Answers
Answer:
273.25 feet2
Step-by-step explanation:
Daniela can only place the grass in the shaded areas and not the white areas so you want to start by finding the area of the full circle (12.5ft*25ft) and then subtracting the two equal quarter circles on the left and right corners, this can be done by using the radius given (5ft) and finding the area of what the full circle would have been 3.14*(5^2) which is equal too 78.5 (I got 3.14 from pi) and then dividing 78.5 by 4 to find the area of the quarter circle which is 19.625. since there are two quarter circles you multiply 19.625 by 2 and finally subtract your original recttangul by the two quarter circles 312.5(original rectangul)-39.25(the two quarter circles) giving you 273.25 feet2. hope that makes sense

Answers
Answer:
Step-by-step explanation:
Area of a parallelogram is given as the multiplication of its length by that of its height or breadth, however you call it.
In this question, you didn't state the length nor the breadth or height. You just listed the answers. It's very hard knowing the answer without having its dimensions. However, I can tell you that on the diagram or drawing you have there with you, multiply the two distance given to you together, it ought to give you one of the four options you listed above.

#natural logarithm #algebra 2
Answers
Condene the logarithms on the left side by applying the property, ln(a) - ln(b) = ln(a / b):
ln(x - 2) - ln(x - 3) = 1
→ ln((x - 2) / (x - 3)) = 1
Now take the exponential of both sides:
exp(ln((x - 2) / (x - 3))) = exp(1)
(x - 2) / (x - 3) = e
Solve for x :
x - 2 = e (x - 3)
x - 2 = e x - 3e
x - e x = 2 - 3e
(1 - e) x = 2 - 3e
x = (2 - 3e) / (1 - e) ≈ 3.582

A patio tile design is constructed from a square inscribed in a circle. The circle has radius 6 square 2 feet.
Answers
Answer:
Step-by-step explanation:
The edge of the square is 12 feet. Then the area of the square is 144 square feet.
What is the area of the square?All the sides of a square are congruent. Let a be the side length of the square. Then the area of the square is the square of the side length of the square.
Then the area of the square will be
Area of the square = a² square units
A porch tile configuration is developed from a square engraved all around. The circle has a span of 6√2 feet.
The edge of the square is calculated as,
(2r)² = a² + a²
2r² = a²
2 × (6√2)² = a²
2 × 36 × 2 = a²
a² = 144
a = 12 feet
Then the area of the square is calculated as,
A = (12)²
A = 144
The edge of the square is 12 feet. Then the area of the square is 144 square feet.
More about the area of the square link is given below.

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.
Answers
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.

The spinner below shows 10 equally sized slices. Charmaine spun the dial 40 times and got the following results.
Outcome Grey White Black
Number of Spins 25 9 6
Fill in the table below. Round your answers to the nearest thousandth.
(a) From Charmaine's results, compute the experimental probability of landing on white.
(b) Assuming that the spinner is fair, compute the theoretical probability of landing on white.
(c) Assuming that the spinner is fair, choose the statement below that is true:
1. The experimental and theoretical probabilities must always be equal.
2. As the number of spins increases, we expect the experimental and theoretical probabilities to become closer, though they might not be equal.
3. As the number of spins increases, we expect the experimental and theoretical probabilities to become farther apart.
Answers
I’m confused about (b) because the spinner has 10 sections but there has only been 3 outcomes. If the spinner has 3 sections the changes of white would be 0.333.
2. Is correct, the more times you spin the closer you’ll get to the theoretical probability.
Answer:
9/40= 0.225 (experimental probability for white)
(b) because the spinner has 10 sections but there has only been 3 outcomes. If the spinner has 3 sections the changes of white would be 0.333.
2. Is correct, the more times you spin the closer you’ll get to the theoretical probability.

After Dan makes a basket, Josephine claims she can find the amount of time the ball was in the air (from the time it leave's Dan's hand to the time it enters the basket),
Josephine says she can do this by using Dan's equation (1) = -1649 +18 + 8) and setting the equation equal to zero. Dan doesn't think Josephine's thinking is correct.
Who do you agree with?
Explain your reasoning using mathematical evidence.
Answers
Answer:
Step-by-step explanation:
The function is to blurry to see but you would not set the height function equal to zero. Instead h should be set to the height of the basket. The time elapsed would be the second time the ball was at the height of the basket. If I guess what the function is as
-16t^2+18t+8=10
-16t^2+18t-2=0
-16t^2+16t+2t-2=0
-16t(t-1)+2(t-1)=0
(-16t+2)(t-1)=0
So the ball is at 10ft at 0.125s and 1s. So it enters the hoop after 1 second. Of course this is dependent on if I guessed at the correct equation from the picture.
