A bucket of paint has spilled on a tile floor. The paint flow can be expressed with the function r(t) = 3t, where t represents time in minutes and r 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(r) = πr2.
Part A: Find the area of the circle of spilled paint as a function of time, or A[r(t)]. Show your work.
Part B: How large is the area of spilled paint after 10 minutes? You may use 3.14 to approximate π in this problem.
What are the coordinates of the image of AABC after a dilation with center (0,0) and a scale factor of 3?
Answer:
factor of 3
Step-by-step explanation:
A population of bacteria grows according to the function p(t) = po · 1.42, where t is measured in hours. If
the initial population size was 1,000 cells, approximately hoy long will the it take the population to exceed 10,000
cells? Round your answer to the nearest tenth.
Answer:
The time duration for the population to exceed 10,000 is approximately 6.6 hours
Step-by-step explanation:
The given equation for the population of a bacteria is presented as follows;
[tex]p(t) = P_0 \cdot 1.42^t[/tex]
Where;
t = The time duration in hours
The initial population of the cells = 1,000
Therefore, at t = 0, P(0) = 1,000 = P₀ × 1.42^0
∴ P(0) = 1,000 = P₀ × 1 = P₀
P₀ = 1,000
When the population is 10,000, we have;
P(t) = 10,000 = 1,000 × 1.42^t
∴ 1.42^t = 10,000/1,000 = 10
㏒(1.42^t) = ㏒(10) = 1
∴ t × ㏒(1.42) = 1
t = 1/㏒(1.42) = 6.56649071898
∴ The time duration for the population to exceed 10,000, t ≈ 6.6 hours.

You must scuba dive to the entrance of your room at Jules' Undersea Lodge in Key Largo, Florida. The diver is 1 foot deeper than $\frac{2}{3}$ of the elevation of the entrance. What is the elevation of the entrance?
Answer:
the elevation of the entrance is -21
Step-by-step explanation:
The computation of the elevation of the entrance is shown below;
-15 = -1 + 2 ÷ 3e
e = -21
Hence, the elevation of the entrance is -21
We simply applied the above equation so that we can determine the elevation of the entrance

What is the mass in kg of a
solid metal cuboid with
dimensions 4cm, 5cm and
3cm and a density of
20g/cm3
Answer:
work out the area which is 4x5x3 this being 60 then divide this by 20 to get 3
The answer is 3kg
Answer:
[tex]density = mass \div volume \\ 20 = x \div 4 \times 3 \times 5 \\ 20 = x \div 60 \\ 20 \times 60 = x \\ x = 1200 \\ 1200 \div 1000 = 1.2kg[/tex]
What value of x satisfies the equation below?
[tex]\frac{-2x - 6}{5} = 4[/tex]
Answer: -13
Step-by-step explanation:
1. Isolate x: move 5 to the otherside
=> -2x-6=4*5 => -2x-6=20
2. Move 6 to the otherside: -2x=20+6 => -2x=26
3. Divide both sides by -2
=> x=26/-2 => x=-13

Solve please. Correctly
3(1 - 2a) = -3a - 18
Answer:
a = 7
Step-by-step explanation:
3(1 - 2a) = -3a - 18
3 - 6a = - 3a - 18
Add 18 to each side:
3 + 18 - 6a = - 3a - 18 + 18
21 - 6a = - 3a
Add 6a to each side:
21 - 6a + 6a = - 3a + 6a
21 = 3a
3a = 21
Divide each side by 3:
3a ÷ 3 = 21 ÷ 3
a = 7

Find the slope of the line that passes through the pair of points (6,-2) and (5,-4).
Show all work necessary and write your final answer in the box.
Answer:
slope = -10/7Step-by-step explanation:
co-ordinates = (6,-2) (5,-4)
slope = (y² - y¹) / (x² - x¹)
slope = (-4 - 6) / (5 - (-2))
slope = (-10) / (5+2)
slope = (-10) / 7
slope = -10 / 7
