Answer:
88m
Step-by-step explanation:
Hey There!
Essentially the question is asking for the circumference of the circular garden
The first thing that we want to do is find the formula of for the circumference
[tex]C=2r\pi[/tex]
14x2=28
they said to use [tex]\frac{22}{7}[/tex] for pie
so we do
[tex]\frac{22}{7} x28=88[/tex]
so the circumference is 88m
or the amount of fencing needed is 88m

Let y=f(x) be the particular solution to the differential equation dy/dx=2x−1/y^2 with the initial condition y(0)=3. Which of the following is an expression for f(x)?
A. √(x^2−x+9)
B. −3/3x^2−3x−1
C. (3x^2−3x)^1/3+3
D. (3x^2−3x+27)^1/3
Answer:
D. (3x^2-3x+27)^1/3
Step-by-step explanation:
dy/dx=2x−1/y^2
Cross multiply to get Y's and X's on different sides.
(y^2)dy = (2x-1)dx
Take the integral of each side
∫(y^2)dy = ∫(2x-1)dx
y^3/3 = 2x^2/2 - x + C
Multiply both sides by 3
y^3 = 3x^2 - 3x + C
Plug in (0,3) and solve for C
27 = 0 - 0 + C
C = 27
Plug in C to the equation
y^3 = 3x^2-3x+27
Cube root both sides to get just y
y = √(3x^2-3x+27)
y = (3x^2-3x+27)^1/3
D.
The particular solution of the equation will be "[tex](3x^2-3x+27)^\frac{1}{3}[/tex]".
Differential equationAccording to the question,
→ [tex]\frac{dy}{dx}[/tex] = [tex]\frac{2x-1}{y^2}[/tex]
By applying cross-multiplication,
(y²)dy = (2x - 1)dx
By integrating both sides, we get
→ ∫(y²) dy = ∫(2x - 1) dx
[tex]\frac{y^3}{3}[/tex] = [tex]\frac{2x^2}{2}[/tex] - x + C
By multiplying "3" both sides, we get
y³ = 3x² - 3x + c
By substituting "(0,3)" in above equation,
27 = 0 - 0 + C
C = 27
By substituting value of C in the above equation,
y³ = 3x² - 3x + 27
By cubing both sides,
y = √(3x²-3x+27)
= [tex](3x^2-3x+27)^\frac{1}{3}[/tex]
Thus the above answer i.e., "Option D" is correct.

Last year, Frank earned $7.48 per hour. This year the company decided to give him a 30% increase in his hourly rate. How much is Frank earning per hour this year? A. $7.78 O B. $9.72 O c. $10.48 D. $22.44 E $24.93
Answer:
B 9.72
Step-by-step explanation:
If we imagine 7.48 is 100% Then we can use multiply and divide to find 30%. It goes like this. x/7.48 = 30/100. Where x is the unknown. Take 30 times 7.48 which is 224.4 then divide by 100 we get 2.24 dollars. Added to 7.48 we get 9.72

Answer:
B
Step-by-step explanation:
There isn't really much explaining I can do but each time you find the co-ordinate of a point you can cancel out a possibility.
For example, one of the points is (-3,4) and the only one without this point is C so that answer is cancelled out, and you keep going this way until you are left with only on possible answer and that should be B.
Top left = (-3,4)
Bottom left = (-2, -4)
Top right = (3,4)
Bottom right = (1,-4)
Given the formula l = prt, where l = interest earned, P is the principal invested and r is the interest rate. If $245 is the principle invested at an interest rate of 3%, and Paul earned 69.80 interest, how long, t, (in years) was the money invested for?
Answer:
t= 9.49 years which can be estimated to 9 years
Step-by-step explanation:
Given the formula l = prt,
Where P is the principal=$245
r is the interest rate.=3%,
l = interest earned=$69.80
l = prt
Therefore time, t= I/ pr
t= 69.80/ 245 x 3%
t=69.80/ 245 x 0.03
t= 9.49 years which can be estimated to 9 years

Pranav and Jaidee are selling flower bulbs for a school fundraiser. Customers can buy bags of
windflower bulbs and bags of daffodil bulbs. Pranav sold 9 bags of windflower bulbs and 9 bags
of daffodil bulbs for a total of $198. Jaidee sold 2 bags of windflower bulbs and 5 bags of
daffodil bulbs for a total of $86. Find the cost each of one bag of windflower bulbs and one bag
of daffodil bulbs.
Answer:
wildflower: $8
daffodil: $14
Step-by-step explanation:
9w + 9d = 198
2w + 5d = 86
-18w - 18d = -396
(+) 18w + 45d = 774
----------------------------------
27d = 378
d = 14
9w + 9(14) = 198
9w = 72
w = 8
wildflower: $8
daffodil: $14

2. By definition, jumbo shrimp are those that require between 10 and 15 shrimp to make a pound. Suppose that the number of jumbo shrimp in a 1-pound bag averages μ = 12.5 with a standard deviation of σ = 1.5, and forms a normal distribution. What is the probability of randomly picking a sample of n =25, 1-pound bags that average more than M = 13 shrimp per bag?
Answer:
0.0475 = 4.75% probability of randomly picking a sample of n =25, 1-pound bags that average more than M = 13 shrimp per bag.
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Single bag:
[tex]\mu = 12.5, \sigma = 1.5[/tex]
Sample of 25 bags:
[tex]n = 25, s = \frac{1.5}{\sqrt{25}} = 0.3[/tex]
What is the probability of randomly picking a sample of n =25, 1-pound bags that average more than M = 13 shrimp per bag?
This is 1 subtracted by the pvalue of Z when X = 13. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{13 - 12.5}{0.3}[/tex]
[tex]Z = 1.67[/tex]
[tex]Z = 1.67[/tex] has a pvalue of 0.9525
1 - 0.9525 = 0.0475
0.0475 = 4.75% probability of randomly picking a sample of n =25, 1-pound bags that average more than M = 13 shrimp per bag.

Mark and his three friends ate out at Applebee's. (Hint* 4 total people) Their bill totaled $52.35. If they left the server a 20% tip, how much would each person pay splitting the bill evenly? (Round to the nearest dollar and cent)
Answer:
Unitary cost= $15.705
Step-by-step explanation:
Giving the following information:
Their bill totaled $52.35. They left the server a 20% tip.
First, we need to calculate the total cost of the meal:
Total cost= 52.35*1.2= $62.82
Now, we can split it into 4 equal parts:
Unitary cost= 62.82 / 4
Unitary cost= $15.705

Intercept form
Answer:
y=2x-3
Step-by-step explanation:
Y-intercept can be read off the graph.
Slope can be determined using the formula:
y2-y1 divided by x2-x1 (Substitute co-ordinates)
Answer:
y=2x-3
Step-by-step explanation:
y=mx+b
Where m is the slope and b is the y intercept
Slope is rise over run, the line is up 2 over 1
And the point of the line where it meets the y axis is -3. so b is -3
