the sin-1  key.).

Angle complementary to x  is 90-15 = 75 degrees

and as  sin x = cos(90-x)  then cos 75 is also equal 0.2588
